The increased demand for energy determines the need to search for its next sources. One of them could be renewable energy sources, whose importance is increasing, among others, due to the limited resources of fossil fuels. In addition, renewable energy production has many benefits, mainly environmental and economic. Moreover, the social aspects associated with it cannot be ignored. The aim of this work was to discuss selected social benefits resulting from the production of renewable energy. Among the most important advantages of renewable energy sources is their local aspect, since energy production solves many regional problems, mainly related to its transport. The issue of energy security is also essential. In the case of biofuel production, the possibility of involving waste in energy production is extremely beneficial. The use of renewable energy itself directly affects the improvement of the environment, which in turn has a positive effect on people. Nowadays, sustainable development is one of the most critical challenges of humanity. These activities are closely related to the use of renewable energy sources. It is important to pay attention not only to subjects related to the environmental and economic aspects but also the impact of renewable energy sources on society.

The urban energy model is based on imports from external sources. The continuous increase in energy demand due to population growth and development implies increasing resource requirements. The alternative is to use renewable energies that take advantage of urban resources. The diversity of typologies of cities in terms of resources, demands, architectural conditions, infrastructure, or density, makes a specific analysis necessary. This work identifies fourteen factors concerning the planning process that would allow choosing the most appropriate technology for a given city. Through consultation of experts, the existence of the resource is defined as the most prevalent factor, followed by economic conditions; On the other hand, it is detected that environmental aspects such as global warming, eutrophication, or acidification, are the least incidents when selecting technologies.

One of the key tasks for the world community is the development of energy, which is one of the fundamental components of the economy. However, one cannot deny the fact that energy is the main factor in environmental pollution, which leads to the constant search for such types of energy sources that would have a positive impact on the economic development of territories and favourably affect the environment, alternative sources to traditional ones. Currently, there is an energy transformation, the main condition of which is the development of alternative energy technologies. One of the prospects for the economic and environmental development of the territories is the efficient use of renewable energy sources, which are becoming increasingly important in the world community and the global energy balance, and are becoming a substitute resource for traditional fossil energy resources. The article aims to analyse the economic and environmental aspects of the development of renewable energy in Kazakhstan and identify the main prospects. In the framework of the study, the concept of renewable energy sources, their main types are defined, the opinion of various authors regarding the development of renewable energy sources is described, the main directions aimed at stimulating the development of renewable energy are considered. The development of renewable energy in Kazakhstan in comparison with other countries (USA, China, Germany, Russia) is considered, the main problems are identified, the prospects for the development of renewable energy are also considered. The prospects for further research are determined by the subsequent study of the development of renewable energy sources, taking into account economic and environmental aspects. The article is of practical value in the framework of generalising data on the development of renewable energy in Kazakhstan and foreign countries.

The article deals with a current trend of the global energy market, which is characterized by rising tension in relations between the performers of the energy market regulation mechanisms, and it leads to the emergence of alternative energy sources. The article is called to identify the causes of renewable energy markets nascence, to make comparative description of Ukrainian and European Renewable Energy Markets attractiveness, and to characterize the state policy change in a renewable energy market. Different interpretation of nature and classification of the field of renewable energy in foreign and Ukrainian approaches shows the problem of legal criteria of renewable energy markets regulation. It is proved the existence of double barrier penetration of the European market for renewable energy for Ukrainian companies, which includes compliance with the accepted EU Directives and compliance with the Rules of each member individually. The presence of clearly defined standards and certificates of quality for the European market allows producers to show the competitiveness of Ukrainian products in the international market and stimulate Ukrainian manufacturers. The presence of clearly formulated laws, stable and balanced political and legal environment of the EU allows Ukrainian producers of renewable energy to develop such a strategy that considers the time factor, as the primary parameter of competitiveness in international business. The market of solid biofuels in EU is under formation, its development timeframe and uncertainty of environmental risks becoming is especially important for Ukrainian producers.

