Full textAbstract:
In recent years, proponents of 'green and clean fuel' have argued that the costs of overreliance on fossil fuels could be reduced through transition to biofuels such as bio-ethanol. Global biofuel discourses suggest that any transition to biofuel invariably results in significant benefits, including energy independence, job creation, development of agro-industrial centres at local level and high revenue generations for the state with minimum negative impacts on the environment. With many risks and costs associated with traditional 'dirty' fuels, it is likely that many countries, particularly African countries, will move towards the 'green and clean fuel' alternative. However, until recently research has arguably paid limited attention to the local livelihood impacts related to land acquisition for biofuel development or the policy frameworks required to maximise biofuel benefits. With regards to biofuel benefits, some recent studies suggest that the much bandied potential for greater tax revenue, lowered fuel costs and wealth distribution from biofuel production have all been perverted with relatively little payoff in wage labour opportunities in return (e.g. Richardson, 2010; Wilkinson and Herrera, 2010). Based on work done in Chisumbanje communal lands of Zimbabwe (Thondhlana, 2015), this policy brief highlights the local livelihood impacts of biofuel development and discusses policy implications of the findings. By highlighting the justifications of biofuel development at any cost by the state, the study sheds some light on the conflicts between state interests and local livelihood needs.

Full textAbstract:
Renewable energy is a current issue in the world as well as in Turkey. Turkey has developing policies in the renewable energy field. Although it is a beneficial mean of obtaining energy, there are barriers on renewable energy production. In order to develop renewable energies, those barriers have to be analyzed and suitable implementations should be developed to overcome them. In this thesis policy and implementation on the renewables are evaluated in general and specially for Turkey. The electricity market is one of the crucial factors of development of the renewable energy. The day-ahead market and renewable energy support mechanism in Turkey are investigated. Finally benefit calculations is carried out in order to compare benefits of renewable energy in market and support mechanisms by using real time price and production values of two renewable energy plantsa hydropower and a wind power plants. Further, outcomes of newly developed prediction project for wind power plants are evaluated in terms of market benefit.

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. Daar is n behoefte om die kwantitatiewe werkskeppingvoorleggings te analiseer en om ondersoek in te stel in die geleenthede en uitdagings wat geassosieer word met betekenisvolle werkskepping. Deur n nie- lineêre iteratiewe ondersoekende ontwerp, wat gebaseer is op die navorser se posisie in die industrie, bestaan hieride empiriese navorsing, uit twee komponente. Eerstens, lig n literatuurstudie die ontwikkeling van n betekenisvolle werkskeppingsraamwerk in, en word gebruik om die program se boddokumentasie en publieke data te analiseer. 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. Tweedens, aangesien werkskepping 'n kenmerk is van die Suid-Afrikaanse regering se ontwikkelingsbeleid, word 'n meer robuuste klem vereis op die hernubare energie onafhanklike kragprodusent verkrygingsprogram se ouditeringsproses en verdere navorsing van die beoogde voordele word voorgestel.

Full textAbstract:
A variety of energy models and tools have been used for an comprehensive analysis of the complex energy systems and the design of pathway to sustainable energy world. This thesis analyzes three interesting problems in the electricity sector by developing and using suitable energy models.
Chapter 2 investigates how to incorporate demand responsiveness for policy analysis in the electricity sector using a least-cost model. This study develops its own least-cost model which includes some characteristics for two important policies in the electricity sector, and suggests an iterative approach for incorporating the demand response to price change under new policy. Based on a case study, the state of Georgia, this chapter shows the effects of including demand response on the evaluation of policy. Chapter 3 is about new technology adoption pathways in the electric power system. In this chapter, by investigating the related status of policies and specifications of electric vehicles and wind power technologies in the U.S., several adoption pathways of the technologies in the U.S. eastern interconnection have been developed. This study develops four-serial models for the estimation of future economic and environmental impacts of the technologies' penetration. The results show that the total greenhouse gas emissions of the entire energy system do not substantially decrease even with a high level of electric vehicle adoption. The combination of two technologies, even more with appropriate policies, can notably decrease the total greenhouse gas emissions. Chapter 4 is a study about demand response programs, particularly optional time-based rates, for residential customers. This chapter analyzes the main reason that the participation of the current programs is low even though the programs have benefits. This study investigates two policy tools, a subsidy for flexible residential demand and a shared-savings mechanism based on consumption pattern changes, and examines the implementation of the tools and their potential to overcome the current inefficient operation.

Full textAbstract:
The economic boom in South Africa following the 1994 democratisation led to increased welfare of the citizens and their purchasing power. This further resulted in increase in electricity consumption. The electricity supply did not increase proportionally to the increase in electricity consumption leading to the 2008 shortage of electricity which nearly damaged the power generating circuit. The literature review has shown that electricity supply and consumption have a positive impact on economic growth. It further showed that employment enhances economic growth. Conversely, it showed that power outages negatively affect economic growth. The research serves to investigate the relationship between electricity supply and economic growth in South Africa and to examine the impact of power outages on economic growth. It also seeks to find the appropriate structure for electricity supply industry that will lead to increase in economic growth. The autoregressive distributed lag (ARDL) bounds approach was used to find the relationship between economic growth, electricity supply, power outages and employment using quarterly data from 2000 to 2012. The ARDL technique was chosen over the conventional models such as Johansen technique for the research because it uses a single reduced form of equation to examine the long run relationship of the variables as opposed to the conventional Johansen test that employs a system of equations. The ARDL technique is also suitable to use to test co-integration when a small sample data is used and does not require the underlying variables to be integrated of similar order. The Vector Error Correction Model (VECM) Granger causality was also employed in the study to establish the causality between economic growth and electricity supply. It was chosen for its ability to develop longer term forecasting, when dealing with an unconstrained model. The results from the ARDL bounds test showed that there is a long run relationship between economic growth, electricity supply, power outages and employment. Based on the causality tests, the findings showed a unidirectional causality flowing from electricity supply to economic growth. This implies that electricity supply affect economic growth in South Africa. The results further showed no causality flowing from economic growth to electricity supply which indicates that when economic growth is booming fewer funds are used for improvement of the electricity generation. Lastly, the results showed that power outages negatively affect economic growth in the long run. To sum up, electricity supply is an important factor for economic growth in South Africa. It is therefore necessary that South Africa must put in place measures aimed at stimulating electricity supply. One of the measures aimed at increasing output of electricity is to unbundle the electricity sector. This process involves allowing entry of the Independent Power Producers (IPPs), Independent System Operator (ISO) and Regional Electricity Distributors (REDs). This will lead to increased supply of electricity and competitively lower prices of electricity. The study further recommends that renewable energy sources should be used to produce electricity instead of coal and nuclear fuels as they failed to produce enough electricity for the nation.

