Many factors have emerged for change towards cleaner and more efficient technologies and services: climate change, increasing oil demands, and rising living standards in many parts of the world are putting an ever-increasing strain on the environment. Recently, these drivers have fueled the formation of a clean energy venture capital market where both independent venture capitalists (VCs) and corporate venture capitalists (CVCs) have invested in clean energy start-ups. Financing of clean energy market creation is the focus of this dissertation. The dissertation contributes to several bodies of literature in the area of entrepreneurship, new industry creation, corporate venturing, and venture capital research. The dissertation uses a grounded theory approach. The study is guided by three data collection approaches with an emphasis on the first two. First, interviews with European and North American VC and CVC firms that have invested in the clean energy sector were carried out. Second, a clean energy venture financing survey that consisted of qualitative, essay-format questions and some quantitative questions was carried out. Third, interviews with clean energy stakeholders were carried out in order to gain a better understanding of the emerging sector. The research results consist of three main findings. First, the research results suggest that clean energy ventures face the following three main entrepreneurial challenges: financing, market education, and growth management. A further study of three clean energy industry categories revealed additional challenges that varied according to the industry development stage. Second, the results demonstrate that, from a venture capitalist perspective, clean energy venture risk characteristics can be divided into two groups: generally recognized risk characteristics and cognitive risk characteristics. The identified generally recognized risk characteristics were market demand and adaptation, incompatibility with the VC model

Pao, Hsiao-Tien; Li, Yi-Ying; Hsin-Chia Fu

2014-01-01

This paper explores the causal relationship between clean (renewable/nuclear) and non-clean energy consumption and economic growth in emerging economies of the MIST (Mexico, Indonesia, South Korea, and Turkey) countries. The panel co-integration tests reveal that there is a long-term equilibrium relationship among GDP, capital formation, labor force, renewable/nuclear, and fossil fuel energy consumption. The panel causality results indicate that (1) there is a positive unidirectional short-run causality from fossil fuel energy consumption to economic growth with a bidirectional long-run causality; (2) there is a unidirectional long-run causality from renewable energy consumption to economic growth with positive bidirectional short-run causality, and a long-run causality from renewable to fossil fuel energy consumption with negative short-run feedback effects; and (3) there is a bidirectional long-run causality between nuclear energy consumption and economic growth and a long-run causality from fossil fuel energy consumption to nuclear energy consumption with positive short-run feedback effects. These suggest that MIST countries should be energy-dependent economies and that energy conservation policies may depress their economic development. However, developing renewable and nuclear energy is a viable solution for addressing energy security and climate change issues, and creating clean and fossil fuel energy partnerships could enhance a sustainable energy economy. - Highlights: • This novel study can provide more robust bases to strengthen sustainable energy policy settings. • Fossil fuel/nuclear energy use and economic growth is bidirectional causality. • Renewable energy consumption long term causes economic growth. • There is substitutability between renewable and fossil fuel energy. • Clean and non-clean energy partnerships can achieve a sustainable energy economy

The Excel based tool incorporates hourly climate based building loads data to arrive at the composite energy demand for the district and compares the Net Present Value (NPV) of the costs of CHP/DE alternatives. This tool has been used to provide assistance to several projects in the Northeast, Mid-Atlantic, Intermountain and Pacific Regions. The tool was disseminated to the CEACs and supplemented by a Training Webinar and a How to Guide IDEA produced a US Community Energy Development Guide to support mayors, planners, community leaders, real estate developers and economic development officials who are interested in planning more sustainable urban energy infrastructure, creating community energy master plans and implementing CHP/ District Energy systems in cities, communities and towns. IDEA has collected industry data and provided a comprehensive data set containing information on District Energy installations in the US. District energy systems are present in 49 states and theDistrict of Columbia. Of the 597 systems 55% were DE alone while the remainder was some combination of CHP, district heating, and district cooling. District energy systems that do not currently involve electric generation are strong near-term candidates for the adoption of CHP due to the magnitude of their aggregated thermal load. This data has helped inform specific and targeted initiatives including technical assistance provided by the CEAC’s for EPA’s Boiler MACT Compliance by large District Heating System boilers. These outcomes have been greatly enabled by the close coordination and collaboration with DOE CEAC leadership and with the eight regional US DOE Clean Energy Application Centers and the award’s incremental funding has allowed IDEA to leverage our resources to be an effective champion for Clean Energy.

Tracking Clean Energy Progress 2013 (TCEP 2013) examines progress in the development and deployment of key clean energy technologies. Each technology and sector is tracked against interim 2020 targets in the IEA Energy Technology Perspectives 2012 2°C scenario, which lays out pathways to a sustainable energy system in 2050. Stark message emerge: progress has not been fast enough; large market failures are preventing clean energy solutions from being taken up; considerable energy efficiency remains untapped; policies need to better address the energy system as a whole; and energy-related research, development and demonstration need to accelerate. Alongside these grim conclusions there is positive news. In 2012, hybrid-electric vehicle sales passed the 1 million mark. Solar photovoltaic systems were being installed at a record pace. The costs of most clean energy technologies fell more rapidly than anticipated.