The use of renewable energy sources offers opportunities for regional and local development. Thus, it can be appreciated that the use of renewable sources can stimulate the development of local communities. An advantage is also given by an increased security in terms of local energy supply, but also by a reduction in energy transport losses. Recently, there has been some interest in investing in the development of energy generation technologies and especially in renewable sources. For the period 1990-2020, a comparative situation of gross electricity production and electricity production capacities for renewables is presented. Pollution and climate change can affect both the production and consumption of electricity. There has been interest in using more and more diverse sources. Given the interest in reducing energy consumption in transport, important measures are needed to increase the energy efficiency of transport. In the article, an analysis is made of the share of renewable energy in the final gross energy consumption, for the period 2004-2020, with particularization for the transport sector.

Recently, legal literature has given attention to the problems of innovative energy. Despite the negative consequences of the current global economic crisis, the ways out of it are in the mainstream of the country’s transition from the export of raw materials to the resource-innovative development with a qualitative renewal of the energy sector. These tasks are set in the strategic planning documents that determine the vector and prospects of energy, scientific and technological and other areas of development. Achievement of goals and long-term quality guidelines for the development of the energy sector on an innovative development path is associated, among other things, with alternative energy, the expansion of the use of renewable energy sources. The paper shows the possibilities and prospects of their use for small energy facilities, energy-deficient areas, and regions with decentralized energy supply. The advantages of using green technologies, renewable types of energy are manifested in energy conservation, energy security, reducing the negative impact on the environment, and solving environmental problems. The absence of a regulatory legal framework for the development of alternative energy is revealed; gaps in energy legislation in terms of innovative energy, stimulation of the introduction of innovative technologies, and the use of renewable energy sources are highlighted. The necessity of highlighting this direction in the energy strategy, other strategic documents in the field of environmental, economic development, energy efficiency and safety has been substantiated. The result of the study is new approaches to the formation and implementation of state policy, as well as the improvement of legislation in the field of innovative energy development.

Full textAbstract:
Energy production from biomass is now a very popular trend in energy generation. These initiatives are supported by the European Union legislation and state governments. Undoubtedly, the idea of renewable energy production can be justified and promising. However, it should be considered from a wider perspective of supply chain than merely focusing on the share of renewable sources in total energy production. The economic and ecological importance of biomass use to energy generation largely depends on the logistics of biomass supply to power plants. The location of biomass sources and the organization of supply are very important stages that impact on final economic results of energy production. Furthermore, the improper choice of means of transport and process organization for managing renewable sources of energy might have a negative ecological effect. Therefore, the authors attempted to analyze the cost-related aspects of biomass supply (including the seasonal biomass price fluctuation) to the analyzed power plant and the effect of this factor on financial results of energy production.

Full textAbstract:
The United Kingdom is particularly well endowed with renewable energy sources relating to wind, waves and tide as well as the normal waste products arising from an industrialized society. These and other renewable energy sources have much technological scope for development but less scope for economic use. Government support for these industries has been significant in recent years in allowing a number of schemes to become commercially possible. The technologies are diverse, the design engineering is in its early stages in many cases and the extent of the eventual integration of such energy sources into existing energy supply systems is not easy to foresee. Aspects of the economic, institutional and environmental factors influencing the exploitation of renewable energy sources for electricity generation are reviewed along with an assessment of the present developments in the various technologies. The need for further support within a long-term view of the whole energy supply scene is stressed as necessary to balance shorter-term commercial considerations.

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.

