Full textAbstract:
Bibliography: leaves 65-70.Low access to electricity is a problem in Africa. Apart from South Africa and Mauritius access to electricity generally falls below 30% of the population. The situation is even worse in the rural areas which housed about 70% or more of the population and whose access to modern energy services in these areas is between 5%-10%. Hence, this work aims at providing means of increasing access to electricity for the larger portion of the continent. This work looked at the potential of using bagasse, a waste from sugar production, to produce electricity beyond the sugar factory to the national grid. It shows that bagasse generated electricity can contribute to increasing this access in Africa as a whole by as much as 9.4 TWh, using Condensing Extraction Steam Turbines. However, this increase varies among countries with the highest being Swaziland, 67%, and the lowest South Africa, 1.5%, due to the current capacity. The actualization of this technical potential, however, can only come about with proper application of relevant policies and measures that need to be in place for Africa in general and South Africa in particular as more detailed work was done on the latter. Due to limitation in scope, this work did not cover the social, financial and agronomic aspects and neither was optimization of sugar considered in evaluating electricity from bagasse.

This thesis presents tha findings of an investigation into the use of energy, between the years 1975 and 1984, in five of the major energy-intensive industries in South Africa. Energy use in all economic sectors, from 1964 to 1974, was surveyed in the report "Energy Utilisation in South Africa", published by the Department of Planning and the Environment in 1978. As this report showed the major primary industries to be the largest single users of energy in South Africa, it was decided to isolate a number of major energy-intensive industries for investigation in this study. The 1979 Census of Manufacturing showed five industrial sectors to have consumed 41% by value of the total industrial energy consumption in that year, and it is those with which this thesis is concerned. The five industries are: The Structural Clay Products Industry, The Portland Cement Industry, The Glass Making Industry, The Iron and Steel Industry, The Pulp and Paper Industry.

Thesis (MDF)--Stellenbosch University, 2013.ENGLISH ABSTRACT: In 2007, Bürer and Wüstenhagen (2009) conducted a survey amongst European and United States venture capital and private equity investors (VC/PE) to ascertain their public clean energy policy preference and concluded that VC/PE investors view the feed-in tariff (FIT) scheme to be the most preferred policy option. In this research study, the author re-conducted part of the Bürer and Wüstenhagen (2009) survey with thirty South African VC/PE investors to determine their perceptions on clean energy public policy preference. It is evident from the survey, that opinions are varied and at times even contradictory. This in itself demonstrates an important feature of the South African VC/PE and clean energy industry: it is young, dynamic, changing rapidly and can look very different, depending on the vantage point. The investors surveyed were mainly optimistic about the long-term development of the South African renewable energy industry led by private investors. VC/PE investors in South Africa have mixed views on various investment options, and are concerned about both the regulatory and macro-economic trends. The interviews and survey results show a number of recurring issues. Altogether, the survey results indicate that VC/PE investors consider FITs to be the best public clean energy policy instrument in leveraging private investment and finance for renewable energy in South Africa. This study serves to illustrate and confirm, in line with empirical studies, that VC/PE investors in South Africa believe that clean energy market-pull policies provide an impetus and indeed spur private investor participation in clean energy in developing countries. While it is true that most VC/PE investors would prefer the price certainty associated with a FIT regime, this is almost an irrelevant question in South Africa since constitutionally the state is bound to procure through competitive tendering. This study also serves to highlight the need for more active research and attention in this field.

Full textAbstract:
Thesis (MBA (Business Management))--University of Stellenbosch, 2009.ENGLISH ABSTRACT: It has been established worldwide that energy efficiency undertakings are the fastest, most cost-effective and cleanest way to extend energy supplies. When the energy supply made available through energy efficiency projects are compared with increasing primary supply through building new conventional generation facilities, the former is in most cases also safer, more reliable and a more secure form of investment. Energy service companies (ESCOs) are the recognised implementation vehicles of energy efficiency projects and have been in use internationally for many years for this purpose. Globally, however, ESCOs do not have a good history of being viable business enterprises. The most important barriers identified internationally hindering ESCOs’ growth and sustainability were the potential customers’ lack of awareness, information and understanding regarding energy efficiency projects, the financing of these projects, as well as the support of government on energy efficiency policies and regulations. The urgency of implementing energy efficiency measures in South Africa is critical based on the precarious situation of the national electrical suppliers’ ability to provide electricity unfailingly to all its current and future customers. The South African electrical energy situation should therefore provide tremendous opportunities to the local ESCO industry. The aim of this study was therefore to reiterate the importance of energy efficiency projects and to describe the barriers to growth and sustainability experienced by ESCOs in South Africa against the international backdrop. This was done by way of a survey sent out to all registered ESCOs in South Africa. Based on the responses to the survey, the South African industry is in dire straits and is hindered by various barriers to their growth and sustainability. The study identified eight major barriers in the South African ESCO industry which are similar to those experienced by ESCOs internationally. The uniqueness of the local barriers however, is that the industry operates in a highly regulated environment and that these regulators, being the government and Eskom, are recognised as the main perpetrators responsible for most of these barriers, largely due to a lack of dedicated action. Furthermore, the study shows that it is critical for all role players in the South African energy efficiency industry, and specifically the South African government and Eskom, to recognise these barriers and to assist in solving them to improve the growth opportunities in the ESCO industry. Removal of these barriers will not only improve the electricity situation, but will also have a number of positive effects on the micro and macro-economic levels of South Africa, as well as the environment. Finally, the study makes suggestions about the way forward through a number of actions to be taken to lower or remove the most important of these barriers.
AFRIKAANSE OPSOMMING: Dit is reeds wêreldwyd bevestig dat energie-effektiwiteitsprojekte die vinnigste, kostedoeltreffendste en omgewingsvriendelikste manier is om energiebronne uit te brei. Wanneer die energieverskaffing wat beskikbaar gestel word deur energieeffektiwiteitsprojekte vergelyk word met die vermeerdering van primêre energie deur die bou van nuwe konvensionele opwekkingsfasiliteite, is eersgenoemde in die meeste gevalle ook veiliger en ’n meer betroubare en stabiele beleggingsvorm. Energie-diensmaatskappye (energy service companies (ESCOs)) is die erkende implementeringsmediums vir energie-effektiwiteitsprojekte en word reeds baie jare lank internasionaal vir hierdie doel aangewend. ESCOs het egter wêreldwyd nie ’n goeie rekord as lewensvatbare sake-ondernemings nie. Die vernaamste hindernisse wat ESCOs se groei en welvaart stuit is internasionaal geïdentifiseer as voornemende kliënte se gebrek aan bewustheid, inligting en begrip rakende energie-effektiwiteitsprojekte, die finansiering van sodanige projekte, asook die ondersteuning van die regering ten opsigte van energieeffektiewiteitsbeleide en -regulasies. Daar is groot dringendheid om energie-effektiewe projekte en maatreëls in Suid Afrika te implementeer, gebaseer op die huidige onsekerheid of die nasionale elektrisiteitsverskaffer wel in staat is om ’n betroubare bron van elektrisiteit aan sy huidige en voornemende kliënte te voorsien. Die Suid Afrikaanse elektriese energie situasie behoort daarom heelwat geleenthede te skep vir die plaaslike ESCO-industrie. Die doel van hierdie studie was dus om die belangrikheid van energie-effektiwiteitsprojekte te beklemtoon en om die hindernisse te omskryf wat ESCOs in Suid Afrika se groei en welvaart stuit, gesien vanuit ‘n internasionale perspektief. Dit was gedoen deur ‘n vraelys aan alle geregistreerde ESCOs te stuur. Na aanleiding van die terugvoering op die vraelyste, sukkel hierdie industrie om kop bo water te hou weens verskeie hindernisse wat hulle groei en welvaart stuit. Hierdie studie identifiseer agt belangrike hindernisse in die Suid-Afrikaanse ESCO industrie wat ooreenstem met die wat deur internasionale ESCOs ondervind word. Die uniekheid van die plaaslike hindernisse is egter dat die industrie werksaam is in ‘n streng gereguleerde omgewing en dat die reguleerders, die regering en Eskom, ook uitgewys word as die vernaamste skuldiges wat verantwoordelik is vir meeste van die hindernisse, hoofsaaklik as gevolg van hulle gebrek aan toegewyde uitvoering van take. Die bevindinge van hierdie studie toon verder dat dit krities is vir al die rolspelers in die Suid-Afrikaanse energie-effektiwiteitsindustrie, spesifiek die Suid-Afrikaanse regering en Eskom, om hierdie hindernisse te erken en om saam te werk om hulle te oorkom en sodoende die groeigeleenthede in die ESCO-bedryf te verbeter. Die verwydering van hierdie hindernisse sal nie alleen die elektrisiteitsituasie verbeter nie, maar sal ook ’n aantal positiewe invloede hê op die mikro- en makro-ekonomiese vlak van Suid-Afrika, sowel as die omgewing. Die studie sluit af met voorstelle rakende die uitvoering van verskeie aksies wat die verwydering van die vernaamste hindernisse tot gevolg sal hê, of die hindernisse se impak op die industrie sal verminder.

Thesis (MCom)--Stellenbosch University, 2015.ENGLISH ABSTRACT: Worldwide, energy has been, and continues to be, key to economic development. However, the current global consensus is that energy-related carbon dioxide emissions would, at current rates, put the world onto a potentially catastrophic trajectory which could lead to global warming of 5 degree Celsius or more compared to pre-industrial times. There is a critical need for a low-carbon development or a move away from conventional fossil fuels energy sources. This study explores impacts of policies that South Africa developed in order to champion sustainable energy strategies based on energy efficiency and non-conventional energy sources, including renewable energy. The mining sector, because of its energy-intensive nature, was chosen. In order to achieve this objective three approaches were carried out: (i) a critical review of literature on energy efficiency (EE) and renewable energy (RE) ; (ii) two case-studies that demonstrate the impacts of the policies; and (iii) action research on a sample of mines using survey questionnaire and interviewing. The research results show that the need to have security in energy and the need to be competitive and grow revenue are significant in deciding to carry out EE and RE initiatives in the mining sector. The results also show that safety followed by production are the priorities and are accompanied by a range of other demands, such as cost reduction and legislative requirements. It is, therefore, within this context that EE and RE initiative will always be carried out in the mining sector. The research concludes that, under the current market framework, South African EE and RE policies are not as effective as hoped they would be. The research, therefore, recommends that a percentage of the mines’ revenue could be dedicated to EE and RE initiatives. In addition, South Africa needs to come up with a new type of productive endeavour that would lead to less extractive industries, including mines.
AFRIKAANSE OPSOMMING: Energie is, was en sal wereldwyd altyd die sleutel wees tot ekonomiese ontwikkeling. Nieteenstaande, word dit wereldwyd aanvaar dat die huidige energie opwekking se koolstofdioksied vrystelling moontlik kan lei tot aardverwarming van 5 grade Celsius of meer wanneer vergelyk met word met pre-industriële tye. Daar is ‘n kritiese behoefte aan lae koolstofdioksied vrystelling ontwikkelings of ‘n beperking van konvensionele fossielbrandstof energiebronne. Hierdie studie analiseer die impak van die Suid Afrikaanse beleid wat ontwikkel is om volhoubare energie te bevorder wat effektief en onkonvensioneel is, insluitend hernubare energie. Die mynsektor, as ‘n groot verbruiker van energie, vorm die kern van die studie. Die studie is voltooi in drie fases naamlik: (1) kritiese oorsig van die literatuur oor energiedoeltreffendheid (EE) en hernubare energie (RE); (2) twee gevallestudies wat die impak van die beleid bevestig; en (3) praktiese navorsing deur middel van vraelyste en persoonlike onderhoude met seker myne. Die navorsing bevestig dat die behoefte aan bestendige energie teen kompeterende pryse wat die mynsektor in staat stel om inkomste te groei ,‘n beduidende invloed het op die besluit om EE of RE inisiatiewe te onderneem. Die resultate bevestig verder dat beroepsveiligheid en produksie uitsette die eerste prioriteite vir die myne is. Dit word verder beinvloed deur kostebesparings en wetlike vereistes. Enige EE en RE inisiatiewe wat onderneem word sal in hierdie konteks plaasvind. Die navorsing kom tot die slotsom dat, onder huidige marktoestande, Suid Afrika se EE en RE beleid nie so effektief is as waarop daar gehoop is nie. Die navorsing beveel derhalwe aan dat ‘n persentasie van myne se inkomste geoormerk moet word vir EE en RE inisiatiewe. Verder meer , Suid Afrika moet strewe na tipes produksie wat minder natuurlike grondstowwe onttrek, insluitend die myne.