This is a NEDO (New Energy and Industrial Technology Development Organization) report on alternate energy dated July 15, 1989 (based on a Koleda Childress and Company of EPA analysis). Development of fossil and synthetic fuels in the United States is stated. President Bush on July 12 proposed amendments to the Clean Air Act of 1970. The amendments involve acid rain, urban air pollution, and toxic air pollutants. The proposal will greatly influence the development of new energies, especially in relation to clean coal technology and increase in the use of methanol as alternate automobile fuel. The power and coal industries will be requested, with attention paid to the SOx and NOx emissions reduction schedule, to operate scrubbers, burn low-sulfur coal, convert to natural gas, and to close old facilities. Long-term clean fuel programs will be amalgamated with the proposal of President Bush, and production of methanol-driven automobiles and their fuel will be given a boost. Such will be effected in nine heavily-polluted cities for an increase from 500,000 automobiles in 1995 to 8,250,000 in 2004. Reference is also made to the budget. (NEDO)

Clean energy and the hydrogen economy.

In recent years, new-found interest in the hydrogen economy from both industry and academia has helped to shed light on its potential. Hydrogen can enable an energy revolution by providing much needed flexibility in renewable energy systems. As a clean energy carrier, hydrogen offers a range of benefits for simultaneously decarbonizing the transport, residential, commercial and industrial sectors. Hydrogen is shown here to have synergies with other low-carbon alternatives, and can enable a more cost-effective transition to de-carbonized and cleaner energy systems. This paper presents the opportunities for the use of hydrogen in key sectors of the economy and identifies the benefits and challenges within the hydrogen supply chain for power-to-gas, power-to-power and gas-to-gas supply pathways. While industry players have already started the market introduction of hydrogen fuel cell systems, including fuel cell electric vehicles and micro-combined heat and power devices, the use of hydrogen at grid scale requires the challenges of clean hydrogen production, bulk storage and distribution to be resolved. Ultimately, greater government support, in partnership with industry and academia, is still needed to realize hydrogen's potential across all economic sectors.This article is part of the themed issue 'The challenges of hydrogen and metals'. © 2017 The Author(s).

The Clean Energy Infrastructure Educational Initiative represents a collaborative effort by the University of Dayton, Wright State University and Sinclair Community College. This effort above all aimed to establish energy related programs at each of the universities while also providing outreach to the local, state-wide, and national communities. At the University of Dayton, the grant has aimed at: solidfying a newly created Master's program in Renewable and Clean Energy; helping to establish and staff a regional sustainability organization for SW Ohio. As well, as the prime grantee, the University of Dayton was responsible for insuring curricular sharing between WSU and the University of Dayton. Finally, the grant, through its support of graduate students, and through cooperation with the largest utilities in SW Ohio enabled a region-wide evaluation of over 10,000 commercial building buildings in order to identify the priority buildings in the region for energy reduction. In each, the grant has achieved success. The main focus of Wright State was to continue the development of graduate education in renewable and clean energy. Wright State has done this in a number of ways. First and foremost this was done by continuing the development of the new Renewable and Clean Energy Master's Degree program at Wright State . Development tasks included: continuing development of courses for the Renewable and Clean Energy Master's Degree, increasing the student enrollment, and increasing renewable and clean energy research work. The grant has enabled development and/or improvement of 7 courses. Collectively, the University of Dayton and WSU offer perhaps the most comprehensive list of courses in the renewable and clean energy area in the country. Because of this development, enrollment at WSU has increased from 4 students to 23. Secondly, the grant has helped to support student research aimed in the renewable and clean energy program. The grant helped to solidify

Clean Cities is a government-industry partnership sponsored by the U.S. Department of Energy's (DOE) Vehicle Technologies Program, which is part of the Office of Energy Efficiency and Renewable Energy. Working with its network of about 100 local coalitions and more than 6,500 stakeholders across the country, Clean Cities delivers on its mission to reduce petroleum consumption in on-road transportation. In its work to reduce petroleum use, Clean Cities focuses on a portfolio of technologies that includes electric drive, propane, natural gas, renewable natural gas/biomethane, ethanol/E85, biodiesel/B20 and higher-level blends, fuel economy, and idle reduction. Over the past 17 years, Clean Cities coalitions have displaced more than 2.4 billion gallons of petroleum; they are on track to displace 2.5 billion gallons of gasoline per year by 2020. This Clean Cities Strategic Plan lays out an aggressive five-year agenda to help DOE Clean Cities and its network of coalitions and stakeholders accelerate the deployment of alternative fuel and advanced technology vehicles, while also expanding the supporting infrastructure to reduce petroleum use. Today, Clean Cities has a far larger opportunity to make an impact than at any time in its history because of its unprecedented $300 million allocation for community-based deployment projects from the American Recovery and Reinvestment Act (ARRA) (see box below). Moreover, the Clean Cities annual budget has risen to $25 million for FY2010 and $35 million has been requested for FY2011. Designed as a living document, this strategic plan is grounded in the understanding that priorities will change annually as evolving technical, political, economic, business, and social considerations are woven into project decisions and funding allocations. The plan does not intend to lock Clean Cities into pathways that cannot change. Instead, with technology deployment at its core, the plan serves as a guide for decision-making at both the

The technical development of clean energy including the utilization of solar energy was begun in 1973 at the time of the oil crisis, and about 20 years elapsed. Also in Japan, the electric power buying system by electric power companies for solar light electric power and wind electric power has been started in 1992, namely their value as a merchandise was recognized. As for these two technologies, the works of making the international standards and JIS were begun. The range of clean energy or natural energy is wide, and its kinds are many. The utilization of solar heat and the electric power generation utilizing waves, tide and geotherm already reached the stage of practical use. Generally in order to practically use new energy, the problem of price must be solved, but the price is largely dependent on the degree of spread. Also the reliability, durability and safety must be ensured, and the easiness of use, effectiveness and trouble-saving maintenance and operation are required. For the purpose, it is important to packaging those skillfully in a system. The cases of intelligent natural energy systems are shown. Solar light and wind electric power generation systems and the technology of transporting clean energy are described. (K.I.)