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:
Thesis (MTech (Environmental Management))--Cape Peninsula University of Technology, 2018.South Africa is taking a continental lead towards the transition of the green economy, and the energy sector has been identified as one of the cornerstones integral in this transition. This transition pays attention to alternative energy sources to gradually replace fossil fuels. Recently, the production of ethanol is seen as an energy source that is an integral player in achieving a green economy. The ethanol production project is linked to the improvement of the economy, and social well-being concomitant with the enhancement of the environmental quality tenets embodied by the green economy. Scholars have noted that these projects tend to ignore socio-economic realities of under privileged people especially in rural areas and small towns. While the green energy is often presented by the state there is, however, no evidence of the positive as well as negative impacts of ethanol projects on improving the livelihoods of the local communities or contributing to the substance of the local economies while protecting the quality of the environment. This thesis explored the subject of ethanol projects as green economic models in the context of the ethanol project in Cradock. The thesis investigated the socio-economic implications of the ethanol project in Cradock as a green economic model. The research study argues that the inclusion of the local people in decision making for the ethanol project is crucial to securing their benefits from the project. This means that local people should be involved early in the decision making process. Failure to engage the local residents in the initial stages of decision making, may create a lack of sense of ownership resulting in a lack of socio-economic benefits for the residents. The research study adopted a qualitative research design and an inductive approach. The ethanol project in Cradock was used as a case study for the research, and two sampling techniques, purposive sampling and random sampling were used. Interviews, questionnaires and observations were used to collect data from the residents of Cradock, the business sector (hospitality, tourism and agricultural retail), the emerging farmers, the farm workers, the Agrarian Research Development Agency, and Government Departments (Local Economic Development, Department of Agriculture, Department of Rural Development and Land Reform). The findings illustrate that the ethanol project in Cradock is not consistent with the tenets of a green economic model. The results suggested that the project does not improve the livelihood of the community or contribute to the sustenance of the local economies while protecting the quality of the environment. From an environmental perspective, while the ethanol project regarding providing ethanol fuel contributes positively to the global green agenda, it deteriorates the quality of the local environment. The project pollutes the local environment which is a source of livelihood for the local people and the economy. Therefore, the adverse effect of the project on the local environment contributes to a negative effect on the local economy and livelihood of the residents. The results also revealed that the project stakeholders, particularly the residents of Cradock and the emerging farmers, were not involved in the early stages of the project where the benefits were determined. As a result, the stakeholders do not have a sense of ownership of the project, and there are uncertainties about the sustainability of their socio-economic benefits. The ethanol project introduces a shift from the traditional commercial agriculture to the production of biofuel feedstock. This causes an effect on the local economy and livelihood because traditional commercial agriculture has sustained the town for more than 200 years. The thesis raises questions about the notion that ethanol projects are green economic models.

Thesis (MBA)--Stellenbosch University, 2011.Gaia Power is a South African start-up in the renewable energy industry. Among other products, they developed a wave energy converter, which is a device used to extract energy from ocean waves. This research deals with the economic feasibility study of the wave energy converter. Wave energy is a young field of research, especially in the South African context. Therefore sources for multiple angles of the project had to be found, analysed and brought into the Gaia Power context. Understanding the cost drivers of a wave energy plant was the foundation of the research itself. The Gaia Power specific levelised cost of electricity generation was calculated based on actual supplier quotes, reference costs found in the literature as well as assumptions. Still, such a calculation is actually more an estimation due to a high uncertainty level in all cost components. Especially the construction cost as well as the discount rate used have therefore been tested for sensitivity. Gaia Power‟s target production cost was R0.54 kWh, which equalled the Eskom tariff at the time of this research. Taking into account a R0.10/kWh fee payable to Eskom, the target cost sank to R0.44, which is about 25 percent lower than the minimum value for electricity generation cost found in the literature. This target was therefore expected to be and proved to be difficult to reach. The calculated levelised electricity cost was R0.99/kWh, with a possible range of R0.54/kWh to R1.60/kWh observed in the sensitivity analysis. These results show that the Gaia Power wave energy converter in the given specifications was not economically feasible. It was therefore recommended to rethink the specifications in order to reduce construction cost, which proved to be the largest cost driver. Besides the quantitative findings, this research also has a strong qualitative side. During the whole research it became obvious that there was an overall high risk level in the project due to the lack of experience with wave energy in general and in South Africa specifically, as well as the high impact of weather on the construction. Those risks were identified, analysed and recommended mitigation actions were derived.