Karlsson, Sundqvist Therese, and Karin Källmar. "Integration of Environmental Aspects in Product Development Process and Ship Design : a LEAP towards environmental awareness at Kockums AB." Thesis, Linköpings universitet, Industriell Produktion, 2012. http://urn.kb.se/resolve?urn=urn:nbn:se:liu:diva-80969.
Full textAbstract:
The Swedish company Kockums AB, at the forefront within maritime and naval technology, is in need of a tool, document, and/or method to include environmental aspects in their product development process. This is mainly because of additional requirements put on Kockums AB from their main customer. Ship recycling is the major issue that has to be addressed and included in Kockums AB’sworking procedures. Moreover, ship recycling is a pressing issue to handle due to horrible conditions in South Asian countries, where most ship dismantling is taking place. For these reasons, the objective of this M.Sc. thesis was to integrate environmental aspects in the product development process at Kockums AB by designing and proposing a way of implementing a tool, document, and/or method. Environmental product requirements that Kockums AB is demanded to fulfill mainly derives from customers, classification societies, laws and legislations, and themselves. The Hong Kong Convention has been adapted, in 2009, but is yet to enter into force. Ship recycling is covered by the convention,and an ‘Inventory of Hazardous Materials’ has to be provided from the ship builder, and hence this is the main aspect for Kockums AB to consider. Naval ships are, however, excluded from the Hong Kong Convention. Kockums AB does not have a routine on how to handle environmental requirements nor are environmental aspects included in their product development process. Consequently, Kockums AB’senvironmental ambition should not be put too high and rather aim at follow laws. In an empiricalstudy, regarding environmental aspects at Kockums AB, difficulties were identified. Lack of environmental knowledge, communication problems, and misunderstandings regarding the ambiguous term environment showed to be most notable. The three most prominent success factors for asuccessful integration of ecodesign, from the conducted literature review and empirical findings, are education for employees, existence of an environmental champion, and top management support. A Long-term Environmental Action Plan (LEAP), which took the success factors into account and contains 18 Actions, was developed for Kockums AB, and is the ultimate result of this research. The LEAP was developed in accordance with ISO 14006, a new standard for incorporation of ecodesign in Environmental Management Systems, with the aim of reducing adverse environmental impactsthroughout a product’s lifecycle. Moreover, the proposed way of implementing the LEAP was based on a ”Plan, Do, Check, Act” methodology from Product-Oriented Environmental Management Systems (POEMS). POEMS focus on a product’s environmental efficiency throughout its lifecycle, by a systematic integration of ecodesign in the company’s strategies and practices, and hence continual improvements. This way of implementation should be familiar to Kockums AB because the company is certified according to ISO 14001, where continual improvement of environmental performance is a key factor. The proposed LEAP includes tools, documents, and methods that are to be used in daily work and product development at Kockums AB. It is a step towards environmentally conscious design and enhanced environmental knowledge at Kockums AB. Additionally, as a result of the LEAP, the expectation is that environmental conscious mindsets of employees arise.

Full textAbstract:
The key focus of this dissertation is to produce research upon energy and climate change issues in the UK in a policy relevant and theoretically sound way. It aims to inform industry and policy makers to allow politically palatable, successful and effective future energy and climate change policy to be developed by identifying the preferences of the public for different policy scenarios. The Choice Experiment method was employed throughout this dissertation as the consistent methodological approach allowed for greater comparability of the results in addition to allowing the method’s robustness and reliability to be tested. The first part of this research (Chapter 3) is concerned with investigating attitudes and willingness to pay for future generation portfolio of Scotland by investigating household preferences for various energy generating options, such as wind, nuclear and biomass compared to the current generation mix. We identified the Scottish public have positive and significant preference towards wind and nuclear power over the current energy mix. We also found heterogeneity in public preferences depending on where respondents live which is reflected in their preferences towards specific attributes. Presence of non-compensatory behaviour in our sample is another element which was investigated in this part. Chapters 4 and 5 contain analyses of two independent choice experiments which were run in parallel. They take a UK-wide approach and investigate public preferences for more general areas of future energy and climate change policy, such as: carbon reduction targets, focus on energy efficiency improvements and attitudes to micro-generation versus large scale renewable generation. In addition the preferences for adaptation to and mitigation of climate change are investigated. Micro-generation is not often considered by energy companies when it comes to planning their generation strategies and was therefore of particular relevance to this research. As such Chapter 6 identifies the importance that the public places on this particular energy option and how it compares with their preferences towards other key energy and climate change policies of the UK. To analyse reliability of the results and to contribute to the theoretical field of stated preference valuation, each of the experiments contained two overlapping attributes, i.e. increase in level of micro-generation and an increase in total cost to a household, comparison of which was also carried out in Chapter 6. Finally in Chapter 7 the results found in the sections described above are discussed with reference to the policy background in the UK and Scotland. Also issues with the research and areas for further study are identified.

University of Stellenbosch Business SchoolENGLISH ABSTRACT: This study examined the relationship between economic structure and energy intensity in selected developed and developing countries of the world. A methodological and systematic approach was adopted to select the thirty-one countries explored in the study. Therefore, to answer the research questions posed in the study, the Granger Causality Technique and the Augmented Dickey-Fuller (ADF) method were used. This study discovered that the variables examined in the study showed variations. The variations emerged because of differences in methodologies and analytical frameworks adopted. Errorcorrection models were estimated and used to test for the direction of Granger causality. In the model, a high R2 was observed among the six variables (i.e. energy efficiency, per capita income, manufacturing, average energy prices, energy imports, technological developments), which invariably account for 60.8 percent of the variance in the energy intensity. Based on this, the unidirectional Granger causality runs from efficiency, per capita income and manufacturing to energy intensity. Hence, the price effects are relatively less significant in the causal chain. The result is at variance with the hypothesis that the structure of the economy does not determine its energy intensity. Nevertheless, a unidirectional Granger causality running from economic structure to energy intensity indicates that improvement in the economic structure would encourage a decline in energy intensity.

