Only the utilization of environmental parameters like ''CO2 avoided'' may contribute to market penetration. Concerning siting, it becomes clear that only those countries below 40 degree latitude, (Madrid, Nepal, Ankara) are acceptable. A desregulation of the electrical market is necessary for solar penetration, mainly in developing countries

    When Renewable Energy for Rural Economic Development (RERED) began in 2005, Utah had no commercial wind power projects in operation. Today, the state hosts two commercial wind power plants, the Spanish Fork Wind Project and the Milford Wind Corridor Project, totaling 324 megawatts (MW) of wind capacity. Another project in San Juan County is expected to break ground very soon, and two others, also in San Juan County, are in the approval process. RERED has played a direct role in advancing wind power (and other renewable energy and clean technology innovations) in Utah through its education outreach and research/publication initiatives. RERED has also witnessed and studied some of the persistent barriers facing wind power development in communities across Utah and the West, and its research expanded to examine the diffusion of other energy efficiency and clean technology innovations. RERED leaves a legacy of publications, government reports, and documentary films and educational videos (archived at www.cleantech.usu.edu) to provide important insights for entrepreneurs, policymakers, students, and citizens about the road ahead for transitioning society onto a cleaner, more sustainable future.

    This article is the summary of a presentation at the exhibition 'Habitat and Garden' at Lausanne (Switzerland) about the effects of renewable energy development on economy and employment. Several studies over this subject do exist and some companies have a considerable know-how in this field. One particularly important question is the impact of non-renewable energy taxes. An answer is available from already published studies: taxes with a yearly yield of 800 millions CHF (about 500 millions USD) would create a net number of 60,000 to 84,000 new jobs, provided that they are integrally used for renewable energy support [de

    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.

  7. The Energy Economics of Financial Structuring for Renewable Energy Projects

    Science.gov (United States)

    Rana, Vishwajeet

    2011-12-01

    This dissertation focuses on the various financial structuring options for the renewable energy sector. The projects in this sector are capital-intensive to build but have relatively low operating costs in the long run when compared to traditional energy resources. The large initial capital requirements tend to discourage investors. To encourage renewable investments the government needs to provide financial incentives. Since these projects ultimately generate returns, the government's monetary incentives go to the sponsors and tax equity investors who build and operate such projects and invest capital in them. These incentives are usually in the form of ITCs, PTCs and accelerated depreciation benefits. Also, in some parts of the world, carbon credits are another form of incentive for the sponsors and equity investors to invest in such turnkey projects. The relative importance of these various considerations, however, differs from sponsor to sponsor, investor to investor and from project to project. This study focuses mainly on the US market, the federal tax benefits and incentives provided by the government. This study focuses on the energy economics that are used for project decision-making and parties involved in the transaction as: Project Developer/Sponsor, Tax equity investor, Debt investor, Energy buyer and Tax regulator. The study fulfils the knowledge gap in the decision making process that takes advantage of tax monetization in traditional after-tax analysis for renewable energy projects if the sponsors do not have the tax capacity to realize the total benefits of the project. A case-study for a wind farm, using newly emerging financial structures, validates the hypothesis that these renewable energy sources can meet energy industry economic criteria. The case study also helps to validate the following hypotheses: a) The greater a sponsor's tax appetite, the tower the sponsor's equity dilution. b) The use of leverage increases the cost of equity financing

    A first article analysis the reasons for the development of renewable energies (economic and environmental reasons, European commitments in terms of production objectives), how these renewable energies can be developed (acceptation by the population, administrative, technological, and financial constraints, political instruments related to market, taxes and purchase prices). A second article proposes a discussion about the way international law deals with renewable energies as far as texts as well as actors are concerned. The third article describes the European ambitions regarding renewable energies as a product of national perspectives (national action plans and projects) as well as of European perspectives (financing, integrated actions). The last article presents and comments various legal texts dealing with the development of renewable energies in France (texts concerning the right to energy, the environment law, planning tools, incentive measures)

  11. On the economic attractiveness of renewable energy technologies

    International Nuclear Information System (INIS)

    Jaegemann, Cosima

    2014-01-01

    The competitiveness of wind and solar power technologies is often evaluated in public debates by comparing levelized costs of electricity. This is, however, incorrect, as doing so neglects the economic value of technologies. Similarly, renewable energy support schemes are often designed to incentivize investors to only account for the marginal economic costs (MEC) but not for the marginal economic value (MEV el ) of renewable energy technologies, i.e., the revenue from selling electricity on the wholesale market during the unit's technical lifetime. In this paper, it is shown that the net marginal economic costs per kWh (NMEC) - defined as the difference between the MEC and the MEV el per kWh - should serve as the reference when discussing the economic attractiveness of renewable energy technologies. Moreover, renewable energy support schemes should incentivize investments in technologies and regions with the lowest net marginal economic costs per kWh (NMEC), as otherwise excess costs occur. This is demonstrated using the example of Germany and its technology- and region-specific wind and solar power targets for 2020. By applying a linear electricity system optimization model, Germany's technology- and region-specific wind and solar power targets for 2020 are found to cause excess costs of more than 6.6 bn Euro 2010 . These are driven by comparatively high NMEC (low economic attractiveness) of offshore wind and solar power in comparison to onshore wind power in Germany up to 2020.

    2018-05-01

    Nowadays, the use of energy is growing especially in transportation and electricity industries. However this energy is based on conventional sources which pollute the environment. Multi-source system is seen as the best solution to sustainable development. This paper proposes the Economic Dispatch (ED) of hybrid renewable power system. The hybrid system is composed of ten thermal generators, photovoltaic (PV) generator and wind turbine generator. To show the importance of renewable energy sources (RES) in the energy mix we have ran the simulation for system integrated PV only and PV plus wind. The result shows that the system with renewable energy sources (RES) is more compromising than the system without RES in terms of fuel cost.

    Full Text Available The aim of this study is to investigate the economics of renewable energy- powered desalination, as applied to water supply for remote coastal and desert communities in developing countries. In this paper, the issue of integration of desalination technologies and renewable energy from specified sources is addressed. The features of Photovoltaic (PV system combined with reverse osmosis desalination technology, which represents the most commonly applied integration between renewable energy and desalination technology, are analyzed. Further, a case study for conceptual seawater reverse osmosis (SW-RO desalination plant with 1000 m3 /d capacity is presented, based on PV and conventional generators powered with fossil fuel to be installed in a remote coastal area in Egypt, as a typical developing country. The estimated water cost for desalination with PV/ SW-RO system is about $1.25 m3 , while ranging between $1.22-1.59 for SW-RO powered with conventional generator powered with fossil fuel. Analysis of the economical, technical and environmental factors depicts the merits of using large scale integrated PV/RO system as an economically feasible water supply relying upon a renewable energy source.

  18. Essays on the economics of decarbonization and renewable energy support

    International Nuclear Information System (INIS)

    Jaegemann, Cosima Claudia

    2014-01-01

    The thesis consists of five essays investigating various aspects associated with the decarbonization of Europe's power sector and the politically incentivized expansion of renewable energy generation. The first essay analyzes the economic implications of alternative decarbonization pathways and policy instruments for Europe's power sector up to 2050 and illustrates the importance of ensuring competition between all low-carbon technologies in order to limit the costs of decarbonization. The second essay analyzes the economic inefficiency associated with the concept of grid parity for the case of photovoltaic (PV). In order to both enhance overall welfare and avoid redistributional effects, the indirect financial incentive for in-house PV electricity consumption should be abolished. The third essay discusses the system price effect of wind and solar power generation and illustrates that the decrease in the marginal value of wind and solar power (as a consequence of increased penetration) is already highly relevant for both wind and solar power generation in Germany. The fourth essay adds to the ongoing debate surrounding the cost-efficient achievement of politically implemented renewable energy targets. Renewable energy support schemes that fail to incentivize investors to account for differences in the marginal value of wind and solar power generation are associated with excess costs as they prevent the equalization of net marginal costs across technologies and regions. The fifth essay analyzes the economic value of storage as a function of the overall generation mix and illustrates the economic inefficiency arising from feed-in tariff systems for the special case of thermal energy storage units in concentrating solar power plants.

  1. Essays in energy economics: An inquiry into Renewable Portfolio Standards

    Science.gov (United States)

    Lamontagne, Laura Marie

    In an attempt to motivate the transition away from fossil fuels, reduce carbon emissions and diversify electricity supply, twenty-nine states and the District of Columbia have adopted a Renewable Portfolio Standard (RPS). An RPS is a form of regulation that requires increased electricity production from renewable energy sources. These standards vary by state but generally require a minimum percentage of electricity generation to come from renewable technologies by a predetermined date. In the first chapter I examine the effect of the adoption of an RPS on electricity rates, making use of the increased availability of data since several policies' adoption. Using a fifty state panel over the years 1990-2010, this study uses a difference-in-difference and a fixed effects estimation to measure how the adoption of an RPS affects the price of electricity in state markets. Empirical findings show that states that have adopted an RPS have approximately a 20% higher all-retail electricity price than states that do not have RPS. Following the adoption of this regulation, a state can expect to see electricity prices rise by roughly 5% on average per year relative to states with no RPS. Once the legislation has been in place for almost a decade, electricity rates begin to dramatically increase upwards of 10% per year. In the second chapter, I observe the economic, social and political factors that prompt a state to adopt a Renewable Portfolio Standard. I estimate a probit model to determine the probability a state will adopt an RPS in a year given its present political and economic climate. Results show that a deregulated electricity market, a high per-capita GDP, a strong democratic presence in the state legislature, high renewable capacity, and a strong incidence of natural gas are indicators a state will pass an RPS. Whether or not a state is a net importer or exporter of electricity is not a significant indicator of adoption of an RPS within a state. The third chapter

    2013-01-01

    Full Text Available Current energy policy of Turkey is to increase the renewable energy share in total energy and to maximize benefit from existing potential until next 15 years. It was planed that the share of renewable energy resources in electricity production would be at least 30% by 2023 and government ensured some incentives such as feed-in tariff, investment incentives etc. for renewable energy. Moreover Turkish Energy Regulatory Agency (EMRA announced that biofuel blending would be mandatory starting from 2013 and 2014 for bioethanol (2% and biodiesel (1%, respectively. This study examines the current situation and potential of renewable resources and evaluates the impacts of renewable energy policy both on the energy sector and whole national economy. Renewable energy targets can generate around 275-545 thousand direct jobs possibilities in energy sector and 7.9 thousand tones natural gas and 464 thousand cubic meters fossil fuel saving by 2023. Net trade impact of renewable energy targets will be aggravated due to mandatory biodiesel blending since Turkey has oilseed deficit. In Turkey, utilization of all type of resources will contribute to economy but most feasible and sustainable renewable energy is biomass. Between the other renewables, biomass would provide highest social well-being in the country.

    Mannsbart, W.; Reichert, J.

    1992-01-01

    While there is a high theoretical potential for renewable energy sources in Germany, assessing theoretical potentials is more or less like playing with numbers; severe technical shortcomings and economic factors prevent then from being fully achieved. Unsuitable azimuth and slope of roofs, shading, absence of central hot water systems limit the application of collectors. The present storage technology is not suitable for a solar share higher than 50%. Individual space heating is not feasible under local climatic conditions. The broad application of biomass fuels fails because of limited resources. Feeding high amounts of fluctuating electricity generated by wind and photovoltaic systems into utility grids causes stability and storage problems. Insufficient training of installation personnel, lack of incentives for multi-family housing owners and high investment costs hinder the market penetration of renewable energy sources. Drastic cost reductions can only be expected from mass production. Therefore, appropriate policy measures - raised energy prices, as well as, subsidies or tax reliefs are necessary for market breakthrough

  7. The outlook for renewable energy in Navarre: An economic profile

    International Nuclear Information System (INIS)

    2006-01-01

    This paper describes the outlook and development of renewable energy in Navarre (Spain), which has become one of the leading regions in renewables over the last 10 years. This paper focuses its attention on the key features of the energy policy in Navarre, where there has emerged a dynamic enterprise sector. This sector has enormously increased its employment rates in the region. The success of renewable energy in Navarre is the result of the joint impact of decisive institutional support, industrial initiatives and consensus among social agents with regard to renewables. Tax incentives and local investment programs designed to break down the reluctance of local authorities and a campaign to obtain public support have, moreover, proven more efficient than the prior feed-in tariffs scheme, designed to develop the renewable energy sector and create international companies within it. The paper culminates in a detailed prognosis based on the SRN2003 survey of employment and installed power, which covers the majority of the firms operating in the Navarre renewables sector. Findings, however, suggest that the future of the sector in Navarre could be held back by the shortage of trained workers. This article might serve as a pertinent example for the deployment of renewables at regional level worldwide

    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.

    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

    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.

    This paper examines the causal relationship between CO 2 emissions, nuclear energy consumption, renewable energy consumption, and economic growth for a group of 19 developed and developing countries for the period 1984-2007 using a panel error correction model. The long-run estimates indicate that there is a statistically significant negative association between nuclear energy consumption and emissions, but a statistically significant positive relationship between emissions and renewable energy consumption. The results from the panel Granger causality tests suggest that in the short-run nuclear energy consumption plays an important role in reducing CO 2 emissions whereas renewable energy consumption does not contribute to reductions in emissions. This may be due to the lack of adequate storage technology to overcome intermittent supply problems as a result electricity producers have to rely on emission generating energy sources to meet peak load demand.

    The countries of the Middle East and North Africa (MENA) are one of the world's largest potential growth markets for renewable energy generation. Countries throughout the region have recognized the great potential of their excellent wind and solar conditions, and ample empty space, and have ambitious plans to develop solar and wind energy. They are already making progress in realizing these renewables targets. They also increasingly recognize the great potential of renewable energy in tackling a range of challenges. At a time of high unemployment, particularly among youth, the growth of renewable energy provides an engine for creating new jobs and fostering new skill profiles among workers. Renewables can increase GDP and form the basis for a significant new source of trade revenues. As a source of energy, renewables reduce dependency on fossil fuels - whether as imports, to supply energy, or as exports. This report, Economic Impacts of Desert Power (EIDP), investigates how, and under what conditions, renewables in MENA can lead to socioeconomic benefits. EIDP shows, under various scenarios, how many jobs can be expected in three exemplary MENA countries, and how the expansion of renewables can lead to higher GDP growth rates across the region. EIDP pinpoints their economic impact across sectors and countries. At the same time, EIDP describes how these effects can be maximized through immediate and sustained policy support. The report also details how such support can be tailored to foster a self-sustaining market. In short, EIDP aims to contribute to a range of debates focused on how to maximize the benefits of green growth. EIDP illustrates the following points: - MENA can benefit economically from decarbonizing - even if the rest of the world does not pursue climate action. - Exporting excess electricity is an economic opportunity for MENA countries - several North African countries could create a major export industry with renewable electricity, which

    Renewable Energy Technologies (RETs) are often recognized as less competitive than traditional electric energy conversion systems. Obstacles with renewable electric energy conversion systems are often referred to the intermittency of the energy sources and the relatively high maintenance cost. However, due to an intensified discourse on climate change and its effects, it has from a societal point of view, become more desirable to adopt and install CO 2 neutral power plants. Even if this has increased the competitiveness of RETs in a political sense, the new goals for RET installations must also be met with economical viability. We propose that the direction of technical development, as well as the chosen technology in new installations, should not primarily be determined by policies, but by the basic physical properties of the energy source and the associated potential for inexpensive energy production. This potential is the basic entity that drives the payback of the investment of a specific RET power plant. With regard to this, we argue that the total electric energy conversion system must be considered if effective power production is to be achieved, with focus on the possible number of full loading hours and the Degree of Utilization. This will increase the cost efficiency and economical competitiveness of RET investments, and could enhance faster diffusion of new innovations and installations without over-optimistic subsidies. This paper elaborates on the overall problem of the economy of renewable electric energy conversion systems by studying the interface between physics, engineering and economy reported for RET power plants in different scientific publications. The core objective is to show the practical use of the Degree of Utilization and how the concept is crucial for the design and economical optimization disregarding subsidies. The results clearly indicate that the future political regulative frameworks should consider the choice of renewable energy

    The labor market implications of large investment into renewable energy (RE) are analyzed in this text. Although a growing RE industry can be observed in Germany the overall effect of large increases of RE based electricity and heat generating technologies on the German economy require a careful model based analysis. The applied model PANTA RHEI has been used among others to evaluate the German energy concept in 2010. It takes positive and negative impacts of RE into account. The paper shows the overall effects under different assumptions for fossil fuel prices, domestic installations and international trade. The results are sensitive to assumptions on the development of RE world markets and German exports to these markets. Almost all of these scenarios exhibit positive net employment effects. Under medium assumptions net employment of RE expansion will reach around 150 thousand in 2030. Only with assumptions for German RE exports below today's level, net impacts are slightly negative. Gross employment will increase from 340 thousand in 2009 to between 500 and 600 thousand in 2030. - Highlights: ► This paper analyzes labor market implications of large investment into renewable energy (RE) in Germany. ► It shows the overall effects under different assumptions. ► The development of world markets and German RE exports are very important. ► Net employment of RE expansion will reach around 150 thousand in 2030. ► Gross employment will increase to between 500 and 600 thousand in 2030.

    This study examines the relationship between renewable energy consumption and economic growth for a panel of twenty OECD countries over the period 1985-2005 within a multivariate framework. Given the relatively short span of the time series data, a panel cointegration and error correction model is employed to infer the causal relationship. The heterogeneous panel cointegration test reveals a long-run equilibrium relationship between real GDP, renewable energy consumption, real gross fixed capital formation, and the labor force with the respective coefficients positive and statistically significant. The Granger-causality results indicate bidirectional causality between renewable energy consumption and economic growth in both the short- and long-run.

    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.

    This study was conducted with the support of the U.S. Department of Energy’s (DOE’s) Wind and Water Power Technologies Office (WWPTO) as part of ongoing efforts to minimize key risks and reduce the cost and time associated with permitting and deploying ocean renewable energy. The focus of the study was to discuss a possible approach to exploring scenarios for ocean renewable energy development in Hawaii that attempts to optimize future development based on technical, economic, and policy criteria. The goal of the study was not to identify potentially suitable or feasible locations for development, but to discuss how such an approach may be developed for a given offshore area. Hawaii was selected for this case study due to the complex nature of the energy climate there and DOE’s ongoing involvement to support marine spatial planning for the West Coast. Primary objectives of the study included 1) discussing the political and economic context for ocean renewable energy development in Hawaii, especially with respect to how inter-island transmission may affect the future of renewable energy development in Hawaii; 2) applying a Geographic Information System (GIS) approach that has been used to assess the technical suitability of offshore renewable energy technologies in Washington, Oregon, and California, to Hawaii’s offshore environment; and 3) formulate a mathematical model for exploring scenarios for ocean renewable energy development in Hawaii that seeks to optimize technical and economic suitability within the context of Hawaii’s existing energy policy and planning.

    This second edition of the Biomass Energy Success Stories covers a wide range of examples of organizations which have experienced economic benefits by substituting renewable biomass energy for non-renewable fossil fuels. In addition to the broader spectrum of industry seen to be pursuing this approach, the cases illustrate a move towards innovative and technologically more sophisticated approaches. For example, the Quebec Community's thermal accumulator acts as a buffer to accommodate the variable fuel value of boiler fuel consisting of unpredictable residues of variable moisture content. By this innovative approach, the quality of steam to its year-round customer can be held within the contractual limits. Another unique development appears in the use of the LAMB-CARGATE wet cell burner which is able to cope with wood residue fuels containing up to 70% moisture. Two of the more interesting and promising developments in the race to substitute renewable energy for fossil fuels are Fluidized Bed and Fuel-alcohol on-farm distilleries. For this reason appendices are included giving some useful insights concerning them.

    Concentrating solar power (CSP) plants are able to provide both renewable energy and operational flexibility at the same time due to its thermal energy storage (TES). It is ideal generation to power systems lacking in flexibility to accommodate variable renewable energy (VRE) generation such as wind power and photovoltaics. However, its investment cost currently is too high to justify its benefit in terms of providing renewable energy only. In this paper we evaluate the economic benefit of CSP in high renewable energy penetrated power systems from two aspects: generating renewable energy and providing operational flexibility to help accommodating VRE. In order to keep the same renewable energy penetration level during evaluation, we compare the economic costs between the system with a high share of VRE and another in which some part of the VRE generation is replaced by CSP generation. The generation cost of a power system is analyzed through chronological operation simulation over a whole year. The benefit of CSP is quantified into two parts: (1) energy benefit - the saving investment of substituted VRE generation and (2) flexibility benefit - the reduction in operating cost due to substituting VRE with CSP. The break-even investment cost of CSP is further discussed. The methodology is tested on a modified IEEE RTS-79 system. The economic justifications of CSP are demonstrated in two practical provincial power systems with high penetration of renewable energy in northwestern China, Qinghai and Gansu, where the former province has massive inflexible thermal power plants but later one has high share of flexible hydro power. The results suggest that the CSP is more beneficial in Gansu system than in Qinghai. The levelized benefit of CSP, including both energy benefit and flexibility benefit, is about 0.177-0.191 $/kWh in Qinghai and about 0.238-0.300 $/kWh in Gansu, when replacing 5-20% VRE generation with CSP generation.

    This report describes a geospatial analysis method to estimate the economic potential of several renewable resources available for electricity generation in the United States. Economic potential, one measure of renewable generation potential, may be defined in several ways. For example, one definition might be expected revenues (based on local market prices) minus generation costs, considered over the expected lifetime of the generation asset. Another definition might be generation costs relative to a benchmark (e.g., a natural gas combined cycle plant) using assumptions of fuel prices, capital cost, and plant efficiency. Economic potential in this report is defined as the subset of the available resource technical potential where the cost required to generate the electricity (which determines the minimum revenue requirements for development of the resource) is below the revenue available in terms of displaced energy and displaced capacity. The assessment is conducted at a high geospatial resolution (more than 150,000 technology-specific sites in the continental United States) to capture the significant variation in local resource, costs, and revenue potential. This metric can be a useful screening factor for understanding the economic viability of renewable generation technologies at a specific location. In contrast to many common estimates of renewable energy potential, economic potential does not consider market dynamics, customer demand, or most policy drivers that may incent renewable energy generation.

    Addressing issues of renewable energy in North Africa must incorporate concerns regarding the compatibility of energy mixes with the nature of political regimes, their geopolitical relevance, and their socio-economic effects, in addition to economic cost-benefit deliberations. One important and under-researched aspect of nuclear energy refers to the trade-off between socio-economic development and political power conservation. Competing interests in North Africa's energy market as well as aspects of regional cooperation capacity are important when assessing the choice between renewable and nuclear energy. Therefore, the future course of meeting North Africa's energy needs is subject to a complex political and economic interplay between domestic and geopolitical development interests. The objective of this paper is to explore this complexity in more detail. We argue that the identification of any energy alternative as superior is hardly convincing unless certain standards of inclusive governance are met. We also find that it is important to highlight political-economic differences between energy importers like Morocco and Tunisia and energy exporters like Algeria, Libya, and Egypt. - Research highlights: → North Africa confronted with severe energy supply challenges in near future. → Trade-off between socio-economic development and political power conservation matters. → Economic and geopolitical dimensions of trade-off heterogeneous across North Africa.

    Short, W.; Packey, D.J.; Holt, T.

    1995-03-01

    This manual is a guide for analyzing the economics of energy efficiency and renewable energy (EE) technologies and projects. It is intended (1) to help analysts determine the appropriate approach or type of analysis and the appropriate level of detail and (2) to assist EE analysts in completing consistent analyses using standard assumptions and bases, when appropriate. Included are analytical techniques that are commonly required for the economic analysis of EE technologies and projects. The manual consists of six sections: Introduction, Fundamentals, Selection Criteria Guide, Economic Measures, Special Considerations for Conservation and Renewable Energy Systems, and References. A glossary and eight appendices are also included. Each section has a brief introductory statement, a presentation of necessary formulae, a discussion, and when appropriate, examples and descriptions of data and data availability. The objective of an economic analysis is to provide the information needed to make a judgment or a decision. The most complete analysis of an investment in a technology or a project requires the analysis of each year of the life of the investment, taking into account relevant direct costs, indirect and overhead costs, taxes, and returns on investment, plus any externalities, such as environmental impacts, that are relevant to the decision to be made. However, it is important to consider the purpose and scope of a particular analysis at the outset because this will prescribe the course to follow. The perspective of the analysis is important, often dictating the approach to be used. Also, the ultimate use of the results of an analysis will influence the level of detail undertaken. The decision-making criteria of the potential investor must also be considered.

