Full Text Available This paper studies the feasibility of renewable energy as a substitute for nuclear and energy by considering Korean customers' willingness to pay (WTP. For this analysis, we use the contingent valuation method to estimate the WTP of renewable energy, and then estimate its value using ordered logistic regression. To replace nuclear power and fossil energy with renewable energy in Korea, an average household is willing to pay an additional 102,388 Korean Won (KRW per month (approx. US $85. Therefore, the yearly economic value of renewable energy in Korea is about 19.3 trillion KRW (approx. US $16.1 billion. Considering that power generation with only renewable energy would cost an additional 35 trillion KRW per year, it is economically infeasible for renewable energy to be the sole method of low-carbon energy generation in Korea.

Does FDI influence renewable energy consumption? An analysis of sectoral FDI impact on renewable and non-renewable industrial energy consumption

International Nuclear Information System (INIS)

Doytch, Nadia; Narayan, Seema

2016-01-01

This study examines the link between foreign direct investment (FDI) and energy demand. FDI is a source of financing that allows businesses to grow. At the same time, FDI can be a source of innovation that promotes energy efficiency. Existing evidence on the impact of aggregate FDI inflows on energy consumption is scarce and inconclusive. In the current study, we disaggregate FDI inflows into mining, manufacturing, total services, and financial services components and examine the impact of these FDI flows on renewable – and non-renewable industrial energy – sources for 74 countries for the period 1985–2012. We employ a Blundell–Bond dynamic panel estimator to control for endogeneity and omitted variable biases in our panels. The results point broadly to an energy consumption-reducing effect with respect to non-renewable sources of energy and an energy consumption-augmenting effects with respect to renewable energy. We find that these effects vary in magnitude and significance by sectoral FDI. - Highlights: • FDI generally discourages the use of unclean energy. • Economic growth promotes non-renewable energy consumption. • Service FDI save energy and encourage the switch to renewable energy. • Mining FDI to low and lower middle-income panels save energy. • These results are mainly consistent with the FDI halo effect.

Renewable energy facilities have been installed in many regions, because of their possibility to be an alternative to fossil fuels for mitigating global warming. Besides the profitability of renewable energy businesses, indirect economic effects of installing renewable energy facilities should be clarified. This study examines the possibility that the renewable energy facilities give renewed impetus to regional economic progress. The economic effects are analysed with input-output techniques in a rural area in Japan. As a consequence, both positive and negative effects on the rural economy are derived. In addition, we will focus on the changes in sectors such as construction, business services, banking, etc. as a result of economic activities for renewable systems. The business benefits of renewable energy system are discussed. (author)

Non-renewable and renewable energy consumption and CO2 emissions in OECD countries: A comparative analysis

International Nuclear Information System (INIS)

Shafiei, Sahar; Salim, Ruhul A.

2014-01-01

This paper attempts to explore the determinants of CO 2 emissions using the STIRPAT model and data from 1980 to 2011 for OECD countries. The empirical results show that non-renewable energy consumption increases CO 2 emissions, whereas renewable energy consumption decreases CO 2 emissions. Further, the results support the existence of an environmental Kuznets curve between urbanisation and CO 2 emissions, implying that at higher levels of urbanisation, the environmental impact decreases. Therefore, the overall evidence suggests that policy makers should focus on urban planning as well as clean energy development to make substantial contributions to both reducing non-renewable energy use and mitigating climate change. - Highlights: • Examine the relationship between disaggregated energy consumption and CO 2 emission. • The STIRPAT econometric model is used for empirical analysis. • Investigate the popular environmental Kuznets curve (EKC) hypothesis between urbanisation and CO 2 emissions. • Non-renewable energy consumption increases CO 2 emissions whereas renewable energy consumption decreases CO 2 emissions. • There is evidence of the existence of an environmental Kuznets curve between urbanisation and CO 2 emissions

Al-Ghamdi, Sami G; Bilec, Melissa M

2016-05-03

Adopting a green building rating system (GBRSs) that strongly considers use of renewable energy can have important environmental consequences, particularly in developing countries. In this paper, we studied on-site renewable energy and GBRSs at the system level to explore potential benefits and challenges. While we have focused on GBRSs, the findings can offer additional insight for renewable incentives across sectors. An energy model was built for 25 sites to compute the potential solar and wind power production on-site and available within the building footprint and regional climate. A life-cycle approach and cost analysis were then completed to analyze the environmental and economic impacts. Environmental impacts of renewable energy varied dramatically between sites, in some cases, the environmental benefits were limited despite the significant economic burden of those renewable systems on-site and vice versa. Our recommendation for GBRSs, and broader policies and regulations, is to require buildings with higher environmental impacts to achieve higher levels of energy performance and on-site renewable energy utilization, instead of fixed percentages.

Opportunities for private investments in renewable energies were explored using a stated-preference investment allocation instrument. Allocation alternatives included conventional and renewable energy investments. Among renewable energy investments, solar and wind energy were ranked the highest while grass and wood-based technologies were at the bottom of the renewable energy list. This ranking mirrors the allocation of investments in sustainable energy technologies in global markets. Results were analyzed using a two-limit tobit model which suggests that certainty of investments, a diversified portfolio and expectation on financial returns were the primary drivers behind funds allocated to renewable energy investments. Using cluster analysis, twenty-three percent of our sample of current and future investors was identified as individuals most willing to invest in renewable energies. (author)

Renewable energy planners in developing countries should be cautious in using analytical tools formulated in developed countries. Traditional energy consumption, economic and demography transitions, high-income inequality, and informal economy are some characteristics of developing countries that may contradict the assumptions of mainstream, widely used analytical tools. In this study, we synthesize the debate in previous review studies on energy models for developing countries and then extend the scope of the previous studies by highlighting emerging methods of system thinking, life cycle thinking, and decision support analysis. We then discuss how these tools have been used for renewable energy analysis in developing countries and found out that not all studies are aware of the emerging critical issues in developing countries. We offer here a guidance to select the most appropriate analytical tool, mainly when dealing with energy modeling and analysis for developing countries. We also suggest potential future improvements to the analytical tool for renewable energy modeling and analysis in the developing countries.

Dale, Michael

2012-01-01

This paper offers a review of estimates of ultimately recoverable resources (URR) of non-renewable energy sources: coal, conventional and unconventional oil, conventional and unconventional gas, and uranium for nuclear fission. There is a large range in the estimates of many of the energy sources, even those that have been utilized for a long time and, as such, should be well understood. If it is assumed that the estimates for each resource are normally distributed, then the total value of ultimately recoverable fossil and fissile energy resources is 70,592 EJ. If, on the other hand, the best fitting distribution from each of the resource estimate populations is used, a the total value is 50,702 EJ, a factor of around 30% smaller. - Highlights: ► Brief introduction to categorization of resources. ► Collated over 380 estimates of ultimately recoverable global resources for all non-renewable energy sources. ► Extensive statistical analysis and distribution fitting conducted. ► Cross-energy source comparison of resource magnitudes.

Starting from the target of the European Union (EU) to use renewable energy in the area that aims a binding target of 20% renewable energy in final energy consumption by 2020, this article illustrates the identification of risks for implementation of wind energy projects in Romania, which could lead to complex technical implications, social and administrative. In specific projects analyzed in this paper were identified critical bottlenecks in the future wind power supply chain and reasonable time periods that may arise. Renewable energy technologies have to face a number of constraints that delayed scaling-up their production process, their transport process, the equipment reliability, etc. so implementing these types of projects requiring complex specialized team, the coordination of which also involve specific risks. The research team applied an analytical risk approach to identify major risks encountered within a wind farm project developed in Romania in isolated regions with different particularities, configured for different geographical areas (hill and mountain locations in Romania). Identification of major risks was based on the conceptual model set up for the entire project implementation process. Throughout this conceptual model there were identified specific constraints of such process. Integration risks were examined by an empirical study based on the method HAZOP (Hazard and Operability). The discussion describes the analysis of our results implementation context of renewable energy projects in Romania and creates a framework for assessing energy supply to any entity from renewable sources.

National Renewable Energy Policy in a Global World

Science.gov (United States)

Jeong, Minji

Increasing trade of renewable energy products has significantly contributed to reducing the costs of renewable energy sources, but at the same time, it has generated protectionist policies, which may negatively affect the trend of the cost reduction. Although a few recent studies examined the rise of renewable energy protectionism and trade disputes, they are limited in addressing the conflict between the original goal of traditional renewable energy policies and the new protectionist policies under the globalized renewable energy industry. To fill this gap, this dissertation explores how the globalized renewable energy industry has changed national renewable energy policies. Through three analyses, three aspects of the globalized renewable energy industry are examined: the rise of multinational corporations, international interactions among actors, and the changes of the global and domestic market conditions. First analysis investigates how multinational renewable energy corporations have affected national policies. A content analysis of the annual reports of 15 solar photovoltaic multinational corporation shows that solar multinationals have been influenced by national policies and have adapted to the changes rather than having attempted to change national policies. Second analysis examines how diverse actors have framed renewable energy trade issues through a network analysis of the Chinese solar panel issue in the United States. The result shows that the Chinese solar panel issue was framed differently from the traditional environmental frame of renewable energy, being dominated by multinational corporations headquartered in other countries. Third analysis explores what has caused the increasing diversity in national renewable energy policies through the case studies of the U.S. and South Korea. The result reveals that the globalization of solar industry has affected the diversification of solar policies in two countries by generating both challenges, which

Reviews and an analysis of the policy support for the stimulation of renewable electricity in the current energy market are presented, and an overview is given of the main new developments influencing the renewable energy market. The report is part of the analysis phase of the project REMAC 2000, which has led to the publication of a roadmap for the acceleration of the RE market. REMAC 2000 aims to promote a sustainable growth of the renewable energy market. For such a sustainable growth, important success factors are not only effectiveness of policy, but also security for investors, which is essential for building up a sector and developing the renewable energy market. Consistency of regulations and policies at different levels and between policy fields form a condition for security, as does the active involvement of market stakeholders. Further, the increasing role of trade within the energy and renewable energy sector leads to a priority for international coherence of policies and markets. To guarantee a sustainable growth of the renewable energy sector, a broad perspective of policy makers and planners is required- to include a long time frame, a comprehensive view of related policy fields and authorities involved, and an orientation that looks beyond national borders

The United Nations Economic Commission for Europe (UNECE) covers a large and diverse region comprising 56 member states. These countries have different energy situations and vary in their potential for and progress in renewable energy and energy efficiency. The present report covers 17 UNECE countries, with the aim of establishing a data baseline and providing a general overview of their renewable energy situations. Over the past decade, the national governments of the selected countries have been working actively to leverage this renewable energy potential. Energy security and access to reliable, affordable, sustainable and modern energy are the key concerns driving renewable energy deployment. These countries require more substantial investment to fully realise its renewable potential and to bring innovative solutions to tackle their energy challenges, such as heating in urban and rural areas. A reliable data baseline is a pre-requisite and an enabler for more investment activity. The UNECE has contributed actively to fulfilling the 17 countries' aspirations in renewable energy by providing them with a platform for collaboration among UNECE member states. In 2014, a UNECE Group of Experts on Renewable Energy was established to step up these efforts. Its mandate is to carry out action-oriented, practical activities to significantly increase the uptake of renewable energy, in line with the United Nations Secretary-General's Sustainable Energy for All (SE4All) initiative. This UNECE Renewable Energy Status Report strives to present analysis of up-to-date data and information on the status of renewable energy and energy efficiency in the selected countries of the UNECE region

Highlights: • Hybrid stand-alone wind–solar–fossil power system is analyzed. • Measurement data are used to evaluate system performance. • The proposed system can generate about 70% from renewables. • Such a hybrid plant is very promising for remote regions in Algeria. - Abstract: There is a great interest in the development of renewable power technologies in Algeria, and more particularly hybrid concept. The present paper has investigated the performance of hybrid PV–Wind–Diesel–Battery configuration based on hourly measurements of Adrar climate (southern Algeria). Data of global solar radiation, ambient temperature and wind speed for a period of one year have been used. Firstly, the proposed hybrid system has been optimized by means of HOMER software. The optimization process has been carried out taking into account renewable resources potential and energy demand; while maximizing renewable electricity use and fuel saving are the purpose. In the second step, a mathematical model has been developed to ensure efficient energy management on the basis of various operation strategies. The analysis has shown that renewable energy system (PV–Wind) is able to supply about 70% of the demand. Wind power has ranked first with 43% of the annual total electricity production followed by diesel generator (with 31%) while the remaining fraction is being to PV panels. In this context, 69% of the fossil fuel can be saved when using the proposed hybrid configuration instead of the diesel generators that are currently installed in most remote regions in Algeria. Such a concept is very promising to meet the focus of renewable energy program announced in 2011.

Renewable energy sources are major components of the strategy to reduce harmful emissions and to replace depleting fossil energy resources. Data from remote sensing can provide information for multicriteria analysis for sources of renewable energy. Advanced land cover quantification makes it possible to search for suitable sites. Multicriteria analysis, together with other data, is used to determine the energy potential and socially acceptability of suggested locations. The described case study is focused on an area of surface coal mines in the northwestern region of the Czech Republic, where the impacts of surface mining and reclamation constitute a dominant force in land cover changes. High resolution satellite images represent the main input datasets for identification of suitable sites. Solar mapping, wind predictions, the location of weirs in watersheds, road maps and demographic information complement the data from remote sensing for multicriteria analysis, which is implemented in a geographic information system (GIS). The input spatial datasets for multicriteria analysis in GIS are reclassified to a common scale and processed with raster algebra tools to identify suitable sites for sources of renewable energy. The selection of suitable sites is limited by the CORINE land cover database to mining and agricultural areas. The case study is focused on long term land cover changes in the 1985-2015 period. Multicriteria analysis based on CORINE data shows moderate changes in mapping of suitable sites for utilization of selected sources of renewable energy in 1990, 2000, 2006 and 2012. The results represent map layers showing the energy potential on a scale of a few preference classes (1-7), where the first class is linked to minimum preference and the last class to maximum preference. The attached histograms show the moderate variability of preference classes due to land cover changes caused by mining activities. The results also show a slight increase in the more

The IRENA Renewable Energy Country Profiles take stock of the latest development of renewable energy in two regions where renewable energy can make a significant contribution to combat climate change and bring modern energy services to everyone: Africa and the Pacific. These two regions are presented separately in this volume and its sister publication. The country profiles combine elements of IRENA analysis with the latest information available from a vast array of sources in order to give a brief yet comprehensive and up-to-date picture of the situation of renewable energy that includes energy supply, electrical capacity, energy access, policies, targets, investment climate, projects and endowment in renewable energy resources. Because of the different timelines of these sources, data presented here refer to years between 2008 and 2012. Data availability also differs from country to country, which makes comparison with a wider regional group possible only for the year for which figures are available for all the members of the group; while this may not be the most recent year, the differences between countries, regions and the world remain striking. The current country profiles are just a starting point; they will be extended upon with new indicators to make them more informative, and maintained as a live product on the IRENA website as a key source of information on renewable energy.

Women are the main producers of energy in developing countries and households are the main users of energy. Because gender roles and traditions have been largely ignored in energy, the global potential for renewable energy has been negatively affected. However, microcredit lending could fund sustainable development technology. This paper argues that renewable energy, gender roles, and microfinancing should be inherent parts of sustainable economic development programs. The relevant activities of pertinent development organisations and potential synergies are briefly described, the plans for the U.S. National Renewable Energy Laboratory to explore the gender issue are summarised, and the evolution of gender and energy as a field is addressed.