Full textAbstract:
One of the greatest challenges facing the world today is integrating industrial activities such as mining with environmental integrity and social concerns. Monitoring is fundamental to environmental management, both to assess the adherence to standards and to allow environmental managers to learn from practical experiences. However, a problem arises when the regulatory authorities cannot keep up with their mandate of enforcement and compliance monitoring. This research examined how the Department of Minerals and Energy (DME) implements the concept of sustainable development in the mining sector of the Eastern Cape (EC) and, more specifically, the extent to which the Mine Environmental Management (MEM) section is able to effectively monitor compliance of mining operations with environmental legislation. This was the first systematic compilation of statistical data for the DME, and presents the first study in the EC regional office in terms of environmental sustainability. Results indicate that there has been a sustained increase in mining activity over the past three years, possibly as a result of the boom in the construction industry and the accelerated road maintenance and improvement programmes in the Eastern Cape. Mining applications received by the DME have increased by 47% from 2006 to 2007 (January-May) and by a further 100% from 2007 to 2008. In addition to the increasing number of mining concerns being established, 98 mining concerns will need to apply for the conversion of their old order rights to new order rights by the 1st May 2009. Mining in the province is predominantly small scale with mining permits (mined areas less than 1.5Ha) making up 52.3% of all applications, with larger mining concerns contributing 29.3% and prospecting contributing the remaining 18.4%. In terms of compliance inspections, the EC regional office is required to conduct 120 environmental compliance inspections annually in terms of contributing to sustainable development. The MEM section exceeded this target since 2003. However, when the number of operational mines is considered, 120 inspections per year equates to one mine being visited, on average once every four years (based on 2008 data). Based on projected figures (number of compliance audits and number of operational mines) for 2009, the DME’s target of 150 inspections for 2009/10 combined with the limited staff D. Watkins – MBA Dissertation 2008 capacity will, at best, mean that mines would be inspected once in seven years. However, the target of 150 inspections will not actually even cover the expected number of EMP evaluation inspections. This has serious implications in terms of regulating the compliance of the mining concerns with their EMPR’s. The low level of compliance monitoring can be directly related to staff capacity and logistics problems at the regional office as well as provincial targets being based on staff capacity rather than the number of operational mines. Thus, considering potential environmental damage associated with mining operations and the capacity constraints of the MEM to conduct frequent compliance audits, it is likely that mining operations will have negative implications for sustainable development in the region. Currently there are many challenges facing the DME in terms of contributing positively to sustainability in the mining sector and there is a need to base future actions on the idea of continuous improvement and ultimately progress.

Thesis (MBA (Business Management))--Stellenbosch University, 2008.ENGLISH ABSTRACT: The world today is facing many energy challenges such as power outages experienced internationally and in South Africa. The demand for energy is constantly increasing and is creating environmental problems such as climate change, which is presently a major concern to society. This study is an attempt to establish how energy saving mechanisms such as the elimination of non-essential power can add economic value within the mining industry. This paper examines the effect of non-essential power and how it could assist companies to reduce their energy consumption, aid local power utilities in a crisis and maintain normal production levels. This research report was based on an investigation for power saving opportunities at a mining company during a power crisis. The paper looks at energy efficiency and the barriers to the adoption of energy savings. Companies in general do not have a structured way of addressing non-essential power saving. Companies are not aware of the value such initiatives could have on corporate responsibility and sustainable reporting. The benefits of energy efficiency and nonessential power on the triple bottom line are not clearly documented in literature. When comparing the impact of non-essential power on the triple bottom line, it became obvious that further research is required in order to prove whether it influences the social aspect. The impact of power generation on the global environment has not been clearly calculated and linked to the value of saving power. The literature review highlighted that companies are focusing on long-term initiatives instead of smaller initiatives, which requires less effort. During the investigation of the mining company, it was found that not much effort was made during the design stages in separating the electrical circuits from non-essential and essential power. The author concludes that switching off non-essential power held economic and environmental benefits for the mining company. The author therefore concludes that switching off non-essential power impacts positively on the economic and environmental part of the triple bottom line. It was found that the elimination of non-essential power is easy to implement with minimum investment and effort. Furthermore, the savings from these initiatives could easily be measured to calculate the return on the investment.
AFRIKAANSE OPSOMMING: Ons kry deesdae al meer te doen met uitdagings soos internasionale en plaaslike kragonderbrekings in die energiebedryf. Die aanvraag vir energie verhoog deurlopend en veroorsaak omgewingsprobleme soos klimaatsveranderinge, wat ‘n groot bekommernis is vir die samelewing. In hierdie studie word gepoog om vas te stel hoe energie besparings meganismes soos die eliminering van nie-noodsaaklike krag ekonomiese waarde kan voeg tot die mynboubedryf. Die uitwerking wat nie-noodsaaklike krag het en hoe dit maatskappye kan help om kragverbruik te verlaag terwyl produksievlakke steeds gehandhaaf word, is hier ondersoek. Plaaslike kragvoorsieners kan ook baat vind hierby in krisistye. Hierdie navorsingsverslag is gebaseer op ‘n ondersoek van krag besparings geleenthede by ‘n mynmaatskappy gedurende ‘n krisistydperk van kragonderbrekings. Die verslag kyk na die doetreffendheid van energieverbruik, asook na die hindernisse wat ondervind word in die inwerkingstelling van energie besparings inisiatiewe. Maatskappye het in die algemeen nie ‘n gestruktureerde metode om die probleem rakende nie-noodsaaklike krag aan te spreek nie. Hulle is nie bewus van die nut wat sulke inisiatiewe kan hê op korporatiewe verantwoordelikheid en volhoubare verslaggewing nie. Die voordele wat energiebesparing en die eliminering van nie-noodsaaklike krag op die ekonomie, gemeenskap en omgewing het, word nie duidelik geboekstaaf nie. Verdere navorsing moet gedoen word om die impak van energiedoeltreffendheid en nie-noodsaaklike krag op die sosiale aspek te bewys. Die uitwerking wat kragopwekking op die globale omgewing het is nog nie bereken en verbind met die waarde daarvan op kragbesparing nie. Die verslag beklemtoon dat maatskappye fokus op langtermyn inisiatiewe in plaas daarvan om te kyk na kleiner inisiatiewe wat minder moeite en tyd sal verg. Die ondersoek by die mynmaatskappy het getoon dat daar nie klem geplaas is op die onderskeiding tussen nie-noodsaaklike en noodsaaklike krag met die installering van die elektriese stroombane tydens die ontwerpstadium nie. Daar is gevind dat die afskakeling van nie-noodsaaklike krag ekonomiese en omgewingsvoordele vir die maatskappy inhou. Daar is tot die slotsom gekom dat die afskakeling van nie-noodsaaklike krag in die algemeen dus ‘n voordelige uitwerking het op die ekonomie en omgewing. Dit is maklik om te implementeer met minimum moeite en belegging. Die besparings deur middel van hierdie inisiatiewe kan ook maklik gemeet word om die opbrengs op die belegging te bereken.

Through various policy mechanisms deployed in the last seven years, the South African government has pursued the localization of renewable energy manufacturing. These efforts are related to the Department of Trade and Industry's broader goals to industrialize the South African economy by increasing the range and value-add of domestically manufactured products. This thesis uses global value chain analysis to determine what ways local wind and solar manufacturing firms relate to this goal by pursuing innovation, upgrading, workforce development, and regional market penetration strategies. The author uses the theoretical framework of Vertically Specialized Industrialization (VSI) as outlined by Milberg, Jiang, and Gereffi as the basis for assessing firm-level governance strategies. The research was performed through semi-structured telephonic interviews with senior level staff at renewable energy firms and non-governmental organizations, as well as a review of public reports. The findings revealed that wind and solar firms are not significantly pursuing upgrading or innovation strategies as associated with VSI. This is likely the result of insufficient market demand and policy incentives, as well as competition from countries with comparative advantage.

Includes bibliographical references (p. 81-87).This thesis has drawn on Fine and Rustomjee's (1996) notion of the Minerals-Energy Complex (MEC) as a tool to analyse the relationship between industrial policy, energy use, and climate change mitigation policy in the South African context. The analysis finds that the South African economy has clearly developed in response to sets of industrial incentives offered both pre- and post-apartheid, which have structured the economy in such a way that electricity-intensive industry have come to dominate exports and investment in the country, but with very little positive effect on socio-economic development. This structure has a detrimental effect on possible mitigation actions; firstly because with the current development trajectory, it will be very challenging to meet mitigation targets as laid out in the country's Long-term Mitigation Scenarios (LTMS), and secondly because the mitigation wedges outlined in the LTMS will require significant shifts in the approaches, types and range of industrial policy measures that the country uses.

Thesis (MBA)--Stellenbosch University, 2006.ENGLISH ABSTRACT: The adoption of the White Paper on the promotion of Renewable Energy and clean fuels in 2003, opened the playing field for participants from other industries than the conventional petroleum, to participate in the fuel industry in South Africa. South Africa is a net importer of crude oil, which accounts for 92% of liquid fuels supply in South Africa. Although the country has significant coal reserves which can supply the country's demand for approximately 200 years, this energy source contributes significantly to CO, emissions. South Africa's participation in the Kyoto Protocol compels it to abide by its commitments to reduce these emissions between 2008 and 2012. The country's dependence on energy to fuel its growing economy, and the infiationary impact that oil imports has had on the country's economy, has prompted government to explore alternative sources of energy to reduce its dependence on fossil fuels and especially importing crude oil. As a result of this, and in an attempt to increase the potential for the successful implementation of ASGISA, government is exploring the feasibility of introducing an E10 fuel blend to the South African petrol blend. In view of th is, government has in it Accelerated and Sustainable Growth Initiative (ASGISA) targeted the development of the bio-fuels industry as an industrial sector that presents opportunities to create opportunities for sustainable growth and development. In view of this, the fiedgling fuel-ethanol industry (which is in its construction phase at the t ime of writing this report), faces lucrative prospects for the agricultural industry, especially maize- and ethanol producers. It is anticipated that the fuel-ethanol industry will create between 8000 and 10000 direct and indirect employment opportunities per plant. This will result in significant investment in rural areas as well. The creation of employment in the rural areas will prevent the large-scale urbanisation that has become a phenomenon in the past decade, as a result of dwindling agricultural industries. The production of ethanol presents the opportunity to earn foreign exchange, especially if the industry embarks on large scale export strategies. In addition to the export market, the local market for ethanol consist of the possible E10 petrol-blend and to supply Eskom with ethanol to fuel its gas turbine electricity generators at Acacia, Port Rex, as well as the anticipated generators at Atlantis and Mossel Bay. This document is a report on the investigation of the economic evaluation of a bio-fuel industry in South Africa. It will explore the current outlook for fossil fuel reserves, supplies and demand, both internationally and locally. It will report on the phenomenon of peak oil production and some opinions thereon . An investigation into the most probable biomass that can be used as feedstock for bio-fuel production will conducted. In this regard, specific investigation into maize, sugar cane (for fuelethanol) and Jatropha eureas (for bio-diesel) will be conducted. The report will explore the most efficient ethanol production processes, for both maize- and sugar-to-ethanol production, with the weight of the document to be attributed to the economic impact that the adoption of the fuel-ethanol programme
AFRIKAANSE OPSOMMING: Die publisering van die Witskrif oor die promosie van hernieubare energiebronne en skoon brandstowwe in 2003, het die speelveld vir deelname aan die brandstof industrie oopgemaak vir rolspelers buiten die konvensionele petroleum maatskappye. Suid-Afrika is 'n netto invoerder van ru-olie en het in 2004 ongeveer 92% van die totale vloeibare brandstowwe ingevoer. Alhoewel die land aansienlike steenkool reserwes het om te voorsien in die aanvraag vir die volgende ongeveer 200 jaar, dra hierdie energiebron aansienlik by tot die koolstofdioksied vrystellings. Suid-Afrika se deelname aan die Kyoto Protokol van 1998, dwing die land om te voldoen aan die ondernemings wat gemaak is om hierdie koolstofdioksied vrystellings te verminder tussen 2008 en 2012. Die land se afhanklikheid van energiebronne om groei te stimuleer, asook die inflasionistiese effek van olie invoere op die ekonomie, het die regering genoop om alternatiewe bronne van energie te ondersoek sodat die afhanklikheid van olie verminder kan word. Uiteenlopend hiervan en om die implementering van ASGISA te stimuleer, ondersoek die regering tans die moontlikheid om 'n E10 petrol vermenging in die petrol formule te spesifiseer. Uit die oogpunt van ASGISA (Accelerated and Sustainable Growth Initiative) van Suid-Afrika, het die regering die ontwikkeling van die bio-brandstowwe industrie geoormerk om geleenthede te skep vir volhoubare ontwikkeling en groei. Met die oog hierop, voorspel die etanol bedryf, wat ten tyde van die skryf van hierdie verslag nog in kontruksie was, winsgewende potensiaal vir die landboubedryf, veral mielie produsente. Dit word verwag dat die etanol bedryf tussen ongeveer 8000 en 10000 direkte en indirekte werksgeleenthede sal skep, veral in die landelike gebiede. Dit sal grotendeels bydra tot die voorkoming van die voortslepende ontvolking van die platteland wat oor die afgelope jare 'n verlammende effek op plattelandse gebiede gehad het. Dit word ook voorsien dat daar aansienlike belegging in die platteland sal plaasvind en al hierdie faktore sal bydra tot die voorkoming van verstedeliking . Die etanol bedryf skep die geleentheid om buitelandse valuta te genereer, veral as die industrie op uitvoere gaan konsentreer. Indien 'n plaaslike mark beoog word , sal die implementering van die E10 vermenging 'n besliste mark skep. 'n Alternatiewe mark wat ondersoek kan word, en wat groot geleentheid skep, is Eskom, wat tans ingevoerde diesel verbruik om hul gas turbine krag opwekkers by Acacia en Port Rex van brandstof te voorsien .