    This comprehensive lecture given by Prof. Dr. Gunter Schaumann in Bad Duerkheim, Germany, discusses the use of geothermal energy in relationship to other forms of renewable energy sources and conventional energy technologies used to provide heat, power and motive force. The characteristics of geothermal energy from various sources and examples of its possible use are discussed. In particular, the paper deals with deep geothermal energy, which can provide heating energy for district heating schemes, if necessary with the help of heat pumps. The prospects of such a use of geothermal energy in the next 50 years in various suitable regions in Germany is discussed and the associated prerequisites are listed. The present situation concerning the use of geothermal energy in Germany is examined. An example of a geothermal heating power station that also features a gas-fired combined heat and power installation, a heat pump and a peak-load boiler is given. Also, the generation of electrical power using the Organic Rankine Cycle is discussed. The factors influencing the economic viability of geothermal power stations are discussed in detail and the resulting energy prices are compared with conventional plants. The paper gives details of the calculation of investment and energy costs for heat and power generation and presents figures based on exemplary installations

    Projected cost-performance data are used to calculate the Canadian commercial potential of selected renewable energy technologies to the year 2010. Based on projected market penetration, the extent to which renewable energy can contribute to environmental initiatives is also examined. The potential for renewable energy to contribute to the Canadian electricity supply is limited neither by the state of the technology nor the extent of the resource available. Barriers to acceptance of renewables include high initial capital costs, intermittent nature of much of the energy supply, land requirements, onerous requirements for environmental assessments and licensing, and lack of government policies which consider the externalities involved in new energy supply. Environmental benefits which will drive the adoption of renewables in Canada include the sustainable nature of renewable resources, low environmental impacts, and suitability for integrated resource planning. In addition, the cost performance of renewable technologies is improving rapidly. Under base-case scenarios, at current buyback rates, only small hydro and biomass of the five renewable technologies examined has significant commercial potential in Canada. At buyback rates that reflect currently projected avoided costs plus an additional 2 cents per kWh as an environmental premium, all five renewable technologies except for photovoltaics have appreciable commercial potential achievable by 2010. The quantity of electrical energy displaced under this latter scenario is estimated at 49 TWh/y, or 7% of the projected total generation in Canada. 2 figs., 2 tabs

    Full Text Available In this paper, we focus on the sustainability and economic performance of the renewable energy sector of Romania. In our analysis, we have used Total Quality Management (TQM model, which is an economic modern tool used for improving the quality of management for all companies. The aim of this study is to bring into discussion the conceptualized TQM model of Edward Deming underlying different stages of its evolution as it is described in the economic literature. Conceptual model is applied in a case study of the renewable energy sector of Romania. The quantitative research evaluates the impact of the total quality management to achieve the sustainable development, performance objectives and the competitive advantage of the companies in the renewable energy sector. Data was collected through a survey and the questionnaire was addressed to the management and employees in the renewable energy sector. Structural equation modelling (SEM was used and the hypotheses were tested by partial least square (PLS equations. Data was analyzed through the Smart PLS 3 software. The main contribution of this paper is to identify and evaluate the relationship among sustainable development, economic performance of the companies and TQM model indicators. The conclusions of our research are in line with the existing literature and confirm the theoretical assumptions, underlining the fact that the undertaking’s performance and sustainable development is a direct consequence of the combination among a series of factors like decisional power quality, motivated workforce as well as integrity of operational process.

    This study explores the causal relationship between carbon dioxide (CO 2 ) emissions, renewable and nuclear energy consumption and real GDP for the US for the period 1960-2007. Using a modified version of the Granger causality test, we found a unidirectional causality running from nuclear energy consumption to CO 2 emissions without feedback but no causality running from renewable energy to CO 2 emissions. The econometric evidence seems to suggest that nuclear energy consumption can help to mitigate CO 2 emissions, but so far, renewable energy consumption has not reached a level where it can make a significant contribution to emissions reduction.

    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....

    The main objective of this study was to analyze the impact of energy consumption (divided into renewable and non-renewable sources) and income on CO 2 emissions within the environmental Kuznets curve (EKC) model for the Southern Common Market (MERCOSUR). To do so, the annual panel data collected during the 1990-2014 periods was used. The CO 2 variable, representing carbon dioxide emissions in metric tons per capita, was used as a proxy for the emission of pollutants. The annual data were obtained from the World Bank (World Development Indicators). The sample consisted of the five MERCOSUR member countries: Argentina, Brazil, Paraguay, Uruguay, and Venezuela, comprising a period of 25 consecutive years. The results showed that energy consumption from renewable sources had a negative impact on CO 2 emissions, while the energy consumption from non-renewable sources had a positive impact. The positive impact of economic development on CO 2 emissions was also seen. In addition, this study supports the validity of the EKC hypothesis for the MERCOSUR because GDP (real output) leads to environmental degradation while GDP 2 reduces the level of gas emissions.

    This paper describes a project whose goals include the establishment of a pilot renewable energy-based rural energy services enterprise to serve communities in the Mamprusi East District, focused on: economically productive activities; community services; household non-thermal energy. The program also seeks to establish the technical, economic, financial, institutional, and socio-cultural requirements for sustainability, to demonstrate bankability and financial sustainability, as a pre-investment prelude to commercial growth of such projects, and to establish technical, financial, and service performance standards for private sector rural energy service companies. This project is being implemented now because the government is undergoing structural reform, including privatization of the power sector, there is active foreign capital available for international development, and the government and people are committed to and able to pay for renewable energy services.

    With increasing global energy demand and declining energy return on energy invested (EROEI) of crude oil, global energy consumption by the O&G industry has increased drastically over the past few years. In addition, this energy increase has led to an increase GHG emissions, resulting in adverse environmental effects. On the other hand, electricity generation through renewable resources have become relatively cost competitive to fossil based energy sources in a much ‘cleaner’ way. In this study, renewable energy is integrated optimally into a refinery considering costs and CO2 emissions. Using Aspen HYSYS, a refinery in the Middle East was simulated to estimate the energy demand by different processing units. An LP problem was formulated based on existing solar energy systems and wind potential in the region. The multi-objective function, minimizing cost as well as CO2 emissions, was solved using GAMS to determine optimal energy distribution from each energy source to units within the refinery. Additionally, an economic feasibility study was carried out to determine the viability of renewable energy technology project implementation to overcome energy requirement of the refinery. Electricity generation through all renewable energy sources considered (i.e. solar PV, solar CSP and wind) were found feasible based on their low levelized cost of electricity (LCOE). The payback period for a Solar CSP project, with an annual capacity of about 411 GWh and a lifetime of 30 years, was found to be 10 years. In contrast, the payback period for Solar PV and Wind were calculated to be 7 and 6 years, respectively. This opens up possibilities for integrating renewables into the refining sector as well as optimizing multiple energy carrier systems within the crude oil industry

  11. Economic evaluation of innovative storage technologies in energy systems with a high share of renewable energies

    2017-01-01

    This work addresses the question of whether the ongoing transformation to a low-carbon energy system in Germany will also create market opportunities for innovative market participants, in particular for storage operators. The economic effects that occur in energy systems with high levels of variable renewable energy (vEE) can be measured by their integration costs. Scientific research into the additional storage and flexibility needs of such an energy system often addresses imbalances in the system balance sheet. The respective methods are, however, based on different assumptions and framework conditions, so that the results can only be compared with one another to a limited extent. The hourly fluctuating wholesale price on the electricity exchange is an important indicator to signal the need for flexibility. Many analyzes use historical or predicted pricing time series to evaluate storage options. However, while the feedback of the operation of an energy storage on the market prices is left out. Therefore, a method is developed in this work to estimate the impact of an increasing market volume of storage and other flexibility options on spot market prices. The influence of storage use on electricity demand and spot market prices in 2020 and 2030 is examined. The scenarios to be defined for the electricity market are model-based and evaluated. To answer the question, techno-economic models, e.g. The MICOES power market model for power plant deployment planning, the DeSiflex model for smoothing residual load through integrated flexibility options and the Arturflex model for estimating arbitrage gains through the use of flexibility options on the spot market.

    Khatib, Hisham; Difiglio, Carmine

    2016-01-01

    This paper provides an assessment of the economic challenges faced by both nuclear power and “new” renewable electricity technologies. The assessment reflects the need to incorporate new renewables into power grids and issues faced in dispatching power and their effect on traditional electricity technologies as well as the need for transmission extension and/or grid reinforcement. Wider introduction of smart grids and the likely demise of nuclear in some OECD countries are bound to enhance the future prospects for new renewables. However, their immediate future expansion will depend on continued subsidies, which are becoming difficult to sustain in present economic circumstances. Development of large energy storage facilities and carbon pricing could significantly enhance future renewable energy prospects. Correspondingly, expanding renewable energy, in spite of their popularity with some governments and sections of the public, is likely to face challenges which will slow their present rapid progress. Nuclear is now shied away from in many industrialized countries and having mixed prospects in developing economies. In many instances, it suffers from high initial costs, long lead times and often excessive construction delays. Nuclear power also faces challenging risks – investment as well as regulatory. In contrast to renewables, its share of global energy consumption is declining. - Highlights: •Renewables are increasing their energy share. •Renewables system cost is higher than their production cost. •Nuclear share is not increasing and their costs are not reduced. •Discount rate and subsidies are important in economics of renewables and nuclear.

  13. Economics of Renewable Energy Integration and Energy Storage via Low Load Diesel Application

    Directory of Open Access Journals (Sweden)

    James Hamilton

    2018-04-01

    Full Text Available One-quarter of the world’s population lives without access to electricity. Unfortunately, the generation technology most commonly employed to advance rural electrification, diesel generation, carries considerable commercial and ecological risks. One approach used to address both the cost and pollution of diesel generation is renewable energy (RE integration. However, to successfully integrate RE, both the stochastic nature of the RE resource and the operating characteristics of diesel generation require careful consideration. Typically, diesel generation is configured to run heavily loaded, achieving peak efficiencies within 70–80% of rated capacity. Diesel generation is also commonly sized to peak demand. These characteristics serve to constrain the possible RE penetration. While energy storage can relieve the constraint, this adds cost and complexity to the system. This paper identifies an alternative approach, redefining the low load capability of diesel generation. Low load diesel (LLD allows a diesel engine to operate across its full capacity in support of improved RE utilization. LLD uses existing diesel assets, resulting in a reduced-cost, low-complexity substitute. This paper presents an economic analysis of LLD, with results compared to conventional energy storage applications. The results identify a novel pathway for consumers to transition from low to medium levels of RE penetration, without additional cost or system complexity.

    This final technical report of the study contains the important equations and results of the above mentioned project. The main aim of the study was to show the importance of renewable energy in Nordrhein-Westfalen regarding its possible contribution to the energy supply as well as the reduction of carbon dioxide emissions, caused by the convertion of energy. Considering the energy sources photovoltaic, solar heating, wind and biomass, an economically oriented energy mix of renewable energy systems is developed, which describes the most economical combination of renewable energy sources and its production costs in dependence on the converted energy. In this connection a regional disaggregated estimation of the theoretical possible maximum contribution of the single renewable energy sources to the energy supply in the communities of Nordrhein-Westfalen is investigated. Basing on this estimation and on the technical datas of commerical manufactured systems, converting the energy sources sun, wind and biomass, the technical possibilities for an extension of the renewable energy are determined for every community. The result of the examinations shows, that the energy supply in Nordrhein-Westfalen could by based in future on barely a fourth by using renewable energy sources, on barely a third by using energy more efficient and on nearly the half by using fossil and nuclear energy sources. The costs however, which would be connected with an extension of renewable energy sources according to the suggested energy mix, can economical not be accepted in the further future. (orig./UA) [de

  16. A technical and economic analysis of one potential pathway to a 100% renewable energy system

    Directory of Open Access Journals (Sweden)

    2014-02-01

    Full Text Available This paper outlines how an existing energy system can be transformed into a 100% renewable energy system. The transition is divided into a number of key stages which reflect key radical technological changes on the supply side of the energy system. Ireland is used as a case study,but in reality this reflects many typical energy systems today which use power plants for electricity, individual boilers for heat, and oil for transport. The seven stages analysed are 1 reference, 2 introduction of district heating, 3 installation of small and large-scale heat pumps,4 reducing grid regulation requirements, 5 adding flexible electricity demands and electric vehicles, 6 producing synthetic methanol/DME for transport, and finally 7 using synthetic gas to replace the remaining fossil fuels. For each stage, the technical and economic performance of the energy system is calculated. The results indicate that a 100% renewable energy system can provide the same end-user energy demands as today’s energy system and at the same price. Electricity will be the backbone of the energy system, but the flexibility in today’s electricity sector will be transferred from the supply side of the demand side in the future. Similarly, due to changes in the type of spending required in a 100% renewable energy system, this scenario will result in the creation of 100,000 additional jobs in Ireland compared to an energy system like today’s. These results are significant since they indicate that the transition to a 100% renewable energy system can begin today, without increasing the cost of energy in the short- or long-term, if the costs currently forecasted for 2050 become a reality.

    Securing energy demand for next generations is one of the most challenges aspects facing any sustained development plans, due to the growing electric energy demand and Egypt as a country of limited fossil fuel resources has to diversify its energy portfolio by utilization of its renewable energy resources, mainly wind due to its economic potential and solar as proved by Egypt's wind and solar atlases. In the year 2009/2010, the total installed capacity in Egypt was 24726 MW with electricity generation 139,000 GWh, of which 89 % was delivered by thermal plants and about 10% from Hydro power with total installed 2800 MW and electricity generated is about 12863 GWh and 1% from Wind energy with total installed 550 MW and electricity generated 1542 GWh. In the solar energy field, the first solar thermal power plant of 140 MW with a solar share of 20 MW using parabolic trough technology was started the initial work since the 1 st of July with estimated total energy generated of 852GWh/year. Recently, Egypt has adopted an ambitious plan to cover 20% of the generated electricity by renewable energy by 2020, including a 12% contribution from wind energy, translating more than 7200 MW grid-connected wind farms. Such plan gives a room enough to the private investment to play the major role in realizing this goal. The plan includes also a 100 MW Solar thermal energy CSP with parabolic trough technology in Kom Ombo city, and also two PV plants in Hurgada and Kom Ombo with a total installed capacity 20 MW each. Due to the high investment cost of solar energy technologies, still limited in spread all over the world on the other hand wind energy has an economic potential and becomes a commercial technology but the future potential for solar energy due to the limited land for wind energy. Current study will evaluate the Egyptian strategy for renewable energy up to 2020 and find how much the planned projects from the Egyptian government will fulfill its target, the economic study

    Globally, small islands below 100,000 inhabitants represent a large number of diesel based mini-grids. With volatile fossil fuel costs which are most likely to increase in the long-run and competitive renewable energy technologies the introduction of such sustainable power generation system seems a viable and environmental friendly option. Nevertheless the implementation of renewable energies on small islands is quite low based on high transaction costs and missing knowledge according to the market potential. Our work provides a global overview on the small island landscape showing the respective population, economic activity, energy demand, and fuel costs for almost 1800 islands with approximately 20 million inhabitants currently supplied by 15 GW of diesel plants. Based on these parameters a detailed techno-economic assessment of the potential integration of solar PV, wind power, and battery storage into the power supply system was performed for each island. The focus on solar and wind was set due to the lack of data on hydro and geothermal potential for a global island study. It revealed that almost 7.5 GW of photovoltaic and 14 GW of wind power could be economically installed and operated on these islands reducing the GHG-emissions and fuel consumption by approximately 50%. In total numbers more than 20 million tons of GHG emissions can be reduced by avoiding the burning of 7.8 billion liters of diesel per year. Cost savings of around 9 USDct/kWh occur on average by implementing these capacities combined with 5.8 GWh of battery storage. This detailed techno-economic evaluation of renewable energies enables policy makers and investors to facilitate the implementation of clean energy supply systems on small islands. To accelerate the implementation of this enormous potential we give specific policy recommendations such as the introduction of proper regulations. - Highlights: • GIS analysis has identified approximately 1800 small island energy systems with

  1. Three essays of economics and policy on renewable energy and energy efficiency

    Science.gov (United States)

    Meng, Yuxi

    In face of the crisis in energy security, environmental contamination, and climate change, energy saving and carbon emission reduction have become the top concerns of the whole human world. To address those concerns, renewable energy and energy efficiency are the two fields that many countries are paying attention to, which are also my research focus. The dissertation consists of three papers, including the innovation behavior of renewable energy producers, the impact of renewable energy policy on renewable innovation, and the market feedback to energy efficient building benchmarking ordinance. Here are the main conclusions I have reached in this dissertation. First, through the study on foreign patenting intention with the case study of Chinese solar PV industry, I looked at the patenting behaviors of 15 non-Chinese solar PV producers in solar PV technologies in China, and pointed out that foreign firms may file patents in the home country or production base of their competitors in order to earn the competitive edge in the global market. The second study is about the "Innovation by Generating" process. I specifically focused on Renewable Portfolio Standard (RPS) in the United States and the innovation performance within each state, and found out that wind power generation in RPS states has developed rapidly after the adoption of RPS, while the "Innovating by Generating" effect is more significant in solar PV technologies. In general, the innovations of the two technology groups are not prominently encouraged by RPS. My last study is about the benchmarking law and market response in the scenario of Philadelphia Benchmarking Law. By comparing the rental rate of LEED/EnergyStar buildings and ordinary buildings in the city of Philadelphia before and after the adoption of the building energy efficiency benchmarking law, I believe that the passage of Philadelphia Benchmarking Law may be helpful in improving the public awareness and understanding of energy efficiency

    2011-01-01

    Accelerating development in Sub-Saharan Africa will require massive expansion of access to electricity-currently reaching only about one third of households. This paper explores how essential economic development might be reconciled with the need to keep carbon emissions in check. We develop a geographically explicit framework and use spatial modeling and cost estimates from recent engineering studies to determine where stand-alone renewable energy generation is a cost effective alternative to centralized grid supply. Our results suggest that decentralized renewable energy will likely play an important role in expanding rural energy access. However, it will be the lowest cost option for a minority of households in Africa, even when likely cost reductions over the next 20 years are considered. Decentralized renewables are competitive mostly in remote and rural areas, while grid connected supply dominates denser areas where the majority of households reside. These findings underscore the need to decarbonize the fuel mix for centralized power generation as it expands in Africa. - Research highlights: → Expansion of electricity access in Sub-Saharan Africa remains a development priority. → Low carbon options are important to reduce GHG emissions growth and avoid lock-ins. → Spatially explicit cost modeling guides choice of supply options. → Decentralized renewables are lowest cost for a significant minority of households. → Grid supply remains attractive, suggesting focus on decarbonizing centralized supply.

    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.

    This article examines different modes of electrolyzers in two future scenarios of the German energy system. It turns out that hydrolyzers need a high utilization to pay for themselves. An economic operation in 2030 in the scenario of moderate expansion of renewable energies is not possible. At strong expansion the investment is profitable when high revenues from secondary control power provision can be achieved. Generally it is clear that the secondary control power provision and also the direct sales of hydrogen in industry or in the transport sector allows higher revenues than the storage and reconversion.

    Ryan P Thombs

    2017-08-01

    Full Text Available This cross-national study employs a time-series cross-sectional Prais-Winsten regression model with panel-corrected standard errors to examine the relationship between renewable energy consumption and economic growth, and its impact on total carbon dioxide emissions and carbon dioxide emissions per unit of GDP. Findings indicate that renewable energy consumption has its largest negative effect on total carbon emissions and carbon emissions per unit of GDP in low-income countries. Contrary to conventional wisdom, renewable energy has little influence on total carbon dioxide emissions or carbon dioxide emissions per unit of GDP at high levels of GDP per capita. The findings of this study indicate the presence of a “renewable energy paradox,” where economic growth becomes increasingly coupled with carbon emissions at high levels of renewable energy, and the negative effect of economic growth on carbon emissions per unit of GDP lessens as renewable energy increases. These findings suggest that public policy should be directed at deploying renewable energy in developing countries, while focusing on non-or-de-growth strategies accompanied with renewable energy in developed nations.

    This report is one in a series of reports that Idaho National Laboratory and the Joint Institute for Strategic Energy Analysis are publishing that address the technical and economic aspects of nuclear-renewable hybrid energy systems (N-R HESs). This report discusses an analysis of the economic potential of a tightly coupled N-R HES that produces electricity and hydrogen. Both low and high temperature electrolysis options are considered in the analysis. Low-temperature electrolysis requires only electricity to convert water to hydrogen. High temperature electrolysis requires less electricity because it uses both electricity and heat to provide the energy necessary to electrolyze water. The study finds that, to be profitable, the examined high-temperature electrosis and low-temperature electrosis N-R HES configurations that produce hydrogen require higher electricity prices, more electricity price volatility, higher natural gas prices, or higher capacity payments than the reference case values of these parameters considered in this analysis.

    Nowadays, water management in MENA, no longer exclusive to a sectoral issue pertaining to engineering and technical expertise such as irrigation, water supply and water storage, becomes a shared developmental challenge. In order to face an increasingly growing water crisis, attention on balancing the supply and demand for water given the current constraints, needs analysis of conventional and non conventional water resources from a range of perspectives, including considerations about technological dynamics and alternative renewable energies, which are highly recommended. Thanks to engaged technical progress enabling sensitive desalination cost reduction, water crisis could be of lower impacts. For this region being the world leader in desalination technology investments, we are obliged to rexamine the characteristics of alternative renewable energies. To prevent water shortage from being a constraint to economic development and social stability in MENA, we argue brackish water desalination as one of the most promising and viable options, notably in long term for future generations. This paper contains four sections. brackish water characteristics are clarified in section 1. Then in section 2, we focus on factors affecting both desalination costs and desalination implementation costs. A particular attention is spent in section 3 to electro-dialysis reverse (EDR), subsequent capital and O and M costs approximations. Besides, since there is a pressing need for brackish water desalination, which is energy intensive, alternative renewable energies related to desalination technologies are hightlighted in section 4.

    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)

    Tightly coupled nuclear-renewable hybrid energy systems (N-R HESs) are an option that can generate zero-carbon, dispatchable electricity and provide zero-carbon energy for industrial processes at a lower cost than alternatives. N-R HESs are defined as systems that are managed by a single entity and link a nuclear reactor that generates heat, a thermal power cycle for heat to electricity conversion, at least one renewable energy source, and an industrial process that uses thermal and/or electrical energy. This report provides results of an analysis of two N-R HES scenarios. The first is a Texas-synthetic gasoline scenario that includes four subsystems: a nuclear reactor, thermal power cycle, wind power plant, and synthetic gasoline production technology. The second is an Arizona-desalination scenario with its four subsystems a nuclear reactor, thermal power cycle, solar photovoltaics, and a desalination plant. The analysis focuses on the economics of the N-R HESs and how they compare to other options, including configurations without all the subsystems in each N-R HES and alternatives where the energy is provided by natural gas.

    The purpose of this paper is to investigate the short-run and long-run causality between renewable energy (RE) consumption and economic growth (EG) in nine OECD countries from the period between 1982 and 2011. To examine the linkage, this paper uses the autoregressive distributed lag (ARDL) bounds testing approach of cointegration test and vector error-correction models to test the causal relationship between variables. The co-integration and causal relationships are found in five countries-United States of America (USA), Japan, Germany, Italy, and United Kingdom (UK). The overall results indicate that (1) a short-run unidirectional causality runs from EG to RE in Italy and UK; (2) long-run unidirectional causalities run from RE to EG for Germany, Italy, and UK; (3) a long-run unidirectional causality runs from EG to RE in USA, and Japan; (4) both long-run and strong unidirectional causalities run from RE to EG for Germany and UK; and (5) Finally, both long-run and strong unidirectional causalities run from EG to RE in only USA. Further evidence reveals that policies for renewable energy conservation may have no impact on economic growth in France, Denmark, Portugal, and Spain.

  14. Design of an economically efficient feed-in tariff structure for renewable energy development

    2008-01-01

    Evidence suggests, albeit tentatively, that feed-in tariffs (FITs) are more effective than alternative support schemes in promoting renewable energy technologies (RETs). FITs provide long-term financial stability for investors in RETs, which, at the prevailing market price of electricity, are not currently cost-efficient enough to compete with traditional fossil fuel technologies. On the other hand, if not properly designed, FITs can be economically inefficient, as is widely regarded to have been the case under the Public Utility Regulatory Policies Act of 1978 (PURPA). Under PURPA, too high a guaranteed price led to the creation of so-called 'PURPA machines'-poorly performing generating units that could survive financially only because of heavy subsidies that came at the expense of retail customers. Similarly, because of their adverse impacts on retail electricity rates, German FITs have been subject to increasing political pressure from utilities and customers. In this paper, we propose an innovative two-part FIT, consisting of both a capacity payment and a market-based energy payment, which can be used to meet the renewables policy goals of regulators. Our two-part tariff design draws on the strengths of traditional FITs, relies on market mechanisms, is easy to implement, and avoids the problems caused by distorting wholesale energy markets through above-market energy payments. The approach is modeled on forward capacity market designs that have been recently implemented by several regional transmission organizations in the USA to address needs for new generating capacity to ensure system reliability

    This study examines pyrolysis-based electricity generation and ethanol production using various crops and agricultural residuals in Taiwan. It analyzes the net economic and environmental effects within the framework of the Extended Taiwanese Agricultural Sector Model by incorporating ongoing and potential gasoline, coal and GHG (greenhouse gas) prices. The study discusses the effects of agricultural shifts, which have several important implications for the Taiwanese bioenergy development. First, the cost of collecting rice straw is much lower than the production cost of other energy crops, implying that the efficient use of agricultural waste may eventually result in positive social effects in terms of farmers' revenue, the renewable energy supply and GHG emissions offset. Second, farmers with idle land usually suffer a lower steady income. Encouraging the development of the renewable energy industry increases the demand of raw feedstocks, which involves converting the idle land into cultivation and increasing farmers' revenue. Third, agricultural waste is usually burned and emits CO_2, which accelerates the global climate shift. Approximately one third of emissions could be offset by rice straw-based bioenergy in certain cases. Turning this waste into bioenergy, which offsets net GHG emissions, has positive effects on the climate change mitigation. - Highlights: • Pyrolyzing rice straw provides considerable energy supply (max 4.68 billion kWh). • High emission offset when combined with rice straw (max 2.73 million tons). • Affordable government subsidy ($204 million a year). • Collection and transportation costs of wastes could impact the result significantly.

    In this work it has been analysed the potential diffusion of renewable energy sources and co-generation in the Italian market on the basis of the level of maturation of the different technologies, predicted market growth and environmental impacts associated to them. A sensitivity analysis on external costs generated by global climate changes has allowed everybody to assess how possible errors in estimating the potential impact of greenhouse gasses can affect the estimate of the economic performances of different scenarios of energetic development. On the basis of these considerations, it can be outlined a potential doubling of energy production by renewable energies in the next 10 years, with specific reference of small hydroelectric, biogass and eolic power plants.