Full textAbstract:
Thesis (MPhil)--Stellenbosch University, 2010.ENGLISH ABSTRACT: Low-income households in the Western Cape primarily use small electrical kettles to heat water for bathing and cleaning. This energy usage pattern is problematic in that; • It is based on unsustainable energy sources that cause environmental degradation, • Electricity is becoming more expensive in South Africa which strains the limited income of poorer households and • The national utility, Eskom, is struggling to meet the demand for electricity. If energy-intensive development paths are followed these problems will escalate further. Solar water heating offers a synergic (Max-Neef 1991), if partial, solution for the situation. By decoupling hot water usage from increased electricity usage, solar water heaters (SWHs) can reduce electricity demand and thus environmental degradation. The large quantities of hot water (relative to electrical kettles) that they provide also fulfil a developmental service by improving quality of life and personal health. The manufacturing and installation of solar water heaters could serve as a further catalyst for development by providing opportunities for economic development. Unfortunately the high capital cost of SWHs remains a barrier to the rollout of the technology in lower income groups. The objective of this thesis is to contribute to the elimination of this barrier through providing insight into; the hot water requirements of low-income households, the potential electricity and carbon emission savings that solar water heaters present, and the cost drivers and job creation potential of the solar water heating value chain. The research hypothesis is that: Solar water heaters (SWHs) are a potential synergic satisfier to achieve sustainable development in low income communities by providing an improved energy service, reducing environmental degradation and creating employment opportunities. The high price of the technology makes intervention in the form of subsidies and/or regulation from the appropriate level(s) of government critical for the realisation of this potential. The methodology used to test the hypothesis is quantitative and qualitative in nature with data obtained through a survey of 90 low-income households in Stellenbosch, a behavioural study of two households wherein solar water heaters were installed and a value chain analysis of the SWH industry in the Western Cape. The key findings of the research include that, SWHs offer a real improvement in quality of life for low-income households and that they reduce electricity consumption relative to a level of development. The key barrier to cost reductions in the solar water heating industry is found to be the small size of the industry which leads to an inability to source material, especially copper, at competitive prices. It is proposed that government sponsored rollout programs could alleviate this barrier, leading to the development of a robust industry. Job creation potential is found to be relatively small but a suggested rollout programme for SWHs in the Western Cape shows that the benefits of the technology can be realised and several thousand jobs created in a fiscally prudent manner. The thesis is focuses on households from LSM categories 5-8 in the Western Cape Province. Stellenbosch Municipality is used as a specific case study area.
AFRIKAANSE OPSOMMING: Lae-inkomste huishoudings in die Wes-Kaap gebruik klein elektriese ketels as hul primêre water verhittingstoestel vir bad en skoonmaak aktiwiteite. Hierdie energie verbruik patroon is problematies in dat; • Dit gebaseer is op onvolhoubare energie bronne wat skadelik is vir die omgewing, • Elektrisiteit duurder word in suid afrika, en sodoende druk plaas op die beperkete inkomste van armer huishoudings en • Die nasionale elektrisiteitsdiensverskaffer, eskom, sukkel om te voldoen aan die vraag vir elektrisiteit. As energie-intensiewe ontwikkelings paaie gevolg word sal hierdie probleme verder vererger. Son water verhitting bied 'n sinergiese (Max-Neef 1991), dog gedeeltelike, oplossing vir die situasie. Deur warm water verbruik te ontkoppel van toenemende elektrisiteitsverbruik kan son water verwarmers (SWVs) die vraag na elektrisiteit en dus omgewingskade verminder. Die groot hoeveelhede warm water (relatief tot 'n elektriese ketel) wat die toestelle voorsien vervul ook 'n ontwikkelingsdiens deur verbeterde lewenskwaliteit en persoonlike gesondheid mee te bring. Die vervaardiging en installeering van SWVs kan dien as 'n verdere katalisator vir ontwikkeling deur geleenthede vir ekonomiese ontwikkeling te skep. Ongelukkig bly die hoë kapitaal koste van SWVs 'n struikelblok tot die verspreiding van die tegnologie in lae inkomste groepe. Die doelwit van hierdie tesis is om by te dra tot die verwydering van hierdie struikelblok deur insig te gee oor; die warm water benodigheid in lae-inkomste huishoudings, die potensiële elektrisiteit-en koolstofbesparings wat SWVs inhou, en die koste drywers en werkskepping potensiaal van die sonwaterverwarmer waarde ketting. Die navorsingshipotese is dat: Son water verwarmers 'n potensiële sinergiese bevrediger is vir die bereik van volhoubare ontwikkeling in lae-inkomse gemeenskappe deurdat dit 'n verbeterde energie diens voorsien, omgewingskade verminder en werksgeleenthede skep. Die hoë prys van die tegnologie verorsaak dat ingryping deur die toepaslike vlak(ke) van regering, deur middel van subsidies en/of regulasie, benodig word om die potensiaal daarvan te verwesenlik. Die metodologie wat gebruik word om die hipotese te toets is kwantitatief en kwalitatief van aard met data wat verkry word deur 'n opname onder 90 lae-inkomste huishoudings in Stellenbosch, 'n gedragstudie van twee huishoudings waarin SWVs geinstalleer is en 'n waardekettinganalise van die SWV industrie in die Wes-Kaap. Die sleutel gevolgtrekkings van die navorsing sluit in dat, sonwaterverwarmers 'n werklike verbetering in die kwaliteit van lewe van lae-inkomste huishoudings meebring en dat hulle elektrisiteitsverbruik relatief tot 'n vlak van ontwikkeling verminder. Die hoof struikelblok tot koste verminderings in die SWV industrie word gevind in die klein grootte van die industrie wat lei tot die onvermoë om materiaal, veral koper, teen kompeterende pryse aan te koop. Dit word voorgestel dat regeringsondersteunde verspreidingsprogramme hierdie struikelblok kan verwyder en dat dit sal lei tot die ontwikkeling van 'n gesonde industrie. Werkskeppingspotensiaal word gevind om relatief klein te wees, maar 'n voorgestelde verspreidings program vir SWVs in die Wes-Kaap wys dat die voordele van SWVs gerealiseer kan word en etlike duisend werksgeleenthede geskep kan word op 'n finansieel verantwoordelike wyse. Die tesis fokus op huishoudings in die LSM kategorieë 5-8 in die Wes-Kaap provinsie. Stellenbosch munisipaliteit word gebruik as n spesifieke gevallestudie area.

Esse trabalho mostra através de gráficos, tabelas, exemplos e análises, que a origem do fenômeno do aquecimento global (uso intensivo de energia) e o déficit social global é o incentivo para a demanda de produto e serviços que, de fato, não são necessários para uma vida digna e satisfatória da humanidade (consumismo). É obsen/ado que os benefícios desses produtos e serviços vão para uma parte mais privilegiada da população mundial, aumentando cada vez mais o abismo que separa a população mais favorecida da grande maioria das pessoas pobres e que, muitas vezes, não fazem uso de o mínimo necessário par prover sua subsistência. Esse trabalho tem a intenção de estimular o debate com vista a uma nova sociedade e para mostrar que um novo e simples estilo de vida deve ser considerado para resolver o problema do aquecimento global, as diferenças sociais e os sérios problemas de exaustão de recursos naturais da Terra.This work shows by means of graphs, tables, examples and analyses, that the origin of the phenomenon of the global warming (intensive energy use), and the global social deficit, is the incentive for the demand of products and services that, in fact, are not necessary to a dignity and worthy life of the humanity (consumerism). It is observed that the benefits for these products and services, go to a lowermost part of the world-wide population, widening each time more the abyss that separates the supplied populations of the great majority of the poor persons and that, in not rare times, do not make use of the minimum for the proper survival. In this direction, this work has the intention to stimulate a debate aiming a new society and to show that a new and a simple life style has to be consider to solve the global warming problem and the social inequalities and moreover, the serious problem of the exhaustion of the earth natural resource.

Resumo: Esta tese faz uma análise sobre a eletrificação rural para as comunidades isoladas do Brasil, mais especificamente para aquelas situadas distantes dos grandes centros consumidores, localizadas na região Norte e extremos da região Centro-Oeste do país. Analisou-se o atual programa vigente para a eletrificação rural no país contemplando as comunidades isoladas, qual seja o programa ?Luz para Todos?, verificando que este ainda possui limitações institucionais, metodológicas e financeiras para uma efetiva universalização do atendimento. Neste cenário, propôs-se a viabilização de uma política específica para a eletrificação das comunidades isoladas, com a criação inicial de um banco de dados e um planejamento por etapas, o qual inclui elementos de um Planejamento Integrado de Recursos, especificamente quanto à programação do processo de eletrificação, ao gerenciamento pelo lado da demanda (GLD) e à análise de custos completa ou multiobjetiva, para a definição da melhor opção para a geração distribuída de energia. O planejamento proposto inclui também elementos de um modelo de desenvolvimento endógeno, especificamente quanto aos investimentos em cadeia para a infra-estrutura, aos investimentos em capital humano local e à formação de redes para o mesmo fim.
Abstract: This paper analyzes the electrification process used for the isolated communities in rural Brazil, more specifically those farther from the great consuming centers, located in the country's Northern region and the extremities of the Mid-Western region. The current program for the agricultural electrification, the "Energy for All", was analyzed taking into consideration these isolated communities. This analysis showed that this program still has institutional, methodological, and financial limitations, which prevent it from achieving a broader and more effective service. With those issues in mind a proposal with specific policies geared towards the isolated communities was developed. The proposal included the creation of a data base and a ?stages' plan, which includes elements of an Integrated Planning Resources (especially when it comes to the distribution and implementation of energy), a Demand Side Management (DSM), and a complete or multi objective analysis of costs, which would help define the best option for the distribution and generation of energy. The considered proposal also includes elements of an endogenous model of development, more specifically the chain of investments for the infrastructure, investments in local human capital and the development of networks