Full textAbstract:
Bioethanol is likely to be a large contributor to the fuel sector of industry in the near future. Current research trends are geared towards utilizing food crops as substrate for bioethanol fermentation; however, this is the source of much controversy. Utilizing food crops for fuel purposes is anticipated to cause massive food shortages worldwide. Cellulose is the most abundant renewable resource on earth and is subject to a wide array of scientific study in order to utilize the glucose contained within it. Waste paper has a high degree of cellulose associated with it, which makes it an ideal target for cellulose biotechnology with the ultimate end goal of bioethanol production. This study focussed on producing the necessary enzymes to hydrolyse the cellulose found in waste paper and using the sugars produced to produce ethanol. The effects of various printing inks had on the production of sugars and the total envirorunental impact of the effluents produced during the production line were also examined. It was found that the fungus Trichoderma longibrachiatum DSM 769 grown in Mandel's medium with waste newspaper as the sole carbon source at 28 °C for 6 days produced extracellular cellulase enzymes with an activity of 0.203 ± 0.009 FPU.ml⁻¹, significantly higher activity as compared to other paper sources. This extracellular cellulase was used to hydrolyse waste newspaper and office paper, with office paper yielding the highest degree of sugar production with an end concentration of 5.80 ± 0.19 g/1 at 40 °C. Analysis by HPLC showed that although glucose was the major product at 4.35 ± 0.12 g/1, cellobiose was also produced in appreciable amounts (1.97 ± 0.71 g/1). The sugar solution was used as a substrate for Saccharomyces cerevisiae DSM 1333 and ethanol was produced at a level of 1.79 ± 0.26 g/1, the presence of which was confirmed by a 600 MHz NMR spectrum. It was found that cellobiose was not fermented by this strain of S. cerevisiae. Certain components of inks (the PAHs phenanthrene and naphthalene) were found to have a slight inhibitory effect (approximately 15% decrease) on the cellulase enzymes at very high concentrations (approximately 600 μg/1 in aqueous medium), while anthracene had no effect. Whole newsprint ink was shown not to sorb glucose. The environmental analysis of the effluents produced showed that in order for the effluents to be discharged into an aqueous ecosystem they would have to be diluted up to 200 times. They were also shown to have the potential to cause severe machinery damage if reused without proper treatment.