    The Irish Government is considering its future targets, policy and programmes for renewable energy for the period beyond 2005. This follows a review in 2003 of policy options that identified a number of different measures to stimulate increased deployment of renewable energy generation capacity. This paper expands this review with an economic analysis of renewable energy price support mechanisms in the Irish electricity generation sector. The focus is on three primary price support mechanisms quota obligations, feed in tariffs and competitive tender schemes. The Green-X computer model is utilised to characterise the RES-E potential and costs in Ireland up until, and including, 2020. The results from this dynamic software tool are used to compare the different support mechanisms in terms of total costs to society and the average premium costs relative to the market price for electricity. The results indicate that in achieving a 20% RES-E proportion of gross electricity consumption by 2020, a tender scheme provides the least costs to society over the period 2006-2020 but only in case there is limited or no strategic bidding. Considering, however, strategic bidding, a feed-in tariff can be the more efficient solution. Between the other two support mechanisms, the total costs to society are highest for feed-in-tariffs (FIT) until 2013, at which point the costs for the quota system begin to rise rapidly and overtake FIT in 2014-2020. The paper also provides a sensitivity analysis of the support mechanism calculations by varying default parameters such as the interim (2010) target, the assumed investment risk levels and the amount of biomass co-firing. This analysis shows that a 2010 target of 15% rather than 13.2% generates lower costs for society over the whole period 2006-2020, but higher costs for the RES-E strategy over the period 2006-2010

    Increasing economic activities in developing economies raise demand for energy mainly sourced from conventional sources. The consumption of more conventional energy will have a significant negative impact on the environment. Therefore, attention of policy makers has recently shifted towards the promotion of renewable energy generation and uses across economic activities to ensure low carbon economy. Given the recent scenario, in this paper, we aim to examine the role of renewable energy consumption on the economic output and CO 2 emissions of the next fastest developing economies of the world. The study employs several robust panel econometric models by using annual data from 1990 to 2012. Empirical findings confirm the significant long-run association among the variables. Similarly, results show that renewable energy consumption positively contributes to economic output and has an adverse effect on CO 2 emissions. Given our findings, we suggest policy makers of those economies to initiate further effective policies to promote more renewable energy generation and uses across economic activities to ensure sustainable economic development.

  3. Promotion of electricity from renewable energy in Europe post 2020. The economic benefits of cooperation

    In Europe, the availability of renewable energies, especially from sun and wind, differs significantly across regions. Consequently, cooperation in the deployment of renewable energy among European countries potentially yields substantial efficiency gains. However, in order to achieve the 2020 renewable energy targets for electricity, Member States of the European Union almost purely rely on domestic production. For the period after 2020, a European renewable energy target has not yet been defined, but decarbonization pathways outlined in the Roadmap of the European Commission include renewable energy shares of electricity generation to be 50-60% by 2030. Therefore, we analyze the benefits of cooperation compared to continuing with national renewable energy support after 2020. We use a large-scale dynamic investment and dispatch model of the European electricity system and find that compared to a 2030 CO{sub 2}-only target (-40% compared to 1990 emission levels), electricity system costs increase by 5 to 7% when a European-wide renewable energy target for electricity generation (of around 55%) is additionally implemented. However, these additional costs are lower by 41 to 45% compared to the additional electricity system costs which would arise if the renewable energy target was reached through national support systems (without cooperation). Furthermore, we find that the cooperation gains (i.e., the cost reduction achieved by cooperation) are quite robust: They decrease only slightly when interconnectors are not further extended (compared to today) and depend only slightly on assumptions about investment cost developments of renewable energy technologies. With regard to the practical implementation of cooperation, however, unclear administrative issues and questions concerning the fair sharing of costs and benefits between the Member States represent major obstacles that need to be tackled in order to reach renewable energy targets at the lowest costs possible.

    2017-11-01

    This article aims to investigate the relationship among renewable energy consumption, carbon dioxide (CO 2 ) emissions, and GDP using panel data for 24 Asian countries between 1990 and 2012. Panel cross-sectional dependence tests and unit root test, which considers cross-sectional dependence across countries, are used to ensure that the empirical results are correct. Using the panel cointegration model, the vector error correction model, and the Granger causality test, this paper finds that a long-run equilibrium exists among renewable energy consumption, carbon emission, and GDP. CO 2 emissions have a positive effect on renewable energy consumption in the Philippines, Pakistan, China, Iraq, Yemen, and Saudi Arabia. A 1% increase in GDP will increase renewable energy by 0.64%. Renewable energy is significantly determined by GDP in India, Sri Lanka, the Philippines, Thailand, Turkey, Malaysia, Jordan, United Arab Emirates, Saudi Arabia, and Mongolia. A unidirectional causality runs from GDP to CO 2 emissions, and two bidirectional causal relationships were found between CO 2 emissions and renewable energy consumption and between renewable energy consumption and GDP. The findings can assist governments in curbing pollution from air pollutants, execute energy conservation policy, and reduce unnecessary wastage of energy.

    2013-01-15

    This study analyses the economic relevance of renewable energy in Switzerland. In 2010 the enterprises in the renewable energy sector generated a gross value added of 4.8 bn CHF (equalling 0.9% of Swiss GDP). Employment in this sector approximated 22,800 fulltime jobs (0.6% of total Swiss employment). Including supply chain companies, 1.5% of Swiss GDP and 1.2% of total employment can be related to the use of renewable energy. Exports of renewable energy related goods and services equalled 3.2 bn CHF. Since 2000 the Swiss renewable energy sector has experienced an above-average annual growth of more than 4%. Its potential development until the year 2020 was studied with two scenarios. In the policy scenario, that assumes additional policy measures for renewable energy promotion, direct value added of the renewable energy sector would amount to 6.4 bn CHF (+33%), direct employment would increase to 29,200 fulltime jobs (+28%, gross effects resp.). In the more conservative baseline scenario, growth would be much weaker, but still slightly stronger than anticipated for the average economy. (authors)

    This article investigates the long-run and causal linkages between economic growth, CO 2 emissions, renewable and non-renewable (fossil fuels) energy consumption, the Composite Trade Intensity (CTI) as a proxy for trade openness, and the Chinn-Ito index as a proxy for financial openness for a panel of the Commonwealth of Independent States (CIS) region including Armenia, Azerbaijan, Belarus, Georgia, Kazakhstan, Kyrgyzstan, Moldova, Russia, Tajikistan, Turkmenistan, Ukraine, and Uzbekistan over the period of 1992-2015. It is the first time that CTI and the Chinn-Ito indexes are used in an economic-pollution model. Employing three panel unit root tests, panel cointegration estimation methods (DOLS and FMOLS), and two panel causality tests, the main empirical results provided evidence for the bidirectional long-run relationship between all the variables in all 12 sampled countries except for economic growth-renewable energy use linkage. The findings of causality tests indicated that there is a unidirectional short-run panel causality running from economic growth, financial openness, and trade openness to CO 2 emissions and from fossil fuel energy consumption to renewable energy use.

  7. On the global economic potentials and marginal costs of non-renewable resources and the price of energy commodities

    2013-01-01

    A model is presented in this work for simulating endogenously the evolution of the marginal costs of production of energy carriers from non-renewable resources, their consumption, depletion pathways and timescales. Such marginal costs can be used to simulate the long term average price formation of energy commodities. Drawing on previous work where a global database of energy resource economic potentials was constructed, this work uses cost distributions of non-renewable resources in order to evaluate global flows of energy commodities. A mathematical framework is given to calculate endogenous flows of energy resources given an exogenous commodity price path. This framework can be used in reverse in order to calculate an endogenous marginal cost of production of energy carriers given an exogenous carrier demand. Using rigid price inelastic assumptions independent of the economy, these two approaches generate limiting scenarios that depict extreme use of natural resources. This is useful to characterise the current state and possible uses of remaining non-renewable resources such as fossil fuels and natural uranium. The theory is however designed for use within economic or technology models that allow technology substitutions. In this work, it is implemented in the global power sector model FTT:Power. Policy implications are given. - Highlights: • Theoretical model to forecast marginal costs of non-renewable resources. • Tracks the consumption and costs of non-renewable resources. • For use in economic or technology models

    Electricity is essential for rural development. In 2005, 1.6 billion people, around a quarter of the world's population, living mostly in rural areas of developing countries, had no access to electricity. In general, remote rural areas in developing countries have little prospect of having access to grid-based electricity, which usually only extends to densely populated urban areas, where a large customer base justifies heavy expenditure for electricity infrastructure. One option for electrification in remote rural areas is to decentralize electricity systems based on renewable energy sources. However, such an option is not universally agreed upon. This dissertation examines a renewable energy-based rural electrification program, the 'Township Electrification Program', launched by the Chinese government in 2002. The Program was implemented in 1013 non-electrified townships in remote rural areas of 11 western provinces, providing electricity for 300,000 households and 1.3 million people. And at the time of research, the Program was known as the world's largest renewable energy-based rural electrification program in terms of investment volume ever carried out by a country. Two townships, Saierlong Township in Qinghai Province and Namcuo Township in Tibet Autonomous Region, were selected as cases for an in-depth examination of rural electrification practices in remote rural areas of western China. Both qualitative (interviews, observations, mapping, and transition walk) and quantitative (household survey) methods were applied in the field to collect data. The main findings of the study are summarized as follows: First, political leaders' concern over the unequal economic development of eastern and western China, as well as rural and urban areas, was the main factor triggering inclusion of the policy issue, electricity access in remote rural areas of western China, in the government's policy agenda. Second, like other energy policies, the formulation and adoption of

    The purpose of this project was to expose middle school students to a variety of alternative energy sources with a variety of practical applications. It was part of an Austria-wide IMST-project (IMST stands for innovation makes students strong). As part of this exposure, several classes of about 80 students visited a number of locations for alternative energy resources, including a hydroelectric site, a biological energy plant, a wind turbine manufacturing plant, a water purification station as well as others others. A short film was made to document the project in order that non-participants in the class could also gain knowledge on alternative energy. The three minute film will be shown at the poster.

  12. Economic impacts from the promotion of renewable energy technologies. The German experience

    2010-01-01

    The allure of an environmentally benign, abundant, and cost-effective energy source has led an increasing number of industrialized countries to back public financing of renewable energies. Germany's experience with renewable energy promotion is often cited as a model to be replicated elsewhere, being based on a combination of far-reaching energy and environmental laws that stretch back nearly two decades. This paper critically reviews the centerpiece of this effort, the Renewable Energy Sources Act (EEG), focusing on its costs and the associated implications for job creation and climate protection. We argue that German renewable energy policy, and in particular the adopted feed-in tariff scheme, has failed to harness the market incentives needed to ensure a viable and cost-effective introduction of renewable energies into the country's energy portfolio. To the contrary, the government's support mechanisms have in many respects subverted these incentives, resulting in massive expenditures that show little long-term promise for stimulating the economy, protecting the environment, or increasing energy security.

    2014-07-01

    Full Text Available The coming interaction between a growing electrified vehicle fleet and the desired growth in renewable energy provides new insights into the economic dispatch (ED problem. This paper presents an economic dispatch model that considers electric vehicle charging, battery exchange stations, and wind farms. This ED model is a high-dimensional, non-linear, and stochastic problem and its solution requires powerful methods. A new finite action-set learning automata (FALA-based approach that has the ability to adapt to a stochastic environment is proposed. The feasibility of the proposed approach is demonstrated in a modified IEEE 30 bus system. It is compared with continuous action-set learning automata and particle swarm optimization-based approaches in terms of convergence characteristics, computational efficiency, and solution quality. Simulation results show that the proposed FALA-based approach was indeed capable of more efficiently obtaining the approximately optimal solution. In addition, by using an optimal dispatch schedule for the interaction between electric vehicle stations and power systems, it is possible to reduce the gap between demand and power generation at different times of the day.

    2013-01-01

    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

    This information paper accompanies the IEA publication Deploying Renewables 2011: Best and Future Policy Practice (IEA, 2011a). It provides more detailed data and analysis on policies for Deploying Renewables, and is intended to complement the main publication. It provides an account of the strategic drivers underpinning renewable energy (RE) technology deployment (energy security, economic development and environment protection) and assesses RE technologies with respect to these drivers, including an estimate of GHG emissions reductions due to RE technologies. The paper also explores the different barriers to deploying renewables at a given stage of market maturity and discusses what tools policy makers can avail of to succeed in removing deployment barriers. An additional topical highlight explores the challenges associated with accelerating the diffusion of RE technologies in developing countries.

  2. What drives renewable energy development?

    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.

    In this paper we identify the renewable energy source (RES) demand scenarios for Morocco, the needs of RES installed capacity according to those scenarios and the detailed investment plans needed to achieve such installed capacity supply. Then, using a dynamic variant input–output model, we simulate the macroeconomic impact of the foreign investment inflows needed to make available these Moroccan RES generation capacity plans in the medium and long term. The use of concentrated solar plants, photovoltaic generation and wind power farms are considered and compared in the simulation. - Highlights: ► An evaluation of RES economic impact in Morocco from 2010 to 2040 is simulated. ► Different scenarios about import dependency and energy exports have been considered. ► The impact on GDP range from 1.21% to 1.99%. ► The impact on employment range from 269 to 499 thousand jobs. ► The alternative that produces most benefits would be the installation of windmills.

    Hydrogen is seen by many as a key energetic vector for the 21{sup st} century. Its utilization in fuel cells enables a clean and efficient production of electricity. The possibility to obtain hydrogen from various sources, along with several types of potential applications of fuel cells, have called the attention and investment of developed countries. European Union, United States, Canada and Japan have important programs that establish tied goals for the utilization of fuel cells in transport and distributed energy generation. Aware of the importance of this technology for the energetic future of Brazil, IPEN started 13 years ago the development of fuel cells for stationary and distributed energy applications. Preliminary studies were carried out at the Materials Research Center due to IPEN expertise on nuclear materials development. Based on both, the good initial results and the proposition of the Brazilian Fuel Cell Program (ProH{sub 2} ) by the Ministry of 2 Science, Technology and Innovation (MCTI), IPEN decided to organize an institutional program on the subject, conducted at the Fuel Cell and Hydrogen Center - CCCH. The objectives of the IPEN/CCCH program are based on the MCTI national program, contributing significantly to the national development in this area. The R and D Program was structured in a cross-cutting way involving human and infrastructure resources from many IPEN technical departments. The Center comprises three main areas of interests: PEMFC (Proton Exchange Membrane Fuel Cell); SOFC (Solid Oxide Fuel Cell); and H{sup 2}-Production, mainly from ethanol reforming. More than 50 professionals were engaged at this development, although some in part time, including PhDs, MSc and graduate students and undergraduate students. Important scientific and technological results have been obtained and the main achievements can be evaluated by patents, published papers, graduate courses given and the graduate student's thesis concluded.

    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

  7. Causal Dynamic Relationships between Political–Economic Factors and Export Performance in the Renewable Energy Technologies Market

    Full Text Available This study explores how political–economic forces could affect export performance in the renewable energy technologies market. We conduct panel framework analyses to verify the characteristics of panel data for 19 countries before establishing the panel estimator meant to test the effects of political–economic forces on export specialization. We consider the results of the panel framework analyses and develop an empirical model to test casual dynamic relationships between political–economic forces and export performance. The results from the least squares dummy variable-corrected estimation indicate that the major factors promoting the export specialization of renewable energy technologies are, in order of decreasing importance, public pressure, market size, and government demand-pull policy. However, the traditional energy industry has no significant effect on export performance. Finally, this study finds that dynamic effects exist in all estimations.

    The author summarizes changes which have occurred in Bolivia in the past year which have had an impact on renewable energy source development. Political changes have included the privatization of power generation and power distribution, and resulted in a new role for state level government and participation by the individual. A National Rural Electrification Plan was adopted in 1996, which stresses the use of GIS analysis and emphasizes factors such as off grid, economic index, population density, maintenance risk, and local organizational structure. The USAID program has chosen to stress economic development, environmental programs, and health over village power programs. The national renewables program has adopted a new development direction, with state projects, geothermal projects, and private sector involvement stressed.

    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

    In the determination of the potential of renewable energy two factors are important: (1) macro-economical consequences for the Netherlands because of the use of renewable energy sources, and (2) the possibilities of renewable energy to fulfil the energy demands of the several sectors. The main question to be answered in this report is: What is the maximum quantity of renewable energy that can be realized in 2050? The answer will be expressed in the percentage of renewable energy in relation to the total secondary energy demand (excluding non-energetic use of energy carriers). The aim is, that 50% of the energy supply is produced by renewable energy sources. The quantity is eventually determined by the influence of these renewable energy options on the macro-economical position of the Netherlands and the extent to which renewable energy supply meets the energy demands of the several sectors. The macro-economical consequences are determined on the basis of the cost and sensitivities of the several renewable energy options in 2050. Subquestions to answer the main question concern energy demand, renewable energy options, multi-criteria analysis and contemplation. The energy demand in 2050 and the energy profiles of the sectoral energy demand of secondary energy carriers are determined. The renewable energy options, wind energy (onshore and offshore), bioenergy, photovoltaic energy and thermal solar energy, heat pumps and import of green electricity and biomass, are investigated on several factors: Maximal realizable potential; Cost (Cost reduction until 2050, Investment cost, O and M-cost and fuel cost, Total cost, Out of pocket cost); Need for energy storage and cost for fitting in the energy grid; Integration with other renewable energy sources; Availability in sectors; Sensitivity analysis. These data are used in a multi-criteria analysis with four quantitative criteria. The results of this multi-criteria analysis are combined with qualitative criteria with regard

    Highlights: • Batteries and pumped hydro storage schemes are examined. • Sizing procedure for each option is investigated in detail. • The two schemes are compared in terms of life cycle cost and technical viability. • Sensitivity analyses are conducted on five key input parameters. - Abstract: This study examined and compared two energy storage technologies, i.e. batteries and pumped hydro storage (PHS), for the renewable energy powered microgrid power supply system on a remote island in Hong Kong. The problems of energy storage for off-grid renewable energy were analyzed. The sizing methods and economic models were developed, and finally applied in the real project (case study). The results provide the most suitable energy storage scheme for local decision-makers. The two storage schemes were further divided into 4 options. Accordingly, the life-cycle costs (LCC), levelized costs for the renewable energy storage system (LCRES) and the LCC ratios between all options were calculated and compared. It was found that the employment of conventional battery (Option 2) had a higher LCC value than the advanced deep cycle battery (Option 1), indicating that using deep cycle batteries is more suitable for a standalone renewable power supply system. The pumped storage combined with battery bank option (Option 3) had only 55% LCC of that of Option 1, making this combined option more cost-competitive than the sole battery option. The economic benefit of pumped storage is even more significant in the case of purely pumped storage with a hydraulic controller (Option 4), with the lowest LCC among all options at 29–48% of Option 1. Sensitivity analysis demonstrates that PHS is even more cost competitive by controlling some adjustments such as increasing energy storage capacity and days of autonomy. Therefore, the renewable energy system coupled with pumped storage presents technically feasible opportunities and practical potential for continuous power supply in remote

    Highlights: • We present a MILP to co-optimize generation, transmission, and storage investments. • We find significant value in co-optimized storage via investment deferrals. • Operational savings from bulk services are small relative to investment deferrals. • Co-optimized energy storage significantly reduces prices associated with RPS. - Abstract: Worldwide, environmental regulations such as Renewable Portfolio Standards (RPSs) are being broadly adopted to promote renewable energy investments. With corresponding increases in renewable energy deployments, there is growing interest in grid-scale energy storage systems (ESS) to provide the flexibility needed to efficiently deliver renewable power to consumers. Our contribution in this paper is to introduce a unified generation, transmission, and bulk ESS expansion planning model subject to an RPS constraint, formulated as a two-stage stochastic mixed-integer linear program (MILP) optimization model, which we then use to study the impact of co-optimization and evaluate the economic interaction between investments in these three asset classes in achieving high renewable penetrations. We present numerical case studies using the 24-bus IEEE RTS-96 test system considering wind and solar as available renewable energy resources, and demonstrate that up to $180 million/yr in total cost savings can result from the co-optimization of all three assets, relative to a situation in which no ESS investment options are available. Surprisingly, we find that co-optimized bulk ESS investments provide significant economic value through investment deferrals in transmission and generation capacity, but very little savings in operational cost. Finally, we observe that planning transmission and generation infrastructure first and later optimizing ESS investments—as is common in industry—captures at most 1.7% ($3 million/yr) of the savings that result from co-optimizing all assets simultaneously.

    2017-12-01

    Context/Purpose: Power generation from renewable energy (RE) could substitute huge amount of fossil energy in the power sector and have substantial co-benefits of air quality and human health improvement. In 2016, China National Renewable Energy Center (CNREC) released China Renewable Energy Outlook, CREO2016 and CREO2017, towards 2030 and 2050, respectively, in which two scenarios are proposed, namely, a conservative "Stated Policy" scenario and a more ambitious "High RE" scenario. This study, together with CNREC, aims to quantify the health and economic benefits of developing renewable energy at the provincial level in China up to 2030 and 2050. Methods: For this purpose, we developed an integrated approach that combines a power dispatch model at CNREC, an air pollutant emission projection model using energy consumption data from the Long-range Energy Alternatives Planning System (LEAP) model, an air quality model (GEOS-Chem at Harvard), an own-developed health model, and a macro economic model (Computable General Equilibrium model). Results: All together, we attempt to quantify how developing RE could reduce the concentration of PM2.5 and ozone in 30 provinces of China, how the human health could be improved in terms of mortality, morbidity and work hour loss, and what is the economic value of the health improvement in terms of increased GDP and the value of statistical life lost. The results show that developing RE as stated in the CREO2016 could prevent chronic mortality of 286 thousand people in China in 2030 alone, the value of saved statistical life is worthy 1200 billion Yuan, equivalent to 1.2% of GDP. In addition, averagely, due to reduced mortality and improved morbidity each person could work additionally by 1.16 hours per year, this could contribute to an increase of GDP by 0.1% in 2030. The assessment up to 2050 is still underway. Interpretation: The results imply that when the external benefit of renewable energy is taken into account, RE could be

    2009-01-01

    This paper uses a panel threshold regression (PTR) model to investigate the influence that energy prices have on renewable energy development under different economic growth rate regimes. The empirical data are obtained from each of the OECD member-countries over the period from 1997 to 2006. We show that there is one threshold in the regression relationship, which is 4.13% of a one-period lag in the annual gross domestic product (GDP) growth rate. The consumer price index (CPI), in so far as it relates to variations in energy, is significantly positively correlated with the contribution of renewables to energy supply in the regime with higher-economic growth, but there is no relationship in the regime with lower economic growth. Therefore, countries characterized by high-economic growth are able to respond to high energy prices with increases in renewable energy use, while countries characterized by low-economic growth countries tend to be unresponsive to energy price changes when they come to their level of renewable energy.

    Further development of the North-East Asian energy system is at a crossroads due to severe limitations of the current conventional energy based system. For North-East Asia it is proposed that the excellent solar and wind resources of the Gobi desert could enable the transformation towards a 100% renewable energy system. An hourly resolved model describes an energy system for North-East Asia, subdivided into 14 regions interconnected by high voltage direct current (HVDC) transmission grids. Simulations are made for highly centralized, decentralized and country-wide grids scenarios. The results for total system levelized cost of electricity (LCOE) are 0.065 and 0.081 €/(kW·h) for the centralized and decentralized approaches for 2030 assumptions. The presented results for 100% renewable resources-based energy systems are lower in LCOE by about 30-40% than recent findings in Europe for conventional alternatives. This research clearly indicates that a 100% renewable resources-based energy system is THE real policy option.

    Full Text Available Energy production based on fossil fuel reserves is largely responsible for carbon emissions, and hence global warming. The planet needs concerted action to reduce fossil fuel usage and to implement carbon mitigation measures. Ocean energy has huge potential, but there are major interdisciplinary problems to be overcome regarding technology, cost reduction, investment, environmental impact, governance, and so forth. This article briefly reviews ocean energy production from offshore wind, tidal stream, ocean current, tidal range, wave, thermal, salinity gradients, and biomass sources. Future areas of research and development are outlined that could make exploitation of the marine renewable energy (MRE seascape a viable proposition; these areas include energy storage, advanced materials, robotics, and informatics. The article concludes with a sustainability perspective on the MRE seascape encompassing ethics, legislation, the regulatory environment, governance and consenting, economic, social, and environmental constraints. A new generation of engineers is needed with the ingenuity and spirit of adventure to meet the global challenge posed by MRE.