The role that renewable energies could play in the world's regional and global energy balances gives rise to varied and often quite different evaluations including almost unbounded ones. Reliable information is still available on the different technologies and their economic costs. But, as the commercial development of these renewables is generally very weak, the arguments for postponing their real possible world and regional impact are frequently confused with short term market type considerations. To overcome that difficulty it is proposed to achieve a comprehensive analysis, region by region, of the actually accessible renewable energies at a given horizon. Then we adopt a methodology as the one employed to derive proven renewable energy reserves from energy renewable resources in which resources are defined by quantitative information on physical potential, when reserves take into account technical and economical accessibility

Renewable energy sources have a small environmental impact and can be easily integrated within existing structures. Moreover, the use of renewable energy sources can contribute to achieve a zero emission of carbon dioxide by 2100, provided an efficient environmental policy during the next 40 years. This includes a correct pricing policy of renewable energy sources with respect to nuclear energy and fossil fuel. The latter energy sources have been favoured in the past. In addition, an open market policy, the restructuring or conversion of existing international energy institutes, and international treaties for the protection of the natural environment are needed in view of achieving the zero carbon dioxide emission objective.

Ambitious Danish and European energy and environment objectives make a point of using renewable energy sources in the electricity supply. Denmark has been leading country in successful development and commercialization of wind turbines and is as yet one of the leading manufacturers of the world. Danish governments have successfully invested a lot in this development. Other countries have spent more money without achieving a similar success. The questions are why things have gone so well in Denmark and if the Danish success can be repeated for other renewable energy technologies. The starting point of this book is that a political decision on subsidizing the developmental process of a specific technology not in itself guarantees that the technology will turn out reliable and efficient enough to compete successfully in a liberalized electricity market. An understanding of this development is necessary in order to affect a technological development. This book goes through the development of different renewable energy technologies and two theories used for discussing the technological development: experience curves and innovation theory. Based on the discussions and a description of causal relations, an analytical model for different phases of renewable energy technologies' developmental progress and technological life cycle is made. The model is used for evaluating the subsidies for chosen renewable technologies in Denmark. With wind energy as example an analysis of what went well or badly, what might be done and which actions might be efficient is made. (BA)

Cost-benefit analysis: introducing energy efficient and renewable energy appliances in Lebanese households

Energy Technology Data Exchange (ETDEWEB)

In Lebanon, neglect of the electricity sector has led to a serious shortage in installed capacity. Recently, the government of Lebanon declared its intention to raise the share of renewable energy (RE) year by year in order to reduce energy consumption. This paper gave a cost-benefit analysis and reviewed the replacement of five major traditional household appliances with their energy efficient (EE) or renewable energy counterparts. This initiative would mostly be felt in three main areas: electricity consumption, consumer costs, and government expenditure. There is a strong possibility that the electricity demand of the 1.2 million Lebanese households can be reduced by introduction of these EE household appliances. Benefits would also accrue to the government in the form of avoided subsidies and reduced need for installed capacity. This paper finds that the benefits to be expected from these policy recommendations largely outweigh the costs.

European Union member states are encouraging renewable energies as alternative energy sources with low environmental impacts, making the renewable energy industry one of Europe's fastest growing sectors. An energy scenario has been defined for the next 20 years and a model has been used to compute the employment impact of this new energy policy. The analysis calculates net employment values which includes direct and indirect impacts and takes into account the loss of jobs in conventional energy sectors. The simulation predicts that energy produced from renewable sources will more than double by 2020. The overall number of net additional jobs predicted to be created in the fifteen countries from 1995 to 2020 is about 900000. This figure includes 515000 jobs that are expected to be created as a consequence of investment in biomass fuel production from agricultural and forestry residues and from energy crops. The analysis foresees that around 20% of the total employment creation will occur in Germany and 15% in France. (A.C.)

Here we investigate the inter-influence of oil prices and renewable energy sources. The non-stationary time series are scrutinized within the Detrended Cross-Correlation Analysis (DCCA) framework, where the resulting DCCA coefficient provides a useful and reliable index to the evaluate the cross correlation between events at the same time instant as well as at a suitably chosen time lags. The analysis is based on the quotient of two successive daily closing oil prices and composite indices of renewable energy sources in USA and Europe in the period 2006-2015, which was subject to several social and economic driving forces, as the increase of social pressure in favor of the use of non-fossil energy sources and the worldwide economic crisis that started in 2008. The DCCA coefficient is evaluated for different window sizes, extracting information for short and long term correlation between the indices. Particularly, strong correlation between the behavior of the two distinct economic sectors are observed for large time intervals during the worst period of the economic crisis (2008-2012), hinting at a very cautious behavior of the economic agents. Before and after this period, the behavior of two economic sectors are overwhelmingly uncorrelated or very weakly correlated. The results reported here may be useful to select proper strategies in future similar scenarios.

The potential for renewable energy use in Canada is examined. It is pointed out that Canada can choose to begin to diversify its energy supply now, moving rapidly and smoothly towards an efficient energy society based on renewable energy sources; or, it can continue on its present course and face the possibility of being forced by necessity to make a later transition to renewable sources, probably with a great deal of economic and political disruption. The handbook begins with a discussion on major issues and options available. This second section deals with the technology, applications, and costs of direct solar energy utilization, solar thermal electricity generation, photovoltaic conversion, wind energy, biomass energy, tidal power, wave energy, ocean thermal energy, geothermal energy, heat pumps, and energy storage. Section three discusses how renewable energy might realistically supply Canada's energy requirements within a reasonable period of time. Some issues on how government, industry, and the individual may become involved to make this happen are suggested. A list of resource people and renewable energy businesses is provided in the last section. A recommended reading list and bibliography complete the handbook. (MCW)

Along with high-speed economic development and increasing energy consumption, the Chinese Government faces a growing pressure to maintain the balance between energy supply and demand. In 2009, China has become both the largest energy consumer and CO 2 emitting country in the world. In this case, the inappropriate energy consumption structure should be changed. As an alternative, a suitable infrastructure for the implementation of renewable energy may serve as a long-term sustainable solution. The perspective of a 100% renewable energy system has been analyzed and discussed in some countries previously. In this process, assessment of domestic renewable energy sources is the first step. Then appropriate methodologies are needed to perform energy system analyses involving the integration of more sustainable strategies. Denmark may serve as an example of how sustainable strategies can be implemented. The Danish system has demonstrated the possibility of converting into a 100% renewable energy system. This paper discusses the perspective of renewable energy in China firstly, and then analyses whether it is suitable to adopt similar methodologies applied in other countries as China approaches a renewable energy system. The conclusion is that China's domestic renewable energy sources are abundant and show the possibility to cover future energy demand; the methodologies used to analyse a 100% renewable energy system are applicable in China. Therefore, proposing an analysis of a 100% renewable energy system in China is not unreasonable. (author)

A Renewable Energy Exporters Network (REEN) has recently been established, following a meeting of renewable energy exporters and government agencies on 30 October 2000. REEN will assist the Australian renewable energy industry to take advantage of the opportunities offered by the burgeoning global market for renewable energy goods and services. Recent estimates of the significant potential global growth is renewable energy demand have reinforced the industry and Government's view that, in the medium to long-term, growth in the Australian renewable energy industry will largely depend on capturing export market share. Expanding the export market was identified as a crucial component in the Renewable Energy Action Agenda, developed jointly by industry and Government and released in June 2000. It was estimated that, for the industry to achieve its vision of sales of $4 billion per year by 2010, exports would need to comprise approximately 50% of the forecast growth in sales. As such, the need for a specific export strategy for the Australian renewable energy industry was recognised in the Action Agenda, and the establishment of the REEN is one of the first initiatives undertaken as part of the Renewable Energy Export Strategy. The REEN comprises approximately 50 export-ready renewable energy companies, the Department of Industry, Science and Resources, Austrade, and Stage Government agencies such as NSW's Sustainable Energy Development Authority. The Export Network will operate electronically, with face-to-face meetings held as appropriate. The Department of Industry, Science and Resources will facilitate the Export Network and has published a website at www.isr.gov.au/industry/reen. The site includes: a members directory; a discussion forum; information on opportunities to showcase Australian renewable; energy products and services; and Iinks to sites containing information that may be useful to renewable energy exporters.

The current Austrian energy system has a renewable energy share of 20% - 11% hydropower and 9 % biomass - of total primary energy consumption. Whereas a possible future introduction of renewable hydrogen must be seen in the context of current energy policies in Austria e.g. increase of energy efficiency and use of renewable energy, reduction of greenhouse gas emissions. The aim of the research project is a life cycle based comparison of energy systems with renewable hydrogen from hydropower, wind, photovoltaic and biomass compared to the direct use of renewable energy for combined heat and power applications and transportation services. In particular this paper focuses on the main question, if renewable energy should be used directly or indirectly via renewable hydrogen. The assessment is based on a life cycle approach to analyse the energy efficiency, the material demand, the greenhouse gas emissions and economic aspects e.g. energy costs and some qualitative aspects e.g. energy service. The overall comparison of the considered energy systems for transportation service and combined heat and electricity application shows, that renewable hydrogen might be beneficial mainly for transportation services, if the electric vehicle will not be further developed to a feasibly wide-spread application for transportation service in future. For combined heat and electricity production there is no advantage of renewable hydrogen versus the direct use of renewable energy. Conclusions for Austria are therefore: 1) renewable hydrogen is an interesting energy carrier and might play an important role in a future sustainable Austrian energy system; 2) renewable hydrogen applications look most promising in the transportation sector; 3) renewable hydrogen applications will be of low importance for combined heat and electricity applications, as existing technologies for direct use of renewable energy for heat and electricity are well developed and very efficient; 4) In a future '100

Full Text Available Environmental friendly renewable energy plays an indispensable role in energy industry development. Foreign direct investment (FDI in advanced renewable energy technology spillover is promising to improve technological capability and promote China’s energy industry performance growth. In this paper, the impacts of FDI renewable energy technology spillover on China’s energy industry performance are analyzed based on theoretical and empirical studies. Firstly, three hypotheses are proposed to illustrate the relationships between FDI renewable energy technology spillover and three energy industry performances including economic, environmental, and innovative performances. To verify the hypotheses, techniques including factor analysis and data envelopment analysis (DEA are employed to quantify the FDI renewable energy technology spillover and the energy industry performance of China, respectively. Furthermore, a panel data regression model is proposed to measure the impacts of FDI renewable energy technology spillover on China’s energy industry performance. Finally, energy industries of 30 different provinces in China based on the yearbook data from 2005 to 2011 are comparatively analyzed for evaluating the impacts through the empirical research. The results demonstrate that FDI renewable energy technology spillover has positive impacts on China’s energy industry performance. It can also be found that the technology spillover effects are more obvious in economic and technological developed regions. Finally, four suggestions are provided to enhance energy industry performance and promote renewable energy technology spillover in China.

Future manufacturing of renewable energy equipment in the United States provides economic development opportunities for state and local communities. However, demand for the equipment is finite, and opportunities are limited. U.S. demand is estimated to drive total annual investments in renewable energy equipment to $14-$20 billion by 2030. Evidence from leading states in renewable energy manufacturing suggests that economic development strategies that target renewable energy sector needs by adapting existing policies attract renewable energy manufacturing more than strategies that create new policies. Literature suggests that the states that are most able to attract direct investment and promote sustained economic development can leverage diverse sets of durable assets—like human capital and modern infrastructure–as well as low barriers to market entry. State marketing strategies for acquiring renewable energy manufacturers are likely best served by an approach that: (1) is multi-faceted and long-term, (2) fits within existing broad-based economic development strategies, (3) includes specific components such as support for renewable energy markets and low barriers to renewable energy deployment, and (4) involves increased differentiation by leveraging existing assets when applicable.

In partnership with the Oregon Military Department, the Department of Energy used the award to assess and evaluate renewable resources in a 2,622-acre location in Lake County, central Oregon, leading to future development of up to 200 MW of solar electricity. The Oregon Military Department (Military) acquired a large parcel of land located in south central Oregon. The land was previously owned by the US Air Force and developed for an Over-the-Horizon Backscatter Radar Transmitter Facility, located about 10 miles east of the town of Christmas Valley. The Military is investigating a number of uses for the site, including Research and Development (R&D) laboratory, emergency response, military operations, developing renewable energy and related educational programs. One of the key potential uses would be for a large scale solar photovoltaic power plant. This is an attractive use because the site has excellent solar exposure; an existing strong electrical interconnection to the power grid; and a secure location at a moderate cost per acre. The project objectives include: 1. Site evaluation 2. Research and Development (R&D) facility analysis 3. Utility interconnection studies and agreements 4. Additional on-site renewable energy resources analysis 5. Community education, outreach and mitigation 6. Renewable energy and emergency readiness training program for veterans

REAL OPTIONS ANALYSIS OF RENEWABLE ENERGY INVESTMENT SCENARIOS IN THE PHILIPPINES

Directory of Open Access Journals (Sweden)

Casper Agaton

2017-12-01

Full Text Available Abstract - With the continuously rising energy demand and much dependence on imported fossil fuels, the Philippines is developing more sustainable sources of energy. Renewable energy seems to be a better alternative solution to meet the country’s energy supply and security concerns. Despite its huge potential, investment in renewable energy sources is challenged with competitive prices of fossil fuels, high start-up cost and lower feed-in tariff rates for renewables. To address these problems, this study aims to analyze energy investment scenarios in the Philippines using real options approach. This compares the attractiveness of investing in renewable energy over continuing to use coal for electricity generation under uncertainties in coal prices, investments cost, electricity prices, growth of investment in renewables, and imposing carbon tax for using fossil fuels.

Full Text Available Energy modelling work in Ireland to date has mainly taken place at a national level. A regional modelling approach is necessary however, for Ireland to reach the ambitious targets for renewable energy and emissions reduction. This paper explores the usefulness of the energy modelling tool EnergyPLAN in investigating the energy system of the South West Region of Ireland. This paper estimates a 10.5% current renewable energy share of energy use, with 40% renewable electricity. We build and assess a reference scenario and three renewable energy scenarios from a technological and resources perspective. The results show that sufficient resources are available for the South West Region energy system to become 100% renewable and quantifies the land-use implications. Moreover, EnergyPLAN can be a useful tool in exploring different technical solutions. However, thorough investigations of as many alternatives as possible, is necessary before major investments are made in a future energy system.

Analysis of renewable energy projects' implementation in Russia

Ratner, S. V.; Nizhegorodtsev, R. M.

2017-06-01

With the enactment in 2013 of a renewable energy scheme by contracting qualified power generation facilities working on renewable energy sources (RES), the process of construction and connection of such facilities to the Federal Grid Company has intensified in Russia. In 2013-2015, 93 projects of solar, wind, and small hydropower energy were selected on the basis of competitive bidding in the country with the purpose of subsequent support. Despite some technical and organizational problems and a time delay of some RES projects, in 2014-2015 five solar generating facilities with total capacity of 50 MW were commissioned, including 30 MW in Orenburg oblast. However, the proportion of successful projects is low and amounts to approximately 30% of the total number of announced projects. The purpose of this paper is to analyze the experience of implementation of renewable energy projects that passed through a competitive selection and gained the right to get a partial compensation for the construction and commissioning costs of RES generating facilities in the electric power wholesale market zone. The informational background for the study is corporate reports of project promoters, analytical and information materials of the Association NP Market Council, and legal documents for the development of renewable energy. The methodological base of the study is a theory of learning curves that assumes that cost savings in the production of high-tech products depends on the production growth rate (economy of scale) and gaining manufacturing experience (learning by doing). The study has identified factors that have a positive and a negative impact on the implementation of RES projects. Improvement of promotion measures in the renewable energy development in Russia corresponding to the current socio-economic situation is proposed.