Full textAbstract:
The sugar beet (Beta vulgaris) plant has in recent years been added to the Biofuel Industrial Strategy (Department of Minerals and Energy, 2007) by the South African government as a crop grown for the production of bio-ethanol. Sugar beet is commonly grown in Europe for the production of sucrose and has recently been cultivated in Cradock and the surrounding areas (Engineering News, 2008). The biofuel industry usually ferments the sucrose with Saccharomyces cerevisiae to yield bio-ethanol. However, researchers are presented with a critical role to increase current yields as there are concerns over the process costs from industrial biotechnologists. The beet factories produce a pulp by-product removed of all sucrose. The hemicellulose-rich pulp can be degraded by microbial enzymes to simple sugars that can be subsequently fermented to bio-ethanol. Thus, the pulp represents a potential source for second generation biofuel. The process of utilising microbial hemicellulases requires an initial chemical pre-treatment step to delignify the sugar beet pulp (SBP). An alkaline pre-treatment with ‘slake lime’ (calcium hydroxide) was investigated using a 23 factorial design and the factors examined were: lime load; temperature and time. The analysed results showed the highest release of reducing sugars at the pre-treatment conditions of: 0.4 g lime / g SBP; 40°C and 36 hours. A partial characterisation of the Clostridium cellulovorans hemicellulases was carried out to verify the optimal activity conditions stated in literature. The highest release of reducing sugars was measured at pH 6.5 – 7.0 and at 45°C for arabinofuranosidase A (ArfA); at pH 5.5 and 40°C for mannanase A (ManA) and pH 5.0 – 6.0 and 45°C for xylanase A (XynA). Temperature studies showed that a complete loss of enzymatic activity occurred after 11 hours for ManA; and 84-96 hours for ArfA. XynA was still active after 120 hours. The optimised lime pre-treated SBP was subsequently degraded using various combinations and percentages of C. cellulovorans ArfA, ManA and XynA to determine the maximal release of reducing sugars. Synergistically, the highest synergy was observed at 75% ArfA and 25% ManA, with a specific activity of 2.9 μmol/min/g protein. However, the highest release of sugars was observed at 4.2 μmol/min/g protein at 100% ArfA. This study has initiated the research within South Africa on SBP and its degradation by C. cellulovorans. Preliminary studies show that SBP has the potential to be utilised as a second generation biofuel source.

Full textAbstract:
There is consensus that Eskom, South Africa’s main energy supplier, needs to expand its energy generating capacity in order to satisfy the growing demand for electricity, but there is less agreement on how it should do this. The existing supply is heavily reliant on thermal generation using coal, but the combustion of fossil fuels for electricity generation may contribute to climate change because it causes harmful greenhouse gases to be emitted into the atmosphere. This emission is something South Africa has committed itself to reducing. One way of achieving this is by the adoption of cleaner technologies for energy generation. One of these technologies is harnessing wind energy. The problem with harnessing wind energy is where to locate the turbines to harness the wind because these turbines ‘industrialise’ the environment in which they are located. They are a source of increased noise, a visual disturbance, cause increased instances of bird and bat mortality and the destruction of flora or the naturalness of the landscape in the areas in which they are located. The residents located near wind farm developments are most negatively affected and bear the greatest cost in this regard. A proper social appraisal of wind turbine projects would have to take this cost into account. Before such developments are approved there should be an assessment made of the impact on the residents, these impacts should be incorporated into the cost-benefit analysis. The negatively affected residents should also be compensated. The objective of this study was not to undertake a cost-benefit analysis of such a wind farm proposal, but to estimate the negative external cost imposed on nearby residents of such an industry, and thereby calculate appropriate compensation to be paid to these residents. Quantifying preferences for proposed, but not-yet developed, wind farms may be done by applying non-market valuation techniques, e.g. through one of the stated preference methodologies, such as a discrete choice experiment. The selected study site for providing guidance was one where Red Cap Investments Pty (Ltd) has proposed the development of a wind farm - in the Kouga local municipality. The basis for drawing conclusions was the analysis of the response samples of two groups of Kouga residents, distinguished by socio economic status; 270 from each group, 540 in total. The methodology applied to analyse the responses was a discrete choice experiment. The questionnaire administered included attitude, knowledge and demographic questions as well as a choice experiment section. The choice experiment section of the questionnaire required that the respondents choose between two different hypothetical onshore wind energy development scenarios and a status quo option. The hypothetical scenarios comprised different levels of wind farm attributes. The attributes included in the experiment were determined by international studies and focus group meetings. These attributes were: distance between the wind turbines and residential area, clustering of the turbines (job opportunities created by the wind farm development for underprivileged respondent group), number of turbines and subsidy allocated to each household. Three different choice experiment models were estimated for each socio-economic group: a conditional logit (CL), nested logit (NL) and a random parameters logit (RPL) model. It was found that, in the affluent respondent group, the simpler CL model provided the best fit. In the underprivileged respondent group, the RPL model, with the number of jobs created by the wind farm project as a random parameter1, explained by the gender of the respondent, provided the best fit. The estimated models identified distance as an important factor in both sampled respondent groups. Both respondent groups preferred that the wind farm be located further away from their residential areas. In addition to distance, the underprivileged respondent group also valued new job opportunities as an important determinant of choice. The affluent respondent group were very sensitive to densely clustered turbines but were almost indifferent between two of the effects coded levels of the clustering attribute “moderately close together” and “widely spaced apart”. Welfare estimates for the significant attributes in each socio-economic group were computed from the best fit models. Table 1 shows the resulting willingness to accept (WTA) compensation measures for distance in both socio-economic respondent groups.

Thesis (MPhil)--Stellenbosch University, 2014.ENGLISH ABSTRACT: Amid the climate change crisis of the 21st century, South Africa faces its own, tailor-made challenges. In its attempt to contribute to the global effort to mitigate climate change and achieve sustainable development, South Africa faces the challenge of a history steeped in cheap electricity - the curse of an abundance of coal. The municipality, as the lowest leg of governance, currently finds itself at a tough nexus, involving; municipal mandates to provide basic services; the possible financial risks of implementing RETs; the regulatory ambiguity surrounding electricity generation and distribution jurisdiction; and the necessary implementation of RETs as a means of addressing the growing risk of revenue loss from reduced electricity sales as consumers install their own RETs, and as a contribution to national climate change mitigation. This nexus is herein referred to as the ‘municipal dilemma’. This thesis, via a complex systems approach, explores the major barriers and policy opportunities in the implementation of renewable energy technologies (RETs) by municipalities embedded within the larger ambit of the South African government, as they attempt to address what the author has termed the ‘municipal dilemma’. What is especially interesting and relevant about a complex systems approach is the notion of learning and therefore adaptability. In light of municipalities and their role in the South African context, the notion of systems learning affords a unique perspective into the municipal dilemma and means of overcoming it. From a literature analysis of policy, through to a specific case study of Hessequa municipality, this study sought to assist municipalities in addressing this dilemma. South Africa’s energy and municipal management policies starting from the Constitution, is found to be conducive to the growth of RETs. Furthermore, there are clear channels through which municipalities can engage with these new technologies to address the municipal dilemma. What is seen to hinder this process is a web of institutional, political and regulatory barriers stemming from the over-politicization of the country’s energy sector - a direct result of a long history entrenched in coal-fired electricity generation. What was found lacking in the South African energy debate was the perspective of the municipality itself, which is ultimately tasked with catering for the energy needs of South African citizens while participating in national efforts. The notion that municipalities are best positioned to be influential in the growth of RETs is reinforced by the literature explored and through a complex systems approach. To effectively play their role, municipalities must: (a) be creative and bold in their development of appropriate policies to support RETs; (b) align their efforts with provincial and national programmes and simultaneously influence these programmes through municipal experience; (c) take advantage of systems in place, such as the Integrated Development Plan (IDP) process, to gradually build capacity within the municipality to manage increasingly complex RET implementation; (d) develop long-term strategies which, as per the tenets of complex systems theory, must feed from and into the ever-changing national and global landscape. This thesis posits that the municipal dilemma not only needs to be addressed, but offers the municipality a unique opportunity to rethink its role in the South African context. It has been found that a conducive regulatory environment is on the rise in the South African energy context. This environment, however, still requires much input from municipalities which are well positioned to offer direction to the policy creation process. In doing so, municipalities not only address the municipal dilemma, by also take their place as custodians of sustainable development.
AFRIKAANSE OPSOMMING: Te midde van die krisis van die 21ste eeu, naamlik die uitdaging van klimaatverandering, staar Suid-Afrika sy eie, unieke uitdagings in die gesig. Met die nodigheid om by te dra tot die globale poging om klimaatsverandering te versag en volhoubare ontwikkeling mee te bring, is Suid-Afrika gekonfronteer met die uitdaging van 'n geskiedenis ‘ryk’ in goedkoop elektrisiteit - die vloek van 'n oorvloed steenkool. Hierdienooreenkomstig bevind die munisipaliteit, as die laagste been van regering, homself in 'n moeilike krisispunt, naamlik die handhawing van die grondwetlike mandaat om basiese dienste te verskaf, en om ekonomiese ontwikkeling te verseker, maar tog by te dra tot die land se volhoubare ontwikkeling. Dit is uiters moeilik om alle aspekte genoegsaam aan te spreek, en hierna word verwys as die munsipale dilemma. Ter oorweging van die munisipaliteit as ingebed in 'n groter stelsel, naamlik die Suid-Afrikaanse konteks, en met 'n komplekse stelselsbenadering om die munisipale dilemma aan te spreek, ondersoek hierdie tesis die groot struikelblokke tot, en beleidsgeleenthede vir, die implementering van hernubare energietegnologie deur munisipaliteite. In terme van die komplekse stelsels benadering is veral belangrik die opvattings van leer en dus aanpasbaarheid van die stelsels en hul relevansie vir die Suid-Afrikaanse konteks. Uit 'n ontleding van die beleidsliteratuur, en deur ‘n spesifieke gevallestudie van Hessequa munisipaliteit, poog hierdie studie om munisipaliteite te help in die aanspreek van hul dilemma. Daar is gevind dat Suid-Afrika se energie- en munisipale bestuursbeleid, vanaf die Grondwet, die groei van hernubare energietegnologie bevorder. Verder is daar duidelike kanale waardeur munisipaliteite betrokke kan raak by hierdie nuwe tegnologie ten einde die munisipale dilemma aan te spreek. Hierdie proses word wel verhinder deur 'n web van institusionele, politieke en regulatoriese hindernisse, wat spruit uit die oorverpolitisering van die land se energie-sektor; 'n direkte gevolg van 'n lang geskiedenis verskans in steenkool-aangedrewe opwekking van elektrisiteit. Wat ontbreek in die Suid-Afrikaanse energie-debat is die perspektief van die munisipaliteit self, wat uiteindelik getaak is met die adressering van die behoeftes van die Suid-Afrikaanse samelewing, met gelyktydige deelname aan nasionale pogings. Die plaaslike en globale gevallestudies lig talle gemeenskaplike temas uit en vorm die basis van die gevolgtrekkings van hierdie tesis. Die idee dat munisipaliteite die beste geposisioneer is om invloedryk te wees in die groei van hernubare energietegnologie word versterk deur die literatuur ondersoek en deur middel van 'n komplekse sisteem benadering tot die gevallestudies. Om effektief te wees in hul rol, moet munisipaliteite (a) kreatief en dapper wees in hul ontwikkeling van toepaslike beleide om dié tegnologieë te ondersteun; (b) hul pogings in lyn bring met provinsiale en nasionale programme en terselfdertyd hierdie programme beïnvloed deur munisipale ervaring; (c) voordeel trek uit stelsels wat reeds in plek is om geleidelik kapasiteit op te bou binne die munisipaliteit om die toenemend komplekse hernubare energie implementering te bestuur; en (d) langtermyn strategieë ontwikkel in die steeds veranderende nasionale en internasionale landskap. Hierdie tesis postuleer dus dat die munisipale dilemma nie net aangespreek moet word nie, maar bied die munisipaliteit 'n unieke geleentheid om sy rol in die Suid-Afrikaanse konteks te heroorweeg. Wat bevind is, is dat toepaslike beleid reeds bestaan en dat munisipaliteite hul plek kan inneem as bewaarders van volhoubare ontwikkeling.

