    Full Text Available The study presents a cost effective electricity generation portfolio for six island states for a 20-year period (2015–2035. The underlying concept investigates whether adding sizeable power capacities of renewable energy sources (RES options could decrease the overall costs and contribute to a more sustainable, indigenous electricity generation at the same time. Often, island states rely on fossil fuels which, apart from dependence on foreign resources, also includes an additional, significant transport cost. This is an extra motive to study the extent in which island states represent primary locations for RES technologies. For the aims of the present study an optimization model has been developed and following numerous runs the obtained results show that installing PV and battery capacities can delay-reduce the huge investments in fossil options in early periods. Thus, investment on RES can have a positive, long-term effect on the overall energy mix. This prompt development can happen without adding new subsidies but there is a need to address the existing socio-economic barriers with intelligent design of financing and economic instruments and capacity building as discussed in the conclusions.

    The structure of the energy industry and the planning of electrical networks are experiencing rapid changes under the combined action of social, technico-economical, environmental and trade pressures. Given the widening diversity of competing (demand and supply) options being offered to consumers, energy policy makers must establish a fair and consistent technico-economic methodology to compare the sustainability and natural synergies of energy options. Such an approach towards energy issues should allow renewable energies, energy efficiency and storage technologies to build strong alliances with information technology and take a major place in the long-term energy portfolio of societies. With examples of recent projects involving significant penetration of wind energy in electrical grids in Canada and abroad, the author presents the rationale for technico-economic comparison indicators that canadian policy makers need to take into account so as to bring the full advantage and value of promising renewable energy technologies to the canadian energy market. The merits of expanding the pace of the current Canadian GHG reduction program by granting all provinces, irrespective of their electricity market structure or generation mix, an equal opportunity to invest in RE projects contributing to the national goal are presented. In this regard, the limitations of the prevailing accounting rules found in the Canadian GHG reduction program are analysed and corrections are proposed. (author)

    Thirty-four states had adopted Sustainable Energy Portfolio Standards (SEPS) or similar goals by the end of 2008, with 14 adoptions since 2006. There appears to be something trendy about SEPS and states may adopt SEPS when internal variables would indicate otherwise. This analysis extends the current discussion of SEPS adoption beyond internal variables, relying on innovation and diffusion theory. Logistic regression with SEPS adoption as the dependent variable is used to test internal determinants and diffusion measures for the years 1997-2008. Of the internal determinants variables, affluence and government ideology were found to be positive and significant. The results show that regional and neighbor diffusion variables are significant in SEPS adoption decisions-even when accounting for ideological distance from previous adopters.

  6. Energy Portfolio Assessment Tool (EPAT): Sustainable Energy Planning Using the WEF Nexus Approach - Texas Case Study

    The future energy portfolio at the national and subnational levels should consider its impact on water resources and environment. Although energy resources are the main contributors to the national economic growth, these resources must not exploit other primary natural resources. A study of the connections between energy and natural systems, such as water, environment and land is required prior to proceeding to energy development. Policy makers are in need of a tool quantifying the interlinkages across energy, water and the environment, while demonstrating the consequent trade-offs across the nexus systems. The Energy Portfolio Assessment Tool (EPAT) is a tool that enables the policy maker to create different energy portfolio scenarios with various energy and electricity sources, and evaluate the scenario's sustainability environmentally and economically. The Water-Energy-Food nexus systematic approach is the foundation of the EPAT framework. The research evaluates the impact of the current and projected Texas energy portfolios on water and the environment, taking into consideration energy production, electricity generation and policy change. The three scenarios to be assessed include EIA projections for energy production, and EIA projections for electricity generation with and without the Clean Power Plan (CPP). Each scenario is accompanied by tradeoffs across water, land, emissions, energy revenue and electricity cost. The CPP succeeds in mitigating the emissions of the electricity portfolio, but leads to an increase in water consumption and land use. The cost of electricity generation is almost identical with and without environmental conservation. Revenue from energy production increased, but results are majorly influenced by commodity price. Therefore, conservation policies should move from the silo to the nexus mentality to avoid unintended consequences as improving one part of the nexus could end up worsening the other parts.

    The planning of electricity generation systems considers several factors that must be taken into account in order to design systems that are economical, reliable and sustainable. For this purpose, the Financial Portfolio Theory is applicable to the energy portfolio or the diversification of electricity generation technologies, such as is the combined cycle, wind, thermoelectric and nuclear. This paper presents an application of the Portfolio Theory to the national energy system, based on the total generation costs for each technology, which allows determining the average variance portfolio and the respective share of each of the electricity generation technologies considered, obtaining a portfolio of electricity generation with the maximum possible return for the risk taken in the investments. This paper describes the basic aspects of the Portfolio Theory and its methodology, in which matrices are implemented for the solution of the resulting Lagrange system. (Author)

  8. The incorporation of sustainability into the real estate investment portfolio

    This graduation report describes the findings of a research in the area of Real Estate Management, section Building Economics. The subject of the research relates to the added value of sustainable offices in the real estate investment portfolio. The question which is leading throughout this report is whether the extent of sustainability influences the financial performance of office buildings in the Netherlands. But on which grounds are these assumptions made? The gathered information compares actual energy consumption in relation to theoretical knowledge of a governmental regulated energy performance scheme. To find an accurate answer a quantitative research has been conducted at a sustainability-driven organization, the Dutch Green Building Council (in short: DGBC). An extensive literature review provided the author with a solid background to investigate the relation of financial performance compared to sustainability features. This knowledge enabled him to define a hedonic pricing model and thus to look into financial benefits of better performing assets. This model is used to highlight significant locational, asset-related and sustainable features that act as predictors for offices. Especially the degree of sustainability comes to mind when this data is compared with actual consumption instead of theoretically defined through a standardized calculation. This resulted into recommendations and eventually discussions gathered at the end of this report. This report aims not only on the change of one's mind about the importance of sustainability but also on the added value of information flows for operational management.

    While engineered nanomaterials (ENMs) are increasingly incorporated in diverse applications, risks of ENM adoption remain difficult to predict and mitigate proactively. Current decision-making tools do not adequately account for ENM uncertainties including varying functional forms, unique environmental behavior, economic costs, unknown supply and demand, and upstream emissions. The complexity of the ENM system necessitates a novel approach: in this study, the adaptation of an investment portfolio optimization model is demonstrated for optimization of ENM use in renewable energy technologies. Where a traditional investment portfolio optimization model maximizes return on investment through optimal selection of stock, ENM portfolio optimization maximizes the performance of energy technology systems by optimizing selective use of ENMs. Cumulative impacts of multiple ENM material portfolios are evaluated in two case studies: organic photovoltaic cells (OPVs) for renewable energy and lithium-ion batteries (LIBs) for electric vehicles. Results indicate ENM adoption is dependent on overall performance and variance of the material, resource use, environmental impact, and economic trade-offs. From a sustainability perspective, improved clean energy applications can help extend product lifespans, reduce fossil energy consumption, and substitute ENMs for scarce incumbent materials.

    Understanding cosmic acceleration is one of the key science drivers for astrophysics and high-energy physics in the coming decade (2014 P5 Report). With the Large Synoptic Survey Telescope (LSST) and the Dark Energy Spectroscopic Instrument (DESI) and other new facilities beginning operations soon, we are entering an exciting phase during which we expect an order of magnitude improvement in constraints on dark energy and the physics of the accelerating Universe. This is a key moment for a matching Small Projects portfolio that can (1) greatly enhance the science reach of these flagship projects, (2) have immediate scientific impact, and (3) lay the groundwork for the next stages of the Cosmic Frontier Dark Energy program. In this White Paper, we outline a balanced portfolio that can accomplish these goals through a combination of observational, experimental, and theory and simulation efforts.

    2010-01-01

    This paper's results indicate that futures for crude oil, natural gas and unleaded gasoline fail to enhance the performance of representative energy stocks in terms of return to risk, but do decrease the overall level of risk exposure borne by passive equity investors. Our findings suggest that futures contracts on energy commodities are valuable to market participants with an interest in hedging against price fluctuations in energy markets by buy-and-hold strategies. However, this conclusion is reversed when one takes the perspective of traders whose core interests can be better approximated through the return to risk-bearing. In fact, this paper documents that return-to-risk maximizing agents are unlikely to profit from trading energy futures in addition to energy stocks. Moreover, futures for energy commodities fail to offer significant diversification gains with respect to energy stocks once investors adopt simple dynamic trading strategies that rely on readily available pricing information.

    Full Text Available Korea is a heavily energy-dependent country whose primary energy consumption ranks ninth in the world. However, at the same time, it promised to reduce carbon emission and planned to use more renewable energy. Thus, the objective of this study is to propose an optimal energy mix planning model in electricity generation from various energy sources, such as gas, coal, nuclear, hydro, wind, photovoltaic, and biomass, which considers more renewable and sustainable portions by imposing governmental regulation named renewable portfolio standard (RPS. This optimization model minimizes various costs such as construction cost, operation and management cost, fuel cost, and carbon emission cost while satisfying minimal demand requirement, maximal annual installation potential, and renewable portfolio standard constraints. Results showed that this optimization model could successfully generate energy mix plan from 2012 to 2030 while minimizing the objective costs and satisfying all the constraints. Therefore, this optimization model contributes more efficient and objective method to the complex decision-making process with a sustainability option. This proposed energy mix model is expected to be applied not only to Korea, but also to many other countries in the future for more economical planning of their electricity generation while affecting climate change less.

    Traditional management of electricity portfolios is focused on the day-ahead market and futures of longer maturity. Within limits, market participants can however also resort to the balancing energy market to close their positions. In this paper, we determine strategic positions in the balancing energy market and identify corresponding economic incentives in an analysis of the German balancing energy demand. We find that those strategies allow an economically optimal starting point for real-time balancing and create a marketplace for flexible capacity that is more open than alternative marketplaces. The strategies we proffer in this paper we believe will contribute to an effective functioning of the electricity market. (author)

    This paper presents United States energy portfolios for the year 2030, developed from seven different Perspectives. The Perspectives are characterized by different weights placed on fourteen defining values (e.g., cost, social acceptance). The portfolios were constructed to achieve three primary goals, energy independence, energy security, and greenhouse gas reductions. The portfolios are also evaluated over a comprehensive set of secondary criteria (e.g., economic growth, technical feasibility). It is found that very different portfolios based on very different defining values can achieve the three primary goals. Commonalities among the portfolios include reliance upon cellulosic ethanol, nuclear power, and energy efficiency to meet year 2030 energy demands. It is concluded that the US energy portfolio must be diverse and to achieve national energy goals will require an explicit statement of goals, a strong role for government, and coordinated action across society

    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.

    This paper outlines the approach to the evaluation of sustainability of current and future electricity supply options of interest for a major Swiss utility Axpo Holding AG. The motivation behind this effort has been to provide a solid basis for a state-of-the-art interdisciplinary assessment and use this framework within a dialog with a wide spectrum of stakeholders. The development and implementation of the methodology was coordinated by Axpo in co-operation with the Paul Scherrer Institut (PSI) and other scientific institutions. The evaluation covers environmental, social and economic dimensions of sustainability. Methods used include among others Life Cycle Assessment (LCA), Impact Pathway Approach (IPA) and Probabilistic Safety Assessment (PSA). The associated databases developed by PSI have been extensively used, subject to major extensions necessary for analysing the future technologies. Learning curves were employed for future cost estimates. Furthermore, particularly in the social area expert surveys were used. The results were aggregated using total (internal plus external) costs approach and Multi-criteria Decision Analysis (MCDA). For MCDA a set of criteria and the associated indicators was established. In total 75 indicators were quantified, including 11 environmental, 33 social and 31 economic. 18 current and 18 future technologies have been analysed including nuclear as well as fossil and renewable technologies. Total costs were estimated for these technologies providing a clear ranking with nuclear having the lowest costs and some of the renewable showing remarkable cost reductions until 2030. This ranking is partially controversial mainly due to the limited representation of social aspects in the total costs. The results of MCDA-applications involving elicitation of preferences from a relatively homogeneous stakeholder group, i.e. 85 employees of the Axpo Group (including also NOK, EGL, CKW and Axpo IT), are summarized.

    The Hopi Tribal Government as part of an initiative to ?Regulate the delivery of energy and energy services to the Hopi Reservation and to create a strategic business plan for tribal provision of appropriate utility, both in a manner that improves the reliability and cost efficiency of such services,? established the Hopi Clean Air Partnership Project (HCAPP) to support the Tribe?s economic development goals, which is sensitive to the needs and ways of the Hopi people. The Department of Energy (DOE) funded, Formation of Hopi Sustainable Energy Program results are included in the Clean Air Partnership Report. One of the Hopi Tribe?s primary strategies to improving the reliability and cost efficiency of energy services on the Reservation and to creating alternative (to coal) economic development opportunities is to form and begin implementation of the Hopi Sustainable Energy Program. The Hopi Tribe through the implementation of this grant identified various economic opportunities available from renewable energy resources. However, in order to take advantage of those opportunities, capacity building of tribal staff is essential in order for the Tribe to develop and manage its renewable energy resources. As Arizona public utilities such as APS?s renewable energy portfolio increases the demand for renewable power will increase. The Hopi Tribe would be in a good position to provide a percentage of the power through wind energy. It is equally important that the Hopi Tribe begin a dialogue with APS and NTUA to purchase the 69Kv transmission on Hopi and begin looking into financing options to purchase the line.

    Full Text Available In this paper, we extend Maslow’s need hierarchy theory and the two-level optimization approach by developing the framework of the Maslow portfolio selection model (MPSM by solving the two optimization problems to meet the need of individuals with low financial sustainability who prefer to satisfy their lower-level (safety need first, and, thereafter, look for higher-level (self-actualization need to maximize the optimal return. We illustrate our proposed model with real American stock data from the S&P index and conduct the out-of-sample analysis to compare the performance of our proposed Variance-CVaR (conditional value-at-risk MPSM with both traditional mean-variance and mean-CVaR models. Our empirical analysis shows that our proposed Variance-CVaR MPSM is not only sustainable, but also obtains the best out-of-sample performance in the sense that the optimal portfolios obtained by using our proposed Variance-CVaR MPSM obtain the highest cumulative returns in the out-of-sample period among the models used in our paper. We note that our proposed model is not only suitable to individuals with low financial sustainability, but also suitable to institutions or investors with high financial sustainability.

It presently has 50 loans and grants for non conventional renewable energy projects and ten grants for efficiency programs for $600 and $17 million respectively, representing 100 MW of power. The IDB is concerned with how to create a sustainable market for sustainable energy projects. The IDB is trying to work with government, private sector, NGOs, trading allies, credit sources, and regulators to find proper roles for such projects. He discusses how the IDB is working to expand its vision and objectives in renewable energy projects in Central and South America.

    Today, the increased consumption of energy in world, in addition to the risk of quick exhaustion of fossil resources, has forced industrial firms and organizations to utilize energy technology portfolio management tools viewed both as a process of diversification of energy sources and optimal use of available energy sources. Furthermore, the rapid development of technologies, their increasing complexity and variety, and market dynamics have made the task of technology portfolio selection difficult. Considering high level of competitiveness, organizations need to strategically allocate their limited resources to the best subset of possible candidates. This paper presents the results of developing a mathematical model for energy technology portfolio selection at a R&D center maximizing support of the organization's strategy and values. The model balances the cost and benefit of the entire portfolio.

    In a few years, Indonesia experienced difficulties in maintaining energy security, the problem is the decline in oil production from 1.6 million barrels per day to 861 thousand barrels per day in 2012. However, there is a difference condition in 2015 until the third week in 2016, world oil prices actually fell at the lowest price level since last 12 years. The decline in oil prices due to oversupply of oil by oil-producing countries of the world due to the instability of the world economy. Wave of layoffs in Indonesia is a response to the decline in oil prices, this led to the energy and mines portfolios Indonesia feared would not be more advantageous than the portfolio in other countries. In this research, portfolio analysis will be done on energy and mining in Indonesia by using stock price data of energy and mines in the period 26 November 2010 until April 1, 2016. It was found that the results have a wide effect of the market potential is high in the determination of the return on the portfolio energy and mines. Later, it was found that there are eight of the thirty stocks in the energy and mining portfolio of Indonesia which have a high probability of return relative to the average return of stocks in a portfolio of energy and mines.

    Eastern Coastal areas of China have been developing rapidly since the implementation of reforms and the opening of China's economic markets in 1978. As in most areas of the world, this rapid economic growth has been accompanied by large increases in energy consumption. China's coal-dominated energy structure has resulted in serious ecological and environmental problems. Exploiting renewable energy resources and introducing Renewables Portfolio Standard (RPS) are some of the most important approaches towards optimising and sustaining the energy structure of China. This paper discusses international experiences in the implementation of RPS policies and prospects for using these policies to encourage renewable energy development in China, establishes a concise definition of renewable resources, differentiating between the broad definition (which includes hydro over 25 MW in size) from the narrow definition (which limits the eligibility of hydro to below 25 MW in size), and quantitatively analyses the potential renewable energy target. The research shows that: (1) Under the narrow hydro definition the renewable energy target would be 5.1% and under the broad hydro definition it would be 18.4%. (2) Western China has contributed 90.2% of the total renewable electricity generation in the country (if big and medium hydropowers are not included). Including big and medium hydropower, the figure is 63.8%. (3) Eastern electricity companies can achieve their quota by buying Tradable Renewable Energy Certificates (TRCs or Green Certificates) and by exploiting renewable energy resources in Western China. The successful implementation of the RPS policy will achieve the goal of sharing the benefits and responsibilities of energy production between the different regions of China

    This study juxtaposes the major facts and arguments about nuclear energy and its potential role in establishing sustainable energy paths. The notion of sustainability has a strong normative character and can be interpreted in a variety of ways. Therefore, also the sustainability of energy supply technologies possesses a normative nature. This paper analyses what the major dimensions are that ought to be addressed when nuclear energy technology is compared, in sustainability terms, with its fossil-fuelled and renewable counterparts. It is assessed to what extent energy supply portfolios including nuclear energy are more, or less, sustainable in comparison to those that exclude this technology. It is indicated what this inventory of collected facts and opinions means for both policy and research regarding nuclear energy in the case of the Netherlands. 32 refs

    Full Text Available Sustainable energy development implies the need for the emerging potential energy sources which are not producing adverse effect to the environment. In this respect nuclear energy has gained the complimentary favor to be considered as the potential energy source without degradation of the environment. The sustainability evaluation of the nuclear energy systems has required the special attention to the criteria for the assessment of nuclear energy system before we can make firm justification of the sustainability of nuclear energy systems. In order to demonstrate the sustainability assessment of nuclear energy system this exercise has been devoted to the potential options of nuclear energy development, namely: short term option, medium term option, long term option and classical thermal system option. Criteria with following indicators are introduced in this analysis: nuclear indicator, economic indicator, environment indicator, social indicator... The Sustainability Index is used as the merit for the priority assessment among options under consideration.

  9. Portfolio Effects of Renewable Energies - Basics, Models, Exemplary Results

    The combination of sites and technologies to so-called renewable energy portfolios, which are being developed and implemented under the same financing umbrella, is currently the subject of intense discussion in the finance world. The resulting portfolio effect may allow the prediction of a higher return with the same risk or the same return with a lower risk - always in comparison with the investment in a single project. Models are currently being developed to analyse this subject and derive the portfolio effect. In particular, the effect of the spatial distribution, as well as the effects of using different technologies, suppliers and cost assumptions with different level of uncertainties, are of importance. Wind parks, photovoltaic, biomass, biogas and hydropower are being considered. The status of the model development and first results are being presented in the current paper. In a first example, the portfolio effect has been calculated and analysed using selected parameters for a wind energy portfolio of 39 sites distributed over Europe. Consequently it has been shown that the predicted yield, with the predetermined probabilities between 75 to 90%, is 3 - 8% higher than the sum of the yields for the individual wind parks using the same probabilities.

    This paper investigates energy resilience of countries by quantifying the supplier diversification of both direct and embodied energy import. In particular, we quantify two approaches to diversify a country's supplier portfolio: by lowering the dependency on each supplier (portfolio diversification) and by having embodied energy suppliers that are different from its direct energy suppliers (portfolio differentiation). We examine possibilities for strategic utilization of embodied energy trade to compensate for low diversity of direct energy trade for three types of fossil resources: coal, oil, and gas. We find that the diversity of embodied energy import is much greater than that of direct energy import. Of the three energy resources, coal enables countries to adopt portfolio diversification and portfolio differentiation more than gas and oil. Our results suggest embodied energy can be considered as a transfer of energy resources across national borders that can directly benefit from the diversity of the world energy production by “skipping” the limited diversity of the world energy export. - Highlights: • We quantify the diversity of countries’ supplier-portfolios of embodied energy. • The diversities of embodied energy import are greater than direct energy import. • Embodied energy is energy transfer that “skips” limited diversity of energy trade.

    None of the eight Millennium Development Goals (MDGs) adopted by the United Nations in 2000 directly addressed energy, although for nearly all of them - from eradicating poverty and hunger to improving education and health - progress has depended on greater access to modern energy. Thirteen years later, energy is being given more attention. The target date for the MDGs is 2015, and in 2012 the UN began deliberations to develop sustainable development goals to guide support for sustainable development beyond 2015. The Future We Want, the outcome document of the 2012 United Nations Conference on Sustainable Development (also known as Rio+20) gives energy a central role: ''We recognize the critical role that energy plays in the development process, as access to sustainable modern energy services contributes to poverty eradication, saves lives, improves health and helps provide for basic human needs''

  13. Do Sustainable Stocks Offer Diversification Benefits for Conventional Portfolios? An Empirical Analysis of Risk Spillovers and Dynamic Correlations

    Directory of Open Access Journals (Sweden)

    2017-10-01

    Full Text Available This paper explores the potential diversification benefits of socially responsible investments for conventional stock portfolios by examining the risk spillovers and dynamic correlations between conventional and sustainability stock indexes from a number of regions. We observe significant unidirectional volatility transmissions from conventional to sustainable equities, suggesting that the criteria applied for socially responsible investments do not necessarily shield these securities from common market shocks. While significant dynamic correlations are observed between sustainable and conventional stocks, particularly in Europe, the analysis of both in- and out-of-sample dynamic portfolios suggests that supplementing conventional stock portfolios with sustainable counterparts improves the risk/return profile of stock portfolios in all regions. The findings overall suggest that sustainable investments can indeed provide diversification gains for conventional stock portfolios globally.

  14. Sustainability-Oriented Financial Resource Allocation in a Project Portfolio through Multi-Criteria Decision-Making

    Directory of Open Access Journals (Sweden)

    2016-05-01

    Full Text Available Modern portfolio theory attempts to maximize the expected return of a portfolio for a given level of portfolio risk, or equivalently minimize risk for a given level of expected return. The reality, however, shows that, when selecting projects to a portfolio and allocating resources in the portfolio, an increasing number of organizations take into account other aspects as well. As a result of the sole purpose (risk-return, it offers only a partial solution for a sustainable organization. Existing project portfolio selection and resource allocation methods and models do not consider sustainability. Therefore, the aim of this article is to develop a sustainability-oriented model of financial resource allocation in a project portfolio by integrating a composite sustainability index of a project into Markowitz’s classical risk-return scheme (mean-variance model. The model was developed by applying multi-criteria decision-making methods. The practicability of the model was tested by an empirical study in a selected construction company. The proposed sustainability-oriented financial resource allocation model could be used in allocating financial resources in any type of business. The use of the model would not only help organisations to manage risk and achieve higher return but would also allow carrying out sustainable projects, thereby promoting greater environmental responsibility and giving more consideration to the wellbeing of future generations. Moreover, the model allows quantifying the impact of the integration of sustainability into financial resource allocation on the return of a portfolio.

    It is shown that present energy strategy requires adaptation of new criterions to be followed in the future energy system development. No doubt that there is a link between energy consumption and environment capacity reduction. This is an alarming sign, which recently has become the leading theme for our near and distant future. Modern engineering science has to be oriented to those areas which may directly assist in our future energy planning. In this respect, it is demanding need that our attention be oriented to the global aspect og the energy development. Modern technology will help to adopt essential principles of the sustainable energy development. With the appropriate renewable energy resources introduction in our energy future and with the increase of safety of nuclear energy, it will be possible to comply with the main principles to be adapted in the sustainable energy strategy. in order to promote the sustainable energy development the respective education system is required. It was recognized that the present energy education system can not meet future demand for the knowledge dissemination. It was shown that the potential option for the future education system is the distance learning with multimedia telematic system. (authors). 46 refs, 14 figs, 1 tab

    Full Text Available Mean-Variance Stochastic Goal Programming models (MV-SGP provide satisficing investment solutions in uncertain contexts. In this work, an MV-SGP model is proposed for portfolio selection which includes goals with regards to traditional and sustainable assets. The proposed approach is based on a two-step procedure. In the first step, sustainability and/or financial screens are applied to a set of assets (mutual funds previously evaluated with TOPSIS to determine the opportunity set. In a second step, satisficing portfolios of assets are obtained using a Goal Programming approach. Two different goals are considered. The first goal reflects only the purely financial side of the target while the second goal is referred to the sustainable side. Aversion to Risk Absolute (ARA coefficients are estimated and incorporated in our investment decision making approach using two different approaches.

    Renewable energy is considered by many policy-makers to contribute to achieving at least three major policy goals: the energy goal, the environmental goal, and the economic goal (3E goals). As an innovation-oriented island country with scarce natural resources, Taiwan announced the Sustainable Energy Policy Principles in 2008 that stated that Taiwan's renewable energy policy should accomplish the 3E goals. Several studies point out that specific renewable energy policy goals lead to specific renewable energy sources and technologies because each type of renewable energy has different features. In order to achieve the renewable energy policy goals, this research aims to examine how different policy goals lead to corresponding renewable energy sources. The relative importance of each goal is evaluated by using analytic hierarchy process (AHP). The weight of each policy goal is adjusted separately to construct policy scenarios by the sensitivity analysis. According to the results, non-pumped storage hydropower, wind energy, and solar energy are three sources that could meet the three policy goals at the same time. -- Highlights: →This study aims to propose a portfolio of renewable energy sources to achieve energy, environmental, and economic policy goals for Taiwan. →Non-pumped storage hydropower performs best to achieve energy and environmental goals. →Wind energy performs well to accomplish environmental goal. →Solar energy is the most preferred alternative to achieve economic goal. →The portfolio of non-pumped storage hydropower, wind energy, and solar energy can accomplish the three E policy goals at the same time.

    Considerations about 'post-Kyoto' targets and other ways to achieve the objectives of the Protocol are critical. Scientific evidence presented by the IPCC in its third assessment in 2002 clearly indicates the need not only to implement the Protocol, but also to agree on further emission reductions in the medium term in order to keep changes in the world's climate at a manageable level. UNEP's Energy Programme addresses the environmental consequences of energy production and use, such as global climate change and local air pollution. UNEP assists decision makers in government and the private sector to make better, more informed energy choices, which fully integrate environmental and social costs. Since UNEP is not an implementing organization, its role as facilitator is core. The majority of UNEP's energy activities link to mitigation - the reduction of greenhouse gas emissions - but these are generally accompanied by broader objectives related to energy and sustainable development. This includes climate change mitigation, but not as the sole objective since many of UNEP's partners in developing countries have more immediate development objectives. UNEP's main programmes are: The Solar and Wind Energy Resource Assessment (SWERA) project, that provides solar and wind resource data and geographic information assessment tools to public and private sector executives who are involved in energy market development; A new Global Environment Facility (GEF) funded programme aiming at promoting industrial energy efficiency through a cleaner production/environmental management system framework.

    2013-05-01

    Modern Portfolio Theory is a theory which was introduced by Markowitz, and which suggests the building of a portfolio with assets that have low or, in the best case, negative correlation. In times of financial crises, however, the positive diversification effect of a portfolio can fail when Traditional Assets are highly correlated. Therefore, many investors search for Alternative Asset classes, such as Renewable Energies, that tend to perform independently from capital market performance. 'Windfall Profit in Portfolio Diversification?' discusses the potential role of Renewable Energy investments in an institutional investor's portfolio by applying the main concepts from Modern Portfolio Theory. Thereby, the empirical analysis uses a unique data set from one of the largest institutional investors in the field of Renewable Energies, including several wind and solar parks. The study received the Science Award 2012 of the German Alternative Investments Association ('Bundesverband Alternative Investments e.V.').

    Sustainable development sets limits to our energy use within our economy. The main reason is the anthropologic greenhouse effect, limiting our fossil fuel consumption. It is important to emphasise that the greenhouse effect is not a political slogan but a well established scientific fact, with solid evidence brought into limelight about the phenomena over the last hundred years. But care should be taken about energy use even if we switch over to renewable s, for the sun radiation energy is not unlimited either. There is no danger that limitations on energy use would bring our life quality down, for we could produce all the needed goods and services with lower energy intensity, increasing the efficiency of our production processes and switching over from fossil fuels to renewable s. One should notice that it is impossible to solve the problems of excessive energy use only on the economical level. It's needed to change the public attitudes to ensure the proper support in combating the climate change and meeting the requirements of sustainable development

    Full Text Available The rapid population growth leads to greater daily demand for energy, causing nations to diversify their portfolios and seek new sources of energy, including renewable to provide more energy. In a universe with seriously exhausted natural resources, severe urbanization, climate change and conflicts that go beyond borders, the issue of overpopulation unquestionably causes worldwide debates and can generate a snowball effect for the global economy or human society. Population’s increase in the nearby future will have a central role in challenges such as: global warming, air and water contamination, increase in the level of poverty, food scarcity, deforestation, desertification, health problems and resource shortages. The transformation into a sustainable environmental model, situated in a post-carbon economy, will imply setting barriers to industrial progress (will have to be sustainable and environmental friendly and also to population growth (will have to follow a normal pace. But, the level on vulnerability and uncertainty in the evolution of energy has been threatened lately by major events that took place all around the world. Security of supply, new geopolitical perspectives and ecological and sustainability issues are yet again on the bleeding line. Therefore, the goal of this theoretical article is to give an overview of the current situation concerning the role of energy in ecological sustainability. It expresses routes in which humans and enterprises can act in order to contribute to ecologically sustainable development. The subject of how we live on a congested planet represents the most critical sustainability of all. We are witnessing our current risks and we can also envision our possible, and particularly desirable, future: a steady human population, living and protecting the nature and planet, having finite needs of goods, services, or energy, and maintaining a healthy Earth for us and the animals that also depend on it.

    All energy systems have adverse as well as beneficial impacts on the environment. They vary in quality, quantity, in time and in space. Environmentally sensitive energy management tries to minimize the adverse impacts in an equitable manner between different groups in the most cost-effective ways. Many of the enviornmental impacts of energy continue to be externalized. Consequently, these energy systems which can externalize their impacts more easily are favoured, while others remain relatively expensive. The lack of full integration of environmental factors into energy policy and planning is the overriding problem to be resolved before a transition towards sustainable energy futures can take place. The most pressing problem in the developing countries relates to the unsustainable and inefficient use of biomass resources, while in the industrialized countries, the major energy-environment problems arise out of the continued intensive use of fossil fuel resources. Both of these resource issues have their role to play in climate change. Although there has been considerable improvement in pollution control in a number of situations, most of the adverse impacts will undoubtedly increase in the future. Population growth will lead to increased demand, and there will also be greater use of lower grade fuels. Climate change and the crisis in the biomass resource base in the developing countries are the most critical energy-environment issues to be resolved in the immediate future. In both cases, international cooperation is an essential requirement for successful resolution. 26 refs.