2010-05-15

With the depletion of conventional resources and the increasing concerns about the environment, emphasis has been put on developing clean energy. Clean energy is expected to become one of the main industrial sectors within the next decade, thus creating numerous jobs. While significant investments have been made by several countries to shift to clean energy, Canada is investing in highly polluting resources such as the tar sands. It is shown that if Canada were to match U.S. efforts in terms of clean energy on a per person basis, they would need to invest 11 billion additional dollars and this would result in the creation of 66,000 clean energy jobs. This paper showed that Canada is falling behind in terms of clean energy and the authors recommend that the Canadian government match U.S. investments and design policies in support of clean energy and put a price on carbon so as to favor the development of the clean energy sector and its consequent job creation.

With problems inherent to clean energy vehicles such as cruising distance, fuel supply and fuel consumption, ACEVs (advanced clean energy vehicles) are in demand featuring both low pollution and high efficiency compatibly. This paper explains the fiscal 2000 results of development. The target is, by using oil-alternative fuel, to reduce driving energy consumption and carbon dioxide emission to less than half and to control the life cycle cost (total of manufacturing cost, operating cost, fuel cost, etc.) to not more than twice as much as those of conventional vehicles. As ACEVs, an ANG (adsorbed natural gas) engine and flywheel battery mounted passenger car was selected, as were a CNG ceramics engine and capacitor mounted truck, CNG engine and lithium-ion battery mounted truck, LNG engine and capacitor mounted bus, and a DME engine and capacitor mounted bus. All are hybrid systems with an energy saving device. In the research of synthetic fuels, the results of the studies were summarized including the effect of various synthetic light oils on engine performance, fuel characteristics, effect of PM grain size and the optimum properties.

G-20 Clean Energy, and Energy Efficiency Deployment and Policy Progress, a report prepared by the International Energy Agency (IEA) in collaboration with the G-20 Clean Energy and Energy Efficiency Working Group, provides an overview of clean energy and energy efficiency technology deployment and summarises support policies in place across G-20 countries. The report highlights that while clean energy technology deployment has made steady progress and energy efficiency improvements have been made, continued reliance on fossil fuels to meet growth in global energy demand presents a significant challenge. Scaling-up the deployment of renewable energy, in addition to improving end-use efficiency, enhancing the efficiency of fossil fuel based power generation, and supporting the widespread deployment of CCS will, therefore, also be crucial aspects of the transition to a cleaner energy future. Because the G-20 group of countries represent close to 80% of energy-related CO2 emissions, by developing and deploying energy efficiency and clean energy technologies, they are presented with a unique opportunity to make collective progress in transitioning the global energy system. IEA Deputy Executive Director Richard Jones emphasised the importance of G-20 efforts, saying, 'The IEA welcomes this important collaboration with the G-20. Enhanced deployment of clean energy technologies and of energy efficiency improvements offers energy security and environmental benefits. It will also enable cost savings over the medium and long term -- an aspect that is particularly relevant at a time of economic uncertainty. We believe that enhanced policy assessment and analysis, building on this initial report, will enable governments to take more cost effective and efficient policy decisions.'

Promoting clean energy technology entrepreneurship: The role of external context

International Nuclear Information System (INIS)

Malen, Joel; Marcus, Alfred A.

2017-01-01

This study examines how political, social and economic factors influence clean energy technology entrepreneurship (CETE). Government policies supporting clean energy technology development and the development of markets for clean energy create opportunities for CETE. However, the extent to which such opportunities lead to the emergence of new clean energy businesses depends on a favorable external context promoting CETE. This study employs a novel dataset combining indicators of the policy and social context of CETE with information on clean energy technology startup firms in the USA to provide empirical evidence that technological and market conditions supporting clean energy induce more extensive CETE under contexts where local attention to clean energy issues and successful firms commercializing clean energy technologies are more prominent. By establishing that CETE is contingent upon a supportive local environment as well as technology and market opportunities, the study holds relevance for policy makers and clean energy technology firms. - Highlights: • Influence of political, social and economic factors on clean energy technology entrepreneurship (CETE). • CETE more prominent with clean energy technology availability. • Greater when local attention interacts with technology availability and market opportunities. • Greater when local firms successfully commercialize technologies. • Novel dataset and Arellano-Bond dynamic panel estimation.

Alternative energy as a factor of ecological and energy security: features of Russia

Directory of Open Access Journals (Sweden)

Boris Nikolaevich Porfiryev

2011-06-01

Full Text Available This paper analyzes the current situation in the sphere of alternative energy engineering in Russia. On the one hand, the national economy and the population in general do not have problems with energy supply and Russia in general is the world's largest exporter of energy. On the other hand, centralized energy supply covers only one third of its territory and two-thirds are in the area of decentralized and autonomous power supply. In the current situation, energy sources that are independent of centralized networks based on clean technologies are a promising alternative. The paper assesses the current state of alternative energy development in the world and in Russia, its potential and prospects. It was found out that development and qualitative improvement of the regulatory framework should have priority for alternative energy mastering in Russia as well as active joint action of government, business and civic leaders to gradually consolidate in public consciousness and behaviour of a new culture of energy consumption based on the rules of economy and environmental safety. The analysis of the proposals for the development of alternative energy industries in Russia was made. Particular attention is paid to energy saving experience and energy efficiency in housing services and public utilities. Questions on the creation and development of formal and informal institutions of non-conventional energy sources usage are asked.