CAPESEste trabalho apresenta o desenvolvimento de um estudo técnico social para definir as diretrizes que garantam a sustentabilidade de uma minirrede baseada em sistemas solares fotovoltaicos, localizados nas Zonas Não Interconectadas (ZNI) da Colômbia. A literatura da pesquisa está baseada na importância da energia elétrica e das construções sustentáveis para o homem e nos princípios de energia solar e de minirredes baseadas em sistemas solares fotovoltaicos. Após este levantamento, aplicou-se o método de pesquisa documental para contextualizar o leitor com os aspectos mais importantes sobre a Colômbia e sua realidade hoje. A partir destes aspectos foi possível concentrar a pesquisa em uma região, selecionada a partir de critérios de recurso solar disponível, economia, segurança, saúde e educação. Uma vez escolhida a região, foi feita uma pesquisa de campo em que foram entrevistados os agentes que podem influenciar no funcionamento de uma minirrede. Também foram observados os aspectos técnicos relacionados com as construções e a eficiência energética desta região, constatando que a mesma já contou, em alguma ocasião, com sistemas solares fotovoltaicos, mas estes foram vendidos pela própria comunidade por não encontrarem utilidade nenhuma neles. A partir das respostas encontradas nas entrevistas foi feita uma proposta de gestão da minirrede baseada em sistemas solares fotovoltaicos. Concluiu-se que é primordial que os agentes técnicos e administrativos do sistema como um todo tenham contato contínuo com o usuário para entender as suas necessidades e conseguir satisfazê-las com a instalação da minirrede. Também se observou que é importante criar no usuário um sentido de posse pela minirrede, identificando os benefícios educativos, de saúde e econômicos que esta nova tecnologia traz para ele. Este estudo abre as portas para novas pesquisas de avaliação e descrição das diretrizes propostas.
This research presents the development of a social-technical study to define guidelines to ensure the sustainability of a mini-grid based on solar photovoltaic systems located in Non Interconnected Areas (NIA) of Colombia. The literature of this research is based on the importance of energy and sustainable buildings to people, the principles of solar PV, and mini-grid based on solar photovoltaic systems. After this firt part, was applied the method of documentary research to contextualize the reader with the main relevant aspects of Colombia related to the research. From these aspects, it was possible to focus the research to a region, which was chosen by criterias such as: solar resource, economy, security, health and education. When the area was chosen, it was made a field survey. In this survey the agents that influence the operation of a mini network were interviwed. Also, it was observed the technical aspects of buildings, and the energy efficiency in this region. As a result it was observed that in the past there were PV solar systems, but these were sold by the community because they did not find them useful. From the interview answers, it was made a proposal about the management of the mini-grid based on solar photovoltaic systems. In conclusion, it is essential that the technical and administrative agents that make part of this system have continuous contact with the user to understand their needs and satisfy them with the installation of mini-grid. It is also important to create a sense of belonging from the user to the mini-grid, identifying the benefits, educational, health and economic that this new technology brings to him. This study opens the door to new research about evaluations and descriptions about the proposed guidelines.

Full textAbstract:
This thesis contributes to our knowledge on the emergence of environmental entrepreneurs. The study is guided by the research question, “how do UK environmental entrepreneurs start to form their distinctive environmental entrepreneurial thinking” and analyses the development of the environmental entrepreneurial mindset in the UK, through a theory of practice perspective. Based on a three-stage data collection process (preliminary focus group, semi-structured interviews and life stories), the study (1) conceptualises the construction of the environmental entrepreneurial mindset, (2) investigates the experiences of constraints for practice and (3) analyses differences in habitus and constraints on the basis of the sampling dimensions, type (social environmental and commercial) and gender (male and female). The study was undertaken under a social constructivist perspective and follows the naturalistic paradigm (Guba, 1978). The rigour (or trustworthiness) of the qualitative approach has been established according to perspectives by Mason (2001) and Guba and Lincoln (1985). The empirical basis of the study is comprised of a three stage design of discursive interviews, involving overlapping collective (focus group) and individual (life stories, in-depth interviews) data collection techniques, with a partly gathering structure (through semi-structured questions). A preliminary focus group identified key themes relevant to the study’s objectives and the concepts of the theory of practice (field, capital, and habitus). Three life stories refined the themes and analysed them within the context of entrepreneurs’ lives. The two stages enabled the development of questions targeting themes for the in-depth interviews and the cross case content analysis. For sampling purposes, the Maximum Variation Sampling (MVS) strategy was employed, which enabled identification and analysis of common and divergent themes (Miller & Crabtree, 1999) and by over-coming the limitations of the sample size, it provided a conditional representativeness. The findings show that environmental entrepreneurs accumulate divergent forms of cultural, social and economic capital, which shapes their entrepreneurial and environmental mindsets, triggering the creation of a disposition (habitus) towards setting up an environmental enterprise. Studying the formation of the environmental entrepreneurial mindset addresses a relevant knowledge gap and offers theoretical and methodological contributions. It also confers implications for practice, with a particular reference to entrepreneurial education and policymaking.

CapesOs indicadores energéticos são instrumentos de apoio a processos decisórios, sobre energia, e com a crescente discussão sobre desenvolvimento sustentável estes instrumentos passaram a incorporar informações socioambientais, além dos tradicionais fatores econômicos. Sendo assim, na busca pelo desenvolvimento sustentável, torna-se relevante conhecer quais são as contribuições e limitações destes instrumentos. Com este fim, o objetivo geral é analisar as contribuições e limitações dos indicadores energéticos como instrumentos de apoio ao desenvolvimento sustentável. Esta pesquisa é classificada como descritiva, utilizando levantamento bibliográfico e documental. Como resultado da análise documental foram selecionados 55 indicadores energéticos para o desenvolvimento sustentável (Energy Indicator Sustainable Development – EISD), sendo estes identificados a partir das instituições International Atomic Energy Agency (IAEA), Helio International e World Energy Council (WEC), dentre 19 instituições ligadas à pesquisa sobre energia identificadas na pesquisa. Durante a análise, percebeu-se que a maioria dos indicadores selecionados, 19 EISDs (34,54%), se concentra na dimensão econômica, seguidos de 10 EISDs (18,18%) na dimensão ambiental, 9 EISDs (16,36%) na dimensão social, 7 EISDs (12,45%) são classificados em resiliência, 4 EISDs (7,27%) em governança, 3 EISDs (5,45%) em vulnerabilidade e 3 EISDs (5,45%) em política. Apesar da inclusão de indicadores ligados a outras dimensões, além da econômica, a qualidade da informação gerada pelos indicadores surge como uma limitação destes, pois, identificou-se que, em casos recorrentes, as informações geradas pelos EISDs podem ser interpretadas tanto de forma a favorecer o desenvolvimento sustentável quanto a levar a ações opostas a este objetivo. Ainda, foram identificados EISDs cujos componentes não foram especificados, o que pode possibilitar a geração de informações afastadas do cenário real, caso sejam utilizados componentes que não possuem relação com o EISD, ou mesmo a não utilização de componentes relevantes. Ainda assim, apesar das limitações, a existência de conjuntos de EISDs para auxiliar os tomadores de decisão é um fato que contribui na busca por desenvolvimento sustentável, e que deve ser aprimorado, pois a disponibilidade de informações envolvendo questões socioambientais, como emissão de poluentes atmosféricos, de solo e de água, resultantes de fontes energética, possibilita identificar quais fontes são mais, ou menos, prejudiciais ao desenvolvimento sustentável. Contudo, a dificuldade na coleta de dados, na identificação dos componentes para o cálculo de cada indicador e mesmo na interpretação deste, como destacado, pode não só deixar de contribuir com o desenvolvimento sustentável, como pode protelar a tomada de decisões corretivas ou preventivas.
Energy indicators are tools to support decision-making on energy. The growing debate on sustainable development, contributed to the energy indicators began to incorporate, besides the traditional economic, social and environmental information. Therefore, taking sustainable development into account, it is important to know contributions and limitations of these tools. The overall goal of this study is to analyze the contributions and limitations of the energy indicators as assets to support sustainable development.This study can be classified as descriptive because it relies on bibliographical and documental material. As a result of documental analysis, 55 energy indicators for sustainable development (EISD) were selected. The selection took place by identification of those indicators through the institutions International Atomic Energy Agency (IAEA), Helio International and World Energy Council (WEC), among 19 institutions involved in research on energy identified in the survey. The study stresses that most of the selected indicators focuses on the economic dimension, 19 EISDs (34.54%), followed by 10 EISDs (18.18%) focused on the environmental dimension, 9 EISDs (16.36%) focused on the social issues, 7 EISDs (12.45%) are classified as resilience, 4 EISDs (7.27%) is about governance, 3 EISDs (5.45%) focused on vulnerability and 3 EISDs (5.45%) is about policy. Despite the inclusion of indicators associated with other dimensions than economy, information provided by those indicators emerges as their own limitation. Because, recently, indicators’ information were used to promote sustainable development as well as the opposite. Additionally, the study identified EISDs whose components were not specified. They may enable generation of information far from the real scenario, if components dissociated EISD would be taking into consideration or even the non-consideration of relevant components. Despite limitations, EISDs assisting decision-makers contributes to the pursuit of sustainable development. But they may be improved through information about environmental issues, such as emission of atmospheric pollutants, soil and water, resulting from energy sources, helps identifying which sources are more or less harmful for sustainable development. However, difficulty in collecting data, identifying the components for calculation of each indicator and even interpretation of this, as analyzed, may not only fail to contribute to sustainable development, as can delay taking corrective or preventive decisions.