Thesis (MScEng)-- Stellenbosch University, 2013.ENGLISH ABSTRACT: Climate change that results from greenhouse gases (GHG’s) released from the burning of fossil fuels, together with the rising price of oil, have sparked interest in renewable biofuels. The production of biofuels also presents potential socio-economic benefits. There are two types of technologies for bioethanol production: · First generation bioethanol is produced from food feedstocks such as juice of sugarcane. · Second generation bioethanol is produced from non-food feedstocks (lignocellulosic materials). This project is concerned with 1st and 2nd generation bioethanol production from sugarcane juice and bagasse and the integration of these technologies. This project comprises a combination of experimental and process modelling work to assess energy efficiencies and the economic viability of integrated and stand-alone processes in the sub-Saharan African context. First generation fermentation experiments were conducted and high ethanol concentrations of up to 113.7 g/L were obtained. It was concluded that a recombinant yeast strain may be able to replace a natural hexose fermenting yeast for 1st generation fermentations to reduce costs. 2nd generation fermentation experiments were performed and ethanol concentrations of close to 40 g/L were obtained. Combinations of 1st and 2nd generation fermentation experiments were performed to improve the 2nd generation fermentation. In one of the experiments it was concluded that the combination of 1st and 2nd generation fermentations significantly improved the 2nd generation fermentation with an overall ethanol concentration of 57.6 g/L in a shorter time than for the pure 2nd generation experiments. It was determined from washing and pressing experiments that pressing the pre-hydrolysate liquor out of the pre-treated bagasse will sufficiently lower the levels of inhibitors in a 2nd generation fermentation when using a hardened yeast. Some of the data from the 1st generation experiments were used along with literature data to model a first generation process in Aspen Plus® which processes 493 tons of cane per hour (tc/hr). Pinch heat integration was used to reduce the utility requirements. The process used the bagasse that was generated to co-produce steam and electricity. The excess electricity was sold for additional revenue. In one scenario the excess bagasse was determined at 57.5%. This bagasse was sold to a stand-alone 2nd generation plant. The first generation process produced 85.5 litres of ethanol per ton of cane (L/tc), the integrated process produced 128 L/tc while the stand-alone 2nd generation process produced 185 litres of ethanol per ton of bagasse (50% moisture) or 25.5 L/tc. The amount of excess electricity that was produced ranged from 14.3 to 70.2 kWh/tc. Economic analyses were performed using South African economic parameters to resemble the sub- Saharan African context. Data from the 1st generation process model and literature data for integrated 1st and 2nd generation and stand-alone 2nd generation processes were used for the analyses. It was found that the integrated plant is the most economically viable (IRR = 11.66%) while the 1st generation process basically broke even (IRR = 1.62%) and the 2nd generation process is unviable. This was as a result of high sugarcane prices and too few incentives for 2nd generation ethanol.
AFRIKAANSE OPSOMMING: Klimaatsverandering wat veroorsaak word deur kweekhuisgasse wat vrygestel word deur die verbranding van fossielbrandstowwe en die stygenede olieprys het belangstelling in hernubare biobrandstowwe laat opvlam. Die produksie van biobrandstowwe hou ook potensiële sosioekonomiese voordele in. Daar is twee tegnologieë vir bioetanol produksie: · Eerste generasie bioetanol word vanaf voedsel bronne soos suikersap geproduseer. · Tweede generasie bioetanol word van nie-voedsel bronne (lignosellulose materiaal) geproduseer. Hierdie projek handel oor 1ste en 2de generasie bioetanol produksie van suikersap en suikerriet bagasse en die integrasie van hierdie tegnologieë. Hierdie projek bestaan uit ‘n kombinasie van eksperimentele- en prosesmodellering werk om die energiedoeltreffendheid en ekonomise vatbaarheid van geïntegreerde en alleenstaande prosesse in die sub-Sahara konteks te ondersoek. Eerste generasie fermentasie eksperimente is uitgevoer en hoë etanol konsentrasies van tot 113.7 g/L is gekry. Dit was bepaal dat ‘n rekombinante gisras ‘n natuurilke heksose fermenterende gisras kan vervang vir 1ste generasie fermentasies om kostes te bespaar. 2de generasie fermentasie eksperimente is gedoen en etanol konsentrasies van amper 40 g/L is behaal. Kombinasies van 1ste en 2de generasie fermentasie-eksperimente was uitgevoer om die 2de generasie fermentasie te verbeter. In een van die eksperimente is dit bepaal dat die kombinasie van 1ste en 2de generasie fermentasie die 2de generasie fermentasie beduidend verbeter het met ‘n etanol konsentrasie van 57.6 g/L en dít in ‘n korter tyd as vir die suiwer 2de generasie eksperimente. Dit was bepaal vanuit pers- en was eksperimente dat om die pre-hidrolisaat vloeistof uit die stoombehandelde bagasse te pers, die vlak van inhibitore in ‘n 2de generasie fermentasie voldoende verlaag vir die gebruik van ‘n verharde gis. Van die data van die 1ste generasie eksperimente was saam met literatuurdata gebruik om ‘n 1ste generasie proses in Aspen Plus® te modelleer wat 493 ton suikerriet per uur prosesseer (tc/hr). Pinch hitte integrasie was gebruik om die dienste vereistes te verminder. In die proses word die bagasse gebruik om stoom en elektrisiteit te genereer. In een geval was die oortillge bagasse bepaal as 57.5%. Hierdie bagasse was verkoop aan ‘n alleenstaande 2de generasie aanleg. Die eerste generasie proses het 85.5 liter etanol per ton suikerriet geproduseer (L/tc), die geïntegreerde proses het 128 L/tc geproduseer terwyl die 2de generasie proses 185 liter etanol etanol per ton bagasse (50% vog) of 25.5 L/tc geproduseer het. Die hoeveelhede oortillige elektrisiteit wat geproduseer is wissel van 14.3 tot 70.2 kWh/tc. Ekonomiese analieses is gedoen met Suid-Afrikaanse ekonomiese parameters om die sub-Sahara Afrika-konteks uit te beeld. Data van die 1ste generasie prosesmodel en literatuurdata van geïntegreerde 1ste en 2de generasie en alleenstaande 2de generasie prosesse was vir die analieses gebruik. Dit is bepaal dat die geïntegreerde model die mees ekonomies vatbare model is (IRR = 11.66%) terwyl die 1ste generasie proses basies gelyk gebreek het (IRR = 1.62%) en die 2de generasie proses is ekonomies onvatbaar. Hierdie bevindinge is as gevolg van hoë suikerrietpryse en te min aansporings vir 2de generasie etanol.