Data cleaning in the energy domain

Science.gov (United States)

Akouemo Kengmo Kenfack, Hermine N.

This dissertation addresses the problem of data cleaning in the energy domain, especially for natural gas and electric time series. The detection and imputation of anomalies improves the performance of forecasting models necessary to lower purchasing and storage costs for utilities and plan for peak energy loads or distribution shortages. There are various types of anomalies, each induced by diverse causes and sources depending on the field of study. The definition of false positives also depends on the context. The analysis is focused on energy data because of the availability of data and information to make a theoretical and practical contribution to the field. A probabilistic approach based on hypothesis testing is developed to decide if a data point is anomalous based on the level of significance. Furthermore, the probabilistic approach is combined with statistical regression models to handle time series data. Domain knowledge of energy data and the survey of causes and sources of anomalies in energy are incorporated into the data cleaning algorithm to improve the accuracy of the results. The data cleaning method is evaluated on simulated data sets in which anomalies were artificially inserted and on natural gas and electric data sets. In the simulation study, the performance of the method is evaluated for both detection and imputation on all identified causes of anomalies in energy data. The testing on utilities' data evaluates the percentage of improvement brought to forecasting accuracy by data cleaning. A cross-validation study of the results is also performed to demonstrate the performance of the data cleaning algorithm on smaller data sets and to calculate an interval of confidence for the results. The data cleaning algorithm is able to successfully identify energy time series anomalies. The replacement of those anomalies provides improvement to forecasting models accuracy. The process is automatic, which is important because many data cleaning processes

Using energy scenarios to explore alternative energy pathways in California

International Nuclear Information System (INIS)

Ghanadan, Rebecca; Koomey, J.G.

2005-01-01

This paper develops and analyzes four energy scenarios for California that are both exploratory and quantitative. The business-as-usual scenario represents a pathway guided by outcomes and expectations emerging from California's energy crisis. Three alternative scenarios represent contexts where clean energy plays a greater role in California's energy system: Split Public is driven by local and individual activities; Golden State gives importance to integrated state planning; Patriotic Energy represents a national drive to increase energy independence. Future energy consumption, composition of electricity generation, energy diversity, and greenhouse gas emissions are analyzed for each scenario through 2035. Energy savings, renewable energy, and transportation activities are identified as promising opportunities for achieving alternative energy pathways in California. A combined approach that brings together individual and community activities with state and national policies leads to the largest energy savings, increases in energy diversity, and reductions in greenhouse gas emissions. Critical challenges in California's energy pathway over the next decades identified by the scenario analysis include dominance of the transportation sector, dependence on fossil fuels, emissions of greenhouse gases, accounting for electricity imports, and diversity of the electricity sector. The paper concludes with a set of policy lessons revealed from the California energy scenarios

Municipal governments in the United States are well positioned to influence clean energy (energy efficiency and alternative energy) and transportation technology and strategy implementation within their jurisdictions through planning, programs, and codification. Municipal governments are leveraging planning processes and programs to shape their energy futures. There is limited understanding in the literature related to codification, the primary way that municipal governments enact enforceable policies. The authors fill the gap in the literature by documenting the status of municipal codification of clean energy and transportation across the United States. More directly, we leverage online databases of municipal codes to develop national and state-specific representative samples of municipal governments by population size. Our analysis finds that municipal governments with the authority to set residential building energy codes within their jurisdictions frequently do so. In some cases, communities set codes higher than their respective state governments. Examination of codes across the nation indicates that municipal governments are employing their code as a policy mechanism to address clean energy and transportation.

The governance of clean energy in India: The clean development mechanism (CDM) and domestic energy politics

International Nuclear Information System (INIS)

Phillips, Jon; Newell, Peter

2013-01-01

This paper explores the ways in which clean energy is being governed in India. It does so in order to improve our understanding of the potential and limitations of carbon finance in supporting lower carbon energy transitions, and to strengthen our appreciation of the role of politics in enabling or frustrating such endeavors. In particular we emphasize the importance of politics and the nature of India's political economy in understanding the development of energy sources and technologies defined as ‘clean’ both by the United Nations Clean Development Mechanism (CDM) and leading international actors. By considering the broad range of institutions that exert formal and informal political influence over how the benefits and costs of the CDM are distributed, the paper highlights shortcomings in the narrow way in which CDM governance has been conceptualized to date. This approach goes beyond analysis of technocratic aspects of governance – often reduced to a set of institutional design issues – in order to appreciate the political nature of the trade-offs that characterize debates about India's energy future and the relations of power which will determine how, and on whose terms, they are resolved. - Highlights: • Clean energy governance in practice is shaped by political power and influence. • Governance of clean energy requires strong institutions from local to global levels. • Un-governed areas of energy policy are often as revealing of the exercise of power as areas where there explicit policy is in place. • Climate and carbon finance interventions need to better understand the landscape of political power which characterises India’s energy sector

Policies, programs, and current status of alternate energy and global warming concerns in the United States are reported. The Department of Energy has announced the selection of nine projects out of 33 in the fourth phase of its Clean Coal Technology Program. The nine projects include TAMCO Power Partner's 107MW integrated gasification combined cycle demonstration project, Union Carbide Chemicals and Plastics Company, Inc.'s regenerable flue gas desulfurization system, and Custom Coals International's self-scrubbing coal technology. The American Petroleum Institute has announced that government mandated use of alternative transportation fuels would be uneconomical and do little to improve U.S. energy security and environmental quality. The Environmental Protection Agency's Clean Fuels Advisory Committee has forged an agreement between the agency, environmental organizations, and the petroleum industry covering the production and sale of reformulated gasoline. Despite growing international pressure relative to greenhouse gas emission reduction targets and timetables, the Bush Administration is expected to maintain its resistance at an international climate treaty negotiation session to take place in Nairobi, Kenya.