Resumo: O atual estágio de desenvolvimento da humanidade apresenta-se cada vez mais agressivo ao ambiente e ao homem. O crescimento populacional aumenta cada vez mais o impacto das atividades produtivas e das edificações sobre o meio. Por esse motivo é importante que o desenvolvimento seja sustentável. Assim, foi realizada uma pesquisa por meio de questionários pré-testados, para verificar como os engenheiros civis e arquitetos estão preparados para reduzir o impacto das edificações sobre o ambiente e como podem ser melhor informados sobre o assunto. O resultado mostra que a maioria dos profissionais, que responderam ao questionário, têm pouco conhecimento sobre o conceito de desenvolvimento sustentável, reconhecem os impactos das edificações sobre o ambiente, acreditam que a qualidade seja o item mais importante para a construção civil, e têm interesse em conhecer e aplicar mais os conceitos que diminuam o impacto das construções sobre o meio
Abstract: The present human development has been proven wrong by its aggressive means on the environment and to the society. The global population growth, the industrialization and the edifications grown too, to meet the demand, interfering directly in the environment. It¿s important the application of a sustainable development in the civil construction. To identify how the professionals of civil construction are prepared to reduce the affects of edifications on the environment, a survey with pre-tested questionnaires was applied. In this questionnaire, the results show that the respondents do not know precisely what sustainable development means. The answer showed that a great deal of the professionals are worried about the constructions' impact on the environment, and have interest in knowing and getting to know more about the concepts and applying them to their professional life, and think: that quality is the most important thing to the civil construction

Full textAbstract:
Este trabalho objetiva contribuir com o planejamento da geração de energia elétrica por meio da utilização de geração fotovoltaica de forma distribuída, ou seja, instalada e em operação em paralelo junto com a rede de distribuição de energia elétrica. Utiliza-se uma abordagem hipotético-dedutiva, buscando hipóteses, na forma de questões orientadoras, que serão testadas por meio do tratamento dos dados coletados e sua posterior análise e interpretação. O método de procedimento é o estudo de caso, sendo escolhida a cidade de Curitiba e o restante dos municípios compreendendo sua Região Metropolitana. A partir da elaboração da revisão na literatura, visando constituir a fundamentação teórica desta pesquisa, é elaborado um breve inventário estatístico e do aspecto de geração de energia elétrica da cidade de Curitiba, no contexto do estado do Paraná. Os procedimentos metodológicos envolvem a simulação de cenários de inserção de geração fotovoltaica distribuída, considerando diferentes níveis de penetração, e seus efeitos sobre curvas de carga reais para a cidade de Curitiba. Foram selecionados 12 dias, considerados críticos, para a análise que contemplou a contribuição fotovoltaica em termos da redução do consumo de energia elétrica, redução de emissões de CO2 e, por fim, capacidade do sistema fotovoltaico em reduzir a demanda máxima do sistema elétrico. Constatou-se que o intervalo de capacidade instalada em energia solar fotovoltaica situa-se entre 40,80 MWp e 55,68 MWp, desconsiderando exceções, e remete a valores de máximo Fator Efetivo de Capacidade de Carga (FECC), para condição de irradiação máxima e irradiação típica, no inverno e verão. Dessa forma, este intervalo é considerado apropriado do ponto de vista do aumento da capacidade do sistema elétrico, devido à presença de geradores fotovoltaicos distribuídos. Além disso, o referido intervalo além de aumentar em mais de 50% a capacidade do sistema elétrico, acarreta em redução anual do consumo de energia elétrica entre 50,8 GWh e 69,4 GWh, além de evitar a emissão de 18.501 toneladas de CO2-eq a 25.251 toneladas de CO2-eq, sendo, portanto, um importante vetor para o aumento da oferta de energia elétrica, aumento da capacidade do sistema elétrico e, por fim, redução de emissões de Gases do Efeito Estufa, principalmente o CO2.This study aims to deepen knowledge in the item electricity generation planning through the use of distributed generation using solar photovoltaic energy, which means that photovoltaic systems are able to operate in parallel with the electricity distribution network. A hypothetical-deductive approach was developed, seeking hypotheses in the form of guiding questions, which will be tested by treatment of the collected data and their analysis and interpretation. The method of procedure is the case study, being applied to the Metropolitan Region of Curitiba. The literature review aims to be the theoretical basis of this research, therefore it mainly consists of a brief statistical and electrical energy inventory of the city of Curitiba in Paraná state. The methodological procedures involve the simulation of different scenarios for distributed PV generators by varying their Penetration Level, so that the effects on actual load curves for the region analyzed were quantified. 12 critical days were selected to the analysis that included the photovoltaic contribution in terms of reducing electrical energy consumption, reducing CO2 emissions and, finally, the capacity of the photovoltaic systems to reduce the maximum demand of the electrical system of the city. It was concluded that the most appropriate PV Penetration Level, in terms of power, regards with 40,80 MWp up to 55,68 MWp, disconsidering exceptions. This result leads to maximum values of Effective Load Carrying Capacity (ELCC), for maximum and typical solar radiation, during the seasons of winter and summer. In result, this proposed interval represents the better peak shaving capability of PV, because of its higher ELCC parameter. Furthermore, in addition to increase more than 50% in the capacity of the electrical system, there is an annual amount of energy generated about 50.8 GWh and 69.4 GWh, which represents 18,501 to 25,251 tons of CO2-eq avoided. For this reason, solar PV energy is an extremely important and feasible strategy to enhance the electricity generation, the capacity of the electrical system and to reduce greenhouse gases emission, especially CO2.

Les contraintes énergétiques de cette classe de réseau font appel à des topologies particulières et le réseau peut être perçu comme étant un ensemble de grappes de nœuds capteurs. Ceci ouvre la porte à des techniques avancées de communication de type MIMO. Dans un premier temps, les différents aspects caractérisant les réseaux de capteurs sans fil sont introduits. Puis, les efforts engagés pour optimiser la conservation de l'énergie dans ces réseaux sont résumés. Les concepts de base de systèmes MIMOs sont abordés dans le deuxième chapitre et l'exploration par voie numérique de différentes pistes de la technologie MIMO sont exposées. Nous nous intéressons à des techniques de diversité de polarisation dans le cadre de milieux de communication riches en diffuseurs. Par la suite, des méthodes de type beamforming sont proposées pour la localisation dans les réseaux de capteurs sans fil. Le nouvel algorithme de localisation est présenté et les performances sont évaluées. Nous identifions la configuration pour la communication inter-grappes qui permet pour les meilleurs compromis entre énergie et efficacité spectrale dans les réseaux de capteurs sans fil. Finalement, nous envisageons la technique de sélection de nœuds capteurs afin de réduire la consommation de l'énergie dans le réseau de capteur sans filThe aim of this work is to study from a signal processing point of view the use of MIMO (Multiple Input Multiple Output) communication systems for algorithms dedicated to wireless sensor networks. We investigate energy-constrained wireless sensor networks and we focus on cluster topology of the network. This topology permits for the use of MIMO communication system model. First, we review different aspects that characterize the wireless sensor network. Then, we introduce the existing strategies for energy conservation in the network. The basic concepts of MIMO systems are presented in the second chapter and numerical results are provided for evaluating the performances of MIMO techniques. Of particular interest, polarization diversity over rich scattering environment is studied. Thereafter, beamforming approach is proposed for the development of an original localization algorithm in wireless sensor network. The novel algorithm is described and performances are evaluated by simulation. We determine the optimal system configuration between a pair of clusters that permits for the highest capacity to energy ratio in the fourth chapter. The final chapter is devoted to sensor nodes selection in wireless sensor network. The aim of using such technique is to make energy conservation in the network