Thesis (MBA)--University of Stellenbosch, 2010.Climate change is one of the most serious issues the world is facing today. With an economic slowdown globally, huge food shortages and record-high fuel prices, it has never been so important for countries to guard their natural resources to ensure future sustainability. The South African energy generation industry, of approximately 40 000 Mega Watt (MW), consists largely (90%) of coal-fired power stations, with the remainder comprising of nuclear and pumped storage schemes which are regarded as environmentally neutral. It is only recently that Eskom and independent power producers (e.g. Darling Independent Power Producer Wind farm with an estimated 10 MW) embarked on utilising South Africa's natural resources to generate electrical power. South Africa's access to inexpensive coal and paid off coal-fired power stations has made it difficult to justify the investment in renewable energy. However, on 31 March 2009 South Africa became the first African country to introduce a feed-in-tariff for renewable energy (Gipe, 2009). The hope is that this initiative would stimulate the investment in green energy generation. Eskom and municipalities are currently the only entities that have licences from the National Energy Regulator of South Africa (NERSA) to buy bulk electricity from power producers. The question therefore arises: if green electricity is more expensive to generate and is sold at a price premium to Eskom and municipalities, would they pass the premium on to consumers; can they differentiate the green electricity product and will consumers be willing to buy at a premium price? This research study aims to answer if businesses would be willing to pay a premium for green electricity, why they would be willing to buy it, which factors influence the purchasing decision and what barriers exist that will deter a purchase. A survey was conducted on businesses in the Western and Northern Cape of South Africa. The businesses sampled have a notified maximum demand of 50kVA or higher and excludes the re-distributor (City of Cape Town) customers. Approximately ten per cent of businesses would be willing buy green electricity. Most of these businesses have indicated that they are willing to pay a premium of five to nine per cent for green electricity. The businesses that are willing to pay the largest premiums (>10%) are in the electricity, gas, water, finance, insurance, real estate, business services, manufacturing, transport, storage and communications sector. Businesses that are willing to buy green electricity: • Have a strategy to reduce their carbon footprint; • Want to be community leaders (altruistic motivators); • Have as their biggest barrier the additional cost of green electricity; and • Feel that power utilities should be required to include a minimum percentage of green energy in their energy mix.

Due to lack of generation capacity and high energy intensities South Africa's electricity supplier is forced to shut down high energy users frequently. Power cuts as well as escalating electricity prices threaten the country's steel industry. The objective of this study was to identify cost-effective energy efficiency improvements for the South African foundry industry. A lack of research in South African foundries was identified as existing literature on the topic was analysed. A large foundry operating an induction furnace in the Western Cape served as subjects to investigate the topic specifically in South Africa. The aim was to identify the energy intensity, evaluate already implemented energy efficiency measures and identify further opportunities to reduce energy cost of the foundry. The method followed for the data collection was much orientated on an industry energy audit. Types of energy, amounts and cost of energy usage were determined. The energy consumption and energy intensity of the foundry were analysed, based on meter readings, electricity bills and where necessarily a "bottom-up" approach for estimation was used. Results of the energy audit have shown that the foundry under review consumes about 127,000 MWh annually with a maximum demand of 26,500 kVA. The already implemented energy saving measures decreased the company's energy usage by 5% resulting in a current energy intensity of 1,493ZAR/ton. Further proposed energy efficiency measures included the compressed air system, preheating of the charge material and the reduction of the holding furnaces were analysed. The results of all evaluated measures, namely lighting, load-shifting and maximum demand management were cost effective solutions. Furthermore the recommended energy efficiency measures, namely reduction of compressed air leaks, reduction of holding furnaces as well as preheating of charge material, showed in theoretical calculations a reduction of carbon emissions as well as cost savings. This study offers an insightful view on energy intensity and energy efficiency opportunities in South African foundries, especially the ones operating an induction furnace.

Bibliography: pages 130-134.Poor rural communities of South Africa frequently face shortages of convenient, affordable energy services. Sub-sectoral energy interventions that are not properly coordinated with each other and with the development context are unlikely to address the problems effectively. The methodology of 'integrated rural energy planning' (IREP) is a possible means of achieving this coordination. This process encompasses a new paradigm which is an improvement on the supply-driven thinking of the past. It seeks to overcome anomalies in the rural energy system in a way that places the final users of energy services at its centre, that coordinates planning between different energy sub-sectors, and integrates energy planning with economic planning processes. It emphasises continuity, efficient utilisation of resources, and genuine participation of rural people. Although originally designed for the energy sector as a whole, the theoretical methodology is applicable to rural regions of developing countries with only small modifications. International and local experience in IREP is not extensive, but it nevertheless provides valuable lessons regarding methodological and institutional requirements. The current trends in the institutional framework in South Africa show that while there are many obstacles to implementing an IREP process, there are also many unique aspects which suggest that an IREP process could be very effective. It seems clear that an appropriate way forward would be to launch a well-resourced and strategically-located initiative that would investigate, with care and foresight, the potential and relevance of an IREP process in South Africa.

Conceptualising energy security is of the upmost importance when considering any
definition of energy security applicable to a country or geographical context. This
conceptualisation leads to the definition and allocation of applicable influencing
elements, that ultimately underpin this definition, but more importantly lead to policy and
the associated legislation formulation. A major contributing factor to energy security for
any country is the understanding of the relationship between economic growth and
energy consumption. There are various phases (Growth, Conservation, Neutral and
Feedback hypothesis) of this relationship and each is represented by a different causal
direction. This relationship forms a critical factor to consider when conceptualising
energy security. A Second critical factor underpinning energy security is the selection of
the appropriate electricity generation mix. Currently South Africa is dominated by coal as
energy source, with nuclear, gas, diesel and recently renewable sources that contribute
electricity to the national grid. Much of the worlds, including South Africa, generation fleet
is reaching end of life and is standing at a pivotal point having to decide on the
appropriate energy mix that allows transitioning to an environmentally friendly generation
fleet.
This research set out to review the South African energy policies to ascertain whether
the encapsulated elements are still valid and current, to review the historical 3 :2
economic growth and energy consumption relationship utilised in the Integrated
Resource Plan 2010 formulation to determine its validity and ultimately to explore the
possibility of a 100% renewable energy generation profile for South Africa. A case study
methodology was employed, where interviews with industry experts were analysed and
validity of emerging themes plaid with the introduction of secondary data.
The research has found that i) the current definition of energy security, as stipulated in
the South Africa Energy Master Plan (2007), is out of date and needs revision, ii) the
historical 3 :2 economic growth and energy consumption relationship is out of date and it
is recommended that a bottom up sectoral analysis be done to determine the current
relationship and iii) the a 100% renewable energy generation profile for South Africa is
not currently feasible until such time as electricity storage becomes an economical viable
option.Mini-disseration (MBA)--University of Pretoria, 2015.

This paper presents the outcome of two case studies and a survey of manufacturing and engineering industries in the Eastern Cape, to explain their environmental education and / or training needs. The methods involved in case studies were interviews, observation and document analysis and for the survey a postal questionnaire. Respondents were generally able to identify their companies' environmental impacts and most thought that education and/training has a role to play in helping them deal with those impacts. While respondents identified environmental awareness for workers as the main role that education and / or training can play, it also has to help management understand its environmental role in dealing with environmental management systems and legislation, as well as supporting education and training. Education and/or training should take both managers and workers beyond the superficial understanding of the concept of environment. In-house and external trainers were identified as potential trainers as this would both overcome a current lack of capacity and make continuity possible when external trainers cease training. Trainers should be environmentally qualified. Respondents have mostly shown support for learning-on-the-job but less so on special environmental courses or including an environmental component in all training programmes. Some training sections consider their sections as already overladen and unable to accommodate other training programmes. The problem is therefore more logistic than environmental.

Full textAbstract:
The implementation of independent utility-scale renewable energy projects in South Africa has only recently been adopted en masse and with new initiatives, numerous barriers and challenges have arisen making for a complex and ambiguous environment. The requirement for cheap and clean energy generation has been emphasised by the need for climate change mitigation initiatives, the increasing need for energy to grow the economy and the problems encountered by South Africa's monopolistic energy parastatal to maintain their coal-fired power plant and produce sufficient quantities of electricity. In any fledgeling industry, the skills are generally lacking, meaning that there is a need for academic institutions to fill the need for skills transfer as well as companies to ensure that there are skills transfer initiatives in place. The study explored these challenges and barriers from the viewpoint of developers and Engineering, Procurement and Construction Management companies in particular in the context of South Africa's Renewable Energy Independent Power Producers Programme.
In order to ensure that a complete set of factors were considered during the study, the Enterprise framework for renewable energy was utilised as a structure that draws attention to a wide range of both internal and external barriers in the renewable energy sector. This framework and literature pertaining to the barriers experienced thus far gave rise to four research questions which were utilised as the basis for the interview questions. To draw from the experience of those who have been involved in the RE IPPPP, 11 in-depth, exploratory interviews were conducted from those with differing positions from a diverse selection of organisations.
The study determined that there are seven main barriers and challenges in the sector and that the vast majority of factors emanate from the external environment. It was also found that skills and skills development have been successful especially in the technical areas, but lacking at management and government level. The study culminated in a framework to assist developers and EPCM companies in the renewable energy sector to take cognisance of the challenges and barriers and the factors that create the said challenges and barriers. Recommendations to EPCM companies, management and government and policy makers were formulated. These include policy changes, the reassessment of the Eskom's corporate structure and opportunities in embedded energy production. Recommendations were also made with regards to future research.Mini Dissertation (MBA)--University of Pretoria, 2017.