Clean energy: Revisiting the challenges of industrial policy

International Nuclear Information System (INIS)

Morris, Adele C.; Nivola, Pietro S.; Schultze, Charles L.

2012-01-01

Large public investments in clean energy technology arguably constitute an industrial policy. One rationale points to market failures that have not been corrected by other policies, most notably greenhouse gas emissions and dependence on oil. Another inspiration for clean energy policy reflects economic arguments of the 1980s. It suggests strategic government investments would increase U.S. firms' market share of a growing industry and thus help American firms and workers. This paper examines the reasoning for clean energy policy and concludes that: •While a case can be made that subsidizing clean energy might help address market failures, the case may be narrower than some assert, and turning theory into sound practice is no simple feat. •An appropriate price on greenhouse gases is an essential precondition to ensuring efficient incentives to develop and deploy cost-effective emissions-abating technologies. However, efficient prices alone are unlikely to generate efficient levels of basic research and development by private firms. •Government investments in clean energy are unlikely to produce net increases in employment in the long run, in part because pushing home-grown technologies at taxpayers' expense offers no guarantee that the eventual products ultimately would not be manufactured somewhere else. •Spending on clean energy technologies is not well suited to fiscal stimulus. The authors recommend that: •Federal energy spending should invest in technologies with the lowest expected cost of abatement and highest probability of market penetration. •Funding decisions ought to be insulated – as much as possible – from rent-seeking by interest groups, purely political distortions, and the parochial preferences of legislators. - Highlights: ► Clean energy technology policy may be less justifiable than many assert, and doing it well is hard. ► The government should appropriately price greenhouse gas emissions and fund technology R and D. �

Technology development in the clean energy and broader clean tech space has proven to be challenging. Long-standing methods for advancing clean energy technologies from science to commercialization are best known for relatively slow, linear progression through research and development, demonstration, and deployment (RDD&D); and characterized by well-known valleys of death for financing. Investment returns expected by traditional venture capital investors have been difficult to achieve, particularly for hardware-centric innovations, and companies that are subject to project finance risks. Commercialization support from incubators and accelerators has helped address these challenges by offering more support services to start-ups; however, more effort is needed to fulfill the desired clean energy future. The emergence of new strategic investors and partners in recent years has opened up innovative opportunities for clean tech entrepreneurs, and novel commercialization models are emerging that involve new alliances among clean energy companies, RDD&D, support systems, and strategic customers. For instance, Wells Fargo and Company (WFC) and the National Renewable Energy Laboratory (NREL) have launched a new technology incubator that supports faster commercialization through a focus on technology development. The incubator combines strategic financing, technology and technical assistance, strategic customer site validation, and ongoing financial support.

New methods are needed to accelerate clean energy policy adoption. To that end, this study proposes an innovative financing scheme for renewable and energy efficiency deployment. Financing barriers represent a notable obstacle for energy improvements and this is particularly the case for low income households. Implementing a policy such as PACE—property assessed clean energy—allows for the provision of upfront funds for residential property owners to install electric and thermal solar systems and make energy efficiency improvements to their buildings. This paper will inform the design of better policies tailored to the creation of the appropriate conditions for such investments to occur, especially in those countries where most of the population belongs to the low–middle income range facing financial constraints.

The U.S. Department of Energy's (DOE) Clean Cities program advances the nation's economic, environmental, and energy security by supporting local actions to cut petroleum use in transportation. A national network of nearly 100 Clean Cities coalitions brings together stakeholders in the public and private sectors to deploy alternative and renewable fuels, idle-reduction measures, fuel economy improvements, and new transportation technologies, as they emerge. Each year DOE asks Clean Cities coordinators to submit annual reports of their activities and accomplishments for the previous calendar year. Data and information are submitted via an online database that is maintained as part of the Alternative Fuels Data Center (AFDC) at the National Renewable Energy Laboratory (NREL). Coordinators submit a range of data that characterizes the membership, funding, projects, and activities of their coalitions. They also submit data about sales of alternative fuels, deployment of alternative fuel vehicles (AFVs) and hybrid electric vehicles (HEVs), idle-reduction initiatives, fuel economy activities, and programs to reduce vehicle miles traveled (VMT). NREL analyzes the data and translates them into petroleum-use reduction impacts, which are summarized in this report.

In 2003, the National Association of Regulatory Utility Commissioners (NARUC) and National Energy Technology Laboratories (NETL) collaboratively established the International Clean Energy Coalition (ICEC). The coalition consisting of energy policy-makers, technologists, and financial institutions was designed to assist developing countries in forming and supporting local approaches to greenhouse gas mitigation within the energy sector. ICEC's work focused on capacity building and clean energy deployment in countries that rely heavily on fossil-based electric generation. Under ICEC, the coalition formed a steering committee consisting of NARUC members and held a series of meetings to develop and manage the workplan and define successful outcomes for the projects. ICEC identified India as a target country for their work and completed a country assessment that helped ICEC build a framework for discussion with Indian energy decisionmakers including two follow-on in-country workshops. As of the conclusion of the project in 2010, ICEC had also conducted outreach activities conducted during United Nations Framework Convention on Climate Change (UNFCCC) Ninth Conference of Parties (COP 9) and COP 10. The broad goal of this project was to develop a coalition of decision-makers, technologists, and financial institutions to assist developing countries in implementing affordable, effective and resource appropriate technology and policy strategies to mitigate greenhouse gas emissions. Project goals were met through international forums, a country assessment, and in-country workshops. This project focused on countries that rely heavily on fossil-based electric generation.