    Full Text Available Abstract Sustainable procurement is a solution to integrate environmental and social considerations in all steps of procurement process, in order to reduce impacts on human health, environment, and human rights. Despite the existence of important works in this area, more studies for determining how the principles related to sustainable development can be integrated to procurement strategies are needed. This study presents a case study in a mining company to evaluate the elements that should be considered for the implementation of sustainability concept in the contracting of services through the application of a sustainability portfolio model. Results show that the contracts of the internal movement's category of the studied company fit as Strategic Commodity, which means that the items in this category have a risk in the strategic supply, because they need investments made by the buyer in the relationship with the supplier.

    Energy procurement is a necessity which needs a deep study of both the demand and the generation sources, referred to consumers territorial localization. The study presented in this paper extends and consolidate the Shimon Awerbuch’s study on portfolio theory applied to the energy planning, in order to define a broad generating mix which optimizes one or more objective functions defined for a determined contest. For this purpose the computation model was specialized in energy generation problem and extended with the addition of new cost-risk settings, like renewable energy availability, and Black–Litterman model, which extends Markowitz theory. Energy planning was then contextualized to the territory: the introduction of geographic and climatic features allows to plan energy infrastructures on both global and local (regional, provincial, municipal) scale. The result is an efficient decision making tool to drive the investment on typical energy policy assets. In general the tool allows to analyze several scenarios in support of renewable energy sources, environmental sustainability, costs and risks reduction. In this paper the model was applied to the energy generation in Italy, and the analysis was done: on the actual energy mix; assuming the use of nuclear technology; assuming the verisimilar improvement of several technologies in the future. -- Highlights: ► Extension and consolidation of Shimon Awerbuch’s studies. ► Introduction of aspects connected to realization and utilization of power plants. ► Application of the model on a national, provincial, municipal scale. ► Modification of Energy Portfolio based on subjective previsions (Black–Litterman).

The incomplete information non-cooperative game-theoretic method is utilized in which each generation company (GENCO) perceives strategies of other market participants in order to make a decision on its strategic generation capacity expansion. Sustainable generation incentives, carbon emission penalties, and fuel price forecast errors are considered in the strategic decisions. The market clearing process for energy and reserves is simulated by each GENCO for deriving generation expansion decisions. A merit criterion (i.e., the utility value) is proposed for a more realistic calculation of the expected payoff of a GENCO with sustainable energy resources. Finally, the impact of transmission constraints is investigated on the GENCO’s expansion planning decision. The case studies illustrate the effectiveness of the proposed method

    Starting from the basic definition of sustainable development and its four dimensions, the role of indicators for sustainable energy development is analysed. In particular, it is shown that important energy efficiency indicators belong in fact to energy supply efficiency, while the end-use energy efficiency could be more pertinently represented by energy intensity indicators. Furthermore, the negentropic effects of science and technology related sustainable energy scenarios are pointed out. Finally, the sustainable development is related to wisdom, interpreted as a sum of knowledge, morality and timing. (Author)

    Munoz, Jose Ignacio; Sanchez de la Nieta, Agustin A.; Contreras, Javier; Bernal-Agustin, Jose L.

    2009-01-01

    This article presents a model for investing in renewable energies in the framework of the Spanish electricity market in a way that risk is minimised for the investor while returns are maximised. The model outlined here is based on an economic model for calculating cash flows intended to obtain the internal rate of return (IRR) of the different energies being studied: wind, photovoltaic, mini hydro and thermo electrical. The IRRs obtained are considered the returns on investments, while their standard deviations are considered associated risks. In order to minimise risk, a comprehensive portfolio of investments is created that includes all of the available energies by means of a system of linear equations. The solution of the linear system is graphically checked using the efficient frontier method for the different financing options. Several case studies within the Renewable Energies Plan (PER is its Spanish abbreviation) that is in force in Spain in the period 2005-2010 are analysed in order to illustrate the method, as are other case studies using different types of financing, helping us to reach the pertinent conclusions.

  18. Energy efficiency as a resource in state portfolio standards: Lessons for more expansive policies

    International Nuclear Information System (INIS)

    Thoyre, Autumn

    2015-01-01

    In this paper, state electricity portfolio standards in the U.S. are analyzed to examine how energy efficiency is being created as a particular kind of resource through this type of climate change governance. Such policies can incentivize energy efficiency by requiring or encouraging electricity providers to meet a certain percentage of their demand through energy efficiency measures. North Carolina’s portfolio standard is used as an in-depth case study to identify factors that are then compared across all 36 states that include energy efficiency as part of a portfolio requirement or goal. The main finding of this study is that state portfolio standards tend to emphasize demand-side energy efficiency, or energy efficiency on the customer’s side of the electricity meter, and only rarely incentivize a full range of both demand-side and supply-side efficiency changes. As a result, the amount of energy efficiency and climate change mitigation benefits that are likely to result from this type of portfolio standard policy tool are limited. From this analysis, lessons are drawn out for crafting stronger portfolio standards that incentivize a wider range of efficiency changes across electricity networks. - Highlights: • Energy efficiency in 36 U.S. state portfolio standard policies was analyzed. • Such standards were found to incentivize mainly demand-side energy efficiency. • Supply-side energy efficiency was rarely incentivized by portfolio standards. • Such framings likely limit the carbon mitigation potential of these policies. • Recommendations are made for more expansive portfolio standard policies.

    State governments have taken the lead on U.S. energy and climate policy. It is not yet clear, however, whether state energy policy portfolios can generate results in a similar magnitude or manner to their presumed carbon mitigation potential. This article seeks to address this lack of policy evidence and contribute empirical insights on the carbon mitigation effects of state energy portfolios within the U.S. electricity sector. Using a dynamic, long-term electricity dispatch model with U.S. power plant, utility, and transmission and distribution data between 2010 and 2030, this analysis builds a series of state-level policy portfolio scenarios and performs a comparative scenario analysis. Results reveal that state policy portfolios have modest to minimal carbon mitigation effects in the long run if surrounding states do not adopt similar portfolios as well. The difference in decarbonization potential between isolated state policies and larger, more coordinated policy efforts is due in large part to carbon leakage, which is the export of carbon intensive fossil fuel-based electricity across state lines. Results also confirm that a carbon price of $50/metric ton CO 2 e can generate substantial carbon savings. Although both policy options - an energy policy portfolio or a carbon price - are effective at reducing carbon emissions in the present analysis, neither is as effective alone as when the two strategies are combined. - Research highlights: → Scenario modeling exercise to assess effectiveness of state energy policy portfolios. → Regional coordination has greater decarbonization potential than state policies. → Some states benefit more from regional policy coordination than others. → Emissions leakage attenuates the effect of isolated state policy portfolios. → Carbon price with coordinated energy portfolio has greatest decarbonization potential.

  3. 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

    The University of Ottawa (uOttawa) Faculty of Medicine in 2008 launched a revised undergraduate medical education (UGME) curriculum that was based on the seven CanMEDS roles (medical expert, communicator, collaborator, health advocate, manager, scholar, and professional) and added an eighth role of person to incorporate the dimension of mindfulness and personal well-being. In this article, the authors describe the development of an electronic Portfolio (ePortfolio) program that enables uOttawa medical students to document their activities and to demonstrate their development of competence in each of the eight roles. The ePortfolio program supports reflective practice, an important component of professional competence, and provides a means for addressing the "hidden curriculum." It is bilingual, mandatory, and spans the four years of UGME. It includes both an online component for students to document their personal development and for student-coach dialogue, as well as twice-yearly, small-group meetings in which students engage in reflective discussions and learn to give and receive feedback.The authors reflect on the challenges they faced in the development and implementation of the ePortfolio program and share the lessons they have learned along the way to a successful and sustainable program. These lessons include switching from a complex information technology system to a user-friendly, Web-based blog platform; rethinking orientation sessions to ensure that faculty and students understand the value of the ePortfolio program; soliciting student input to improve the program and increase student buy-in; and providing faculty development opportunities and recognition.

    Full text: Neutron scattering is essential for the study of sustainable energy materials, including the areas of hydrogen research (such as its separation, storage, and use in fuel-cells) and energy transport (such as fuel-cell and battery materials). Researchers at the Bragg Institute address critical questions in sustainable energy research, with researchers providing a source of expertise for external collaborators, specialist analysis equipment, and acting as a point of contact for the study of sustainable energy materials using neutron scattering. Some recent examples of sustainable energy materials research using neutron scattering will be presented. These examples include the storage of energy, in the form of hydrogen through a study of its location in and interaction with new porous hydrogen storage materials [1-3] and in battery materials through in-situ studies of structure during charge-discharge cycling, and use of energy in fuel cells by studying proton diffusion through fuel cell membranes.

    Integration of New Member States to the European Union has created a new situation in the frame of implementation of the Lisbon strategy and EU Sustainable Development. The closure of Ignalina NPP is the biggest challenge to the energy sector development of the Baltic States. The Baltic States have quite limited own energy resources and in the Accession agreement with the EU Lithuania, Latvia and Estonia have verified their targets to increase the share of electricity produced from renewable energy sources (RES-E) by the year 2010. A wider use of renewable energy and increase of energy efficiency can make a valuable contribution to meeting the targets of sustainable development. The article presents a detailed overview of the present policies and measures implemented in the Baltic States, aiming to support the use of RES and the increase of energy efficiency. The review of possibilities to use the EU Structural Funds (SF) for the implementation of sustainable energy projects in the Baltic States was performed.The use of regional social-economic-environmental indicators is the main key to integrate sustainable energy development at the program deployment level. The indicators to be used should describe the contribution of energy programs to the sustainable development, medium- and long-term trends and inter-relationship between them and the typical energy indicators (saved toe, improved energy efficiency, percentage of RES). Municipalities may play a considerable role by promoting sustainable energy since local authorities are fulfilling their functions in the energy sector via a number of roles. The Netherlands' example shows that municipalities may act as facilitators by implementing national environmental policy and increasing energy efficiency in an integral part of these activities. The guidelines for Lithuanian local sustainable energy development using the SF co-financing have been presented

  15. Energy sustainability: consumption, efficiency, and ...

    Science.gov (United States)

    One of the critical challenges in achieving sustainability is finding a way to meet the energy consumption needs of a growing population in the face of increasing economic prosperity and finite resources. According to ecological footprint computations, the global resource consumption began exceeding planetary supply in 1977 and by 2030, global energy demand, population, and gross domestic product are projected to greatly increase over 1977 levels. With the aim of finding sustainable energy solutions, we present a simple yet rigorous procedure for assessing and counterbalancing the relationship between energy demand, environmental impact, population, GDP, and energy efficiency. Our analyses indicated that infeasible increases in energy efficiency (over 100 %) would be required by 2030 to return to 1977 environmental impact levels and annual reductions (2 and 3 %) in energy demand resulted in physical, yet impractical requirements; hence, a combination of policy and technology approaches is needed to tackle this critical challenge. This work emphasizes the difficulty in moving toward energy sustainability and helps to frame possible solutions useful for policy and management. Based on projected energy consumption, environmental impact, human population, gross domestic product (GDP), and energy efficiency, for this study, we explore the increase in energy-use efficiency and the decrease in energy use intensity required to achieve sustainable environmental impact le

    Energy is an essential factor in overall efforts to achieve sustainable development. Countries striving to this end are seeking to reassess their energy systems with a view toward planning energy programmes and strategies in line with sustainable development goals and objectives. This paper summarizes the outcome of an international partnership initiative on indicators for sustainable energy development that aims to provide an analytical tool for assessing current energy production and use patterns at a national level. The proposed set of energy indicators represents a first step of a consensus reached on this subject by five international agencies-two from the United Nations system (the Department of Economic and Social Affairs and the International Atomic Energy Agency), two from the European Union (Eurostat and the European Environment Agency) and one from the Organization for Economic Cooperation and Development (the International Energy Agency). Energy and environmental experts including statisticians, analysts, policy makers and academics have started to implement general guidelines and methodologies in the development of national energy indicators for use in their efforts to monitor the effects of energy policies on the social, economic and environmental dimensions of sustainable development

    More than a dozen energy experts convened in Houston, Texas, on February 13, 2009, for the first in a series of four regionally-based energy summits being held by the Council on Competitiveness. The Southern Energy Summit was hosted by Marathon Oil Corporation, and participants explored the public policy, business and technological challenges to increasing the diversity and sustainability of U.S. energy supplies. There was strong consensus that no single form of energy can satisfy the projected doubling, if not tripling, of demand by the year 2050 while also meeting pressing environmental challenges, including climate change. Innovative technology such as carbon capture and storage, new mitigation techniques and alternative forms of energy must all be brought to bear. However, unlike breakthroughs in information technology, advancing broad-based energy innovation requires an enormous scale that must be factored into any equation that represents an energy solution. Further, the time frame for developing alternative forms of energy is much longer than many believe and is not understood by the general public, whose support for sustainability is critical. Some panelists estimated that it will take more than 50 years to achieve the vision of an energy system that is locally tailored and has tremendous diversity in generation. A long-term commitment to energy sustainability may also require some game-changing strategies that calm volatile energy markets and avoid political cycles. Taking a page from U.S. economic history, one panelist suggested the creation of an independent Federal Energy Reserve Board not unlike the Federal Reserve. The board would be independent and influence national decisions on energy supply, technology, infrastructure and the nation's carbon footprint to better calm the volatile energy market. Public-private efforts are critical. Energy sustainability will require partnerships with the federal government, such as the U.S. Department of Energy

    A political agreement from 2005 stated that an evaluation of the entire Danish energy efficiency policy portfolio must be carried out before the end of 2008, with the aim to assess the following: (1) Is the policy portfolio sufficient to meet the energy efficiency targets? (2) Do the policies enable the national goals to be met in a cost-effective manner? (3) Is the overall design of the policy portfolio appropriate? The evaluation gave recommendations on how to improve and develop the portfolio, mainly using cost-effectiveness as criteria. The evaluation was completed in December 2008, and this paper presents the main findings and the subsequent impact on Danish policy. A key lesson learned is the importance of including all energy efficiency policies in the evaluation. Examining the entire portfolio of policies (as opposed to only selected policies) gave way to findings that would otherwise not have been captured. With its broad perspective, the evaluation found that the policy instruments prioritised the commercial and industrial sectors less than the household and public sectors. The recommendations made by the authors contributed to the implementation of new taxes for the commercial and industrial sectors together with the reform of the Electricity Saving Trust to a Centre for Energy Savings charged with energy savings within all sectors, except transport - both which have been important steps towards a more cost-effective solution.

    This book starts out with the optimistic perspective that modern cities can indeed play a strategic role in the necessary pathway to sustainable development, with particular emphasis on the opportunities offered by local energy and environmental initiatives. Our study aims to demonstrate that an urban sustainability policy has many socio-economic benefits, while it also seeks to identify the critical success and failure factors of sustainable city innovations. After a comprehensive review of various opportunities and experiences, attention is focused particularly on renewable energy resources which may offer new potential for the active involvement of local authorities. The study also highlights major impediments regarding the adoption and implementation of renewable energies, in particular, the development of advanced energy-environmental technology in a world dominated by natural (public) monopolies and/or monopolistic competition elements. In this context both theoretical and empirical elements are discussed, as well as institutional aspects. The theory and methodology is tested by a thorough empirical investigation into local renewable energy initiatives in three European countries, viz. Greece, Italy and The Netherlands. Based on an extensive data base, various statistical models are estimated in order to identify the key elements and major driving forces of sustainable development at the city level. And finally, the study is concluded with a long list of applicable and operational policy guidelines for urban sustainability. These lessons are largely based on meta-analytic comparative studies of the various initiatives investigated. (orig.)

    A huge increase in energy use is expected in the coming decades – see the IEA’s ‘business as usual’/reference scenario below. While developed countries could use less energy, a large increase is needed to lift billions out of poverty, including over 25% of the world’s population who still lack electricity. Meeting demand in an environmentally responsible manner will be a huge challenge. The World Bank estimates that coal pollution leads to 300,000 deaths in China each year, while smoke from cooking and heating with biomass kills 1.3 million world-wide – more than malaria. The IEA’s alternative scenario requires a smaller increase in energy use than the reference scenario and is also less carbon intensive, but it still implies that CO2 emissions will increase 30% by 2030 (compared to 55% in the reference scenario). Frighteningly, implementing the alternative scenario faces “formidable hurdles” according to the IEA, despite the fact that it would yield financial savings for consumers that...

Nanomaterials have the potential to change the way we generate, deliver and use energy. Hydrogen cells are used in auto industry as a viable power source. Compressed hydrogen tanks are used to supply Hydrogen, and Oxygen is used from the air directly. There is no pollution caused by hydrogen fuel cell autos since the only emission is water. Organic dyes (dye sensitizers), which are sensitive to light, can absorb a broader range of the sun's spectrum. A dye-sensitized solar cell has three primary parts. On top is a transparent anode made of fluoride-doped tin dioxide (SnO/sub 2/: F) deposited on the back typically of a glass plate. On the back of this conductive plate is a thin layer of titanium dioxide (TiO/sub 2/), which forms into a highly nanoporous structure with an extremely large surface-area. After soaking the film in the dye solution, a thin layer of the dye is left covalently bonded to the surface of the TiO/sub 2/ . Computational material science and nanoscience can play many critical roles in renewable energy research. These include: finding the right materials for hydrogen storage; finding the most reliable and efficient catalyst for water dissociation in hydrogen production; finding a cheap, environmentally benign, and stable material for efficient solar cell applications; and understanding the photo-electron process in a nanosystem, and hence helping design efficient nanostructure solar cells.

    Under the Clean Energy Works (CEW) program, Craft3 developed a loan product that widened access to financing for homeowners, offered long term funding, and collected repayments through the customer?s utility bill. The program?s success led Craft3 to pursue the sale of the loan portfolio to both mitigate its own risks and replenish funds for lending. This sale breaks new ground for energy efficiency finance and is notable as it was completed even with many novel program design elements. It replenished Craft3?s program capital and uncovered some valuable lessons that may facilitate future transactions. However, the lack of data history and the unproven nature of the loan portfolio meant that Craft3 had to limit the risk of losses to Self-Help, the purchaser of the portfolio. It remains to be seen whether this experience will pave the way for more sales of on-bill energy efficiency loan portfolios. This case study illustrates how certain program design decisions can sometimes both facilitate programmatic objectives and possibly present challenges for the sale of a portfolio of energy efficiency loans.

    Global potable water demand is expected to grow, particularly in areas where freshwater supplies are limited. Production and supply of potable water requires significant amounts of energy, which is currently being derived from nonrenewable fossil fuels. Since energy production from fossil fuels also requires water, current practice of potable water supply powered by fossil fuel derived energy is not a sustainable approach. In this paper, a sustainable phase-change desalination process is presented that is driven solely by solar energy without any reliance on grid power. This process exploits natural gravity and barometric pressure head to maintain near vacuum conditions in an evaporation chamber. Because of the vacuum conditions, evaporation occurs at near ambient temperature, with minimal thermal energy input for phase change. This configuration enables the process to be driven by low-grade heat sources such as solar energy or waste heat streams. Results of theoretical analysis and prototype scale experimental studies conducted to evaluate and demonstrate the feasibility of operating the process using solar energy are presented. Predictions made by the theoretical model correlated well with measured performance data with r 2 > 0.94. Test results showed that, using direct solar energy alone, the system could produce up to 7.5 L/day of freshwater per m 2 of evaporator area. With the addition of a photovoltaic panel area of 6 m 2 , the system could produce up to 12 L/day of freshwater per m 2 of evaporator area, at efficiencies ranging from 65% to 90%. Average specific energy need of this process is 2930 kJ/kg of freshwater, all of which can be derived from solar energy, making it a sustainable and clean process.

  2. Energy for a sustainable world

    International Nuclear Information System (INIS)

    Goldemberg, Jose; Reddy, A.K.N.; Williams, R.H.

    1988-01-01

    The book is devoted to the problem of energy planning for a sustainable world. The principal objective of the conventional approach to energy problem is economic growth and consequently the primary goal of conventional energy planning is to make energy supply expansion possible. This conventional approach is aggravating societal inequalities, environmental and security problems, and eroding self-reliance. On the other hand societal goals in energy planning should be equity, economic efficiency, environmental harmony, long-term viability, self-reliance and peace. These goals are relevant to both developing and industrialised countries. These goals should, therefore, be incorporated in a normative approach to energy planning. This can be done by focussing on end-uses of energy and the services which energy performs. In the first chapter, the relation of global energy problem with other major global problems such as North-South disparities, environmental degradation, climate change, population explosion and nuclear weapons is brought out. The energy strategies for industrialized countries and for developing countries are examined in chapters 2 and 3 respectively. The focus in both chapters is on end-uses of enegy, management of energy demand and exploitation of synergisms. In chapter 4, rough estimates of global energy demand are given and an illustrative energy scenario compatible with societal goals is described. In chapter 5, the policies necessary to implement end-use-oriented energy strategies are outlined. These policies relate to market mechanisms, administrative allocation of energy carriers, regulation and taxes. In the concluding chapter 6, the political feasibility of implementing the kind of energy future envisaged is discussed. The main finding of the authors is that it is possible to formulate energy strategies compatible with the solution of major global problems referred to in chapter 1 with about the same level of global energy use as today.

    This following project demonstrates an interdisciplinary method of teaching Sustainability, Energy and Green Economics. It is shown that an interdisciplinary approach to introduce students to the foundations of sustainability strongly connects education with real world applications, and highlights the growing influence of sustainable practices on the world at large. The authors will present results from the interdisciplinary course "Sustainability, Energy and Green Economy" taught at the Center of Sustainable Energy, Bronx Community College, City University of New York (CSE-BCC-CUNY) by faculty from Physics, Chemistry, Biology. The course curriculum covers the relationship of humans within their environment, the facts of climate change, an analysis of the current global energy portfolio, the burgeoning renewable energy sector, and connections between consumption and quality of life. The students are exposed to empirical data and asked to evaluate trends to ascertain the future energy and resource demands of a growing global population. The students are lead through an estimation of their own carbon footprint. Emphasis is made on the concept of `Life Cycle Analysis' and how such analyses can be used to create market value and a "green product". The interdisciplinary approach to teach students on how the principles of sustainability are building the green economy and how to build a successful career within today's workforce encourages students to apply the critical lens of sustainability to all aspects of their personal lives, as well as local, regional and global economies. The authors will present data collected by students to formulate and articulate a hypothesis specifically related to the sustainability of societal and economic market trends.

    2009-01-01

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

  5. Sustainability, energy technologies, and ethics

    Energy Technology Data Exchange (ETDEWEB)

    1999-01-01

    A study of the economic, social-political, and environmental consequences of using renewable energy technologies (RETs, e.g., photovoltaics, wind, solar thermal, biofuels) as compared to those of conventional energy technologies (CETs e.g., oil, coal, gas) would show that RETs are singularly consistent with a whole ethic that is implicit in the concept of sustainability. This paper argues for sustainability as an ethical, as well as a pragmatic, imperative and for RETs as an integral part of this imperative. It brings to the fore some of the specific current economic, political, and environmental assumptions and practices that are inconsistent with both sustainability and with a rapid deployment of RETs. Reflecting an emerging planetary awareness and a pressing need to come to terms with intra- and intergenerational equity, the concept of sustainability explicitly entails the right of future generations to the same opportunity of access to a healthy ecological future and the finite endowment of the Earth`s resources as that of the present generation.

  7. Wind Energy for Sustainable Development

    2009-01-01

    The growing demand in energy and concern about depleting natural resources and global warming has led states worldwide to consider alternatives to the use of fossil fuel for energy production. Several countries especially in Europe have already increased their renewable energy share 6-10%, expected to increase to 20% by the year 2020. For Egypt excellent resources of wind and solar energy exist. The article discusses perspectives of wind energy in Egypt with projections to generate ∼ 3.5 GWe by 2022, representing ∼ 9% of the total installed power at that time (40.2 GW). Total renewable (hydro + wind + solar) are expected to provide ∼ 7.4 GWe by 2022 representing ∼ 19% of the total installed power. Such a share would reduce dependence on depleting oil and gas resources, and hence improve country's sustainable development

  8. CO_2 volatility impact on energy portfolio choice: A fully stochastic LCOE theory analysis

    International Nuclear Information System (INIS)

    Lucheroni, Carlo; Mari, Carlo

    2017-01-01

    Highlights: • Stochastic LCOE theory is an extension of the levelized cost of electricity analysis. • The fully stochastic analysis include stochastic processes for fossil fuels prices and CO_2 prices. • The nuclear asset is risky through uncertainty about construction times and it is used as a hedge. • Volatility of CO_2 prices has a strong influence on CO_2 emissions reduction. - Abstract: Market based pricing of CO_2 was designed to control CO_2 emissions by means of the price level, since high CO_2 price levels discourage emissions. In this paper, it will be shown that the level of uncertainty on CO_2 market prices, i.e. the volatility of CO_2 prices itself, has a strong influence not only on generation portfolio risk management but also on CO_2 emissions abatement. A reduction of emissions can be obtained when rational power generation capacity investors decide that the capacity expansion cost risk induced jointly by CO_2 volatility and fossil fuels prices volatility can be efficiently hedged adding to otherwise fossil fuel portfolios some nuclear power as a carbon free asset. This intriguing effect will be discussed using a recently introduced economic analysis tool, called stochastic LCOE theory. The stochastic LCOE theory used here was designed to investigate diversification effects on energy portfolios. In previous papers this theory was used to study diversification effects on portfolios composed of carbon risky fossil technologies and a carbon risk-free nuclear technology in a risk-reward trade-off frame. In this paper the stochastic LCOE theory will be extended to include uncertainty about nuclear power plant construction times, i.e. considering nuclear risky as well, this being the main uncertainty source of financial risk in nuclear technology. Two measures of risk will be used, standard deviation and CVaR deviation, to derive efficient frontiers for generation portfolios. Frontier portfolios will be analyzed in their implications on emissions

  9. A System of Systems (SoS) Approach to Sustainable Energy Planning

    2015-04-01

    The general policy of mandating fossil fuel replacement with "green" energies may not be as effective and environmental-friendly as perceived, due to the secondary impacts of renewable energies on different natural resources. An integrated systems analysis framework is essential to developing sustainable energy supply systems with minimal unintended impacts on valuable natural resources such as water, climate, and ecosystem. This presentation discusses how a system of systems (SoS) framework can be developed to quantitatively evaluate the desirability of different energy supply alternatives with respect to different sustainability criteria under uncertainty. Relative Aggregate Footprint (RAF) scores of a range of renewable and nonrenewable energy alternatives are determined using their performance values under four sustainability criteria, namely carbon footprint, water footprint, land footprint, and cost of energy production. Our results suggest that despite their lower emissions, some renewable energy sources are less promising than non-renewable energy sources from a SoS perspective that considers the trade-offs between carbon footprint of energies and their effects on water, ecosystem, and economic resources. A new framework based on the Modern Portfolio Theory (MPT) is also proposed for analyzing the overall sustainability of different energy mixes for different risk of return levels with respect to the trade-offs involved. It is discussed how the proposed finance-based sustainability evaluation method can help policy makers maximize the energy portfolio's expected sustainability for a given amount of portfolio risk, or equivalently minimize risk for a given level of expected sustainability level, by revising the energy mix.

    Finland tops the statistics for the industrialised world in the utilisation of bioenergy. In 1995 bioenergy, including peat-fired heat and power, accounted for 20 % of the total energy consumption. The declared goal of the government is to increase the use of bioenergy by not less than 25 % (1.5 million toe by the year 2005). Research and development plays a crucial role in the promotion of the expanded use of bioenergy in Finland. The aim is to identify and develop technologies for establishing and sustaining economically, environmentally and socially viable bioenergy niches in the energy system

  11. Power sector investment risk and renewable energy: A Japanese case study using portfolio risk optimization method

    Bhattacharya, Anindya; Kojima, Satoshi

    2012-01-01

    The conventional pricing mechanism used for electricity systematically hides huge investment risks which are embedded in the overall cost of production. Although consumers are often unaware of these risks, they present a large financial burden on the economy. This study applies the portfolio optimization concepts from the field of finance to demonstrate the scope of greater utilization of renewable energies (RE) while reducing the embedded investment risk in the conventional electricity sector and its related financial burden. This study demonstrates that RE investment can compensate for the risks associated with the total input costs; such costs being external volatilities of fossil fuel prices, capital costs, operating and maintenance costs and the carbon costs. By means of example, this case study shows that Japan could in theory obtain up to 9% of its electricity supply from green sources, as compared to the present 1.37%, based on the utilization of a portfolio risk-analysis evaluation. Explicit comparison of the monetary values of the investment risks of conventional and renewable energy sources shows that renewable energies have high market competitiveness. The study concludes with a recommendation that, as a business objective, investors would benefit by focusing on electricity supply portfolio risk minimization instead of cost. This could also inherently increase the supply of renewable energy in the market. - Research highlights: ►Energy sector investors should not be bothered only about the absolute cost figures of the input factors like fossil fuels but should also be careful about the fluctuation of their costs while making the investment decisions. ►Inclusion of renewable energy in the investment portfolio can increase the cost apparently but can reduce the risk hedging costs, too. ►International carbon price may not be a good factor to encourage renewable energy investment in the market.

    2010-01-01

    Commercialization efforts to diffuse sustainable energy technologies (SETs) have so far remained as the biggest challenge in the field of renewable energy and energy efficiency. Limited success of diffusion through government driven pathways urges the need for market based approaches. This paper reviews the existing state of commercialization of SETs in the backdrop of the basic theory of technology diffusion. The different SETs in India are positioned in the technology diffusion map to reflect their slow state of commercialization. The dynamics of SET market is analysed to identify the issues, barriers and stakeholders in the process of SET commercialization. By upgrading the 'potential adopters' to 'techno-entrepreneurs', the study presents the mechanisms for adopting a private sector driven 'business model' approach for successful diffusion of SETs. This is expected to integrate the processes of market transformation and entrepreneurship development with innovative regulatory, marketing, financing, incentive and delivery mechanisms leading to SET commercialization.

    International Nuclear Information System (INIS)

    Mahone, A.; Woo, C.K.; Williams, J.; Horowitz, I.