    This paper analyzes dynamic economies in renewable energy technologies. The paper has two contributions. The first is to test the robustness of experience in solar photovoltaic, solar thermal and wind energy to the addition of an explicit time trend, which has been done in experience studies for other industries, but not for renewable energy technologies. Estimation is carried out on the assumption that cumulative capacity, industry production, average firm production, and electricity generation affect experience and thus the fall in price. The second contribution is to test the impact of R and D on price reduction. In general cumulative experience is found to be highly statistically significant when estimated alone, and highly statistically insignificant when time is added to the model. The effect of R and D is small and statistically significant in solar photovoltaic technology and statistically insignificant in solar thermal and wind technologies

    Renewable Energy Resources is a numerate and quantitative text covering the full range of renewable energy technologies and their implementation worldwide. Energy supplies from renewables (such as from biofuels, solar heat, photovoltaics, wind, hydro, wave, tidal, geothermal, and ocean-thermal) are essential components of every nation's energy strategy, not least because of concerns for the local and global environment, for energy security and for sustainability. Thus in the years between the first and this third edition, most renewable energy technologies have grown from fledgling impact to s

    2011-01-01

    There is strong growth in the demand for energy resources across the diverse French administered overseas territories and departments (hereinafter the 'Overseas'). This demand should not be brought into conflict with the policies needed to control consumption and improve energy efficiency. The overseas territories are currently at a 'catch up' stage in terms of this significant and growing legitimate social demand. The overseas territories, which must import all of their oil, gas and coal, have considerable renewable energy resources, which in many cases have been developed with some success. These resources are of a more varied nature than those in metropolitan France. While the demand should continue to grow, the Overseas have set an objective of energy self-sufficiency for 2030. In many respects, the overseas territories are something of a laboratory for the development of renewable energies. The diversity of their natural environments facilitates experimentation in all the modes of production under real conditions. The potential of the Overseas in this regard, its role as a laboratory for energy sources that will be part our future energy supply, along with the industrial issues as regards exporting national expertise, justify drawing attention to the experiences in these territories and funding an original energy system, the creation of which falls to the Overseas

    Highlights: • Open question if renewables achieve both environmental and socioeconomic objectives. • Two policies each assessed looking at energy access and employment respectively. • Important role of governments and need for monitoring capacity is confirmed. • Short-term socioeconomic benefits realized in two cases, but they may not sustain. • Cases underline need for methodologies to better assess multiple-objective policies. - Abstract: The Green Economy (GE) paradigm aims to reconcile environmental and socio-economic objectives. Policies to deploy renewable energy (RE) are widely perceived as a way to tap the potential synergies of these objectives. It is, however, still largely unclear whether the potential of simultaneously achieving both environmental and socio-economic objectives can be fully realized, and whether and how multiple objectives influence policy design, implementation, and evaluation. We aim to contribute to this aspect of GE research by looking at selected country experiences of renewable energy deployment with respect to the socio-economic goals of job creation or energy access. Across the cases examined, we find the following implications of relevance for the GE framework: First, we confirm the important role of governmental action for GE, with the specific need to state objectives clearly and build monitoring capacity. Second, consistent with the “strong” green growth variant of GE, some of the cases suggest that while renewable deployment may indeed lead to short-term socio-economic benefits, these benefits may not last. Third, we underline the urgent need for new methodologies to analyze and better understand multiple-objective policies, which are at the heart of the GE paradigm.

  11. Technical and economic viability of electric power plants on the basis of renewable energy resources regarding hierarchical structure

    Directory of Open Access Journals (Sweden)

    Balzannikov Mikhail

    2017-01-01

    Full Text Available The article deals with power stations working on the basis of non-renewable energy resources and finite resources which will inevitably come to depletion in the future. These installations produce considerable negative impact on the environment, including air pollution. It is noted that considerable amounts of emissions of harmful substances accounts for the share of small thermal installations which aren’t always considered in calculations of pollution. The author specifies that emission reduction of harmful substances should be achieved due to wider use of environmentally friendly renewable energy resources. It is recommended to use hierarchical structure with the priority of ecological and social conditions of the region for technical and economic viability of consumers’ power supply systems and installations, based on renewable energy resources use. At the same time the author suggests considering federal, regional and object levels of viability. It is recommended to consider the main stages of lifecycle of an object for object level: designing, construction, operation, reconstruction of an object and its preservation. The author shows the example of calculation of power plant efficiency, based on renewable energy resources during its reconstruction, followed by power generation increase.

    This paper investigates how large-scale energystorage can assist the integration of fluctuatingrenewableenergy by using the Irish energy system, pumped hydroelectric energystorage (PHES), and wind power as a case study. In total three key aspects were investigated in relation to PHES: its operation...... are sensitive to changes in the PHES capacities used, fuel prices, interest rates, and the total annual wind energy produced. Finally, the optimum capacities of PHES identified for Ireland in 2020 were compared to two other alternatives which required the same investment: domestic heat pumps and district......, size, and cost. From the results it was evident that PHES can increase the wind penetration feasible on the Irish energy system and also reduce its operating costs. However, under predicted 2020 fuel prices and a conventional 6% interest rate, these savings may not be sufficient since the savings...

    Renewable sources represent an effective alternative to fossil fuels for preventing resources depletion and for reducing air pollution. However, their diffusion requires huge capital investment and major infrastructure changes, which have to be assessed to verify their effectiveness. The article present an application of the R-MARKAL model to investigate the feasibility of renewable use on a local case study for electricity and thermal energy production. A comprehensive modelling approach is used to emphasise the relationships and feedback between conversion and demand sectors (residential, services and commercial), taking into account contemporaneously legal issues and physical limits of the system. The model's solutions represent the minimum cost choice and the results show that even in absence of erogenous environmental constraints, many renewable technologies are profitable demand device and their investment costs are paid off in a medium term by lower operating and maintenance expenditures. In this context the use of thermal energy from incinerator allows one to achieve a consistent reduction of atmospheric pollutant emissions and, particularly, of greenhouse gases emissions due to waste degradation.

    Import of renewable energy from biomass by the Netherlands is expected to be necessary to meet the objective for renewable energy set by the Dutch government. However, this import does not take place yet and there are many possibilities for import because several countries may serve as a supplier of biomass, there are several types of biomass available in these countries and this biomass can be transported to the Netherlands in many ways. Analysis is necessary to find out what are the best possibilities for import of renewable energy from biomass by the Netherlands. In this study the import of energy, produced in Sweden from biomass, by the Netherlands is analyzed. Sweden is selected as the biomass supplying country because it is expected to have a large potential of biomass. The aspects studied are costs and macro-economic effects (increase in employment and value added caused by the import operation). The objectives are: (1) Selection of likely export chains based on the different sources of biomass for energy in Sweden and the different energy carriers that can be exported; (1) Calculation of the costs for the delivery of 1 kWh of electricity to the main grid in the Netherlands for each chain, for the present and for the year 2010; (3) Calculation of macro-economic effects (changes in employment and value added) in Sweden and the Netherlands for the import of 10 PJ of energy from biomass per year for each chain; (4) Comparison of the chains based on both costs and macro-economic effects; and (5) Discussion of the method and recommendations for simplifications for application in situations with a lower data quality. 45 refs

    This final report for WWF Switzerland, Greenpeace Switzerland, the Swiss Energy Foundation SES, Pro Natura and the Swiss Cantons of Basel City and Geneva takes a look at the energy-relevant effects of the propositions made by Swiss electricity utilities for large-scale power generation. These proposals are compared with a strategy that proposes investments in energy-efficiency and the use of renewable sources of energy. The effects of both scenarios on the environment and the risks involved are discussed, as are the investments involved. The associated effects on the Swiss national economy are also discussed. For the efficiency and renewables scenario, two implementation variants are discussed: Inland investments and production are examined as are foreign production options and/or import from foreign countries. The methods used in the study are introduced and discussed. Investment and cost considerations, earnings and effects on employment are also reviewed. The report is completed with an extensive appendix which, amongst other things, includes potential reviews, cost estimates and a discussion on 'smart grids'

    Full Text Available Meeting rapidly growing global energy demand—without producing greenhouse gases or further diminishing the availability of non-renewable resources—requires the development of affordable low-emission renewable energy systems. Here, we develop a hybrid renewable energy system (HRES for automotive applications—specifically, a roof-installed photovoltaic (PV array combined with a PEM fuel cell/NiCd battery bus currently operating shuttle routes on the University of Delaware campus. The system’s overall operating objectives—meeting the total power demand of the bus and maintaining the desired state of charge (SOC of the NiCd battery—are achieved with appropriately designed controllers: a logic-based “algebraic controller” and a standard PI controller. The design, implementation, and performance of the hybrid system are demonstrated via simulation of real shuttle runs under various operating conditions. The results show that both control strategies perform equally well in enabling the HRES to meet its objectives under typical operating conditions, and under sudden cloud cover conditions; however, at consistently high bus speeds, battery SOC maintenance is better, and the system consumes less hydrogen, with PI control. An economic analysis of the PV investment necessary to realize the HRES design objectives indicates a return on investment of approximately 30% (a slight, but nonetheless positive, ~$550 profit over the bus lifetime in Newark, DE, establishing the economic viability of the proposed addition of a PV array to the existing University of Delaware fuel cell/battery bus.

    2018-05-01

    The present study explores the impact of economic growth; urban expansion; and consumption of fossil fuels, solid fuels, and renewable energy on environmental degradation in developing economies of Sub-Saharan Africa. To demonstrate its findings in detail, the study adopts a system generalized method of moment (GMM) on a panel of 34 emerging economies for the period from 1995 to 2015. The results describe that the consumption of fossil and solid fuels for cooking and expansion of urban areas are significantly contributing to carbon dioxide emissions, on one end, and stimulating air pollution, on the other. The results also exhibit an inverted U-shape relationship between per capita economic growth and carbon emissions. This relation confirms the existence of an environmental Kuznets curve (EKC) in middle- and low-income economies of Sub-Saharan Africa. Furthermore, the findings reveal that the use of renewable energy alternatives improves air quality by controlling carbon emissions and lowering the direct interaction of households with toxic gases. Thus, the use of renewable energy alternatives helps the economies to achieve sustainable development targets.

    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.

    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)

    In this book, the author describes how renewable energies have been developed in a way he considers as scandalous, whereas they are a technical, financial and ecological dead end. He also explains how ecologists (notably the ADEME) manipulate figures to make believe that these energies could be an answer to the needs of France, of Europe and of humanity. In a first chapter, he criticises the influence of a so-called green ideology on the design of energy transition. In the second one, he denounces twelve tales about energy transition. In the next chapters, he denounces the sham of renewable energies, and finally tells some unfortunate renewable experiments

    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.

  15. Economic competitiveness of electricity production means inside smart grids: application to nuclear energy and variable renewable energies

    International Nuclear Information System (INIS)

    Keppler, J.H.; Baritaud, M.; Berthelemy, M.

    2017-01-01

    For a long time the comparison of the production costs of electricity from various primary sources were made on the basis of levelised costs of electricity (LCOE). LCOE is in fact the cost of the technology used for the production. In recent years solar and wind energies have seen their LCOE drop sharply (-60 % for solar power in 5 years) while nuclear energy's LCOE is now stabilized. In order to assess the cost of renewable energies, LCOE are not sufficient because variable energies like solar or wind power require other means of production to compensate their variability. Another point is that renewable energies are decentralized and as a consequence require investments to develop the power distribution system. This analysis presents a new methodology to compare the costs of electricity production means. This methodology takes into account LCOE and a system cost that represents the cost of the effects of the technology on the rest of the electricity production system. (A.C.)

    2018-01-01

    This study aims to examine the impact of renewable and non-renewable energy consumption on the agriculture, industry, services, and overall economic activities (GDP) across a panel of G20 nations. The study makes use of annual data from 1980 to 2012 on 17 countries of the G20. To achieve the study objectives, we apply several robust panel econometric models which account for cross-sectional dependence and heterogeneity in the analysis. The empirical findings confirm the significant long-run equilibrium relationship among the variables. The long-run elasticities indicate that both renewable and non-renewable energy consumptions have significant positive effect on the economic activities across the sectors and also on the overall economic output. These results also imply that the impact is more from renewable energy on economic activities than that of non-renewable energy. Given that, our results offer significant policy implications. We suggest that the policy makers should aim to initiate effective policies to turn domestic and foreign investments into renewable energy projects. This eventually ensures low carbon emissions and sustainable economic development across the G20 nations.

  17. Renewable energy in Europe

    International Nuclear Information System (INIS)

    Deshaies, M.

    2009-01-01

    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.

    Full Text Available Deficiency in energy sector is a major problem, which can hinder the development workflow of any country. Being the eighth most populated country in the world with a total electricity generation of only about 5000 MW and consumption of 144 kWh per capita, Bangladesh is one of the most electricity-deprived countries around the globe. In addition, absence of adequate investment and mass people awareness is a major problem in this country. Therefore, it would be very difficult to achieve overall progress without ensuring energy security by utilizing the promising renewable energy sources. In order to achieve the Millennium Development Goal (MDG, it is must for a third world country like Bangladesh to address the issue of energy deficiency promptly. In this context, renewable energy is the sustainable solution of energy security as well as social, environmental and economical problems. This paper summarizes the current energy scenario of Bangladesh, impacts of pollution from conventional energy sources, prospects of renewable energy development, and estimates the total investment required in Bangladesh to promote renewable energy sector by the year 2020.

    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 importance of renewable energy in energy systems is increasing at an impressive rate, and the expectation is that this tendency will continue in the longer term. As a consequence, there is a strong need for reliable insight into the employment benefits from renewable energy. The current knowledge on the economic impacts of large-scale deployment of renewable energy technologies is more or less derived on an ad hoc basis and consists of a variety of different methodologies with different objectives. This is why the International Energy Agency's Implementing Agreement on Renewable Energy Technology Deployment (IEA-RETD) would like to facilitate a more structural approach, which will contribute to reliable and consistent insights of employment effects from deployment of renewable energy technologies. The objectives of the EMPLOY-EID project are to: Provide guidelines based on a thorough review of best practices, which are able to contribute to a consistent, reliable framework in which to measure employment effects from renewable energy deployment and which can be replicated from one country to another; Identify data sources and/or inputs required in application of such guidelines; Provide better understanding of key parameters and mechanisms that determine contribution of renewable energy employment; Assess availability of sources for employment benefit data for all RETD member countries as well as other interesting countries; Provide concrete gross employment benefit data to countries where data is available through application of the guidelines and best practices; and, Document the economic effects of renewable energy deployment through a publishable brochure of the main project results, presentations, the guidelines and background report.

    Highlights: • Uninterrupted energy in an emergency blackout situation. • System modeling of a solar–hydrogen based hybrid renewable energy system. • A comprehensive thermodynamical analysis. • Levelized cost of electricity analysis for a project lifetime of 25 years. - Abstract: A hybrid (Solar–Hydrogen) stand-alone renewable energy system that consists of photovoltaic panels (PV), Proton Exchange Membrane (PEM) fuel cells, PEM based electrolyzers and hydrogen storage is investigated by developing a complete model of the system using TRNSYS. The PV panels are mounted on a tiltable platform to improve the performance of the system by monthly adjustments of the tilt angle. The total area of the PV panels is 300 m 2 , the PEM fuel cell capacity is 5 kW, and the hydrogen storage is at 55 bars pressure and with 45 m 3 capacity. The main goal of this study is to verify that the system meets the electrical power demand of the emergency room without experiencing a shortage for a complete year in an emergency blackout situation. For this purpose, after modeling the system, energy and exergy analyses for the hydrogen cycle of the system for a complete year are performed, and the energy and exergy efficiencies are found as 4.06% and 4.25%, respectively. Furthermore, an economic analysis is performed for a project lifetime of 25 years based on Levelized Cost of Electricity (LCE), and the LCE is calculated as 0.626 $/kWh.

  5. The economic value of transportation energy contingency planning: An objective model for analyzing the economics of domestic renewable energy for supply augmentation

    Science.gov (United States)

    Shaten, Richard Jay

    1998-12-01

    Petroleum provides 90% of transportation energy needs. Domestic production is decreasing and global demand is increasing. Risk of escalating prices and supply interruptions are compounded by environmental and military externalities and lost opportunities from the failure to develop alternative domestic resources. Within the context of "energy contingency planning" municipalities should evaluate crisis mitigation strategies. Supply augmentation using domestic renewable fuels is proposed to avert future financial liabilities. A method for calculating the economic value of this strategy is demonstrated. An objective function and associated constraints represent the cost of preparing for each of three possible scenarios: status quo, inflationary and crisis. Constraints ensure that municipal fuel needs are met. Environmental costs may be included. Optimal solutions determine the fuel supply mix for each scenario. A 3 x 3 matrix presents the range of actual costs resulting from preparing for each scenario and subsequent three possible outcomes. The distribution of probabilities of the outcomes is applied to the cost matrix and an "expected value" of preparing for each scenario is calculated. An unanticipated crisis outcome results in. The expected value of the cost of preparing for a crisis is cast as an insurance premium against potential economic liability. Policy makers accept the crisis preparation fuel mix if: (a) they agree with the calculated penalty cost, or (b) they accept the burden of the insurance premium. Green Bay Wisconsin was chosen as a sample municipality. Results show that a perceived 10% chance of crisis requires an annual tax of 4.00 per household to avert economic impacts of 50 million. At a perceived 50% chance of crisis preparing for the crisis would begin to save the municipality money.

    An economic analysis of biomass power generation was conducted. Two key technologies--direct combustion with a steam turbine and gasification with a syngas engine--were mainly examined. In view of the present domestic biomass infrastructure of Korea, a small and distributed power generation system ranging from 0.5 to 5 MW(e) was considered. It was found that gasification with a syngas engine becomes more economically feasible as the plant size decreases. Changes in the economic feasibilities with and without RPS or heat sales were also investigated. A sensitivity analysis of each system was conducted for representative parameters. Regarding the cost of electricity generation, electrical efficiency and fuel cost significantly affect both direct combustion and gasification systems. Regarding the internal rate of return (IRR), the heat sales price becomes important for obtaining a higher IRR, followed by power generation capacity and electrical efficiency.

    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

    The generally acknowledged sources of renewable energy are wind, geothermal, biomass, solar, hydropower, and hydrogen. Renewable energy technologies are crucial to the production and utilization of energy from these regenerative and virtually inexhaustible sources. Furthermore, renewable energy technologies provide benefits beyond the establishment of sustainable energy resources. For example, these technologies produce negligible amounts of greenhouse gases and other pollutants in providing energy, and they exploit domestically available energy sources, thereby reducing our dependence on both the importation of fossil fuels and the use of nuclear fuels. The market price of renewable energy technologies does not reflect the economic value of these added benefits.

    There is a growing amount of evidence that indicates that fuel cells might be commercially attractive in several market niches in Latin America; however, political approval of demonstration projects has been elusive. In this paper, the results of an economic study carried out on the assumption of introducing an environmentally friendly fuel, such as methanol, for feeding fuel cell systems for electricity generation and heat production in the six bases that Argentina has in Antarctica are reported. It is seen that, in this particular case, there is a net cost benefit, even if the assets resulting from diminishing pollution in Antarctica are not taken into account. (Author)

    2004-01-01

    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)

    The use of renewable energy is tightly connected to solving social problems in Estonia by creating more new jobs. It is essential that Estonia should increase the use of biofuels. One of the biofuels, firewood, has been used already for centuries. For wider use of renewable energy in Estonia, it is not enough to rely only on enterprices. Rather, before any serious progress can take place, the state should create the appropriate legal environment. Due to its many social and environmental aspects, renewable energy is more important to the state than a sole enterprice. Unfortunately, Estonian government has been delaying its duties. Estonia has two resources that should be taken advantage of, fertile spare land and people still used to the country life. The country people would get work by growing different energy crops on the spare land. (author)

  1. Socio-economic and Engineering Assessments of Renewable Energy Cost Reduction Potential

    Science.gov (United States)

    Seel, Joachim

    This dissertation combines three perspectives on the potential of cost reductions of renewable energy--a relevant topic, as high energy costs have traditionally been cited as major reason to vindicate developments of fossil fuel and nuclear power plants, and to justify financial support mechanisms and special incentives for renewable energy generators. First, I highlight the role of market and policy drivers in an international comparison of upfront capital expenses of residential photovoltaic systems in Germany and the United States that result in price differences of a factor of two and suggest cost reduction opportunities. In a second article I examine engineering approaches and siting considerations of large-scale photovoltaic projects in the United States that enable substantial system performance increases and allow thus for lower energy costs on a levelized basis. Finally, I investigate future cost reduction options of wind energy, ranging from capital expenses, operating expenses, and performance over a project's lifetime to financing costs. The assessment shows both substantial further cost decline potential for mature technologies like land-based turbines, nascent technologies like fixed-bottom offshore turbines, and experimental technologies like floating offshore turbines. The following paragraphs summarize each analysis: International upfront capital cost comparison of residential solar systems: Residential photovoltaic (PV) systems were twice as expensive in the United States as in Germany in 2012. This price discrepancy stems primarily from differences in non-hardware or "soft" costs between the two countries, of which only 35% be explained by differences in cumulative market size and associated learning. A survey of German PV installers was deployed to collect granular data on PV soft costs in Germany, and the results are compared to those of a similar survey of U.S. PV installers. Non-module hardware costs and all analyzed soft costs are lower in

    This study examines the possible evolution of Victorian energy markets over the 1998-2030 period from technical, economic and environmental perspectives. The focus is on the technical and economic potential over the study period for renewable energy and energy efficiency to increase their share of energy markets, through their economic competitiveness with the non-renewables of oil, gas and fossil fulled electricity. The study identifies a range of energy options that have a lower impact on carbon dioxide emissions that current projections for the Victorian energy sector, together with the savings in energy, dollars and carbon dioxide emissions. In addition the macroeconomic implications of the energy paths are estimated. Specifically it examines a scenario (R-efficient renewable) where energy efficiency and renewable energy sources realise their estimated economic potential to displace non-renewable energy over the 1988-2030 period. In addition, a scenario (T-Toronto) is examined where energy markets are pushed somewhat harder, but again on an economic basis, so that what is called the Toronto target of reducing 1988 carbon dioxide (CO 2 ) emissions by 20 per cent by 2005 is attained. It is concluded that over the next forty years there is substantial economic potential in Victoria for significant gains from energy efficiency in all sectors - residential, commercial, industrial and transport - and contributions from renewable energy both in those sectors and in electricity generations. 7 figs., 5 tabs

  8. Strategy for the expansion of renewable energies. An investigation of the pricing strategy of the Renewable Energy Law from the viewpoint of an evolutionary cybernetic theory of economic policy

    International Nuclear Information System (INIS)

    Schlueter, Fabian

    2015-01-01

    This publication reports on how the steadily increasing costs caused by the Renewable Energy Law (EEG) have brought the German strategy for the expansion of renewable energies under criticism. According to theories of regulatory economic policy, which state that politico-economic incentives of this kind must necessarily result in an inefficient allocation of scarce resources, this cost increase can be interpreted as a direct consequence of the price intervention. The present publication takes a critical stance on this viewpoint, developing for its purpose a new position on regulatory policy referred to as the evolutionary cybernetic theory of economic policy. It starts out from the works of F.A. von Hayek, which it then takes a significant step further however. The author argues that price interventions can be meaningful strategies of economic policy as long as they are aimed at a temporary initiation of market development towards sustainability and efficiency. Based on this model conception of a shrewd pricing strategy the publication undertakes an analysis from the perspective of regulatory policy of the German subsidisation of renewable energies. In the process it not only reveals errors in design of the EEG but also makes a proposal for an amendment that could be effective in cutting through the present price dynamics. In presenting its recommendation of a self-steering expansion policy the publication not only contributes to the further development of an evolutionary cybernetic theory of economic policy but addresses the urgent problem of how to wisely use regulatory policy to create pricing strategies which serve the expansion of renewable energies.

  9. Allocating the economic benefits of renewable energy between stakeholders on Small Island Developing States (SIDS): Arguments for a balanced approach

    Spiegel-Feld, Danielle; Rudyk, Bryce; Philippidis, George

    2016-01-01

    For many Small Island Developing States (SIDS) the cost of producing electricity from imported fossil fuels is so high and the cost of renewable energy technology has fallen so significantly that transitioning towards renewable energy is likely to produce cost savings. A recent workshop at NYU School of Law, which brought together SIDS utility representatives with a leading renewable energy developer and other stakeholders, provided strong support for this prediction. Utilities are likely to own the majority of renewable energy assets in SIDS and will therefore be the initial custodians of any cost savings renewable energy provides. This raises a key policy question: to what extent should SIDS utilities pass on these savings to consumers by lowering electricity rates? We analyze this overlooked element of energy policy and highlight undesirable consequences that complete disbursement of the savings to consumers could cause. - Highlights: • Renewables will create savings in SIDS by lowering electricity production costs. • Utilities are likely to own the bulk of renewable energy assets in SIDS. • Policymakers will need to decide how to divide savings among stakeholders. • There are compelling reasons to allow utilities to retain part of the savings. • Creditors can play a role in ensuring a prudent distribution of savings.

    On account of their low sales figures, technologies for renewable energy utilisation are still rather expensive. A more decided support for their introduction to the market could boost the development in this field. The offer submitted by Fichtner Development Engineering on 21.04.1992 served as a basis for the commission by the Federal Minister for Economic Affairs. It comprised the following individual tasks; drawing up of a list of plants to be promoted; elaboration, assessment, and selection of suitable promotion mechanisms; elaboration of cause-and-effect relationships for estimating stimulus strength; principal executive questions; increase in number of plants sold and cost of promotion. The present report deals with these points. (orig./UA) [de

    Numerous studies and market reports suggest that the solar photovoltaic markets rely heavily, if not entirely, upon governmental support policies at present. Unlike in other countries where these policies are enacted at a national level, the 50 states in the US pursue different policies in an attempt to foster the growth of renewable energy, and specifically solar photovoltaics. This paper provides an economic and financial analysis of the US federal and state level policies in states with solar-targeted policies that have markets. After putting a value on SRECs, this study further compares solar carve-outs with other incentives including the federal tax credit, net metering, and state personal tax credits. Our findings show that SREC markets can certainly be strong, with New Jersey, Delaware, and Massachusetts having the most potential. Despite their strong potential as effective renewable policies, the lack of a guaranteed minimum and the uncertainty attached are major drawbacks of SREC markets. However, the leveraging of this high value offers hope that the policies will indeed stimulate residential solar photovoltaic markets. - Highlights: ► We measure solar support incentives in eight US states with set-asides that include SREC policies. ► Compare each financial incentive using DCF, NPV, IRR, and Present Value/Watt-capacity. ► Most US SREC markets have strong potential to stimulate solar photovoltaics. ► SREC success requires price floors to alleviate uncertainty issues. ► Private financial entities can leverage SRECs to provide necessary price floors.