In the last few years, rare earth materials (REM) prices have experienced a strong increase due to geopolitical and sustainability issues. Financial markets could already have factored in concerns about shortages of REM supplies into clean energy companies’ valuations. We use a multifactor market model for the period January 2006 to September 2012 to analyze the impact of REM price trends – specifically dysprosium and neodymium – on six clean energy indices (NYSE–BNEF) tracking the world's most important companies in the clean energy sector. The results show that during period of price increase, there is a negative relationships between REM price changes and the stock market performance of some clean energy indices. The European clean energy index is also negatively affected, and this effect could be relevant to policy makers, considering that Europe is implementing some relevant policy actions to support the development of the clean energy industry. - Highlights: • Clean energy is an industry with a double-digit growth market rate in the last years. • Rare earth materials are a key component in the development process of this industry. • Recently REMs’ prices have skyrocketed and the clean energy industry is in turmoil. • We analyze the effect of REMs price on the stock market performances of clean industry. • We find negative relation between REMs price increase and stock market performances

Solubility testing with simulated High Level Waste tank heel solids has been conducted in order to evaluate two alternative chemical cleaning technologies for the dissolution of sludge residuals remaining in the tanks after the exhaustion of mechanical cleaning and sludge washing efforts. Tests were conducted with non-radioactive pure phase metal reagents, binary mixtures of reagents, and a Savannah River Site PUREX heel simulant to determine the effectiveness of an optimized, dilute oxalic/nitric acid cleaning reagent and pure, dilute nitric acid toward dissolving the bulk non-radioactive waste components. A focus of this testing was on minimization of oxalic acid additions during tank cleaning. For comparison purposes, separate samples were also contacted with pure, concentrated oxalic acid which is the current baseline chemical cleaning reagent. In a separate study, solubility tests were conducted with radioactive tank heel simulants using acidic and caustic permanganate-based methods focused on the “targeted” dissolution of actinide species known to be drivers for Savannah River Site tank closure Performance Assessments. Permanganate-based cleaning methods were evaluated prior to and after oxalic acid contact.

China is undergoing rapid economic development that generates significant increase in energy demand, primarily for electricity. Energy supply in China is heavily relying on coal, which leads to high carbon emissions. This dissertation explores opportunities for meeting China's growing power demand through clean energy sources. The utilization of China's clean energy sources as well as demand-side management is still at the initial phase. Therefore, development of clean energy sources would require substantial government support in order to be competitive in the market. One of the widely used means to consider clean energy in power sector supplying is Integrated Resource Strategic Planning, which aims to minimize the long term electricity costs while screening various power supply options for the power supply and demand analysis. The IRSP tool tackles the energy problem from the perspective of power sector regulators, and provides different policy scenarios to quantify the impacts of combined incentives. Through three scenario studies, Business as Usual, High Renewable, and Renewable and Demand Side Management, this dissertation identifies the optimized scenario for China to achieve the clean energy target of 2030. The scenarios are assessed through energy, economics, environment, and equity dimensions.

State Clean Energy Policies Analysis: State, Utility, and Municipal Loan Programs

Energy Technology Data Exchange (ETDEWEB)

Lantz, E.

2010-05-01

High initial costs can impede the deployment of clean energy technologies. Financing can reduce these costs. And, state, municipal, and utility-sponsored loan programs have emerged to fill the gap between clean energy technology financing needs and private sector lending. In general, public loan programs are more favorable to clean energy technologies than are those offered by traditional lending institutions; however, public loan programs address only the high up-front costs of clean energy systems, and the technology installed under these loan programs rarely supports clean energy production at levels that have a notable impact on the broader energy sector. This report discusses ways to increase the impact of these loan programs and suggests related policy design considerations.

Mesoporous materials for clean energy technologies.

Alternative energy technologies are greatly hindered by significant limitations in materials science. From low activity to poor stability, and from mineral scarcity to high cost, the current materials are not able to cope with the significant challenges of clean energy technologies. However, recent advances in the preparation of nanomaterials, porous solids, and nanostructured solids are providing hope in the race for a better, cleaner energy production. The present contribution critically reviews the development and role of mesoporosity in a wide range of technologies, as this provides for critical improvements in accessibility, the dispersion of the active phase and a higher surface area. Relevant examples of the development of mesoporosity by a wide range of techniques are provided, including the preparation of hierarchical structures with pore systems in different scale ranges. Mesoporosity plays a significant role in catalysis, especially in the most challenging processes where bulky molecules, like those obtained from biomass or highly unreactive species, such as CO2 should be transformed into most valuable products. Furthermore, mesoporous materials also play a significant role as electrodes in fuel and solar cells and in thermoelectric devices, technologies which are benefiting from improved accessibility and a better dispersion of materials with controlled porosity.