Dessus, B; Devin, B; Pharabod, F

1991-07-01

A comprehensive analysis, region by region, of the actually accessible renewable energies at a given horizon, is presented. The same methodology as the one employed to derive ``proven fossil energy reserves`` from ``energy resources`` is adopted, in which resources are defined by quantitative information on physical potential, while reserves take into account technical and economical accessibility. As renewable resources are fluctuating with time and are diluted in space and not readily transportable or storeable, it is necessary to consider the presence of populations or activities near enough to be able to profit by these diluted and volatile energies.

China's renewable energy policy: Commitments and challenges

International Nuclear Information System (INIS)

Wang Feng; Yin Haitao; Li Shoude

2010-01-01

The passing of the Renewable Energy Law (REL) in 2005 demonstrated China's commitment to renewable energy development. In the 3 years after the REL, China's renewable electricity capacity grew rapidly. From 2006 to 2008, China's wind capacity installation more than doubled every year for 3 years in a row. However, three facts prevent us from being optimistic about China's renewable electricity future. First, considered as a share of total capacity, renewable electricity capacity is decreasing instead of increasing. This is due simply to the rapid growth of fossil fuel capacity. Second, a significant amount of renewable generation capacity is wasted because it is not connected to the electricity grid. Finally, renewable electricity plants are running at a low level of efficiency. Based on an in-depth analysis of China's existing renewable energy policy, we suggest that these challenges should be dealt with by introducing a market-based mandatory renewable portfolio requirement coupled with strong regulatory monitoring of grid enterprises.

In 2005, the National Renewable Energy Laboratory (NREL) completed an assessment of the potential for solar and wind energy development on National Forest System (NFS) public lands managed by the US Department of Agriculture, U.S. Forest Service (USFS). This report provides an update of the analysis in the NREL report, and extends the analysis with additional siting factors for solar and wind energy. It also expands the scope to biomass and geothermal energy resources. Hydropower is acknowledged as another major renewable energy source on NFS lands; however, it was not analyzed in this project primarily because of the substantially different analysis that would be needed to identify suitable locations. Details about each renewable energy production technology included in the study are provided following the report introduction, including how each resource is converted to electrical power, and examples of existing power plants. The analysis approach was to use current and available Geographic Information System (GIS) data to map the distribution of the subject renewable energy resources, major siting factors, and NFS lands. For each major category of renewable energy power production, a set of siting factors were determined, including minimum levels for the renewable energy resources, and details for each of the other siting factors. Phase 1 of the analysis focused on replicating and updating the 2005 NREL analysis, and Phase 2 introduced additional siting factors and energy resources. Source data were converted to a cell-based format that helped create composite maps of locations meeting all the siting criteria. Acreages and potential power production levels for NFS units were tabulated and are presented throughout this report and the accompanying files. NFS units in the southwest United States were found to have the most potentially suitable land for concentrating solar power (CSP), especially in Arizona and New Mexico. In total, about 136,032 acres of NFS lands

Renewable energy in Europe

Europe's increasing demand for energy and its environmental preoccupations are creating a favourable environment for the development of renewable energy sources. This article stated that although many European countries have adopted voluntary policies since the 1990s to increase the use of renewable energy sources, they have not been developed in an equal or consistent manner. A table was included to show the consumption of renewable energies by country; the percentage of renewable energies in 1995 as compared to 2006; and the consumption of primary energy resources. Combined, Germany, Spain and Denmark produce 75 per cent of wind energy in Europe, while 75 per cent of Europe's hydroelectricity is produced in Norway, Sweden, France, Italy, Austria and Switzerland. Germany has also made significant contributions in developing biomass energy. The article emphasized that the development of renewable energy sources is limited by the fact that it cannot keep up with growing energy demands. In addition, renewable energies cannot yet replace all fossil fuel consumption in Europe because of the variation in development from one country to another. 1 ref., 2 tabs., 4 figs.

Two of the major challenges the U.S. energy sector faces are greenhouse gas emissions and oil that is both imported and potentially reaching a peak (the point at which maximum extraction is reached). Interest in development of both renewable and nuclear energy has been strong because both have potential for overcoming these challenges. Research in both energy sources is ongoing, but relatively little research has focused on the potential benefits of combining nuclear and renewable energy. In September 2011, the Joint Institute for Strategic Energy Analysis (JISEA) convened the Nuclear and Renewable Energy Synergies Workshop at the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) to identify potential synergies and strategic leveraging opportunities between nuclear energy and renewable energy. Industry, government, and academic thought leaders gathered to identify potential broad categories of synergies and brainstorm topic areas for additional analysis and research and development (R&D). This report records the proceedings and outcomes of the workshop.

The thesis presents various possibilities for renewable energy in Norway. The wind power would give a practical and economic alternative. The external costs for the wind power would be moderate. In chapter 3 the utility cost analysis for renewable alternatives are studied relative to the macroeconomic efficiency. Some methodical problems and how these analyses are used are reviewed. In the practical utility cost analyses wind power is studied relative to gas power which is the non-renewable alternative present in Norway today. A qualitative part is included. It is not possible to determine whether wind power is preferable to gas power in the macroeconomic perspective. Wind power would be the choice if high environmental and CO2 cleaning costs are expected. The first conclusion to be drawn is that it is difficult to decide whether wind power is the best solution based on cost benefit analysis. However, the alternative seems to be quite robust in the analysis. Due to the central position the energy supplies have in the society this business should be heavily regulated. The sector is also overtaxed as a reduction in consumption is desired. The analysis shows that the system does not function perfectly. The thesis surveys various measures for improving the renewable energy supply and focuses on the wind power. A model for and analysis of the measures are carried out and resulted in a second conclusion. The measures have various properties as to the influence on the market. A subsidy is a fine measure for stimulation production of green power while a tax reduces efficiently the production of black power. A system with green licenses in combination with a subsidy and a tax would be preferable as to increasing the part of renewable energy of the total production. It is therefore necessary to have clearly defined goals and use suitable measures for achieving them. The costs of wind power is falling and it would therefore soon be macroeconomic profitable. It is also

2007-02-15

Today, the analysis of renewable energy places the emphasis on the technological and economic attributes with social and environmental impact assessment providing for a rather static, narrow frame of analysis. The participation and response of social actors and other stakeholders is usually of a traditional type, with consultation documents and public meetings, collection of complaints and suggestion schemes. This often encourages parochialism and an over-concentration on relatively trivial issues. It is, therefore, imperative to establish a new participatory planning platform to incorporate the wider socio-economic aspects of renewable energy systems and to provide for an operational analytical decomposition of them. In this work the issue of decomposition analysis is clarified, and a new agenda for the societal and technological decomposition analysis of renewable energy systems is developed. A case study is disclosed to present the relevance of the established platform for integrated (renewable) energy systems planning. Innovative aspects comprise of the simultaneous inclusion of decision analysis and social acceptance methods and tools in concert with the related public participation techniques. (author)

IRENA Renewable Energy Country Profiles take stock of the latest developments in the field of renewables at country level around the world. Each profile combines analysis by IRENA's specialists with the latest available country data and additional information from a wide array of sources. The resulting reports provide a brief yet comprehensive picture of the situation with regard to renewable energy, including energy supply, electrical generation and grid capacity, and access. Energy policies, targets and projects are also considered, along with each country's investment climate and endowment with renewable energy resources. The energy statistics presented here span the period from 2009 until 2012, reflecting varying timelines in the source material. Since data availability differs from country to country, wider regional comparisons are possible only for the latest year with figures available for every country included. Despite the time lag in some cases, the evident differences and disparities between countries and regions around the world remain striking. The current package of country profiles is just a starting point. The geographic scope will continue to expand, and existing profiles will be enhanced with new indicators, with the whole series maintained as a live product on the IRENA website (www.irena.org)

Community energy planning in Canada. The role of renewable energy

International Nuclear Information System (INIS)

St Denis, Genevieve; Parker, Paul

2009-01-01

An emerging trend in Canada is the creation of community energy plans, where decisions that used to be left to regional level energy agencies or private individuals are now being considered at the community level. A desire to reduce greenhouse gas emissions and to become more energy self-sufficient is driving this change. Theoretically, local level management is desirable because it achieves these goals through improvements in the three areas of energy efficiency, energy conservation and switching to renewable energy sources. The analysis of 10 of the first community energy plans in Canadian communities, ranging in population size from 500 to one million, finds that communities are choosing policies and programs centred on increasing energy efficiency and conservation while renewable energy receives much less attention. Municipal operations were called upon to set higher targets than the general community. Communities that recognized the substantial potential of renewable energy often focused on technologies that the municipal sector could implement, such as bio-fuels for their transportation fleet. Wind, passive solar design, solar photovoltaics and solar thermal options were only recommended in a few cases. Overall, only one of the five larger communities (Calgary) recommended implementing multiple renewable energy technologies while three of the five smaller communities proposed multiple renewable energy sources. The implication is that smaller and more remote communities may be the most willing to lead in the planned introduction of renewable energy systems. (author)

There exists a large potential for renewable energy technologies in South Africa and despite the fact that rapid growth of the application of renewable energy takes place in many parts of the world, the current installed renewable capacity in South Africa is negligible. The objective of this study is to address this gap by analysing ways to accelerate the market penetration of renewable energy technologies in South Africa. The activities undertaken in this study comprise two major components: a thorough analysis of South Africa's specific constraints and barriers to renewable energy implementation, and a review of the lessons learnt from Member States of the European Union (EU) on the promotion of renewable energy development. The focus of the study was restricted to the analysis of electricity generating technologies, in particular solar energy, biomass, wind power and mini-hydro renewable energy technologies. Recommendations to stimulate the market penetration of renewable energy technologies in South Africa are formulated. They are structured in: actions to enhance the policy framework for renewable power generation, actions to enhance the policy framework for off-grid renewable energy, and recommendations to stimulate renewable energy project development. 44 refs

Chen, T.-Y.; Yu, Oliver S.; Hsu, George Jyh-yih; Hsu, Fang-Ming; Sung, W.-N.

2009-01-01

This paper presents the results of a case study of applying a systematic and proven process of technology portfolio planning with the use of scenario analysis to renewable energy developments in Taiwan. The planning process starts with decision values of technology development based on a survey of society leaders. It then generates, based on expert opinions and literature search, a set of major technology alternatives, which in this study include: wind energy, photovoltaic, bio-energy, solar thermal power, ocean energy, and geothermal energy. Through a committee of technical experts with diversified professional backgrounds, the process in this study next constructs three scenarios ('Season in the Sun', 'More Desire than Energy', and 'Castle in the Air') to encompass future uncertainties in the relationships between the technology alternatives and the decision values. Finally, through a second committee of professionals, the process assesses the importance and risks of these alternative technologies and develops a general strategic plan for the renewable energy technology portfolio that is responsive and robust for the future scenarios. The most important contributions of this paper are the clear description of the systematic process of technology portfolio planning and scenario analysis, the detailed demonstration of their application through a case study on the renewable energy development in Taiwan, and the valuable results and insights gained from the application.

Because of the different timelines of these sources, data presented here refer to years between 2009 and 2012. Data availability also differs from country to country, which makes comparison with a wider regional group possible only for the year for which figures are available for all the members of the group; while this may not be the most recent year, the differences between countries, regions and the world remain striking. The current country profiles are just a starting point; they will be extended upon with new indicators to make them more informative, and maintained as a live product on the IRENA website as a key source of information on renewable energy.

THE RENEWABLE ENERGY PRODUCTION-ECONOMIC DEVELOPMENT NEXUS

Full Text Available As renewable energy requirements increases, its relation with development is controversial. In this study, by taking human development index for development level, the relationship between renewable electricity net generation values and development has been searched with panel analysis. Study covers two different time periods: 1980-2010 with 5 year data to analyze long term effects and 2005-2010 yearly data for short term effects. Unlike previous studies, energy generation has been taken into consideration for it is thought to be more related with economic development. It is found that in the long run economic development will be leading to renewable energy production, while in the short run there exists a bidirectional causal relationship between renewable energy production and economic development. In addition, the causal relationship between economic development and renewable energy production varies both in the long run and in the short run due to human development level of the countries.

An analysis of Grenada's power sector and energy resources: a role for renewable energy technologies?

International Nuclear Information System (INIS)

Wiesser, D.

2004-01-01

Presently, Grenada's power sector is fully dependent on fossil fuel imports for meeting the country's electricity demand. Electric utilities in Small Island Developing States (SIDS), in general, face high cost of electricity generation due to diseconomies of scale in production, consumption and logistical aspects. Grenada's private power monopoly is no exception and the high cost of import dependent electricity generation places an increasing burden on economic development. In light of rapid technological and economic improvement of renewable energy technologies (RETs), the country's abundant sources of renewable energy should be harnessed. Benefits are envisaged to include lower electricity cost, better environmental performance and a safer and diversified supply of energy. However, barriers for shifting power production towards meaningful contributions from RETs exist, both in government and industry. This work analyses important economic interactions between the power sector and economic development, bringing to attention the importance of power sector reform. Further, present problems of integrating RETs into the grid, ranging from technical and regulatory issues to shareholder interest are investigated. A summary and analysis of past research into renewable sources of energy (RES) underscore the potential for power production from RETs in Grenada. (author)

What drives renewable energy development?

International Nuclear Information System (INIS)

Alagappan, L.; Orans, R.; Woo, C.K.

2011-01-01

This viewpoint reviews renewable energy development in 14 markets that differ in market structure (restructured vs. not restructured), use of feed-in-tariff (FIT) (yes vs. no), transmission planning (anticipatory vs. reactive), and transmission interconnection cost allocated to a renewable generator (high vs. low). We find that market restructuring is not a primary driver of renewable energy development. Renewable generation has the highest percent of total installed capacity in markets that use a FIT, employ anticipatory transmission planning, and have loads or end-users paying for most, if not all, of the transmission interconnection costs. In contrast, renewable developers have been less successful in markets that do not use a FIT, employ reactive transmission planning, and have generators paying for most, if not all, of the transmission interconnection costs. While these policies can lead to higher penetration of renewable energy in the short run, their high cost to ratepayers can threaten the economic sustainability of renewable energy in the long-run. - Highlights: → Market structure seems to have little effect on renewable energy development. → Renewable energy development is more successful in markets that use a FIT. → Anticipatory transmission planning aids renewable energy development. → Low interconnection costs for developers also aids renewable energy development.

With limited indigenous conventional energy resources, Taiwan imports over 99% of its energy supply from foreign countries, mostly from the Middle East. Developing independent renewable energy resources is thus of priority concern for the Taiwanese government. A medium subtropical island surrounded by the Pacific Ocean, Taiwan has enormous potential to develop various renewable energies, such as solar energy, biomass energy, wind power, geothermal energy, hydropower, etc. However, owing to the importance of conventional fossil energy in generating exceptionally cheap electricity, renewable energy has not yet fully developed in Taiwan, resulting from a lack of market competition. Consequently, numerous promotional and subsidy programs have recently been proclaimed by the Taiwanese government, focused on the development of various renewables. This study reviews the achievements, polices and future plans in this area. (author)

Full Text Available  Energy is the backbone of any development in any State. Renewable Energy (wind, solar and biomass appears currently as a major strategic energy source for a sustainable development particularly for developing or under developing societies. Use of renewable Energy will challenge major technological changes, by achieving energy production and saving. In particular by replacing fossil fuel, a significant cut of environmental impact and green house gas emission (GHG could be achieved. In addition Renewable Energy could offer a sustainable development for different societies particularly those in rural area (e.g. desert or isolated islands. The significant technical renewable energy tool developments in developed States could be much easier to be transferred to or copied in developing States .