This thesis makes contributions to provide the microeconomic evidence on the effects of electricity provision and on the feasibility of electricity provision via renewable energy in developing countries. Three selected topics are presented.
First, we discuss how the impact of national electricity grid provision affects household welfare and individual labor activities in Vietnam. To overcome the endogeneity problem of infrastructure provision, the slope of the terrain is used as the instrumental variable. We present both first-difference regression and pooled regression results using household survey data and geographic datasets. The effect of electrification on female labor supply is negative, contrary to the evidence suggested in the previous literature.
Second, we measure willingness to pay for solar lanterns among the poor rural households in India using the Becker-DeGrook-Marschak method. We conduct field surveys to evaluate the effectiveness of providing a trial period and postponed payment scheme to promote sales. Results show that willingness to pay for the solar product among the consumers is low.
Lastly, we report patterns of awareness and interest in solar home systems (SHS) among the poor rural households in India. Results show that willingness to pay for SHS is low, even if the national subsidy is taken into account. Moreover, households that have experience using grid electricity have greater willingness to pay for SHS.

Full textAbstract:
The rising cost of energy coupled with an increasing awareness of Greenhouse Gas (GHG) emissions has led to a concerted effort to reduce fossil fuel Energy Use (EU) in all sectors. Sugarcane production in South Africa is dependent on fossil fuel to provide a source of energy for production. To remain commercially and environmentally sustainable, measures need to be taken to reduce EU and increase EU efficiencies of on-farm operations. The first step toward realising this is to identify and quantify energy inputs. Following on from this, total GHG emissions, also known as carbon footprint, can be estimated.
The primary objective of this research is to develop an energy calculator to estimate EU in sugarcane production in South Africa. The results generated by the calculator highlight areas of high energy intensity and low energy efficiencies at three different levels of detail. Based on these results, changes in management practices and technological improvements can be made to reduce EU and carbon footprint. Case studies were used to test the functionality of the calculator. Results from the case studies show that, in irrigated sugarcane production, the harvest and transport process together with irrigation account for a majority of the total on-farm EU. For one of the case studies, an estimated 20 % saving in the total on-farm EU was identified and can be achieved if appropriate technology is adopted in irrigation practices. Less significant energy savings were realised when in-field tractor operations were optimised for best tractor-implement matching.
It is envisaged that the energy calculator will help farmers minimise on-farm EU and subsequently reduce input costs and carbon footprint. It will also provide a valuable tool for researchers to benchmark and profile EU in sugarcane production in South Africa. Research focussed on the sustainable production of sugar, from the agricultural to milling phase is of high priority at present. The quantification of on-farm EU in sugarcane production will form a critical component of such research.M.Sc.Eng. University of KwaZulu-Natal, Pietermaritzburg 2014.

The essence of this dissertation is to enlighten the client on those strategic options available for a financially viable energy source and is also aimed at increasing the electricity share of the energy market, which is currently approximately 25%. This dissertation focuses on the industrial sector of the economy. Energy sources available to the Industrial sector, namely coal, diesel, illuminating paraffin, heavy fuel oil, liquefied petroleum gas and electricity, were selected for this specific study and compared in eight geographic areas. These inland areas include Pretoria-Witwatersrand- Vereeniging (PWV), Bloemfontein, Pietersburg and Nelspruit, and the coastal areas include Cape Town, Durban, Port Elizabeth and Richards Bay. As the energy cost is not the only factor influencing the total cost of using a particular energy source, the objective for this study was also to evaluate energy sources on an effective cost basis, taking account of energy price as well as indirect costs and utilization efficiencies. The typical industrial application of steam generation was selected and the costs related to using various energy sources in this application evaluated. This study also considers critical factors likely to be taken into account by consumers when choosing an energy source, or deciding on an energy conversion, which includes Demand Side Management (DSM). DSM refers to a process by which electric utilities especially Eskom, in collaboration with consumers achieve predictable and sustainable changes in electricity demand. These changes are affected through a permanent reduction in demand levels (Energy efficiency) as well as time related reduction in demand level (Load Management)Thesis (M.Com.)-University of Kwazulu-Natal, 2005.

A Dissertation submitted to the Faculty of Humanities University of the Witwatersrand, Johannesburg in fulfilment of the requirements for the degree of Doctor of Philosophy.
April 2017Sustainable development is one of the major discourses of the twenty first century. In many instances sustainable development has been synonymous with the discourse of ecological modernisation. Ecological modernisation, as a discourse, has been proposed as an entreating means to reach the ideal of development that is sustainable, but has by and large only been tested within developed nations. There is, however, a prominent academic debate centred on the potential social and environmental justice concerns that may emanate from the promotion of ecological modernisation in environmental policy. This research project aimed to understand the degree to which ecological modernisation has been embraced in South Africa, and the environmental justice implications of this adoption. This was in an attempt to build an environmental justice policy framework for ecological modernisation in a bid to address environmental justice concerns. South African energy policy and practice was investigated in order to do this. Civil society hold an esteemed position in ecological modernisation, and as such in-depth, semi-structured interviews were conducted with a number of civil society activists who are involved in a range of campaigns for environmental justice. Their insights and solutions to potential environmental justice concerns that would result from using ecological modernisation were investigated. This was done in an attempt to build a list of environmental justice principles that can possibly be used to inform policies based on ecological modernisation in order to ensure just development. These criteria address the role of government, the role of society at large, as well as industry, and for the most part seek to understand if the disparate power dynamics that exist amongst these three actors can potentially be addressed. South African energy policies were analysed for evidence of these justice principles. It was found that South African energy policies do not address environmental justice in any measure that would truly allow for justice to be put into the practice of governing the environment. Therefore, by incorporating these environmental justice principles into ecological modernisation, ecological modernisation can potentially be stronger in approach to sustainable development than it presently is.

Full textAbstract:
This dissertation investigates the relationship between electricity market reforms and the development of renewable energy through interviews with policymakers, energy experts, and industry representatives in Brazil. Within the context of market-oriented power reforms initiated in the 1990s, policymakers have attempted to diversify the energy supply and reduce the country’s reliance on hydroelectric power. However, Brazil’s pre-existing hydropower infrastructure has hindered the diffusion of alternative options. By looking at energy auctions and net-metering regulations for wind and solar energy, this research explores the role of independent regulators in facilitating the development of non-hydro renewable sources of energy. While academic and policy debates center on designing public support schemes for renewable energy, this research argues that adaptive regulation can provide opportunities for new technologies that policy instruments alone are unable to achieve. In particular, the governance characteristics of regulatory agencies are critical to the effective articulation of renewable energy policies. Three subnational case studies further demonstrate how states and regions contribute to developing and deploying wind and solar energy technologies.