Transition through co-optation: Harnessing carbon democracy for clean energy

Science.gov (United States)

Meng, Kathryn-Louise

This dissertation explores barriers to a clean energy transition in the United States. Clean energy is demonstrably viable, yet the pace of clean energy adoption in the U.S. is slow, particularly given the immediate threat of global climate change. The purpose of this dissertation is to examine the factors inhibiting a domestic energy transition and to propose pragmatic approaches to catalyzing a transition. The first article examines the current political-economic and socio-technical energy landscape in the U.S. Fossil fuels are central to the functioning of the American economy. Given this centrality, constellations of power have been constructed around the reliable and affordable access of fossil fuels. The fossil fuel energy regime is comprised of: political-economic networks with vested interests in continued fossil fuel reliance, and fixed infrastructure that is minimally compatible with distributed generation. A transition to clean energy threatens the profitability of fossil fuel regime actors. Harnessing structural critiques from political ecology and process and function-oriented socio-technical systems frameworks, I present a multi-level approach to identifying pragmatic means to catalyzing an energy transition. High-level solutions confront the existing structure, mid-level solutions harness synergy with the existing structure, and low-level solutions lie outside of the energy system or foster the TIS. This is exemplified using a case study of solar development in Massachusetts. Article two presents a case study of the clean energy technological innovation system (TIS) in Massachusetts. I examine the actors and institutions that support cleantech development. Further, I scrutinize the actors and institutions that help sustain the TIS support system. The concept of a catalyst is presented; a catalyst is an actor that serves to propel TIS functions. Catalysts are critical to facilitating anchoring. Strategic corporate partners are identified as powerful

Innovation, renewable energy, and state investment: Case studies of leading clean energy funds

Over the last several years, many U.S. states have established clean energy funds to help support the growth of renewable energy markets. Most often funded by system-benefits charges (SBC), the 15 states that have established such funds are slated to collect nearly $3.5 billion from 1998 to 2012 for renewable energy investments. These clean energy funds are expected to have a sizable impact on the energy future of the states in which the funds are being collected and used. For many of the organizations tapped to administer these funds, however, this is a relatively new role that presents the challenge of using public funds in the most effective and innovative fashion possible. Fortunately, each state is not alone in its efforts; many other U.S. states and a number of countries are undertaking similar efforts. Early lessons are beginning to be learned by clean energy funds about how to effectively target public funds towards creating and building renewable energy markets. A number of innovative programs have already been developed that show significant leadership by U.S. states in supporting renewable energy. It is important that clean energy fund administrators learn from this emerging experience.

Natural gas - bridge to a clean energy future

International Nuclear Information System (INIS)

Doelman, J.

1991-01-01

Per unit of useful energy natural gas gives the lowest environmental pollution of all fossil fuels. This is due to its low carbon content, the absence of sulphur compounds, and the fact that natural gas can, rather easily, be burnt completely in such a way that also the NO x emission is acceptably low. Although natural gas has already a good record as an efficient and clean fuel large improvements are still possible, but this requires more R+D and time. The presently known natural gas world reserves are high enough to go for a substantially higher share of gas in the energy package. E.g. replacing coal by natural gas will give large environmental improvements. Furthermore, direct gas use is very often the most efficient and cleanest option, also when electricity is an alternative. To develop and connect the known large reserves to the market enormous amounts of money are required. The political and economical situation should make these investments possible and attractive. The ideas first expressed by the Dutch prime minister, now incorporated in the Energy Charter, have been developed to that end. Special attention should be given to the development of small gas fields as is e.g. being done in The Netherlands, which has improved the local gas reserves situation impressively. As a first major step to a clean future the potential of natural gas should be explored and put to work worldwide. Its potential as an important diversified source of energy is underestimated. Amongst others by funding more natural gas R+D natural gas should develop a keyrole in the energy scene of the next 3-5 decades.(author) 3 figs., 8 tabs., 3 refs

This is the Final Technical Report for DOE's Energy Efficiency and Conservation Block Grant, Award No. DE-EE0003813, submitted by St. Lucie County, FL (prime recipient) and the Solar and Energy Loan Fund (SELF), the program's third-party administrator. SELF is a 501(c)(3) and a certified Community Development Financial Institution (CDFI). SELF is a community-based lending organization that operates the Clean Energy Loan Program, which focuses on improving the overall quality of life of underserved populations in Florida with an emphasis on home energy improvements and cost-effective renewable energy alternatives. SELF was launched in 2010 through the creation of the non-profit organization and with a $2.9 million Energy Efficiency and Conservation Block (EECBG) grant from the U.S. Department of Energy (DOE). SELF has its main office and headquarters in St. Lucie County, in the region known as the Treasure Coast in East-Central Florida. St. Lucie County received funding to create SELF as an independent non-profit institution, outside the control of local government. This was important for SELF to create its identity as an integral part of the business community and to help in its quest to become a Community Development Financial Institution (CDFI). This goal was accomplished in 2013, allowing SELF to focus on its mission to increase energy savings while serving markets that have struggled to find affordable financial assistance. These homeowners are most impacted by high energy costs. Energy costs are a disproportionate percentage of household expenses for low to moderate income (LMI) households. Electricity costs have been steadily rising in Florida by nearly 5% per year. Housing in LMI neighborhoods often includes older inefficient structures that further exacerbate the problem. Despite the many available clean energy solutions, most LMI property owners do not have the disposable income or equity in their homes necessary to afford the high upfront cost