Effect of wind energy system performance on optimal renewable energy model - an analysis

Iniyan, S.; Jagadeesan, T.R.

1998-01-01

The Optimal Renewable Energy Model (OREM) has been developed to determine the optimum level of renewable energy sources utilisation in India for the year 2020-21. The model aims at minimising cost/efficiency ratio and determines the optimum allocation of different renewable energy sources for various end-uses. The extent of social acceptance level, potential limit, demand and reliability will decide the renewable energy distribution pattern and are hence used as constraints in the model. In this paper, the performance and reliability of wind energy system and its effects on OREM model has been analysed. The demonstration windfarm (4 MW) which is situated in Muppandal, a village in the southern part of India, has been selected for the study. The windfarm has 20 wind turbine machines of 200 KW capacity . The average technical availability, real availability and capacity factor have been analysed from 1991 to 1995 and they are found to be 94.1%, 76.4% and 25.5% respectively. The reliability factor of wind energy systems is found to be 0.5 at 10,000 hours. The OREM model is analysed considering the above said factors for wind energy system, solar energy system and biomass energy systems. The model selects wind energy for pumping end-use to an extent of 0.3153 x10 15 KJ. (Author)

Renewable energy is the effective solution for the harmonious coexistence of human and environment as well as for the sustainable development. Marine renewable energy as one of the renewable energies, potentially offer fewer environmental risks and thus community acceptance than other renewable energy developments. Government support is the key and initial power for developing marine renewable energy. To promote the development and utilization of marine renewable energy, the Chinese government has established the special funding plan for marine renewable energy, and released “the 13th Five-years Plan (2016-2020) for marine renewable energy”. This paper describes the mechanisms established by the marine renewable Energy policy in China, and provides a comparative analysis of the Chinese marine renewable energy policy framework. We provides some policy recommendations for future development of marine renewable energy in China.

Technologies using renewable energy sources are receiving increasing interest from both public authorities and power producing companies, mainly because of the environmental advantages they procure in comparison with conventional energy sources. These technologies can be substitution for conventional energy sources and limit damage to the environment. Furthermore, several of the renewable energy technologies satisfy an increasing political goal of self-sufficiency within energy production. The subject of this thesis is promotion of renewable technologies. The primary goal is to increase understanding on how technological development takes place, and establish a theoretical framework that can assist in the construction of policy strategies including instruments for promotion of renewable energy technologies. Technological development is analysed by through quantitative and qualitative methods. (BA)

The analysis of different global energy scenarios in part I of the report confirms that the exploitation of energy efficiency potentials and the use of renewable energies play a key role in reaching global CO2 reduction targets. An assessment on the basis of a broad literature research in part II shows that the technical potentials of renewable energy technologies are a multiple of today's global final energy consumption. The analysis of cost estimates for renewable electricity generation technologies and even long term cost projections across the key studies in part III demonstrates that assumptions are in reasonable agreement. In part IV it is shown that by implementing technical potentials for energy efficiency improvements in demand and supply sectors by 2050 can be limited to 48% of primary energy supply in IEA's ''Energy Technology Perspectives'' baseline scenario. It was found that a large potential for cost-effective measures exists, equivalent to around 55-60% of energy savings of all included efficiency measures (part V). The results of the analysis on behavioural changes in part VI show that behavioural dimensions are not sufficiently included in energy scenarios. Accordingly major research challenges are revealed.

Priority to renewable energies - on the amendment to the renewable energies act

International Nuclear Information System (INIS)

Heller, W.

2003-01-01

The Federal Ministry for the Environment, which has been the competent authority for renewable energies since the 2002 federal election, has presented draft legislation on the accelerated development of renewable energies in the electricity sector. This is to reduce, through internalization, the costs to the national economy arising from power supply, to conserve nature and the environment, avoid conflicts over fossil energy resources, and promote the advanced development of renewable energy technologies. Emphasis is put solely on protection of the climate and of the environment. The way towards sustainable energy supply by taking into account ecological, economic and social aspects is abandoned. The funding rates laid down in legislation are not going to offer major incentives for further plant improvement by technological development. The quantitative goals of this draft legislation onesidedly aimed at electricity production are doubtful. Renewable energies are hardly the right way to replace nuclear power plants operated in the baseload mode. What is missing in the draft legislation, though it would be urgently needed, is a clear time limit on the eligibility of renewable energy plants for subsidizing, as this would counteract the impression of permanent subsidizing.

Using a combination of thematic analysis and studio-based planning proposals in West Greenland, this paper proposes that there is more than one interpretation of resilience in renewable energy planning. All energy transitions, from one system to another, are protracted and unpredictable......, and the transition to a renewable energy system is proving no exception. Such a transition is particularly amplified in the context of Greenland – a country undergoing rapid transformation in many fields, including energy. Resilience theory offers an approach for how to plan for this energy transition, but how...... to translate resilience theory into planning practices remains underdeveloped. The paper begins by outlining some of the challenges in planning a transition to renewable energy, and sketching Greenland’s energy landscape. It then discusses the key characteristics of resilience thinking, before proposing...

The Directive 2009/28/EC on the promotion of the use of energy from renewable sources (RES) sets the overall target to reach 20% renewable energy in gross final energy consumption in 2020. This target is broken down into binding individual Member State targets. Reaching these targets will require a huge mobilization of investments in renewable energies in the coming decade. In order to improve financing and coordination with a view to the achievement of the 20 % target, Article 23 (7) of the Directive requires the Commission to present an analysis and action plan with a view to: (a) The better use of structural funds and framework programmes; (b) The better and increased use of funds from the European Investment Bank and other public finance institutions; (c) Better access to risk capital; (d) The better coordination of Community and national funding and other forms of support; (e) The better coordination in support of renewable energy initiatives whose success depends on action by actors in several Member States. This report presents the results of the title project. The study provides an up to date and thorough assessment of the costs of renewable energy and the support and financing instruments available for renewable energy R and D, demonstration projects and large-scale deployment. This includes details of each Member State's expenditure (via grants, support schemes, loans etc.) and use of Community funds, including loans of the EIB (European Investment Bank) and the EBRD (European Bank for Reconstruction and Development). It also explores the possible instruments for use in the future and constraints in the capital market, which hinder the development of renewable energy. Finally, it develops recommendations for improving financing and support instruments, improving the sector's access to capital, and closing the financing gap for reaching the 2020 targets.

Renewable energy sources (RES) are low-carbon energies available right within our borders, and as such can be of great value in addressing the challenges of climate change and energy security. In 2014, renewable energies accounted for 14.6% of France's gross final energy consumption. The French Energy Transition Act for Green Growth sets renewables targets of 23% and 32% as a share of gross final energy consumption by 2020 and 2030, respectively. However, renewable energies are still more costly than conventional energies. A significant share of this additional cost is borne by energy consumers, particularly in the form of energy taxation and biofuels blending obligations. Public aid is also provided to support heat production from renewable energy sources (RES-H). The two most significant aids available today are the Energy Transition Tax Credit (CITE) and the Heat Fund. Comparing the various types of renewable energies shows sharp disparities in terms of the cost of avoiding one tonne of CO 2 , which ranges from euros 59 to more than euros 500 for electricity production it follows that the cost of the energy transition is likely to vary significantly depending on which renewable energy sources are pushed to the fore. The combustion of biomass for heat production appears to offer an economically efficient way to reduce CO 2 emissions. Of the various renewable technologies available for the production of electricity (with the exception of hydropower, which was excluded from the scope of this study), onshore wind power is the least costly

Full Text Available Reliable estimation of surface sensible and latent heat flux is the most important process to appraise energy and mass exchange among atmosphere and biosphere. In this study the surface energy fluxes were measured over an irrigated orange orchard during 2005-2008 monitoring periods using a Surface Renewal- Energy Balance approach. The experimental area is located in a representative orchard growing area of eastern Sicily (Italy. The performance of Surface Renewal (SR analysis for estimating sensible heat flux (H was analysed and evaluated in terms of correlation with H fluxes from the eddy covariance (EC method. Study revealed that the mean available energy (RN- G and latent heat flux (LE were of about 300 W m-2 and 237 W m-2, respectively, during dry periods and unstable-case atmospheric conditions. The estimated crop coefficient Kc values for the orchard crop averaged close to 0.80, which is considerably higher than previous FAO studies that found the value to be 0.65 for citrus with 70% of ground cover. The intercepted photosynthetically active radiation (LI PAR by the crop was measured and relationships between LAI and crop coefficient (Kc were established.

Over the last decade Germany has boosted renewable energy in power production by means of massive subsidies. The flip side are very high electricity prices which raises concerns that the transition cost towards a renewable energy system will be mainly borne by poor households. In this paper, we combine computable general equilibrium and microsimulation analysis to investigate the cost-effectiveness and incidence of Germany's renewable energy promotion. We find that the regressive effects of renewable energy promotion could be ameliorated by alternative subsidy financing mechanisms which achieve the same level of electricity generation from renewable energy sources.

Renewable energy outlook in Iran and World's energy structure

Limited fossil fuel resources and environmental impact of energy production technologies causing Global Warming have encouraged wide spread used of renewable energies. This article reviews the characteristics of renewable energy sources as well as their status within IR of Iran and pro-countries. According to the mentioned Information and Status, currently 22% of world electricity is produced through conversion of various renewable energies and expected to grow even further. This trend has been a main factor in reduction of end-used renewable energy prices. Consideration of social and environmental costs of fossil fuel use will help to reveal compatibility of renewable energies. Utilization of renewable energy potentials apart from proven environmental advantages and job creation effects may conserve country's conventional fossil fuel resources. In general, growth of renewable energy in a country is direct result of existing energy policies with respect to increasing the share of clean energies in the energy basket. Nevertheless in Iran yearly demand hikes for energy and considering the fact the fossil fuel reservoirs are limited, utilization of renewable energy potentials is inevitable

With the objective of development of the energy mix for the Douai area, a first document reports a study which aimed at examining present modalities of energy supplies and potentials of development of renewable energies on the territory, in order to elaborate a mix energy strategy. This report presents the methodology adopted to acquire data, outlines the necessity to reduce consumptions, comments the distribution of renewable energy production in 2011 and predictions by 2020-2050. It proposes a detailed analysis of mobilisable renewable energies (solar photovoltaic and thermal, wood, geothermal, wind, biogas, waste water heat recovery, micro-hydroelectricity, fatal energies, co-generation). It also discusses the impact on local development in terms of energy dependence, air pollution and financial consequences, and also how to integrate this energetic development into land planning documents. Besides this document, contributions presented during a meeting on renewable energies as a factor of local development are proposed. While addressing the same issues as above, these contributions propose an overview of mobilisable renewable energy sources for the area, outline the interest for local communities to develop their potential in renewable energies, discuss the usefulness of planning documents to promote and ease this development, and discuss how to obtain maximum financial and social fallout from small and large projects of renewable energies

The renewable energy market in Australia

International Nuclear Information System (INIS)

2002-01-01

Australia is committed to an 8 per cent reduction in its emissions of greenhouse gases above 1990 levels as a result of the Kyoto Protocol for the period 2008-2012. At present, the emissions stand at 17.4 per cent above 1990 levels. Total electrical power in Australia resulting from renewable energy is in the order of 10.5 per cent. A mandatory renewable energy target of 9500 gigawatt hour (GWh) of extra renewable energy is to be produced annually by 2010, under the Renewable Energy (Electricity) Act. An emissions trading system has been implemented, involving one renewable energy certificate (REC) created for each megawatt hour of renewable energy generated. A significant expansion of the demand for renewable energy is expected in Australia over the next ten years, according to the Australian Greenhouse Office. Increased opportunities for local and international firms operating in the field of renewable energy are being created by the Australian government through initiatives such as the Renewable Energy Commercialization Program, and the Renewable Remote Power Generation Program. Solar, biomass, and wind power are comprised in the wealth of renewable energy resources in Australia. The market remains largely undeveloped. Firms from the United States and the European Union are the leading exporters of renewable energy technology to Australia. Public utilities and independent power producers having entered the deregulated electricity market are the consumers of renewable energy technology and services. A country with minimal duties in most cases, Australia has much in common with Canada, including similar regulatory and legal systems. Australia applies a 10 per cent goods and services tax, which would apply to Canadian exports. It was advised to consult the Australian Customs Service for additional information concerning duties that might be applicable to the renewable energy industry. 28 refs., 3 tabs

2016-01-01

This report is one of a series of reports that Idaho National Laboratory and National Renewable Energy Laboratory are producing to investigate the technical and economic aspects of nuclear-renewable hybrid energy systems (N-R HESs). Previous reports provided results of an analysis of two N-R HES scenarios. This report builds that analysis with a Texas-synthetic gasoline scenario providing the basis in which the N-R HES sells heat directly to an industrial customer. Subsystems were included that convert electricity to heat, thus allowing the renewable energy subsystem to generate heat and benefit from that revenue stream. Nuclear and renewable energy sources are important to consider in the energy sector's evolution because both are considered to be clean and non-carbon-emitting energy sources.

The U.S. Department of Energy (DOE) recognizes the need to transform the energy infrastructure of the U.S. and elsewhere to systems that can drastically reduce environmental impacts in an efficient and economically viable manner while utilizing both hydrocarbon resources and clean energy generation sources. Thus, DOE is supporting research and development that could lead to more efficient utilization of clean energy generation sources, including renewable and nuclear options. A concept being advanced by the DOE Offices of Nuclear Energy (NE) and Energy Efficiency and Renewable Energy (EERE) is tighter coupling of nuclear and renewable energy sources in a manner that produces new energy currency for the combined electricity grid, industrial manufacturing, and the transportation energy sectors. This integration concept has been referred to as a “hybrid system” that is capable of providing the right type of energy, at the right time, in the right place. At the direction of DOE-NE and DOE-EERE leadership, project leads at Idaho National Laboratory (INL), National Renewable Energy Laboratory (NREL) and Massachusetts Institute of Technology (MIT) have identified and engaged stakeholders in discussing integrated energy systems that would optimize renewable and nuclear energy integration on a region-by-region basis. Subsequent work will entail conduct of technical, economic, environmental and socio-political evaluations of the leading integrated system options based on a set of criteria established with stakeholder input.

The EurObserv'ER policy profiles give a snapshot of the renewable energy policy in the EU Member States. With Ireland's current 'trajectory' of renewable energy growth, it is likely to slightly fall short of its 2020 nationally binding renewable energy target. Ireland initiated a 'moratorium' on its REFIT (Renewable Energy Feed-in Tariff) support scheme in December 2015, with the aim of introducing a revised scheme in 2017 in line with market developments. Grants and tax relief remain in place for renewable heat promotion. An Offshore Renewable Energy Development Plan (OREDP) was introduced in 2014, which sets out Government policy in relation to the sustainable development of Ireland's abundant offshore renewable energy resource

Brown, B.