Mercury was also used, at a large extent, in the Witwatersrand Basin (South Africa) for
gold recoveries until 1915 and is still used in illegal artisanal mining. Consequences of
these activities are the release of mercury to the environment. Nowadays, gold (and
uranium) is also recovered through the reprocessing of old waste dumps increasing the
concern related to mercury pollution.
While much effort has been put in the northern hemisphere to understand and control
problems related to anthropogenic mercury release and its fate to the ecosystem, risk
assessment of mercury pollution in South Africa was based, until very recently, on total
element concentrations only or on non systematic fragmental studies. It is necessary to
evaluate mercury speciation under the country’s semi arid conditions, which are different
to environmental conditions that exist in the northern hemisphere, and characterize
potential sources, pathways, receptors and sinks in order to implement mitigation
strategies and minimize risk.
In this study, analytical methods and procedures have been developed and/or optimized
for the determination of total mercury and the speciation of inorganic and organic forms
of mercury in different sample matrices such as air, coal, sediment, water and biota.
The development of an efficient and cost effective method for total gaseous mercury
(TGM) determination was achieved using nano-gold supported metal oxide (1% wt Au)
sorbents and cold vapor atomic fluorescence spectrometry (CV-AFS). Analytical figures
of merit and TGM concentrations obtained when using Au/TiO2, as a mercury trap, were
similar to those obtained with traditional sorbents.
The combination of isotope dilution with the hyphenated gas chromatography-inductively
coupled plasma mass spectrometry (ID GC-ICP-MS) was also achieved and used
successfully for the speciation analysis of mercury in solid, liquid and biological samples. The developed, or optimized, methodologies were used to estimate the average mercury
content and characterize the speciation of mercury in South African coals, and also to
study the speciation of mercury in selected South African environmental compartments
impacted by gold mining activities.
The obtained average mercury content in coals collected from the Highveld and
Waterberg coalfields (0.20 ± 0.03 mg kg-1) was close to the reported United States
Geological Survey (USGS) average for South African coals. Speciated isotope dilution
analyses and sequential extraction procedures revealed the occurrence of elemental
mercury, inorganic and organo-mercury species, and also the association of mercury
mainly to organic compounds and pyrite.
The environmental pollution assessment was conducted within the Witwatersrand Basin,
at four gold mining sites selected mainly for their mining history and from geophysical
information obtained through satellite images. This study showed a relatively important
pollution in three of the four sites, namely the Vaal River west site near Klerksdorp, the
West Wits site near Carletonville (both in the North-West Province) and the Randfontein
site in the West Rand (Gauteng Province). Only one site, the closed Rietfontein landfill
site in the East Rand (Gauteng Province) was found to be not impacted by mercury
pollution.
The methylation of mercury was characterized in all sites and factors governing the
mercury methylation process at the different study sites were also investigated.
Geochemical models were also used to explain the distribution, transport and fate of
mercury in the study systems.

Full textAbstract:
East Timor is rebuilding its stock of infrastructure after decades of underdevelopment and a wave of violent destruction in 1999. As part of this process the Government of East Timor aims to improve access to electricity from less than five percent of the population today to eighty percent by 2020. An important strategy to meeting this aim will be the use of solar home systems (SHS) in remote rural locations. To develop its policy for the deployment of SHS, the Government of East Timor must decide what size of SHS is optimal. This research investigates whether there is a relationship between SHS size and development.The research adapts an evaluation approach developed by World Bank/UNDP Energy Sector Management Assistance Program. This approach uses a combination of participatory and quantitative tools tailored to the East Timorese context through consultations with rural households about electrification and their use of SHS. Three SHS projects in East Timor were selected for evaluation, each of which had adopted a different sized SHS for their program. The smallest systems installed were 10 Wp single-lamp systems. The largest system was rated at 80 Wp and was supplied with four or six lamps. The third type of system was 40 Wp and provided three lamps
To assess the development impact of these different sizes of SHS, a set of Participatory Evaluation exercises were conducted with seventy-seven small groups of SHS users in twenty four rural communities. These exercises were supplemented with a Socio-economic Household Survey of 195 SHS users. The combined results of these evaluation processes enabled the three sizes of SHS to be compared for two types of benefits—assistance with carrying out important household tasks (i.e. ‘lighting-derived’ benefits) and attributes of SHS which were advantageous in comparison to use of non-electric lighting sources (i.e. ‘intrinsic’ benefits). Analysis of the research results showed that the small 10 Wp SHS provided much of the development impact of the larger systems. For lighting-derived benefits, there was little difference between the development impact of small and large systems. The larger systems provided greater benefit for domestic tasks undertaken in kitchen buildings, since the small and medium sized SHS did not provide lighting in these areas. For intrinsic benefits related to health and convenience, the small systems provided much the same benefits as larger systems. For financial benefits—considered by East Timorese SHS users to be the most important of the intrinsic benefits—smaller systems were found to offer slightly positive benefits due to their lower operating costs. Larger systems, however, were found to have a negative overall financial impact.
The research suggests three significant implications for the design of SHS programs in East Timor and comparable situations elsewhere: programs should focus on providing smaller systems rather than larger ones; systems should be designed to provide a light in the kitchen wherever possible to maximise the overall development impact; and SHS operating costs should be carefully matched to the incomes of rural householders to ensure that operation of the systems can be sustained by user households.

Full textAbstract:
Oregon's ocean waters are a potential source of wind, wave, and tidal energy; of interest to renewable energy entrepreneurs and to the U.S. government as it seeks to bolster energy security. In order to install technology to capture this energy, however, it may be necessary to mitigate conflict with existing ocean space users. The objective of this research was to construct a conflict analysis model in a GIS to answer the following research questions: (1) Within the study area off the coast of Oregon, where are stakeholders currently using ocean space and how many uses overlap? (2) To what extent might existing ocean space use present potential for conflict with renewable energy development? (3) How do various types of uncertainty affect analysis results? (4) What are the implications of these findings for ecosystem based management of the ocean?
All available spatial information on ocean space usage by commercial fishing, commercial non-fishing, recreational, Native American, and scientific communities was gathered. Stakeholder outreach with these communities was used to vet the collected data and allow each to contribute knowledge not previously available through GIS data clearinghouses maintained by government or interest groups. The resulting data were used as inputs to a conflict visualization model written in Python and imported to an ArcGIS tool. Results showed extensive coverage and overlap of existing ocean space uses; specifically that 99.7% of the 1-nm² grid cells of the study area are occupied by at least 6 different categories of ocean space use. The six uses with the greatest coverage were: Fishing – Trolling, Habitat, Military, Fishing - Closure Areas, Protected, and Marine Transportation - Low Intensity. An uncertainty analysis was also completed to illustrate the margin for error and therefore the necessity of appropriate stakeholder outreach during the renewable energy siting process, as opposed to relying only on a GIS.
Ranking of each category by its potential for conflict with renewable energy development demonstrated which areas of the ocean may be particularly contentious. Because rankings are subjective, a tool was created to allow users to input their own rankings. For the purpose of this report, default rankings were assigned to each as justified by the literature. Results under these assumptions showed that space use and potential for conflict were highest between the coast and approximately 30 nm at sea. This is likely because certain space use is limited by depth (e.g., recreational use); there is increased shipping density as vessels approach and depart major ports; and increased fuel costs associated with traveling further from shore.
Two potential applications of model results were demonstrated. First, comparison with existing wave energy permit sites highlighted relative potential for conflict among the sites and the input data detailed the specific uses present. Second, comparison with areas determined most suitable for development by the wave energy industry illustrated that areas of high suitability often also had high rankings for potential for conflict. It appeared that the factors that determined development suitability were often the same factors that drew current ocean space users to those locations.
Current support at the state, regional and federal level under the National Ocean Policy for the use of marine spatial planning as a tool to implement ecosystem based management of the oceans requires that tools such as the one developed in this research are used, to ensure that all components of the marine ecosystem are considered prior to implementation of a management plan. The addition of renewable energy to the current social landscape of the ocean will reduce the resource base for many categories of ocean space use. Model results demonstrated that mitigation of conflict between development and existing space use is not merely a best practice supported by current policy, but a necessity. Results presented a visualization of the social landscape of the ocean that could help managers determine which stakeholders to engage during the initial stage of choosing a site for development.Graduation date: 2012

The rapid and sustained development of the rural regions of South Africa continues to pose an
extraordinary challenge to the development community of the country. Policy makers continue to be overwhelmed by the lack of development in the rural areas in spite of the various efforts made to develop them. A review of the publications and development plans of the study region indicates that the planners have for long been pre-occupied with taking limited perspectives of the development
planning problems. Development plans have been conceived and implemented in terms of individual
sectors instead of looking at their relations with other sectors and regions.
This study seeks to make a contribution to the solution of the development problems of the rural
areas of the former homeland regions by demonstrating how an integrated approach to the research process and to development planning could make a difference to the lives of the rural communities.
This theme is illustrated with reference to the rural energy sector and its relations with the broader regional development problems, challenges and plans of the Sekhukhune district municipality of the Limpopo Province.GEOGRAPHY