    2009-01-01

    Renewable portfolio standards (RPSs) and mandates to invest in cost-effective energy efficiency (EE) are increasingly popular policy tools to combat climate change and dependence on fossil fuels. These supply-side and demand-side policies, however, are often uncoordinated. Using California as a case in point, this paper demonstrates that states could improve resource allocation if these two policies were coordinated by incorporating renewable-energy procurement cost into the cost-effectiveness determination for EE investment. In particular, if renewable energy is relatively expensive when compared to conventional energy, increasing the RPS target raises the cost-effective level of EE investment

    This report discusses the potential for reducing the use of energy and quantifies the environmental disadvantages and estimated environmental costs of various energy carriers in Norway. The MARKAL model is used to work out three scenarios for a more sustainable use of energy. It is found that the environmental impact of NOx emissions are much greater than that of sulfur emissions. The damage caused by CO2 and NOx are of the same order of magnitude. The studies indicate that if the damage to the environment is internalized into the energy system, then it will lead to increased use of gas in the industry and transport sectors. The results are sensitive with respect to the cost development for the cleaning technology of conventional energy carriers and for storage and transport of gas. Internalizing the external costs is not enough to eliminate the environmental damage, at least not as this is valued today and with the technology supposed to be available for the next 30-40 years.

    level of building performance (BP), which can be defined as indoor environmental quality (IEQ), energy efficiency (EE) and cost efficiency (CE). circle Indoor environmental quality is the perceived condition of comfort that building occupants experience due to the physical and psychological conditions to which they are exposed by their surroundings. The main physical parameters affecting IEQ are air speed, temperature, relative humidity and quality. circle Energy efficiency is related to the provision of the desired environmental conditions while consuming the minimal quantity of energy. circle Cost efficiency is the financial expenditure on energy relative to the level of environmental comfort and productivity that the building occupants attained. The overall cost efficiency can be improved by improving the indoor environmental quality and the energy efficiency of a building. This article discusses the potential for such integrated systems in the stationary and portable power market in response to the critical need for a cleaner energy technology. Anticipated patterns of future energy use and consequent environmental impacts (acid precipitation, ozone depletion and the greenhouse effect or global warming) are comprehensively discussed in this paper. Throughout the theme several issues relating to renewable energies, environment and sustainable development are examined from both current and future perspectives. (author)

    A holistic perspective of various energy stakeholders regarding the Strengths, Weaknesses, Opportunities and Threats (SWOTs) of the energy sector in Macedonia is utilized as baseline to diagnose the current state and to sketch future action lines towards sustainable energy development. The resulting SWOT analyses pointed to the progressive adoption of European Union (EU) standards in energy policy and regulation as the most important achievement in the energy sector. The most important problems the national energy sector faces are scarce domestic resources and unfavorable energy mix, low electricity prices, a high degree of inefficiency in energy production and use, as well as insufficient institutional and human capacities. The formulated portfolio of actions towards enabling sustainable energy development urges the adoption of a comprehensive energy strategy built upon sustainability principles, intensified utilization of the natural gas, economic prices of electricity, structural changes in industry, promotion of energy efficiency and renewables, including Clean Development Mechanism (CDM) projects, enforcement of EU environmental standards and meeting the environmental requirements, as well as institutional and human capacity building.

    The diverse nature and uncertain potential of the energy technologies that are or may be available to mitigate greenhouse gas emissions pose a challenge to policymakers trying to invest public funds in an optimal R and D portfolio. This paper discusses two analytical approaches to this challenge used to inform funding decisions related to the U.S. Department of Energy (DOE) applied energy R and D portfolio. The two approaches are distinguished by the constraints under which they were conducted: the need to provide an end-to-end portfolio analysis as input to internal DOE budgeting processes, but with limited time and subject to institutional constraints regarding important issues such as expert judgment. Because of these constraints, neither approach should be viewed as an attempt to push forward the state of the art in portfolio analysis in the abstract. Instead, they are an attempt to use more stylized, heuristic methods that can provide first-order insights in the DOE institutional context. Both approaches make use of advanced technology scenarios implemented in an integrated assessment modeling framework and then apply expert judgment regarding the likelihood of achieving associated R and D and commercialization goals. The approaches differ in the granularity of the scenarios used and in the definition of the benefits of technological advance: in one approach the benefits are defined as the cumulative emission reduction attributable to a particular technology; in the other approach benefits are defined as the cumulative cost reduction. In both approaches a return on investment (ROI) criterion is established based on benefits divided by federal R and D investment. The ROI is then used to build a first-order approximation of an optimal applied energy R and D investment portfolio. Although these methodologies have been used to inform an actual budget request, the results reflect only one input among many used in budget formulation. The results are therefore not

    The Dutch Ministry of Economic Affairs, Agriculture and Innovation asked ECN several questions about the development of a supplier's obligation. These questions addressed the volume of the certificates market. The questions are worded as follows by ECN: What is a realistic level to be set for the obligation for sustainable energy or for renewable electricity (in percentage of delivered electricity or TWh/year)? How far into the future should these obligations minimally be set? Is it desirable to limit the certificate issuance time to for example the economic life of an installation? This memo addresses the questions, knowing that the entire policy development process will still take considerable time. At the time of publication of this memo, large uncertainties still existed about the eventual shaping of future policy. [nl

    Renewable energy generation is expected to continue to increase globally due to renewable energy targets and obligations to reduce greenhouse gas emissions. Some renewable energy sources are variable power sources, for example wind, wave and solar. Energy storage technologies can manage the issues associated with variable renewable generation and align non-dispatchable renewable energy generation with load demands. Energy storage technologies can play different roles in each of the step of the electric power supply chain. Moreover, large scale energy storage systems can act as renewable energy integrators by smoothing the variability. Compressed air energy storage is one such technology. This paper examines the impacts of a compressed air energy storage facility in a pool based wholesale electricity market in a power system with a large renewable energy portfolio

  6. The environmental and cost implications of solar energy preferences in Renewable Portfolio Standards

    International Nuclear Information System (INIS)

    2015-01-01

    Many state-level Renewable Portfolio Standards (RPS) include preferences for solar generation, with goals of increasing the generation diversity, reducing solar costs, and encouraging local solar industries. Depending on their policy design, these preferences can impact the RPS program costs and emissions reduction. This study evaluates the impact of these policies on costs and emissions, coupling an economic dispatch model with optimized renewable site selection. Three policy designs of an increased RPS in Michigan are investigated: (1) 20% Solar Carve-Out, (2) 5% Distributed Generation Solar Carve-Out, and (3) 3× Solar Multiplier. The 20% Solar Carve-Out scenario was found to increase RPS costs 28%, while the 5% Distributed Generation Solar Carve-Out increased costs by 34%. Both of these solar preferences had minimal impact on total emissions. The 3× Solar Multiplier decreases total RPS program costs by 39%, but adds less than half of the total renewable generation of the other cases, significantly increasing emissions of CO_2, NO_x, and SO_2 relative to an RPS without the solar credit multiplier. Sensitivity analysis of the installed cost of solar and the natural gas price finds small changes in the results of the Carve-Out cases, with a larger impact on the 3× Solar Multiplier. - Highlights: • A unit commitment and economic dispatch model is used to assess Renewable Portfolio Standard expansion. • The impact of solar carve-outs and multipliers on costs and benefits of Renewable Portfolio Standards are analyzed. • Solar carve-outs increase costs and have minimal impact on emissions. • The solar multiplier decreases total renewable energy expansion. • The multiplier decreases the emissions reduction potential of the Renewable Portfolio Standard.

  8. Green energy strategies for sustainable development

    International Nuclear Information System (INIS)

    Midilli, Adnan; Dincer, Ibrahim; Ay, Murat

    2006-01-01

    In this study we propose some green energy strategies for sustainable development. In this regard, seven green energy strategies are taken into consideration to determine the sectoral, technological, and application impact ratios. Based on these ratios, we derive a new parameter as the green energy impact ratio. In addition, the green energy-based sustainability ratio is obtained by depending upon the green energy impact ratio, and the green energy utilization ratio that is calculated using actual energy data taken from literature. In order to verify these parameters, three cases are considered. Consequently, it can be considered that the sectoral impact ratio is more important and should be kept constant as much as possible in a green energy policy implementation. Moreover, the green energy-based sustainability ratio increases with an increase of technological, sectoral, and application impact ratios. This means that all negative effects on the industrial, technological, sectoral and social developments partially and/or completely decrease throughout the transition and utilization to and of green energy and technologies when possible sustainable energy strategies are preferred and applied. Thus, the sustainable energy strategies can make an important contribution to the economies of the countries where green energy (e.g., wind, solar, tidal, biomass) is abundantly produced. Therefore, the investment in green energy supply and progress should be encouraged by governments and other authorities for a green energy replacement of fossil fuels for more environmentally benign and sustainable future

  9. Impacts of a renewable portfolio generation standard on US energy markets

    International Nuclear Information System (INIS)

    Kydes, Andy S.

    2007-01-01

    This paper analyzes the impacts of imposing a Federal 20 percent non-hydropower renewable generation portfolio standard (RPS) on US energy markets by 2020. The US currently has no RPS requirement although some state RPS regulations have been adopted but not uniformly enforced (see http://www.eia.doe.gov/oiaf/analysispaper/rps/index.html for a recent summary on RPSs in the US). The renewable portfolio standard (RPS) requires that 20 percent of the power sold must come from qualifying renewable facilities. The analysis of the 20 percent RPS was developed by using the December 2001 version of the National Energy Modeling System (NEMS) of the Energy Information Administration (EIA) and the assumptions and results of the Annual Energy Outlook 2002 (AEO2002) reference case. A policy that requires a 20 percent non-hydro-electric RPS by 2020 appears to be effective in promoting the adoption of renewable generation technologies while also reducing emissions of nitrogen oxides by 6 percent, mercury by 4 percent and carbon dioxide by about 16.5 percent relative to the reference case in 2020. Electricity prices are expected to rise about 3 percent while the cost to the electric power industry could rise between 35 and 60 billion dollars (in year 2000 dollars in net present value terms)

    To sustain decent environmental conditions, it is essential to contain the emission of greenhouse gases. to a great extent, this can be achieved by reducing the almost exclusive dependence of fossil fuels for producing electricity and by championing nuclear energy and the renewable, which in the end are the least contaminating. Specifically, operation of the European nuclear fleet avoids the yearly emission of 700 million tons of CO 2 to the atmosphere. The need to combat climate change is very serious and increasingly imminent, especially if we remember that the World Health Organization has said that climate change could eventually cause 300,000 deaths. The different social players are aware of the problem. In fact, the European Union's Cabinet of Ministers approved the post-kyoto Environmental Strategy, which underlines the need to reduce CO e missions by 80% by the year 2050. It seems obvious that, in the long run, technological research and development will be fundamental pieces in the battle against environmental change and in the effort to one day provide 2,000 million people with access to electricity.

    Energy systems, which include energy production, conversion, transportation, distribution and utilization, are key infrastructures in modern society. Interactions among energy systems are generally studied under the framework of energy trade. Although such studies have generated important insights, there are limitations. Many distant interactions (e.g. those due to the Fukushima nuclear crisis) are not in the form of trade, but affect energy sustainability. Even when distant interactions are related to energy trade, they are not systematically analyzed. Environmental impacts of trade are often not integrated with economic analysis of trade. In this paper, to identify and fill important knowledge gaps, we apply an integrated framework of telecoupling (socioeconomic and environmental interactions over distances). The framework of telecoupling, which is more comprehensive and cross-disciplinary than the energy trade framework, is a useful theoretical and methodological tool for analyzing distant interactions among coupled human and natural systems (including energy systems). Telecouplings widely exist in energy systems with various forms and link energy sustainability of different countries closely, so we proposed some methods for energy sustainability analysis under the framework of telecoupling. From the aspect of causes, a method is proposed to judge whether the telecoupling driven by economic factors is conducive to energy sustainability. From the aspect of effects, a method is proposed to assess whether an event is conducive to energy sustainability. The telecoupling framework presents opportunities for more profound and comprehensive understanding of energy sustainability. - Highlights: • A new perspective to study energy sustainability under telecoupling is proposed. • Methods for assessing the causes and effects of energy sustainability are proposed. • Some specific examples of telecoupling in the energy systems are demonstrated.

  13. The dual sustainability of wind energy

    Academics, practitioners, and policy makers continue to debate the benefits and costs of alternative sources of energy. Environmental and economic concerns have yet to be fully reconciled. One view is that decisions that incorporate both society's concern with the environment and investors' desire for shareholder value maximization are more likely to be truly sustainable. We coin the term dual sustainability to mean the achievement of environmental and financial sustainability simultaneously. Many experts believe that wind energy can help to meet society's needs without harming future generations. It is clean and renewable. Because the fuel is free it provides the ultimate in energy independence. Wind energy has emerged as a leading prospect, in part, because it is considered by many to be environmentally sustainable. However, a key question that remains is whether wind energy is financially sustainable without the extensive government support that has helped to create and nurture this growth industry. Using reliable, proprietary data from field research, our analysis employs a capital budgeting framework to evaluate the financial economics of investments in wind energy. We find that because of the convergence of improved technology, greater efficiency, and with the increasing cost of traditional, competing sources such as oil and natural gas, wind energy is close to becoming self-sustaining financially without the extensive federal government support that exists today. Wind energy can provide the best of both worlds. It is sustainable from an environmental perspective and it is becoming sustainable financially. In short, those companies investing in wind energy will be able to do well by doing good. Perhaps the achievement of dual sustainability is true sustainability. Our research findings and dual sustainability have several interesting and important implications for public policy towards wind energy. All imply that public policy can now be

    2013-11-01

    Full Text Available With energy security, climate change mitigation, and sustainable development as three main motives, global energy policies have evolved, now asking for higher shares of renewable energies, shale oil and gas resources in the global energy supply portfolios. Yet, concerns have recently been raised about the environmental impacts of the renewable energy development, supported by many governments around the world. For example, governmental ethanol subsidies and mandates in the U.S. are aimed to increase the biofuel supply while the water footprint of this type of energy might be 70–400 times higher than the water footprint of conventional fossil energy sources. Hydrofracking, as another example, has been recognized as a high water-intensive procedure that impacts the surface and ground water in both quality and quantity. Hence, monitoring the water footprint of the energy mix is significantly important and could have implications for energy policy development. This paper estimates the water footprint of current and projected global energy policies, based on the energy production and consumption scenarios, developed by the International Energy Outlook of the U.S. Energy Information Administration. The outcomes reveal the amount of water required for total energy production in the world will increase by 37%–66% during the next two decades, requiring extensive improvements in water use efficiency of the existing energy production technologies, especially renewables.

    2012-01-01

    The authors analyze the Mexican energy policy taking as reference the methodological framework for sustainable energy development proposed by the Economic Commission for Latin America and the Caribbean. This methodology takes eight related indicators to the social, environmental and economic dimensions in order to calculate a general sustainability indicator for the energy sector. In this methodology, the weight of each dimension is different; namely, the social and environmental issues have less relevance than the economic issues. The authors use this methodology because government institutions as the Department of Energy and the Department of Environment and Natural Resources have used some indicators from such a methodology to propose plans, programs, projects and bills. Authors know of the existence of other methodologies about sustainability. Nonetheless, opting for the Economic Commission for Latin America and the Caribbean's methodology is convenient because this organization is a respectable authority for civil servants from the Mexican institutions. Our objective is just to contrast the sustainability grade of the energy sector between 1990 and 2008 for Mexico whose government started reforms in the 1990s. It concludes that those reforms did not bring about a higher sustainability level for the energy sector. - Highlights: ► We used the OLADE, CEPAL and GTZ's methodology to calculate sustainability indicators for the Mexican energy sector. ► We studied the Mexican energy policy from 1990 to date and presented it. ► Currently, the Mexican energy sector is less sustainable than in 1990.

    Energy planning represents an investment-decision problem. Investors commonly evaluate such problems using portfolio theory to manage risk and maximize portfolio performance under a variety of unpredictable economic outcomes. Energy planners need to similarly abandon their reliance on traditional, ''least-cost'' stand-alone technology cost estimates and instead evaluate conventional and renewable energy sources on the basis of their portfolio cost--their cost contribution relative to their risk contribution to a mix of generating assets. This report describes essential portfolio-theory ideas and discusses their application in the Western US region. The memo illustrates how electricity-generating mixes can benefit from additional shares of geothermal and other renewables. Compared to fossil-dominated mixes, efficient portfolios reduce generating cost while including greater renewables shares in the mix. This enhances energy security. Though counter-intuitive, the idea that adding more costly geothermal can actually reduce portfolio-generating cost is consistent with basic finance theory. An important implication is that in dynamic and uncertain environments, the relative value of generating technologies must be determined not by evaluating alternative resources, but by evaluating alternative resource portfolios. The optimal results for the Western US Region indicate that compared to the EIA target mixes, there exist generating mixes with larger geothermal shares at equal-or-lower expected cost and risk.

    Besides technical, political and economic aspects of energy sustainability there are several social, behavioural and psychological dimensions of vital importance for a successful implementation of Renewable Energy Systems (RES) and Rational Use of Energy (RUE) within communities. The European Project ''Sustainable Communities-on the energy dimension'' pursues an interdisciplinary approach to detect essential success and facilitating factors. In the last years social and psychological aspects in the process of sustainability came to the fore more and more. Not only as a complementary science to facilitate the technical aims in the change process but also as an essential part for success. (authors)

    The energy performance of large building portfolios is challenging to analyze and monitor, as current analysis tools are not scalable or they present derived and aggregated data at too coarse of a level. We conducted a visualization design study, beginning with a thorough work domain analysis and a characterization of data and task abstractions. We describe generalizable visual encoding design choices for time-oriented data framed in terms of matches and mismatches, as well as considerations for workflow design. Our designs address several research questions pertaining to scalability, view coordination, and the inappropriateness of line charts for derived and aggregated data due to a combination of data semantics and domain convention. We also present guidelines relating to familiarity and trust, as well as methodological considerations for visualization design studies. Our designs were adopted by our collaborators and incorporated into the design of an energy analysis software application that will be deployed to tens of thousands of energy workers in their client base.

    Highlights: • Analyzes energy R&D decisions with uncertainty in research outcomes and markets. • R&D is shown to be more valuable in second-best planning and policy environments. • Deterministic R&D approaches likely undervalue the optionality of technologies. - Abstract: The allocation of research and development (R&D) funds across a portfolio of programs must simultaneously consider uncertainty from research outcomes and from market acceptance of the resulting technologies. We introduce a stochastic R&D portfolio management framework for addressing both sources of uncertainty and present numerical results for energy technology R&D strategy under uncertainties in climate policy and natural gas prices. Numerical experiments indicate that R&D may be more valuable in second-best planning environments where decision-makers use expected-value approaches, and recourse investments occur after R&D has reduced costs. We also find that deterministic R&D valuation approaches likely overestimate the expected value of R&D success but undervalue the optionality and hedging potential of technologies relative to sequential decision-making approaches under uncertainty. The results also highlight the role of R&D in second-best policy environments.

    'Sustainable' is an old established term which has made a political career in the past ten years. The roots of this career extend back into the 18th century, when an economic concept of forest management was developed to replace yield maximization achieved by means of complete deforestation by yield optimization attained by conservative forest management. This latter type of forest management was termed 'sustainable'. The language used in today's sustainability debate was based on the idea of preserving the capital provided by nature and living on the interest. As a consequence, the term 'sustainable' became one of the key points in environmental policy and economic policy after the Brundtland report had been published (V. Hauff, 1987), which also constitutes the background to this article. (orig.) [de

    2017-01-01

    Research sponsored by the US Department of Energy (DOE) aims to facilitate a clean and independent energy future for the nation. Strategic planning for energy research and development (R&D) can be complex and dynamic, in part due to federal budgetary constraints and volatility. Managing R&D funding to advance energy technologies, in spite of these challenges, is a crucial component of the nation's long term energy policy. This study demonstrates a portfolio decision analysis (PDA) approach to support R&D resource allocation decisions for the DOE Office of Fossil Energy's Carbon Capture and Storage R&D program. A multi-attribute value model uses technology readiness levels (TRLs) and other metrics to represent the overall objectives of the R&D program in order to evaluate alternative research portfolios given limited funding. Mathematical optimization identifies efficient funding allocations for each technology program area to maximize the multi-attribute value generated from the total budget. This is especially useful for responding to externally imposed budget changes. As the case study demonstrates, explicitly funding the most value-generating options leads to greater expected R&D programmatic value than typical strategies of equal or proportional distributions of a budget change among technology program areas. - Highlights: • Decision analysis can minimize the effect of a budget decrement on an R&D program. • Greater expected benefits are yielded by differentially funding technologies. • Budget scenario testing illustrates factors that influence value generation. • Coordinating with US DOE bridges gap between decision research and practice.

  8. Sustainable Mobility: Using a Global Energy Model to Inform Vehicle Technology Choices in a Decarbonized Economy

    2013-04-01

    Full Text Available The reduction of CO2 emissions associated with vehicle use is an important element of a global transition to sustainable mobility and is a major long-term challenge for society. Vehicle and fuel technologies are part of a global energy system, and assessing the impact of the availability of clean energy technologies and advanced vehicle technologies on sustainable mobility is a complex task. The global energy transition (GET model accounts for interactions between the different energy sectors, and we illustrate its use to inform vehicle technology choices in a decarbonizing economy. The aim of this study is to assess how uncertainties in future vehicle technology cost, as well as how developments in other energy sectors, affect cost-effective fuel and vehicle technology choices. Given the uncertainties in future costs and efficiencies for light-duty vehicle and fuel technologies, there is no clear fuel/vehicle technology winner that can be discerned at the present time. We conclude that a portfolio approach with research and development of multiple fuel and vehicle technology pathways is the best way forward to achieve the desired result of affordable and sustainable personal mobility. The practical ramifications of this analysis are illustrated in the portfolio approach to providing sustainable mobility adopted by the Ford Motor Company.

    Highlights: • Sustainable Development needs a better definition in relation to Energy. • Emerging energy technologies present very positive features for sustainability. • Renewable energies still need a lot of R and D for advancing in their learning curves. • Nuclear Energy has a very appealing potential as a non-CO 2 technology. • Electric cars are the best option for solving energy sustainability in transportation. - Abstract: Energy for Sustainable Development is analyzed as a Technology challenge with a very large set of possibilities both in energy generation and energy consumption. The portfolio of emerging technologies in both domains is very large but also very demanding. Their learning curves show very different features, and inherent difficulties in each technology can be identified. Additionally, energy sustainability conveys rigorous considerations about Global Warming and ancillary subjects, which are not yet properly defined in terms of requirements on the energy sectors. Moreover, the evolution of energy generation sources in the first decade of this century clearly shows a mismatch between the theoretical boost to combat climate change, and the actual facts in energy markets. However, emerging technologies in the complete energy sector could give a suitable answer to a challenge not very well defined so far

    2008-11-01

    The article deals with indicators framework to monitor implementation of the main EU (European Union) directives and other policy documents targeting sustainable energy development. The main EU directives which have impact on sustainable energy development are directives promoting energy efficiency and use of renewable energy sources, directives implementing greenhouse gas mitigation and atmospheric pollution reduction policies and other policy documents and strategies targeting energy sector. Promotion of use of renewable energy sources and energy efficiency improvements are among priorities of EU energy policy because the use of renewable energy sources and energy efficiency improvements has positive impact on energy security and climate change mitigation. The framework of indicators can be developed to establish the main targets set by EU energy and environmental policies allowing to connect indicators via chain of mutual impacts and to define policies and measures necessary to achieve established targets based on assessment of their impact on the targeted indicators representing sustainable energy development aims. The article discusses the application of indicators framework for EU sustainable energy policy analysis and presents the case study of this policy tool application for Baltic States. The article also discusses the use of biomass in Baltic States and future considerations in this field.

    Full Text Available In the United States, there is no comprehensive energy policy at the federal level. To address issues as diverse as climate change, energy security, and economic development, individual states have increasingly implemented Renewable Portfolio Standards (RPSs, which mandate that utility providers include a specified amount of electricity from renewable energy sources in their total energy portfolios. Some states have included incentives for individual energy technologies in their RPS, such as solar electric (also called photovoltaic or PV technology. Here, we use GIS to visualize adoption of RPSs and electricity generation from renewable energy sources in the US and examine changes in renewable electricity and solar electric generation over time with the goal of informing future policies aimed at promoting the adoption of renewable energy technologies.

  17. Energy and sustainable development: issues and options

    Future development needs to be sustainable in all of its dimensions if it is to continue to fully contribute to human welfare. In the achievement of this objective, the manner in which energy is produced and consumed is of crucial importance. In the wake of these insights, first attempts begin to provide concrete options for steps towards sustainability in the energy sector. Two criteria can be identified for developing sustainable development policies. First, such policies need to strike a balance between the three dimensions of sustainable development - economic, environmental and social - acknowledging that all three are intrinsically linked. Second, policies in the energy sector need to reduce exposure to large-scale risks and improve the resilience of the energy system through active risk management and diversification. (authors)

  20. Portfolio and diversity analysis of energy technologies using full-spectrum risk measures

    2005-01-01

    Energy diversity and security have been evaluated using the multi-criteria diversity analysis (MDA) of A. C. Stirling as well as more classical Markowitz mean-variance portfolio (MVP) theory. Each of these approaches is capable of producing an efficient frontier that shows optimal generating portfolio mixes, those that maximize performance (i.e. minimize cost) while minimizing risk or uncertainty (i.e. maximizing diversity). MDA covers the full-spectrum of uncertainty, reaching into areas where little is known about the range of possible outcomes, let alone their probabilities. However, MDA does not exploit statistical information that is available in certain parts of the risk-spectrum where historic means, variances and co-variances of outcomes are known and can be used to make inferences about the future. MVP operates precisely in this space. However, like other capital market models, its prescriptive value rests on the idea that the past is the best guide to the future. As such MVP can be blind to unforeseen events that create future structural change. Used in isolation, therefore, neither model offers a fully satisfying result. An MVP analysis of energy technologies tells us how to create generating portfolios with minimum cost and risk (cost-variance), assuming historic ranges predict the future well enough. If policy makers are confident that past expected values, ranges and variances will continue, then the solutions are fine. But what about so-called unknown risks? Possible future events that may produce outcomes with unknown consequences? This is where MDA becomes a potentially powerful tool. This project seeks to merge the two approaches and to map the space between optimal MVP and MDA solutions using a combined MVP+MDA optimization and weighting scheme. Placing 100% of the emphasis on MVP, for example, produces results based purely on historical trends. These may serve for short planning horizons. On the other hand, giving MDA a 100% weighting produces

    The twenty-first century will be an era in which sustainability will be a powerful value espoused by the community. The sustainability of energy, in terms of production and consumption, and in relation to the broader impacts of energy on society and the environment, will be a particular focus of the community. Australia, as a nett exporter of energy, and with a high per capita energy consumption, has both an economic and environmental imperative to be a leader in sustainable energy concepts and technologies. Australia therefore needs to position itself strategically, with a policy framework that facilitates the strategic positioning, to use and foster its diverse resources to provide for the social and economic needs of this generation, in a manner that ensures that the energy needs of the future generations can be met. The Institution of Engineers Australia has developed a Position on Sustainable Energy. The principles and actions through which the country's transition to a sustainable energy future will be managed are outlined

    The potential for widespread use of domestically available energy resources, in conjunction with climate change concerns, suggest that biomass may be an essential component of U.S. energy systems in the near future. Cellulosic biomass in particular is anticipated to be used in increasing quantities because of policy efforts, such as federal renewable fuel standards and state renewable portfolio standards. Unfortunately, these independently designed biomass policies do not account for the fact that cellulosic biomass can equally be used for different, competing energy demands. An integrated assessment of multiple feedstocks, energy demands, and system costs is critical for making optimal decisions about a unified biomass energy strategy. This study develops a spatially explicit, best-use framework to optimally allocate cellulosic biomass feedstocks to energy demands in transportation, electricity, and residential heating sectors, while minimizing total system costs and tracking greenhouse gas emissions. Comparing biomass usage across three climate policy scenarios suggests that biomass used for space heating is a low cost emissions reduction option, while biomass for liquid fuel or for electricity becomes attractive only as emissions reduction targets or carbon prices increase. Regardless of the policy approach, study results make a strong case for national and regional coordination in policy design and compliance pathways.

  6. Nuclear energy in a sustainable development perspective

    International Nuclear Information System (INIS)

    2000-01-01

    The concept of sustainable development, which emerged from the report of the 1987 World Commission on Environment and Development (the Brundtland report), is of increasing interest to policy makers and the public. In the energy sector, sustainable development policies need to rely on a comparative assessment of alternative options, taking into account their economic, health, environmental and social aspects, at local, regional and global levels. This publication by the OECD Nuclear Energy Agency investigates nuclear energy from a sustainable development perspective, and highlights the opportunities and challenges that lie ahead in this respect. It provides data and analyses that may help in making trades-off and choices in the energy and electricity sectors at the national level, taking into account country-specific circumstances and priorities. It will be of special interest to policy makers in the nuclear and energy fields

  7. Can renewable energy sources sustain affluent society?

    1995-01-01

    Figures commonly quoted on costs of generating energy from renewable sources can give the impression that it will be possible to switch to renewables as the foundation for the continuation of industrial societies with high material living standards. Although renewable energy must be the sole source in a sustainable society, major difficulties become evident when conversions, storage and supply for high latitudes are considered. It is concluded that renewable energy sources will not be able to sustain present rich world levels of energy use and that a sustainable world order must be based on acceptance of much lower per capita levels of energy use, much lower living standards and a zero growth economy.

    The global issue of climate change has put pressure on governments to de-carbonise their energy portfolios by transitioning from the dominant use of fossil fuels energy to extensive use of renewable energies. The lack of renewable energy laws and credible targets and valid roadmaps for energy policies within the MENA region has let to ambitious and unrealistic renewable targets, where countries such as Djibouti and Morocco are aiming for 100% and 42% renewables respectively, by 2020, while Kuwait and Qatar are only aiming for 5% and 6% respectively. Nevertheless, this demonstrates the commitment and desirability of the members of the MENA region on increasing their share of renewables in their energy mix to reduce the greenhouse gas emissions of the region and minimise the unintended impacts of energy technologies on major natural resources through use of cost efficient technologies. The Relative Aggregate Footprint (RAF) of energy sources among the member states of the MENA region is assessed by applying the "System of Systems (SoS) Approach to Energy Sustainability Assessment" (Hadian and Madani, 2015). RAF demonstrates the efficiency of the overall resource-use of energy resources through creating a trade-off between carbon footprint, land footprint, water footprint, and economic cost. Using the resource availability of each member states, weights are assigned to the four criteria. This allows the evaluation of the desirability of energy sources with respect to regional resource availability and therefore, the efficiency of the overall resource-use of the energy portfolio of the MENA region is determined. This study has recognised the need for reform and radical changes within the MENA region's energy profile to make a significant contribution to the reduction of carbon emissions in order to use the resources in a sustainable way and increase the regional energy security of the member states across MENA.

    2004-01-01

    There is general agreement that hydrogen as an universal energy carrier could play increasingly important role in energy future as part of a set of solutions to a variety of energy and environmental problems. Given its abundant nature, hydrogen has been an important raw material in the organic chemical industry. At recent years strong competition has emerged between nations as diverse as the U.S., Japan, Germany, China and Iceland in the race to commercialize hydrogen energy vehicles in the beginning of 21st Century. Any form of energy - fossil, renewable or nuclear - can be used to generate hydrogen. The hydrogen production by nuclear electricity is considered as a sustainable method. By our presentation we are trying to evaluate possibilities for sustainable hydrogen production by nuclear energy at near, medium and long term on EC strategic documents basis. The main EC documents enter water electrolysis by nuclear electricity as only sustainable technology for hydrogen production in early stage of hydrogen economy. In long term as sustainable method is considered the splitting of water by thermochemical technology using heat from high temperature reactors too. We consider that at medium stage of hydrogen economy it is possible to optimize the sustainable hydrogen production by high temperature and high pressure water electrolysis by using a nuclear-solar energy system.