2005-01-01

Approximately 7 per cent of Prince Edward Island's (PEI) energy supply is from renewable sources, acquired mainly from biomass. Wind power accounts for 0.5 per cent of electricity production. This paper discussed issues concerning renewable energy developments in PEI, with particular reference to the PEI Renewable Energy Act as well as the PEI energy framework and renewable energy strategy, which was the result of public consultation sessions held in 2003. The results of these sessions indicated that greater development of indigenous renewable energy resources was desired, particularly in wind power. It was also stated that the government should help to advance renewable energy development in the province. Several development opportunities were highlighted, including: wind; biodiesel; ethanol; biomass; bio-gas; and small-scale hydro. The advantages of wind power were reviewed and wind data was presented. The economic and community benefits of renewable energy include local price stability, development opportunities, diversity of fuel type and security of supply. It was noted that renewable energy fully complemented the energy goals of the PEI government. Several strategies were discussed towards the development of renewable energy, including feasibility studies in biogas and biomass generation. The PEI government's commitment towards developing a regulatory framework acknowledging environmental sustainability was re-stated. Objectives include the promotion of renewable energy sources through the establishment of a Renewable Portfolio Standard for electricity; improvements in the economics of small-scale electricity production from renewable resources through the introduction of net metering; decreases in peak demand; enablement of green credits; the designation of areas for large-scale wind developments; and provision of guaranteed prices paid to producers for medium and large-scale renewable energy generators through feed-in tariffs. tabs, figs

Renewable energy projects are increasingly confronted by local opposition, which delays and sometimes even prevents their implementation. This reflects the frequent gap between support for the general idea of renewables as a strategy for reducing carbon emissions, and acceptance of renewable energy...... installations in the local landscape. A number of countries have introduced financial incentives to promote community acceptance. The tool box of incentives is still limited but in recent years it has been expanded to address local concerns. Certain general characteristics can be identified, suggesting...... that there are at least three distinct categories of incentives: individual compensation, community benefits and ownership measures. Local opposition must be approached with caution, as financial incentives to promote local acceptance can be seen as buying consent or even ‘bribery’, stirring up further opposition....

If one compares the progress in research and development of renewable energy applications with the finding which has been granted to these activities during the 23 years after the first oil shock, one cannot but be very impressed. It is indicated in this paper hoe comprehensive the potential of renewable energy is. One should take into account that the methods described form a broad interdisciplinary field in contrast to fossil and nuclear technologies. From technical point of view the present and future energy demand can be met by the broad spectrum of renewable energies in combination with energy conservation. Many of these techniques are already economically competitive: solar architecture, wind energy, hydropower, low temperature heat production, photovoltaic for remote areas, various types of biomass application, geothermal energy although not exactly renewable. The future of renewable energies will depend on opening markets for these techniques

On 27 March 2013, the European Commission published its first Renewable Energy Progress Report under the framework of the 2009 Renewable Energy Directive. Since the adoption of this directive and the introduction of legally binding renewable energy targets, most Member States experienced significant growth in renewable energy consumption. 2010 figures indicate that the EU as a whole is on its trajectory towards the 2020 targets with a renewable energy share of 12.7%. Moreover, in 2010 the majority of Member States already reached their 2011/2012 interim targets set in the Directive. However, as the trajectory grows steeper towards the end, more efforts will still be needed from the Member States in order to reach the 2020 targets. With regard to the EU biofuels and bioliquids sustainability criteria, Member States' implementation of the biofuels scheme is considered too slow. In accordance with the reporting requirements set out in the 2009 Directive on Renewable Energy, every two years the European Commission publishes a Renewable Energy Progress Report. The report assesses Member States' progress in the promotion and use of renewable energy along the trajectory towards the 2020 renewable energy targets. The report also describes the overall renewable energy policy developments in each Member State and their compliance with the measures outlined in the Directive and the National Renewable Energy Action Plans. Moreover, in accordance with the Directive, it reports on the sustainability of biofuels and bioliquids consumed in the EU and the impacts of this consumption. A consortium led by Ecofys was contracted by the European Commission to perform support activities concerning the assessment of progress in renewable energy and sustainability of biofuels.

Renewable energies for power generation

International Nuclear Information System (INIS)

Freris, L.; Infield, D.

2009-01-01

Power generation from renewable energy sources is different from power generation from classical energies (nuclear, thermal..). Therefore, the integration into the grid of the electricity supplied by renewable sources requires a deep thinking. The reason is that these power sources are controlled by variable elements, like wind, water and sun, which condition production. This book deals with the following aspects in detail: characteristics of classical and intermittent generators; grid balancing between supply and demand; conversion methods of renewable energies into electricity; power systems; privatizing of power generation and birth of new markets, in particular the 'green' power market; development of renewable energies thanks to technical advances. It gives a comprehensive overview of the present day available renewable energy sources for power generation. (J.S.)

While the share of renewable energy, especially wind power, increases in the energy mix, the risk of temporary energy shortage increases as well. Thus, it is important to understand consumers' preference for the renewable energy towards the continuous growing renewable energy society. We use a discrete choice experiment to infer consumers' preferences when the share of renewable energy increases. The study results indicate that consumers are generally willing to pay extra for an increasing share of renewable energy, but the renewable energy should come from a mixture of renewable energy sources. We also found that consumers prefer to trade with their current supplier rather than another well-known supplier. This study contributes to the energy portfolio theories and the theory of energy diversification in a consumer perspective. The managerial implications of this study are also discussed. - Highlights: • This paper investigates consumer preference for electricity when the share of renewable energy increases in the energy mix. • A total of 7084 choice sets were completed in the survey. • Consumer prefers a high percentage of mixed renewable energy at an affordable price level when the share of renewable increases. • Current electricity supplier was found to be the most favorable supplier for consumers. • Results had implications on energy regulators/policy makers, electricity retailers and renewable energy investors.

Renewable energy policy. Into the mainstream

Renewable energy today is at a critical stage of development: renewable technologies are maturing, and costs for some technologies are in the competitive range. Beyond the energy they produce, renewable energy technologies offer a variety of other benefits towards the achievement of sustainable development goals. This promise has led to all IEA governments to support their greater development. But, while renewables markets are growing strongly, additional steps must be taken to accelerate the achievement of sustainable, large-scale markets. This report by the IEA's Renewable Energy Working Party outlines those steps, and the benefits of moving renewable energy into the mainstream

The County of Somerset, New Jersey, through the Somerset County Improvement Authority (SCIA), applied Federal funding through the U.S. Department of Energy to will apply project funds to buy-down the capital costs of equipment associated with the installation of solar photovoltaic (PV) systems at two sites owned by the County. This Renewable Energy Initiative allows the County to take advantage of clean renewable energy, without any adverse debt impacts, and at a price that results in operating budget savings beyond what is presently available in the marketplace. This project addressed the objectives of the Office of Energy Efficiency and Renewable Energy by making the acquisition of renewable energy more affordable for the County, thereby, encouraging other counties and local units to develop similar programs and increase the deployment of solar energy technologies. The two sites that were funded by the DOE grant are part of a much larger, ambitious, and unique renewable energy project, described in the next section.

Matzen, Michael; Alhajji, Mahdi; Demirel, Yaşar

2015-01-01

This study is for the technoeconomic analysis of an integral facility consisting of wind energy-based electrolytic hydrogen production, bioethanol-based carbon dioxide capture and compression, and direct methanol synthesis. ASPEN Plus was used to simulate the facility producing 97.01 mt (metric tons) methanol/day using 138.37 mt CO_2/day and 18.56 mt H_2/day. A discounted cash flow diagram for the integral facility is used for the economic analysis at various hydrogen production costs and methanol selling prices. The feasibility analysis is based on a multi-criteria decision matrix consisting of economic and sustainability indicators comparing renewable and non-renewable methanol productions. The overall energy efficiency for the renewable methanol is around 58%. Fixation of carbon reduces the CO_2 equivalent emission by around −1.05 CO_2e/kg methanol. The electrolytic hydrogen production cost is the largest contributor to the economics of the integral facility. The feasibility analysis based on multi-criteria shows that renewable methanol production may be feasible. - Highlights: • We simulate renewable methanol production from wind-based hydrogen and CO_2_. • Methanol production can fix 1.05 kg CO_2/kg methanol with an energy efficiency of 58%. • Economic and sustainability metrics are estimated for the integral facility. • We introduce a decision matrix with both economic and sustainability indicators. • Renewable methanol may be feasible versus conventional fossil fuel-based methanol.

Full Text Available China is the most densely populated country in the world with high rate of economic growth resulting in higher demand for energy resources and in strive to guarantee stable supply of these resources. Chinese annual GDP growth in 2012 and 2013 was down to 7.7% comparing to 10% in 2000-2011 [7]. In 2012 and 2013 economic growth stumbled because of slowdown in manufacturing and exports, taking into account that Chinese government was eager to cut inflation and excessive investments in some segments of the market. Speaking about energy sector Chinese government is aimed at promotion of market-based pricing systems, activities for advanced energy efficiency and higher competition between energy companies, and increased investment in renewable energy resources. Considering renewables as one of many ways to diversify energy supplies, lower dependence on coal and improve environmental situation Chinese government actively supports and develops programs aimed at support of renewable energy industry in China. Chinese economic development is tightly attached to five-year plans. It seems important to mention the fact that main energy goals for current 12-th "five-year plan" are to achieve 15% renewables consumption and CO2 sequestration up to 40-45% by2020 in order to lower dependency on coal and improve environmental situation. As a result of Chinese state policy to develop renewables China achieved certain results in wind energy, helioenergetics, hydroenergetics and energy from waste recycling.

It is usually mentioned that renewable energy sources (RES) have a large potential to contribute to the sustainable development of specific territories by providing them with a wide variety of socioeconomic benefits, including diversification of energy supply, enhanced regional and rural development opportunities, creation of a domestic industry and employment opportunities. The analysis of these benefits has usually been too general (i.e., mostly at the national level) and a focus on the regional and especially the local level has been lacking. This paper empirically analyses those benefits, by applying a conceptual and methodological framework previously developed by the authors to three renewable energy technologies in three different places in Spain. With the help of case studies, the paper shows that the contribution of RES to the economic and social dimensions of sustainable development might be significant. Particularly important is employment creation in these areas. Although, in absolute terms, the number of jobs created may not be high, it may be so with respect to the existing jobs in the areas considered. Socioeconomic benefits depend on several factors, and not only on the type of renewable energy, as has usually been mentioned. The specific socioeconomic features of the territories, including the productive structure of the area, the relationships between the stakeholders and the involvement of the local actors in the renewable energy project may play a relevant role in this regard. Furthermore, other local (socioeconomic) sustainability aspects beyond employment creation should be considered. (author)

Liu, Jun; Zhang, Jinfang; Tian, Feng; Mi, Zhe

2017-01-01

The accommodation and curtailment of renewable energy in northeast China have attracted much attention with the rapid growth of wind and solar power generation. Large amount of wind power has been curtailed or abandoned in northeast China due to several reasons, such as, the redundancy of power supplies, inadequate power demands, imperfect power structure with less flexibility and limited cross-regional transmission capacity. In this paper, we use multi-area production simulation to analyse the accommodation of renewable energy in northeast China by 2020. Furthermore, we suggest the measures that could be adopted in generation, grid and load side to reduce curtailment of renewables.

Garcia, Humberto E.; Mohanty, Amit; Lin, Wen-Chiao; Cherry, Robert S.

2013-01-01

Dynamic analysis of HES (hybrid energy systems) under flexible operation and variable renewable generation is considered in this two-part communication to better understand various challenges and opportunities associated with the high system variability arising from the integration of renewable energy into the power grid. Advanced HES solutions are investigated in which multiple forms of energy commodities, such as electricity and chemical products, may be exchanged. In particular, a comparative dynamic cost analysis is conducted in this part two of the communication to determine best HES options. The cost function includes a set of metrics for computing fixed costs, such as fixed operations and maintenance and overnight capital costs, and also variable operational costs, such as cost of operational variability, variable operations and maintenance cost, and cost of environmental impact, together with revenues. Assuming natural gas, coal, and nuclear as primary heat sources, preliminary results identify the level of renewable penetration at which a given advanced HES option (e.g., a nuclear hybrid) becomes increasingly more economical than a traditional electricity-only generation solution. Conditions are also revealed under which carbon resources may be better utilized as carbon sources for chemical production rather than as combustion material for electricity generation. - Highlights: ► Dynamic analysis of HES to investigate challenges related to renewable penetration. ► Evaluation of dynamic synergies among HES constituents on system performance. ► Comparison of traditional versus advanced HES candidates. ► Dynamic cost analysis of HES candidates to investigate their economic viability. ► Identification of conditions under which an energy commodity may be best utilized

Modeling renewable energy company risk

International Nuclear Information System (INIS)

Sadorsky, Perry

2012-01-01

The renewable energy sector is one of the fastest growing components of the energy industry and along with this increased demand for renewable energy there has been an increase in investing and financing activities. The tradeoff between risk and return in the renewable energy sector is, however, precarious. Renewable energy companies are often among the riskiest types of companies to invest in and for this reason it is necessary to have a good understanding of the risk factors. This paper uses a variable beta model to investigate the determinants of renewable energy company risk. The empirical results show that company sales growth has a negative impact on company risk while oil price increases have a positive impact on company risk. When oil price returns are positive and moderate, increases in sales growth can offset the impact of oil price returns and this leads to lower systematic risk.

Harvesting energy: Place and local entrepreneurship in community-based renewable energy transition

International Nuclear Information System (INIS)

Süsser, Diana; Döring, Martin; Ratter, Beate M.W.

2017-01-01

Transition towards a renewable energy supply initiates a physical (re)shaping of places and a social transformation of communities into renewable energy communities. Although socio-cultural challenges of energy transition have been recognised (), understandings about socio-geographic places of energy transition and their underlying social processes and structures are insufficiently studied and often remain underestimated. To close this gap, we theoretically and empirically analysed the multifaceted interplay between place, local entrepreneurship and ‘community renewable energy’. Our study is based on an analysis of regional documents and policy reports, and on qualitative interviews undertaken with inhabitants in the case-study municipality of Reußenköge (Germany). Our findings reveal two important aspects: Firstly, people's individual and shared place meanings which materialised in social, physical, historical and climate-related place-attachments and meanings of contested and innovative place are important ingredients bearing an impact on processes of adopting or rejecting renewables. Secondly, differentiated characteristics of entrepreneurs, namely grounded, collaborative, innovative, change-making, economic, communicating, networking and political aspects, appeared to be relevant for the acceptance and support in community-based renewable energy projects. Our findings reveal that energy policies, funding schemes and administrative structures should recognise local socio-geographic important elements in the context of a sustained and decentralised energy transition. - Highlights: • Places are resources of experiences, creativity and innovation for community renewables. • Energy policies should recognise place-based approaches to grassroots community energy actions. • A located view of multifaceted entrepreneurship is relevant to support community renewable energy. • Supportive funding schemes should empower community-based concepts.

In this report, different long-term evolutions of the Belgian future energy system are drafted, analysed and evaluated. All evolutions are designed to meet the requirement of a 100% renewable based national energy system by 2050. For this purpose, a baseline is developed which depicts an energy system without the stringent renewables' requirement. Next, different trajectories are sketched that lead up to a 100% renewable coverage in 2050. The trajectories show that it is feasible to combine economic growth and comfort with far going deployment of renewable energy sources, provided a number of key options and effective policies and measures are being implemented. These options were deducted from several discussions with stakeholders via an open dialogue process, as well as with national experts, and finally, were presented to the Steering committee. The analysis leads to the undeniable observation that drastic changes in a multitude of areas throughout society are required to obtain the desired level of renewable energy penetration in 2050, but also that such a transition can be realised through various sectoral, technology and inter-temporal choices. In other words, this study describes a vast number of different trajectories leading to a 100% renewable energy system in Belgium in the long term, as well as their socio-economic impacts.