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.

Full textAbstract:
Renewable energy has become an important feature of most modern economies with clean and non-exhaustible sources of power being given a greater significance. Wind energy is one of the favoured renewable, as it is (2013) generally the cheapest and most mature technology available for commercial use. The South African government, as outlined by the Department of Energy's Integrated Resource Plan (IRP), aims to install 5 GW (Gigawatts) of wind energy by 2020. However, South Africa has had little experience in the wind energy industry which is limited to two projects, Klipheuwel (2002) and Darling (2008). Much effort has been dedicated to calculating balance sheet costs, which carries uncertainty due to the high reliance on country specific and site specific variables. An aspect which deserves more attention, and is often ignored, is the public‟s attitudes towards local wind farm developments, which have been known to "make or break" a project during the planning stages. Public backlashes have mostly been concerned with the visual "intrusiveness" of wind farms in the landscape. Detrimental effects on scenery, while seemingly innocuous, are acknowledged as being the single largest barrier to successful wind farm development. Individuals within an area become sentimentally attached to their surroundings, where significant rapid changes in the landscape are viewed as "damage". Economics recognises such declines in scenic resources as market failures, where an externalised cost is passed on to the public and is often not accounted for by private parties responsible for the liability. The primary objective therefore was to measure the magnitude of the visual impact, caused by the Waainek Wind Farm, on the Grahamstown community. Conventional NIMBY¹ (not in my back yard) reasoning, which seeks to explain local wind farm resistance, has attracted criticism with regard to its simplistic approach to wind farm problem identification. Contemporary arguments propose that NIMBY is a poor explanation for the trouble experienced on the local level because it groups problems into one all-encompassing term, leaving much of the discontent unexplained. Instead, the NIMBY explanation is really a broad set of unattended problems, largely resulting from the unsound practices present in the public participation process. Insufficient community involvement and disparities in the negotiation power structures have become the recent focus in wind farm literature. Essentially, these disparities force opposition groups to select factors which may seem more serious to developers, leading to ineffective remedial measures because the core underlying problems are not being remedied. Thus these considerations formed an additional area of investigation. No NIMBY effect was found for the Grahamstown community, as support for both the local and general level was roughly 80%. The public participation process on the other hand revealed that while many found the practices of the developer to be unfair, attitudes towards the wind farm were not adversely affected, especially for the lower income Grahamstown East areas. While the public participation process in this instance did not have any effect on people’s attitudes, careful inspection of the circumstances need to be given. Wind farms are new to South Africa, where the novelty and benefits are the focus of enthusiasm. Job opportunities as well as clean energy are positive drivers for attitudes; however given time, once the anticipation for wind farms dulls, real problems may be revealed. Thus it is crucial to implement good practice procedures during the public participation process, especially when national adoption rates of wind energy are low. Early implementation of an effective public participation process system will ensure that when major problems do arise in future projects, experience and institutional processes would have had ample opportunity to evolve appropriately over a period of time. The double bounded Contingent Valuation Method was used to value the impact of the wind farm on the Waainek scenery through a hypothetical scenario based procedure which presented pictures of the landscape before and after the wind farm had been installed. Based on the perceived impact of the wind farm, respondents were asked their Willingness to Pay to relocate the development, based solely on visual impacts. Learning design Contingent Valuation (Bateman et al., 2008) is a novel technique employed to familiarize respondents with the hypothetical market institution as well as the scenic goods being valued. Average Willingness to Pay was found to be R67 per month, with a final total monthly negative visual impact of R104,000 to R121,000 per month for the entire Grahamstown community. Grahamstown Central (middle-high income) residents were more likely to pay than Grahamstown East (low-middle income) East residents because of socio-economic differences present in each area. A ranking exercise determined that while negative visual impacts are present, the overall benefits derived from the wind farm are potentially much higher. Additionally, positive scenic improvements were found, but were not measured due to time constraints, and would have worked to reduce the net visual impact of the Waainek Wind Farm. ¹Problem where individuals support the general concept of wind power, but when it comes to local implementation, opposition to the development arises within the same group.