    2008-01-01

    Energy sustainability is becoming an increasing issue-or rather 'the' issue in our society. Often it is reduced to a purely technical problem. Renewable energies and energy-efficient technologies are developed to solve the problem, but finally the end-users will 'decide' how much and what kind of energy they are going to consume. This article is targeted on showing the environmental psychological aspects of the change of energy demand and supply. It builds upon a transactional model of human technology interchange and summarises environmental psychological work done during more than 5 years. It refers to the idea of energy sustainable communities (ESCs), shows the development of one example community and concentrates on one aspect of the social dimension of ESCs, the 'acceptance of renewable energy technology', its definition and measurement in Germany

    IIASA's Environmentally Compatible Energy Strategies (ECS) Project has proposed a quantitative 'working definition' of sustainable development E3 (energy-economic-environmental) scenarios. ECS has proposed four criteria for sustainability: economic growth is sustained throughout the time horizon; socioeconomic inequity among world regions is reduced over the 21st century; reserves-to-production (R/P) ratio for exhaustible primary energy resources do not decline; and long-term environmental stress is mitigated. Using these criteria, 40 long-term E3 scenarios generated by ECS models were reviewed and analyzed. Amongst the conclusions drawn were: slow population growth or stabilization of global population appears to be prerequisite for sustainable development; economic growth alone does not guarantee a sustainable future; carbon intensities of total primary energy must decrease faster than the historical trend; strategies for fossil fuel consumption must aim at non-decreasing R/P ratios; and carbon emissions must be near or below today's levels at the end of this century. The analysis of sustainable development scenarios is an important step towards formulating long-term strategies aimed at climate stabilization. 6 figs., 1 tab.

    Massachusetts Institute of Technology (MIT) partnered with the U.S. Department of Energy (DOE) to develop and implement solutions to retrofit existing buildings to reduce energy consumption by at least 30% as part of DOE’s Commercial Building Partnerships (CBP) Program.1 Lawrence Berkeley National Laboratory (LBNL) provided technical expertise in support of this DOE program. MIT is one of the U.S.’s foremost higher education institutions, occupying a campus that is nearly 100 years old, with a building floor area totaling more than 12 million square feet. The CBP project focused on improving the energy performance of two campus buildings, the Ray and Maria Stata Center (RMSC) and the Building W91 (BW91) data center. A key goal of the project was to identify energy saving measures that could be applied to other buildings both within MIT’s portfolio and at other higher education institutions. The CBP retrofits at MIT are projected to reduce energy consumption by approximately 48%, including a reduction of around 72% in RMSC lighting energy and a reduction of approximately 55% in RMSC server room HVAC energy. The energy efficiency measure (EEM) package proposed for the BW91 data center is expected to reduce heating, ventilation, and air-conditioning (HVAC) energy use by 30% to 50%, depending on the final air intake temperature that is established for the server racks. The RMSC, an iconic building designed by Frank Gehry, houses the Computer Science and Artificial Intelligence Laboratory, the Laboratory for Information and Decision Systems, and the Department of Linguistics and Philosophy.

  3. An Ad-Hoc Initial Solution Heuristic for Metaheuristic Optimization of Energy Market Participation Portfolios

    Directory of Open Access Journals (Sweden)

    Ricardo Faia

    2017-06-01

    Full Text Available The deregulation of the electricity sector has culminated in the introduction of competitive markets. In addition, the emergence of new forms of electric energy production, namely the production of renewable energy, has brought additional changes in electricity market operation. Renewable energy has significant advantages, but at the cost of an intermittent character. The generation variability adds new challenges for negotiating players, as they have to deal with a new level of uncertainty. In order to assist players in their decisions, decision support tools enabling assisting players in their negotiations are crucial. Artificial intelligence techniques play an important role in this decision support, as they can provide valuable results in rather small execution times, namely regarding the problem of optimizing the electricity markets participation portfolio. This paper proposes a heuristic method that provides an initial solution that allows metaheuristic techniques to improve their results through a good initialization of the optimization process. Results show that by using the proposed heuristic, multiple metaheuristic optimization methods are able to improve their solutions in a faster execution time, thus providing a valuable contribution for players support in energy markets negotiations.

    The electric utility sector is of central importance for economic growth and social development. While numerous societal and economic benefits arise from electricity production, it can also have impacts which may not be fully and unanimously reconciled with the concept of sustainability. Moving the electricity sector towards sustainable development calls for the integration of environmental, social and economic aspects in the decision-making process. As an input to such a process, one needs to assess how the different options perform with respect to specific sustainability criteria. As a part of the ''Comprehensive Assessment of Energy Systems'', carried out by the Paul Scherrer Institute (PSI), the electricity and heat supply systems are examined in view of sustainability criteria and the associated indicators, thus allowing operationalization of the sustainability concept

    Though hundreds of billions of dollars have been invested, past development efforts have been largely unable to break the cycle of poverty - a cycle that is directly linked to the provision of energy. Too often, the potential of local enterprises to provide essential energy services has been ignored. Yet such an enterprise is one of the most potent engines for shifting towards a local human capacity to produce and distribute modern energy services. This recognition lies at the heart of REED, an approach to developing new sustainable energy enterprises that use clean, efficient and renewable energy technologies to meet the energy needs of underserved populations.

    The wide use of nuclear energy has promoted the development of China's economy and the improvement of people's living standards. To some extent, the exploitation of nuclear power plants will solve the energy crisis faced with human society. Before the utilization of nuclear fusion energy, nuclear fission energy will be greatly needed for the purpose of alleviating energy crisis for a long period of time. Compared with fossil fuel, on the one hand, nuclear fission energy is more cost-efficient and cleaner, but on the other hand it will bring about many problems hard to deal with, such as the reprocessing and disposal of nuclear spent fuel, the contradiction between nuclear deficiency and nuclear development. This paper will illustrate the future and prospect of nuclear energy from the perspective of the difficulty of nuclear development, the present reprocessing way of spent fuel, and the measures taken to ensure the sustainable development of nuclear energy. By the means of data quoting and comparison, the feasibility of sustainable development of nuclear energy will be analyzed and the conclusion that as long as the nuclear fuel cycling system is established the sustainable development of nuclear energy could be a reality will be drawn.

The conclusion is that such development will be possible. The necessary renewable energy sources are present, if further technological improvements...

  11. Carbon Impact Analytics - How to measure the contribution of a portfolio to the energy and climate transition

    International Nuclear Information System (INIS)

    2015-01-01

    In a world transitioning to a low-carbon economy, it is crucial that investors and asset managers are equipped with strategies and tools to choose the financial assets most likely to thrive. Carbon Impact Analytics is an answer to this pressing yet unfulfilled need. This methodology was developed by Carbone 4 in collaboration with Mirova, Natixis Asset Management subsidiary dedicated to responsible investment. MAIF, a mutual insurance company, is also an early sponsor of the methodology. Carbon Impact Analytics (CIA) intends to measure and compare the contribution of financial assets and portfolios to the low-carbon economy. In this first version, the methodology covers corporate equities and bonds, with an international scope. This guide details the methodological principles of Carbon Impact Analytics. It is aimed at portfolio managers and asset owners interested in implementing Carbon Impact Analytics, and more broadly, to anyone seeking details on the methodology. Analysis of the carbon impact of a portfolio begins with an in-depth assessment of each underlying firm, followed by aggregation at the portfolio level. This allows for differentiation between companies in the same business sector, and enables recognition of companies' efforts in integrating climate and energy-related issues in their strategic decisions and reporting. Challenges regarding the low-carbon transition vary depending on the characteristics of each economic sector. Therefore, Carbon Impact Analytics differentiates 'high stakes' and 'low stakes' sectors, and provides specific insights for 'high stakes' sectors with tailored calculation principles for each sector. 'High stakes' sectors for which a detailed Carbon Impact analysis is performed are detailed. Aggregation at portfolio level eliminates emissions double-counting. Double-counting of GHG emissions arises when the same ton of GHG emissions is counted more than once within a portfolio due to the aggregation of companies' indirect

    The Republic of Croatia has been building the Krsko Nuclear Power Plant and is participating in all the activities necessary for a successful operating of the plant now for almost thirty years. However, in the light of the nuclear energy renaissance it is necessary to prepare ourselves for new challenges, stricter criteria of safety and protection, respect the indispensability of continuous re-examination of safety of procedures and methods. The of Croatia has strictly committed herself to the nuclear energy programme development-CRONEP in accordance with the methodology of the International Atomic Energy Agency. Certainly, in the first moment till the possible decision on the building of nuclear power plant, it will be necessary to make an institutional framework and create human resources and such an infrastructure that will be able to, when the decision will be taken, support the project and realize it with maximal efficiency. We consider it the unique way in which it is possible to avoid what proved to be the weakness of some projects of nuclear power plants, that is missing a deadline and problems concerning financing that are intolerable taking into account the value of the investment. Likewise, since the Conference is dedicated to small and medium-sized electric networks or to small nuclear power programmes, it needs to be mentioned that except the largest facilities it should be promoted researching of nuclear power reactors of medium size whose development somehow falls behind in this moment Medium size reactors gives great advantages to smaller economies in technical and financial sense. From the current standpoint solutions of viability of nuclear programmes through re-processing of the spent nuclear fuel in new generation of power plants are discernible. Since today's technologies are sufficiently safe there is no need to wait with this development and fuel from one generation shall be re-processed into the fuel for the next generation of reactors.

    A joint industry approach is needed to put in place a sustainable energy system that is economically and technologically feasible. The industry sectors involved must include the renewable energy industry, energy efficiency industry and the natural gas industry. Conventional forecasts of energy futures make far less use of these industries than is economically and technically feasible. Existing forecasts make the trade off between acceptable levels of economic growth, limitation of greenhouse gases and dependence on coal and oil appear more difficult than they actually are and overlook the benefits of sustainable energy industry development. This paper outlines how national gains from carefully targeted action can exceed national losses while substantially reducing greenhouse gases and creating jobs at zero or negative costs.

    Almost 40 years after the Agency’s founding, the IEA responsibility for ensuring access to global oil supplies is still a core mandate. Yet over the course of its history, the IEA’s responsibilities have expanded along with both the international energy economy and conceptions of energy security itself. Our mission to promote secure and sustainable energy provision spans the energy mix. At the same time, a changing global energy map means that the industrialised nations of the world no longer dominate energy consumption. The IEA must work in close co-operation with partner countries and organisations worldwide to achieve its three core objectives: energy security, economic prosperity, and environmental sustainability. Working toward international commitments to reduce greenhouse gas emissions that cause global climate change; facilitating energy technology exchange, innovation and deployment; improving modern energy access to the billions of people who are without it; bolstering both cleanliness and security through energy efficiency; and promoting flexible and functioning energy markets – these efforts complement our traditional core responsibilities of mitigating the effects of supply disruptions and improving statistical transparency.

    In this article the results of a study on sustainability of energy crops are discussed. Contribution to the reduction of the greenhouse effect and other environmental effects were investigated for the Netherlands. The study assumed that energy crops are grown on set-aside land or grain land. Generating electricity and/or heat from hemp, reed, miscanthus, poplar and willow show the best prospects. These crops are sustainable and may in the future be economically feasible. Ethanol from winter wheat shows the most favourable environmental effects, but is not economically efficient. Liquid fuels from oil seed rape and sugar beet are not very sustainable. 2 tabs., 4 refs

    Full Text Available Risk analysis and management currently have a strong presence in financial institutions, where high performance and energy efficiency are key requirements for acceleration systems, especially when it comes to intraday analysis. In this regard, we approach the estimation of the widely-employed portfolio risk metrics value-at-risk (VaR and conditional value-at-risk (cVaR by means of nested Monte Carlo (MC simulations. We do so by combining theory and software/hardware implementation. This allows us for the first time to investigate their performance on heterogeneous compute systems and across different compute platforms, namely central processing unit (CPU, many integrated core (MIC architecture XeonPhi, graphics processing unit (GPU, and field-programmable gate array (FPGA. To this end, the OpenCL framework is employed to generate portable code, and the size of the simulations is scaled in order to evaluate variations in performance. Furthermore, we assess different parallelization schemes, and the targeted platforms are evaluated and compared in terms of runtime and energy efficiency. Our implementation also allowed us to derive a new algorithmic optimization regarding the generation of the required random number sequences. Moreover, we provide specific guidelines on how to properly handle these sequences in portable code, and on how to efficiently implement nested MC-based VaR and cVaR simulations on heterogeneous compute systems.

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

    At the U.N. Commission on Sustainable Development (CSD), the role of nuclear power for a carbon free emission supply of energy is now being recognized although with certain reticence or opposition. Such recognition is taking place at the current cycle of discussions devoted to sustainable energy, industrial development, atmospheric pollution and climate change issues. This paper focuses on the arguments and facts provided during CSD deliberations for considering nuclear energy as a valid option: all available energy sources will need to be considered for an adjustment to a world that requires much less carbon liberation to the environment; in the transportation sector, actions need to be urgently implemented for promoting cleaner fuels and more efficient vehicles; massive reduction of greenhouse gas emissions must be urgently implemented in order to mitigate the impacts of global warming; sustainable energy solutions for developed economies are not always adequate in developing countries; the development evolution requires specifically tailored solutions to conditions of large annual growth-rates of energy demand. Consequently, nuclear power will provide the answer to many of these problems. (Author)

    International Nuclear Information System (INIS)

    2003-01-01

    The U.N. World Summit on Environment and Development in Rio de Janeiro in June 1992 was the origin of the international framework for sustainable development. As a basis for joint, sustainable action by governments, organizations, industries, and the public, the participating countries signed the Rio Declaration on Environment and Development, and drafted the associated action program, Agenda 21. Sustainable development comprises these three determinant factors: - Economy. - Ecology. - Social aspects. This is where entrepreneurial responsibility for society comes in. If industries want to generate overall positive effects, they must be efficient, competitive, and profitable on a long-term basis. Power supply systems meeting the criteria of sustainable development must be reliable, economically viable, socially acceptable, and environmentally compatible. The power supply in Finland is meeting these sustainability requirements in many ways. Finland's electricity supply is decentralized, using a variety of energy sources. Electricity can be generated and made available at low cost. The Finnish power industry is an important employer and a major factor in the economy. Moreover, electricity is generated in advanced types of power plants. In this way, the structure of the Finnish power supply system incorporates important factors of sustainable development. (orig.)

    One of the major challenges of sustainable urban development is ensuring a sustainable energy supply while minimizing negative environmental impacts. The European Union Directive 2009/28/EC has set a goal of obtaining 20 percent of all energy from renewable sources by 2020. In this context, it is possible to consider the use of residues from forest maintenance, residues from livestock, the use of energy crops, the recovery of food waste, and residuals from agro-industrial activities. At the same time, it is necessary to consider the consequent environmental impact. In this paper an approach in order to evaluate the environmental compatibility has presented. The possibilities of national priorities for commissioning of power plants on biofuel and other facilities of distributed generation are discussed.

    In order to assess the sustainable development of China’s energy objectively and accurately, we need to establish a reasonable indicator system for energy sustainability and make a targeted comprehensive assessment with the scientific methods. This paper constructs a comprehensive indicator system for energy sustainability from five aspects of economy, society, environment, energy resources and energy technology based on the theory of sustainable development and the theory of symbiosis. On this basis, it establishes and discusses the assessment models and the general assessment methods for energy sustainability with the help of fuzzy mathematics. It is of some reference for promoting the sustainable development of China’s energy, economy and society.

    Because the world population is likely to double over the next century, with most of the increase being in the developing countries, the stresses caused by a lack of energy will increase unless tackled with determination. A truly global effort led by the industrialized countries is called for. The WEC advocates specific actions to be taken. It takes decades for energy projects to build up the required critical mass to impact on a global scale. Unless action is taken now to accelerate these processes, the future sustainability of energy production and use runs the risk of being badly compromised, to the disadvantage of all

    Full Text Available Energy is one of the basic needs of humanity and, for ages, the sun seemed to be the main source ofall energy in the universe and that is why the ancient Egyptians used to venerate it. Many wastes andcorpses – under pressure and heat – have been converted throughout the years inside the earth intothe oil on which recent development is totally based to support humans’ life, particularly intransportation and power generation. As time passes, it has been proven that oil will vanish. For thefirst moment, it seemed like mankind will certainly suffer due to such a hard situation and some peoplethought that we will get back to stone ages when oil no longer exists. Thanks for the Renewable Energy scientist who has looked at the issue from a different prospective,that is, even if oil vanishes, the main reason of its existence is still there, that is the sun . The sun has the capability to still make people enjoy their life not only by enjoying the sunny weatherin many places of the world and having good times on the beach for those who live by the sea but alsothe sun can still provide man with required energy and cause the wind to blow, the waves to raise, theplants to be converted to biomass, and the earth to store its geothermal energy. As long as life goes on, the sun will always rise and will always grant its energy to mankind. It is theclean, renewable and sustainable energy, which guarantees sustainable development. Because of the high correlation between renewable energy and sustainable development, the editorialteam of this journal thought of offering a hub to researchers interested in these two important fields topresent their work and share it with others who have the same interest in such a wide area ofresearch .

    2009-07-01

    This paper discussed social motivations related to household energy conservation. The aim of the study was to explore how technology can be designed and used in the home to encourage sustainable energy use. The basic techniques used to motivate sustainable energy action included behaviour change techniques; information techniques; positive motivational techniques; and coercive motivational techniques. The psychological theories used in the study included cognitive dissonance as a means of reminding people of the inconsistency of their attitudes towards energy and their behaviour, and utility theory as a means of determining personal motivations for energy conservation. The study showed that people are more motivated to act when presented with personalized information and monetary losses as opposed to monetary gain. Social value orientation and self-reflection motivations were also considered. The study showed that pro-social orientation can be used in the form of ambient displays located in public areas of the home. Self-reflection can be encouraged by allowing family members to annotate visualizations containing a history of their energy consumption data. Results of the study will be used to design actual feedback visualizations of energy use. 18 refs.

    Stakeholders often have competing interests when selecting or planning new power plants. The purpose of developing this preliminary Electricity Portfolio Simulation Model (EPSim) is to provide a first cut, dynamic methodology and approach to this problem, that can subsequently be refined and validated, that may help energy planners, policy makers, and energy students better understand the tradeoffs associated with competing electricity portfolios. EPSim allows the user to explore competing electricity portfolios annually from 2002 to 2025 in terms of five different criteria: cost, environmental impacts, energy dependence, health and safety, and sustainability. Four additional criteria (infrastructure vulnerability, service limitations, policy needs and science and technology needs) may be added in future versions of the model. Using an analytic hierarchy process (AHP) approach, users or groups of users apply weights to each of the criteria. The default energy assumptions of the model mimic Department of Energy's (DOE) electricity portfolio to 2025 (EIA, 2005). At any time, the user can compare alternative portfolios to this reference case portfolio.

    2003-01-01

    Agenda 21 formulated in connection with the UN-Summit in Rio de Janeiro summarises the demands and suggestions concerning a sustainable energy use and energy supply: 'Energy is essential to economic and social development and improved quality of life. Much of the world's energy, however, is currently produced and consumed in ways that could not be sustained if technology were to remain constant and if overall quantities were to increase substantially.' Since the adoption of Agenda 21 the energy issue has been at the centre of the Rio process, either directly, if aspects of supply for humans are concerned, or indirectly, if the anthropogenic greenhouse effect is dealt with. Germany takes an active role in participating in the Rio process, adopting it to national conceptions and supporting other countries on their path to Sustainable Development. Milestones of the German Rio Process are the commitment to the goals and actions of the Rio Declaration and the Agenda 21 as well to the corresponding UN conventions. The German Federal Government has taken several actions. In summer 2000 the Federal Cabinet adopted a bill according to which a Council for Sustainable Development (Nachhaltigkeitsrat) was to be instituted at the beginning of 2001. The Council's task is to participate in the development and formulation of a sustainability strategy for the Federal Republic of Germany. Furthermore, the Federal Government has agreed on the institution of a State Secretary Committee for Sustainable Development. The Committee's task is among other things to define concrete projects for the implementation of the federal sustainable strategy. (BA)

  9. Supply side energy management for sustainable energy ( development in Pakistan

    2005-01-01

    Pakistan is an energy deficient country. Indigenous reserves of oil and gas are limited and the country heavily depends on imported energy. The indigenous coal is of poor quality. Environmental pollution and greenhouse gas emissions from energy use are becoming significant environmental issues in the country. Sustainability is regarded as a major consideration for both urban and rural development in Pakistan. People in the country have been exploiting the natural resources with no consideration to the effects-both short term (environmental) and long term (resource crunch). The urban areas of the country depend to a large extent on commercial energy sources. The rural areas use non-commercial sources like firewood, agricultural wastes and animal dung. Even this is decreasing over the years, with the villagers wanting to adopt the ready to use sophisticated technology. The debate now is to identify a suitable via media. The option that fills this gap aptly is the renewable energy source. This paper analyses the supply side management of energy resources in relation to sustainable energy development. The present study shows that for achieving long-term environmental sustainable development, renewable energy is the major option that could meet the growing energy needs in Pakistan. (author)

  11. No sustainable development without an energy policy

    2000-01-01

    The energy crisis of 1973, and again during the 1980s, prompted industrialized countries to adopt measures to reduce energy usage and to encourage conservation practices. Energy consumption in the transportation field was particularly high. However, after a while, some of the measures were either dropped or not enforced and our energy utilization continued to intensify. It soon became apparent that a different approach was required. At the Rio Conference in 1992, the idea of sustainable development was introduced with the objective to reduce global warming. The utilization of fossil fuels amplifies the emissions of greenhouse gases resulting in global warming which threatens the entire environment and also the health of citizens, particularly those living in cities. In 1997, 160 countries signed the Kyoto Protocol. Canada committed to reduce emissions of greenhouse gases by 6 per cent compared to 1990 levels, and this between 2008 and 2012. It is obvious that drastic steps are needed in order for Canada to meet this commitment. After an extensive analysis of the situation by various committees, it was concluded that activities related to the transportation of people in particular contribute greatly to the emission of greenhouse gases. The results also indicate that solutions need to be found to reduce energy consumption. The author recommended the adoption of intelligent structures and materials which imitate biological systems in a predictable manner to optimize certain functions. He also recommended a better integration of energy policy with the basic principles of sustainable development. 10 refs., 4 tabs

    2016-01-01

    In this review, we summarize research efforts to realize Na-based organic materials for novel battery chemistries. Na is a more abundant element than Li, thereby contributing to less costly materials with limited to no geopolitical constraints while organic electrode materials harvested from biomass resources provide the possibility of achieving renewable battery components with low environmental impact during processing and recycling. Together, this can form the basis for truly sustainable electrochemical energy storage. We explore the efforts made on electrode materials of organic salts, primarily carbonyl compounds but also Schiff bases, unsaturated compounds, nitroxides and polymers. Moreover, sodiated carbonaceous materials derived from biomasses and waste products are surveyed. As a conclusion to the review, some shortcomings of the currently investigated materials are highlighted together with the major limitations for future development in this field. Finally, routes to move forward in this direction are suggested. PMID:28773272

    2010-01-01

    Present trends of electrical energy supply and demand are not sustainable because of the huge gap between demand and supply in foreseeable future in India. The path towards sustainability is exploitation of energy conservation and aggressive use of renewable energy systems. Potential of renewable energy technologies that can be effectively harnessed would depend on future technology developments and breakthrough in cost reduction. This requires adequate policy guidelines and interventions in the Indian power sector. Detailed MARKAL simulations, for power sector in India, show that full exploitation of energy conservation potential and an aggressive implementation of renewable energy technologies lead to sustainable development. Coal and other fossil fuel (gas and oil) allocations stagnated after the year 2015 and remain constant up to 2040. After the year 2040, the requirement for coal and gas goes down and carbon emissions decrease steeply. By the year 2045, 25% electrical energy can be supplied by renewable energy and the CO 2 emissions can be reduced by 72% as compared to the base case scenario. (author)

  17. An analysis of Renewable Portfolio Standard policy formulation and its influence on state level energy prices

    Science.gov (United States)

    McCollester, Peter Colin

    Over the past two decades, environmental concern has crept to the forefront of the world policy agenda. This concern has manifested itself differently throughout the world. In the United States, this has come in the form of Renewable Portfolio Standards (RPS) which have become one of the primary policy tools which states use to encourage renewable energy generation. The advent of RPS has spurred intense debate at a federal and state level, centering on the economic merits of promoting renewable energy generation. Detractors argue that RPS will raise electricity rates, since generation from renewable sources is typically costlier than energy generated from fossil fuels. At this point, evidence to the relationship between RPS on electricity prices remains unclear. Researchers have attempted to understand this relationship through a variety of means. The most common being regression based models, which utilize readily available United States Energy Information Agency (US EIA) data, and have uncovered a number of important independent variables which are incorporated into the model in this study. Examples include personal income, state population, and deregulation of an energy market. In addition to empirical studies, the National Renewable Energy Laboratory (NREL) has created complex mathematical models which generate scenario projections based on a number of assumptions. While interesting, these are forward looking tools and as such have not yielded a tremendous amount of insight into the underlying policy mechanics of RPS. A challenge of addressing this topic which is worth noting is that much of the research available which analyzes the merits of RPS caters to distinct political or private sector agendas. The research gathered for this study is comprehensive, and attempts to avoid studies with any clear political, ideological, or financial motivation. Using the insights from previous researchers this study develops a rigorous fixed effects regression model to

    2014-11-01

    Full Text Available The aim of this work is to evaluate the sustainability, in terms of greenhouse gases emission saving, of a new potential bio-ethanol production chain in comparison with the most common ones. The innovation consists of producing bio-ethanol from different types of no-food grapes, while usually bio-ethanol is obtained from matrices taken away from crop for food destination: sugar cane, corn, wheat, sugar beet. In the past, breeding programs were conducted with the aim of improving grapevine characteristics, a large number of hybrid vine varieties were produced and are nowadays present in the Viticulture Research Centre (CRA-VIT Germplasm Collection. Some of them are potentially interesting for bio-energy production because of their high production of sugar, good resistance to diseases, and ability to grow in marginal lands. Life cycle assessment (LCA of grape ethanol energy chain was performed following two different methods: i using the spreadsheet BioGrace, developed within the Intelligent Energy Europe program to support and to ease the Renewable Energy Directive 2009/28/EC implementation; ii using a dedicated LCA software. Emissions were expressed in CO2 equivalent (CO2eq. These two tools gave very similar results. The overall emissions impact of ethanol production from grapes on average is about 33 g CO2eq MJ–1 of ethanol if prunings are used for steam production and 53 g CO2eq MJ–1 of ethanol if methane is used. The comparison with other bio-energy chains points out that the production of ethanol using grapes represents an intermediate situation in terms of general emissions among the different production chains. The results showed that the sustainability limits provided by the normative are respected to this day. On the contrary, from 2017 this production will be sustainable only if the transformation processes will be performed using renewable sources of energy.

  2. Accelerating the transition to sustainable energy systems

    International Nuclear Information System (INIS)

    Jefferson, Michael

    2008-01-01

    The slow pace of transition to sustainable energy systems is the result of several factors running in parallel. The starting points are very low. Even 30% per annum increases in rated capacity (for wind energy or solar PV, for example) take many years to make a big impact at the global level. Policy initiatives are for the most part ineffectual in relation to the urgency and scale of what is required, and often fail to address the fundamental causes of this slow progress. This reflects a 'top-down' approach-often accompanied by unrealistic targets and simultaneously undermined by a lack of consistency across policies, which reflect a 'utopian social engineering mentality', made worse because: 'The Planner's response to failure of previous interventions (is) to do more intensive and comprehensive interventions' as William Easterly has put it. In short, there is little or no accountability. This approach has failed to harness the sympathy, imagination, self-interest, or sound options of energy users-although it may attract developers, including those not hitherto noted for renewable energy projects or environmental concern. Targets are usually too short term and clearly unrealistic, especially where fossil fuel use is rising very rapidly, and renewable energy use expands modestly. Government subsidies for traditional energy forms continue. Insufficient attention is paid to what individuals might achieve in energy efficiency and renewable energy terms if permitted to have, or retain (in industrialized countries, where the burden of taxation is often inhibiting), the wherewithal to make the necessary investments. Subsidy systems often promote renewable energy schemes that are misdirected and buoyed up by grossly exaggerated claims. One or two mature renewable energy technologies are pushed nationally with insufficient regard for their costs, contribution to electricity generation, transportation fuels' needs, or carbon emission avoidance. Investors are rewarded

    2017-03-01

    Full Text Available Among the regulatory policies, feed-in tariffs (FIT and renewable portfolio standards (RPS are the most popular to promote the development of renewable energy power industry. They can significantly contribute to the expansion of domestic industrial activities in terms of sustainable energy. In this paper, we synthetically consider various important factors with the analysis of the existing literature, and use system dynamics (SD to establish models of long-term development of the renewable energy power industry under FIT and RPS schemes. The model not only clearly shows the complex logical relationship between the factors but also reveals the process of coordination between the two policy tools in the development of the renewable energy power industry. In addition, as an example of development of renewable energy industry, the paper studies the development of China’s photovoltaic power industry under different scenarios. The models proposed in this paper can provide a reference for scholars to study development of the renewable energy power industry in different countries, thereby facilitating an understanding of the renewable energy power’s long-term sustainable development pattern under FIT and RPS schemes, and helping to provide references for policy-making institutions. The results show that in the perfect competitive market, the implementation of RPS can promote long-term and rapid development of China’s photovoltaic power industry given the constraints and actions of the mechanisms of RPS quota proportion, the TGC valid period, and fines, compared with FIT. At the end of the paper, policy implications are offered as references for the government.

    Darkwa, K.

    2001-10-01

    The economic survival of any nation depends upon its ability to produce and manage sufficient supplies of low-cost safe energy. The world's consumption of fossil fuel resources currently increasing at 3% per annum is found to be unsustainable. Projections of this trend show that mankind will exhaust all known reserves in the second half of the coming century. Governments, industrialists, commercial organizations, public sector departments and the general public have now become aware of the urgent requirements for the efficient management of resources and energy-consuming activities. Most organizations in the materials, manufacturing and retail sectors and in the service industries have also created energy management departments, or have employed consultants, to monitor energy consumption and to reduce wastage. Conversely, any sustained attempt to reduce rates of energy consumption even by as little as 0.1% per annum ensures relatively an eternal future supply as well as reduction on environmental and ecological effect. Thus, there is no long- term solution to energy flow problem other than systematic and effective energy management and the continuous application of the techniques of energy management. Essential energy management strategies in support of a sustainable energy- economy are discussed.

  6. Sustainable electric energy supply by decentralized alternative energy technologies

    The most available and affordable sources of energy in today's economic structure are fossil fuels, namely, oil, gas, and coal. Fossil fuels are non-renewable, have limited reserves, and have serious environmental problems associated with their use. Coal and nuclear energy are used in central and bulky power stations to produce electricity, and then this electricity is delivered to customers via expensive transmission lines and distribution systems. Delivering electric power via transmission and distribution lines to the electricity users is associated with high electric power losses. These power losses are costly burdens on power suppliers and users. One of the advantages of decentralized generation (DG) is that DG is capable of minimizing power losses because electric power is generated at the demand site. The world is facing two major energy-related issues, short term and long term. These issues are (i) not having enough and secure supplies of energy at affordable prices and (ii) environmental damages caused by consuming too much energy in an unsustainable way. A significant amount of the current world energy comes from limited resources, which when used, cannot be replaced. Hence the energy production and consumption do not seem to be sustainable, and also carries the threat of severe and irreversible damages to the environment including climate change.The price of energy is increasing and there are no evidences suggesting that this trend will reverse. To compensate for this price increase we need to develop and use high energy efficient technologies and focusing on energy technologies using renewable sources with less energy conversion chains, such as solar and wind. The world has the potential to expand its capacity of clean, renewable, and sustainable energy to offset a significant amount of greenhouse gas emissions from conventional power use. The increasing utilization of alternative sources such as hydro, biomass, geothermal, ocean energy, solar and

    Deregulation and new environmental requirements combined with the growing scarcity of fossil resources and the increasing world energy demand lead to a renewal of the debate on tomorrow's energies. Specifically, nuclear energy, which has undeniable assets, faces new constraints. On the one hand, nuclear energy is very competitive and harmless to greenhouse effect. From this point, it seems to be an ideal candidate to reach future objectives of sustainability, availability and acceptability. On the other hand, its technology of production - based on fission - remains imperfect and generates risks for environment and health. In this respect, it is less desirable. Therefore, world researchers turn today towards another type of nuclear technique, fusion, on which the project ITER is founded. This worldwide project is interesting for our analysis because, as a technological revolution, it takes into consideration all the global challenges of nuclear energy for the future, and particularly its capacity to meet the increasing energy needs of developing countries. It is the example par excellence of a successful international scientific collaboration oriented towards very long-run energy ends that involve huge technological, economic and political stakes. Focusing on this project, we thus have to reconsider the future place of nuclear energy in a more and more demanding world. Considering the magnitude of the efforts undertaken to implement ITER, this paper aims at analysing, in a detailed way, its goals, its challenges and its matter

    The role of energy in pursuit of policies seeking sustainable development is crucial. Correspondingly, the work of energy economists will be affected in many traditional areas of analysis and will require enhanced scope and new expertise. This would lead to a better understanding of the place of natural resources in the production process, better delineation of trade-offs between avoidance of ecological degradation and economic stagnation, and more interdisciplinary feed-back.