An energy resource that is renewed by nature and whose supply is not affected by the rate of consumption is often termed as renewable energy. The need to search for renewable, alternate and non-polluting sources of energy assumes top priority for self-reliance in the regional energy supply. This demands an estimation of available energy resources spatially to evolve better management strategies for ensuring sustainability of resources. The spatial mapping of availability and demand of energy resources would help in the integrated regional energy planning through an appropriate energy supply-demand matching. This paper discusses the application of Geographical Information System (GIS) to map the renewable energy potential talukwise in Karnataka State, India. Taluk is an administrative division in the federal set-up in India to implement developmental programmes like dissemination of biogas, improved stoves, etc. Hence, this paper focuses talukwise mapping of renewable energy (solar, wind, bioenergy and small hydroenergy) potential for Karnataka using GIS. GIS helps in spatial and temporal analyses of the resources and demand and also aids as Decision Support System while implementing location-specific renewable energy technologies. Regions suitable for tapping solar energy are mapped based on global solar radiation data, which provides a picture of the potential. Coastal taluks in Uttara Kannada have higher global solar radiation during summer (6.31 kWh/m{sup 2}), monsoon (4.16 kWh/m{sup 2}) and winter (5.48 kWh/m{sup 2}). Mapping of regions suitable for tapping wind energy has been done based on wind velocity data, and it shows that Chikkodi taluk, Belgaum district, has higher potential during summer (6.06 m/s), monsoon (8.27 m/s) and winter (5.19 m/s). Mysore district has the maximum number of small hydropower plants with a capacity of 36 MW.

Promoting renewable energy through capacity markets: An analysis of the Russian support scheme

International Nuclear Information System (INIS)

Boute, Anatole

2012-01-01

Most existing support schemes aim to stimulate the deployment of renewable energy sources in the electricity sector on the basis of the electricity output (MW h) of renewable energy installations. Support is anchored in the electricity commodity market. In contrast to this established approach, Russia intends to promote renewable energy through the capacity market. The idea is to remunerate investors for the installed capacity (MW) of their installations, in particular for the availability of their installations to produce electricity. This article argues that, contrary to the implicit consensus, a capacity-based approach to supporting renewable energy can provide an alternative to the current output-based schemes. Capacity-based schemes limit the incentive that the operators of renewable energy installations currently have under output-based schemes to deliver electricity to the grid even in periods of low demand. These schemes also provide investors with a more predictable income flow. However, to be successful, the regulation of capacity supply – currently designed for flexible power plants – needs to accommodate the specific production patterns of variable renewable energy installations. This paper examines ways to overcome this challenge in Russia and provides more general conclusions on the complex interaction between capacity markets and renewable energy investments.

Renewable energy have a prominent place among the solutions to combat global warming, but its potential is still untapped in Brazil. Without long-term policies with clear rules, you can not attract entrepreneurs and ensure stability of operation of this market. The main tools of government to promote renewable energy generation have not been efficient - the Incentive Program for Alternative Sources of Energy (Proinfa) was implemented in 2002 but put into operation just over two thirds of the energy proposal. The low success rate in repeated auctions focused on renewable energy. The objective of this paper is to discuss the prospects of the expansion of electricity generation by renewable energies in Brazil and some fundamental requirements for effective structuring of this market in the country. This argument is supported by the analysis of the proposed mechanisms used internationally and in the country, under a new law for renewable energies. As a practical demonstration of the analysis, we present a simulation of conditions of formation of the final price of renewable resources in different conditions as varied market rate of return, cost of transmission, and sale of carbon credits.

Contrary to popular belief, renewables primarily biomass and hydropower currently supply about 20% of the world's energy. Biomass alone meets 35% of developing countries total energy needs, though often not in a manner that is renewable or sustainable in the long term. Steady advances have been made since the mid-seventies in an array of new energy technologies that will be needed if the world is to greatly increase its reliance on renewable resources. Indeed many of the machines and processes that could provide energy in a renewable energy based economy are now almost economically competitive with fossil fuels. Further cost reductions are expected in the next decade, as these technologies continue to improve through R and D efforts. After a period of neglected in the eighties, many governments are now supporting new energy technologies more effectively, which may signal the beginning of a renewable energy boom in the years ahead.

Marques, Antonio C.; Fuinhas, Jose A.; Pires Manso, J.R.

2010-01-01

Despite the increasing amount of literature available on renewable energy, the empirical analysis about drivers promoting renewables remains scarce. We have analyzed those drivers for European Countries. Over an extended period of time (1990-2006) we used panel data techniques, namely the fixed effects vector decomposition. The results suggest that both the lobby of the traditional energy sources (oil, coal, and natural gas) and CO 2 emissions restrain renewable deployment. The objective of reducing energy dependency appears to stimulate renewable energy use. Our results robustly support the EU decision to create a directive promoting the use of renewable sources (Directive 2001/77/EC). We also offer suggestions with regards to the design of appropriate policies towards renewable energy deployment.

Despite various policies, renewable energy resources have not been developed in Malaysia. This study investigates the factors that influence renewable energy technology acceptance in Peninsular Malaysia and attempts to show the impact of cost and knowledge on the perceived ease of use and perceived usefulness of renewable energy technology. The results show that cost of renewable energy has an indirect effect on attitudes towards using renewable energy through the associated impact on the perceived ease of use and perceived usefulness. The results also indicate that public knowledge in Peninsular Malaysia does not affect perceived ease of use, although the positive impact of knowledge on perceived usefulness is supported. Furthermore, our results show that the current business environment in Peninsular Malaysia does not support the adoption of renewable energy technology, and thus, renewable energy technology is not commercially viable in Peninsular Malaysia. Additionally, the population of Peninsular Malaysia associates the use of renewable energy with a high level of effort and therefore has a negative attitude towards the use of renewable energy technology. There is, therefore, a definite need to pay more attention to the role of public perception and awareness in the successes and failures of renewable energy policy. - Highlights: • Public acceptance is an essential element in the diffusion of renewable energy. • Perceived ease of use and perceived usefulness affect intention to use renewables. • It is important to reduce the cost of renewable energy, particularly for end users. • Renewable energy policies should address issues of public perception and awareness.

Recently, the importance of renewable energy sources has increased significantly as climate change has become an important long term threat to global ecosystems and the world economy. In the face of increased concern about climate change and high fossil fuel costs together with a reduction in the primary energy sources such as oil, natural gas and coal, alternative energy sources (renewables) are increasingly needed to respond to the threat of climate change and growing energy demand in the world. Recent developments in Turkey, such as the liberalization of the electricity market and improvements in the renewable legislations, have accelerated the growth process and investment opportunities in the field of renewable energy. Turkey′s naturally endowed potential for renewables, such as solar, geothermal and wind, also accompanied these developments and attracted world attention to this market. In Turkey, renewable energy sources have gained great importance in the last decades due to growing energy demand and incentive policies which foster the utilization of renewable energy sources. This study aims to explore the availability and potential of renewable energy sources in Turkey and discuss the government policies and economic aspects. - highlights: • Turkey′s potential for renewable energy has attracted world attention. • Turkey has specific energy objectives in promoting renewable energy. • This paper evaluates recent incentives for renewable energy in Turkey. • Incentives in Turkey have led to more investment in renewable energy generation

A 100% renewable energy system in the year 2050: The case of Macedonia

International Nuclear Information System (INIS)

Ćosić, Boris; Krajačić, Goran; Duić, Neven

2012-01-01

The most important problems the energy sector faces in Macedonia are an unfavourable energy mix with a high prevalence of lignite, a strong dependence on energy import, poor condition of the energy system and inefficiency in energy production and use. This paper investigates the prospects for realization of the 100% renewable energy system in Macedonia by making use of the EnergyPLAN model. Analysis was conducted for two renewable scenarios designed for the years 2030 and 2050. First scenario, the 50% renewable energy system, has been created for the year 2030 and represents the first step towards the 100% renewable energy future of Macedonia. The second scenario has been designed for the 100% renewable energy system based only on the renewable energy sources (RES) in the year 2050. Special attention in the design of these systems has been given to intermittent RES and to storage technologies. The analysis reveals that at the moment the 50% renewable energy system seems much more likely than the 100% renewable energy system, but with additional energy efficiency measures, which will lead to a decrease of consumption and with installation of new generation capacities this goal can be easily achieved.

A hypothetical fuel-energy system based on indigenous, renewable resources to achieve energy self-sufficiency in Hawaii by the end of the 21st century is presented. In this case study, renewable resources would provide sufficient energy for a projected total energy consumption of approximately 335 x 10{sup 6}GJ from approximately 15 GWe of installed capacity in the year 2100. The renewable fuel-energy system would feature methanol-from-biomass to meet liquid fuel requirements for surface transportation and for the industrial, commercial, and residential sectors; hydrogen via electrolysis in liquid form for air transportation and as a gaseous fuel for industrial purposes; and electricity generated from geothermal, ocean thermal, wind, and photovoltaic sources for all power applications. A green economic analysis indicates that between the years 1987 and 2100 the switch to this hypothetical renewable fuel-energy system would require expenditures of approximately $400 billion (1986 U.S. dollars), representing a saving of approximately $200 billion over continuing a business-as-usual fuel-energy system based on imported fossil fuels.

Wagland, S T; Dudley, R; Naftaly, M; Longhurst, P J

2013-11-01

Two novel techniques are presented in this study which together aim to provide a system able to determine the renewable energy potential of mixed waste materials. An image analysis tool was applied to two waste samples prepared using known quantities of source-segregated recyclable materials. The technique was used to determine the composition of the wastes, where through the use of waste component properties the biogenic content of the samples was calculated. The percentage renewable energy determined by image analysis for each sample was accurate to within 5% of the actual values calculated. Microwave-based multiple-point imaging (AutoHarvest) was used to demonstrate the ability of such a technique to determine the moisture content of mixed samples. This proof-of-concept experiment was shown to produce moisture measurement accurate to within 10%. Overall, the image analysis tool was able to determine the renewable energy potential of the mixed samples, and the AutoHarvest should enable the net calorific value calculations through the provision of moisture content measurements. The proposed system is suitable for combustion facilities, and enables the operator to understand the renewable energy potential of the waste prior to combustion. Copyright © 2013 Elsevier Ltd.

A methodology for analysis of impacts of grid integration of renewable energy

International Nuclear Information System (INIS)

George, Mel; Banerjee, Rangan

2011-01-01

Present electricity grids are predominantly thermal (coal, gas) and hydro based. Conventional power planning involves hydro-thermal scheduling and merit order dispatch. In the future, modern renewables (hydro, solar and biomass) are likely to have a significant share in the power sector. This paper presents a method to analyse the impacts of renewables in the electricity grid. A load duration curve based approach has been developed. Renewable energy sources have been treated as negative loads to obtain a modified load duration curve from which capacity savings in terms of base and peak load generation can be computed. The methodology is illustrated for solar, wind and biomass power for Tamil Nadu (a state in India). The trade-offs and interaction between renewable sources are analysed. The impacts on capacity savings by varying the wind regime have also been shown. Scenarios for 2021-22 have been constructed to illustrate the methodology proposed. This technique can be useful for power planners for an analysis of renewables in future electricity grids. - Research highlights: → A new method to analyse impacts of renewables in the electricity grid. → Effects of wind, solar PV and biomass power on load duration curve and capacity savings are shown. → Illustration of intermittent renewables and their interplay for sites in India and the UK. → Future scenarios constructed for generation expansion planning with higher levels of renewable.

Renewable energy islands in Europe

Energy Technology Data Exchange (ETDEWEB)

Oestergaard, Iben [ed.

1998-12-31

This publication includes a compiled presentation of various aspects concerning the possible transformation of some European islands into renewable energy communities and these projects were presented by a selection of pioneer islands at the first European Seminar on Renewable Energy Islands, held on the Danish island of Samsoee, 29-30 June 1998. This issue has increased in importance with the presentation of the ambitious EU-White Paper: `Energy for the future: Renewable Sources of Energy` which was adopted in 1998. One of the key elements of the strategy for an accelerated implementation of renewable energy is to transform 100 localities within Europe into communities which are to be 100% self-sufficient with renewable energy before 2010. In line with this strategy, the Danish Government appointed the island of Samsoe towards the end of 1997 to be the first `official` Danish, renewable energy island. This is to serve as a demonstration project for other local communities, both in Denmark as well as in the rest Europe. Gothland, Madeira, Canary Islands, Cape Verde, Arki, Crete, Minorca and Orkney Islands were represented. Environmental advantages of wind, solar and wave power for distant island communities were indicated. Serious savings would be achieved by limitation of fossil fuel import and utilization of local resources. (EG)

Design, analysis, operation, and advanced control of hybrid renewable energy systems

Science.gov (United States)

Whiteman, Zachary S.

Because using non-renewable energy systems (e.g., coal-powered co-generation power plants) to generate electricity is an unsustainable, environmentally hazardous practice, it is important to develop cost-effective and reliable renewable energy systems, such as photovoltaics (PVs), wind turbines (WTs), and fuel cells (FCs). Non-renewable energy systems, however, are currently less expensive than individual renewable energy systems (IRESs). Furthermore, IRESs based on intermittent natural resources (e.g., solar irradiance and wind) are incapable of meeting continuous energy demands. Such shortcomings can be mitigated by judiciously combining two or more complementary IRESs to form a hybrid renewable energy system (HRES). Although previous research efforts focused on the design, operation, and control of HRESs has proven useful, no prior HRES research endeavor has taken a systematic and comprehensive approach towards establishing guidelines by which HRESs should be designed, operated, and controlled. The overall goal of this dissertation, therefore, is to establish the principles governing the design, operation, and control of HRESs resulting in cost-effective and reliable energy solutions for stationary and mobile applications. To achieve this goal, we developed and demonstrated four separate HRES principles. Rational selection of HRES type: HRES components and their sizes should be rationally selected using knowledge of component costs, availability of renewable energy resources, and expected power demands of the application. HRES design: by default, the components of a HRES should be arranged in parallel for increased efficiency and reliability. However, a series HRES design may be preferred depending on the operational considerations of the HRES components. HRES control strategy selection: the choice of HRES control strategy depends on the dynamics of HRES components, their operational considerations, and the practical limitations of the HRES end-use.

Renewable energy - an attractive marketing proposition

2001-01-01

The Global Utilities arm of international business consultants PriceWaterhouseCoopers (PWC) has provided a unique insight into the investment plans of Australian utilities regarding renewable energy. PWC has released the findings of a survey of electricity generators and retailers that neatly illustrates the risks and opportunities facing corporations liable under the mandatory renewable energy targets (MRET). Probably the most revealing finding of the PWC report- 'The Future of Australian Renewable Energy' was that the majority of respondents have not yet formulated a comprehensive renewable energy strategy aimed at meeting their obligations under MRET, or maximising the benefit of renewable energy certificates (RECs) produced. Notably, the majority of those surveyed believed that the strongest incentives for investing in new renewable energy generation was the company's 'green image'. In contrast investment characteristics such as low risk returns, the achievement of cost efficiencies or attractive revenue streams were not critical reasons for investing in renewable generation

Renewable energy rebound effect?: Estimating the impact of state renewable energy financial incentives on residential electricity consumption

Science.gov (United States)

Stephenson, Beth A.

Climate change is a well-documented phenomenon. If left unchecked greenhouse gas emissions will continue global surface warming, likely leading to severe and irreversible impacts. Generating renewable energy has become an increasingly salient topic in energy policy as it may mitigate the impact of climate change. State renewable energy financial incentives have been in place since the mid-1970s in some states and over 40 states have adopted one or more incentives at some point since then. Using multivariate linear and fixed effects regression for the years 2002 through 2012, I estimate the relationship between state renewable energy financial incentives and residential electricity consumption, along with the associated policy implications. My hypothesis is that a renewable energy rebound effect is present; therefore, states with renewable energy financial incentives have a higher rate of residential electricity consumption. I find a renewable energy rebound effect is present in varying degrees for each model, but the results do not definitively indicate how particular incentives influence consumer behavior. States should use caution when adopting and keeping renewable energy financial incentives as this may increase consumption in the short-term. The long-term impact is unclear, making it worthwhile for policymakers to continue studying the potential for renewable energy financial incentives to alter consumer behavior.