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 work demonstrates the effects of the active use of renewable energy sources (RES) in the unified energy system (UES) of Ukraine, in particular, maintaining the balance in the network for its reliable and high-quality operation. In the energy strategy for the development of renewable energy sources in Ukraine until 2035, a rapid increase of the installed RES capacity is planned, i.e. the task of maintaining balance sheet reliability in the conditions of an increase in the share of RES in the UES of Ukraine is quite urgent. Forecasting of the electricity balance is based on the generation forecast, electricity consumption in a given period of time, as well as fuel reserves and the volume of generating capacity reserves. Renewable energy sources have a non-uniform nature of generation, and therefore endanger aspects of balance reliability. This problem is key for Ukraine in light of the integration of Ukraine's energy system into the European ENTSO-E network. As a result of the conducted research, it can be stated that the improvement of the situation is possible only with an integrated approach and the implementation of appropriate technologies, namely: technical, economic and institutional technologies. The introduction of technologies will make it possible to improve monitoring and management of energy systems; economic implementations will contribute to the reform of retail pricing and taxation of electricity supplies, taking into account the payment they supply for electricity and covering part of the cost of the general infrastructure; institutional innovations will change the functions and responsibilities of management subjects. Improving coordination between transmission and distribution network operators will become a priority.

Both U.S. and world economies have long depended on fossil energy (coal, oil, and natural gas). Supplies of fossil energy are expected to decline in the future and become more expensive. Meanwhile, their use contributes to the accumulation of greenhouse gas in the atmosphere. Therefore, an urgent need exists for renewable energy sources. In order to enhance the global competitiveness of the U.S. in renewable energy manufacturing, there is a dramatic need for a skilled workforce that has been trained in this field. A survey on renewable energy courses at more than 100 U.S. universities has been conducted. It is found that manufacturing aspects of all forms of renewable energy are not emphasized, and there are no sophomore-level courses that cover manufacturing of all forms of renewable energy at these universities.

A deterministic quantitative model has been developed for use to compare the technical, economical and environment feature of various electric power generating plants. The model, which is based on matrix operations, is used in evaluating the various aspects of energy sources available for the electricity generation systems in a developing country. Several energy sources are chosen which could be considered for production of electricity to meet current and future electricity demands. A complete set of energy sources will include fossil fuel fired power plants, nuclear power plants, and natural-renewable energy power plants. A customized computer code is developed to evaluate the overall function for each system from the performance corresponding to the selected energy attributes includes five area of concerns; energy economy, energy security, environmental protection, socio-economic development and technological aspects for the electric power generations. The model developed in this study is applied to the Indonesian’s electric power sector development. Most of the data required for the model application are obtained from various sources related to power industry in Indonesia, such as the Electricity Generating Authority of Indonesia (Perusahaan Listrik Negara, PLN), Government of Indonesia, World Bank, Asian Development Bank, United Nations, and other sources, both in published and public domains. The optimization technique is kept flexible so that it can accommodate other attributes that will be found to be important according to the decision maker’s preference. By so doing, the model virtually can be used to attack any decision problem with various different attributes to reach an optimal decision concerning the selection of energy sources for electricity generation. The result of this study will be a rank of energy sources for Indonesia power generation systems based on the composite distance of each alternative to the designated optimal source of energy.

Nuclear power plants are used extensively as base load sources of electricity. This is the most economical and technically simple mode of operation. In this mode, power changes are limited to frequency regulation for grid stability purposes and shutdowns for safety purposes. However for countries with high nuclear shares or desiring to significantly increase renewable energy sources, the question arises as to the ability of nuclear power plants to follow load on a regular basis, including daily variations of the power demand. This paper give a detailed analysis of the technical and economic aspects of load-following with nuclear power plants, and summaries the impact of load-following on the operational mode.