    The conventional desalination processes are not only energy intensive but also environment un-friendly. They are operating far from thermodynamic limit, 10–12%, making them un-sustainable for future water supplies. An innovative desalination processes are required to meet future sustainable desalination goal and COP21 goal. In this paper, we proposed a multi-effect desalination system operated with ocean thermocline energy, thermal energy harnessed from seawater temperature gradient. It can exploit low temperature differential between surface hot water temperature and deep-sea cold-water temperature to produce fresh water. Detailed theoretical model was developed and simulation was conducted in FORTRAN using international mathematical and statistical library (IMSL). We presented four different cases with deep-sea cold water temperature varies from 5 to 13°C and MED stages varies from 3 to 6. It shows that the proposed cycle can achieve highest level of universal performance ratio, UPR = 158, achieving about 18.8% of the ideal limit. With the major energy input emanated from the renewable solar, the proposed cycle is truly a “green desalination” method of low global warming potential (GWP), best suited for tropical coastal shores having bathymetry depths up to 300m or more.

    A hybrid energy system in the form of the Object structure is the pattern for the structure of options in the evaluation of a hybrid system. The Object structure is defined as: Hybrid Energy System {[production (solar, wind, biomass, natural gas)] [utilization(electricity, heat, hydrogen)]}. In the evaluation of hybrid energy systems only several options are selected to demonstrate the sustainability assessment method application in the promotion of the specific quality of the hybrid energy system. In this analysis the following options are taken into a consideration: 1.Solar photo-voltaic power plant (PV PP), wind turbine power plant (WTPP) biomass thermal power plant (ThSTPP) for electricity, heat and hydrogen production. 2.Solar PV PP and wind power plant (WPP) for electricity and hydrogen production. 3.Biomass thermal steam turbine power plant (BThSTPP) and WPP for heat and hydrogen production. 4.Combined cycle gas turbine power plant for electricity and hydrogen production. 5.Cogeneration of electricity and water by the hybrid system. The sustainability assessment method is used for the evaluation of quality of the selected hybrid systems. In this evaluation the following indicators are used: economic indicator, environment indicator and social indicator

    Full Text Available In this paper, results are reported of a technology assessment of the use and integration of decentralized energy systems and storage devices in an urban renewal area. First the general context of a different approach based on 'rethinking' and the incorporation of ongoing integration of coming economical and environmental interests on infrastructure, in relation to the sustainable urban development and regeneration from the perspective of the tripod people, technology and design is elaborated. However, this is at different scales, starting mainly from the perspective of the urban dynamics. This approach includes a renewed look at the ‘urban metabolism’ and the role of environmental technology, urban ecology and environment behavior focus. Second, the potential benefits of strategic and balanced introduction and use of decentralized devices and electric vehicles (EVs, and attached generation based on renewables are investigated in more detail in the case study of the ‘Merwe-Vierhaven’ area (MW4 in the Rotterdam city port in the Netherlands. In order to optimize the energy balance of this urban renewal area, it is found to be impossible to do this by tuning the energy consumption. It is more effective to change the energy mix and related infrastructures. However, the problem in existing urban areas is that often these areas are restricted to a few energy sources due to lack of available space for integration. Besides this, energy consumption in most cases is relatively concentrated in (existing urban areas. This limits the potential of sustainable urban regeneration based on decentralized systems, because there is no balanced choice regarding the energy mix based on renewables and system optimization. Possible solutions to obtain a balanced energy profile can come from either the choice to not provide all energy locally, or by adding different types of storage devices to the systems. The use of energy balance based on renewables as a

    Full Text Available The aim of this work is to evaluate the sustainability, in terms of greenhouse gases emission saving, of a new potential bio-ethanol production chain in comparison with the most common ones. The innovation consists of producing bio-ethanol from different types of no-food grapes, while usually bio-ethanol is obtained from matrices taken away from crop for food destination: sugar cane, corn, wheat, sugar beet. In the past, breeding programs were conducted with the aim of improving grapevine characteristics, a large number of hybrid vine varieties were produced and are nowadays present in the CRA-VIT (Viticulture Research Centre Germplasm Collection. Some of them are potentially interesting for bio-energy production because of their high production of sugar, good resistance to diseases, and ability to grow in marginal lands. LCA (Life Cycle Assessment of grape ethanol energy chain was performed following two different methods: (i using the spreadsheet “BioGrace, developed within the “Intelligent Energy Europe” program to support and to ease the RED (Directive 2009/28/EC implementation; (ii using a dedicated LCA software. Emissions were expressed in CO2 equivalent (CO2eq. The results showed that the sustainability limits provided by the normative are respected to this day. On the contrary, from 2017 this production will be sustainable only if the transformation processes will be performed using renewable sources of energy. The comparison with other bioenergy chains points out that the production of ethanol using grapes represents an intermediate situation in terms of general emissions among the different production chains.

    Highlights: • This paper presents a MILP model for optimal design of multi-energy microgrids. • Our microgrid design includes optimal technology portfolio, placement, and operation. • Our model includes microgrid electrical power flow and heat transfer equations. • The case study shows advantages of our model over aggregate single-node approaches. • The case study shows the accuracy of the integrated linearized power flow model. - Abstract: Optimal microgrid design is a challenging problem, especially for multi-energy microgrids with electricity, heating, and cooling loads as well as sources, and multiple energy carriers. To address this problem, this paper presents an optimization model formulated as a mixed-integer linear program, which determines the optimal technology portfolio, the optimal technology placement, and the associated optimal dispatch, in a microgrid with multiple energy types. The developed model uses a multi-node modeling approach (as opposed to an aggregate single-node approach) that includes electrical power flow and heat flow equations, and hence, offers the ability to perform optimal siting considering physical and operational constraints of electrical and heating/cooling networks. The new model is founded on the existing optimization model DER-CAM, a state-of-the-art decision support tool for microgrid planning and design. The results of a case study that compares single-node vs. multi-node optimal design for an example microgrid show the importance of multi-node modeling. It has been shown that single-node approaches are not only incapable of optimal DER placement, but may also result in sub-optimal DER portfolio, as well as underestimation of investment costs.

    The Sustainable Energy Research Center (SERC) project at Mississippi State University included all phases of biofuel production from feedstock development, to conversion to liquid transportation fuels, to engine testing of the fuels. The feedstocks work focused on non-food based crops and yielded an increased understanding of many significant Southeastern feedstocks. an emphasis was placed on energy grasses that could supplement the primary feedstock, wood. Two energy grasses, giant miscanthus and switchgrass, were developed that had increased yields per acre. Each of these grasses was patented and licensed to companies for commercialization. The fuels work focused on three different technologies that each led to a gasoline, diesel, or jet fuel product. The three technologies were microbial oil, pyrolysis oil, and syngas-to liquid-hydrocarbons

    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.

    The concept of sustainability has been given numerous interpretations, some overlapping or complementary, some contradictory. Thus it is difficult to judge whether the nuclear industry does, or does not, meet sustainability criteria; particularly as the present nuclear technologies are not renewable. Uranium resources appear to be of the same order of magnitude as oil and gas resources. This implies that they are a transitional source of energy. There are also other potential arguments against the sustainability of nuclear power: its pollution, risks and costs. Environmental damage may come from various parts of the nuclear fuel cycle. Two types of risk will be discussed: first the risk of major accidents and thereby exceptional environmental damage, and second the risks associated with the proliferation of nuclear weapons. Each of these factors, as well as the pure economic cost of nuclear electricity, ought to be compared to the environmental damage, risks and costs of the available alternatives. Only the Latin American experience will be considered. For example, the need for Mexico to use nuclear power when it has large oil and gas supplies, is considered. (author)

    Full Text Available Development of the concepts of sustainable development and corporate social responsibility has a great impact on reporting in companies. The increase of their importance has resulted in a need to create a reporting system that would provide information on not only the methods but also the results of implementation of those concepts in companies. Globally, there are many organizations that promote and support companies in the area of integrated reporting. The most popular standard for reporting non-financial data that is used by a number of companies worldwide is the Global Reporting Initiative (GRI Guidelines. The main objective of the GRI is to support the development of sustainable economy in which companies take responsibility for the economic, social, and environmental consequences of their operations, manage that responsibility, and report all their actions. An example of a sector where the concept of sustainable development and its transparent reporting has an impact on the formation of values is the energy sector, which creates value for stakeholders and, together with the financial sector, has the greatest impact on national economies.

    In the next years we will face significant switch stands regarding the future energy mix in Europe. In general, European energy policy has to address three energy challenges for a competitive electricity production (1): - Security of supply; - Limitation of greenhouse gas emissions; and - Providing affordable energy to consumers. Regarding climate precaution the goal of a low carbon economy is very ambitious. The NPP in operation already today contribute to all three goals. Nuclear energy generates two thirds of the EU' low carbon electricity, is one of the most economic energy sources and is less vulnerable to fuel price changes, thereby protecting EU economies against the price volatility of raw materials (2). The investment decisions, which have to been taken in the next 5 to 10 years, will determine the electricity production portfolio in the European Union for the next 50 years: 1. Around 800-900 GWe capacity will be required by 2030 to replace the existing capacity and to address increasing demand. 2. More than 50 % of the electricity in 2030 will be generated in plants have not been build today. 3. A total of 57.6 GWe of new nuclear power plants are projected to be commissioned between 2000 and 2030 (3). Only 9.4 GW of these are already certain investments. To ensure sustainable investment decisions, there needs to be reliable and effective framework conditions with the underlying principles: - competition among vendors; - efficient licensing; - solvent capital markets; - political framework; and - public acceptance. With regard to public acceptance, the Commission launched, based on the results of the EU summit in 2007, a platform for a broad stakeholder discussion about risks, challenges and opportunities of nuclear energy, the European Nuclear Energy Forum (ENEF). E.ON is actively involved in both discussion during the annual ENEF-summit and the working group sessions throughout the year. We appreciate these discussion and we face up the pros and

    A discussion is made of the conflicting concepts of sustainable development, focusing primarily on energy resources, as viewed by economists and environmentalists. According to the 'preservationist' view we 'borrow' the Earth from generations to come and have no right to use exhaustible resources. According to 'developmentalists' natural resources are either infinite or can be substituted by alternatives so there is no real problem of exhaustion of resources. It is shown that a compromise between such extreme positions is being forced by the heightened concerns for environmental protection. Outstanding among them are the problems of climate changes resulting from CO 2 (carbon dioxide) emissions from fossil fuel combustion. The energy consumed at present by industrialized and developing countries, and their projections to the year 2020 will be presented as well as the serious environmental consequences of a 'business-as-usual' scenario. These consequences will be much harder to cope with in the developing countries. Carbon emissions will be shown to increase with population, GDP and the 'energy intensity' of the economy. The 'decarbonization' trends of the present economies will be related to the decrease in total fertility rate and 'energy intensity' which is linked to technological advances in energy conservation and structural changes. Mechanisms to accelerate such trends will be discussed as well as financial mechanisms to pay for it, such as carbon taxes. (author) figs., tabs., refs

    Our schools have been involved in several European projects having with the primary objective of educating the young generation to find ways for saving energy and for using the renewable energy. Small changes in our behaviour can lead to significant energy savings and a major reduction in emissions. In our presentation we will refer to three of them: - The Comenius 1 project "Energy in the Consumers' Hands" tried to improve the quality of education for democratic citizenship in all participant schools by creating a model of curricula concerning the integrative teaching of democratic citizenship using the topic approaches based on key concept - energy as important element of the community welfare. The students studied on the following topics: • Sources of energy • The clean use of fossil based resources; • The rational use of energyEnergy and the environment - The project "Solar Schools Forum" (SSF) focuses on environmental education in schools, in particular addressing the topics of Renewable Energy (RE) and Energy Efficiency (EE). The youth need to become more aware of energy-related problems, and how they can change their own lifestyles to limit environmental damage caused by the daily use of energy. As the decision-makers of tomorrow we need to empower them to make the right choices. The SSF is aimed at improving knowledge about RE and EE among children and young people, using a fun approach and aimed at generating greater enthusiasm for clean energy. The youth will also be encouraged to help raise awareness and so act as multipliers in their own communities, starting with their families and friends. As a result of this project we involved in developing and implementing an optional course for high school students within the Solar Schools Forum project. The optional course entitled "Sustainable energy and the environment" had a great deal of success, proof of this success being the fact that it is still taught even today, three years after its

    China is fueling its phenomenal economic growth with huge quantities of coal. The environmental consequences reach far beyond its borders--China is second only to the United States in greenhouse gas emissions. Expanding its supply of other energy sources, like nuclear power and imported oil, raises trade and security issues. Soaring electricity demand necessitates the construction of 40-70 GW of new capacity per year, creating sustained financing challenges. While daunting, the challenge of meeting China's energy needs presents a wealth of opportunities, particularly in meeting demand through improved energy efficiency and other clean energy technologies. The China Energy Group at the Lawrence Berkeley National Laboratory (LBNL) is committed to understanding these opportunities, and to exploring their implications for policy and business. We work collaboratively with energy researchers, suppliers, regulators, and consumers in China and elsewhere to: better understand the dynamics of energy use in China. Our Research Focus Encompasses Three Major Areas: Buildings, Industry, and Cross-Cutting Activities. Buildings--working to promote energy-efficient buildings and energy-efficient equipment used in buildings. Current work includes promoting the design and use of minimum energy efficiency standards and energy labeling for appliances, and assisting in the development and implementation of building codes for energy-efficient residential and commercial/public buildings. Past work has included a China Residential Energy Consumption Survey and a study of the health impacts of rural household energy use. Industry--understanding China's industrial sector, responsible for the majority of energy consumption in China. Current work includes benchmarking China's major energy-consuming industries to world best practice, examining energy efficiency trends in China's steel and cement industries, implementing voluntary energy efficiency agreements in various

    2011-01-01

    In many rural areas, poor people still depend on wood and other biomass fuels for most of their household and income-generating activities. The difficult, time-consuming work of collecting and managing traditional fuels is widely viewed as women's responsibility, which is a factor in women's disproportionate lack of access to education and income, and inability to escape from poverty. Therefore, it is important for energy access programs to have a special focus on women. New options for energy access and sustainable livelihoods, like small-scale biofuels production, can have dramatic benefits for rural women, and their families and communities. Energy development, as both a driving force and a consequence of such tremendous changes, has had profound impact on economic, social, and environmental development. Rural energy has always been a critical issue due to years of energy shortage for both households and industries. Biomass, for long time, has been the only available fuel in many rural areas. The situation in rural areas is even more critical as local demand for energy outstrips availability and the vast majority of people depend on non-commercial energy supplies. Energy is needed for household uses, such as cooking, lighting, heating; for agricultural uses, such as tilling, irrigation and post-harvest processing; and for rural industry uses, such as milling and mechanical energy and process heat. Energy is also an input to water supply, communication, commerce, health, education and transportation in rural areas. (author)

    Duties and taxes related to energy consumption are discussed intensively in Switzerland in connection with impending National votes on various initiatives and Government proposals. These proposals refer either to new public revenues or to the first steps towards modern and ecologically oriented energy politics. In this Forum representatives with diverse political, economical and scientific background explain their points of view. After an overview on national energy politics and on the pending proposals, the focus shifts to the interplay between the requirements of a sustainable development and a forward-looking scheme of liberalization of the electricity market. As a particular example a recommendation for Switzerland is derived from the consideration of practical experience with legal and promotional measures on the utilization of wind energy in other European countries. Looking into the future, the two last speakers discuss the economic and energetic potentials of efficiency-oriented technologies, and the possible role of new materials like advanced hydrogen-carbon-metals.

    2017-01-01

    Sustainable economic growth and improvement of the social welfare depend upon the sufficient supply of energy resources, while the utilization of energy resources is one of the main factors of environmental degradation. This research is involved with development of a sustainable energy system model and a new method for sustainability assessment. This model represents the flow of energy from primary resources through processing, conversion, and end-use technologies in an optimization framework where the useful energy demand in various social and economic sectors is met. The impact of energy supply and consumption chain on the environment at each level of energy system is also embedded in the model structure. A multi-criteria analysis of changes is then applied and sustainable development indices of the whole system are concluded. Finally, effects of the energy subsidy policy and high economic growth rate on sustainability of the energy system in three scenarios are analyzed. Results demonstrate that energy subsidy decelerates the improvement rate of the total sustainability index. Also, when a high economic growth is accompanied with the energy subsidy this index reduces considerably. Results show that how penetration of renewable energy potentials changes the sustainability situation of energy systems. - Highlights: • Developing a new model for sustainable energy systems. • Presenting a new method for sustainability assessment of energy systems. • Optimizing the energy flow and capacity expansion of Hamedan energy system. • Utilizing an MCDA approach to obtain sustainability indices of the whole system. • Analysis of energy subsidy and high economic growth on energy sustainability.

  14. Of paradise and clean power: The effect of California's renewable portfolio standard on in-state renewable energy generation

    Science.gov (United States)

    Yin, Clifton Lee

    Renewable portfolio standards (RPS), policies that encourage acquisition of electricity from renewable energy sources, have become popular instruments for discouraging the use of climate change inducing-fossil fuels. There has been limited research, however, that empirically evaluates their effectiveness. Using data gathered by three governmental entities -- the federal-level Energy Information Administration and two California agencies, the Employment Development Department and the Department of Finance -- this paper investigates the impact of California's RPS, one of the nation's most ambitious such policies, on in-state renewable energy generation. It finds that the California RPS did not bring about a one-time increase in generation with its inception, nor did it compel an increase in generation over time. These results raise questions as to the best way to structure RPS policies in light of growing interest in the establishment of a national RPS.

  15. Development and sustainability issues - energy scenario

    The 20th century has seen an unprecedented rise in the rate of consumption of material and energy resources. These patterns of growth and consumption have caused enormous strains on the available natural resources and the environment. Further, the benefits of available natural resources have been shared in a highly inequitable manner with a small fraction of mankind using up a large fraction of resources to a level that environmental concerns have become a global matter and are threatening to jeopardize the development of the larger fraction of humanity on grounds of global sustainability. While it has been seen that major achievements in almost all areas of human endeavour in recent times, enabling improvements in quality of life and better control over environmental degradation, there is a new challenge now of sustainability of the development process for the majority of human population. The environment with its large inertia, flexibility and stabilising mechanisms has so far some how copped up at least on a global scale with the unprecedented consumption. However, the recent trends indicate that most of the environment related cycles may not be able to take the continued abuse without disastrous global consequences. Piloting and sustaining the legitimate development of societies particularly those which are left far behind in the march towards better quality of life has, therefore, become a matter which needs very urgent consideration and action. There is thus a strong need for charting of a well deliberated goal oriented action plan with a vision that ensures due attention to the interests of all sections of society on the basis of their justifiable needs

  16. Energy sources for future. Change to a sustainable energy system

    Can Germany give up gasoline and power from coal or nuclear energy and how much does it cost? The book does away with all common misunderstandings due to renewable energy sources and describes a compatible model for a sustainable energy mixing in future. Nevertheless fossil fuels are not denounced but seen as a platform for the advanced system. The author explains first why objections to renewable energy sources base on bad information, and pursues quite an other argumentation as such authors emphasizing the potential of these energy sources. Than he shows in detail the possibility of the optimal energy mixing for biomass, solar power, wind power, geothermal energy, hydropower and energy efficiency. The environment will reward us for this and instead buying expensive resources from foreign countries we will create work places at home. The number of big power plants - taking into account safety risks - will decrease and small units of on-site power generation feeded with this renewable sources will play more and more an important role.

    Ayres, Robert U.; Turton, Hal; Casten, Tom

    2007-01-01

    This paper explores two linked theses related to the role energy in economic development, and potential sources of increased energy efficiency for continued growth with reduced greenhouse gas (GHG) emissions. The first thesis is that, while reduced GHG emissions are essential for long-term global sustainability, the usual policy recommendation of increasing energy costs by introducing a carbon tax may be relatively ineffective under current market structures and have an unnecessarily adverse impact on economic growth. Our second thesis is that there exists a practical near-term strategy for reducing GHG emissions while simultaneously encouraging continued technology-driven economic growth. Moreover, this strategy does not require radical new technologies, but rather improved regulation or-more precisely-better deregulation of the electric power sector. In respect to the first of our two theses, this paper addresses a deficiency in neoclassical economic growth theory, in which growth is assumed to be automatic, inevitable and cost-free. We challenge both the assumption that growth will continue in the future at essentially the same rate ('the trend') as it has in the past, and the corollary that our children's children will inevitably be richer and better able to afford the cost of repairing the environmental damages caused by current generations [Simon et al., The state of humanity.

    MacIsaac, Dan

    2009-11-01

    Reader John Roeder writes about a website associated with David MacKay's book Sustainable Energy-Without the hot air. The book is a freely downloadable PDF (or purchasable) book describing an analysis detailing a low-carbon renewable energy transformation route for a large, modern first world industrial country (the United Kingdom). Written for the layman, the work uses vernacular language, e.g., energy consumption and production in a series of bar charts detailing the impacts of necessary strategies such as population reduction, lifestyle changes, and technology changes. MacKay notes that most reasonable plans have large nuclear and ``clean coal'' or other carbon capture components, lots of pumped heat, wind, and much efficiency improvement. He debunks some sacred cows (roof-mounted micro-turbines; hydrogen-powered cars) while pointing out simple effective technologies such as roof-mounted solar water heaters. Similar modest changes in the U.S. (painting roofs white in the southern half of the country) have strong impacts. MacKay claims that he ``doesn't advocate any particular plan or technology,'' but ``tells you how many bricks are in the lego box, and how big each brick is'' so readers can start making planning decisions.

    1991-07-01

    Increased energy use is a vital pre-requisite for economic development, and less developing countries (LDCs) are struggeling to meet energy needs at acceptable costs. LDC decision-makers share the worldwide environmental concerns, but also face other urgent issues like poverty. The industrialised countries can afford to substitute environmental protection for further material growth, but the LDCs will need concessional funding to participate in addressing global environmental problems. Global financing issues may be analysed and resolved through tradeoffs among several criteria including affordability/additionality, fairness/equity, and economic efficiency. The short-term LDC response to sustainable energy issues will be limited mainly to conventional technologies in efficiency improvements, conservation and resource development. The industrialised nations should provide financial resources to LDCs and develop the technology to be used in the 21st century. Pilot international funds like the Global Environmental Facility and the Ozone Fund will help LDCs participate in the effort to solve global environmental issues. (author) 16 refs.

    energy resources such as wind, solar, small hydro and biomass as alternative energy supplies in this country. Our analysis shows that wind and solar energy can become major contributors towards renewable energy in Kazakhstan. The biomass of agricultural residues, municipal solid waste and wood residues could be used for energy purposes too. Therefore, Kazakhstan should optimize energy consumption and take active and effective measures to increase the contribution of renewables in energy supply to make the country's energy mix environmentally sustainable.

    After 50 plus years of working on uranium fission principles and application, it is a bit hard for me to talk about anything else - but I'll give it a try. To start, I solemnly promise not to recommend to you any new reactor design - be it small, medium, modular, or large. The Uranium-fuelled power plant will be discussed ONLY as a finished product. Note that this sketch is an optional future. Ontario will, of course, take it or leave it, in whole or in part. This paper concentrates on future potential achievements of the CANDU nuclear energy systems. In the past, this venture has produced several modular systems, ranging from small (NPD and CANDU 3), medium (CANDU 6 and 6E) and large (Bruce, Darlington, and CANDU 9). All of these projects are more Ol' less finished products, and yet the CANDU concept still has broad scope for refinement and upgrading. This paper is, however, not about nuclear technology per se, but rather it is about what nuclear energy can do, both now and in the future. What does Ontario need to do next, in the line of technology applications that can help deal with the negative aspects of human-induced climate change? What energy systems can be installed to sustain the wealth and prosperity that Ontario's citizens now enjoy? What are the opportunities and the engineering challenges ahead of us? I do wish to apologize in advance for errors and omissions, and can only hope that missed details do not detract nor completely destroy an optimistic vision. Energy engineering is my game. Economics is not my specialty though it is an integral part of every engineering project. It is likely that the topic of economics will dominate the future choice of world energy supply, whatever that choice may be. Some people claim that the decisive factor dominating decisions with respect to uranium energy will be fear. In fact many opponents of the associated technology aim to induce fear as their main guiding theme. On the contrary, it is more reasonable to expect

    In the fast-growing economies of the Pacific Basin region, sustainability is an important requisite for new energy development. Many countries in this region have seen, and continue to see, very large increases in energy and electricity demand. The investment in any nuclear technology is large. Countries making that investment want to ensure that the technology can be sustained and that it can evolve in an ever-changing environment. Three key aspects in ensuring a sustainable energy future, are technological sustainability, economic sustainability, and environmental sustainability (including resource utilization). The fuel-cycle flexibility of the CANDU reactor provides a ready path to sustainable energy development in both the short and long term. (author)

    2007-01-01

    The European Union has established a number of targets regarding energy efficiency, Renewable Energy Sources (RES) and CO 2 reductions as the 'GREEN PAPER on Energy Efficiency', the Directive for 'promotion of the use of bio-fuels or other renewable fuels for transport' or 'Directive of the European Parliament of the Council on the promotion of cogeneration based on a useful heat demand in the internal energy market'. Many of the according RES and RUE measures are not attractive for investors from an economic point of view. Therefore, governments all over the world have to spend public money to promote these technologies/measures to bring them into market. These expenditures have to be adjusted to budget concerns and should be spent most efficiently. Therefore, the spent money has to be dedicated to technologies and efficiency measures with the best yield in CO 2 reduction without wasting money. The core question: 'How can public money-for promoting sustainable energy systems-be spent most efficiently to reduce GHG emissions?' has well been investigated by the European project Invert. In course of this project, a simulation tool has been designed to answer this core question. This paper describes the modelling with the Invert simulation tool and shows the key features necessary for simulating the energy system. A definition of 'Promotion Scheme Efficiency' is given, which allows estimating the most cost-effective technologies and/or efficiency measures to reduce CO 2 emissions. Investigations performed with the Invert simulation tool deliver an optimum portfolio mix of technologies and efficiency measures for each selected region. Within Invert, seven European regions were simulated and for the Austrian case study, the detailed portfolio mix is shown and political conclusions are derived

    Calgary based Sustainable Energy Technologies is a public company that develops and manufactures alternative energy products that enable distributed renewable energy resources to be integrated with the existing electrical infrastructure. The company has moved from a development stage company to one that manufactures power electronic products that can compete globally and which will play an important role in the transition to a cleaner world. Achievements in the past year have included a joint effort with RWE Piller GmbH to develop a power electronics platform for a fuel cell inverter. Ten inverters were delivered to Nuvera Fuel Cells and were reported to have performed very well in the Avanti distributed generation fuel cell. The universality of the inverter was demonstrated when the same power electronics platform was used to support a 5 kW grid interactive converter for the solar power market. During the 18-month period ending on March 31, 2003, the company invested $1.5 million to create their first two commercial product lines, without net investment of shareholder equity. The objective for the future is to generate cash flow and earnings from sales into the solar power market and to build a leadership role in the stationary fuel cell industry. The major challenge will lie in product support and customer service. As the customer base expands, the company will invest in product-tracking software. This annual report includes an auditor's report, consolidated financial statements including balance sheets, statements of income and deficit, statements of cash flows, and notes to the consolidated financial statements. tabs

    Renewability and sustainability aspects of nuclear energy have been presented on the basis of two different technologies: (1) Conventional nuclear technology; CANDU reactors. (2) Emerging nuclear technology; fusion/fission (hybrid) reactors. Reactor grade (RG) plutonium, {sup 233}U fuels and heavy water moderator have given a good combination with respect to neutron economy so that mixed fuel made of (ThO{sub 2}/RG‐PuO{sub 2}) or (ThC/RG-PuC) has lead to very high burn up grades. Five different mixed fuel have been selected for CANDU reactors composed of 4 % RG‐PuO{sub 2} + 96 % ThO{sub 2}; 6 % RG‐PuO{sub 2} + 94 % ThO{sub 2}; 10 % RG‐PuO{sub 2} + 90 % ThO{sub 2}; 20 % RG‐PuO{sub 2} + 80 % ThO{sub 2}; 30 % RG‐PuO{sub 2} + 70 % ThO{sub 2}, uniformly taken in each fuel rod in a fuel channel. Corresponding operation lifetimes have been found as ∼ 0.65, 1.1, 1.9, 3.5, and 4.8 years and with burn ups of ∼ 30 000, 60 000, 100 000, 200 000 and 290 000 MW.d/ton, respectively. Increase of RG‐PuO{sub 2} fraction in radial direction for the purpose of power flattening in the CANDU fuel bundle has driven the burn up grade to 580 000 MW.d/ton level. A laser fusion driver power of 500 MW{sub th} has been investigated to burn the minor actinides (MA) out of the nuclear waste of LWRs. MA have been homogenously dispersed as carbide fuel in form of TRISO particles with volume fractions of 0, 2, 3, 4 and 5 % in the Flibe coolant zone in the blanket surrounding the fusion chamber. Tritium breeding for a continuous operation of the fusion reactor is calculated as TBR = 1.134, 1.286, 1.387, 1.52 and 1.67, respectively. Fission reactions in the MA fuel under high energetic fusion neutrons have lead to the multiplication of the fusion energy by a factor of M = 3.3, 4.6, 6.15 and 8.1 with 2, 3, 4 and 5 % TRISO volume fraction at start up, respectively. Alternatively with thorium, the same fusion driver would produce ∼160 kg {sup 233}U per year in addition to fission

    Nuclear energy is increasingly perceived as an attractive mature energy generation technology that can deliver an answer to the worldwide increasing energy demand while respecting environmental concerns as well as contributing to a reduced dependence on fossil fuel. Advancing nuclear energy deployment demands an assessment of nuclear energy with respect to all sustainability dimensions. In this paper, the nuclear energy, whose sustainability will be assessed, is governed by the dynamics of three subsystems: environmental, economic, and sociopolitical. The overall sustainability is then a non-linear function of the individual sustainabilities. Each subsystem is evaluated by means of many components (pressure, status, and response). The combination of each group of indicators by means of fuzzy logic provides a measurement of sustainability for each subsystem.