New and renewable energies. Stakes, driving forces and perspectives of the renewable energies market

International Nuclear Information System (INIS)

2000-09-01

New and renewable energies (hydro-power, wind-power, solar, biomass, biogas, geothermal and fuel cells) are progressively entering the industrialization phase (except for hydro-power which is already largely developed). Thus they are no more considered as solutions for utopian ecologists but have reached the status of alternative technologies. This study takes stock of the following questions: what are the applications of renewable energies, what is their stage of development and their potential with respect to fossil fuels, what are their perspectives of development, and what are the strategies developed by the actors of the sector? The main stakes of the renewable energy sector are: fulfilling the increasing power needs (in particular with the wind and solar power in isolated areas), improving the competitiveness (reduction of the investment costs), developing financial incentives (tax relief, financial helps, eco-taxes..), participating to the reduction of pollutant emissions. The renewable energy sector is progressively structuring and profits by the increasing implication of major energy actors, such as the oil companies. The behaviour and strategy of 14 major actors of the renewable energy sector is also analyzed. (J.S.)

Improving cost-effectiveness and mitigating risks of renewable energy requirements

Science.gov (United States)

Griffin, James P.

Policy makers at the federal and state levels of government are debating actions to reduce U.S. greenhouse gas emissions and dependence on oil as an energy source. Several concerns drive this debate: sharp rises in energy prices, increasing unease about the risks of climate change, energy security, and interest in expanding the domestic renewable energy industry. Renewable energy requirements are frequently proposed to address these concerns, and are currently in place, in various forms, at the federal and state levels of government. These policies specify that a certain portion of the energy supply come from renewable energy sources. This dissertation focuses on a specific proposal, known as 25 X 25, which requires 25% of electricity and motor vehicle transportation fuels supplied to U.S. consumers to come from renewable energy sources, such as wind power and ethanol, by 2025. This dissertation builds on prior energy policy analysis, and more specifically analyses of renewable energy requirements, by assessing the social welfare implications of a 25 x 25 policy and applying new methods of uncertainty analysis to multiple policy options decision makers can use to implement the policy. These methods identify policy options that can improve the cost-effectiveness and reduce the risks of renewable energy requirements. While the dissertation focuses on a specific policy, the research methods and findings are applicable to other renewable energy requirement policies. In the dissertation, I analyze six strategies for implementing a 25 x 25 policy across several hundred scenarios that represent plausible futures for uncertainties in energy markets, such as renewable energy costs, energy demand, and fossil fuel prices. The strategies vary in the availability of resources that qualify towards the policy requirement and the use of a "safety valve" that allows refiners and utilities to pay a constant fee after renewable energy costs reach a predetermined threshold.

The contribution of renewable energy in the Netherlands to 2020

International Nuclear Information System (INIS)

Ybema, J.R.; Kroon, P.; De Lange, T.J.; Ruijg, G.J.

1999-09-01

The Dutch Government aims to increase the contribution of renewable energy from a current share of slightly more than 1% of total energy use to 10% by the year 2020. Several policy measures have already been implemented in order to achieve this ambitious target. Currently, the Government wishes an updated insight whether the 10% target is within reach with the existing mix of policy instruments or not. The present analysis of the future contribution of renewables took into account the latest developments with respect to technological innovation, cost reduction, fuel price developments and liberalisation of energy markets. In this study a scenario-based approach is applied to analyse these questions. An existing energy scenario was taken for which the fossil energy price projections have been adjusted downward in accordance with recent insight. All renewable options have been analysed and for several renewable technologies new cost projections have been made based on learning curve analysis. In a scenario with a best estimate for the future cost of renewables and at a constant 15$/bbl (30 Dutch guilder per barrel) oil price, the share of renewables reaches 3.7% of projected total energy use in 2010 and 5.4% in 2020. Relatively large contributions are projected for wind energy, waste and biomass and import of renewable energy. A second request of the Government was to give insight in the approximate additional societal cost to achieve 10% renewable energy. The societal cost of renewables contribution in the 'best guess' is estimated at 1.2 billion Dutch guilders in the year 2020. A mix of policy measures to reach the 10% renewables target in 2020, mainly consisting of more financial incentives, will result in societal cost amounting to 2.5 billion guilders in 2020. Thus, the additional societal cost to meet the 10% target will amount to approximately 1.3 billion guilders in the year 2020. 114 refs

In recent years, the Economic Community of West African States (ECOWAS), comprising 15 Member States, it has emerged as one of the most active and dynamic regional economic communities on the African continent. Expanding access to modern, reliable, and affordable energy services is a key priority, prompting inter-state cooperation in crucial areas including capacity building, policy development and implementation, and investment. Recognising the critical role that sustainable energy plays in catalysing social, economic, and industrial development across the region, ECOWAS Member States formally inaugurated the ECOWAS Centre for Renewable Energy and Energy Efficiency (ECREEE) in 2010 to 'contribute to the sustainable economic, social and environmental development of West Africa by improving access to modern, reliable and affordable energy services, energy security and reduction of energy related externalities'. Drawing on data from the ECOWAS Observatory for Renewable Energy and Energy Efficiency (ECOWREX) and a network of contributors and researchers across the region, the ECOWAS Renewable Energy and Energy Efficiency Status Report supports ECREEE's efforts to increase the deployment of renewable energy and energy efficiency in West Africa by providing a comprehensive regional review of renewable energy and energy efficiency developments, evolving policy landscapes, market trends and related activities, investments in renewable energy and off-grid energy solutions, and the crucial nexus between energy access and gender

Renewable energy and macroeconomic efficiency of OECD and non-OECD economies

International Nuclear Information System (INIS)

Chien, Taichen; Hu, Jin-Li

2007-01-01

This article analyzes the effects of renewable energy on the technical efficiency of 45 economies during the 2001-2002 period through data envelopment analysis (DEA). In our DEA model, labor, capital stock, and energy consumption are the three inputs and real GDP is the single output. Increasing the use of renewable energy improves an economy's technical efficiency. Conversely, increasing the input of traditional energy decreases technical efficiency. Compared to non-OECD economies, OECD economies have higher technical efficiency and a higher share of geothermal, solar, tide, and wind fuels in renewable energy. However, non-OECD economies have a higher share of renewable energy in their total energy supply than OECD economies

It comments the application of the Energy multi-year plan (PPE), evokes the content of a report by the French Court of Auditors about costs and means of implementation of transition (with notably the issue of maintenance of nuclear plants). It also shows that European Union is not a leader in renewable energies any more, that some European countries are changing sides, that figures and trends must be carefully compared with those in the field of fossil and nuclear energies, that all energies are not all the same, that jobs and system integration are also important, that investments and attractiveness of countries in renewable energies must be assessed, and that a mobilisation on small scale and consumer-based renewable energies is required. Ten recommendations are made for France to support the EU leadership development

Full Text Available Energy justice is increasingly being used as a framework to conceptualize the impacts of energy decision making in more holistic ways and to consider the social implications in terms of existing ethical values. Similarly, renewable energy technologies are increasingly being promoted for their environmental and social benefits. However, little work has been done to systematically examine the extent to which, in what ways and in what contexts, renewable energy technologies can contribute to achieving energy justice. This paper assesses the potential of renewable electricity technologies to address energy justice in various global contexts via a systematic review of existing studies analyzed in terms of the principles and dimensions of energy justice. Based on publications including peer reviewed academic literature, books, and in some cases reports by government or international organizations, we assess renewable electricity technologies in both grid integrated and off-grid use contexts. We conduct our investigation through the rubric of the affirmative and prohibitive principles of energy justice and in terms of its temporal, geographic, socio-political, economic, and technological dimensions. Renewable electricity technology development has and continue to have different impacts in different social contexts, and by considering the different impacts explicitly across global contexts, including differences between rural and urban contexts, this paper contributes to identifying and understanding how, in what ways, and in what particular conditions and circumstances renewable electricity technologies may correspond with or work to promote energy justice.

Achieving the Renewable Energy Target for Jamaica

Full Text Available ieving the Renewable Energy Target for Jamaica Abstract: The high cost of energy in Jamaica, one of the highest in the Caribbean region, is usually cited as a hindrance to industrial development and efficiency, especially in the manufacturing sector. High energy cost is also considered to be a national energy security issue and the government is taking steps to ensure adequate supply of energy at affordable prices. In the current National Development Plan, the government has set a target for renewable energy sources to supply 20% of the country's energy need by the year 2030. Using a linear programing model of energy planning, we examine how realistically this target could be achieved. Our findings indicate that the 20% renewable energy target is technically achievable with the optimal plan showing a mixture of wind power, hydropower and bagasse power but no solar power. However, when the timeline for investment in new generating capacities that will ensure the attainment of the target is considered, it becomes highly improbable that the target will be met. This study fills the gap that exists in evidence-based analysis of energy policy in Jamaica.

Nuclear energy and its synergies with renewable energies

International Nuclear Information System (INIS)

Carre, F.; Mermilliod, N.; Devezeaux De Lavergne, J.G.; Durand, S.

2011-01-01

France has the ambition to become a world leader in both nuclear industry and in renewable energies. 3 types of synergies between nuclear power and renewable energies are highlighted. First, nuclear power can be used as a low-carbon energy to produce the equipment required to renewable energy production for instance photovoltaic cells. Secondly, to benefit from the complementary features of both energies: continuous/intermittency of the production, centralized/local production. The future development of smart grids will help to do that. Thirdly, to use nuclear energy to produce massively hydrogen from water and synthetic fuels from biomass. (A.C.)

The book also contains a free CD-ROM resource, which includes a variety of specialist simulation software and detailed figures from the book. (Author)

The first step towards a 100% renewable energy-system for Ireland

International Nuclear Information System (INIS)

Connolly, D.; Leahy, M.; Lund, H.; Mathiesen, B.V.

2011-01-01

In 2007 Ireland supplied 96% of the total energy demand with fossil fuels (7% domestic and 89% imported) and 3% with renewable energy, even though there are enough renewable resources to supply all the energy required. As energy prices increase and the effects of global warming worsen, it is essential that Ireland begins to utilise its renewable resources more effectively. Therefore, this study presents the first step towards a 100% renewable energy-system for Ireland. The energy-system analysis tool used was EnergyPLAN, as it accounts for all sectors of the energy-system that need to be considered when integrating large penetrations of renewable energy: the electricity, heat, and transport sectors. Initially, a reference model of the existing Irish energy-system was constructed, and subsequently three different 100% renewable energy-systems were created with each focusing on a different resource: biomass, hydrogen, and electricity. These energy-systems were compared so that the benefits from each could be used to create an 'optimum' scenario called combination. Although the results illustrate a potential 100% renewable energy-system for Ireland, they have been obtained based on numerous assumptions. Therefore, these will need to be improved in the future before a serious roadmap can be defined for Ireland's renewable energy transition. (author)

The EU renewable energy (RES) directive sets a target of increasing the share of renewable energy used in the EU to 20% by 2020. The Norwegian goal for the share of renewable energy in 2020 is 67.5%, an increase from 60.1% in 2005. The Norwegian power production is almost solely based on renewable resources and the possibility to change from fossil power plants to renewable power production is almost non-existing. Therefore other measures have to be taken to fulfil the RES directive. Possible ways for Norway to reach its target for 2020 are analysed with a technology-rich, bottom-up energy system model (TIMES-Norway). This new model is developed with a high time resolution among others to be able to analyse intermittent power production. Model results indicate that the RES target can be achieved with a diversity of options including investments in hydropower, wind power, high-voltage power lines for export, various heat pump technologies, energy efficiency measures and increased use of biodiesel in the transportation sector. Hence, it is optimal to invest in a portfolio of technology choices in order to satisfy the RES directive, and not one single technology in one energy sector. - Highlights: • A new technology-rich, bottom-up energy system model is developed for Norway. • Possible ways for Norway to reach its renewable energy target for 2020 is analysed. • Results show that the renewable target can be achieved with a diversity of options. • The green certificate market contributes to increased investments in wind power

Renewable energy policy in South Africa: policy options for renewable electricity

2005-01-01

Investment in renewable energy and energy efficiency is important to reduce the negative economic, social and environmental impacts of energy production and consumption in South Africa. Currently, renewable energy contributes relatively little to primary energy and even less to the consumption of commercial energy. This article examines policy options for promoting renewable electricity. Feed-in tariffs guarantee prices for developers, but lack certainty on the amount of renewable electricity such laws would deliver under local conditions. Portfolio standards set a fixed quantity, which would guarantee diversity of supply. The question is whether the incremental upfront cost to be paid by society may be unacceptably high, compared to future health and environmental benefits. A renewables obligation combines the setting of a target with a tendering process, but may be bureaucratic to administer. Neither setting targets or regulating prices alone, however, will be sufficient. Power purchase agreements, access to the grid and creating markets for green electricity are some supporting activities that should be considered. Given that renewable electricity technologies have to compete with relatively low electricity tariffs, funding will be needed. Possible sources, both locally and internationally, are identified. The extent to which these are utilised will determine the future mix of renewable energy in South Africa. (author)

On market integration of renewable energies

Since the liberalization of electricity and gas markets in Europe, the energy sector has changed in every respect with one constant: most actors have underestimated renewable energies with regard to their growth, their economies of scale and their impact on existing energy markets. If that trend continues, the urgency for policy measures will increase. Given the security of supply, integration of renewables into energy markets is necessary to replace fossil and nuclear capacities. However, the further development of renewable energies plays a crucial role in the ability to meet the energy and climate policy targets. Thus, it increases the need for regulation to achieve societally desirable outcomes. This thesis has examined the effects of renewable energies on existing energy markets. It has also investigated the various other cost-efficient options that policy makers have in striving to reach energy and climate policy targets. We assumed that cost efficiency is a relevant side condition. In the past, this has not always been the case. Today, cost efficiency is definitely relevant and might also be an essential target in the future (see Bundesregierung 2013, p. 50). We contributed to the analysis of power prices as a result of increasing shares of renewables by showing that shutting down conventional capacities will have a merit order effect. This is necessary if renewable energies are to replace fossil and nuclear capacities. Any discussion of a change of market design should make mention of this effect, since spot market revenues impact a company's behaviour within potential capacity markets. From a consumer perspective, we have shown that there is a substantial need for secured capacity with low marginal costs to keep spot prices stable. This outcome has important implications for policy makers if they are to provide consumers with low-cost renewable market integration. Policy makers have numerous ways to reach policy targets than rapidly expanding

Renewable energy can become the major energy supply option in low-carbon energy economies. Disruptive transformations in all energy systems are necessary for tapping widely available renewable energy resources. Organizing the energy transition from non-sustainable to renewable energy is often described as the major challenge of the first half of the 21st century. Technological innovation, the economy (costs and prices) and policies have to be aligned to achieve full renewable energy potentials, and barriers impeding that growth need to be removed. These issues are also covered by IPCC's special report on renewable energy and climate change to be completed in 2010. This article focuses on the interrelations among the drivers. It clarifies definitions of costs and prices, and of barriers. After reviewing how the third and fourth assessment reports of IPCC cover mitigation potentials and commenting on definitions of renewable energy potentials in the literature, we propose a consistent set of potentials of renewable energy supplies.