Thesis (MPhil)--Stellenbosch University, 2015.ENGLISH ABSTRACT: South Africa is one of the most energy-intensive economies in the world, with around 90 per cent of its electricity generated using coal as a primary resource. As such, the South African energy system remains on a highly unsustainable path, and the potential for long-term growth and prosperity of the economy is thwarted. The alternative to conventional energy, renewable energy, has unfortunately been relatively slow to take off in the South Africa market. This is disappointing considering the country’s wealth of natural resources required for renewable energy generation. The potential of renewable energy to contribute to the South African energy mix is thus significant. The transition to a green economy, and subsequently a more sustainable energy future, is therefore achievable and realistic. However, national policies aimed at promoting the deployment of renewable energy have been thwarted by inconsistencies, lack of coordination, and proved relatively ineffective at increasing the country’s renewable energy capacity to its full potential. The recent policy changes from a feed-in tariff to a competitive tender approach dented investor confidence in the South African renewable energy industry significantly. Nevertheless, renewable energy policy in South Africa is still in its infancy, and valuable lessons are still to be learnt and incorporated into future policies going forward. A critical analysis of the current policy identifies the need for amendment to the structure of the policy landscape. The current policy strongly favours larger, more established and mature renewable technologies, whilst completely neglecting smaller and less mature ones. This not only results in a highly undiversified renewable energy mix, which has considerable negatives in itself, but also reduces the ability of the policy to capture a host of significant opportunities and advantages associated with small-scale renewable energy projects. The importance of diversifying South Africa’s renewable energy mix was therefore ones of the principal stances of this study, and intervention that ensured diversification within the industry was therefore vital. This study fundamentally designs and proposes a revised policy system that makes use of both competitive tenders and feed-in tariffs within the policy framework. In essence, this would allow for greater diversification within the renewable energy industry. The competitive tender component should be used for larger, more established technologies and projects, while the feed-in tariff should be used to drastically stimulate investment in smaller technologies and projects. By making use of a dual-mechanism system, the benefits associated with small-scale renewable energy projects can be realized without any noteworthy opportunity costs foregone. These benefits include diversification of the renewable energy mix; stimulation of smaller technologies; increased job creation; and stabilisation of supply volatility. This study recommends that the current renewable energy policy in South Africa be reassessed for both its relevancy within the South African context as well as its ability to effectively promote the deployment of alternative energy technologies. In an ever-changing and globalising world, where exogenous influences on national policies are stronger than ever, it becomes necessary and of utmost importance that policies are evaluated constantly in order to ensure their effectiveness is at optimal level.
AFRIKAANSE OPSOMMING: Die Suid-Afrikaanse ekonomie is een van die energie-intensiefstes ter wêreld, met steenkool as hoofbron vir sowat 90 persent van die land se kragopwekking. Die Suid-Afrikaanse energiestelsel as sulks bly dus op 'n onstabiele pad, en die potensiaal vir langdurige ekonomiese groei en welvaart word geknel. As teenvoeter vir konvensionele krag het hernubare energie steeds stadig veld gewen in die plaaslike mark – wat teleurstellend is as die land se rykdom aan natuurlike bronne vir hernubare energie-opwekking in ag geneem word. Hernubare energie het dus 'n aansienlike potensiaal om tot die Suid-Afrikaanse energiemengsel by te dra. Die oorgang na 'n groen ekonomie, en gevolglik na 'n volhoubaarder energie-toekoms, is daarom bereikbaar en realisties. Nasionale beleide oor hoe die uitrol van hernubare energie bevorder word, is egter tot dusver gestrem deur ongereeldhede en 'n gebrek aan koördinasie, en was gevolglik relatief ondoeltreffend om die land se hernubare energiekapasiteit ten volle te verhoog. Die onlangse beleidsveranderinge vanaf 'n toevoertarief na 'n mededingende tenderbenadering het beleggersvertroue aansienlik geskaad. Suid-Afrika se hernubare energiebeleid is nietemin nog in sy kinderskoene, met kosbare lesse wat geleer kan word en vir die pad vorentoe in toekomsplanne ingewerk kan word. 'n Kritiese ontleding van die huidige beleid wys hoe nodig 'n aangepaste struktuur vir die beleidsraamwerk is. Die huidige beleid begunstig groter, meer gevestigde en ontwikkelde tegnologieë terwyl kleiner en minder ontwikkeldes heeltemal afgeskeep word. Dit het tot gevolg nie net 'n hoogs ongediversifiseerde mengsel van hernubare energie nie, wat op sigself 'n aantal nadele inhou, maar boonop verminder dit die beleid se vermoë om vele betekenisvolle geleenthede en voordele aan te gryp wat gepaard gaan met kleinskaalse projekte vir hernubare energie. Dat die diversifisering van Suid-Afrika se hernubare energiesamestelling belangrik is, was dus een van dié studie se hoofbenaderings, asook dat ingryping ter wille van diversifisering binne die bedryf onontbeerlik is. Hierdie studie bied 'n ingrypende ontwerp en voorstel vir 'n hersiene beleidstelsel, met mededingende tenders asook toevoertariewe binne die beleidsraamwerk. Dit sal in wese ruimte laat vir groter diversifikasie binne die hernubare energiebedryf. Die mededingende tendergedeelte behoort vir groter, meer gevestigde tegnologieë en projekte gebruik te word, terwyl die toevoertariewe kan dien om belegging in kleiner tegnologieë en projekte te stimuleer. Deur 'n stelsel van tweeledige meganismes kan die voordele van kleinskaalse hernubare energieprojekte realiseer sonder die inboet van noemenswaardige geleentheidskoste. Dié voordele sluit in, om enkeles te noem, die diversifikasie van die hernubare energie-toneel; die stimuleer van kleiner tegnologieë met gepaardgaande groter werkskepping; en toenemende plaaslike produkvervaardiging. Met dié studie word aanbeveel dat Suid-Afrika se huidige beleid oor hernubare energie heroorweeg word, rakende die relevansie daarvan binne die landskonteks asook die beleid se vermoë om die ontplooiing van alternatiewe energietegnologieë doeltreffend te bevorder. In 'n voortdurend veranderende en globaliserende wêreld, met buite-invloede op nasionale beleidsrigtings sterker as ooit, word dit noodsaaklik en uiters belangrik dat beleide voortdurend heroorweeg word om die doeltreffendheid daarvan op die gunstigste vlak te verseker.

Full textAbstract:
The purpose of the research was to discover if the dismantling of apartheid had ameliorated the poor pay and conditions of domestic servants in the Eastern Cape, South Africa. I situated these workers in the wider societal context in order to examine their 'quality of life' in addition to their 'quality of work'. Universal features of domestic service have been the depersonalising of the worker and the denial of their adulthood to that of a child. Enriching the data with consideration of some of the life details of the domestic servants interviewed challenges these lingering social practices. I favoured an interpretive methodology in order to give my interviewees the opportunity to 'speak for themselves' and facilitate the exploration of the hidden meanings within the domestic service relationship. Having argued through the thesis that domestic servants are often social constructed, caricatured and 'trapped' into being the 'other', their words are a reaffirmation of their adult status. Hegel's Lordship/bondage paradigm was the starting point of the theoretical analysis, from which I developed my own 'chains of otherness' conception. I sacrificed representativeness in my sample in order to focus on contextualising my theoretical arguments in nine diverse case studies. The outcome was that my research question narrowed to considering improvements in the lives of my nine domestic workers interviewed. However, I have also incorporated quantitative data within the thesis to add depth to my investigation. Grahamstown was the deliberate choice for the research site, as this was also the site of Cock's (1989/79) much-cited Maids and Madams. To return to an original area of investigation was imperative, as within the remit of the research question being asked was a comparison of domestic service during and after apartheid. The distortions of regionalism were minimalised and validated my use of Cock's results as a starting point for my own findings. Mandela's book title Long Walk to Freedom is an apt description of what I discovered. Improvements are beginning to be made but there is still much more to be achieved. Domestic service's inclusion in the ambit of labour legislation and improved conditions of work are positive shifts, but wages are still extremely low and social practices still have racial orientations. In addition to the application of my theoretical arguments, I moved beyond answering the original research question to consider the effects of poverty in the lives of domestic workers and formulated strategies of empowerment. As the thesis has favoured a qualitative approach I not only considered the material factors that are necessary to empower, but also the interrelations between one another that can recognise and promote human dignity.

Bibliography: leaves 168-173.In this thesis the energy sector of the East and Southern Africa Region (as defined by the World Energy Council) is investigated. Special attention is given to South Africa and the potential future role she could play in the region. The region is characterized by large population growth rates, insufficient economic growth, political and civil instability, massive urbanization, high illiteracy rates, a low level of development, a lack of finance and foreign exchange, and inadequate institutional structures, all of which effect the energy sector making the provision of a sustainable and adequate supply of energy difficult. On the other hand, South Africa, the economic giant of the region, has a sophisticated and well established energy infrastructure and•has the potential to play a large role in the energy sector of the region. A large portion of the region's energy demand is supplied by traditional energy sources and is consumed by the domestic sector. In many countries of the region, energy demand exceeds sustainable supply, resulting in energy scarcities and increased deforestation. These issues need to be addressed as a priority. Reforestation based on agro- forestry, was identified as the option most likely to succeed in this regard. Although commercial energy resources are abundant within the region, they are largely unexploited as a result of the lack of suitably large markets, vast distances, a lack of finance and regional instability. The promotion of the utilization of these resources, which would ease supply constraints, is reliant on regional cooperation and the trade in energy. Forecasts of future energy consumption in the region indicate that unless present constraints on the energy sector are alleviated, the adequate supply of energy, and in particular traditional energy, will be jeopardized. It is proposed that any long-term cost-effective solution for the provision of an adequate and sustainable supply of energy requires regional political stability and cooperation, institutional reform, the integration of traditional and commercial energy structures, and should address the issues of deforestation and population growth.

Thesis (MTech (Electrical Engineering))--Cape Peninsula University of Technology, 2010.In recent years, the South African hotel industry has experienced increasing demand for hotel's services. At the same time, mounting costs of energy affects energy performance and public image. Energy management is a new approach to address those widespread problems. This study aimed to suggest good management practices and develop a "self-help" approach, to reduce the demand and costs of energy for the South Africa hotel industry. This is expected to result in monetary savings and conservation of energy resources. This has been done by conducting survey within seven selected hotels in Cape Town, metropolitan of South Africa. In addition, through the "self-help" guide, approaches to energy management system are also described, showing the ways for hotels to achieve better energy performance. Potentials for savings from good housekeeping are estimated to 10 - 15%. The "self-help" guide is recommended to be improved through implementation in pilot hotels; and the proposal set of benchmarks need to be different for hotels in different provinces of South Africa considering the differences in climate conditions. The result of this study range from presenting the energy conservation awareness, barriers, method of conservation, financial and institution mechanisms, policy measures, status of energy use and propose strategy to develop a "Self-help" guide for energy management in South African Hotel industry. It has been found that energy monitoring has been done in the South African Cape Town hotels. From the total energy consumed by this industry, electricity accounts 80% of it of which air conditioning takes the biggest share (about 50%) and the remaining for Liquefied Petroleum Gas (LPG), diesel and others fuels. In addition, through the "self-help" guide, approaches to energy management system are also described, showing the ways for hotels to achieve better energy performance.

Full textAbstract:
Electricity supply industries (ESI) around the world are subject to structural and regulatory change. The environmental implications of these changes will depend, largely, on future investment within cleaner technologies. As developing countries (Des) increase levels of electricity supply, the incentives for investment in clean technologies is particularly important. Policy-makers wishing to promote renewable electricity technologies (RETs) in Des need to understand the nature of technological change in large technical systems (LTS). Broadly this thesis adopts the view that technological change is the outcome of the complex interaction of technical, economic and political factors. Initially technological change in LTS is shaped by social and political factors. As the system increases in both size and complexity driven by economies of scale and scope, and through co-evolution of technical and institutional features, it exhibits 'momentum,' whereupon technological change tends to be 'incremental' and autonomous. Through problem-solving activities to address 'reverse salients' the system evolves on a 'technological trajectory,' its path confined by technological and economic boundaries defined by the prevailing 'techno-economic' paradigm. Subsequently new technologies such as RETs, with characteristics different to those of the 'Traditional Electricity System Trajectory' (TEST) are unlikely to be favoured. Restructuring the electricity system provides a discontinuity in its momentum, allowing the drivers and interactions of different stakeholders to be more transparent. During such periods of instability there are important opportunities for systemic change through meaningful policy input. The socio-economic importance of electricity supply in Des further increases the 'technoinstitutional complexity' within the electricity system, and so resistance to restructuring. The thesis argues that restructuring of the ESI is a necessary, but not sufficient requirement for commercialisation of RETs. Rather policies supported by legislation should ensure that conservative techno-institutional mechanisms are replaced by ones that encourage a 'Balanced Electricity System Trajectory.' The BEST framework incorporates 'economies of the system' as a driver and is characterised by distributed technologies including small-scale and modular generation and sophisticated control technologies. As well as being characterised by flexible control in the technical sense, the BEST model is also characterised by flexible institutional arrangements.