    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

    Highlights: • MILP model optimization identifies best structure and operation of an energy system. • Total cost of the system is minimized according to industrial stakeholders wills. • Effects of the adoption of economic support policies on the system are evaluated. • Social cost of incentives is comparted with correspondent CO 2 emission reduction. • Support schemes that promote an actual environmental benefit are highlighted. - Abstract: Economic support policies are widely adopted in European countries in order to promote a more efficient energy usage and the growth of renewable energy technologies. On one hand these schemes allow us to reduce the overall pollutant emissions and the total cost from the point of view of the energy systems, but on the other hand their social impact in terms of economic investment needs to be evaluated. The aim of this paper is to compare the social cost of the application of each incentive with the correspondent CO 2 emission reduction and overall energy saving. A Mixed Integer Linear Programming optimization procedure is used to evaluate the effect of different economic support policies on the optimal configuration and operation of a distributed energy supply system of an industrial area located in the north-east of Italy. The minimized objective function is the total annual cost for owning, operating and maintaining the whole energy system. The expectation is that a proper mix of renewable energy technologies and cogeneration systems will be included in the optimal solution, depending on the amount and nature of the supporting policies, highlighting the incentives that promote a real environmental benefit

    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)

  1. A Process for the Implementation of New Renewable Energy Systems in a Building by Considering Environmental and Economic Effect

    2015-09-01

    Full Text Available The excessive use of fossil fuels has led to global warming and air pollution. To solve these problems, interest in new renewable energy system (NRE system has increased in recent years. In particular, photovoltaic, solar thermal heating, fuel cell and ground source heating system are actively implemented for achieving the zero energy building. Since the initial investment cost of the NRE system is quite expensive, it is necessary to conduct a feasibility study from the life cycle perspective. Therefore, this study aimed to develop the process for the implementation of NRE system in a building for the optimal design. This study was conducted with four steps: (i establishing the basic information for the system installation; (ii selecting key factors affecting system performances; (iii making possible alternatives of the system installation; and (iv selecting optimal system by considering environmental and economic effect. The proposed process could enable the final decision-maker to easily and accurately determine the optimal design of the NRE systems from the economic and environmental efficiency in the early design phase. The process could also be applied to any other NRE system and could be extended to any other country in the global environment.

    We are building a multidisciplinary research program linking researchers in agriculture, business, earth science, engineering, humanities and social science. Our goal is to match renewable energy supply and reformed energy demands. The program will be focused on (i) understanding and modifying energy demand, (ii) design and implementation of diverse renewable energy networks. Geomatics technology will be used to map existing energy and waste flows on a neighbourhood, municipal, and regional level. Optimal sites and combinations of sites for solar and wind electrical generation (ridges, rooftops, valley walls) will be identified. Geomatics based site and grid analyses will identify best locations for energy production based on efficient production and connectivity to regional grids and transportation. Design of networks for utilization of waste streams of heat, water, animal and human waste for energy production will be investigated. Agriculture, cities and industry produce many waste streams that are not well utilized. Therefore, establishing a renewable energy resource mapping and planning program for electrical generation, waste heat and energy recovery, biomass collection, and biochar, biodiesel and syngas production is critical to regional energy optimization. Electrical storage and demand management are two priorities that will be investigated. Regional scale cooperatives may use electric vehicle batteries and innovations such as pump storage and concentrated solar molten salt heat storage for steam turbine electrical generation. Energy demand management is poorly explored in Canada and elsewhere - our homes and businesses operate on an unrestricted demand. Simple monitoring and energy demand-ranking software can easily reduce peaks demands and move lower ranked uses to non-peak periods, thereby reducing the grid size needed to meet peak demands. Peak demand strains the current energy grid capacity and often requires demand balancing projects and

    2016-01-01

    This paper presents a method for economic evaluation and GHGs (greenhouse gases) emissions calculation from a GCRES (grid-connected renewable energy system). An investigation is made on large-scale operations of 67 MWh/day GCRES. A comparison is performed between a GCRES and a standard grid operation focusing on environmental and economic impacts. Emissions and the Renewable energy generation fraction (RF) of total energy consumption are calculated as the main environmental indicators. Costs including NPC (net present cost), COE (cost of energy) and payback period are calculated as the economic indicators. Using the hourly mean global solar irradiance, temperature and wind speed data relative to In Salah and Adrar locations characterized by an arid and hot climate according to the Koppen–Geiger climate classification, a long-term continuous implementation of hybrid renewable energy systems are simulated using HOMER software and are discussed. As results, it is observed that a GCRES reduce 30% and 35% of GHGs emission, and 81% and 76% of COE during the operation phase respectively for In Salah and Adrar. Investments in GCRES should be considered only by planning to produce parts of the equipment locally, which leads to significantly reduce the costs and, consequently, the emissions. - Highlights: • Grid-connected renewable energy system (GCRES). • Economic evaluation and greenhouse gases (GHGs) emissions calculation. • In Salah and Adrar are taken as two examples of the famous Algerian arid land. • The climatic data are used to simulate the long-term implementation of the system.

    The author takes a look at causes of the present interest in the renewable, natural sources of energy. These are: the fuel deposits becoming exhausted, hazard to environment (especially carbon dioxide) and accessibility of these sources for under-developed countries. An interrelation is shown between these sources and the energy circulations connected with atmosphere and ocean systems. The chief ones from among them that are being used now are discussed, i.e. solar radiation, wind, water waves energy, tides, geothermal heat, and the like. Problems of conversion of the forms of these kinds of energy are also given a mention. (author)

    The European Union is divided on the issue of electricity production. While there is consensus that generation technologies need to be low on greenhouse gas emissions, the question of whether to use renewables or nuclear to meet this power demand is highly controversial. Both options still require financial support and this is not going to change in the near future. This raises the question of where public money should be invested in order to achieve greater economic efficiency: into support for renewable energies (RE) or support for nuclear power plants? This paper sets out to answer this question. The detailed model-based prospective scenario assessment performed in this study provides the basis for estimating future cost developments. After discussing the existing support schemes for renewables, the paper compares these with a nuclear model. The comparison is conducted exemplarily for the United Kingdom (UK) at a country level and for the EU 28 overall. The recent state aid case for the construction of the Hinkley Point nuclear power plant (NPP) in the UK serves as the model for the nuclear option. - Highlights: • State aids for new nuclear power is compared with incentives for renewables. • Hinkley Point C in the UK is considered as example for new nuclear power. • Comparison is conducted for the UK at a country level and for the EU 28 overall. • Analysis shows that renewable energies are more economical than nuclear power.

    Although the need to decarbonise our global economy and thus in particular the supply of energy to limit the global temperature increase is internationally undisputed the German politics in 2014 has significantly contributed less compared to previous years in order to attain this objective. The expansion of renewable energies in the electricity sector has decelerated significantly; and in the heating and mobility area no new impulses were set in relation to renewable energies. In addition, a dramatic fallen oil price makes it difficult to increase the use of renewable energy supply. Based on these deteriorated framework conditions compared to conditions of the previous years, the developments in Germany of 2014 are shown in the electricity, heat and transport sector in the field of renewable energy. For this purpose - in addition to a discussion of the current energy economic framework - for each option to use renewable energies the state and looming trends are analyzed. [German] Obwohl die Notwendigkeit zur Dekarbonisierung unserer globalen Wirtschaft und damit insbesondere der Energiebereitstellung zur Begrenzung des globalen Temperaturanstiegs international unstrittig ist, hat die deutsche Politik im Jahr 2014 im Vergleich zu den Vorjahren deutlich weniger zur Erreichung dieses Zieles beigetragen. Der Ausbau der Stromerzeugung aus erneuerbaren Energien im Stromsektor wurde deutlich verlangsamt; und im Waerme- und Mobilitaetsbereich wurden keine neuen Impulse in Bezug auf regenerative Energien gesetzt. Zusaetzlich erschwert ein drastisch gefallener Rohoelpreis die verstaerkte Nutzung des erneuerbaren Energieangebots. Ausgehend von diesen im Vergleich zu den Vorjahren verschlechterten Rahmenbedingungen werden nachfolgend die Entwicklungen in Deutschland des Jahres 2014 im Strom-, Waerme- und Transportsektor fuer den Bereich der erneuerbaren Energien aufgezeigt.

    This study aims to meet the need for scientifically robust information on the gross effects (direct and indirect) as well as on the net effects (including both conventional replacement and budget effects) of renewable energy policies in Europe. Furthermore, the future development of RES in Europe will take place against the background of a global market for RES technology. This global market and the potential share of European industries in it will play a critical role in the potentials for growth and employment. This study aims to provide a sound scientific analysis of these issues. This report is divided into four main parts, A, B, C and D. While the first three covers the introduction, the theoretical approach, the modelling steps and structure of the report, the fourth part, part D, discusses in detail the models and results of the projects. It begins with chapter D 1 which describes past RES deployment and its costs. Then follows the past macroeconomic impacts presented by gross effects on employment and value added (D 2). Thereafter, the future potential (D 3) and future deployment (D 4) of renewable energy sources (RES) are discussed. Before the presentation of the future gross and net effects, the five scenarios used in the macro-economic models (D 5) are explained in detail. Finally we depict the future gross and net impacts on employment and GDP in D 6 and D 7, respectively. The comparison between the results of the two models and our conclusion for the study follows in chapter D 8 and 9

    2006-01-01

    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

  20. Renewable, ethical? Assessing the energy justice potential of renewable electricity

    Directory of Open Access Journals (Sweden)

    2017-08-01

    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.

    Public policy and funding are basically different, but both are needed to develop the renewable energy market. Public policy creates incentives, but also obligations. The setting up of a 'repurchase rate' also called a 'feed-in tariff' or 'clean energy cash back scheme' obliges electric power companies to buy back energy of renewable origin at a fixed, guaranteed rate. The extra-cost generated, although usually low, is passed on to all customers and does not cost the State anything. Funding is characterized by its source, the manner in which it is obtained and who supplies it, whether it be banks, mutual funds, development agencies, electric power companies, local governments or the consumers themselves. Repurchasing yields regular cash flows over a given period at a lower risk and allows banks to provide funding. This is one of the reasons for its success. This solution is also very popular with political leaders because it does not weigh down public funding. Both these reasons explain why repurchasing is so appreciated in Europe and in a growing number of countries, more than seventy having adopted it in 2010. In addition, it is regularly discounted in relation to technological breakthroughs and lower costs. As is the case in Europe, the problem lies in maintaining an acceptable rate while avoiding excessive project profitability. In Europe, for instance, the number of renewable energy projects is such that consumers are starting to complain about seeing their electricity rates rise because of the famous feed-in tariff, even though the cost of renewable energies continues to drop on a regular basis. The United States and a few other countries, including China, prefer the quota system, or RPS (Renewable Portfolio Standards), which requires electric power companies to generate a minimal share of electric power by a renewable energy source. These companies consequently invest in renewable energy projects or purchase this energy from other suppliers. Like the

    Utilization of renewable energy sources and the application of environmentally sound energy technologies are essential to sustainable development and will help to secure the quality of living and the well-being of the future generations. Turkey presently has considerable renewable energy sources. The most important renewable sources are hydropower, wind, solar, geothermal, and biomass. The use of renewable energy as a topic to study energy and its forms permits a novel way to motivate students, particularly those who energy topics taking conscience with the environment. This paper presents the analysis and classification of renewable energy sources and how to find out their origin and a way to motivate students in energy topics related to renewable sources and also, the development of didactic competencies in special blended learning arrangements for educationalists, trainers and lecturers in adult education in the field of renewable energies in Turkey.

    Renewable energy consumption has been identified as a potential solution to the intermittent power supply in Ghana. Recently, a Renewable Energy Act has been passed which has a target of 10% of renewable energy component in Ghana's energy mix by 2020. Whilst effort is been made to enhance supply through feed in tariffs, education and tax reduction on renewable energy related equipment, there is the need to understand the drivers of renewable energy demand. In this study, the general unrestricted model through Autometrics is used to estimate the determinants of renewable energy demand in Ghana. The results indicate that both economic factors and non-economic affect the demand for renewable energy. In addition, the underlying energy demand trend exhibits energy using behaviour. The study recommends that economic factors such as consumer subsidies should be considered when promoting renewable energy demand.

    The specific hydrogen market determines the value of hydrogen from different sources. Each hydrogen production technology has its own distinct characteristics. For example, steam reforming of natural gas produces only hydrogen. In contrast, nuclear and solar hydrogen production facilities produce hydrogen together with oxygen as a by-product or co-product. For a user who needs both oxygen and hydrogen, the value of hydrogen from nuclear and solar plants is higher than that from a fossil plant because ''free'' oxygen is produced as a by-product. Six factors that impact the relative economics of fossil, nuclear, and solar hydrogen production to the customer are identified: oxygen by-product, avoidance of carbon dioxide emissions, hydrogen transport costs, storage costs, availability of low-cost heat, and institutional factors. These factors imply that different hydrogen production technologies will be competitive in different markets and that the first markets for nuclear and solar hydrogen will be those markets in which they have a unique competitive advantage. These secondary economic factors are described and quantified in terms of dollars per kilogram of hydrogen. (author)

    Full Text Available Afghanistan is a key country between energy surplus areas (Central Asian Republics andIran and energy deficit regions (Pakistan and India. It is in a position that can facilitate and launchregional electricity trade for the benefit of the region also derive significant gains for its own economyfrom energy imports and exports. On the other hand, Afghanistan is endowed with large renewableenergy resources (RERs, which it could exploit not only to satisfy its domestic power demand butalso to earn significant export revenue. This paper firstly explains the methodology and framework forthe power trade and then presents an optimization framework for profit maximization in the short-runtrading and cost minimization in the long-run trading. The proposed methodology is applied to a realcase between Afghanistan and Pakistan. The objective functions, parameters, variables and constraintsare described for both optimization models. System sizing, simulation and optimization are carriedout using genetic algorithm (GA technique. The results in the short-run model represent optimalityof about 2654 MW electricity export from Afghanistan to Pakistan during summer. Moreover, resultsderived from running long-run model depict that by utilizing its RERs such as solar, wind and hydro,Afghanistan can not only meet its power demand but also can export to Pakistan during its deficitperiods and gain remarkable energy profits.

    Renewable energy is now a mainstream concern among businesses and governments across the world, and could be considered a characteristic preoccupation of our time. It is interesting to note that many of the energy technologies currently being developed date back to very different eras, and even predate the industrial revolution. The fuel cell was first invented as long ago as 1838 by the Swiss--German chemist Christian Friedrich Schönbein [1], and the idea of harnessing solar power dates back to ancient Greece [2]. The enduring fascination with new means of harnessing energy is no doubt linked to man's innate delight in expending it, whether it be to satisfy the drive of curiosity, or from a hunger for entertainment, or to power automated labour-saving devices. But this must be galvanized by the sustained ability to improve device performance, unearthing original science, and asking new questions, for example regarding the durability of photovoltaic devices [3]. As in so many fields, advances in hydrogen storage technology for fuel cells have benefited significantly from nanotechnology. The idea is that the kinetics of hydrogen uptake and release may be reduced by decreasing the particle size. An understanding of how effective this may be has been hampered by limited knowledge of the way the thermodynamics are affected by atom or molecule cluster size. Detailed calculations of individual atoms in clusters are limited by computational resources as to the number of atoms that can studied, and other innovative approaches that deal with force fields derived by extrapolating the difference between the properties of clusters and bulk matter require labour-intensive modifications when extending such studies to new materials. In [4], researchers in the US use an alternative approach, considering the nanoparticle as having the same crystal structure as the bulk but relaxing the few layers of atoms near the surface.

    This thesis constitutes a study on renewable resource economics. Chapter 2 presents two types of extracting behaviour in two optimal control models, continuous and impulse control. Chapter 3 analyses stock dependent instruments and shows their advantages. Chapter 4 compares the two types of extracting behaviour and demonstrates that the impulse control generates higher gains, whereas fiscal revenues and stocks are not always higher. Chapter 5 establishes a dynamic game and shows that the scope for cooperation between heterogeneous agents is greatest for intermediary levels of heterogeneity. Chapter 6 studies forest exploitation and fiscal- and regulatory systems of the forest sector in the Democratic Republic of Congo and in France. Finally, chapter 7 presents a study on forest biodiversity and indicates the economic criteria and cutting strategies that are beneficial for biodiversity preservation. (author)

Evidence from the main policy, environmental, and economic indicators for solar and wind-power development such as feed-in tariffs, state renewable portfolio standards, public benefits fund, net metering, interconnection standards, environmental quality, electricity import ratio, per-capita energy-related carbon dioxide emissions, average electricity price, per-capita real gross domestic product, and energy intensity are discussed and evaluated in detail in order to elucidate their effectiveness in supporting the utility industry transformation. The discussion is followed by a consideration of a plausible distributed utility framework that is tailored for major DERs development that has emerged in New York called Reforming the Energy Vision. This framework provides a conceptual base with which to imagine the utility of the future as well as a practical solution to study the potential of DERs in other states. The dissertation finds this grid and market modernization initiative has considerable influence and importance beyond New York in the development of a new market economy in which customer choice and distributed utilities are prominent.

    Highlights: • A new class of the vanadium redox-flow battery (VRB) is developed. • The new class of VRB is more economic. It is simple process and easy to scale-up. • There are three levels of cell stacks and electrolytes with different qualities. • The economic analysis of the VRB system for renewable energy bases is carried out. • Related polices and suggestions based on the result are provided. - Abstract: Interest in the implement of vanadium redox-flow battery (VRB) for energy storage is growing, which is widely applicable to large-scale renewable energy (e.g. wind energy and solar photo-voltaic), developing distributed generation, lowering the imbalance and increasing the usage of electricity. However, a comprehensive economic analysis of the VRB for energy storage is obscured for various commercial applications, yet it is fundamental for implementation of the VRB in commercial electricity markets. In this study, based on a new class of the VRB that was developed by our team, a comprehensive economic analysis of the VRB for large-scale energy storage is carried out. The results illustrate the economy of the VRB applications for three typical energy systems: (1) The VRB storage system instead of the normal lead-acid battery to be the uninterrupted power supply (UPS) battery for office buildings and hospitals; (2) Application of vanadium battery in household distributed photo-voltaic power generation systems; (3) The wind power and solar power stations equipped with the VRB storage systems. The economic perspectives and cost-benefit analysis of the VRB storage systems may underpin optimisation for maximum profitability. In this case, two findings are concluded. First, with the fixed capacity power or fixed discharging time, the greater profit ratio will be generated from the longer time or the larger capacity power. Second, when the profit ratio, discharging time and capacity power are all variables, it is necessary to find out the best optimisation

    This comprehensive lecture given by Prof. Dr. Gunter Schaumann in Bad Duerkheim, Germany, discusses the use of geothermal energy in relationship to other forms of renewable energy sources and conventional energy technologies used to provide heat, power and motive force. The characteristics of geothermal energy from various sources and examples of its possible use are discussed. In particular, the paper deals with deep geothermal energy, which can provide heating energy for district heating schemes, if necessary with the help of heat pumps. The prospects of such a use of geothermal energy in the next 50 years in various suitable regions in Germany is discussed and the associated prerequisites are listed. The present situation concerning the use of geothermal energy in Germany is examined. An example of a geothermal heating power station that also features a gas-fired combined heat and power installation, a heat pump and a peak-load boiler is given. Also, the generation of electrical power using the Organic Rankine Cycle is discussed. The factors influencing the economic viability of geothermal power stations are discussed in detail and the resulting energy prices are compared with conventional plants. The paper gives details of the calculation of investment and energy costs for heat and power generation and presents figures based on exemplary installations.

    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

    The aim of this work is to analyze the political, regulatory, economic and technical issues that have determined the use of primary energies for power generation in Mexico from 1965 to 2008, and its perspectives for the next 10 years, in particular the prospects of using renewable energies. In the 60's, hydro was the preferred source of energy to produce electricity for economical and technical reasons. Under the 'oil boom' in the 70s, transition to hydrocarbons resources (fuel oil) was progressive. As a result of implementing environmental policies, electricity has mainly been generated with natural gas since the early 2000.

    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

    2011-01-01

    Full Text Available An equilibrium economic model for policy evaluation related to electricity generation in U.S has been developed; the model takes into account the non-renewable and renewable energy sources, demand and supply factors and environmental constraints. The non-renewable energy sources include three types of fossil fuels: coal, natural gas and petroleum, and renewable energy sources include nuclear, hydraulic, wind, solar photovoltaic, biomass wood, biomass waste and geothermal. Energy demand sectors include households, industrial manufacturing and non-manufacturing commercial enterprises. Energy supply takes into account the electricity delivered to the consumer by the utility companies at a certain price which maybe different for retail and wholesale customers. Environmental risks primarily take into account the CO2 generation from fossil fuels. The model takes into account the employment in various sectors and labor supply and demand. Detailed electricity supply and demand data, electricity cost data, employment data in various sectors and CO2 generation data are collected for a period of nineteen years from 1990 to 2009 in U.S. The model is employed for policy analysis experiments if a switch is made in sources of electricity generation, namely from fossil fuels to renewable energy sources. As an example, we consider a switch of 10% of electricity generation from coal to 5% from wind, 3% from solar photovoltaic, 1% from biomass wood and 1% from biomass waste. The model is also applied to a switch from 10% coal to 10% from clean coal technologies. It should be noted that the cost of electricity generation from different sources is different and is taken into account. The consequences of this switch on supply and demand, employment, wages, and emissions are obtained from the economic model under three scenarios: (1 energy prices are fully regulated, (2 energy prices are fully adjusted with electricity supply fixed, and (3 energy prices and

    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

    Recently a great number of empirical research studies have been conducted on the relationship between certain indicators of environmental degradation and income. The EKC (Environmental Kuznets Curve) hypothesis has been tested for various types of environmental degradation. The EKC hypothesis states that the relationship between environmental degradation and income per capita takes the form of an inverted U shape. In this paper the EKC hypothesis was investigated with regards to the relationship between carbon emissions, income and energy consumption in 16 EU (European Union) countries. We conducted panel data analysis for the period of 1990–2008 by fixing the multicollinearity problem between the explanatory variables using their centered values. The main contribution of this paper is that the EKC hypothesis has been investigated by separating final energy consumption into renewable and fossil fuel energy consumption. Unfortunately, the inverted U-shape relationship (EKC) does not hold for carbon emissions in the 16 EU countries. The other important finding is that renewable energy consumption contributes around 1/2 less per unit of energy consumed than fossil energy consumption in terms of GHG (greenhouse gas) emissions in EU countries. This implies that a shift in energy consumption mix towards alternative renewable energy technologies might decrease the GHG emissions. - Highlights: • We investigate the EKC (Environmental Kuznets Curve) hypothesis for 16 EU (European Union) countries. • We fix the multicollinearity problem between explanatory variables. • We found no evidence to support the EKC hypothesis in EU between 1990 and 2008 periods. • Renewable energy contributes less to GHGs (greenhouse gases) around ½ that of a unit of fossil energy

    Ghadimian, Vachik

    The renewable energy sector is evolving, and today, renewable energy has become a viable alternative for many facilities. Because this sector is in its infancy stage, lack of experience has resulted in failing solar projects. This project involves the design and implementation of a functioning web application that streamlines and automates the planning, risk assessment and financing of a solar development project. The three key stakeholders, the host facility, solar installer and financier are seamlessly integrated into a single marketplace. By designing a project development workflow, projects are vetted early on and terminated if deemed infeasible, saving time and resources. By risk assessing the project using the proposed scoring model, one can inherit more confident investors. The project scoring model also serves as a debt rating system, where investors can measure the risk/rewards. The platform will also serve as a communication medium between the three stakeholders. Besides storing documents like engineering drawings, permits, etc., the platform auto-generates all necessary transactional documents, legal documents and agreements among the three stakeholders.

    The energy sector in Lebanon plays an important role in the overall development of the country, especially that it suffers from many serious problems. The fact that Lebanon is among the few countries that are not endowed with fossil fuels in the Middle East made this sector cause one third of the national debt in Lebanon. Despite the large government investments in the power sector, demand still exceeds supply and Lebanon frequently goes through black out in peak demand times or has to resort to importing electricity from Syria. The Energy production sector has dramatic environmental and economical impacts in the form of emitted gasses and environment sabotage, accordingly, it is imperative that renewable energy (RE) be looked at as an alternative energy source. Officials at the Ministry of Energy and Water (MEW) and Lebanese Electricity (EDL) have repeatedly expressed their support to renewable energy utilization. So far, only very few renewable energy applications can be observed over the country. Major efforts are still needed to overcome this situation and promote the use of renewable energy. These efforts are the shared responsibility of the government, EDL, NGO's and educational and research centers. Additionally, some efforts are being made by some international organizations such as UNDP, ESCWA, EC and other donor agencies operating in Lebanon. This work reviews the status of Energy in Lebanon, the installed RE projects, and the potential projects. It also reviews the stakeholders in the field of RE in Lebanon Conclusion In considering the best R.E. alternative, it is important to consider all potential R.E. sources, their costs, market availability, suitability for the selected location, significance of the energy produced and return on investment. Several RE resources in Lebanon have been investigated; Tides and waves energy is limited and not suitable two tentative sites for geothermal energy are available but not used.