    Full Text Available Energy management can be defined as the process of planning, directing, implementing and controlling the process of generation, transmission and energy consumption. Energy management is a kind of synthesis of phenomena and concepts of modern energy management (management, or the use of modern settings management in the energy sector. Furthermore, when outlining the basic settings for power management Modern management is based on the assumptions of sustainability and conservation of energy stability for present and future generations. Therefore, modern energy management can be seen as a kind of synthesis of three actuarial sciences: energy, sustainable development and management. Sustainable Energy Management is a unique new concept, idea and approach that require many changes in the traditional way of understanding and interpretation of energy management at all levels. Sustainable energy management concept can not therefore be construed as an adopted and defined the concept, but must be constantly modified and adjusted in accordance with changes in the three areas that define it, and in accordance with the specific country or region where applicable. Accordingly, sustainable energy management can be defined as the process of energy management that is based on fundamental principles of sustainable development.

    A constant rebalanced portfolio is an asset allocation algorithm which keeps the same distribution of wealth among a set of assets along a period of time. Recently, there has been work on on-line portfolio selection algorithms which are competitive with the best constant rebalanced portfolio determined in hindsight (Cover, 1991; Helmbold et al., 1996; Cover and Ordentlich, 1996). By their nature, these algorithms employ the assumption that high returns can be achieved using a fixed asset allocation strategy. However, stock markets are far from being stationary and in many cases the wealth achieved by a constant rebalanced portfolio is much smaller than the wealth achieved by an ad hoc investment strategy that adapts to changes in the market. In this paper we present an efficient portfolio selection algorithm that is able to track a changing market. We also describe a simple extension of the algorithm for the case of a general transaction cost, including the transactions cost models recently investigated in (Blum and Kalai, 1997). We provide a simple analysis of the competitiveness of the algorithm and check its performance on real stock data from the New York Stock Exchange accumulated during a 22-year period. On this data, our algorithm outperforms all the algorithms referenced above, with and without transaction costs.

  6. The role of hydropower in environment ally sustainable energy development

    Hydropower has historically been the renewable energy leader, and from a technical-cost perspective, is very likely to remain the only viable renewable energy source for many countries. In recent years, hydropower has been much maligned, especially by NGOs, for not being a sustainable source of energy. Though hydropower is clearly a renewable source of energy, but the question arises whether it can also be sustainable. Hydropower can play an increasingly important role in enabling communities around the world to meet sustainability objectives. To become more accepted as a key contributor to sustainable energy systems, new and existing hydropower projects need to be built and operated in an environmentally, socially and economically sustainable manner. This paper highlights the sustain ability aspects of hydropower and discusses the criteria for selection of environmentally friendly hydropower project sites so that that hydropower can be developed in a sustainable manner and once again be considered favorably in the planning of generation mix for new energy development. Sustainability of hydropower projects involves treating both the social and environmental sustainability of the project at an early stage and including the interests of all stakeholders of the project. As a case study, the Ghazi- Barotha Hydropower Project (GBHP) in Pakistan has been selected, as it is the best example in managing the social issues and gaining public acceptance because of proper planning and addressing environmental and social issues at an early stage.

    Energy is central to current concerns about sustainable human development, affecting economic and social development; economic growth, the local, national, regional, and global environment; the global climate; a host of social concerns, including poverty, population, and health, the balance of payments, and the prospects for peace. Energy is not an end in itself, but rather the means to achieve the goals of sustainable human development. The energy systems of most developing countries are in serious crisis involving insufficient levels of energy services, environmental degradation, inequity, poor technical and financial performance, and capital scarcity. Approximately 2.5 billion people in the developing countries have little access to commercial energy supplies. Yet the global demand for energy continues to grow: total primary energy is projected to grow from 378 exajoules (EJ) per year in 1990 to 571 EJ in 2020, and 832 EJ in 2050. If this increase occurs using conventional approaches and energy sources, already serious local (e.g., indoor and urban air pollution), regional (eg., acidification and land degradation), and global (e.g., climate change) environmental problems will be critically aggravated. There is likely to be inadequate capital available for the needed investments in conventional energy sources. Current approaches to energy are thus not sustainable and will, in fact, make energy a barrier to socio-economic development. What is needed now is a new approach in which energy becomes an instrument for sustainable development. The two major components of a sustainable energy strategy are (1) more efficient energy use, especially at the point of end-use, and (2) increased use of renewable sources of energy. The UNDP Initiative for Sustainable Energy (UNISE) is designed to harness opportunities in these areas to build upon UNDP`s existing energy activities to help move the world toward a more sustainable energy strategy by helping program countries.

    This conference addressed the challenges facing energy markets with particular emphasis on the outlook of winter fuels and prices. It was attended by more than 50 energy marketing professionals representing petroleum producers, pipelines, wholesale marketers, storage companies, end users, banks and government. In order to plan portfolios and reduce risks to their bottom lines, buyers and sellers of energy must always be prepared for unexpected ice storms, major pipeline outages or geopolitical events. Merchants in the fuel supply chain depend on basic analysis, correlations and forecasts of supply/demand, transportation and inventory levels. The conference presented strategies and analysis on how commodity prices will move during the winter; North American supply/demand dynamics for natural gas, electricity, heating oils and natural gas liquids; the interplay of fuel storage and price; fuel switching and its impact on the market; portfolio planning; managing the link between weather and fuel prices; seasonal volatility; and, how liquefied natural gas (LNG) is affecting winter supply. The conference featured 16 presentations, of which 6 have been catalogued separately for inclusion in this database. tabs., figs

In the diagnosis; the evolution and the changes are analyzed foreseen in the international and national environments to establish the form like the energy sector is affected and it responds to these conditions. In second part it revises the strategy to incorporate the required adjustments of agreement with the changes in the environment, the demand perspectives and sector and national politics limits. In the international thing, the process of transformation of the system economic World cup will contribute to strengthen the liberalization actions, deregulation and privatization of the economies of the development countries. Great part of the dynamics growth, will be sustained then in the private investment and in an atmosphere of global competition. The formation of regional blocks opens favorable perspectives for new cooperation forms and development of resources. In the case of the American hemisphere and with reference to the energy sector, one has an important potential to improve the self-sufficiency starting from regional supplies, especially starting from fossil resources. This expectation is important for Colombia that has well-known reservations and important potentials in these resources. The tendencies waited in the fossil resources are more favorable for the countries than they can have reservations and growing production of petroleum and of natural gas. Nevertheless, the development of the coal maintains favorable expectations, but with important requirements as for efficiency and quality in the production that it guarantee the positioning in a more and more concerned market. In the environmental thing, the growth foreseen in the consumption of fossil fuels also bears to the increment in the 2010 in the greenhouse gases, at levels between 36% and 49% superiors to those of 1990.

    In December 1997 Quebec's Minister of Natural Resources requested that the Energy Commission advise him on the quota given to wind energy in the future energy development plans of Hydro-Quebec. The Commission's report to the Minister includes 18 recommendations. Among these is a recommendation that an assessment of wind resources be conducted as soon as possible to identify suitable sites for the installation of wind turbines. A provincial program for the development of wind energy is also recommended, to be initiated by the year 2002, and that it should proceed over the next nine years to reach a target production capacity of 450 MW by the year 2011. This production would come from the yearly installation of 60 to 70 wind turbines of 750 kV. The Commission also recommended that in the initial years costs for this wind energy not exceed that of the Le Nordais project, i.e. 5.8 cents per kWh. Any additional costs incurred in the generation of wind electricity over conventional hydro power should be assumed by the Quebec Government. Conversely, in instances where the wind power is sold to consumers outside of the province, Hydro-Quebec should pay for the full cost of this power. 8 tabs., 1 appendix

    The main objectives of this study are, first, to determine the sustainable energy strategies for green energy supply, and secondly, to derive the green energy recovery ratio and the sustainable green energy progress ratio, and thirdly, to investigate the effects of sustainable energy strategies on these ratios. For these purposes, 20-possible sustainable energy strategies are taken into consideration and are divided into three subgroups that are strategies on the technological impact, sectoral impact, and green energy impact in a society. Using the possible sustainable energy strategies, technological and sectoral impact ratios of green energy and also green energy activity ratio are determined and discussed in detail. Additionally, some Case studies are performed in the scope of this interesting investigation: (i) the effect of technological impact ratio on green energy recovery ratio, and sustainable green energy progress ratio, (ii) the effect of sectoral impact ratio on green energy recovery ratio, and sustainable green energy progress ratio, and (iii) the effect of green energy impact ratio on green energy recovery ratio and sustainable green energy progress ratio. It is found that sustainable green energy progress ratio increases with an increase of technological, sectoral, and green energy impact ratios. This means that all negative effects on the industrial, technological, sectoral and social developments partially and/or completely decrease throughout the transition and utilization to and of green energy and technologies when possible sustainable energy strategies are preferred and applied. Thus, the sustainable energy strategies can make an important contribution to the economies of the countries where green energy is abundantly produced. Therefore, the investment in green energy supply should be, for the future of world nations, encouraged by governments and other authoritative bodies who, for strategic reasons, wish to have a green alternative to fossil

    2003-02-01

    This study introduces mean-variance portfolio theory and evaluates its potential application to the development of efficient (optimal) European Union (EU-15) generating portfolios that enhance energy security and diversification objectives. The analysis extends to European countries the previous work done by Awerbuch in the US, and applies a significantly more detailed portfolio model that reflects the risk of the relevant generating cost streams: fuel, operation and maintenance and construction period costs. It illustrates the portfolio effects of different generating mixes. The study offers preliminary findings on the effects of including more renewable energy sources in the typical EU portfolio mix and suggests interesting directions for further study. The study arises from the perception that these standard, finance-oriented analyses may offer valuable enhancements to energy planning, and concepts of energy security and diversity. Clearly the combination of better portfolio construction and more accurate pricing should lead to more optimal decisions in the round. This study, therefore, represents an effort to complement traditional approaches and point researchers and planners into new territory. The results generally indicate that the existing and projected EU generating mixes are sub optimal - though slightly - from a risk-return perspective, which implies that feasible portfolios with lower cost and risk exist. These can be developed by adjusting the conventional mix and by including larger shares of wind or similar renewable technologies. The results of the portfolio analysis suggest that fixed cost technologies such as renewables must be a part of any efficient generating portfolio. Our assessment of all technologies is limited to risk and cost measures, although other benefits, including low externality costs and sustainability, are often cited for renewables.

  18. Energy sustainability of Microbial Fuel Cell (MFC): A case study

    2017-07-01

    Energy sustainability analysis and durability of Microbial Fuel Cells (MFCs) as energy source are necessary in order to move from the laboratory scale to full-scale application. This paper focus on these two aspects by considering the energy performances of an original experimental test with MFC conducted for six months under an external load of 1000 Ω. Energy sustainability is quantified using Energy Payback Time, the time necessary to produce the energy already spent to construct the MFC device. The results of experiment reveal that the energy sustainability of this specific MFC is never reached due to energy expenditure (i.e. for pumping) and to the low amount of energy produced. Hence, different MFC materials and architectures were analysed to find guidelines for future MFC development. Among these, only sedimentary fuel cells (Benthic MFCs) seem sustainable from an energetic point of view, with a minimum duration of 2.7 years. An energy balance approach highlights the importance of energy calculation. However, this is very often not taken into account in literature. This study outlines promising methodology for the design of an alternative layout of energy sustainable MFC and wastewater management systems.

    Climate change mitigation, if intelligently undertaken, can stimulate economic growth. The main tools available for this task are energy efficiency, renewable energy, and clean energy technologies and services, which are collectively known as sustainable energy. To unleash this potential, the US and other governments need the full cooperation of the sustainable energy industry. This industry knows more than most other about turning energy-related pollution prevention into profits. If engaged, they can help: (1) Identify the economic benefits of greenhouse gas mitigation; (2) Identify barriers to the implementation of greenhouse gas mitigation projects; (3) Develop policies and measures to overcome these barriers; and (4) Implement greenhouse gas mitigation projects. 7 refs.

    Full Text Available In this paper we suggest considering sustainability as a moral framework based on social justice, which can be used to evaluate technological choices. In order to make sustainability applicable to discussions of nuclear energy production and waste management, we focus on three key ethical questions, namely: (i what should be sustained; (ii why should we sustain it; and (iii for whom should we sustain it. This leads us to conceptualize the notion of sustainability as a set of values, including safety, security, environmental benevolence, resource durability, and economic viability of the technology. The practical usefulness of sustainability as a moral framework is highlighted by demonstrating how it is applicable for understanding intergenerational dilemmas—between present and future generations, but also among different future generations—related to nuclear fuel cycles and radioactive waste management.

    Highlights: ► Energy source on the world is tending to run out day by day while the energy need of humanity is increasing simultaneously. ► There are two ways to overcome this problem; one of them is renewable energy sources like solar or wind energy systems. ► The other way is like cogeneration systems. ► Cogeneration system is one of the ways to save the energy and use the energy efficiently. ► A case study is made for a hospital to present the sustainability aspects of cogeneration systems. - Abstract: Cogeneration system (CHP) is one of the ways to save the energy and use the energy efficiently. When compared to separate fossil-fired generation of heat and electricity, CHP may result in a consistent energy conservation (usually ranging from 10% to 30%) while the avoided CO 2 emissions are, as a first approximation, similar to the amount of energy saving. In terms of sustainability, one of the primary considerations is energy efficiency. Sustainable energy is considered as a kind of energy which is renewable and continuous, meaning that the use of such energy can potentially be kept up well into the future without causing harmful repercussions for future generations. In this study, environmental benefits and sustainability aspects of cogeneration systems and importance of those systems to the use of sustainable energy are underlined. To support this idea, first we have referred some scientific studies previously made on cogeneration systems and then we have used our own case study. The case study made on gas engined cogeneration system was applied for a hospital to show the sustainability aspects of cogeneration systems.

    Energy is often known as the catalyst for development. Globally, the per capita consumption of energy is often used as a barometer to measure the level of economic development in a particular country. Realizing the importance of energy as a vital component in economic and social development, the government of Malaysia has been continuously reviewing its energy policy to ensure long-term reliability and security of energy supply. Concentrated efforts are being undertaken to ensure the sustainability of energy resources, both depletable and renewable. The aim of this paper is to describe the various energy policies adopted in Malaysia to ensure long-term reliability and security of energy supply. The role of both, non-renewable and renewable sources of energy in the current Five-Fuel Diversification Strategy energy mix will also be discussed. Apart from that, this paper will also describe the various alternative energy and the implementation of energy efficiency program in Malaysia

    Sustainable development combines development, durability and sustainability. Energy is crucial for development: it brings work, nutrition, health, security, community, etc. Electrical energy offers the most possibilities for the consumer, particularly as regards the problems of pollution on the site of consumption. Nuclear generation is one of the best ways of producing electricity. Midway between stock energies and flow energies, it has several advantages: low consumption of resources, safety, compactness and cleanliness. Waste is not a specifically nuclear problem: it should be considered in terms of a life cycle analysis; construction, dismantling and functioning have to be assessed. The size of certain energies' contribution to the greenhouse effect is therefore made clear. Reprocessing represents a saving of energy, without environmental or health damage. It contributes to energy control, and therefore to sustainable development

    Energy scenarios provide a framework for exploring future energy perspectives, including various combinations of technology options and their implications. Many scenarios in the literature illustrate how energy system developments may affect global change. Examples are the new emissions scenarios by the Intergovernmental Panel on Climate Change (IPCC) and the energy scenarios by the World Energy Assessment (WEA). Some of these scenarios describe energy futures that are compatible with sustainable development goals; such as improved energy efficiencies and the adoption of advanced energy supply technologies. Sustainable development scenarios are also characterized by low environmental impacts (at local, regional and global scales) and equitable allocation of resources and wealth. They can help explore different transitions toward sustainable development paths and alternative energy perspectives in general. The considerable differences in expected total energy requirements among the scenarios reflect the varying approaches used to address the need for energy services in the future and demonstrate effects of different policy frameworks, changes in human behavior and investments in the future, as well as alternative unfolding of the main scenario driving forces such as demographic transitions, economic development and technological change. Increases in research, development and deployment efforts for new energy technologies are a prerequisite for achieving further social and economic development in the world. Significant technological advances will be required, as well as incremental improvements in conventional energy technologies. In general, significant policy and behavioral changes will be needed during the next few decades to achieve more sustainable development paths and mitigate climate change toward the end of the century.

    This book examined selected energy policy issues and challenges confronting Canadians over the last two decades. The aim of the book was to provide an analysis of how energy policy has evolved. The book presents an overview of energy policy and its relationship to sustainable development. Politico-economic contexts were reviewed, including the changing nature of national and continental energy markets, energy policy and sustainable development. The difficulties in evaluating the environment in energy policy were discussed. Issues concerning electricity restructuring in Canada were reviewed, with reference to Canada-US electricity trade and the climate change agenda. Alberta's oil and gas industry and the Kyoto Protocol were also examined, with reference to voluntary measures to address climate change. Issues concerning stewardship, indigenous peoples and petroleum-based economic development in the north were reviewed, as well as northern gas pipeline policy and sustainable development. Conclusions and recommendations were made concerning the following 6 analytical and practical energy policy and governance challenges facing the current government: Kyoto Protocol implementation challenges; energy security; northern pipelines and concerns with Aboriginal peoples and sustainable northern development; electricity restructuring and the limits of regulatory-market design; energy science and technology and innovation policy links; and prospects for turning the struggle for sustainable development in the energy policy field into something closer to an actual achievement. 37 refs

    2017-01-01

    This paper investigates informed public preferences about electricity technologies and portfolios in Germany, qualitatively analyzing opinions, reasoning patterns and judgments of perceived risks and benefits among lay people. The authors developed and applied a ‘mixed-method’ focus group approach involving 130 participants in 15 focus groups throughout Germany. This research aimed to specify participants’ attitudes and preferences regarding electricity technologies and portfolios (evaluation categories); comparatively assess these preferences (technology/portfolio acceptance profiles); and identify participants’ decision-making strategies and processes (decision rule typology). The evaluation basis of people's preferences comprises nine evaluation categories including, among others, trust, national and household economics, and environmental and health impacts. When assessing preferences regarding electricity technologies and portfolios, two overriding results need to be emphasized: first, that selective evaluation patterns produce unique acceptance profiles, and second, that a shift occurs from heterogeneous towards homogeneous evaluation patterns. In relation to decision rules guiding people's preference-making, the research reveals multiple mechanisms are at work when people express preferences about electricity portfolios. Five decision rules were identified regarding how participants dealt with complex portfolio information processing and preference building. - Highlights: • The evaluation basis of people's preferences comprises nine evaluation categories. • Evaluation patterns produce unique technology and portfolio acceptance profiles. • Five generic decision rules guide people's preference-making. • People make decisions in multiple ways using a variety of evaluation strategies. • No ‘one-size-fits-all’ approach for creating insights into the public's approval or rejection of technologies.

    Problems with energy supply and use are related not only to global warming, but also to such environmental concerns as air pollution, ozone depletion forest destruction and emission of radioactive substances. These issues must be taken into consideration simultaneously if humanity is to achieve a bright energy future with minimal environmental impacts. Much evidence exists which suggests that the future will be negatively impacted if humans keep degrading the environment. There is an intimate connection between energy, the environment and sustainable development. A society seeking sustainable development ideally must utilise only energy resources which cause no environmental impact (e.g. which release no emissions to the environment). However, since all energy resources lead to some environmental impact, it is reasonable to suggest that some (not all) of the concerns regarding the limitations imposed on sustainable development by environmental emissions and their negative impacts can be part overcome through increased energy efficiency. A strong relation clearly exists between energy efficiency and environmental impact since, for the same services or products, less resource utilisation and pollution is normally associated with higher efficiency processes. Anticipated patterns of future energy use and consequent environmental impact (Focusing on acid precipitation, stratospheric ozone depletion and the greenhouse effect) are comprehensively discussed in this paper. Also, some solutions to current environmental issues in terms of energy conservation and renewable energy technologies are identified and some theoretical and practical limitations on increased energy efficiency are explained. The relations between energy and sustainable development, and between the environment and sustainable development, are described, and in illustrative example is presented. Throughout the paper several issues relating to energy, environment and sustainable development are examined

    Renewable energy sources should be developed to form the foundation of the global energy structure in the future. This is related to the shortage of fossil energy resources, the greenhouse effects, the increasing number of world's population and the increasing demand for energy and food. Fuels derived from energy crops are not only potentially renewable, but are also sufficiently similar in origin to the fossil fuels to provide direct substitution. They can be converted into a wide variety of energy carriers. Together with solar- and wind technique, adequate energy supply can be to meet the demand of people in rural regions. The concept of Integrated Energy Farms (IEF) has been developed and described in this contribution which includes a decentralised living area from which the daily necessities (food and energy) can be produced directly on-site for approximately 700 people. The area needed to produce biofuels will not exceed 10 % of the whole farm area. (Author)

    nuclear power. For the medium term, 2030-2050, new reactors aiming at reducing capital costs, enhancing safety and improving the efficiency of natural resource use are being developed by designers. In order to address new challenges of deregulated markets, innovative reactor designs should enhance economic competitiveness and reduce financial risks of nuclear energy. The renewed interest of governments for the nuclear option (e.g., US, Finland) has triggered national and international initiatives (GIF, INPRO) aiming at defining and implementing co-operative R and D programmes leading to the deployment of a new generation of nuclear systems meeting the economic, environmental and social goals of sustainable development. International co-operation is essential for a successful renaissance of nuclear energy in the competitive context of the new millennium. Sharing experience, expertise and know-how across countries offers unique opportunities for synergy and cost effectiveness. Intergovernmental organisations such as NEA can play a key role in this regard through providing a framework for exchanging information and undertaking joint projects. (author)

    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.

    Understanding how household practices with regard to energy usage change and how to most effectively encourage the adoption of technologies that utilize renewable energy sources at the residential scale are important issues for addressing the environmental impacts of energy use. Here, the social practices model (Spaargaren, 2003) is applied to examine solar technology adopters in two U.S. States who were interviewed about adopting residential solar electric technology and specifically about their experiences with the rebate and incentive programs available to them. Examining the policies and interrogating their potentially unintended consequences from the perspective of the user sheds light on how residential solar incentive programs act as systems of provision, shaping the practices of solar technology adopters, in hopes of improving these incentive programs and effectively encouraging increased residential solar technology adoption. Findings suggest that feed-in tariffs offer additional positive outcomes related to broadening the context for adoption and encouraging future energy conservation while size restrictions, wholesale pricing in net metering agreements, and inconsistent policy mechanisms across utilities in the same state all have potentially unintended negative consequences. Utilizing a perspective attentive to social practice offers a means of improving the design and implementation of energy policy. - Highlights: • Over half of the U.S. states have implemented renewable portfolio standards (RPS). • RPS mandates sometimes include provisions for residential solar technology. • This solar-sets asides have different implementation structures. • The specifics of these policies affect the actual practices of adopters. • This examination of solar-set aside policy is intended to improve policy

    'Energy Security' has typically, to those involved in making energy policy, meant mostly securing access to oil and other fossil fuels. With increasingly global, diverse energy markets, however, and increasingly transnational problems resulting from energy transformation and use, old energy security rationales are less salient, and other issues, including climate change and other environmental, economic, and international considerations are becoming increasingly important. As a consequence, a more comprehensive operating definition of 'Energy Security' is needed, along with a workable framework for analysis of which future energy paths or scenarios are likely to yield greater Energy Security in a broader, more comprehensive sense. Work done as a part of the Nautilus Institute's 'Pacific Asia Regional Energy Security' (PARES) project developed a broader definition of Energy Security, and described an analytical framework designed to help to compare the energy security characteristics - both positive and negative - of different quantitative energy paths as developed using software tools such as the LEAP (Long-range Energy Alternatives Planning) system.

    2011-10-01

    Full Text Available Since the 1980s sustainability has clearly become the challenge of the 21st century. In a process toward a sustainable society it is crucial that different stakeholders start collaboration and exchange ideas with technicians and academics. To finalize the policy decisions on important issues such as energy sustainability, collaboration between policy makers, academia and the private sector is important. This work intends to give Italian policy makers concrete advice and solutions to develop energy systems for mobility. The analysis proceeds from the context of Sustainability Science, a new science, which has emerged as one of the most important disciplines of international scientific research. Using a new approach, trans-disciplinary and integrated, this research is oriented to study and understand the complexity of the interactions between economy, society and nature. This broad approach permits proposing concrete solutions to complex problems locally and globally. We propose a scheme of definition of Sustainability Energy, defining five pillars of reference, and we redefine the energy systems for mobility in the context of Sustainability Science. In this paper, we start from the idea that we are living in a crucial passage, we are moving from the era of petroleum to the era of energy vectors. Energy systems, including mobility, should be redefined within this new approach.

    Thirty-five years after the Agency's founding, the IEA responsibility for ensuring access to global oil supplies is still a core mandate -- but new energy-related concerns have arisen. Energy security is no longer only about oil. And the industrialised nations of the world are no longer the only major consumers of energy. Climate change driven by greenhouse gas emissions -- 60% of which derive from energy production or use -- is a growing threat. So energy policy was tasked with a new objective: to cut greenhouse gas emissions while maintaining economic growth.

    As the 20th century draws to a close, both individual countries and the world community face challenging problems related to the supply and use energy. These include local and regional environmental impacts, the prospect of global climate and sea level change associated with the greenhouse effect, and threats to international relations in connection with oil supply or nuclear proliferation. For developing countries, the financial cost of providing energy to provide basic needs and fuel economic development pose an additional burden. To assess the magnitude of future problems and the potential effectiveness of response strategies, it is important to understand how and why energy use has changed in the post and where it is heading. This requires study of the activities for which energy is used, and of how people and technology interact to provide the energy services that are desired. The authors and their colleagues have analyzed trends in energy use by sector for most of the world`s major energy-consuming countries. The approach we use considers three key elements in each sector: the level of activity, structural change, and energy intensity, which expresses the amount of energy used for various activities. At a disaggregated level, energy intensity is indicative of energy efficiency. But other factors besides technical efficiency also shape intensity.

    Full Text Available The main objective of this research is to study the role of energy consumption in economic growth in Saudi Arabia over the period of 1971–2012 using the autoregressive distributed lag (ARDL cointegration procedure, and based on neoclassical growth, endogenous growth, and ecological-economics viewpoints. Our empirical results show the existence of a cointegrating relationship between the different variables investigated. In addition, all the inputs (conventional and non-conventional Granger cause economic growth in both the short and long runs. Our findings confirm the energy-led growth hypothesis in the case of Saudi Arabia. Hence, energy conservation policies may deteriorate economic growth in Saudi Arabia if they are not followed by measures that improve energy efficiency, energy saving technologies and encourage the investment and use of renewable energy sources such as solar and wind energies that can participate in the attenuation of climate changes.

  2. Nuclear fuel: sustainable source of energy or burden on society?

    International Nuclear Information System (INIS)

    Williams, T.; Klaiber, G.

    2007-01-01

    In the past, the question concerning the sustainability of a resource primarily addressed its finite nature. Accordingly, electricity production using renewable energies was clearly sustainable. Contrasting this are systems based on oil, gas, coal or uranium. However, from the perspective of 'neo-sustainability' being analyzed today, this assessment appears less clear-cut, especially in light of the definition of sustainability as provided by the Brundtland report. Nowadays, the depletion time of fuel resources is thus not the only significant aspect, but factors such as efficiency, ecofriendliness and social responsibility also figure in. The nuclear fuel supply is analyzed from a sustainability perspective. After a short description of the supply chain, each of the most important aspects of sustainability are related to the individual stages of the supply chain and evaluated. This method aims at answering the question concerning to what extent nuclear fuel is a sustainable source of energy. Although the recycling of fissile materials from reprocessing and the deployment of advanced reactors are key factors as regards the issue of sustainability, these topics are deliberately only touched on. The main focus lies on the sustainability of the nuclear fuel cycle as it is currently utilized in light water reactors, without discussing the subject of reprocessing. (orig.)

    2002-01-01

    From this overall concept of what constitutes sustainability, a range of considerations on equity of energy supply across regions, time scales over which fuel and energy source mixes and technology changes and the like, can be developed. Within the spatial dimension, considerations of sustainability that operate at the global scale need to be translated to the operations of large and small companies, national and local governments down to individual households. It is a complex mix in an increasingly complex world. But one thing is certain, the world's energy demand is going to continue to increase. This demand will be largely satisfied by fossil fuels and this use is not sustainable using current technology in the long term. Massive changes are required to turn the world around onto a more sustainable pathway that will probably take many decades even to make a significant start. The aim of this paper is to briefly explore some of the possible technological options that will guide us on the road to a more sustainable energy future. A genuinely sustainable energy system that also promotes sustainable growth with an improving standard of living for all is obviously a major challenge. At the same time the global demand for energy will continue to increase. On the global scale, the prospect of climate change imposes a major long-term constraint on the use of GHG emitting fuels and generating technologies. The long-term development of a sustainable energy system will require multiple interventions and a pluralistic approach to energy management. Ingredients within the mix are likely to require: 1. innovation in the way we currently generate and supply power 2. continued integration and greater penetration of renewables 3. greater use of embedded and distributed energy generation 4. aggressive end-use efficiency 5. development of technologies to enable continued use of fossil fuels until the transition to sustainability is completed.

  4. Energy indicators for tracking sustainability in developing countries

    Kemmler, Andreas; Spreng, Daniel

    2007-01-01

    Due to the fact that human activities and most sustainability issues are closely related to energy use, the energy system is a sound framework for providing lead indicators for sustainable development. Common energy-economic models enable the estimation of future states of the energy system. An energy system-based lead indicator set can be used to develop consistent and coherent future indicator estimates and to track sustainability, a clear advantage over existing sets. In developed countries, the sustainability discussion is focused on environmental topics, while in developing countries the issues of poverty and equity are equally important. Consequently, for measuring sustainable development in a developing country, the inclusion of a poverty indicator in a set of lead indicators is essential. By correlation and descriptive analysis, it is shown that reliable energy-based indicators of poverty can be created. Although no one-dimensional indicator is a comprehensive measure of poverty, the explanatory power of energy poverty indicators is comparable to that of other poverty indicators. Thus, the use of energy indicators is not restricted to environmental and economic issues but is also relevant for social issues

    The small social acceptance of nuclear power for power generation suggests that in the present situation nuclear technology does not meet certain sustainable criteria. First, the concept of sustainable development is explained and which dimensions can be distinguished. Next, the sustainable development with regard to the development of the energy supply is outlined and the energy policy to obtain this situation is discussed. Subsequently, the impact of the sustainable development and the policy used to realize this on the nuclear technology are dealt with. As a result, criteria are formulated that can be used to verify how nuclear technology will meet this criteria and which demands should be used to fit this technology so it can be used in a sustainable development of the society. 55 refs

    Policies to address long-term energy concerns include a wide range of initiatives. Taxes can internalise costs; financial mechanisms, including subsidies, can target particularly favourable but otherwise non-competitive investments; regulation can apply standards to raise performance of appliances; information programmes can improve decision making; and R and D can make available new options. The 1987 report of the World Commission on Environment and development, found that 'energy efficiency can only buy for the world to develop 'low-energy-paths' based on renewable sources...'. Although many renewable energy systems are in a relatively early stage of development, they offer the world 'a potentially huge primary energy source, sustainable in perpetuity and available in various forms to every nation on Earth.' It suggested that an R and D programme of renewable energy is required to attain the same level of primary energy that is now obtained from a mix of fossil, nuclear, and renewable energy resources. Since renewable energy contributes to all dimensions of sustainable development, one policy challenge is to ensure that renewable energy has a fair opportunity to complete with other resources required for the provision of energy services, especially on 'liberalised' energy markets. This paper gives an overview of rationales for government intervention in energy-related R and D, and international energy R and D trends. it concludes that the liberalisation of energy markets has an overall negative impact on private sector investments in energy R and D and that without a sustained and diverse programme of energy R and D and implementation, we are crippling our ability to make the necessary improvements in the global energy system, especially in light of sustainable development requirements.