ENGLISH ABSTRACT: Technology assessment has changed in nature over the last four decades. It changed from an analytical tool for technology evaluation, which depends heavily on quantitative and qualitative modelling methodologies, into a strategic planning tool for policy-making concerning acceptable new technologies, which depends on participative policy problem analysis. The goal of technology assessment today is to generate policy options for solutions of organisational and societal problems, which at the operational level, utilise new technologies that are publicly acceptable; that is, viable policy options. Energy technology assessment for sustainability is inherently a complex and dynamic process that requires a holistic and transdisciplinary approach. In the South Africa context, specifically, there is no formal and coherent approach to energy technology assessment from a sustainability perspective. Without a formal comprehensive or well integrated technology assessment approach to evaluate the sustainability of any technology, the policy-makers, technology designers, and decision-makers are faced with difficulty in terms of making reasoned decisions about the appropriate technology options. This study developed a framework that incorporates a technology assessment approach, namely, system dynamics, within the broader scope of technology development for sustainability. The framework, termed the Systems Approach to Technology Sustainability Assessment (SATSA), integrates three key elements: technology development, sustainable development, and a dynamic systems approach. The study then provides a guiding process of applying the framework to energy technology assessment theory and practice within the context of sustainable development. Biodiesel, a cleaner burning replacement fuel, argued to potentially contribute to sustainable development, is used for the demonstration. Biodiesel development entails complex interactions of actors such as the technology developers, government at different levels, communities, as well as the natural environment. Different actions or responses in the greater system might hinder or undermine the positive effects of such a development. Based on the SATSA framework, a Bioenergy Technology Sustainability Assessment (BIOTSA) model was developed. The BIOTSA model was used to test the outcomes of a proposed biodiesel production development in the Eastern Cape Province of South Africa on selected sustainability indicators. In addition, some policy scenarios were tested to compare how they assist in improving the selected indicators. The BIOTSA model results are useful in comparing dynamic consequences resulting from a proposed biodiesel production development and the respective policies and decisions that may arise from such a development. The testing and validation of the BIOTSA model was carried out based on structural validity, behavioural validity, and expert opinion. Potential policy scenario outcomes and their implication, on the selected sustainability indicators, were also tested. The opinions of the selected stakeholders indicated that the BIOTSA model was useful in providing an understanding of the potential impacts of the biodiesel development on selected sustainability indicators in the Eastern Cape Province. Thus, the SATSA framework can be applied for assessing sustainability of other renewable energy technologies. In addition, system dynamics provide a useful and a feasible dynamic systems approach for energy technology sustainability assessment. Finally, the model building process and transdisciplinary nature of this study enabled the identification of the potential problems that could arise during the biodiesel production development. In addition, gaps in data and knowledge were identified and the recommendation for future work in this field is highlighted. Nevertheless, the findings of the BIOTSA model could inform policy- and decision-making in biodiesel production development in South Africa. The development of similar models for other renewable energy development efforts is thus recommended. The current efforts to facilitate the large-scale roll out of concentrated solar thermal technologies in Southern Africa, for example, would require the development of a Solar Thermal Technology Sustainability Assessment (SOTTSA) model.
AFRIKAANSE OPSOMMING: Die aard van tegnologie assessering het in die afgelope vier dekades verander. Dit het verander ten opsigte van ’n analitiese hulpmiddel vir tegnologie evaluering, wat hoofsaaklik staatmaak op kwalitatiewe en kwantitatiewe modelleringsmetodiek, na ’n strategiese beplanningshulpmiddel vir beleidvorming met betrekking tot nuwe aanvaarbare tegnologieë, wat afhanklik is van ’n deelnemende beleidsprobleem analise. Vandag se doel vir tegnologie assessering is om beleidsopsies vir oplossings van organisatoriese en sosiale probleme te genereer, wat op operasionele vlak gebruik maak van nuwe tegnologieë wat deur die publiek aanvaar is; met ander woorde, lewensvatbare beleidsopsies. Energie tegnologie assessering vir volhoubaarheid is sonder twyfel ’n komplekse en dinamiese proses wat ’n holistiese en transdisiplinêre benadering benodig. In die Suid- Afrikaanse konteks is daar geen formele en samehangende benadering tot tegnologie assessering vanaf ’n volhoubaarheidsperspektief nie. Beleidsmakers, tegnologie ontwerpers en besluitnemers mag sukkel om beredenerende besluite te neem oor die toepaslike tegnologie opsies sonder ’n formele omvattende of goed geïntegreerde tegnologie assesseringsbenadering om die volhoubaarheid van enige tegnologie te evalueer. Hierdie studie het ’n raamwerk ontwerp wat die tegnologie assesseringsbenadering inkorporeer binne die breë bestek van tegnologiese ontwikkeling vir volhoubaarheid naamlik, stelsel dinamika. Die raamwerk, genoem die Sisteem Benadering tot Tegnologie Volhoubaarheidsassessering (SBTVA) integreer drie sleutelelemente: tegnologiese ontwikkeling, volhoubaarheidsontwikkeling, en ʼn dinamiese stelsels benadering. Verder verskaf die studie ’n leidende proses te opsigte van die toepassing van die raamwerk tot energie tegnologie assesseringsteorie en praktyk binne die konteks van volhoubaarheidsontwikkeling. Biodiesel word gebruik vir die demonstrasie omdat dit gereken word as ’n skoner plaasvervanger vir brandstof en daar aangevoer word dat dit ’n potensiële bydraer tot volhoubaarheidsontwikkeling is. Die ontwikkeling van biodiesel behels komplekse interaksie tussen verskeie akteurs soos tegnologiese ontwikkelaars, die regering op verskillende vlakke, gemeenskappe asook die natuurlike omgewing. Verskeie aksies of reaksies in die groter sisteem mag dalk die positiewe effek van so ontwikkeling ondermyn of verhinder. ’n Biodiesel Tegnologiese Volhoubaarheidsassessering (BIOTVA) model is ontwerp gebaseer op die SBTVA raamwerk. Die BIOTVA model is gebruik om die uitkomste op geselekteerde volhoubaarheidsaanduiders van ’n voorgestelde biodiesel produksie ontwikkeling in die Oos- Kaap Provinsie van Suid-Afrika te toets. Buiten vir die voorafgaande is sekere beleidtoekomsblikke ook getoets om te vergelyk hoe hulle sal help om die geselekteerde aanwysers te verbeter. Die BIOTVA model resultate is behulpsaam in die vergelyking van dinamiese gevolge wat voortspruit uit die voorgestelde biodiesel produksie ontwikkeling asook die onderskeie beleide en besluite wat mag ontstaan van so ’n ontwikkeling. Die toetsing en bekragtiging van die BIOTVA model was uitgevoer gebaseer op strukturele geldigheid, gedragsgeldigheid, en kundige opinie. Potensiële beleidtoekomsblikke uitkomste en die nagevolge, ten opsigte van die geselekteerde volhoubaarheidsaanduiders, is ook getoets. Die opinies van die geselekteerde aandeelhouers het aangedui dat die BIOTVA model bruikbaar is om ’n beter begrip te verskaf ten opsigte van die potensiële impak wat die biodiesel ontwikkeling op geselekteerde volhoubaarheidsaanduiders in die Oos-Kaap Provinsie sal hê. As gevolg hiervan kan die SBTVA raamwerk toegepas word om die volhoubaarheid van ander herwinbare energie tegnologieë te assesseer. Buiten die voorafgaande kan stelsel dinamika ’n bruikbare en uitvoerbare dinamiese stelselbenadering vir energie tegnologie volhoubaarheidsassessering verskaf. Ten slotte, die model bouproses en transdisiplinêre aarde van die studie het gehelp om potensiële probleme wat kan voorkom tydens die biodiesel produksie ontwikkeling te identifiseer. Daarby is gapings in data en kennis ook geïdentifiseer en die aanbevelings vir verdere studie in die veld is uitgelig. Nieteenstaande kan die bevindings van die BIOTVA model beleidmakers en besluitnemers in die biodiesel produksie ontwikkeling van Suid- Afrika inlig. Die ontwikkeling van soortgelyke modelle vir ander herwinbare energie ontwikkelingspogings word aanbeveel. As voorbeeld sal die huidige pogings om die grootskaalse uitrol van gekonsentreerde son termiese tegnologieë in Suider-Afrika te fasiliteer die ontwikkeling van ’n Son Termiese Tegnologie Volhoubaarheidsassesering (SOTTVA) model benodig.

Thesis (PhD (Electrical Engineering))--Potchefstroom University, 1993.The domestic sector is one of the largest users of nett energy in the RSA (24%, excluding energy used for transport), but it accounts for only 14% of the electrical energy used in the RSA. There is a very strong correlation between the time of the peak of the load for the domestic sector and the time of the peak of the national load. The domestic load is the largest contributor to the peak of the national load. This makes the domestic load more important than is generally realised. Only limited research has been done about the ways in which domestic energy is used in South Africa. Developed countries, such as the United States of America, are continuously engaged in end-use load research, so they have vast data banks available on domestic end-uses of electricity. Data on domestic end-use of electricity are urgently needed especially for South Africa with its very fast growing newly urbanised sector. Since most energy sources are not replenishable, ways and means must be found to promote the wise and effective use of all forms of energy. Effective use of energy can only be promoted if the ways in which electricity is used are known. In this dissertation the electrical energy requirements of the South African domestic sector are analyzed for the present situation and for the next few decades. A model is developed to represent the electrical load. The model has subsections representing the components of the national domestic electrical load, concentrating on electrical energy for domestic water heating, with responses to factors such as: * population growth, * urbanisation, * electrification, * energy efficiency of appliances, * consumer awareness of energy conservation. The model is to be used for scenario planning of the electrical grid. The results of this study will assist to ensure effective planning of the electrical grid of South Africa into the next century.

Includes bibliographical references.The effect of energy on inequality and poverty is not well understood and its role in growth-inequality-poverty nexus has not been adequately studied. A country's energy mix can playa significant role in economic growth and poverty alleviation. Policy authorities and donors increasingly lend support to modem energy provision, especially Rural Electrification (RE). This thesis investigates which energy types contribute to poverty alleviation in South Africa and through what mechanisms. Theory indicates that poverty alleviation comes by growth boosting and inequality reducing policies. As such, the investigation of the pro-poor effects of any policy or factor would naturally culminate in studying the effects on economic growth (or production) and income distribution. Theory suggests endogeneity on one hand between energy and GDP and on the other between GDP and inequality. This necessitates a system of equations rather than the traditional single equations approach. There are other (South Africa-specific) reasons why the inequality-development relationship and the role of energy should be investigated. First, South Africa has been under-researched due to lack of data. Recent data released by the Presidency of South Africa (AMPS Dataset) makes such analysis possible. Secondly, the Kuznets' inequalitydevelopment hypothesis can be tested with time series data rather than the cross-section analyses found in earlier literature. Third, energy's role in economic growth or production has been analysed with aggregate energy measures and aggregate GDP. This work argues that such an approach will mask energy type-specific and sector-specific details and undertakes a more disaggregated analysis. Fourth, the multiracial nature of South Africa requires sub-group decomposed inequality rather than national aggregates.

The objectives of this research, were to investigate the characteristics and develop a profile of the game and hunting industries of KwaZulu-Natal, and to undertake a comparison between the game and hunting industries in KwaZulu-Natal and the Eastern Cape. The comparative part of this study was completed using results obtained from a study done in 2002 in the Eastern Cape (van Niekerk, 2002). The main farming activities in KwaZulu-Natal are large livestock production and sugar cane production. In recent years, private landowners in KwaZulu-Natal have undergone a transition from livestock production to game ranching due to the problems faced and the cost implications of the HIV epidemic, stock theft, difficulties faced with changes in the labour laws and the increasing number of land claims against farmers. Although the game and hunting industries are relatively young industries in KwaZulu-Natal they contribute significantly to the economy of the province. Not only is greater conservation of the biodiversity more effective in game ranching but it is also proving to yield great economic returns. The increase in game ranching in recent years is namely due to the monetary value placed on wildlife, the increased value in ecotourism and its value as an earner of foreign exchange, less dependency on unskilled labour than that of livestock farming and lower rates of animal loss through theft compared to that of livestock farming. In KwaZulu-Natal game numbers indicate that impala have the greatest population amongst the respondents, followed by nyala, blesbok, common reedbuck, kudu and blue wildebeest, whilst other game species occur in smaller numbers. Respondents in KwaZulu-Natal indicate that nyala is the largest economic earner for them followed by buffalo, whereas in the Eastern Cape (2002), kudu and springbok provide the greatest income for the province. In KwaZulu-Natal income generated from hunting is second to that of live game sales compared to the Eastern Cape (2002) where hunting is the most important form of game utilisation in terms of income generated. At the time of this study, respondents in KwaZulu-Natal reported an income of R 15 382 397 generated from live sales and R 13 561 459 from hunting. These respondents also indicated that the total value of game utilised annually was in excess of R 30 million. Although game utilisation is occurring on a sustainable basis, there is room for greater utilisation of some game species which, if undertaken correctly, can increase the revenue for the province significantly and also contribute positively to further sustainability of the game populations. KwaZulu-Natal’s competitive advantage is derived from the fact that there is an abundance of game on the ranches, quality trophy animals are available, the number of game species available for hunting and quality of service rendered to hunters by the professional hunters and ranch owners. This study has clearly shown that there is a need for further investigation into the game and hunting industries in KwaZulu-Natal.

Full textAbstract:
Includes bibliography.A proposal to develop the Upper Tugela Location in KwaZulu, Natal, prompted this study. This study aims to investigate the means to enhance the availability of, and access to, affordable energy sources in the Upper Tugela Location. A further aim is to match appropriate energy sources with the socio-economic conditions prevailing there. The Upper Tugela Location is an ecologically sensitive area of the Upper Tugela catchment. Rural energy planning has been criticized for the development of energy-conversion technologies while there is insufficient understanding of energy procurement practices in rural subsistence economies in South Africa. Qualitative information gained from a questionnaire survey, informal group discussions and direct observations suggest that the inhabitants of the Upper Tugela Location are relatively poor. For this reason a basic rural energy needs approach, which attempts to address the needs of the poorest, has been adopted to provide a theoretical base for the study. Research has revealed the following. Wood is the dominant energy source in the Upper Tugela Location. It is estimated that the annual household consumption of fuelwood is 3000 kg which is below the average fuelwood consumption for a rural area in South Africa. This reflects that this resource is being depleted to the degree that the local inhabitants are supplementing their use of fuelwood with expensive commercial fuels such as coal and paraffin. Locally available wood is in short supply, particularly in densely populated areas of the Upper Tugela Location. Most people are buying fuelwood from Natal farmers living on the borders of the study area. This results in an economic leakage from the Upper Tugela Location and dependence on extralocally available sources of energy. There appear to be few attempts to establish woodlots at present in the Upper Tugela Location. Equitable access to local supplies of wood are curtailed. Renewable sources of energy such as thermal and photovoltaic solar energy, micro-hydro and wind generated power, and afforestation have been investigated as have non-renewable sources of energy such as grid electricity and commercial fuels. It is concluded that no single technical option adequately addresses the energy needs of the inhabitants of the Upper Tugela Location. Most of the renewable sources of energy, except wood, are too expensive for subsistence economies and can be unreliable as they are still at the developmental stage. It is recommended that electricity from the national grid should be made available to those who can afford it. The means to improving the distribution of commercial fuels in the Upper Tugela Location should be addressed. Woody biomass management and agroforestry programmes provide the best options for an energy strategy for the Upper Tugela Location as they are inexpensive, require little maintenance, are sustainable and reliable, and serve conservation requirements at the same time.