    Since Taiwan imports more than 99% of energy supply from foreign countries, energy security has always been the first priority for government to formulate energy policy. The development of renewable energy not only contributes to the independence of energy supply, but also achieves benefits of economic development and environmental protection. Based upon information available to public, the present paper reassesses reserves of various renewable energies in Taiwan. The assessment includes seven kinds of renewable energies, namely, solar energy, wind power, biomass energy, wave energy, tidal energy, geothermal energy and hydropower, which are all commercialized and matured in terms of current technologies. Other renewable energies, which have not proven as matured as the aforementioned ones, are only assessed preliminarily in this paper, such as second generation of biomass, deep geothermal energy, the Kuroshio power generation and ocean thermal energy conversion. According to the estimation of this paper, the reserve of wind energy, up to 29.9 kWh/d/p (i.e., kWh per day per person), is the largest one among seven kinds of renewable energies in Taiwan, followed by 24.27 kWh/d/p of solar energy, 4.55 kWh/d/p of biomass, 4.58 kWh/d/p of ocean energy, 0.67 kWh/d/p of geothermal energy and 16.79 kWh/d/p of hydropower. If regarding biomass as a primary energy, and assuming 40% being the average efficiency to convert primary energy into electricity, the total power of the seven kinds of renewable energy reserves is about 78.03 kWh/d/p, which is equal to 2.75 times of 28.35 kWh/d/p of national power generation in 2008. If the reserves of 54.93 kWh/d/p estimated from other four kinds of renewable energies that have not technically matured yet are also taken into account, it will result that the reserves of renewable energy in Taiwan can be quite abundant. Although the results of the assessment point out that Taiwan has abundant renewable energy resources, the four inherent

Figure 2 compares the EIA's natural gas wellhead price forecast from each year's Annual Energy Outlook (AEO) going back to 1985 against the average US wellhead price that actually transpired. As shown, our forecasting abilities have proven rather dismal over time, as over-forecasts made in the late 1980's eventually yielded to under-forecasts that have persisted to this day. This historical experience demonstrates that little weight should be placed on any one forecast of future natural gas prices, and that a broad range of future price conditions ought to be considered in planning and investment decisions. Against this backdrop of high, volatile, and unpredictable natural gas prices, increasing the market penetration of renewable generation such as wind, solar, and geothermal power may provide economic benefits to ratepayers by displacing gas-fired generation. These benefits may manifest themselves in several ways. First, the displacement of natural gas-fired generation by increased renewable generation reduces ratepayer exposure to natural gas price risk--i.e., the risk that future gas prices (and by extension future electricity prices) may end up markedly different than expected. Second, this displacement reduces demand for natural gas among gas-fired generators, which, all else equal, will put downward pressure on natural gas prices. Lower natural gas prices in turn benefit both electric ratepayers and other end-users of natural gas. Using analytic approaches that build upon, yet differ from, the past work of others, including Awerbuch (1993, 1994, 2003), Kahn and Stoft (1993), and Humphreys and McClain (1998), this chapter explores each of these two potential 'hedging' benefits of renewable electricity. Though we do not seek to judge whether these two specific benefits outweigh any incremental

    Energy efficiency in Poland is driven primarily by price signals. Due to Poland's recent international obligations towards addressing climate change, various sustainable energy policies have been established to foster energy efficiency as well as to define the conditions of conducting economic activities in the energy sector. This paper presented the results of an empirical ex-ante analysis which examined the effects of various potential energy policies in the Polish bioenergy sector. An applied general equilibrium model was used in which producers responded to changes in market prices of different energy products by adjusting their output and input levels. The model consisted of 3 major sections, namely production, consumption, and equilibrium conditions. The model used a set of simultaneous linear and non-linear equations to define the behaviour of economic agents. Each solution provided a full set of economic indicators, including household incomes, prices, supply and demand quantities for factors and commodities, and welfare indicators. Consumers in the model responded to changes in energy product prices with a reduced demand of certain goods and services, as well as by increasing demand for other services. Results of the simulation showed that a uniform subsidy led to the same increase of renewable energy supply as an equivalent uniform fossil energy tax. Results also indicated that reductions in the output of fossil fuel energy sectors below the reference case did not impact all fossil energy sectors equally. A subsidy was found to lower the average cost of production, while taxation was found to increase the average cost of production. It was concluded that the bioenergy sector will benefit more from an indirect tax reduction than from a removal of fossil energy sector subsidies. 25 refs., 3 tabs., 3 figs

    A dynamic macroeconomic model of the Wisconsin economy is used to estimate the economic impacts of displacing a portion of future investment in fossil fuel power plants (coal and natural gas) with renewable energy resources (biomass, wind, solar and hydro). The results show that renewable energy investments produce over three times more jobs, income and economic activity than the same amount of electricity generated from coal and natural gas power plants. Between 1995 and 2020, a 75% increase in renewable energy use generates approximately 65,000 more job-years of employment, $1.6 billion in higher disposable income and a $3.1 billion increase in gross regional product than conventional power plant investments. This includes the effects of a 0.3% average annual increase in electricity prices from renewable energy investments

    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.

    Renewable energies are essential contributors to the energy supply portfolio as they contribute to world energy supply security, reducing dependency on fossil fuel resources, and provide opportunities for mitigating greenhouse gases. Differences in definition and lack of adequate data complicated the discussion between participants on these key issues. The International Energy Agency believes that this fact sheet can be of use to all to facilitate the debate on the past, current and future place and role of renewables in total energy supply. Our goal is to present as objectively as possible the main elements of the current renewables energy situation. The definitions and coverage of national statistics vary between countries and organisations. In this fact sheet, the renewables definition includes combustible renewables and waste (CRW), hydro, geothermal, solar, wind, tide and wave energy.

    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

  7. Modeling renewable energy company risk

    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.

    Several renewable energy options are discussed, namely solar energy, passive solar systems, photovoltaics, wind energy and biomass. Although technical feasibility has been shown for various systems, there has been slow growth in their implementation. Some aspects of this slow growth are in the domains of economic viability, long term reliability, the training of operators and installers, public perception and education and govenmental attitudes. It is estimated that the increased use of renewable energy depends on several factors which include government policies, funding, energy conservation, pricing policies, reliable commercial products, public education and adequate training. 11 refs

    Phytoremediation could be a sustainable remediation alternative for conventional remediation technologies. However, its implementation on a commercial scale remains disappointing. To emphasize its sustainability, this paper examines whether and how the potential economic benefit of CO 2 abatement for different crops used for phytoremediation or sustainable land management purposes could promote phytotechnologies. Our analysis is based on a case study in the Campine region, where agricultural soils are contaminated with mainly cadmium. We use Life Cycle Analysis to show for the most relevant crops (willow (Salix spp), energy maize (Zea mays), and rapeseed (Brassica napus)), that phytoremediation, used for renewable energy production, could abate CO 2 . Converting this in economic numbers through the Marginal Abatement Cost of CO 2 (€ 20 ton −1 ) we can integrate this in the economic analysis to compare phytoremediation crops among each other, and phytoremediation with conventional technologies. The external benefit of CO 2 abatement when using phytoremediation crops for land management ranges between € 55 and € 501 per hectare. The purpose of these calculations is not to calculate a subsidy for phytoremediation. There is no reason why one would prefer phytoremediation crops for renewable energy production over “normal” biomass. Moreover, subsidies for renewable energy already exist. Therefore, we should not integrate these numbers in the economic analysis again. However, these numbers could contribute to making explicit the competitive advantage of phytoremediation compared to conventional remediation technologies, but also add to a more sustainably funded decision on which crop should be grown on contaminated land. -- Highlights: ► We add CO 2 abatement for each remediation crop to the private economic analysis. ► This values the advantage of phytoremediation compared to conventional remediation. ► This leads to a crop choice that considers an

    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.

    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)

    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.)

    Like many countries in Africa, Senegal is facing economical decline, energy crisis and serious desertification problem in rural areas. These issues could be removed if renewable energy is used as a primary source of energy in rural areas. What is required is a strategy to implement renewable energy technologies at large scale. The government and many non-governmental organisations (NGOs) have tried to comprehend and have strived to address the problem of energy. This paper present a review of activities in the field of renewable energy applications in Senegal, which goes back to the mid 1970s and will discuss the socio-economic benefits that the country has derived from these environmentally sound and appropriate sources of energy. The development and trial of systems were mostly funded so far by donor agencies in collaboration with government and NGOs. Among the applications being supported are solar lighting, water pumping and small power plants. Recent efforts have been aimed at restructuring the programmes and giving them a market orientation. Future trends, some suggestion and recommendations for successful dissemination of renewable energy sources are also drawn. The present situation is seen to be much more promising and favourable for renewable energy. (Author)

  15. Economics of intermittent renewable energy sources: four essays on large-scale integration into European power systems

    2014-01-01

    This thesis centres on issues of economic efficiency originating from the large-scale development of intermittent renewable energy sources (RES) in Europe. The flexible resources that are necessary to cope with their specificities (variability, low-predictability, site specificity) are already known, but adequate signals are required to foster efficient operation and investment in these resources. A first question is to what extent intermittent RES can remain out of the market at times when they are the main driver of investment and operation in power systems. A second question is whether the current market design is adapted to their specificities. These two questions are tackled in four distinct contributions.The first chapter is a critical literature review. This analysis introduces and confronts two (often implicit) paradigms for RES integration. It then identifies and discusses a set of evolutions required to develop a market design adapted to the large-scale development of RES, such as new definitions of the products exchanged and reorganisation of the sequence of electricity markets.In the second chapter, an analytical model is used to assess the potential of intra-day markets as a flexibility provider to intermittent RES with low production predictability. This study highlights and demonstrates how the potential of intra-day markets is heavily dependent on the evolution of the forecast errors.The third chapter focuses on the benefits of curtailing the production by intermittent RES, as a tool to smooth out their variability and reduce overall generation costs. Another analytical model is employed to anatomise the relationship between these benefits and a set of pivotal parameters. Special attention is also paid to the allocation of these benefits between the different stakeholders.In the fourth chapter, a numerical simulation is used to evaluate the ability of the European transmission system operators to tackle the investment wave required in order to

    To promote the development and application of renewable energy, under the planning and execution of Bureau of Energy of Ministry of Economical Affairs (BOEMOEA), Taiwan has implemented many measures for subsidizing the installation of RE apparatus since 2000. Besides subsidizing the installing expenses, Taiwanese government also provides incentive measures of finance/tax, such as investment deduction and accelerating depreciation. The successive growth of the amount of installing cases has apparently constructed the base of promotion and application of renewable energy; on the other hand, many barriers to be overcome were continuously discovered during the executing processes. To effectively remove these promoting barriers, the Energy Commission (the pre-BOE) issued 'Renewable Energy Development Plan' through the endorsement of Executive Yuan in January 2002. The purpose of this plan is to establish an inter-ministerial coordinating mechanism of a higher administrative level, which may focus all resources to be functioned as a working team. In the meantime, to further establish a systematically promoting mechanism, the Bureau of Energy then pushes the legislation of 'Renewable Energy Development Bill'. According to the drafted plan of this law, the power capacity of renewable energies will be 12% share of the national power installation capacity by 2020. Furthermore, in the Nuclear-free Homeland National Conference held in June 2003, government planned that the power capacity of renewable energy must reach 10% of the total power capacity in the nation by 2010. However, the share of the power capacity of renewable energy to the national power installation capacity is only 6.17%, currently, so there is still a lot of growing space for the development of renewable energy in Taiwan.

    This study aims to propose a new optimization-based approach for design and analysis of the stand-alone hybrid energy supply system using renewable energy sources (RES). In the energy supply system, we include multiple energy production technologies such as Photovoltaics (PV), Wind turbine, and fossil-fuel-based AC generator along with different types of energy storage and conversion technologies such as battery and inverter. We then select six different regions of Korea to represent various characteristics of different RES potentials and demand profiles. We finally designed and analyzed the optimal RES stand-alone energy supply system in the selected regions using multiobjective optimization (MOOP) technique, which includes two objective functions: the minimum cost and the minimum CO{sub 2} emission. In addition, we discussed the feasibility and expecting benefits of the systems by comparing to conventional systems of Korea. As a result, the region of the highest RES potential showed the possibility to remarkably reduce CO{sub 2} emissions compared to the conventional system. Besides, the levelized cost of electricity (LCOE) of the RES-based energy system is identified to be slightly higher than conventional energy system: 0.35 and 0.46 $/kWh, respectively. However, the total life-cycle emission of CO{sub 2} (LCECO{sub 2}) can be reduced up to 470 gCO{sub 2}/kWh from 490 gCO{sub 2}/kWh of the conventional systems.

    This publication first proposes a presentation of the SER (Syndicat des Energies Renouvelables, Syndicate of Renewable Energies), a professional body: missions, scope of action, members. It outlines its commitment in the French policy for energy transition as a major actor of the sector of renewable energies. It addresses the legal and regulatory framework by indicating evolutions introduced by the French law for energy transition and for a green growth for the different renewable energies (hydroelectricity, wind energy, solar photovoltaic, geothermal, biofuels and bio-energies, biogas), by the new regimes of authorisations for onshore wind energy, methanization and hydroelectricity, and by the law for growth, activity and equality of economic opportunities. It proposes brief presentations of transverse actions (agreements, meetings, partnership in exhibitions, commitment in the COP21), and of actions regarding power grids, overseas territories, or the building sector. Some highlights related bio-energy sectors, geothermal energy, onshore wind energy, renewable marine energies and offshore wind energy, solar photovoltaic energy, hydroelectricity, or solar thermodynamic energy are mentioned. These highlights may concern legal, organisational, political or financial frameworks. Actions in the field of communication are indicated, and projects for 2016 are briefly indicated

    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.

    Fossil fuel reserves are diminishing rapidly across the world. Greenhouse gas emissions, climatic changes and global warming have a direct impact on the environment. A secure and accessible supply of energy is very crucial for the sustainability of modern societies. There is an urgent need for a quicker switch over of energy systems from conventional to renewable that are sustainable and can meet the present and projected world energy demand. Renewable energy has a large potential to become the fuel of the future. The present study is aimed to explore such potential and achievements in India. India is expected to have high growth rate in energy demand over the coming years due to its huge population and rapid economic development. The renewable energy prospects/spectrums of India have been highlighted. (author)

  9. Renewable Resources, Capital Accumulation, and Economic Growth

    Full Text Available This paper proposes a dynamic economic model with physical capital and renewable resources. Different from most of the neoclassical growth models with renewable resources which are based on microeconomic foundation and neglect physical capital accumulation, this study proposes a growth model with dynamics of renewable resources and physical capital accumulation. The model is a synthesis of the neoclassical growth theory and the traditional dynamic models of renewable resources with an alternative approach to household behavior. The model describes a dynamic interdependence among physical accumulation, resource change, and division of labor under perfect competition. Because of its refined economic structure, our study enables some interactions among economic variables which are not found in the existing literature on economic growth with renewable resources. We simulate the model to demonstrate the existence of equilibrium points and motion of the dynamic system. Our comparative dynamic analysis shows, for instance, that a rise in the propensity to consume the renewable resource increases the interest rate and reduces the national and production sector’s capital stocks, wage rate and level of the consumption good. Moreover, it initially reduces and then increases the capital stocks of the resource sector and the consumption and price of the renewable resource. The stock of the renewable resource is initially increased and then reduced. Finally, labor is redistributed from the production to the resource sector.

    The world has to face increasing energy needs while it is today dependent of fossil fuels at 80%. Getting out of the fossil fuels dependence model requires an important effort to promote the energy saving and the carbon-free energies as well, and in particular the renewable energy sources. Taking all this information into account, the authors evaluate the global share that renewable energies could represent in the energy mix, in France and in the entire world. This share represents today only 10% of the energy consumed, but will it remain marginal or will it become important and eventually prominent? (J.S.)

    1998-01-01

    The share of renewable energy sources (RES) in the world energy balance is estimated from 1-2 to 10% of the total primary energy sources consumption. In EU since 1990 until now the power energy production from these sources is growing continuously by over 3% annually. The features of the updated Environmental Strategy for Bulgaria (ESB) elaborated with the World Bank in 1994 are: increasing the energy efficiency; utilising RES; granting preference to the regional energy concept and establishing regional energy centres based on the EU experience. In ESB the basic priorities are linked with disease factors - pollutants as lead in the air and soils (from leaded petrol, resp. from metallurgical enterprises), dust particles in the air (from household heating, industry and thermo-electric power stations) and sulfur dioxide and other gases (also from energy sector and industry). There is consistent policy for harmonization of the Bulgarian standards with those of the WHO. Among the implemented projects preference is granting to ones concerning new energy saving technologies and RES. Bulgaria got an environmental protection law harmonized with the international legislation and adapted to the economic situation inflicted by the market economy transition. The development of RES needs high investment cost and has low efficiency factor compared to the classical methods of energy production. Implementation of Environmental Action Programme (EAP) in Bulgaria with an international co-operation includes: solid wastes management; water sources management; water pollution problems; soil degradation; transport and environment; nuclear safety and nuclear waste problems and full value utilization of the RES. The Ministry of Environment and local Authorities have to develop their policies and implementing them by a range of activities to identify pollution control strategies, to identify areas where the greatest environmental benefits can be achieved at least cost and to incorporate the

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.

  16. Is renewable energy effective in promoting growth?

    International Nuclear Information System (INIS)

    Marques, António Cardoso; Fuinhas, José Alberto

    2012-01-01

    This paper applies panel data techniques to analyze the role of the various energy sources in economic growth, for a set of 24 European countries (1990–2007), controlling for energy consumption and energy dependency. The results suggest that the negative effect of the use of renewables supplants the positive effect of creating income by exploiting a natural resource locally, and thus growth does not appear to improve with the change towards renewables. The high costs of promoting renewables are probably being placed excessively upon the economy, namely by increasing the costs of electricity tariffs, thus inducing a deceleration in economic activity. Fossil fuels lead to dissimilar effects on growth while natural gas does not appear to be relevant in explaining growth. Coal hampers the capacity for growth, whereas the use of oil stimulates that growth. This is in line with productive structures that are deeply grounded in fossil fuels, particularly oil. - Highlights: ► We empirically test the distinct effects of decomposing energy by source on growth. ► We focus on 24 European Countries (1990–1907) by applying a panel data approach. ► Fossil fuels lead to dissimilar effects on growth. Coal hampers and oil stimulates it. ► Economic growth does not appear to improve with the paradigm change to renewable. ► High costs of promotion of renewables are being placed excessively upon the economy.

    On January 23, 2008, the European Commission presented proposals in the form of a directive in an effort to give more specific shape to the objective adopted in the spring, i.e. to increase to 20% by 2020 the share of renewable energies in energy consumption in the Community. The proposal was to include legally binding goals for the overall share of renewable energy sources and the share of biofuels in the transport sector. The proposed directive on 'promoting the use of energy from renewable sources' calls upon each member state to ensure that its share of energy from renewable sources in the total energy consumption in 2020 at least corresponds to the target mentioned in Annex I Part A. In addition to the targets, the EU Commission charted a tentative course towards a minimum increase in the share of renewable energies in the period between 2011 and 2020. Finally, the member states are obliged to adopt national action plans. Unfortunately, the EU is missing an important target in its proposed directive: It should establish a framework for harmonized conditions promoting the use of renewable energies. One aspect to be welcomed is the introduction of a system of certificates of origin. It represents the entry, in principle, into a trading system with certificates of origin. The Green Package incorporates a wealth of new approaches. They will have to be tested and, if necessary, supplemented. Something else is evident, however: The directive established the foundations of a vast number of new regulations and red tape. (orig.)

    About 3 quarter of the Italian electric power comes from fossil fuel power plants. The rest is generated from hydropower, few comes from biomass and wind energy and a very few from geothermal energy (2% of the national production). However, the situation is changing and geothermal energy, with only 5 TWh, makes Italy the European leader in this domain and the world number 4 behind USA, Philippines and Mexico. The renewable sources represent 18.5% of the total Italian energy production. During the last five years, the renewable energy sources have developed rapidly: +80% per year for the wind energy, +32% per year for biomass and about +3% per year for geothermal energy. Moreover, the Italian government is implementing incentives for the development of renewable energy sources. This article gives an overview of the situation. (J.S.)

    The European renewable energy industry has the potential to be a world leader. This has been achieved within the European region for specific technologies, through a set of policy activities at a national and regional level, driven primarily by employment, energy self-sufficiency and industrial competitiveness. Using the experience gained in recent years, European industry has the opportunity to continue to expand its horizons on a worldwide level. Through the use of the SAFIRE rational energy model, an assessment has been made of the future penetration of renewable energy within Europe and the effects on these socio-economic factors. In conjunction with these outputs, assessments of the worldwide markets for wind, photovoltaics, solar thermal plant and biomass have been assessed. A case study of the Danish wind industry is used as a prime example of a success story from which the learning opportunities are replicated to other industries, so that the European renewable energy industry can achieve its potential.

    TNB has a big role to play in Malaysia 's pursuit for modernization and socioeconomic progress. The most important task is to fulfill the nation's electricity demand in the most reliable manner and at the lowest cost possible with minimal of environmental impacts. TNB is committed to the development of renewable energy in this country. In fact, hydropower, which is a form of renewable energy, contributed significant proportion of the generating capacity in TNB. Research works on other forms of renewable energy like solar, wind, and biomass are actively being pursued by Tenaga Nasional Research and Development Sdn Bhd. As solar and wind energy systems are by nature emission-free, they provide a ready solution to the current air pollution and global warming problems. With the depletion of conventional non-renewable energy resources like oil, gas, and coal, the emergence of renewable energy as a reliable, alternative source of fuel would enhance security of energy supply in the long run. Because renewable energy is sourced locally, the country will benefit economically due to the cut on imported fuel and hence foreign exchange losses. For the policy makers, the most challenging task ahead is how to re-strategised the present policy on fuels in order to accommodate the contributions from other forms of renewable energy (other than hydro) without compromising on system reliability and cost to the customers. On DSM and Energy Efficiency programs pursued by TNB, the objective in is to discourage wasteful and expensive patterns of energy consumption. In that way, new electricity demand need not necessarily be met by new investment on new power stations. (Author)

    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)

    Full Text Available In order to encourage the eco-friendly technologies in transportation sector, the reliance on fuel need to be reduced and the use of renewable energy (RE technology as energy source are widely explored by researchers. Thus, this study focus on the feasibility of developing grid-connected renewable energy electric boat charging station for the fishermen in Terengganu using simulation-based method by HOMER software. Five year solar radiation and wind speed data were collected at Universiti Sultan Zainal Abidin (UNISZA weather station. For load profile, the information about fishing activities and the amount of subsidy spent by the government were obtained from the interview session with the fishermen and validated with Lembaga Kemajuan Ikan Malaysia (LKIM. The results acquired are compared between grid-only and grid-connected RE systems in term of net present cost (NPC, operational cost and payback period. A sensitivity analysis is done to find the minimal Feed-in Tariff (FiT rate that can be implemented in order to encourage the use of RE system in this sector. Then, the relationship between FiT and NPC, payback period and emission of pollutants are analyzed. At current FiT rates RM 0.813/kWh, hybrid grid-PV system manages to achieve its optimal in generating high income from selling the power to the grid with convincing amount of electricity production and short payback period. It is concluded at minimum RM 0.56/kWh of FiT, the grid-connected RE system is possible to be developed because its performance shows better outcome compared to the grid-only system.

  11. Combining Renewable Energy With Coal

    2013-09-01

    There are various possibilities for incorporating biomass into coal-fuelled processes and a number of these are already being deployed commercially. Others are the focus of ongoing research and development. Biomass materials can vary widely, although the present report concentrates mainly on the use of woody biomass in the form of forest residues. Potentially, large amounts are available in some parts of the world. However, not all forested regions are very productive, and the degree of commercial exploitation varies considerably between individual countries. The level of wastage associated with timber production and associated downstream processing is frequently high and considerable quantities of potentially useful materials are often discarded. Overall, forest residues are a largely underexploited resource. Combining the use of biomass with coal can be beneficial, particularly from an environmental standpoint, although any such process may have its limitations or drawbacks. Each coal type and biomass feedstock has different characteristics although by combining the two, it may be possible to capitalise on the advantages of each, and minimise their individual disadvantages. An effective way is via cogasification, and useful operating experience has been achieved in a number of large-scale coal-fuelled gasification and IGCC plants. Cogasification can be the starting point for producing a range of products that include synthetic natural gas, chemicals, fertilisers and liquid transport fuels. It also has the potential to form the basis of systems that combine coal and biomass use with other renewable energy technologies to create clean, efficient energy-production systems. Thus, various hybrid energy concepts, some based on coal/biomass cogasification, have been proposed or are in the process of being developed or trialled. Some propose to add yet another element of renewable energy to the system, generally by incorporating electricity generated by intermittent

    Although the vast majority of renewable energies projects are established by commercial developers, some of them are financed by ''ordinary citizens'' pooling together through different schemes. This is particularly frequent in Denmark and Germany, possibly a key reason for the continuous and so successful growth of various renewable energies sources in these countries. This guideline aims to define the term of local investment and provides examples of development and recommendations. (A.L.B.)

    Full Text Available The Energy-CSOP facilitates broad equity participation of citizens without assets or savings in a regulated public energy utility. As the CSOP is designed for regulated markets with guaranteed prices, regulated market access and long-term relationships between producer and consumer, the energy market is predestined. A CSOP trust can be set up for a renewable energy plant (e.g., a biogas reactor, a solar panel, a windmill or a geothermic drill. European states have set an ambitious target to reach 20% share of energy from renewable sources by 2020. Germany as Europe’s green energy leader could become a pioneer in CSOP implementation. Small communities in Europe would benefit from the increased share of renewable energy resources.