    Human society is facing an uncertain future due to the present unsustainable use of natural resources and the growing imbalance with our natural environment. Creation of a sustainable society is a complex multi-disciplinary and multi-stage project, believed to dominate our century, requiring collaboration, teamwork, and abilities to work with respect and learn from other disciplines and professions. Sustainable development means technological progress meeting the present needs without compromising future generation ability to meet its needs and aspirations. It has four aspects: environment, technology, economy, and societal organizations. Students are often taught to deal with technological developments and economic analysis to assess the process or product viability, but are not fully familiar with sustainability and optimization of technology development benefits and the environment. Schools in many disciplines are working to include sustainability concepts into their curricula. Teaching sustainability and renewable energy has become an essential feature today higher education. Sustainable and green design is about designs recognizing the constraints of the natural resource uses and the environment. It applies to all of engineering and science areas, as all systems interact with the environment in complex and important ways. Our project goals are to provide students with multiple and comprehensive exposures to sustainability and renewable energy concepts, facilitating the development of passion and skills to integrate them into practice. The expected outcomes include an increased social responsibility; development of innovative thinking skills; understanding of sustainability issues, and increasing student interests in the engineering and science programs. The project aims to incorporate sustainability and renewable energy concepts into our undergraduate curricula, employing the existing course resources, and developing new courses and laboratory experiments

    We describe and evaluate the technical, political, and economic challenges involved with widespread adoption of renewable energy technologies. First, we estimate fossil fuel resources and reserves and, together with the current and projected global primary power production rates, estimate the remaining years of oil, gas, and coal. We then compare the conventional price of fossil energy with that from renewable energy technologies (wind, solar thermal, solar electric, biomass, hydroelectric, and geothermal) to evaluate the potential for a transition to renewable energy in the next 20-50 years. Secondly, we evaluate - per the Intergovernmental Panel on Climate Change - the greenhouse constraint on carbon-based power consumption as an unpriced externality to fossil-fuel use, considering global population growth, increased global gross domestic product, and increased energy efficiency per unit GDP. This constraint is projected to drive the demand for carbon-free power well beyond that produced by conventional supply/demand pricing tradeoffs, to levels far greater than current renewable energy demand. Thirdly, we evaluate the level and timescale of R&D investment needed to produce the required quantity of carbon-free power by the 2050 timeframe. Fourth, we evaluate the energy potential of various renewable energy resources to ascertain which resources are adequately available globally to support the projected demand. Fifth, we evaluate the challenges to the chemical sciences to enable the cost-effective production of carbon-free power required. Finally, we discuss the effects of a change in primary power technology on the energy supply infrastructure and discuss the impact of such a change on the modes of energy consumption by the energy consumer and additional demands on the chemical sciences to support such a transition in energy supply.

  12. Towards sustainable energy systems: The related role of hydrogen

    Hennicke, Peter; Fischedick, Manfred

    2006-01-01

    The role of hydrogen in long run sustainable energy scenarios for the world and for the case of Germany is analysed, based on key criteria for sustainable energy systems. The possible range of hydrogen within long-term energy scenarios is broad and uncertain depending on assumptions on used primary energy, technology mix, rate of energy efficiency increase and costs degression ('learning effects'). In any case, sustainable energy strategies must give energy efficiency highest priority combined with an accelerated market introduction of renewables ('integrated strategy'). Under these conditions hydrogen will play a major role not before 2030 using natural gas as a bridge to renewable hydrogen. Against the background of an ambitious CO 2 -reduction goal which is under discussion in Germany the potentials for efficiency increase, the necessary structural change of the power plant system (corresponding to the decision to phase out nuclear energy, the transformation of the transportation sector and the market implementation order of renewable energies ('following efficiency guidelines first for electricity generation purposes, than for heat generation and than for the transportation sector')) are analysed based on latest sustainable energy scenarios

    Full Text Available Energy efficiency, renewable energy sources, and environmental protection projects play a pivotal role in tourism. The World Tourism Organization (UNWTO addresses resource management and energy use as one of the major issues. The main goal of the paper is to present the economic–financial analysis and the assessment of investment projects in the construction of a conventional mid-size hotel using fossil fuels and a mid-size hotel based on sustainable principles and renewable energy sources. Comparative analysis of conventional and energy efficient hotels is used to calculate the key financial indicators in decision making. Case study shows that the introduction of renewable energy sources meets the needs of modern guests and increases the hotel's competitiveness, while the effects of energy sustainability reflect on the environment and reduced CO2 emissions. Based on the results, the paper suggests measures for improving energy sustainability in hotels and other tourism facilities. The paper is intended for those who deal with theoretical and practical issues of energy sustainability in tourism, tourism certificates, renewable energy sources and investment costs―scientists, researchers, PhD candidates and students as a basis for further comparative studies and benchmarking. It can also be useful for a considerably wider circle of users―managers at all levels and other business decision makers, as well as proprietors, investors, and creditors.

    Khan, A.; Rogner, H.H.; Aslanian, G.

    2000-01-01

    A project on 'Indicators for Sustainable Energy Development (ISED)' was introduced by the IAEA as a part of its work programme on Comparative Assessment of Energy Sources for the biennium 1999-2000. It is being pursued by the Planning and Economic Studies Section of the Department of Nuclear Energy. The envisaged tasks are to: (1) identify the main components of sustainable energy development and derive a consistent set of appropriate indicators, keeping in view the indicators for Agenda 21, (2) establish relationship of ISED with those of the Agenda 21, and (3) review the Agency's databases and tools to determine the modifications required to apply the ISED. The first two tasks are being pursued with the help of experts from various international organizations and Member States. In this connection two expert group meetings were held, one in May 1999 and the other in November 1999. The following nine topics were identified as the key issues: social development; economic development; environmental congeniality and waste management; resource depletion; adequate provision of energy and disparities; energy efficiency; energy security; energy supply options; and energy pricing. A new conceptual framework model specifically tuned to the energy sector was developed, drawing upon work by other organizations in the environmental area. Within the framework of this conceptual model, two provisional lists of ISED - a full list and a core list - have been prepared. They cover indicators for the following energy related themes and sub-themes under the economic, social and environmental dimensions of sustainable energy development: Economic dimension: Economic activity levels; End-use energy intensities of selected sectors and different manufacturing industries; energy supply efficiency; energy security; and energy pricing. Social dimension: Energy accessibility and disparities. Environmental dimension: Air pollution (urban air quality; global climate change concern); water

    2005-01-01

    Given the importance of energy issues to sustainable development, energy was a priority issue at the World Summit on Sustainable Development in August 2002. The objective of this paper is to examine the outcomes of the Summit on energy, and to assess them against proposals to address the lack of access to modern energy and the need to move toward a cleaner energy system. We find that lack of political leadership from key countries prevented agreement not only on targets for renewable energy, but also on a programme to promote access. The achievements of the Summit were limited to enabling activities such as capacity building and technology transfer, rather than substantive agreements. While WSSD put energy higher on the agenda than before, no institutional home or programme to take the issues forward has emerged. This therefore remains a critical challenge to be addressed. Achieving this broad goal will require building a coalition to promote cleaner energy, and committing resources to programme for energy access. Based on analysis of proposals and the negotiations, we propose several key areas where progress is still possible and necessary, including: shifting more international public and private energy financing toward access investments and cleaner energy investments, advancing regional approaches to access and renewable energy targets, and a range of mechanisms to strengthen institutional capacity for integrating energy and sustainable development

  3. Electricity. The answer to sustainable energy needs

    Bulcke, J.

    1996-01-01

    When debating the rational use of energy, it very often happens that all attention is drawn to the reduction of the use of electricity. Limiting, even eliminating the application of electric heating is seen as a rational choice. On the other hand, industrial consumers are urged to invest in combined heat and power, even without considering a thorough analysis of energy usage. Mastering such an environment is today's challenge for the electricity producers and distributors. Considering the fact that, for a majority of customers, the cost of electricity is more important than the cost of other energy sources, products and services has been developed which, lead to lower bills and lower energy use. From a marketing point of view, this approach introduces electro-thermy to the consumer thereby securing the electricity company of durable sales and even increases in sales. The high efficiency of electrothermal applications secures a reduction in primary energy use. (author)

    2010-01-01

    Energy security issues and climate change are two of the most pressing problems facing society and both of these problems are likely to increase energy price variability in the coming years. This paper develops and estimates a model of a company's energy price exposure and presents evidence showing that increases in a company's environmental sustainability lowers its energy price exposure. This result is robust across two different measures of energy prices. These results should be useful to companies seeking new ways of addressing energy price risk as well as governments concerned about the impact that energy price risk can have on economic growth and prosperity.

    In Pakistan, about two-thirds of the primary energy requirements are met through conventional sources while traditional biomass accounts the remaining one-third The primary commercial energy is largely based on fossil fuels. Indigenous reserves of oil and gas are limited and the coal available in the country is of poor quality. Environmental pollution and greenhouse gas emissions from energy use are becoming significant environmental issues in the country. Achieving solutions to these environmental problems requires long-term potential actions for sustainable development. In this regard, renewable energy resources appear to be one of the most efficient and effective solutions. Pakistan's geographical location has several advantages for extensive use of most of these renewable energy sources. This paper presents review of the present energy situation and environmental sustainability, and assesses the potential of renewable energy sources in Pakistan. Also, potential solutions to current environmental problems are identified along with renewable energy technologies. Several problems relating to renewable energy sources, environmentally sustainable development are discussed from both current and future perspectives. The present study shows that there is substantial potential of renewables in Pakistan. For achieving environmentally sustainable development, renewables must be developed and utilized. (author)

    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.

    The energy issue is now a worldwide concern. It is showed that nuclear energy combined with renewable energies are the only efficient response to face the challenge of climate warming by cutting drastically the emission of greenhouse gases in the electricity production. The second asset of nuclear energy is to be able to meet the growing need for electric power of developing countries. Energy conservation is a good thing to do in western countries but it is far to be sufficient. The success of France's nuclear energy program has enabled the country to be independent from other countries concerning its electricity production, to produce electricity at moderate and stable costs even on the long term, and to develop nuclear industry operators that are world leaders. According to the 28 june 2006 bill that clarifies the management of radioactive wastes, the disposal of high-level radioactive wastes in deep geological layers, will be put into service in 2025. The law has let the possibility of recovering the waste containers during a certain period after their burial if new solutions will have emerged. In the context of an expected renaissance of nuclear energy, the EPR (European Pressurized Reactor) is a valuable offer that must be developed. The construction of an EPR unit on the Flamanville site is necessary to perfect its design. (A.C.)

    In this paper, the author reviewed the energy management activities, over the last two years, of Petroleos Mexicanos, also known as Pemex. These activities generated substantial savings. A brief overview of Pemex was provided. The State Oil Company of Mexico, Pemex occupies the third rank of the world oil producers, and is in seventh place in terms of proven reserves. The gas production has earned the company the ninth spot, and it is in tenth place as far as its refining capacity is concerned. Pemex has annual revenues of 50, 000 million American dollars and operates in excess of 1,000 facilities. The energy management program implemented covered an experts network, training, campaigns, and information and monitoring system. Each of the components of the energy management system were reviewed. Linking each facility, the experts network was created to enhance the efficient use of energy. The Energy Saving and Environmental Protection campaign was held over the period 1999-2000 and involved the participation of 209 work sites. For its part, the Energy Efficient Use and Savings campaign took place in 2000-2001, involving 205 work sites. Both resulted in substantial savings. An internal carbon dioxide trading system was also implemented to improve air quality, and was designed to provide a cap and trade carbon dioxide emissions. The next phase involved the implementation of an information and monitoring system, which defined an Energy Consumption Index used in monthly reports. The next steps in the process were briefly outlined. 5 figs

    Nuclear power currently produces over 628 M tep of the generated energy in 1997 avoiding about 1978 Mt of CO 2 emission and gives a significant contribution to reducing greenhouse gas emission. The competitive position of nuclear power might be strengthened, if market forces or government policy were able to give energy security and to control greenhouse gas, relying upon market mechanism and including environmental costs in economic analysis. In this case, taking into account the entire up-stream and down-stream chains for electricity generation, it can be seen that the greenhouse emission from nuclear plants, is lower than that of renewable energy chains. This paper investigates the potential role of nuclear power in global energy supply up to 2020 and analyzes the opportunities and the challenges for research, governments and nuclear industries of a broad nuclear power development in response to environmental concerns. The authors think that nuclear energy will have to compete in the same framework and under the same conditions as all other energy sources and so analyze the possibility of re-launching nuclear energy: it will have to couple nuclear safety and economic competitiveness [it

    2011-01-01

    Energy autarky is presented as a conceptual framework for implementing sustainable regional development based on the transformation of the energy subsystem. It is conceptualized as a situation in which the energy services used for sustaining local consumption, local production and the export of goods and services are derived from locally renewable energy resources. Technically, the implementation of higher degrees of energy autarky rests on increasing energy efficiency, realizing the potential of renewable energy resources and relying on a decentralized energy system. Practically, a transition towards regional energy autarky requires administrations and civil society actors to initialize and develop projects at the local level, ensure their acceptance and support by the regional population and implement the project in collaboration with relevant actors. Besides the description of the concept and the benefits its implementation brings, this article provides a process for implementation, and some examples from Austria, Germany and Switzerland. - Highlights: → We introduce energy autarky as a conceptual framework for sustainable development. → Transforming the energy subsystem creates various benefits for communities. → Local participation should lead to social acceptance of renewables. → We review and discuss projects implementing energy autarky. → Further research needs to compare successful implementations with failures.

    Nuclear fission energy can deliver safe, sustainable, competitive and practically carbon-free energy to Europe's citizens and industries. Within the framework of the Strategic Energy Technology Plan (SET Plan), the European Commission's stakeholders in this field have formulated a collective vision of the contributions this energy could make towards Europe's transition to a low-carbon energy mix by 2050, with the aim of integrating and expanding R and D capabilities in order to further this objective. The groundwork has been prepared by the stakeholders listed in Annex II, within the framework of two EURATOM FP6 (Sixth Framework Programme) Coordination Actions, namely SNF-TP (Sustainable Nuclear Fission Technology Platform) and PATEROS (Partitioning and Transmutation European Road-map for Sustainable Nuclear Energy), with contributions from Europe's technical safety organisations. This vision report prepares the launch of the European Technology Platform on Sustainable Nuclear Energy (SNE-TP). It proposes a vision for the short-, medium- and long-term development of nuclear fission energy technologies, with the aim of achieving a sustainable production of nuclear energy, a significant progress in economic performance, and a continuous improvement of safety levels as well as resistance to proliferation. In particular, this document proposes road-maps for the development and deployment of potentially sustainable nuclear technologies, as well as actions to harmonize Europe's training and education, whilst renewing its research infrastructures. Public acceptance is also an important issue for the development of nuclear energy. Therefore, research in the fields of nuclear installation safety, protection of workers and populations against radiation, management of all types of waste, and governance methodologies with public participation will be promoted. The proposed road-maps provide the backbone for a strategic research agenda (SRA) to maintain Europe's leadership in

    This study evaluates the sustainability of various farming systems, namely (1) sugarcane on organic and mineral soils and (2) energycane and sweet sorghum on mineral soils. The primary objective of the study is to compare the relative sustainability matrices of these energy crops and their respective farming systems. These matrices should guide decision and policy makers to determine the overall sustainability of an intended or proposed bioethanol project related to any of these studied crops. Several different methods of energy analysis have been proposed to assess the feasibility or sustainability of projects exploiting natural resources (such as (Life Cycle Analysis, Energy Analysis, Exergy Analysis, Cost Benefit Analysis, Ecological Footprint, etc.). This study primarily focused on the concept of Emergy Analysis, a quantitative analytical technique for determining the values of nonmonied and monied resources, services and commodities in common units of the solar energy it took to make them. With this Emergy Analysis study, the Hendry County Sustainable Biofuels Center intends to provide useful perspective for different stakeholder groups to (1) assess and compare the sustainability levels of above named crops cultivation on mineral soils and organic soils for ethanol production and (2) identify processes within the cultivation that could be targeted for improvements. The results provide as much insight into the assumptions inherent in the investigated approaches as they do into the farming systems in this study.

    2010-01-01

    Most of the studies on the Indian energy sector focus on the possible future scenarios of Indian energy system development without considering the management dimension to the problem-how to ensure a smooth transition to reach the desired future state. The purpose of this paper is to highlight some sector management concerns to a sustainable energy future in the country. The paper follows a deductive approach and reviews the present status and possible future energy outlooks from the existing literature. This is followed by a strategy outline to achieve long-term energy sustainability. Management challenges on the way to such a sustainable future are finally presented. The paper finds that the aspiration of becoming an economic powerhouse and the need to eradicate poverty will necessarily mean an increase in energy consumption unless a decoupling of energy and GDP growth is achieved. Consequently, the energy future of the country is eminently unsustainable. A strategy focussing on demand reduction, enhanced access, use of local resources and better management practices is proposed here. However, a sustainable path faces a number of challenges from the management and policy perspectives.

    The application of taxes is said to be a valuable means of solving environmental problems; provision of the right incentives will invariably achieve the goal. The policy requirements for addressing the environmental problems are (i) to understand and accept a vision of a sustainable future; (ii) to understand the nature of the challenge; (iii) decide a course of action for the desired future and (iv) the will to implement the actions. The subject is discussed under the sub-headings of (a) The Government Approach; (b) The Climate Change Levy; (c) The Future (short, medium and long term); (d) Recommendations and (e) Renewable Technologies. The potential for carbon savings through a market led transition to a low carbon economy is 'extensive'. The Government must have regulation, taxation or legislation to shape the market to lead to a socially desirable outcome

    Energy, a major contributor to development, is an essential element for increasing quality of life. During the next decades, the developing world will experience an explosive increase of energy demand, requiring enormous efforts and ingenuity to be fully satisfied. Delays may create public frustration for not achieving paradigm levels of quality of life, giving eventually rise to serious pressures on governments. The concept of sustainable energy options for development cannot be analyzed under the same prism in developed and developing countries. The relative degree of a country development should be introduced when setting up the path to sustainable development. (author)

  10. Biomass in a sustainable energy system

    International Nuclear Information System (INIS)

    Boerjesson, Paal

    1998-04-01

    In this thesis, aspects of an increase in the utilization of biomass in the Swedish energy system are treated. Modern bioenergy systems should be based on high energy and land use efficiency since biomass resources and productive land are limited. The energy input, including transportation, per unit biomass produced is about 4-5% for logging residues, straw and short rotation forest (Salix). Salix has the highest net energy yield per hectare among the various energy crops cultivated in Sweden. The CO 2 emissions from the production and transportation of logging residues, straw and Salix, are equivalent to 2-3% of those from a complete fuel-cycle for coal. Substituting biomass for fossil fuels in electricity and heat production is, in general, less costly and leads to a greater CO 2 reduction per unit biomass than substituting biomass derived transportation fuels for petrol or diesel. Transportation fuels produced from cellulosic biomass provide larger and less expensive CO 2 emission reductions than transportation fuels from annual crops. Swedish CO 2 emissions could be reduced by about 50% from the present level if fossil fuels are replaced and the energy demand is unchanged. There is a good balance between potential regional production and utilization of biomass in Sweden. Future biomass transportation distances need not be longer than, on average, about 40 km. About 22 TWh electricity could be produced annually from biomass in large district heating systems by cogeneration. Cultivation of Salix and energy grass could be utilized to reduce the negative environmental impact of current agricultural practices, such as the emission of greenhouse gases, nutrient leaching, decreased soil fertility and erosion, and for the treatment of municipal waste and sludge, leading to increased recirculation of nutrients. About 20 TWh biomass could theoretically be produced per year at an average cost of less than 50% of current production cost, if the economic value of these

  13. A SES (sustainable energy security) index for developing countries

    International Nuclear Information System (INIS)

    Narula, Kapil; Reddy, B. Sudhakara

    2016-01-01

    Measuring the performance of the energy system of a country is a prerequisite for framing good energy polices. However, the existing indices which claim to measure energy security have limited applicability for developing countries. Energy sustainability is also increasingly gaining importance and countries are keen to measure it to tailor their energy policies. Therefore, the concept of SES (sustainable energy security) has been proposed as the goal for a developing country. This paper presents an analytical framework for the assessment of SES of an energy system and the methodology for constructing an SES index. A hierarchical structure has been proposed and the energy system has been divided into 'supply', 'conversion & distribution' and 'demand' sub-systems. Each subsystem is further divided into its components which are evaluated for four dimensions of SES, Availability, Affordability, Efficiency and (Environmental) Acceptability using quantitative metrics. Energy indices are constructed using 'scores' (objective values), and 'weights' (subjective values representing tradeoffs) which are then aggregated, bottom-up, to obtain an overall SES Index for a country. The proposed SES Index is multidimensional, quantitative, modular, systemic and flexible. Such a SES Index can be used to design policy interventions for transitioning to a sustainable and a secure energy future. - Highlights: • A SES (sustainable energy security) index is proposed for developing countries. • A hierarchical structure includes the entire energy system from supply to end use. • The performance of all energy sources, energy carriers and sectors is assessed. • Availability, affordability, efficiency and acceptability dimensions are evaluated. • The SES index is multidimensional, quantitative, modular, systemic and flexible.

    Keong, C.Y.

    2005-01-01

    In embarking on a dynamic course of economic development and industrial modernism, Malaysia sees the need to increase its electricity generation capacity through the development of a mega-dam project - the Bakun dam. Although hydroelectricity generation offers one of the benign options in accommodating the increasing energy consumption per capita in Malaysia, it is argued that the construction of Bakun's dam which involves a complete and irreversible destruction of 69,640 ha of old forest ecosystem remains a difficult and uncertain endeavour. It is further argued that apart from mega-dam technology, there are also other means to orchestrate a sustainable energy system in Malaysia. These include the implementation of demand and supply initiatives, such as the deployment of energy saving technology or influencing behavioral change towards a sustainable energy consumption pattern

  15. Designing an EU energy and climate policy portfolio for 2030: Implications of overlapping regulation under different levels of electricity demand

    2014-01-01

    The European Union's current climate and energy policy has to operate under an ex ante unforeseen economic crisis. As a consequence prices for carbon emission allowances in the EU Emissions Trading System collapsed. However, this price collapse may be amplified by the interaction of a carbon emission cap with supplementary policy targets such as minimum shares for renewables in the power sector. The static interaction between climate and renewable policies has been discussed extensively. This paper extends this debate by analysing the efficiency and effectiveness of a policy portfolio containing a cap and trade scheme and a target for a minimum renewable share in different states of aggregate electricity demand. Making use of a simple partial equilibrium model of the power sector we identify an asymmetric interaction of emissions trading and renewable quotas with respect to different states of aggregate electricity demand. The results imply that unintended consequences of the policy interaction may be particularly severe and costly when aggregate electricity demand is low and that carbon prices are more sensitive to changes in economic activity if they are applied in combination with renewable energy targets. Our analysis of the policy interaction focuses on the EU, yet the conclusions may also be of relevance for fast growing emerging economies like China. - Highlights: • A minimum renewable quota that is added to an existing emissions trading system causes excess costs. • Excess costs depend on electricity demand and are highest when electricity demand is low. • Excess costs can reach up to 1.2 Billion Euro annually in the European Union in 2030. • CO 2 prices are more sensitive to changes in electricity demand if combined with minimum renewable quota

  16. Is the German energy transition sustainable?

    International Nuclear Information System (INIS)

    Beeker, Etienne; Godot, Clelia

    2012-09-01

    In 2011, Germany began a radical energy policy, or 'Energiewende', with the aim of completely abandoning nuclear power by 2022 and then achieving an 80-95% reduction in the country's greenhouse gas emissions by 2050. By this date, the country will therefore have to be producing its electricity almost completely without the use of gas, oil and coal, having replaced 80% of these sources with renewable energies. Germany is a rich country with one of the most competitive industries in the world. Its environmental commitments have been clearly stated and Energiewende, which is widely discussed throughout the country, has so far seen strong support from the population, despite the expected increases in the price of electricity which, however, is already almost twice as expensive as in France. Germany therefore seems to hold the winning cards required to successfully implement its energy transition. However, many difficulties need to be overcome if this energy policy is to succeed, such as the development of the national power grid, the cost and financing of the necessary investments, improved electricity storage techniques, the acceptability of the planned increases in the price of electricity or the financial difficulties experienced by solar panel manufacturers as a result of the sharp reduction in subsidies and competition from Asia. In addition, recent political dissent within the government regarding the measures implemented to achieve its stated goal has slowed down the federal decision-making process on this matter. Finally, Germany's decision is not without consequences for its European neighbours. It is upsetting and weakening the supply and demand balance of the European energy system and putting some operators in a difficult position. The eyes of all energy world observers are therefore riveted on the changes taking place in Germany, because they will have significant consequences for the entire European Union, and even beyond.

    Pakistan is an energy deficient country that heavily relies on imports of fossil fuels to meet its energy requirements. Pakistan is facing severe energy challenges -indigenous oil and gas reserves are running out, energy demand is rapidly increasing, gap between demand and supply is growing, concerns about secure supply of energy are increasing and fuel cost is rising at an unprecedented rate. For sustainable development, it is crucial to ensure supply of adequate, consistent and secure supply of energy. Renewable energy resources that are sustainable are abundantly available in Pakistan in various forms such as hydel power, solar energy, wind power and biomass. To address the growing energy challenges, it has become inevitable for the country to diversify its energy market through harnessing renewable energy resources. It has been found that hydel power is one of the most significant renewable energy sources that can help Pakistan address the present as well as future energy challenges. It has been identified that solar water heating is another ready to adopt renewable energy technology that alone has the potential to meet as much as 12-15% of the country's entire energy requirements.

    Traditional village houses now use renewable materials and energy sources and this paper presents the intrinsic harmony of these buildings' greening and their sustainability. The paper covers building technical systems, sustainable energy supply, and the importance of renewable raw materials (RMS) for sustainable development. This study investigated the role of building dynamic behavior and optimized energy efficiency in reducing thermal loads significantly. A preliminary design for sustainable energy efficient settlements with net zero energy buildings is proposed and a comprehensive multidisciplinary engineering study was done which identified the technical feasibility of sustainable village energy and water supplies using solar or wind technologies. Overall, through analysis of sustainability definitions and possible ways to achieve sustainability, the study demonstrated that this can only be brought about by interdisciplinary interaction and finding the right balance between materiality and spirituality, science and art, and between technological development and concern for cultural and other human values.

    The article presents the results of a complex experimental-analytical research of residential development energy parameters - survey of construction sites and determination of calculated energy parameters (resistance to heat transfer) considering their technical condition. The authors suggest a methodology for assessing residential development energy parameters on the basis of construction project's structural analysis with the use of advanced intelligent collection systems, processing (self-organizing maps - SOM) and data visualization (geo-informational systems - GIS). SOM clustering permitted to divide the housing stock (on the example of Arkhangelsk city) into groups with similar technical-operational and energy parameters. It is also possible to measure energy parameters of construction project of each cluster by comparing them with reference (normative) measures and also with each other. The authors propose mechanisms for increasing the area's energy stability level by implementing a set of reproduction activities for residential development of various groups. The analysis showed that modern multilevel and high-rise construction buildings have the least heat losses. At present, however, ow-rise wood buildings is the dominant styles of buildings of Arkhangelsk city. Data visualisation on the created heat map showed that such housing stock covers the largest urban area. The development strategies for depressed areas is in a high-rise building, which show the economic, social and environmental benefits of upward growth of the city. An urban regeneration programme for severely rundown urban housing estates is in a high-rise construction building, which show the economic, social and environmental benefits of upward growth of the city.

    Since this year there can be no doubt that "sustainability" has become the top issue in the automotive sector. Volkswagen's CEO Prof. Dr. Martin Winterkorn attacked incumbents like BMW Group (so far the "most sustainable car manufacturer" for the 8th consecutive year) or Toyota (producer of the famous "Prius") head-on by boldly stating to become "the most profitable and most sustainable car manufacturer worldwide by 2018" . This announcement clearly shows that "sustainability" and "profitability" no longer are considered as conflicting targets. On the contrary, to Prof. Dr. Winterkorn : "climate protection is a driver for economic growth". To prime discussions, the plenary talk will give a brief overview of the entire range of energy efficiency in the automotive sector: based on the multiple drivers behind energy efficiency, practical examples are presented along the entire life-cycle of cars (R&D, production, usage and recycling). These "cases" include big automobile producers as well as their respectiv...

    In view of having a still unexploited potential of natural resources available for clean energy and the possibility of using the regional electricity market in Central America, Honduras has several potential energy sources. The growing dependence on oil and the imminent increase in international prices of fossil fuels, coupled with the necessity of changing the energy sector arrangement, the State of Honduras has taken the lead for the development of a long-term sustainable energy policy.

  7. Operationalizing Sustainable Development Suncor Energy Inc: A critical case

    Science.gov (United States)

    Fergus, Andrew

    The concept of Sustainable Development is often understood as a framework within which organizations are able to move forward in a successful and beneficial manner. However, it is also seen as an ambiguous notion with little substance beyond a hopeful dialogue. If we are to base organizational action upon the concepts of Sustainable Development, it is vital that we comprehend the implications of how the concept is understood at a behavioral level. Industry leaders, competitors, shareholders, and stakeholders recognize Suncor Energy Inc as a leading organization within the Oil and Gas energy field. In particular it has a reputation for proactive thinking and action within the areas of environmental and social responsibility. Through attempting to integrate the ideas of Sustainable Development at a foundational level into the strategic plan, the management of Suncor Energy Inc has committed the organization to be a sustainable energy company. To achieve this vision the organization faces the challenge of converting strategic goals into operational behaviors, a process critical for a successful future. This research focuses on understanding the issues found with this conversion process. Through exploring a critical case, this research illuminates the reality of a best-case scenario. The findings thus have implications for both Suncor Energy Inc and more importantly all other organizations attempting to move in a Sustainable Development direction.