The US Army Corps of Engineers has retained Idaho National Laboratory (INL) to conduct a study of past INL experiences and complete a report that identifies the processes that are needed for the development of renewable energy projects on government properties. The INL has always maintained expertise in power systems and applied engineering and INL’s renewable energy experiences date back to the 1980’s when our engineers began performing US Air Force wind energy feasibility studies and development projects. Over the last 20+ years of working with Department of Defense and other government agencies to study, design, and build government renewable projects, INL has experienced the do’s and don’ts for being successful with a project. These compiled guidelines for government renewable energy projects could include wind, hydro, geothermal, solar, biomass, or a variety of hybrid systems; however, for the purpose of narrowing the focus of this report, wind projects are the main topic discussed throughout this report. It is our thought that a lot of what is discussed could be applied, possibly with some modifications, to other areas of renewable energy. It is also important to note that individual projects (regardless the type) vary to some degree depending on location, size, and need but in general these concepts and directions can be carried over to the majority of government renewable energy projects. This report focuses on the initial development that needs to occur for any project to be a successful government renewable energy project.

The development of renewable energies and supply security: A trade-off analysis

International Nuclear Information System (INIS)

Röpke, Luise

2013-01-01

This paper analyzes the effects of the green transformation on the German electricity sector with respect to the energy-political triangle. It focuses on how the development of renewable energies will affect security of electricity supply. In a cost–benefit analysis, the value of supply security is compared with its costs of provision. More specifically, the benefits of maintaining the present quality of electricity supply are the avoided social damages from electricity outages and are compared with the respective investment costs in the low- and medium-voltage distribution grid. It is shown that the transformation process towards a green and decentralized production structure will be costly for society, even though the costs can be reduced by different measures. - Highlights: • The effects of the transformation on the German electricity sector are analyzed. • The paper focuses on the trade-off between green energies and supply security. • The benefits of maintaining supply quality are compared with the investment costs. • The costs of maintaining supply quality by far exceed the induced welfare gains. • A strong focus on renewable energies endangers different energy-political goals

Complementarity and substitution of renewable energy in target year energy supply-mix plannin–in the case of Taiwan

Renewable energies are eco-friendly and sustainable. However, their development faces two critical issues: the uncontrollable generation variability, and the high levelized cost. These two issues impede the development of renewables substitution for a government from lacking of clearly argument of how to promote renewables substitution, and what is the role of traditional generation resources should play to back up the renewable energies in a target year. This study aims to depict the possibility of the concerned topic from the aspects of economy, security, and environment, taking a top–down viewpoint of policy-making to address an energy supply problem, and proposes an Energy Supply-Mix Model by considering the complimentary and substitution possibilities between renewable and non-renewable energies, and also among the renewable energies. The solution provides an overall assessment of three aspects under the conditions of supply and demand balance, desired generation percentage of renewable energies, and also ensure no shortage in peak-hour demand. Parametric analysis on the carbon tax is particularly conducted for policy making reference. This study takes Taiwan as a case and performs the scenario analysis according to the recent energy policies. The results have shown that the proposed model can effectively support a decision body for policy formulation. - Highlights: • Discuss renewable and non-renewable energy substitution. • Discuss the complementary among renewable energies. • The MOLP model achieves goals of economy, environment, energy supply-mix. • Scenario and sensitivity analyses are for policy support. • Case of Taiwan supports the applicability and validity.

Transforming the New Brunswick Energy Hub: An Analysis on Renewable Energy

Science.gov (United States)

Gunter, Christopher

This research examines the benefits and disadvantages of instituting a shift from fossil fuel dependence to renewable sources of energy in New Brunswick. The New Brunswick Energy Hub is a complex system acting under the mandate of the White Paper New Brunswick Energy Policy. In my research, I consider information derived from statistical indicators developed by Patlitzianas, Doukas, Kagiannas and Psarras (2008) and compare these findings to the efficacy of energy policies in Germany, Denmark and Spain. These countries are similar to New Brunswick in climate and organizational complexity (US Department of Commerce, 2009). Weighing the outcomes of this comparative study, I discuss my recommendations highlighting the environmental and economic benefits. My research investigates subsidies in each country that allowed them early economic and environmental advantages. Specific regional considerations, such as Denmark's trend of selling energy technology for profit over domestic applications, inform my conclusions. The future New Brunswick Energy Policy should focus on creating favorable conditions for renewable energy development to occur. Some proven conditions include infrastructure development subsidies and the development and annual review of a competitive open access transmission tariff. With the expiry of the current White Paper comes the necessity of this investigation, and the opportunity to address the growing financial and environmental concerns that many politicians and policy planners have failed to deal with in past policies.

Methology. The survey is based on an analysis of the natural potential, legislative frameworks of the industry and active financial programmes. Results of the survey provide the most attractive opportunities for investing in the emerging market of renewable energy in Ukraine. The survey also shows the amount of economically viable potential of different renewable energy sources. Besides, it is expected that renewable energy will enhance energy security and reduce the negative impact of industry on the environment. Practical implications. Since 2009 when the green tariff was first introduced in Ukraine, the renewable energy sector has been developed to a great extent. Although the sector faced some policy challenges in 2015, such as the imposition of new taxes, but technologies experienced rapid growth. Nowadays the use of renewable energy sources is a priority way of sustainable energy system building in Ukraine. There are several state and regional financial initiatives promoting renewable energy sources. As policymakers have focused on the renewable energy development, new investment centered in energy efficiency technologies. There will be a big step in the direction of renewables usage in private housing complexes. Due to the survey, the main problem of renewable energy development is lack of funding. All the efforts made by the government create an enabling environment for foreign direct investments in renewable energy in Ukraine. Value/originality. Wide renewable energy use would be a

Csatári, Nándor; Vántus, András

2015-04-01

The recent measures in the European Union promote the usage of renewable energies and enhancing the energy efficiency. These measures also effect agriculture, on the one hand by using biofuels mixed into fuel for machinery. Besides biofuels animal farms have opportunities in using renewable energy in several other ways. There are sectors in animal farming, where the energy demand is continuously high in electricity (e.g. forage grinders, mixers, milk coolers, air ventilation systems) or in heating (e.g. stables for poultry or piglets). Beside the energy demand in agricultural sector there are several products and side products suitable for energy production. For example different kinds of organic manures and corn silage could be raw materials for biogas production; plant residues like cereal straw and corn stalk bales could be combusted in boilers. Furthermore solar cells or solar collectors can be mounted on the big roof surfaces of animal farm buildings. Among animal farming sectors, dairy farming in the most energy intensive, and uses the widest variety of energy forms. It is often mentioned as the "heavy industry" of animal farming. In this research 14 dairy farms were examined in Hajdú-Bihar County in the topic of energy demand, renewable energy usage. The questioned farms covers 35% of the dairy cow population in Hajdú-Bihar County. The questions covered the general attributes of the farms and the details of the (existing or planned) renewable energy application. In terms of economic analysis saving, the investment return time and the employment effect was examined. The results show wide variety of applied renewable energy application. Fifty percent of farms uses at least one kind of renewable energy. Two biogas plants, 6 boilers for solid biomass, 2 solar cells. Regarding employment effect biogas plants created some full time workplaces, biomass boilers also needs some work hours to maintain, but none of the farms applied more labour. Besides renewable

The EurObserv'ER policy profiles give a snapshot of the renewable energy policy in the EU Member States. In Hungary, electricity from renewable energy sources is supported by a feed-in-tariff or a market ('green') premium, depending on the capacity and energy source. Household-sized power plants up to 50 kVA can benefit from net metering. In general, subsidy programmes also promote the use of renewable energy sources in the electricity and heating sector. The main support scheme for the use of renewable energy in the transportation sector is a quota system supplemented by a reimbursement of excise duty

Full Text Available Taking the expected growth of the world’s population and the estimated technological development and increase in living standards into account, the paper forecasts energy demands. On the basis of the actual production data of 380-400 EJ.year-1 in 2000 and data in publications, the author assumes the total energy demand to be 750-800 EJ.year-1 for 2030, 600-1,000 EJ.year-1 for 2050 and 900-3,600 EJ.year-1 for 2100. The author analyses the appearance of the different energy types in the history of mankind giving the specific heat content and heating value of the different fuels. The environmental advantages, disadvantages, technical and economic limits of application involved in the use of primary renewable energy sources are also dealt with. The analysis of the data in the different prognoses in publications gives the result that fossil fuels will meet 84-85 % of the total energy demand until 2030 in the foreseeable future. In 2050, the fossil rate may be 50-70 % and the rate of renewables may amount to 20-40 %. In 2100, the maximum fossil rate may be 40-50 % with a 30-60 % maximum rate of renewables. On the basis of the results of investigation, the general conclusion may be that the realistically exploitable amount of renewable energy sources is not so unlimitedly high as many suppose. Therefore, it is an illusion to expect that the replacement or substitution of mineral fuels and nuclear energy can be solved relying solely on renewable energies.

Role of renewable energy for the 21st century

The present high energy paradigm of consumerism and armament is almost entirely structured on non-renewable fossil fuels. This commitment is now being further extended through massive new infrastructures and life styles to the emerging new nations. Arising out of the energy concentration and constraints of the economic parameters, movement towards low density sun-based sources of energy will be slow and halting. In the final analysis the factors, which will determine the timescale and speed of shift to renewable sources of energy, would include:- the declining economic availability and increasing conflicts in the acquisition of non renewable resources, crossing of he threshold of environmental sustainability of parameters such as doubling of Carbon dioxide, ozone layer depletion and health endangering pollution, and nuclear wastes etc., the available times scale for substitution with renewables, movement away from high energy, high technology consumerist life style and their armament support system.

The first version of REN21's Renewables Global Futures Report (GFR) published in January 2013 identified a panorama of likely future debates related to the renewable energy transition. As a reflection of the wide range of contemporary thinking by the many experts interviewed for the report, it did not present just one vision of the future but rather a 'mosaic' of insights. Given the positive feedback in response to the first edition, a new edition has been prepared, continuing where the last one left off. The objective of this report is to gather opinions about the feasibility of a 100% renewable energy future, and the macro-economic impacts it would entail. In so doing, the report reflects on the debates of 2013, and tracks their evolution to the present time. Some remain, some have changed, some have been overtaken by progress, and new ones have arisen. They are summarised here as the Great Debates in renewable energy. The questionnaire for the survey was developed in close cooperation between the REN21 Secretariat, the Institute for Sustainable Future (ISF) of the University of Technology Sydney/Australia (UTS) and the Institute for Advanced Sustainability Studies (IASS) in Potsdam/Germany. It covered the following topics: 1. How much renewables?; 2. Power sector; 3. Heating and cooling; 4. Transport; 5. Storage; 6. Demand-side management and energy efficiency; 7. Integration of sectors; 8. Macro-economic considerations; 9. Technology and costs; 10. Policy; 11. Cities; 12. Distributed renewable energy/energy access; 13. Barriers/challenges/enablers. 114 experts were interviewed in total; the average interview time was approximately one hour. The interviews were conducted between May and October 2016. The questionnaire was also mirrored in an online version and used both by interviewers and interviewees to record the interview process. Interviewees were selected from the following regions: Africa, Australia and Oceania, China, Europe, India, Japan, Latin America

Highlights: ► Feedback of decisions to the market: large companies can have an impact on prices in the market. ► Multiple uncertainties: analysis of uncertainties emanating from both markets and environment. ► Policy analysis: impact of uncertainty about the durability of feed-in tariffs. -- Abstract: The liberalization of electricity markets in recent years has enhanced competition among power-generating firms facing uncertain decisions of competitors and thus uncertain prices. At the same time, promoting renewable energy has been a key ingredient in energy policy seeking to de-carbonize the energy mix. Public incentives for companies to invest in renewable technologies range from feed-in tariffs, to investment subsidies, tax credits, portfolio requirements and certificate systems. We use a real options model in discrete time with lumpy multiple investments to analyze the decisions of an electricity producer to invest into new power generating capacity, to select the type of technology and to optimize its operation under price uncertainty and with market effects. We account for both the specific characteristics of renewables and the market effects of investment decisions. The prices are determined endogenously by the supply of electricity in the market and by exogenous electricity price uncertainty. The framework is used to analyze energy policy, as well as the reaction of producers to uncertainty in the political and regulatory framework. In this way, we are able to compare different policies to foster investment into renewables and analyze their impacts on the market.

The impacts of non-renewable and renewable energy on CO2 emissions in Turkey.

As a result of great increases in CO 2 emissions in the last few decades, many papers have examined the relationship between renewable energy and CO 2 emissions in the energy economics literature, because as a clean energy source, renewable energy can reduce CO 2 emissions and solve environmental problems stemming from increases in CO 2 emissions. When one analyses these papers, he/she will observe that they employ fixed parameter estimation methods, and time-varying effects of non-renewable and renewable energy consumption/production on greenhouse gas emissions are ignored. In order to fulfil this gap in the literature, this paper examines the effects of non-renewable and renewable energy on CO 2 emissions in Turkey over the period 1970-2013 by employing fixed parameter and time-varying parameter estimation methods. Estimation methods reveal that CO 2 emissions are positively related to non-renewable energy and renewable energy in Turkey. Since policy makers expect renewable energy to decrease CO 2 emissions, this paper argues that renewable energy is not able to satisfy the expectations of policy makers though fewer CO 2 emissions arise through production of electricity using renewable sources. In conclusion, the paper argues that policy makers should implement long-term energy policies in Turkey.

Due to the mounting demand for energy and increasing population of the world, switching from nonrenewable fossil fuels to other energy sources is not an option-it is a necessity. Focusing on a cost-effective option for the generation of electricity, Wind Energy: Renewable Energy and the Environment covers all facets of wind energy and wind turbines. The book begins by outlining the history of wind energy, before providing reasons to shift from fossil fuels to renewable energy. After examining the characteristics of wind, such as shear, power potential, and turbulence, it discusses the measur

The first renewable energy law concerning the 'Use of Renewable Energy Resources for the Generation of Electrical Energy' was adopted from European Union regulations on 18 May 2005 in Turkey. The purpose of the Law is to expand the utilization of renewable energy resources for generating electricity. Renewables are defined in the Law as generation facilities based on wind, solar, geothermal, biomass, biogas, wave, current and tidal energy resources, hydrogen energy and hydroelectric generation facilities. The aim of the study was to use strengths, weaknesses, opportunities and threats (SWOT) analysis to identify Turkish renewable energy market strategy and perspective by focusing on four different concepts: policy, market, technology and the social dimension. Different information gathering strategies have been applied such as monitoring of all statements and press releases published in the newspapers by all Turkish renewable energy parties starting from the launch of the law, articles presented in the events between 2000 and 2008 and face-to-face interviews. Our results demonstrated the importance of technology development and knowledge creation for gaining competitiveness on the global arena and the need for a systematic approach for transforming the created know-how into economic and social benefits.

The EurObserv'ER policy profiles give a snapshot of the renewable energy policy in the EU Member States. Electricity from renewable sources is mainly promoted through feed-in premiums (FiP). In addition, investment subsidies are available for biogas/biomass-based RES-E and wind power installations. Renewable heat is stimulated through investment subsidies to CHP plants generating renewable heat and electricity, as well as subsidies for private heat consumers. Renewable transport fuels are currently mainly incentivised by way of a support scheme to promote the purchase of electric cars that use power produced from renewable energy sources. Recently, a measure for supporting bio-methane in the transport sector has been adopted. Generally, a number of investment subsidy schemes are in place to promote the development, installation and use of renewable energy production installations. However, certain subsidy conditions still have to be announced and implemented. The total amount of financial support to be allocated to renewable energy and energy efficiency related projects during period 2014-2020 will be over euro 490 million. The current administratively determined FiP scheme is set to be replaced by an auction-based scheme within short