    The main objectives of this thesis are: to investigate technological change and cost reduction for a number of renewable electricity technologies by means of the experience curve approach; to address related methodological issues in the experience curve approach, and, based on these insights; and to analyze the implications for achieving the Dutch renewable electricity targets for the year 2020 within a European context. In order to meet these objectives, a number of research questions have been formulated: What are the most promising renewable electricity technologies for the Netherlands until 2020 under different technological, economic and environmental conditions?; To what extent is the current use of the experience curve approach to investigate renewable energy technology development sound, what are differences in the utilization of this approach and what are possible pitfalls?; How can the experience curve approach be used to describe the potential development of partially new energy technologies, such as offshore wind energy? Is it possible to describe biomass fuel supply chains with experience curves? What are the possibilities and limits of the experience curve approach when describing non-modular technologies such as large (biomass) energy plants?; What are the main learning mechanisms behind the cost reduction of the investigated technologies?; and How can differences in the technological progress of renewable electricity options influence the market diffusion of renewable electricity technologies, and what implications can varying technological development and policy have on the implementation of renewable electricity technologies in the Netherlands? The development of different renewable energy technologies is investigated by means of some case studies. The possible effects of varying technological development in combination with different policy backgrounds are illustrated for the Netherlands. The thesis focuses mainly on the development of investment

    Energy saving and emission reduction have become targets for modern society due to the potential energy crisis and the threat of climate change. A distributed hybrid renewable energy system (HRES) consists of photovoltaic (PV) arrays, a wood-syngas combined heat and power generator (CHP) and back-up batteries is designed to power a typical semi-detached rural house in China which aims to meet the energy demand of a house and to reduce greenhouse gas emissions from the use of fossil fuels. Based on the annual load information of the house and the local meteorological data including solar radiation, air temperature, etc., a system model is set up using HOMER software and is used to simulate all practical configurations to carry out technical and economic evaluations. The performance of the whole HRES system and each component under different configurations are evaluated. The optimized configuration of the system is found

    The enactment of the Law Giving Priority to Renewable Energies (EEG) in 2000 laid the cornerstone for the transformation of the German electricity supply. Since then the proportion of renewable energy in electricity production has grown dramatically, confronting the German network infrastructure, which was initially designed for a centralised supply system, with new problems and challenges. In order to achieve optimal coordination between volatile energy infeeds, electricity storage plants and consumers it is necessary to bring all components involved together in a smart grid. A small-scale grid of this description is currently being operated and investigated on the EUREF Campus in Berlin Schoeneberg. The task of achieving optimal allocation of energy flows and getting the micro smart grid to run accordingly, i.e. at a profit, poses new challenges to all involved. To be able to determine the economic efficiency of smart grids a calculation model was developed which simulates the operation of production and storage plants and takes the behaviour of real consumers into account. The model rates the profitability of investments made in terms of their capital value. In its current version the model still disregards the legal regulations for the remuneration of electricity produced from a mix of renewable resources. These cannot be considered as physically separate in a smart grid. In the present study a module based on EEG provisions was developed which calculates remuneration rates as a function of production and demand at a given moment. This is one of several factors which influence the economic efficiency of smart grids. The study undertakes to identify these factors and describe their influence on the profitability of the total investment.

    A prominent feature of renewable energy utilisation is the magnitude of renewable energy that is physically available worldwide. The present paper attempts an economic valuation of development strategies for renewable energy sources (RES) on the basis of the past development of RES markets. It comes to the conclusion that if current energy prices remain largely unchanged, it will be necessary to promote RES technologies differentially according to the technique and type of energy employed or to provide start-up funding. The more probable a long-term increase in energy prices becomes, the greater will be the proportion of successfully promoted technologies. Energy taxes on exhaustible or environmentally harmful energy carriers and other instruments to this end would contribute greatly to the attractivity of RES investment both in terms of national economy and from the viewpoint of the private investor. Renewable energies will play an important role in the hardware and services sectors of the energy market in the decades to come. Long-term promotion of market introduction programmes and unequivocal energy-political aims on the part of the government are needed if the German industry is to have a share in this growing market and be able to offer internationally competitive products [de

    By the end of the 21 century, according to United National projections, the number of people on the earth is likely to have approximately doubled. How can a world of 10 to 12 billion people be provided with adequate supplies of energy, cleanly, safely and substantially? There is a growing consensus that renewable energy sources will be a very important part of the answer. The growing interest in 'renewables' has been prompted in part, by increasing concern over the pollution, resource depletion and possible climate change implications of our continuing use of conventional fossil and nuclear fuels. But recent technological developments have also improved the cost-effectiveness of many of the renewables, making their economic prospects look increasingly attractive. It describes the achievements and progress made in hydropower, biomass conversion, geothermal, solar thermal technology, wind energy conversion and the increasing usage of photovoltaics. It is evident that global warming is setting in and is going to change the climate as well as the terrain of many countries unless drastic measures are taken. The Kyoto meeting emphasised the importance of limiting CO 2 emissions and to abide by some form of agreement to reduce emissions. Present study concludes that renewable energy penetration into the energy market is much faster than was expected in recent years and by 2030, 15-20 percent of our prime energy will be met by renewable energy.

    Full Text Available The use of artificial neural networks (ANNs in various applications has grown significantly over the years. This paper compares an ANN based approach with a conventional on-off control applied to the operation of a ground source heat pump/photovoltaic thermal system serving a single house located in Ottawa (Canada for heating and cooling purposes. The hybrid renewable microgeneration system was investigated using the dynamic simulation software TRNSYS. A controller for predicting the future room temperature was developed in the MATLAB environment and six ANN control logics were analyzed.The comparison was performed in terms of ability to maintain the desired indoor comfort levels, primary energy consumption, operating costs and carbon dioxide equivalent emissions during a week of the heating period and a week of the cooling period. The results showed that the ANN approach is potentially able to alleviate the intensity of thermal discomfort associated with overheating/overcooling phenomena, but it could cause an increase in unmet comfort hours. The analysis also highlighted that the ANNs based strategies could reduce the primary energy consumption (up to around 36%, the operating costs (up to around 81% as well as the carbon dioxide equivalent emissions (up to around 36%.

    When one talks of rural development, no doubt, the issue of rural energy is not far behind. As a significant component of any development strategy, rural energy is seen as the engine for growth that can bring about economic upliftment in the countryside. Many approaches to rural energy development have been tried. These approaches differ from country to country. But regardless of structure and approach, the goal remain essentially the same: to provide rural communities access to reliable energy services at affordable prices. In recent years, as global concern for the environment has increased, many governments have turned to renewable energy as a more environment friendly alternative to rural electrification. Technological advances in renewable energy application has helped to encourage this use. System reliability has improved, development costs have, to some extent been brought down and varied application approaches have been tried and tested in many areas. Indeed, there is huge potential for the development of renewable energy in the rural areas of most developing countries. At the rural level, renewable energy resources are almost always abundantly available: woodwaste, agricultural residues, animal waste, small-scale hydro, wind, solar and even sometimes geothermal resources. Since smaller scale systems are usually expected in these areas, renewable energy technologies can very well serve as decentralized energy systems for rural application. And not only for rural applications, new expansion planning paradigms have likewise led to the emergence of decentralized energy systems not only as supply options but also as corrective measures for maintaining end of line voltage levels. On the other hand, where renewable energy resource can provide significant blocks of power, they can be relied upon to provide indigenous power to the grids.

    2017-06-01

    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.

    Time Warner Cable (TWC), now Charter Communications (CC), partnered with the National Renewable Energy Laboratory (NREL) to assess the technical and economic potential for solar photovoltaic (PV), wind, and ground-source heat-pump systems at 696 TWC facilities. NREL identified 306 sites where adding a renewable energy system would provide cost savings over the project life-cycle. In general, the top sites have some combination of high electricity rates ($0.16-$0.29/kWh), significant state incentives, and favorable net-metering policies. If all projects were implemented via third-party power purchase agreements, TWC/CC would save $37 million over 25 years and meet 10.5% of their energy consumption with renewable energy. This paper describes the portfolio screening methodology used to identify and prioritize renewable energy opportunities across the TWC sites, as well as a summary of the potential cost savings that may be realized by implementing these projects. This may provide a template for other companies interested in identifying and prioritizing renewable energy opportunities across a large number of geographically dispersed sites. Following this initial portfolio analysis, NREL will be conducting in-depth analysis of project development opportunities at ten sites and evaluating off-grid solutions that may enable carbon emission reduction and grid independence at select facilities.

    Main electrical energy sources of Turkey are thermal and hydraulic. Most of the thermal sources are derived from natural gas. Turkey imports natural gas; therefore, decreasing usage of natural gas is very important for both economical and environmental aspects. Because of disadvantages of fossil fuels, renewable energy sources are getting importance for sustainable energy development and environmental protection. Among the renewable sources, Turkey has very high wind energy potential. The estimated wind power capacity of Turkey is about 83,000 MW while only 10,000 MW of it seems to be economically feasible to use. Start 2009, the total installed wind power capacity of Turkey was only 4.3% of its total economical wind power potential (433 MW). However, the strong development of wind energy in Turkey is expected to continue in the coming years. In this study, Turkey's installed electric power capacity, electric energy production is investigated and also Turkey current wind energy status is examined. (author)

    This research examines the causality (For the remainder of the paper, the notion of causality refers to Granger causality.) links among renewable energy consumption (REC), CO 2 emissions (CE), non-renewable energy consumption (NREC), and economic growth (GDP) using an autoregressive distributed lag model based on the pooled mean group estimation (ARDL-PMG) and applying Granger causality tests for a panel consisting of 22 African countries for the period between 1990 and 2011. There is unidirectional and irreversible short-run causality from CE to GDP. The causal direction between CE and REC is unobservable over the short-term. Moreover, we find unidirectional, short-run causality from REC to GDP. When testing per pair of variables, there are short-run bidirectional causalities among REC, CE, and GDP. However, if we add CE to the variables REC and NREC, the causality to GDP is observable, and causality from the pair REC and NREC to economic growth is neutral. Likewise, if we add NREC to the variables GDP and REC, there is causality. There are bidirectional long-run causalities among REC, CE, and GDP, which supports the feedback assumption. Causality from GDP to REC is not strong for the panel. If we test per pair of variables, the strong causality from GDP and CE to REC is neutral. The long-run PMG estimates show that NREC and gross domestic product increase CE, whereas REC decreases CE.

    This paper analyzes China's policy approach to renewable energies and assesses how effectively China has met the ideal of appropriate interactions between renewable energy policy and renewable energy industrial policy. First we briefly discuss the interactions between these two policies. Then we outline China's key renewable energy and renewable industrial policies and find that China's government has well recognized the need for this policy interaction. After that, we study the achievements and problems in China's wind and solar PV sector during 2005–2012 and argue that China's policy approach to renewable energies has placed priority first on developing a renewable energy manufacturing industry and only second on renewable energy itself, and it has not effectively met the ideal of appropriate interactions between renewable energy policy and renewable energy industrial policy. Lastly, we make an in-depth analysis of the three ideas underlying this policy approach, that is, the green development idea, the low-carbon leadership idea and indigenous innovation idea. We conclude that Chinas' policy approach to renewable energies needs to enhance the interactions between renewable energy policy and renewable energy industrial policy. The paper contributes to a deeper understanding of China's policy strategy toward renewable energies. -- Highlights: •Interactions between renewable energy policy and renewable energy industrial policy are discussed. •China's key renewable energy and renewable energy industrial policies are outlined. •Two empirical cases illustrate China's policy approach to renewable energies. •We argue that China needs to enhance the interactions between the two policies. •Three ideas underlie China's policy approach to renewable energies

The conclusion is that in this system, some elements of which appear to be controversial, it is not possible to reach the goal - a radical reduction of CO 2 emissions by 80% in total and 95% in electricity production until 2050, which the EU has set as emission reduction targets for this period. Therefore, a new system is now proposed that is based on a single objective function, CO 2 emissions. The process would be managed through taxes or fees on CO 2 , while the raised revenues would be returned to projects aimed at reducing CO 2 emissions, projects for enhancing energy efficiency, renewable energy sources projects and projects reducing emissions from fossil fuels. The paper outlines the basis of the concept of CO 2 tax or fee as a key measure to stimulate the lowering of emissions and gives an analysis of the impact of different rates of tax or fee on CO 2 emissions on the energy price. A critical analysis of the new model's impact on development of renewable energy sources and on improving energy efficiency in buildings was carried out. Also, there is an analysis of the impact of the new model on transport development. The introduction of the new model should clear the energy market from administrative limitations and privileged positions of renewable sources and should bring all back in the frame of market economy, no matter what source of energy for production of electricity we are dealing with. One limitation to the new model is translation of the current situation in to the new system, especially in the field of renewable energy sources and their protected position under the already concluded long-term contracts. The paper also elaborates the basis for the

    In late 1985, the Public Advisory Committees to the Environmental Council of Alberta began working toward a draft conservation strategy for Alberta. A prospectus was published and meetings and workshops held, the goal being a conservation strategy in place by 1992. This report is one of a series of discussion papers on relevant sectors such as agriculture, fish and wildlife, tourism, and energy production. This report focuses on the present and potential economic significance of renewable energy resources, excluding hydro power, and their capability to meet Alberta's demand. Renewable energy sources discussed include solar, wind, geothermal, biomass, and energy from waste, with economic significance and demand projections for each, as well as their interactions with conventional sources. Their use in low-temperature space heating, industrial process heat, liquid fuels, and electricity is also detailed. Current legislative and regulatory requirements for each of the renewables is given, as well as an attempt at policy formulation to deal with the use of renewables as a whole. 4 figs.

    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)

    The recent formation of the Quebec Association for the Production of Renewable Energy (l`Association quebecoise de la production d`energie renouvelable - AQPER) was announced. The Association is becoming the centre of the Quebec private electricity generation industry. By communicating the industry`s message to the public the organization gives much needed visibility to renewable resources, new forms of energy and sustainable development. The new group is an outgrowth of the former Quebec Association of Private Hydroelectricity Producers. In its new reincarnation, the organization represents all forms of renewables, small and medium hydro, wind, solar, forest and agricultural biomass and urban waste. With deregulation of the electricity market, specifically the creation of the Regie de l`energie` in Quebec, the wider role is a welcome boost for renewable energy development in the province. In one of its first actions the AQPER recommended that all hydroelectric sites up to 50 MW be reserved for development exclusively by the private sector, in conformity with the Quebec energy policy announced in 1996.

  15. Regulation - renewable energies finally liberated?

    2016-01-01

    Within the context defined by the new French policy for energy transition, notably in terms of share of renewable energies in final energy consumption, France seems to be somehow late in the development of these energies: about 1 GW of wind energy are installed each year when the expected pace would be 1,5 GW, and the photovoltaic market is shrinking. As the legal context is important, this article proposes an overview of the evolution of the French policy during the last four years which started with interesting measures. Recently, the government showed its will to liberate renewable energies from several constraints. Some legal procedures tend to slow down the development. Some advances could therefore be made, for example to make rules less complex and numerous. The different situations of the wind and biogas sectors are evoked, as well as new opportunities created by a new decree on investment planning

  1. Economic performance of grid-connected photovoltaics in California and Texas (United States): The influence of renewable energy and climate policies

    International Nuclear Information System (INIS)

    Sivaraman, Deepak; Moore, Michael R.

    2012-01-01

    Various public policies in the United States are providing financial incentives for installation and generation of electricity from renewable resources. This article examines the influence of investment subsidies, greenhouse gas (GHG) prices, and renewable energy credit (REC) prices on the economic performance of grid-connected photovoltaic (PV) systems. Our model integrates PV output, capacity-factor-based dispatch, and cost-benefit financial components to evaluate new PV installations in California and Texas. Relative to the base case, the benefit–cost ratio increases between 5–53% in California and 5–38% in Texas for the policy-derived cases of GHG and REC prices. The economic performance of PV is higher in California due to higher grid electricity prices and the profile of displaced marginal fuels. A sensitivity analysis demonstrates the electricity and GHG prices required to achieve profitability. A key element of the economic analysis demonstrates the importance of assessing the marginal fuels displaced by the PV system, not the average mix of displaced fuels, in terms of accurately monetizing the GHG abatement embodied in the displaced fuels. In California, for example, the discounted benefits derived from pollution abatement under the marginal displacement approach were 1.6–3.0 times higher than under the three average fuel mix cases. - Highlight: ► The effect of public policies on the economic performance of PV systems is analyzed. ► A PV output model, a dispatch model, and a cost-benefit model are integrated. ► The PV installations generally do not achieve positive profitability. ► A sensitivity analysis demonstrates the prices required to achieve profitability. ► The marginal fuels displaced by the PV system, not the average fuels, are relevant.

    The energy production, in Israel, is not sufficient to satisfy the country needs, that is perpetually growing. Today 96% of the energy consumption is imported, essentially with petroleum and coal. To reduce this energy dependence, the government encourages the scientific researches and innovations in the field of clean and renewable energies. The paper presents political and economical aspects of the management and the exploitation of the following energy resources, developed in Israel: fossil fuels with oil shales; solar energy; biomass; wind energy; geothermal energy and hydraulic energy.

  3. Are renewable energies too expensive?

    International Nuclear Information System (INIS)

    2015-01-01

    As hydroelectricity is known to be profitable, and as biomass displayed good results when used for heating buildings, the issue of the cost of electricity produced by wind and photovoltaic energies is still a matter of debate. This article outlines how to take different factors into account to assess a discount rate. These factors are location which determines wind and sun resource, the future prices of fossil energies, rates of interest, and so on. It indicates that ground based wind and solar farms now have a kWh cost which is close to that of fossil energies, and lower than that of nuclear energy when taking investment and operation cost into account. The production cost of renewable energies has been dramatically reduced during the last years and this trend will probably continue during the years to come. Thus, the article states that a 100 per cent renewable mix seems possible for France by 2050 without significant over-costs

    India has done a significant progress in the power generation in the country. The installed generation capacity was 1300 megawatt (MW) at the time of Independence i.e. about 60 years back. The total generating capacity anticipated at the end of the Tenth Plan on 31-03-2007, is 1, 44,520 MW which includes the generation through various sectors like Hydro, Thermal and Nuclear. Emphasis is given to the renewable energy programme towards gradual commercialization. This programme is looked after by the Ministry of Non-Conventional Sources of energy. Since the availability of fossil fuel is on the decline therefore, in this backdrop the norms for conventional or renewable sources of energy (RSE) is given importance not only in India but has attracted the global attention. The main items under RSE are as follows: (i) Hydro Power (ii) Solar Power (iii) Wind Power (iv) Bio-mass Power (v) Energy from waste (vi) Ocean energy, and (vii) Alternative fuel for surface transportation. Evolution of power transformer technology in the country during the past five decades is quite impressive. There are manufacturers in the country with full access to the latest technology at the global level. Some of the manufacturers have impressive R&D set up to support the technology. Renewable energy is very much promoted by the Chinese Government. At the same time as the law was passed, the Chinese Government set a target for renewable energy to contribute 10% of the country's gross energy consumption by 2020, a huge increase from the current 1%. It has been felt that there is rising demand for energy, food and raw materials by a population of 2.5 billion Chinese and Indians. Both these countries have large coal dominated energy systems in the world and the use of fossil fuels such as coal and oil releases carbon dioxide (CO2) into the air which adds to the greenhouse gases which lead to global warming.

    Renewable energies are considered as an essential element of any strategy for sustainable energy development. The poor in the developing world without access to modern energies are regarded as a major market for renewable energies. This short paper attempts to analyse whether such a niche is backed by any economic logic and whether renewable energy and the poor nexus could be a strategy for success. The paper suggests that contrary to the common belief, the economic logic behind the niche is unsound and that the nexus is not a recipe for success

    Any investment has a positive effect on employment: setting up an investment object involves a number of jobs. But in national economic terms, investments into renewable energies have an employment effect only if the investments are viewed within the context of the energy system as a whole. A global scenario for extending the use of renewable energies as it is outlined by the group 2010 is expected to have a positive effect on employment. Employment effects in connection with renewable energies are inferior to those associated with investments that are economical ex ante, such as many investments for enhancing energy efficiency.

    Highlights: • One of the most relevant debates, is related to energy and environmental issue. • The development of renewable energy usage is due to several factors. • Indeed challenges from a supply chain point of view are required. • Thorough survey on topics of supply chain and renewable energy has been conducted. • Findings are discussed against the backdrop of SCs as sustainable RE option. - Abstract: Actually, one of the most relevant debates, among both citizens that government, is related to energy and environmental issue. The development of renewable energy usage is due to several factors such as the political strategic decisions and geographical situation. Indeed the high development of renewable energies requires challenges from a supply chain point of view. In this paper, a thorough survey of the extant literature on the topic of supply chain (SC) and renewable energy (RE) has been conducted. English papers published on international peer-reviewed journals from 2003 to 2013 have been considered. Sustainable Supply Chain Management (SSCM) resolves the duality between environmental, economic and social aspects. Sustainable manufacturing practices play an essential role in promoting renewable energy development and commercialization; this will require significant changes to the industry’s traditional Supply Chain Management and business model. The aim of the paper is investigate literature insights useful to increase the performance and overcome barriers to the RE supply chain development. Like many typical supply chains, also supply chain related to RE includes elements such as: physical, information, and financial flows. The present research is useful to individualize characteristics of a RE supply chain. Moreover, the research is useful improve the performance of RE supply chain in some aspects like: • better control supply chain costs to make renewable energy more affordable; • manage supply chain to address weakened demand in the near

    2016-01-01

    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.

    Energy resources, the basic input in every area of the economy, have a fundamental function for society's welfare. Traditional energy resources are, however, rapidly decreasing. Energy supply has been falling behind in meeting global demand, and is causing increased focus on efficiency and economy concepts in recent energy policies. Since the existing energy resources are not spread evenly among the countries, but instead are concentrated in certain regions and countries, a monopolistic situation arises. Equally, supply assurance is an issue, since the energy supply is held by certain regions and countries who have monopolistic pricing power. Both the EU and many other countries are studying how to marketize energy. This book focuses on the importance of energy and the problems posed by it. It will be useful for the academic community, related sectors and decision makers.

    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. 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

    We study the transition between non-renewable and renewable energy sources with adjustment costs over the production capacity of renewable energy. Assuming constant variable marginal costs for both energy sources, convex adjustment costs and a more expensive renewable energy, we show the following. With sufficiently abundant non-renewable energy endowments, the dynamic equilibrium path is composed of a first time phase of only non-renewable energy use followed by a transition phase substituti...

  5. Curtailment of renewable generation: Economic optimality and incentives

    International Nuclear Information System (INIS)

    Klinge Jacobsen, Henrik; Schröder, Sascha Thorsten

    2012-01-01

    The loss from curtailing generation based on renewable energy sources is generally seen as an unacceptable solution by the public. The main argument is that it is a loss of green energy and an economic loss to curtail generation with near zero marginal costs. However, this view could lead to overinvestment in grid infrastructure and underinvestment in renewable energy sources. This article argues that some curtailment of fluctuating (variable) generation is optimal. We address the possible contributions to total curtailment from involuntary and voluntary curtailment. The costs of curtailment in terms of lost generation are discussed based on market price and support levels including the rationale for compensating generators for losses. The extent of actual curtailment is illustrated by examples from different global markets. In general, both the value of the curtailed energy and the amount of curtailed energy relative to total fluctuating generation is low but rising. Single generators may be affected considerably if insufficient compensation measures are in place. In the future, optimal curtailment will increase along with an increased share of fluctuating renewable generation. Extending renewable generation comparatively cheaply can be achieved by the installation of additional capacity at offshore locations until optimal curtailment levels are reached. - Highlights: ► Curtailment of renewable generation can be optimal. ► Voluntary and involuntary curtailment categories. ► Compensation for involuntary curtailment should be provided. ► Asymmetrical balancing price provides incentive for voluntary curtailment. ► Network enforcement costs can be reduced per renewable generation.

  6. Towards sustainable development in Austria. Renewable energy contributions

    Besides energy conservation, the exploration of renewable energy sources, in particular biomass and solar energy, are central aspects of the Austrian energy policy, regarded as an optimal option for achieving CO2-emission reduction objectives. The market penetration of Renewable Energy Technologies in the last twenty years was supported by the Austrian Energy Research Programme. The result of successful developments of biomass heating, solar thermal, solar electrical and wind energy technologies is the key for the market development of these renewable energy technologies. With the market penetration of renewable energy technologies new business areas were established and employment created. Today, some renewable energy technologies in Austria have reached economic competitiveness. Some technologies not reached commercialisation, and need more development to improve efficiency, reliability and cost to become commercial. This would include material and system development, pilot plants or field experiments to clarify technical problems, and demonstration plants to illustrate performance capabilities and to clarify problems for commercialisation

  7. Cool energy. Renewal solutions to environmental problems

    International Nuclear Information System (INIS)

    Brower, M.

    1992-01-01

    This book begins with a chapter describing some of the economic and environmental consequences of America's fossil-fuel-based economy. It makes the case that, despite some progress in reducing pollution from fossil fuels, no lasting cure for the deteriorating environment - in particular, the looming threat of global warming - is possible without developing alternative fuel sources. That renewable energy can provide the bulk of the new supplies needed is the theme of the second chapter, which discusses the relative advantages of these resources compared to fossil fuels and nuclear power and evaluates their long-term potential. The bulk of the book considers five broad categories of renewable energy sources: solar, wind, biomass (plant matter), rivers and oceans, and geothermal. For each of these sources, the book describes its current application, discusses its costs, analyzes new technologies under development, and assesses its positive and negative environmental impacts. This book shows the vital role renewable sources can and should play in America's energy future. It cites studies indicating that, with the right policies, renewable energy could provide as much as half of America's energy within 40 years, and an even larger fraction down the road. Such a rapid shift from existing energy sources would be dramatic but not unprecedented. In 1920, coal supplied 70% of US energy, but within 40 years its share had dropped to just 20% as oil and natural gas use increased. Sooner or later, oil and natural gas will also fade in importance. The real question is when. This book makes the case that the time to move decisively toward a renewable energy economy has arrived

    The production of renewable energy in agricultural biogas plants is being widely criticized because-among other things-most of the feedstock comes from purpose-grown crops like maize. These activities (generously subsidized in the Czech Republic) generate competitive pressure to other crops that are used for feeding or food production, worsening their affordability. Unique pretreatment technology that allows substitution of the purpose-grown crops by farming residues (such as husk or straw) was built 6 years ago on a commercial basis in Pěčín (Czech Republic) under modest funding and without publicity. The design of the concept; financial assessment and moral viewpoint were analyzed based on practical operating data. It showed that the apparatus improves economic, environmental and moral acceptance as well. However, according to the government's view, public funding for this type of processing was shortened, "because waste materials represent a lower cost". The impact of such governance was analyzed as well.