Thesis (MPhil)--Stellenbosch University, 2015.ENGLISH ABSTRACT: The South African Government developed the REIPPPP to ensure the implementation of Green Economy and job creation policies, while mitigating the current power crises with the short lead times of RE technologies. Current South African literature is ambiguous when discussing the legitimacy of the REIPPPP and the overall understanding of the programme and its associated outcomes in terms of job creation, are therefore, vague. A need therefore exists to unpack the quantitative job creation submissions of the REIPPPP and to carry out an investigation into the opportunities and challenges associated with meaningful job creation. Through a non-linear iterative exploratory design, hinging on the researcher’s position within industry, this empirical research comprises of two components. Firstly, a literature study informs the development of a meaningful job creation framework which is used to analyse the programme’s bid documentation and publicly available data. Secondly, mixed-methods are utilised to collect quantitative data from the DoE and qualitative data from job creation stakeholders. The result is an enriched understanding of the REIPPPP in terms of meaningful job creation, identifying trends, similarities and unexpected outcomes across methods. The study concludes that the programme does create meaningful jobs yet data is misaligned and currently unavailable to the public. Secondly, since job creation is a feature of South African Government development policy, a more robust emphasis is required in the REIPPPP weighting and auditing process, which includes further research of intended benefits and suggested improvements to align job creation data.
AFRIKAANSE OPSOMMING: Die Suid-Afrikaanse regering het die hernubare energie onafhanklike kragprodusent verkrygingsprogram ontwikkel om die voorsiening van die werksskeppingsbeleid en groen-ekonomiebelied te verseker. Huidige Suid-Afrikaanse letterkunde is dubbelsinnig wanneer die wettigheid van die program bespreek word. Die algehele begrip van die program en sy geassosieerde uitkoms is dus vaag.

Tweedens, word gemengde metodes gebruik om kwantitatiewe data van die departement van energie te versamel asook kwalitatiewe data van werkskeppingbelanghebbendes. Die resultaat is n meer verrykende verstandhouding van die hernubare energie onafhanklike kragprodusent verkrygingsprogram in terme van betekenisvolle werkskepping asook die identifisering van tendense en onverwagse uitkomste. Die studie kom tot die gevolgtrekking dat die program nie betekenisvolle werk skep nie en is tans onbeskikbaar vir die publiek.

Full textAbstract:
The Republic of South Africa’s energy economy is under immense pressure and the main energy utility, Eskom, cannot reliably generate sufficient electrical energy to meet its customer demand. Water security in South Africa is also under threat as the country is currently amidst a water crisis. The South African manufacturing industry is the sector consuming the largest portion of the total energy consumption and second largest portion of the total water consumption (excluding urban use) nationally. Water and energy efficiency improvement is becoming imperative for organisational success as well as national economic sustainability. This is due to the significant increase in the cost of both electrical energy and water in recent years, and the drop in the reserve energy margin below the minimum level required for sustainable operation of energy utilities. The research objective therefore was to develop a Lean-based water and energy efficiency improvement framework for the manufacturing industry to encourage and realise a reduced demand for energy and water in it. A literature review was conducted on the water and energy landscape in South Africa, Lean manufacturing principles and their positive natural influence on water and energy efficiency, and the Value Stream Mapping tool. The survey of water and energy wastes in the manufacturing industry yielded the creation of standardised water and energy waste categories for use in conjunction with the conventional Lean wastes, tools and techniques. The literature survey indicated that the implementation of Lean manufacturing techniques naturally leads to the improvement of energy and water intensity. The researcher hypothesised that there is even greater potential for water and energy savings if a Lean-based tool is developed to specifically focus on the improvement of energy and water efficiency. A framework for this tool was developed through the literature survey. The tool is based on the Value Stream Mapping tool. A practical experiment was then conducted to establish the effectiveness of the tool in the South African manufacturing industry. The experiment design included an outline of the forecasting and statistical validation techniques to ensure the integrity of data utilised for approving or disproving the set hypotheses. The results of the practical experiment yielded positive results, confirming the hypothesis that the implementation of the developed framework will lead to improved energy and water efficiency in the manufacturing industry. After an explanation of the experimental results, the study concluded with recommendations and conclusions based on the findings.

Full textAbstract:
Biofuels have been used as an energy source for heating and cooking since the beginning of time. However, recent changes in the demand for energy, and in particular, renewable energy, have spurred the growth of liquid biofuel industries in developed countries. Many developing countries, including South Africa have the potential to produce biofuels with benefits extending into the economic and social spheres. Despite government commitments and targets, the South African biodiesel and bio-ethanol industries have stalled in the starting blocks. This research aims to assess the reasons why.
South Africa does not have the climate to compete with Brazil in bio-ethanol production and the scope for bioethanol is limited by environmental factors. However our neighbours show significantly more promise in this area. Biodiesel production is more likely to be commercially viable due to the country’s ability to grow oil crops and the need for the by-products.
Despite the availability of land for cultivation of energy crops, the required technology and suitable infrastructure, progress has been slow. Uncertainty, high risk and misdirected government interventions have hampered investment in the sector and those involved in biofuel projects are very negative about the government’s ability to stimulate the industry. Consequently, they are looking towards importing feedstock material and exporting the biofuel. This will create a limited number of jobs, but will be energy and carbon negative, and will not aid rural development.
Currently there is no medium or large scale virgin oil to biofuel producer operating in the country and the start-up dates for projects are beyond 2013. The WVO biodiesel industry has grown rapidly in the last five years but is limited to small scale operators with limited benefit potential.
With the exception of Brazil, other world leaders in biofuels are facing heavy criticism and the mechanisms used to initially boost the industry have very limited application in South Africa. The benefits of biofuel production in South Africa are plentiful and align well with social need and development goals.Thesis (MBA)--North-West University, Potchefstroom Campus, 2013.

Thesis (MPhil)--Stellenbosch University, 2015.ENGLISH ABSTRACT: This thesis emerges from the transdisciplinary work of the Enkanini Research Centre Association. Since 2011 this Association has focused on incremental informal settlement upgrading using Enkanini, Stellenbosch as a case study. This thesis explores whether management techniques and operational practises of microfranchising can support the establishment of alternative service delivery configurations in the context of in situ informal settlement upgrading. Following a transdisciplinary and multiple-case study research methodology, the theoretical argument is presented that a synthesis of the strengths and vulnerabilities of contemporary innovations from the urban development field augmented by the principles and management techniques of microfranchising could strongly influence future in situ informal settlement upgrading. In exploring this argument two sub-questions are analysed in two free standing journal articles. The first article explores the potential synthesis of the fields of microfranchising and incremental urbanism, specifically alternative service delivery configurations in the context of in situ informal settlement upgrading. The literature on incrementalism and microfranchising originate from diametrically opposite ideological traditions, namely contemporary urban development and the management sciences. However it is argued that convergent patterns highlighted by points of coherence and convergence between the fields indicate that the proposed amalgamation has strengths potentially useful in addressing mutual weaknesses inherent to both perspectives. The intersection between these two distinct theories has potential to stitch together a new community fabric, deliver basic services, promote economic and social development and integrate the oppressed into the formal economy. Building on this theoretical synthesis the second article explores potential best practice microfranchising cases. Three microfranchising cases are reviewed, Unjani Clinics NPC, African Honey Bee and Nuru Energy. Each case presents specific within-case lessons and microfranchising techniques. Cross-cutting themes from all three cases highlight knowledge, that when bolstered by everyday urbanism thinking, could be instrumental in developing a microfranchising consolidating, operating and scaling model for the iShack and the continued testing of the proposed synthesis.
AFRIKAANSE OPSOMMING: Hierdie tesis het ontstaan uit die transdissiplinêre werk van die Enkanini Research Centre Association. Sedert 2011 het hierdie vereniging gefokus op die inkrementele opgradering van informele nedersettings, deur van Enkanini wat net buite Stellenbosch geleë is, as 'n gevallestudie gebruik te maak. Die studie ondersoek of die bestuurstegnieke en operasionele praktyke van die mikrofranchisebedryf die vestiging van alternatiewe diensleweringskonfigurasies in die konteks van in situ opgradering van informele nedersettings kan ondersteun. Na afloop van 'n transdissiplinêre en meervoudige gevallestudie navorsingsmetodologie word „n teoretiese argument gevoer dat die samevoeging van beide die sterk- en swakpunte van die huidige innovasies van die stedelike ontwikkelingsveld aangevul sal word deur die beginsels en tegnieke van die mikrofranchisebedryf. Hierdie tegnieke en praktyke het die vermoë om in die toekoms in situ opgradering van informele nedersettings sterk te beïnvloed. In die verkenning van hierdie argument word twee sub-vrae in twee vrystaande tydskrifartikels ontleed. Die eerste artikel ondersoek die potensiële samevoeging van die velde van die mikrofranchisebedryf en inkrementele stedelikheid, met spesifieke fokus op alternatiewe dienslewerings konfigurasies in die konteks van in situ opgradering van informele nedersettings. Alhoewel daar in die literatuur oor inkrementalisme beweer word dat die mikrofranchisebedryf afkomstig is van lynregte teenoorgestelde ideologiese tradisies, word daar aangevoer dat konvergente patrone uitgelig word deur punte van samehang. Ooreenkomste tussen die velde dui daarop dat die voorgestelde samesmelting sterkpunte het wat potensieel nuttig kan wees om wedersydse swakhede wat inherent aan beide perspektiewe is, aan te spreek. Die samesmelting van hierdie twee afsonderlike teorieë het die potensiaal om ‟n gemeenskap te bou, basiese dienste te lewer, ekonomiese en maatskaplike ontwikkeling te bevorder, asook om die onderdruktes in die formele ekonomie te integreer. Geskoei op die voorafgaande teoretiese samevoeging, ondersoek die tweede artikel die potensiële beste praktyke in die mikrofranchisebedryf. Drie mikrofranchisebedryf-gevalle word hersien: UnjaniKliniekeNPC, Afrika Heuning By en Nuru Energie. Elke geval bied spesifieke binne-geval lesse en tegnieke in die mikrofranchisebedryf. Deurlopende temas van al drie gevalle beklemtoon kennis, wat met die ondersteuning van alledaagse stedelike denke, instrumentele waarde vir die ontwikkeling van 'n mikrofranchisingkonsolidasie, bedryfstelsel en skaalmodel vir die iShack, asook die deurlopende toets van die voorgestelde samevoeging, kan inhou.

Full textAbstract:
In South Africa most of the municipal solid waste is currently removed and taken to land fill sites for engraving. A very small percentage of this is recycled due to lack of exploration of alternative means of further processing. In 2011 approximately 108 million tonnes of waste, mostly being general waste was generated in South Africa. Ninety eight (98) million tonnes of this waste was disposed of at landfill sites (The Department of Environmental Affairs [DEA], 2012). Environmental engineers are finding municipal solid waste management to be a challenge, similarly do the city planners and local administration. The main reason being the difficulty brought about by the complexity in composition of the waste material, no availability of waste minimization technologies and the scarcity of land for landfill sites and their environmental impact (Lal & Singh, 2012). Anyaegbunam (2013) recommend that there is a disposal technique that can convert most of the landfill waste at reduced amount of money to what is being paid on other disposal techniques nowadays, regardless of its form or composition and produce an excess of clean energy, and that technique is called Plasma Gasification which carries a high capability of being economically efficient. According to Young (2010), plasma arc Gasification is a high-temperature pyrolysis process whereby the organics of waste solids (carbon-based materials) are converted into syngas. The syngas can also be sent to gas turbines or reciprocating engines to produce electricity. Few of these plants exist in the world, however there is none in South Africa due to municipal budgetary constraints and lack of evidence for return on investment. Gasification can be described as a thermo-chemical process wherein carbonaceous or carbon-rich feed stocks, for instance tree trimmings or biomass, coal, and petro-coke are transformed into a complex gas containing hydrogen and carbon monoxide (and smaller quantities of carbon dioxide and other trace gases) under high pressure, oxygen exhausted, strong heat and/or steam environments (SRS Energy Solutions, 2016) The problem of electricity shortages continues to increase and communities are unable to cope with the continuous rising electricity bills. It is forecast that electricity demand will grow by approximately 85% and thereby reaching 31 700TWH (terawatt hours) in the year 2035. This growth rate is anticipated at an annual rate of 2.4% of which the economic and population growth will be the driving force, while on the other hand the daily increase of waste at landfill sites poses many problems with regards to the lifespan of the landfill in case green technological disposal processes are not introduced.