First and foremost, the main inspiration for the specific problematics in this paper is solar energy as clean and profitable energy for businesses in the Republic of North Macedonia. The question that arises as the basis is finding the reason why the progress in the sector of renewable energy sources in this country is still slow and insufficient. The results and conclusions of the research shall be achieved via comprehensive analysis, and by finding the answer to the posed question through the: theoretical analysis, the inductive and deductive methods, as well as description shall be used, whereas the techniques utilized shall be questionnaires, interviews, observations. By summarizing in one place all the theoretical and empirical aspects, we are finding the answer to the main question asked: One of the possible reasons for this actual situation is the fact that so far there is no possibility in this country for individuals to be involved in the process of production and transmission of electricity in the energy system. The goal is achieved in this paper through providing specific guidelines and suggestions regarding the improvement of the legal framework in the Republic of North Macedonia, emphasizing on benefits if the households are allowed to deliver their produced solar energy and considering the possible ways to remove the determined obstacles for implementing this idea.

Full textAbstract:
System analysis is a key research document in the decision-making function related to the construction of small renewable energy sources in a given area. The problem must be viewed with multiple aces. When it comes to opportunities, it is crucial to analyze energy potentials, investment opportunities and economic effects. The issue of restrictions should be viewed from the aspect of environmental protection, other security risks and the aspect of long-term energy policy of legal regulations. A special segment of the analysis should be the analysis of domestic knowledge for the successful management of the project of construction of small renewable sources. Analogous to the production of industrial products in small plants and small series, the production of electricity in small renewable sources has a much higher cost price than in large sources. Due to this fact, the production of electricity in small sources of electricity is profitable if it is not delivered through distribution systems, but is delivered directly to the consumer in the immediate vicinity. The construction of modern process industry plants that would have their own electricity from renewable sources is a development opportunity for Serbia. In the variant of more numerous approach, space is opened for the development and production of equipment for small sources of electricity in Serbia

Full textAbstract:
A growing number of countries are committed toreduce their carbon emissions and are transitioning towards renewable and clean energy sources, leading to an in crease in demand formetals and minerals. This is especially the case for a short list of what are called "critical minerals" which are considered essential to economic development, including the transition to a low-carbon economy and national security. There liability of their supply chain raises concerns considering geological scarcity, difficulty to extract and/or political factors influencing their availability. At the same time, public awareness and perception of geoscience are eroding and there is more and more reluctance towards mining projects, even from traditionally favourable communities. To face this challenge, promote public interest and outline the contribution of geological science to society, geoscientists of the Geological Survey of Canada (GSC-Québec) have designed and put together a portable display that includes a suite of mineral and metal samples considered critical for the sustainable success of Canada's transition towards a clean and digital economy. The display is a user-friendly toolkit that can be used by any GSC geoscientists during outreach activities, in classrooms as well as during public open houses. It comes with straightforward pedagogic material and content, along with presentation scenarios. To broaden and adapt the workshops to specific expectations, additional toolkits were developed and all are contained within easy to carry travel cases. These cover a variety of topics and can be presented as stand-alone displays or be used complementary to one another. For example, the "Mines and minerals" collection may serve as a supplement to the "Critical minerals" display to present every day objects in which minerals are used as well as ores amples from active mines to illustrate the intertwining between mining activities and our everyday lives. Another display covers the ever-popular fossils thematic with the "Sedimentary rocks and fossils" collection and gives an opportunity to address key geoscience themes such as life evolution and biological crisis along with groundwater reservoirs and resources. The "Magmatic rocks" display touches on the formation of rocks from magmas, the different types and active processes of volcanoes, and discusses the risks and benefits related to volcanic activity. Hopefully, these four ready-to-use portable displays will encourage more GSC geoscientists to engage in public oriented activities to make geosciences more accessible, change perceptions and offer an overall tangible scientific experience for people.