    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.

    2004-01-01

    Around the globe, developing countries have reported different cases of successfully implemented renewable energy program supported by bilateral or multilateral funding. In developing countries subsidy has played a big role in renewable energy program marketing and whether this will lead to sustainable development is yet to be determined. The adoption of implementation strategies that will support sustainable development and overcoming barriers that hinder expansion of renewable energy technologies still remains as a big challenge to stake holders involved in promotion of renewable energy resources in developing countries. In this respect, developing countries need to re-examine their environmental policy for promotion of renewable energy technologies in order to define its role in revitalization of their economics. This paper reviews by policy incentives for promotion of renewable energy technologies in the Islamic Republic of Iran. Setting-up international collaborative business ventures between local industry in Iran and companies in developed countries is proposed as an implementation strategy that will appropriate diffusion of renewable energy technologies in the country. An organizational framework that may help to attain this objective is discussed and a structural model for renewable energy business partnership is presented. It is concluded that with appropriate policy formulations and strategies, renewable energy technologies can bring about the required socio-economic development in Iran

    2001-01-01

    The 'political quota-/certificate price market' system introduces an inefficient competition between energy robots, and weakens the increasingly important competition between equipment producers. It hampers the competition between investors by making it difficult for neighbours and local investors to invest in wind turbines. Due to its mono price character, it gives too high profits to wind turbine owners at very good wind sites, and not high enough to wind turbine owners at poor wind sites. The 'political quota-/certificate price market' system is very far from being a market model, as the RE amount is politically decided and the certificate market price is also political influenced. The conclusion, therefore, is that it is time to find a RE governance model that considers the specific needs and characteristics of RE technologies. The present analysis strongly indicates that a 'political price-/amount market' model in this connection is far better than the 'political quota-/certificate price market' model. Furthermore, a common EU model, based on the principle of site efficiency, would be much more flexible, cheaper and easier to pursue than the 'political quota-/certificate price market', or mono price model, which is designed for uranium and fossil fuel technologies, and represents a governance model designed for the technologies of yesterday.

    Our current fossil-fuel-based system is causing potentially catastrophic changes to our planet. The quest for renewable, nonpolluting sources of energy requires us to understand, predict, and ultimately control matter and energy at the electronic, atomic, and molecular levels. Light-source facilities - the synchrotrons of today and the next-generation light sources of tomorrow - are the scientific tools of choice for exploring the electronic and atomic structure of matter. As such, these photon-science facilities are uniquely positioned to jump-start a global revolution in renewable and carbonneutral energy technologies. In these pages, we outline and illustrate through examples from our nation's light sources possible scientific directions for addressing these profound yet urgent challenges.

    2006-01-01

    The global call for more and more penetration of renewable energy sources in the energy mix for several countries driven by various different motives including the desire for attaining sustainable development through the use of these renewable sources, for decreasing pollution, trying to decrease dependency on imported fuels or to exploit the locally available renewable resources, this call has not been satisfactorily responded to, partially, it is believed here, due to the lack of awareness and adequate manpower qualifications in these sources at the different levels of decision making. Energy education in many countries is still not so dynamic to coup with the ever changing circumstances and developments related to the demand, supply, technologies, economics policies as well as environmental aspects this is more noticed in the world developing countries, with other related obstacles facing the desired and needed wider application of renewable energy sources. The paper will try to handle this situation, analyzing its components, citing some examples of good fruitful practice in this connection, and drawing some recommendations that may help in improving the same

    This report summarizes the completion of four renewable energy installations supported by California Energy Commission (CEC) grant number CEC Grant PIR-11-005, the US Department of Energy (DOE) Assistance Agreement, DE-EE0003070, and the Sacramento Municipal Utility District (SMUD) Community Renewable Energy Deployment (CRED) program. The funding from the DOE, combined with funding from the CEC, supported the construction of a solar power system, biogas generation from waste systems, and anaerobic digestion systems at dairy facilities, all for electricity generation and delivery to SMUD’s distribution system. The deployment of CRED projects shows that solar projects and anaerobic digesters can be successfully implemented under favorable economic conditions and business models and through collaborative partnerships. This work helps other communities learn how to assess, overcome barriers, utilize, and benefit from renewable resources for electricity generation in their region. In addition to reducing GHG emissions, the projects also demonstrate that solar projects and anaerobic digesters can be readily implemented through collaborative partnerships. This work helps other communities learn how to assess, overcome barriers, utilize, and benefit from renewable resources for electricity generation in their region.

  20. Renewable energy policy. Into the mainstream

    International Nuclear Information System (INIS)

    2003-01-01

    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 study establishes the link between the growing wind market and the emerging hydrogen market of the European Union, in a so-called 'wind-hydrogen strategy'. It considers specifically the diversion of wind electricity, as a wind power control mechanism in high wind penetration situations, for the production of renewable electrolytic hydrogen - a potentially important component of a renewable hydrogen-inclusive economy. The analysis examines the long-term competitiveness of a wind-hydrogen strategy via cost-benefit assessment. It indicates the duration and extent to which (financial) support, if any, would need to be provided in support of such a strategy, and the influence over time of certain key factors on the outcome

  3. Renewable Energies: How Far Can We Go?

    International Nuclear Information System (INIS)

    Philibert, C.

    2011-01-01

    A little over five years ago, in January 2006, Futuribles devoted a sizeable special number to energy prospects and the greenhouse effect (no. 315). These were already troubling times and the gloomy prospects for the development of energy resources and the problematic of climate change were analysed in a number of articles. According to certain experts, 'peak oil' was already reached in that same year of 2006: that is to say, oil production was thought to be at its height and would subsequently be stagnating before a (more or less rapid) decline. Furthermore, gas production ought to reach a ceiling around 2025-2030, as Jean Laherrere showed in these columns last April (no. 373). In this context and given the undeniable efforts to be made to limit global warming, it has become essential, on the one hand, to act to control energy use and, on the other, to look to other sources of energy production - this second option being doubtless easier to implement than reducing consumption. Incontestably, renewable energies have an essential future role to play in the diversification of the energy mix and its orientation towards sustainable development. Cedric Philibert, a specialist in these forms of power within the International Energy Agency, here outlines their potential and the place they might occupy in years to come. After presenting the IEA's scenarios to 2035 and 2050 (which reveal the need for proactive policies to promote renewable energies), he focuses on the two major strands in this sector: wind power and solar energy. He then goes on to the question of what is meant by 'renewable': are these energies 100% renewable or have the supplies to be supplemented, the resources to be stored etc.? He analyses the role renewable energies could play in buildings and in the various sectors of industry and transport and under what technical conditions this might occur. Lastly, Philibert examines the economic aspects: what costs for what benefits? He shows, in substance, that

    The main goal of Latvian energy policy is to ensure safe and environmentally friendly long-term energy supply at cost-effective prices, contributing to enhance competitiveness, and to ensure safe energy transit. The Latvian Parliament approved an Energy Efficiency Strategy in 2000. Its objective is to decrease energy consumption per unit of GDP by 25% by 2010. Awareness raising, implementation of standards and economic incentives for self financing are the main instruments to increase energy efficiency, mentioned in the strategy. Latvia, as many other European Union member states, is dependent on the import of primary energy resources. The Latvian Renewable Energy strategy is still under development. The only recent study on RES was developed in the framework of a PHARE program in year 2000: "Renewable energy resource program", where three main objectives for a future RES strategy were proposed: 1. To increase the use of wood waste and low value wood and forest residues. 2. To improve efficiency of combustion technologies and to replace outdated plants. 3. To increase the use of renewables in Combined Heat and Power plants (CHP). Through the Renewable Energy and Energy Efficiency Partnership, partners will develop a set of new shared activities, and coordinate and strengthen existing efforts in this area.

    2013-02-01

    Waste-to-energy (WTE) technology burns municipal solid waste (MSW) in an environmentally safe combustion system to generate electricity, provide district heat, and reduce the need for landfill disposal. While this technology has gained acceptance in Europe, it has yet to be commonly recognized as an option in the United States. Section 1 of this report provides an overview of WTE as a renewable energy technology and describes a high-level model developed to assess the feasibility of WTE at a site. Section 2 reviews results from previous life cycle assessment (LCA) studies of WTE, and then uses an LCA inventory tool to perform a screening-level analysis of cost, net energy production, greenhouse gas (GHG) emissions, and conventional air pollution impacts of WTE for residual MSW in Boulder, Colorado. Section 3 of this report describes the federal regulations that govern the permitting, monitoring, and operating practices of MSW combustors and provides emissions limits for WTE projects.

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

    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.

    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 EurObserv'ER policy profiles give a snapshot of the renewable energy policy in the EU Member States. The promotion of renewable electricity in Romania relies primarily on a renewable quota scheme. Since 2017 the scheme has been closed for new projects. Renewable heating and cooling is promoted through investment subsidies. Renewable energy sources in the transport sector are promoted by a bio-fuels quota scheme and indirectly through a subsidy scheme for the purchase of electric vehicles

    The IEA Implementing Agreement for Renewable Energy Technology Deployment (IEA-RETD) investigated the opportunities for coupling renewable energy systems with fresh water supply systems. The four main conclusions of the scoping study, carried out by Ecofys, are: (1) Fresh water production based on desalination technologies provide most options for synergies with renewable energy production; (2) Linking desalination to renewable sources is currently not economically viable; (3) There is a large potential for small scale (decentralised) desalination plants; (4) Current commercially-sized desalination technologies are in need of a constant operation point. Reverse osmosis and thermal membrane technologies might give future synergies as deferrable load.

    As the publication shows, the public discussion in Germany is increasingly focusing on the cost of the promotion of renewable energy sources. Critical comments state that the EEG (Renewables Act) accounts for most of the recent electricity rate increases and also does not contribute to climate protection. This background paper of the Federal Environmental Office stresses the role of the EEC for climate protection and its effects on price trends in electricity supply. The resulting financial burden for the German citizens and industry is investigated, and it is discussed whether public funding of renewable energy sources is indeed beneficial for the German economy on the whole.

  6. Economic Feasibility Analysis for Renewable Energy Project Using an Integrated TFN–AHP–DEA Approach on the Basis of Consumer Utility

    Directory of Open Access Journals (Sweden)

    2017-12-01

    Full Text Available A renewable energy (RE project has been brought into focus in recent years. Although there is quite a lot of research to assist investors in assessing the economic feasibility of the project, because of the lack of consideration of consumer utility, the existing approaches may still cause a biased result. In order to promote further development, this study focuses on the economic feasibility analysis of the RE project on the basis of consumer utility in the whole life cycle. Therefore, an integrated approach is proposed, which consists of triangular fuzzy numbers (TFNs, an analytic hierarchy process (AHP and data envelopment analysis (DEA. The first step is to determine the comprehensive cost index weights of DEA by TFN–AHP. Secondly, to solve the problem, the first DEA model, which is proposed by A. Charnes, W. W. Cooper and E. Rhodes (C2R, is established to calculate the DEA effectiveness. Then, the third task involves designing a computer-based intelligent interface (CBII to simplify realistic application and ensure performance efficiency. Finally, a solar water heater case study is demonstrated to validate the effectiveness of the entire method’s system. The study shows that this could make investors’ lives easier by using the CBII scientifically, reasonably and conveniently. Moreover, the research results could be easily extended to more complex real-world applications.

    Greenhouse crop evolution if from one hand improves the quality of products and productive cycles, from another hand cause negative effects on the natural resources, the environment and the economy of the country. Although renewable energies already feature to some extent in the European Union's regional, the 2007-2013 Structural Funds package could be the occasion to increase the weight given to RES within the energy programmes for less favoured regions (particularly in ex-objective 1 areas). In those areas, greenhouse crop sector is particularly developed as agriculture industrial activity. According to numerous investigations, agricultural greenhouse consumption for greenhouse acclimatization represents approximately between 2% to 6% of the E U's-27 total energy consumption. This report is intended to give a general overview to the potential of renewable energy and technology in Italy, particularly geothermal, wind and solar (thermic and photovoltaic) as energy for greenhouse crop sector. RES have a high potential for developing of indigenous resources, service activities, new job creation and reducing Co2 emissions. [it

    In order to support North and West China’s RE (RE) development and enhance accommodation in reasonable high level, HVDC’s traditional operation curves need some change to follow the output characteristic of RE, which helps to shrink curtailment electricity and curtailment ratio of RE. In this paper, an economic benefit analysis method based on production simulation (PS) and Analytic hierarchy process (AHP) has been proposed. PS is the basic tool to analyze chosen power system operation situation, and AHP method could give a suitable comparison result among many candidate schemes. Based on four different transmission curve combinations, related economic benefit has been evaluated by PS and AHP. The results and related index have shown the efficiency of suggested method, and finally it has been validated that HVDC operation curve in following RE output mode could have benefit in decreasing RE curtailment level and improving economic operation.

    The climate is changing, the worlds known fossil energy reserves are limited, and most economies are struggling to get out of a financial crisis. The UNs Intergovernmental Panel on Climate Change calls for new technologies, rapid commercialization, and rapid international diffusion as important tools to mitigate the climate change (IPCC 2007). Nations all over the world have allocated large funds to facilitate the development of renewable energy technologies and markets to secure the future supply of energy and to sustain economic growth (REN21 2009). Use of fossil fuel is the main source of humans contribution to global warming. At the same time, fossil fuel is probably the most important resource for economic development on a global scale (IEA 2009). With this as a backdrop, the objective of this PhD thesis is to investigate how technology-based companies act to commercialize and internationally diffuse technologies that may produce abundant clean, renewable energy. More specifically, I have assessed the emerging offshore renewable energy industries (offshore wind, wave, and tidal energy) as case industries to make the International Entrepreneurship literature more relevant for the current situation. The findings reveal extensive international activities at both the company level and industry level, even in phases in which the firms have yet to commercialize and industries have yet to enter the growth phase. These findings demand significant updates to theoretical models and convey several recommendations to mangers, investors, and policy makers. Managers should be aware of and master the new opportunities/threats identified. For investors, the findings provide implications for their valuation of new ventures. For policy makers, the findings open up a new landscape of political threats and opportunities as the battle to attract promising industries has begun earlier than previously prescribed.

    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.

  1. Renewable energy consumption and income in emerging economies

    2009-01-01

    Increased economic growth and demand for energy in emerging economies is creating an opportunity for these countries to increase their usage of renewable energy. This paper presents and estimates two empirical models of renewable energy consumption and income for a panel of emerging economies. Panel cointegration estimates show that increases in real per capita income have a positive and statistically significant impact on per capita renewable energy consumption. In the long term, a 1% increase in real income per capita increases the consumption of renewable energy per capita in emerging economies by approximately 3.5%. Long-term renewable energy per capita consumption price elasticity estimates are approximately equal to -0.70.

    This article examines different modes of electrolyzers in two future scenarios of the German energy system. It turns out that hydrolyzers need a high utilization to pay for themselves. An economic operation in 2030 in the scenario of moderate expansion of renewable energies is not possible. At strong expansion the investment is profitable when high revenues from secondary control power provision can be achieved. Generally it is clear that the secondary control power provision and also the direct sales of hydrogen in industry or in the transport sector allows higher revenues than the storage and reconversion. [German] Der Beitrag untersucht verschiedene Betriebsweisen von Elektrolyseuren in zwei Zukunftsszenarien des deutschen Energiesystems. Es zeigt sich, dass Elektrolyseure eine hohe Auslastung benoetigen, um sich zu amortisieren. Ein wirtschaftlicher Betrieb ist bis 2030 im Szenario mit moderatem Ausbau Erneuerbarer Energien nicht moeglich. Bei starkem Ausbau rentiert sich die Investition, wenn hohe Erloese aus Sekundaerregelleistungsvorhaltung erzielt werden koennen. Allgemein wird deutlich, dass die Sekundaerregelleistungsvorhaltung und auch der direkte Absatz von Wasserstoff in der Industrie oder im Verkehrssektor hoehere Erloese ermoeglichen als die Speicherung und Rueckverstromung.

The power generated would supply part of the energy requirements of the high-rise building where the system is installed. The system integrates and optimizes several green technologies; including urban wind turbine, solar cell module and rain water collector. The design was conceptualized based on the experiences acquired during the development and testing of a suitable wind turbine for Malaysian applications. It is compact and can be built on top of high-rise buildings in order to provide on-site renewable power to the building. It overcomes the inferior aspect on the low wind speed by channeling and increasing the speed of the high altitude free-stream wind through the power-augmentation-guide-vane (PAGV) before it enters the wind turbine at the center portion. The shape or appearance of the PAGV that surrounds the wind turbine can be blended into the building architecture without negative visual impact (becomes part of the building). The design improves the starting behavior of wind turbines. It is also safer to people around and reduces noise pollution. The techno-economic analysis is carried out by applying the life cycle cost (LCC) method. The LCC method takes into consideration the complete range of costs and makes cash flows time

  6. Renewable Energy versus Nuclear Power (Summary)

    The European Union is divided on the issue of electricity production. While there is consensus that generation technologies need to be low on greenhouse gas- emissions, the question of whether to use renewables or nuclear to meet this power demand is highly controversial. Both options still require financial support and this is not going to change in the near future. This raises the question of where our money should be invested in order to achieve greater economic efficiency: into support for renewable energies (RE) or support for nuclear power plants? This paper sets out to answer this question. The detailed model-based prospective scenario assessment performed in this study provides the basis for estimating future cost developments. After discussing the existing support schemes for renewables, the paper compares these with a nuclear model. The recent state aid case for the construction of the nuclear power plant Hinkley Point in United Kingdom serves as the model for the nuclear option. New milestone in nuclear state aid: Hinkley Point It is planned to construct two additional reactors at Hinkley Point. The EU estimates the total capital needed for construction at € 43 billion. The UK government intends to grant state aid for this project; in accordance with EU state aid rules, the suggested state aid scheme was submitted to the EU Commission for approval as public funds would be used for a company. A central part of the state aid scheme is the Contract for Difference which runs for 35 years. According to this contract, the state commits to compensating any difference between the electricity market price (reference price) and the negotiated Strike Price. Consequently, the plant operator, NNB Generation Company Limited (NNBG), has received a long term price guarantee which, in principle, is analogous to the feed-in tariffs commonly used to support renewable energies. The Strike Price for the first unit to be constructed has been set at € 108 per MWh (with

    This paper briefly reviews the need for renewable power generation and describes a medium-power Autonomous Renewable Energy Conversion System (ARECS), integrating conversion of wind and solar energy sources. The objectives of the paper are to extract maximum power from the proposed wind energy conversion scheme and to transfer this power and the power derived by the photovoltaic system in a high efficiency way to a local isolated load. The wind energy conversion operates at variable shaft speed yielding an improved annual energy production over constant speed systems. An induction generator (IG) has been used because of its reduced cost, robustness, absence of separate DC source for excitation, easier dismounting and maintenance. The maximum energy transfer of the wind energy is assured by a simple and reliable control strategy adjusting the stator frequency of the IG so that the power drawn is equal to the peak power production of the wind turbine at any wind speed. The presented control strategy also provides an optimal efficiency operation of the IG by applying a quadratic dependence between the IG terminal voltage and frequency V {approx} f{sup 2}. For improving the total system efficiency, high efficiency converters have been designed and implemented. The modular principle of the proposed DC/DC conversion provides the possibility for modifying the system structure depending on different conditions. The configuration of the presented ARECS and the implementation of the proposed control algorithm for optimal power transfer are fully discussed. The stability and dynamic performance as well as the different operation modes of the proposed control and the operation of the converters are illustrated and verified on an experimental prototype.

  2. Renewable energy policy and public perceptions of renewable energy. A cultural theory approach

    International Nuclear Information System (INIS)

    West, J.; Bailey, I.; Winter, M.

    2010-01-01

    Public opposition to the siting of renewable energy (RE) facilities and public reluctance to invest in RE remain key obstacles to the expansion of the renewables sector in the UK and a number of other European countries. Although there is a growing body of qualitative research on factors that inform public attitudes towards RE, the majority of studies have tended to be quantitative and to view 'the public' and 'public opinion' as homogeneous wholes. This study uses a cultural theory framework and focus groups conducted in the South West UK to develop deeper understandings of how individuals' worldviews can inform opinions and behaviour in relation to RE. These findings are used to explore ways in which government policies on RE might be tailored to engender greater public support and participation. Issues discussed include the provision of economic incentives, information on climate change and RE, linking renewables to overall energy behaviour, and landscape aesthetics. (author)

    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

    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

    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

    As a result of the globalization of knowledge, shortening of the innovation cycle and the aggravation of the price situation, the diffusion of innovation has accelerated. The protection of innovation has become even more important for companies in technologyintensive industries. Legal and actual patent right strategies complement one another, in order to amortize the investment in product development. Climate change is one of today’s truly global challenges, affecting all aspects of socio-economic development in every region of the world. Technology development and its rapid diffusion are considered crucial for tackling the climate change challenge. At the global level, the last decades have seen a continuous expansion of inventive activity in renewable energy technologies. The growth in Renewable Energy (RE) inventions has been much faster than in other technologies, and RE today represents nearly 6% of global invention activity, up from 1.5% in 1990. This paper discusses about global innovation activity in the last five years in the renewable energy sector and describes the Innovation and Technology Management process for supporting managerial decision making.

    1999-01-01

    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.

    International Nuclear Information System (INIS)

    2000-01-01

    According to Shell, by 2050, renewable energy sources may supply over 50% of the energy, worldwide. This concentration on renewable energy sources is primarily due to the intensified environmental demands. The UN climate panel has estimated that to avoid irreversible climate change it is necessary to reduce the global emissions of CO2 by 50 to 60% during the next 100 years. Biomass energy includes a number of biological raw materials from forestry and agriculture. The forests provide wood, wood chips, bark, branches and treetops, and from agriculture, straw. Although biomass energy is not entirely pollution-free, it is renewable and CO2-neutral as long as growth and consumption are in balance. In Norway, the total annual growth of available biomass corresponds to about 80 TWh. The technical potential is estimated to 30 TWh per year, allowing for operationally reasonable ways of producing the biomass. However, there is competition for the biomass since it is used by the wood processing industry. The use of biomass and waste for energy generation varies considerably among the Nordic countries. In Denmark, agriculture dominates and large quantities of straw are burned in cogeneration plants. Sweden and Finland have well-developed forest industries, and the wood processing industry in these countries uses much more biomass fuel (bark, fibre mud, black liquor) than the Norwegian wood processing industry. In Norway, more energy can be obtained by retrofitting old hydroelectric plants such as by installing a flexible liner in existing tunnels. This improves energy flexibility and increases energy production without negative environmental consequences. The potential for wind power is larger in Norway than in Denmark and Germany. The cost of wind power has fallen considerably as a consequence of the technological development of the sector

    This publication reports on how the steadily increasing costs caused by the Renewable Energy Law (EEG) have brought the German strategy for the expansion of renewable energies under criticism. According to theories of regulatory economic policy, which state that politico-economic incentives of this kind must necessarily result in an inefficient allocation of scarce resources, this cost increase can be interpreted as a direct consequence of the price intervention. The present publication takes a critical stance on this viewpoint, developing for its purpose a new position on regulatory policy referred to as the evolutionary cybernetic theory of economic policy. It starts out from the works of F.A. von Hayek, which it then takes a significant step further however. The author argues that price interventions can be meaningful strategies of economic policy as long as they are aimed at a temporary initiation of market development towards sustainability and efficiency. Based on this model conception of a shrewd pricing strategy the publication undertakes an analysis from the perspective of regulatory policy of the German subsidisation of renewable energies. In the process it not only reveals errors in design of the EEG but also makes a proposal for an amendment that could be effective in cutting through the present price dynamics. In presenting its recommendation of a self-steering expansion policy the publication not only contributes to the further development of an evolutionary cybernetic theory of economic policy but addresses the urgent problem of how to wisely use regulatory policy to create pricing strategies which serve the expansion of renewable energies.

    Contreras Cordero, Francisco Jose

    Use of diesel generators in remote communities is economically and environmentally unsustainable. Consequently, researchers have focussed on designing hybrid renewable energy systems (HRES) for distributed electricity generation in remote communities. However, the cost-effectiveness of interconnecting multiple remote communities (microgrids) has not been explored. The main objective of this thesis is to develop a methodology for optimal design of HRES and microgrids for remote communities. A set of case studies was developed to test this methodology and it was determined that a combination of stand-alone decentralized HRES and microgrids is the most cost-effective power generation scheme when studying a group of remote communities.

One of the largest tidal ranges within the world is contained within the Bay of Fundy, which holds power potential in the form of wind, wave and tidal energy. A strategic environmental assessment (SEA) on the Bay of Fundy's potential marine renewable energy was published in 2008. An assessment of the social, economic, and environmental effects and factors linked with possible development of renewable energy sources in the Bay Fundy was published. Twenty-nine recommendations were offered, including the creation of marine renewable energy legislation incorporating sustainability principles. This discussion paper described the policy drivers and opportunities in Nova Scotia for marine renewable energy sources as well as the challenges and relevant subject areas that should be considered when creating marine renewable energy legislation and policy. Specific challenges that were discussed included a policy approach to development; multiple jurisdictions; Aboriginal issues; economic factors; environmental impacts; occupational and operation safety; allocation of rights; and regulatory issues. It was concluded that if the marine renewable energy resource was going to be created with the possibility of providing commercial electricity generation, a coordinated legislative framework should be established. refs., tabs.