Since the publication of the White Paper on energy Policy of 1998, South Africa has taken off on a new trajectory of sustainability. The South African government have identified that the renewable energy sector will play a critical role in advancing and improving the energy sector. They envisage that the sector will contribute to the development of a green economy and the creation of meaningful employment for all South Africans. With the renewable energy sector of South Africa being dependent on skills, many of which are pertinent for the success of the sector, sufficient skilled workers are required to provide a service to the growing sector. Upon engaging with individuals employed in the sector and embarking on the research it became apparent that there was a lack of a talent management framework for the sector. Talent management represents a means for companies to develop and sustain talent pipelines thereby creating a competitive advantage. Globally executives across the employment spectrum admit that they have challenges in building a strong talent pipeline. The South African Renewable Energy Sector (SARES) is not exempt from this reality, where it has been well documented that South Africa is struggling with a skills shortage. This makes it difficult to grow and develop a fledgling sector. The purpose of this treatise was to evaluate the need for a talent management framework for the South African Renewable Energy Sector. To evaluate this, a literature review was performed on concepts relating to the development of a talent management framework specifically for the sector. These concepts or independent variables were, engineering skills, competence, knowledge worker, policies supporting RE development as well as training and development. The talent management framework relied on ring fencing the study around the knowledge worker, by correlating the definition of an engineer to that of a knowledge worker. The results show that despite the proclamation made by the South African government that South Africa is geared to supply the skills required for SARES. The research found a need for educational institutes to produce more knowledge workers. The results of this research study showed that despite the low positive correlation between the five independent variables, being, engineering skills, competence, knowledge worker, policies supporting RE development they would still provide those responsible for recruitment and talent management with a platform to be able to develop a working talent management strategy. There is a need for the development of a suitable talent management framework, which would allow the sector to manage elements of talent management such as recruitment and retention of knowledge workers. The proposed talent management framework can be used to assist in consolidating the present recruitment practises as well as being used to develop a talent management strategy for the sector.

Analysis of electricity consumption us in g load profiles of each sector ' s end-use electrical loads is essential for determining the appropriate supply technologies as well as the impact of demand side management and energy efficiency measures . A supply side study considers all existing and future power generation options required for expected electricity growth and system load characteristics. Energy model, TIMES, provides time-slices for adequate load profile representation TIMES is a Partial Dynamic Equilibrium Model as constraints are placed on the investment, usage and availability of technologies. All optimisations are for the least cost to the system. Demand and supply options are integrated into a single plan using the TIMES model and the supply expansion plan is changed when demand reduction targets are achieved using DSM and EE. The base case us in g a business-as-usual approach is compared with a low and medium impact DSM and EE scenario. Demand resources are estimated from the industrial, commercial and residential economic sectors. The scope of the plan is 22 years and there is full utilisation of all existing supply capacity with small amounts of decommissioning. Mothballed power stations are recommissioned initially. Peak-load plants are needed from 2007 and OCGT are selected using natural gas or LNG. Intermediate-load capacity is needed by 2011 using CCGT. Base-load capacity demands are met using new coal PF power stations in 2014. FBC stations using discard coal begin operation in 2016. The capacity expansion plan anticipates 2. 93GW of OCGT, 2.5 GW of CCGT, 7. 2GW of coal PF, 2. 8 GW of FBC plants and 2 GW of pump storage stations to be in use by 2020. Imported hydroelectric capacity of0.9 G W and PBMR capacity of3 GW is expected to be commissioned by 2024. Approximately 4 % less installed capacity is needed when a medium impact DSM and EE strategy is implemented. The marginal cost of energy gradually increases from 0. 06 R/kWh in 2002 to 0. 175 R/kWh in 2016 and to 0.325 R/kWh in 2024 as supply capacity is added. Compound load profiles from all national electricity usage provide an effective means whereby appropriate supply technologies are selected whilst incorporating load modifications due to DSM and EE.

The world agricultural industry, despite numerous supply and demand challenges, has to significantly increase its production capacity to satisfy the increased demand for food and successfully address the issues surrounding food security. Access to credit is however a key enabler in this regard, while a lack of it limits the adaptive capacity of agricultural producers. The financing needs of agricultural producers however vary and are influenced by the different production systems which have different investment, revenue and risk patterns. The sector is unique in that the risk and uncertainty in agriculture are increased by the nature of agricultural production systems, which is in many cases driven by unpredictable external factors such as adverse weather conditions. In addition agricultural production systems also function within the total food system which consists of a number of interrelated subsystems, each presenting agricultural producers with a unique set of risk factors that need to be taken into account. The development of new and innovative financing solutions for the sector therefore requires a thorough understanding of the multidimensional nature of agriculture and the unique characteristics of the sector. The purpose of this study was to contribute to the development of new and innovative financing solutions for the agricultural sector in South Africa.

Coupled with the issue of promoting energy efficiency in South Africa is the need to focus on the source of energy production. The country's excessive burning of coal resources has been linked to the global warming crisis.
To address this energy crisis, taxpayers can be encouraged to play an important role in moving the country towards a position of energy stability by conserving energy or decreasing their energy consumption, or contributing towards the research and development of energy-efficient processes as well as cleaner forms of energy.
This study analyses the energy-related tax incentives that are currently legislated and available to South African taxpayers and discusses the feasibility of taking advantage of these incentives. The study may provide guidance to taxpayers that have decided to invest in renewable energy sources and will discuss some of the advantages and perceived challenges facing the renewable energy industry.
This study also provides a worked example that illustrates a detailed calculation of the energy tax saving incentive set out in section 12L of the Income Tax Act, No. 58 of 1962.
A case study guides taxpayers though the practical process of applying for and calculating their energy-saving tax deduction. The case study may be used as a point of reference for taxpayers planning to implement the section 12L energy efficiency tax incentive for the first time and may highlight complexities and concerns they should consider.Mini Dissertation (MCom)--University of Pretoria, 2016.

It is commonly known and acknowledged in contemporary times that the burning of coal and other fossil fuels has caused environmental harm on a global scale, especially global warming caused by emissions of carbon dioxide and other gases. Nuclear energy does not cause emissions, but the risk of nuclear accidents is a deadly and serious one for communities close to nuclear power stations.8 Furthermore, humans have not yet found a completely safe method for disposal of nuclear waste.9 Florini and Sovacool write that global energy governance is currently on an unsustainable and conflict-prone path. There are issues of unreliable supply, brittle and vulnerable energy infrastructure, massive environmental degradation, and failure to deliver energy services.10 Udall goes so far as to say that 'energy is the original currency', and that mankind is at the beginning of a period of resource nationalism.11 Victor and Yueh endorse this view, saying that the decade between 2000 and 2010 has seen governments in all the large consumer nations of the world besieged by doubts about their energy security.12 The increasing demand for energy across the world has a number of consequences. Among these, the most challenging for governments is the association of energy generation with climate change, resulting from emission of greenhouse gases in the process of burning fossil-based fuels to generate electricity.13 Victor and Yueh describe the energy sector as one of the most exciting technological frontiers in the world, with many countries changing their expectation as to what the sector should deliver, due to climate change.14 Across the world, renewable energy sources are being recognised as the safest and most desirable energy sources, as they are largely free of emissions and are non-depletable.15 In South Africa the legislative framework explicitly promotes the development and use of renewable energy. In this dissertation it will be shown how municipalities in South Africa can play a valuable role in energy governance, which, it is posited, is a central element of their legislative responsibilities with regard to service delivery, upholding of the Bill of Rights, promoting a safe and healthy environment, promoting local economic development, and other issues.

The India decentralised model is similar to the South African model, with the exception that corporate finance is widely used in India and Project Finance in South Africa. Thus there are lessons to be learnt from each country, however no single country financing model was found to be suitable for South Africa. Accordingly, this paper therefore recommends that South Africa’s model be altered to incorporate project bonds. The use of these bonds in the current financial model will ensure that banks are able to lend to projects on short term basis; thus, managing their liquidity and their asset--liability effectively. Further, some institutional investors have shown an interest in funding projects at the construction stage, and the inclusion of project bonds would ensure that more of these investors play a role in financing projects.

DOCTOR OF PHILOSOPHY (PhD)
in the School of Law at the University of the WitwatersrandMany countries are under pressure to transition from fossil to renewable sources of energy. This pressure comes from multiple points including sustainable energy and climate change imperatives. The energy industry, especially electricity generation, is the main source of greenhouse gases, hence the significance of reductions in this industry. The purpose of this study was to conduct a legal analysis of the renewable energy law in the context of energy law generally in South Africa, to understand the regulatory function of law in promoting renewable energy. The study analysed government legal and policy positions, and the response by non-state actors to such policy positions and laws. Through a qualitative analysis of primary and secondary sources of law and public participation documents, the study found that; while South Africa is committed to renewable energy, its socio-economic, cultural, and environmental context superimposes other priorities that impede progress towards renewable energy. Several obstacles to renewable energy were identified, some internal to energy law and others external to it, coming from other areas such as environmental law, governance, economics, and behavioural sciences. Analysis at the convergence of environmental and energy law revealed misalignment and fragmentation as major obstacles to renewable energy. While barriers are common across the globe, countries cannot apply the same responses with the same results. Regulatory responses, beyond the traditional ‘command and control’ tools are context specific and tools that have worked, in other countries, may not be as effective in South Africa. Socio-economic dynamics determine the legal responses to the barriers to renewable energy or the efficacy of economic incentives to promote renewable energy. However, overall, law and regulation can, and must, play a crucial enabling role by removing barriers to renewable energy. Nevertheless, there are limits to the use law ‘as regulation.’ Renewables will not replace fossil sources yet; rather in the long-term, renewables should become a big part of the energy mix. Despite gaining price competitiveness, it is too early for renewables to displace conventional fossil sources in a context of entrenched structural and institutional obstacles. Concomitant technical, market, economic, and environmental and resource governance interventions are necessary to effectively promote an energy mix substantially composed of renewables. The study recommends that law should create an enabling regulatory environment for renewable energy. South Africa has not used law effectively enough to create this environment, thereby impeding the integration of renewable energy into its energy mix. Aligning energy and environmental law, among other incentives, can enhance this role of law. Legal reforms are necessary to remove the regulatory advantage afforded to conventional sources of electricity and level the playing field.

Full textAbstract:
M.Ing. (Engineering Management)In January 2008, South Africa experienced a power crisis which changed how South Africa viewed its primary energy sector. South Africa largely depends on coal to generate 77% of the country’s energy needs. Eskom is the main electricity producer and the largest in Africa. Coal is the third largest exporter earner after gold and platinum and the second largest contributor to the South African export market after platinum (Falcon and Prevost, 2012). This highlights the importance of coal to the South African energy sector and economy. According to Geologist Chris Hartnady, the estimated coal production peak is in 2020, a period where most Eskom power station and mines would reach their lifespan (Davie, 2010). There are increased concerns about the quality of coal supplied to Eskom and the preference of coal producers to export coal to international markets. This could possibly compromise the supply of domestic coal. Historically, Eskom was supplied with lower grade coal and higher grade coal was exported. The increased demand for lower quality coal in the Asian markets has been an aggravating factor for the South African government to secure the security of coal supply to Eskom (Sapa, 2012). In March 2013, the South African government declared coal a strategic resource. This implies that the State has the right to regulate and restrict the export of coal to international markets. The available research conducted, by consulting economic firms such as the mineral advisory firm XMP consultants; suggest that the declaration of coal as a strategic resource will impact negatively on the South African economy in some ways and also influence investment attraction into the country (Booyens, 2013). This research seeks to analyse the consequences of declaring coal a strategic resource in South Africa. The enormities in the research subject title, “An analysis of the consequences of declaring coal a strategic resource in South Africa”, makes it extremely difficult to cover all aspects involved in a minor dissertation and to substantially quantify the results in monetary terms due to the facet of dynamic factors involved...

M.Ing.In a country that ranks forty seventh on a list of fifty countries in a world competitive survey economic growth should be a high priority in South Africa. The main player in South Africa's energy industry took up the gauntlet and is moving to economic growth with the vision 'to provide the world's cheapest electricity for growth and prosperity." Competition was introduced among the electricity producers by a process called trading and brokering. Majuba power station, the most expensive electricity producer on the South African grid, was left out in the cold. Management of Majuba is challenged to derive resourceful strategies to ensure sustained profitability. These strategies will require a study into world trends to enable them to be more competitive. Crystal ball gazing is not needed to know that major restrictions on pollution of the atmosphere by industry will be curbed by stringent legislation. The current electrification programme in South Africa is bound to impact the shape of the daily load curve. Labour cost and the rate of inflation have been increasing and can be expected to keep on rising in the foreseeable future. It is important to know what macro effect these factors will have on the South African power industry. Majuba must be able to identify the changes lurking on the horizon and have contingency plans in place to meet these challenges. In this work different types of plant needed to meet the daily load demand are researched from literature. It is then compared to the types of plant installed in South Africa. This leads to the conclusion that the installed plant in South Africa is not sufficient to meet the daily demand effectively. A case study is done on Majuba Power Station that has been operating in a two shifting mode since December 1996. This means that the units is started every day to be on full load in time for morning peak and then shut down after evening peak. It is also shown that this mode of operation is proffitable for a relatively expensive power generator.