At present, the use of other sources of energy other than energy source from crude oil has accelerated. This is due to limited resources of fossil fuel, increasing prices of crude oil and environmental concerns. Alternative fuels such as biofuel are becoming more important because it can serve as a replacement for petroleum diesel due to its comparable fuel properties and cleaner emission. For use in a standard diesel engine, biodiesel can be blended (mixed) with petroleum diesel at any concentration. In this study, transesterification of waste cooking oil with methanol was catalyzed by heterogeneous catalyst TiO2-supported-MgO and the biodiesel produced was characterised. Waste cooking oil (WCO) was used because it is regarded as one of the cheapest feedstock for biodiesel production in that most oils from oil crops are used as food. Waste cooking oil is available in vast amounts each day in every restaurants and fast food outlets worldwide. The waste cooking oil used in this study was laboratory prepared by the addition of 5 wt. % of oleic acid into 95 wt. % of soybeans oil.10 wt. % of titanium-supported-magnesium oxide catalyst (MgO/TiO2) used was prepared by incipient wetness impregnation and characterized using XRF, BET and XRD. These materials were tested with the catalyst for the conversion of waste vegetable oil to biodiesel in presence of methanol and hexane co-solvent. Methanol to oil mole ratio of 18:1 was employed in the transesterification process. When hexane was used as cosolvent, methanol to oil mole ratio of 18:1 and methanol to hexane mole ratio of 1:1 was used. The effects of reaction time, reaction temperature and hexane co-solvent on the waste vegetable oil conversion has been established. The 1HNMR analysis was used to estimate the structure of FAME produced. It was observed that the oil conversion increases with the increased reaction time, reaction temperature and use of hexane as co-solvent.Chemical Engineering

Text in EnglishEnergy is the natural power stored in matter which can be potential and kinetic energy. This occurs in nature in various forms such as chemical energy, thermal energy, electromagnetic radiation, gravitational energy, electric energy, elastic energy, nuclear energy, and rest energy. The scientific research relating to nuclear energy has revealed that atoms are the foundation of matter. In 1905 Albert Einstein initiated the quantum revolution utilising the Newtonian mass-energy equivalence concept in order to put his famous equation: E =mc2, where energy is (E). This facilitated the nuclear research which focused on manufacturing the first atomic bomb. In 1945 the USA acquired its first two atomic bombs which were dropped on Nagasaki and Hiroshima, killing 200 000 people; mostly civilians. But nuclear energy research has been redirected by scientists in order to industrialise nuclear technology in order to address growing power needs. This encouraged policy makers to consider the risks posed by utilising nuclear energy for civil purposes. The shift towards peaceful nuclear energy applications has been motivated by the many valuable contributions to humankind which nuclear energy offers - for instance in the fields of energy generation, human health, agriculture and industry. The nature of nuclear energy lends itself to becoming an important component of the world energy and global economic system. Nuclear energy is a viable option for many countries including South Africa, because it offers an economic and clean source of electricity; the primary engine for socio-economic development. South Africa operates the only two nuclear power reactors in Africa, (Koeberg 1 and Koeberg 2) generating 1.8 GWe. South Africa’s energy supply infrastructure consists fundamentally of coal-fired power plants which pose serious threats to the environment. Therefore, it is assumed that the planned 9.6 GW of new nuclear capacity by 2030 will meet the requirements of South Africa’s policy regarding the diversification of available energy resources to secure energy supply, support economic growth, and contribute to environmental management. Consequently, the legal system which governs nuclear energy programme is intended to prohibit the proliferation of nuclear weapons, ensure security and maintain the safe operation of nuclear facilities.

Full textAbstract:
Countries and governments around the world have accepted the scientific argument on the prevalence and the possible effect of global warming and climate change on the environment, world economy and ultimately human life (Nhamo, 2011). Amongst all industrial corporations, the mining industry is the biggest environmental polluter due to its extractive nature and energy intensive operations. However because of its economic importance, it cannot be abandoned, instead it needs to find a win-win situation, where it continues to succeed but minimizes environmental damage.
This thesis aims to examine the possible impact of clean technology on the sustainability of South African gold mining sector. Specifically, the study aims to determine the drivers behind the move towards clean technologies and methods, identify challenges and opportunities associated with this transition at Harmony Gold’s Kusasalethu mine. This was achieved through using Kusasalethu as a case study to which investigations of the effectiveness of clean technology and methods were carried out. The case study was multidimensional; exploring the effect of clean technology on energy consumption, greenhouse gas emission (GHG), water consumption, cyanide management and Kusasalethu’s financial performance.
While the case study was largely qualitative it involved quantitative data analysis that had to be triangulated with other data sources and data gathering instruments to achieve legitimacy. This meant that the study had to adopt the mixed research methods. The instruments used included; key informant interviews, and document analysis, structured questionnaire and a set of open ended questions that served as interview guide. The qualitative data were analyzed by means of coding, descriptions, typologies, taxonomies and visual representations, whilst quantitative data were processed through Microsoft Excel to generate various forms of descriptive statistics.
The findings indicate that resource consumption (energy, water, cyanide) depends on the mine design and gold output rate. Clean technology implementation at Kusasalethu helped the mine reduce energy consumption and GHG emissions. However scope 2 (indirect GHG emissions associated with energy consumption) is also determined by coal production technologies and methods used by coal mines. Although data on Kusasalethu water and cyanide management and related technologies was not available, the aggregate data for all Harmony Gold mines indicated higher annual water and cyanide consumption during 2010 and 2012. In terms of Kusasalethu’s financial performance and clean technology adaptation, acquisition of clean technologies increased capital expenditure temporarily. However, the positive effects of the clean technology transition and implementation minimized operational cost and increased operational profit greatly. Although adopting clean technologies calls for increased capital expenditure, this study reveals that this expenditure pays off in lower operation costs for the mine and the environment benefits through lower GHG emission. However, clean technologies are yet to impact significantly in lowering water and cyanide consumption levels as they do with energy consumption. The study concluded that clean technology and methods played a positive role on Kusasalethu’s environmental impact and financial performance by reducing energy consumption and GHG emissions. Though, more need to be done in terms of water and cyanide management.Environmental Sciences

Energy conservation, efficiency and renewable energy have become a vital part of everyday life and business. The increase in energy cost and the consequences of greenhouse gas emissions necessitates energy management and in particular energy risk management within organisations. Organisations need to manage the possible negative effect that the increased costs will have within the organisation.
The present research investigated the introduction of a structured approach to energy risk management within the financial services sector of South Africa. The research followed a quantitative, non-experimental research design by using a structured questionnaire. The questionnaire was sent to managers within the financial services sector. The research investigated the criteria for the implementation of a structured approach to energy risk management such as organisational requirements (culture, corporate social responsibility, management, and finance), governance, energy strategies (energy conservation, efficiency and renewable energy), risk identification, risk management and lastly communication and review. The research found that the structured approach to energy risk management should include the context within the organisation namely
organisational requirements, governance and energy strategies. Thereafter the risks within the energy strategies need to be identified, analysed and evaluated, and control measures need to be implemented. It is important to monitor the various energy strategies continuously in order to identify corrections and implement
preventative actions. The strategies need to be reviewed and communicated in terms of the various strategies to all stakeholders within the organisation in order to set continual improvement plans. Risk management should form part of the energy management strategies of organisations. The research showed that energy risk
management plays an important role in the overall business strategy and that the vast majority of financial services organisations have already implemented some form of energy management. There are however aspects that are still lacking within management strategies that need attention.D. Phil. (Management Studies)