    During the last 50 years or so there is enormous development in various fields like agriculture, industry, medicine, etc. Further, the population on this globe has increased many folds. In order to cater to the needs of the present population there is an increasing demand of electricity in the society. Per capita electricity consumption also is an index of development in the country. Considering the facts like green house effect and global warming, nuclear energy is the better option. But at the same time there are some critical issues like nuclear waste management globally and availability of fissile material in the context of our country. Research and development are going on to take care of these issues where scientists and engineers are working on alternative fuel cycle and new reactor types, for example Accelerator Driven Subcritical (ADS) System is one of them. Since, ADS reactor is a subcritical system, safety related issues are in fact of low concern relative to existing critical reactors. As a matter of fact, the ADS system is the combination of a particle accelerator and a nuclear reactor. In this talk, a detailed description of the need of energy in our country, which can only be met if nuclear energy contributes a substantial energy requirement, will be presented. Further, how the nuclear waste management issues may be addressed, with the new ADS system will also be presented. (author)

    2009-01-01

    When viewed from a large set of criteria such as abundance of energy resources, environmental impacts, low fuel inventory, quantum of waste generated and green house gas emissions, nuclear power can be considered as a large scale sustainable energy source. Among all energy sources, nuclear energy has perhaps the lowest impact on the environment, especially in relation to kilowatt-hr produced, because nuclear plants do not emit harmful gases and produce small quantity of waste. In other words, nuclear energy is the most environmental friendly electricity source. There are no significant adverse effects to water, land, habitat, species and air resources. The present paper discusses the sustainability and feasibility of nuclear power as an eco friendly energy source in the changing and challenging competitive power market. (author)

    The VROM Council offered to host a workshop (27-28 October 2000) for a group of European environmental advisory bodies. This meeting is meant as a kick-off for a working group on energy and climate change. The workshop may help to develop standpoints of the advisory bodies on the basis of shared knowledge of problem perceptions and proposed solutions in other EU countries. This may increase the common denominator and thus promote common EU policies. The proposed title for this workshop is: Reconciling a sustainable energy future with the liberalisation and privatisation of the European energy market One of the participating councils from each country is expected to draft a report on the policies directed at a sustainable energy future in their respective countries. These reports should include the following elements of the national policies and relevant proposals of the councils: a brief description of the current energy supply and a lookout on sustainable development in the energy sector; .a description of the liberalisation and privatisation of the energy market, including the institutional reform (government involvement), juridical changes and realisation path and, if applicable, how the share of non fossil energy generation is enlarged; a description of how in the future a sustainable energy supply will be promoted, including (options for) policy strategies, measures and instruments; and a description of the European Union (EU) policy that is conditional for the realisation of these national policies. The VROM Council has asked CE to produce the report for the Netherlands. The report is organised as follows. Chapter 2 gives a brief description of the current Dutch energy and CO2 characteristics. Chapter 3 gives an overview of Dutch energy policy and chapter 4 an overview of Dutch climate policy. The chapters 5-7 give the views of the various councils on energy and climate policy (AER, VROMRaad, and SER). The final chapter, chapter 8, gives some suggestions for

    Zhang, Na; Lior, Noam; Jin, Hongguang

    2011-01-01

    The paper briefly summarizes China's energy situation and sustainable development strategy as they were by 2009. The energy consumption in 2009 is reported to be 3.1 billion tons standard coal equivalent, 1/7 of the world total, 6.3% higher than in the year 2008, and its share of world CO 2 emissions increased rapidly to 20.3% in 2006. These trends are most likely to continue with China's plan to accomplish its social and economy development goals. To address these problems and also respond to increasing world pressure for reduction of greenhouse gas emissions, the Chinese government plans and has legislated promotion of energy conservation, efficiency, renewable energy technologies and use, and reduction of energy-related environmental impacts to reduce energy intensity by 20% during the 2006-2010 period, and to reduce the CO 2 emission/GDP ratio by 40-45% by 2020 relative to 2005. China is facing severe energy-related challenges that conflict resources shortages with the planned rapid economic development, energy use with the related environmental pollution, and new technology with the old production/consumption patterns. It is recognized that energy development must, however, follow a sustainable path to coordinate economy growth, social development, and environmental protection. -- Highlights: → A brief summary of China's energy situation and plans in 2009; → Energy consumption and CO 2 emissions are likely to continue rising; → China to reduce energy intensity, and the (CO 2 emission)/GDP ratio by 40-45% by 2020; → Energy-related challenges and desired sustainable development strategy are discussed; → The strategy core is energy conservation and non-fossil fuel energy development.

    The United Nations Conference of Environment and Development has focused the world's attention on the complex relationship between the environment and economic development. The essence of this relationship, and the emerging theme of UNCED, is the concept of sustainability. Sustainable economic development improves quality of life and raises standards of living by using the Earth's resources in a way that ensures that they are continually renewed, and will continue to support future generations. This is the subject of this report. While energy resources are essential to economic development, the authors current patterns of energy use are not sustainable. Reliance on fossil fuels, nuclear energy, and large-scale hydroelectric projects has contributed to serious environmental problems, including atmospheric pollution, loss of land productivity, loss of biological diversity, ocean and fresh water pollution, and hazardous waste generation. Thus, if they are to achieve sustainability in their patterns of energy consumption, it is imperative that they bring about a rapid and widespread transition to the utilization of environmentally sound energy sources and technologies. Solar energy technologies are environmentally sound, socially beneficial, and economically practical. They have been proven in a wide variety of applications around the world. The barriers to the widespread implementation of solar technologies are no longer technical, but rather social, economic, and political. These barriers can and must be removed

  5. Sustainable business models for wind and solar energy in Romania

    2015-06-01

    Full Text Available Renewable energy has become a crucial element for the business environment as the need for new energy resources and the degree of climate change are increasing. As developed economies strive towards greater progress, sustainable business models are of the essence in order to maintain a balance between the triple bottom line: people, planet and profit. In recent years, European Union countries have installed important capacities of renewable energy, especially wind and solar energy to achieve this purpose. The objective of this article is to make a comparative study between the current sustainable business models implemented in companies that are active in the wind and solar energy sector in Romania. Both sectors underwent tremendous changes in the last two years due to changing support schemes which have had a significant influence on the mechanism of the renewable energy market, as well as on its development. Using the classical Delphi method, based on questionnaires and interviews with experts in the fields of wind and solar energy, this paper offers an overview of the sustainable business models of wind and solar energy companies, both sectors opting for the alternative of selling electricity to trading companies as a main source of revenue until 2013 and as the main future trend until 2020. Furthermore, the participating wind energy companies noted a pessimistic outlook of future investments due to legal instability that made them to reduce their projects in comparison to PV investments, which are expected to continue. The subject of the article is of interest to scientific literature because sustainable business models in wind and photovoltaic energy have been scarcely researched in previous articles and are essential in understanding the activity of the companies in these two fields of renewable energy.

    To prepare for an urban influx of 2.5 billion people by 2050, it is critical to create cities that are low-carbon, resilient, and livable. Cities not only contribute to global climate change by emitting the majority of anthropogenic greenhouse gases but also are particularly vulnerable to the effects of climate change and extreme weather. We explore options for establishing sustainable energy systems by reducing energy consumption, particularly in the buildings and transportation sectors, and providing robust, decentralized, and renewable energy sources. Through technical advancements in power density, city-integrated renewable energy will be better suited to satisfy the high-energy demands of growing urban areas. Several economic, technical, behavioral, and political challenges need to be overcome for innovation to improve urban sustainability.

    Highlights: • Clean cookstoves that also generate electricity improve affordability. • Excel spreadsheet model to assist stakeholders to choose optimum technology. • Presents views for each stakeholder villager, village and country. • By adding certain capital costs, affordability and sustainability are improved. • Affordability is highly dependent on carbon credits and social understandings. - Abstract: Clean burning products, for example cooking stoves, can reduce household air pollution (HAP), which prematurely kills 3.5 million people each year. By careful selection of components into a product package with micro-finance used for the capital payment, barriers to large-scale uptake of products that remove HAP are reduced. Such products reduce smoke from cooking and the lighting from electricity produced, eliminates smoke from kerosene lamps. A bottom-up financial model, that is cognisant of end user social needs, has been developed to compare different products for use in rural areas of developing countries. The model is freely available for use by researchers and has the ability to assist in the analysis of changing assumptions. Business views of an individual villager, the village itself and a country view are presented. The model shows that affordability (defined as the effect on household expenses as a result of a product purchase) and recognition of end-user social needs are as important as product cost. The effects of large-scale deployment (greater that 10 million per year) are described together with level of subsidy required by the poorest people. With the assumptions given, the model shows that pico-hydro is the most cost effective, but not generally available, one thermo-acoustic technology option does not require subsidy, but it is only at technology readiness level 2 (NASA definition) therefore costs are predicted and very large investment in manufacturing capability is needed to meet the cost target. Thermo-electric is currently the only

    The status and role of nuclear energy in the sustainable energy development strategy in China are discussed in this research report. Specifically, the role of nuclear energy in meeting the requirements of energy and electricity supply, environment protection and greenhouse gas (GHG) emission-reduction is focused on. The report is mainly composed of three component parts. The serious situation and challenges concerning the national energy security and energy sustainable development, and major tasks proposed to carry out the strategy of energy sustainable development are expounded in the first part. In the second part, the position and role of nuclear energy in China are elaborated and analyzed in detail. Firstly, it is indicated that the development of nuclear energy is the objective requirement for optimizing national energy structure. From the viewpoint of climate and environment protection, energy mix is required to transit from conventional fossil fuels to clean and high-quality energy sources. The potential role of nuclear energy in energy structure optimization in China is compared with that of hydro and other renewable energy sources. Secondly, it is proposed that the development of nuclear energy is the important security option for safely supplying the national energy and electricity in the future, mainly from the point of nuclear power providing stable and reliable power supply, relieving the burden of coal exploitation and transportation and reducing the risk of energy security caused by dependence on oil and natural gas. Thirdly, it is elaborated that the development of nuclear energy is the inevitable selection for carrying out the national energy and electricity sustainable development. It is given further details that nuclear energy is a clean and economical energy option, a preference coinciding with the principles of the circular economy, a feasible technical choice to greatly reduce emission of greenhouse gases, a selection contributing to

The successful completion of this work is the result of an intensive effort led by the International Atomic Energy Agency (IAEA) in cooperation with the United Nations Department of Economic and Social Affairs (UNDESA), the International Energy Agency (IEA), Eurostat and the European Environment Agency (EEA). The thematic framework, guidelines, methodology sheets and energy indicators set out in this publication reflect the expertise of these various agencies, recognized worldwide as leaders in energy and environmental statistics and analysis. While each agency has an active indicator programme, one goal of this joint endeavour has been to provide users with a consensus by leading experts on definitions, guidelines and methodologies for the development and worldwide use of a single set of energy indicators. No set of energy indicators can be final and definitive. To be useful, indicators must evolve over time to fit country-specific conditions, priorities and capabilities. The purpose of this publication is to present one set of EISD for consideration and use, particularly at the national level, and to serve as a starting point in the development of a more comprehensive and universally accepted set of energy indicators relevant to sustainable development. It is hoped that countries will use the EISD to assess their energy systems and to track their progress towards nationally defined sustainable development goals and objectives. It is also hoped that users of the information presented in this publication will contribute to refinements of energy indicators for sustainable development by adding their own unique perspectives to what is presented herein

    Consider a family of portfolio strategies with the aim of achieving the asymptotic growth rate of the best one. The idea behind Cover's universal portfolio is to build a wealth-weighted average which can be viewed as a buy-and-hold portfolio of portfolios. When an optimal portfolio exists, the wealth-weighted average converges to it by concentration of wealth. Working under a discrete time and pathwise setup, we show under suitable conditions that the distribution of wealth in the family sati...

    Company, which wants to be successful in an open market, must continuously improve its existing production capacities taking into account competitiveness - by improving safety and reliability, minimising the risk of damages and losses due to unplanned outages.. At the same time the company has to optimise operation, e.g. by shortening of the planned outages, decreasing emissions and waste, water and fuel consumption, automatisation as well as using the reserves of existing production equipment. Based on the last mentioned example the company Slovenske elektrarne is an excellent company, which after the shut down of unit 1 in the state-owned V1 Bohunice NPP, was able to deliver 150 MWe of new capacity to the grid in the period 2008- 2009 (or 180 MWe by 2010), and thus increase energy security in Slovakia.

    2014-01-01

    Several recent studies have proposed fast transitions to energy systems based on renewable energy technology. Many of them dismiss potential physical constraints and issues with natural resource supply, and do not consider the growth rates of the individual technologies needed or how the energy systems are to be sustained over longer time frames. A case study is presented modelling potential growth rates of the wind energy required to reach installed capacities proposed in other studies, taking into account the expected service life of wind turbines. A sustained commissioning model is proposed as a theoretical foundation for analysing reasonable growth patterns for technologies that can be sustained in the future. The annual installation and related resource requirements to reach proposed wind capacity are quantified and it is concluded that these factors should be considered when assessing the feasibility, and even the sustainability, of fast energy transitions. Even a sustained commissioning scenario would require significant resource flows, for the transition as well as for sustaining the system, indefinitely. Recent studies that claim there are no potential natural resource barriers or other physical constraints to fast transitions to renewable energy appear inadequate in ruling out these concerns. - Highlights: • Growth rates and service life is important when evaluating energy transitions. • A sustained commissioning model is suggested for analysing renewable energy. • Natural resource requirements for renewable energy are connected to growth rates. • Arguments by recent studies ruling out physical constraints appear inadequate

    The Energy [R]evolution 2008 scenario is an update of the Energy [R]evolution scenario published in 2007. It takes up recent trends in global socio-economic developments, and analyses to which extent they affect chances for achieving global climate protection targets. The main target is to reduce global CO 2 emissions to 10 Gt per year in 2050, thus limiting global average temperature increase to 2 deg. C and preventing dangerous anthropogenic interference with the climate system. A review of sector and region specific energy efficiency measures resulted in the specification of a global energy demand scenario incorporating strong energy efficiency measures. The corresponding energy supply scenario has been developed in an iterative process in close cooperation with stakeholders and regional counterparts from academia, NGOs and the renewable energy industry. The Energy [R]evolution scenario shows that renewable energy can provide more than half of the world's energy needs by 2050. Developing countries can virtually stabilise their CO 2 emissions, whilst at the same time increasing energy consumption through economic growth. OECD countries will be able to reduce their emissions by up to 80%.

    A high current Nordic competence in energy technology and an increased need for funding and international cooperation in the field are the main messages of the report. This report summarizes results from 7 different research projects relating to policies for energy technology, funded by Nordic Energy Research for the period 2007-2008, and provides an analysis of the Nordic innovation systems in the energy sector. The Nordic countries possess a high level of competence in the field of renewable energy technologies. Of the total installed capacity comprises a large share of renewable energy, and Nordic technology companies play an important role in the international market. Especially distinguished wind energy, both in view of the installed power and a global technology sales. Public funding for energy research has experienced a significant decline since the oil crisis of the 1970s, although the figures in recent years has increased a bit. According to the IEA, it will require a significant increase in funding to reduce greenhouse gas emissions and limit further climate change. The third point highlighted in the report is the importance of international cooperation in energy research. Nordic and international cooperation is necessary in order to reduce duplication and create the synergy needed if we are to achieve our ambitious policy objectives in the climate and energy issue.

    Developing and promoting a farsighted energy policy is a key aspect in achieving sustainable development in the European Union. Factors to be coped with in this context are the Union's increasing dependence on energy imports, and the threats facing the climate. Moreover, it is imperative that the Lisbon strategy be pursued, according to which Europe is to be made the world's most dynamic knowledge-based economic region by 2010. As early as in 2000, the EU Commission published its Green Paper, ''Towards a European Strategy of Continuity in Power Supply.'' Continuity of supply, in this context, not only stands for maximized self-sufficiency or minimized dependencies. What is at stake is a reduction of the risks stemming from dependence on imports and from changes in the environment. This goal can be achieved through a balanced and diverse structure both of energy resources and of the geographic origins of fuels. The right energy mix is decisive. The European Commission feels that nuclear power can make an important contribution towards sustainable energy supply in Europe. Nuclear power should keep its place in the European energy mix. One important aspect in this regard is improved public acceptance through communication, transparency, and confidence building. High safety standards and a credible approach to the safe long-term management of radioactive waste are major components of this sustainable energy source. (orig.)

    2001-01-01

    This report for the Swiss Federal Office of Energy (SFOE) presents the results of a study made on the concept of sustainability with reference to the energy area. The importance of energy topics in the fundamental ideas behind sustainability - ecological compatibility, economic efficiency and social fairness - is discussed. The methods used to define the criteria and indicators for sustainability are discussed on the basis of existing systems. >From these, criteria and indicators are proposed for the energy area, including indicators for the influence of energy on the environment, economy and society, activity-indicators and indicators for energy efficiency and politics. The system boundaries for the indicators are discussed, as are grey energy and other 'grey' effects in the environmental, economic and social areas. The various criteria, indicators and the effort needed to collect data on them are presented in table form. The report is completed with a discussion of recommendations on what is still to be done in the area, how the results of the study can be used and what actions are still to be taken

    Migrating birds have been able to sustain an energy expenditure (EE) that is five times their basal metabolic rate. Although humans can readily reach these levels, it is not yet clear what levels can be sustained for several days. The study's purposes were 1) to determine the upper limits of human EE and whether or not those levels can be sustained without inducing catabolism of body tissues and 2) to determine whether initial body weight is related to the levels that can be sustained. We compiled data on documented EE as measured by doubly labeled water during high levels of physical activity (minimum of five consecutive days). We calculated the physical activity level (PAL) of each individual studied (PAL = total EE / basal metabolic rate) from the published data. Correlations were run to examine the relationship between initial body weight and body weight lost with both total EE and PAL. The uppermost limit of EE was a peak PAL of 6.94 that was sustained for 10 consecutive days of a 95-d race. Only two studies reported PALs above 5.0; however, significant decreases in body mass were found in each study (0.45-1.39 kg·wk(-1) of weight loss). To test whether initial weight affects the ability to sustain high PALs, we found a significant positive correlation between TEE and initial body weight (r = 0.46, P body weight (r = 0.27, not statistically significant). Some elite humans are able to sustain PALs above 5.0 for a minimum of 10 d. Although significant decreases in body weight occur at this level, catabolism of body tissue may be preventable in situations with proper energy intake. Further, initial body weight does not seem to affect the sustainability of PALs.

    Conventional techniques of economics, in different countries, do not normally take proper account of increases in the cost of energy (especially oil) that are expected in the next twenty years, or the rapidly declining ability of the environment to absorb wastes and pollutants, especially those resulting from the use of fossil fuels. Unless these factors are included in political-economic decision-making, and paths for future development adjusted to take account of them, many future development options will be severely damaged. In this paper, it is argued that new decision-making principles are urgently needed, in which societies accept that the physics of the environment are dominant, and the desires of people are subject to physical constraints. When future development options are considered, there is therefore a hierarchy of decision-making. Primary decisions depend upon the physics and ecology of the environment, of development, and of resource utilization. These have to be made before secondary decisions which are mainly ethical, and depend upon social and community values. These are best expressed by people, through adult education and the political process. Only then is it possible to make tertiary decisions, which relate to the allocation of resources. These decisions will depend heavily upon the use of economic tools. Several approaches have been proposed for improving political-economic decision-making. Some concentrate on modifications to markets, so they can incorporate ''externalities''. In other approaches, physical understandings are introduced into policy analyses, in order to indicate the constraints that limit development options. Some important techniques are reviewed, and suggestions are made about better methods of decision-making in the future. (author)

    Nuclear power has experienced a major boom in the last few years, primarily because it is a non-CO 2 emitting energy source, it can be produced at competitive costs and it can boost a country's security of supply. there are still two issues to be addressed in relation to the currently used technologies: the degree to which the energy content of nuclear fuel is used, and wastes. A solution to both these aspects would ut nuclear power in the category of sustainable energy. The article provides details on current nuclear plans in the wold, the impact of the Fukushima accident on different countries nuclear plans and the European initiatives for sustainable nuclear energy development.

    Biomass is a renewable energy source and its importance will increase as national energy policy and strategy focuses more heavily on renewable sources and conservation. Biomass is considered the renewable energy source with the highest potential to contribute to the energy needs of modern society for both the industrialized and developing countries worldwide. The most important biomass energy sources are wood and wood wastes, agricultural crops and their waste byproducts, municipal solid waste, animal wastes, waste from food processing, and aquatic plants and algae. Biomass is one potential source of renewable energy and the conversion of plant material into a suitable form of energy, usually electricity or as a fuel for an internal combustion engine, can be achieved using a number of different routes, each with specific pros and cons. Currently, much research has been focused on sustainable and environmental friendly energy from biomass to replace conventional fossil fuels. The main objective of the present study is to investigate global potential and use of biomass energy and its contribution to the sustainable energy development by presenting its historical development.

    Modern society is dependent on fossil fuels for its energy needs, but their combustion is producing emissions of greenhouse gases that cause global warming. If these emissions remain unconstrained they risk of producing significant impacts on humanity and ecosystems. Replacement of fossil fuels with alternative energy sources can stabilize anthropogenic global warming and thus reduce the climate change impacts. The deployment of alternative energy supply technologies should be based on objectives that are consistent with sustainability indicators and incorporate quantitative risk assessment multiattribute utility decision methodologies capable of ascertaining effective future energy supply options.

    Sustainable development could be seen as indispensable condition for survival of civilization. Construction sector is a field with immediate need for reducing environmental impacts. Sustainability measures applied for buildings could produce very efficient results to the people. The paper provides the methods of construction sustainability increase by researching, developing, and applying the technologies which use renewable materials and energy. The paper analyzes the cases of both a solar eco house which was built of original prefabricated straw-bale panels and was designed to use direct solar energy; and an educational project promoting straw-bale construction and seeking to mitigate climate change. The project results have shown the need of spreading information on sustainable building methods to be accepted by wider society and to be applied to the construction industry. Monitoring of solar ecohouse has proved that direct solar energy gains are significant in reducing heating degree-days in 55 N latitude and in allowing to save half the energy needed for heating.

    Full Text Available This paper proposes the use of sustainable energy systems based on solar and biomass technologies to provide solutions to utility challenges in Nigeria and acute water shortage both in rural and urban areas of that country. The paper highlights the paradoxes of oil-rich Nigeria and the stark reality of social infrastructure deprivations in that country. Perennial power outages over many years have translated to the absence of or poorly-developed basic social infrastructures in Nigeria. The consequences of this lack have been an increase in abject poverty in rural and urban communities as well as the erosion of social order and threats to citizen and their property. This paper proposes the adaptation of two emerging technologies for building sustainable energy systems and the development of decentralized and sustainable energy sources as catalyst for much-needed social infrastructure development through the creation of Renewable Energy Business Incubators, creative lending strategies, NGO partnerships and shifting energy-distribution responsibilities. These changes will stimulate grassroots economies in the country, develop large quantities of much needed clean water, maintain acceptable standards of sanitation and improve the health and wellbeing of Nigerian communities. The proposed strategies are specific to the Nigerian context; however, the authors suggest that the same or similar strategies may provide energy and social infrastructure development solutions to other developing countries as well.

  10. Limitations of Nuclear Power as a Sustainable Energy Source

    2012-06-01

    Full Text Available This paper provides a review and analysis of the challenges that nuclear power must overcome in order to be considered sustainable. The results make it clear that not only do innovative technical solutions need to be generated for the fundamental inherent environmental burdens of nuclear energy technology, but the nuclear industry must also address difficult issues of equity both in the present and for future generations. The results show that if the concept of just sustainability is applied to the nuclear energy sector a global large-scale sustainable nuclear energy system to replace fossil fuel combustion requires the following: (i a radical improvement in greenhouse gas emissions intensity by improved technology and efficiency through the entire life cycle to prevent energy cannibalism during rapid growth; (ii the elimination of nuclear insecurity to reduce the risks associated with nuclear power so that the free market can indemnify it without substantial public nuclear energy insurance subsidies; (iii the elimination of radioactive waste at the end of life and minimization of environmental impact during mining and operations; and (iv the nuclear industry must regain public trust or face obsolescence as a swarm of renewable energy technologies quickly improve both technical and economic performance.

    Renewable energy development is an arena where ecological, political, and socioeconomic values collide. Advances in renewable energy will incur steep environmental costs to landscapes in which facilities are constructed and operated. Scientists - including those from academia, industry, and government agencies - have only recently begun to quantify trade-off in this arena, often using ground-mounted, utility-scale solar energy facilities (USSE, ≥ 1 megawatt) as a model. Here, we discuss five critical ecological concepts applicable to the development of more sustainable USSE with benefits over fossil-fuel-generated energy: (1) more sustainable USSE development requires careful evaluation of trade-offs between land, energy, and ecology; (2) species responses to habitat modification by USSE vary; (3) cumulative and large-scale ecological impacts are complex and challenging to mitigate; (4) USSE development affects different types of ecosystems and requires customized design and management strategies; and (5) long-term ecological consequences associated with USSE sites must be carefully considered. These critical concepts provide a framework for reducing adverse environmental impacts, informing policy to establish and address conservation priorities, and improving energy production sustainability.

    An increase in the price of imported fossil fuels indirectly increases the producer price in non-energy sectors; however, this indirect influence cannot be taken into account by the traditional portfolio approach. This study proposes an analytical framework combining the input-output (I-O) model and the portfolio approach that can take the indirect influence into account. A risk of an increase in the producer price in Japanese non-energy sectors during the period 1970-2000 is estimated, and the causes of a decrease in the risk through the analysis period are clarified by decomposing an index of the risk. The result indicates that almost all non-energy sectors have decreased this risk during the analysis period. The degree and cause of the decrease depends on a sector's location in the hierarchical structure of Japanese industries. For example, assembly sectors have decreased their risk mainly as the result of improvement in energy usage by upstream sectors, such as material sectors, rather than their own improvements. Proper policies considering such a structure are required to decrease the risk further because the effort taken to do so is seldom motivated by economic profit.

    A regression analysis is performed to make projections for the Canadian energy production and consumption. These have been increasing and are projected to increase even further in the near future. The primary energy production and consumption are projected to increase by 52% and 34%, respectively, by 2025 over 2004 if business as usual. The amount of fossil energy resources is finite and the extraction, transportation and combustion of fossil fuels cause environmental pollution and climate change. On the other hand, energy plays an important role in the economic and social development of Canada. Canada can develop further from an energy balance point of view, but this alone cannot be sustainable, because of the negative consequences of the major energy use on the environment. Application of energy localization and diversification is a promising solution, but in order to reach that, better energy efficiency and more use of renewable energy are necessary. Instead of non-compulsory policies Canada's policy approach should have more compulsory policies. Only then Canada can be made to develop further in a sustainable manner

    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

  15. On the Sustainability and Progress of Energy Neutral Mineral Processing

    Full Text Available A number of primary ores such as phosphate rock, gold-, copper- and rare earth ores contain considerable amounts of accompanying uranium and other critical materials. Energy neutral mineral processing is the extraction of unconventional uranium during primary ore processing to use it, after enrichment and fuel production, to generate greenhouse gas lean energy in a nuclear reactor. Energy neutrality is reached if the energy produced from the extracted uranium is equal to or larger than the energy required for primary ore processing, uranium extraction, -conversion, -enrichment and -fuel production. This work discusses the sustainability of energy neutral mineral processing and provides an overview of the current progress of a multinational research project on that topic conducted under the umbrella of the International Atomic Energy Agency.

    Full Text Available Analyses of possible synergies between energy recovery and water management are essential for achieving sustainable improvements in the performance of irrigation water networks. Improving the energy efficiency of water systems by hydraulic energy recovery is becoming an inevitable trend for energy conservation, emissions reduction, and the increase of profit margins as well as for environmental requirements. This paper presents the state of the art of hydraulic energy generation in drinking and irrigation water networks through an extensive review and by analyzing the types of machinery installed, economic and environmental implications of large and small hydropower systems, and how hydropower can be applied in water distribution networks (drinking and irrigation where energy recovery is not the main objective. Several proposed solutions of energy recovery by using hydraulic machines increase the added value of irrigation water networks, which is an open field that needs to be explored in the near future.

    Turkey's demand for energy and electricity is increasing rapidly and heavily dependent on expensive imported energy resources that place a big burden on the economy and air pollution is becoming a great environmental concern in the country. As would be expected, the rapid expansion of energy production and consumption has brought with it a wide range of environmental issues at the local, regional and global levels. With respect to global environmental issues, Turkey's carbon dioxide (CO 2 ) emissions have grown along with its energy-consumption. States have played a leading role in protecting the environment by reducing emissions of greenhouse gases (GHGs). In this regard, renewable energy resources appear to be the one of the most efficient and effective solutions for clean and sustainable energy development in Turkey. Turkey's geographical location has several advantages for extensive use of most of these renewable energy sources.

    The AFD (the French Agency for Development) and the FFEM (French Fund for World Environment) are involved in cooperation and partnership projects for the development of energy efficiency, notably, but not only, in developing and emerging countries. This report first proposes a classification of these projects according to a typology which comprises the concerned sectors (urban planning and housing, fuels, hydroelectricity and wind energy, electricity distribution, industries and services, transports and mobility, capacity building, multi-sector), the intervener (AFD, FFEM, and Proparco, an AFD's subsidy), the project evolution in time (number of projects, evolution of funding), the funding type (loan types, subsidy, credit line), and the geographical area. The second part discusses the conditions to start projects in energy management: legal framework, economic conditions, funding, social and environmental factors, and technical factors. Appendices propose a set of ten technical sheets which indicate and discuss conditions of success as well as obstacles for different types of projects: big dams, mini hydroelectric projects, wind energy, biomass/biogas co-generation, bio-fuels, decentralised rural electrification based on renewable energy projects, collective transports and energy efficiency in transports, development of partnerships and institutional support, multi-sector tools of investment, and carbon market

    SECTOR is a large-scale European project with a strong consortium of over 20 partners from industry and science. The project is focussed on the further development of torrefaction-based technologies for the production of solid bioenergy carriers up to pilot-plant scale and beyond, and on supporting the market introduction of torrefaction-based bioenergy carriers as a commodity renewable solid fuel. The torrefaction of biomass materials is considered to be a very promising technology for the promotion of the large-scale implementation of bioenergy. During torrefaction biomass is heated up in the absence of oxygen to a temperature of 250-320 C. By combining torrefaction with pelletisation or briquetting, biomass materials can be converted into a high-energy-density commodity solid fuel or bioenergy carrier with improved behaviour in (long-distance) transport, handling and storage, and also with superior properties in many major end-use applications. Torrefaction has the potential to provide a significant contribution to an enlarged raw material portfolio for biomass fuel production inside Europe by including both agricultural and forestry biomass. In this way, the SECTOR project is expected to shorten the time-to-market of torrefaction technology and to promote market introduction within stringent sustainability boundary conditions. The European Union provides funding for this project within the Seventh Framework Programme. The project has a duration of 42 months and started in January 2012. (orig.)

    The production and use of biomass for energy has both positive and negative impacts on the environment. The environmental impacts of energy crops should be clarified before political choices concerning energy are made. An important aid to policy-making would be a systematic methodology to assess the environmental sustainability of energy crops. So far, most studies on the environmental aspects of energy crops deal mainly with the energy production of the crops and the possible consequences for CO 2 mitigation. The Dutch Centre for Agriculture and Environment (CLM) has developed a systematic methodology to assess the ecological and socio-economic sustainability of biomass crops. The method is best described as a multicriteria analysis of process chains and is very much related to Life Cycle Assessment (LCA). Characteristics of our methodology are the use of: definition of functional units; analysis of the entire lifecycle; definition of yield levels and corresponding agricultural practices; analysis of both ecological and economic criteria; definition of reference systems; definition of procedures for normalisation and weighting. CLM has applied the method to assess the sustainability of ten potentially interesting energy crops in four European regions. The results are used to outline the perspectives for large scale production of biomass crops with regard to the medium and long term land availability in Europe. For the crops considered, net energy budget ranges from 85 GJ net avoided energy per ha for rape seed for fuel to 248 GJ net avoided fossil energy per ha for silage maize for electricity from gasification. The methodology of the tool and its results were discussed at the concerted action ''Environmental aspects of biomass production and routes for European energy supply'' (AIR3-94-2455), organised by CLM in 1996. Major conclusions of the research: multicriteria analyhsis of process lifecycles is at present the best available option to assess the ecological