The depleting Conventional Energy Resources and highly raised prices of fuel oil, coal, firewood and such other fossil fuels, have forced the mankind to think about the utilization of Alternative / Renewable Sources of Energy. Alternative / Renewable Energy is very attractive, reliable and cost competitive energy. Sun is readily available to provide a clean, abundant and virtually infinite energy to meet the significant portion of mankind's energy-needs. The possible use of renewable-energy sources is discussed in this paper, in order to fill the estimated gap between the available energy-sources and energy-needs of our country in the near future. Designing, Fabrication and Installation of different renewable-energy devices by PCSIR are also discussed in this paper. Different renewable-energy devices such as, solar water heaters, solar cookers, solar dehydrators, solar water-desalination plants, solar heating and cooling of buildings, solar operated absorption-type chiller, solar furnace, solar architecture, developed by PCSIR are discussed in some detail so that the role of renewable-energy sources for their direct use (as heat and power) can be determined. Various technical aspects are discussed to reduce the unit cost with improved efficiency. (author)

The corrosion product of archaeological iron objects is supposed to be removed because it causes re-corrosion. So far it is removed by scapel and sand blaster but they depend on the skill and experience of a conservator and the glass-dust of the sand blaster is harmful to humans. Therefore this study applies a laser cleaning system which is used in various industrial cleaning processes, to remove corrosion product from archaeological iron objects. In addition, this work studies the alternation of corrosion product after laser irradiation, which evaluates the reliability of the laser cleaning system. Optical microscopy, SEM-EDS, XRD, Raman have been used to observe and analyse the surface of the objects. The results show the capacity of laser cleaning some corrosion product, but blackening appears with increasing pulses and laser energy, and some corrosion products, goethite and hematite, are partially altered to magnetite. These problems, blackening and alternation of corrosion product, should be solved by further studies which find the optimal laser irradiation condition and use a wetting agent.

The Clean Air Act Amendments of 1990: Opportunities for Promoting Renewable Energy; Final Report: December 11, 2000

This report explores key aspects of the intersection between the nation's clean air and energy goals and proposes alternatives for encouraging renewable energy in the context of the federal Clean Air Act (CAA). As with most environmental statutes enacted in the early 1970s, the 1970 CAA embraced a somewhat rigid ''command-and-control'' approach to achieving its clean air goals. Although effective, this approach has been criticized for discouraging creative and cost-effective solutions to reducing air emissions. In response to this concern, Congress included the first significant market-based program to address an environmental problem-in this case, acid rain caused by sulfur dioxide (SO2) emissions from power plants-in the 1990 CAA Amendments. This program prompted the federal government and various state governments to pursue other market-based programs to address air pollution problems. Ten years have elapsed since the passage of the 1990 CAA Amendments, so the time is ripe to consider expanding opportunities for renewable energy development in the reform of clean air policies. A significant potential for renewables exists in conjunction with international efforts to reduce emissions of greenhouse gases (GHG), including CO2. Unfortunately, Congressional opposition to international GHG reduction agreements makes it difficult to develop GHG emission-reduction programs, including a cap-and-trade alternative, that would enable the renewables industry to harness this potential. The renewable industry can, however, track developments both nationally and internationally to ensure that the programs developed adequately address renewables.

Concerning alternate energy, a report is made on the status of policies and plans, private sector activities, and global warming mitigation measures in the United States. A Clean Coal Technology Efficiency Improvement Act was introduced in the House of Representatives. Ms Linda Stuntz was named acting Assistant Secretary of Fossil Energy, Department of Energy. The Department of Energy has released a status report on the 35 clean coal projects selected for financial assistance. In the private sector, the Atlantic Richfield Company has announced that it has designed a new reformulated gasoline that rivals methanol in its ability to reduce emissions from motor vehicles. The new gasoline reduces hydrocarbon emissions by 28 percent, evaporative emissions by 36 percent, and nitrogen oxide emissions by 26 percent as compared with conventional gasoline. The United Nations-sponsored second negotiating session in Geneva for an international climate treaty was completed in June, but there was no little substantive progress. It is supposed that the British government is ready to step up international pressure on the United States to take decisive steps to cope with global warming. (NEDO)

Global energy demand is increasing rapidly and due to intensive consumption of different forms of fuels, there are increasing concerns over the reduction in readily available conventional energy resources. Because of the deleterious atmospheric effects of fossil fuels and the uncertainties of future energy supplies, there is a surge of interest to find environmentally friendly alternative energy sources. Hydrogen (H2) has attracted worldwide attention as a secondary energy carrier, since it is the lightest carbon-neutral fuel rich in energy per unit mass and easy to store. Several methods and technologies have been developed for H2 production, but none of them are able to replace the traditional combustion fuel used in automobiles so far. Extensively modified and renovated methods and technologies are required to introduce H2 as an alternative efficient, clean, and cost-effective future fuel. Among several emerging renewable energy technologies, photobiological H2 production by oxygenic photosynthetic microbes such as green algae and cyanobacteria or by artificial photosynthesis has attracted significant interest. In this short review, we summarize the recent progress and challenges in H2-based energy production by means of biological and artificial photosynthesis routes.

The U.S. Department of Energy's (DOE's) Clean Cities program advances the nation's economic, environmental, and energy security by supporting local actions to cut petroleum use and greenhouse gas (GHG) emissions in transportation. A national network of nearly 100 Clean Cities coalitions, whose territory covers 80% of the U.S. population, brings together stakeholders in the public and private sectors to deploy alternative and renewable fuels, idle-reduction (IR) measures, fuel economy improvements, and new transportation technologies as they emerge. Each year, DOE asks Clean Cities coordinators to submit annual reports of their activities and accomplishments for the previous calendar year. Progress reports and information are submitted online as a function of the Alternative Fuels Data Center (AFDC) at the National Renewable Energy Laboratory (NREL). Coordinators report a range of information that characterize the membership, funding, projects, and activities of their coalitions. They also document activities in their region related to the development of refueling/charging infrastructure, sales of alternative fuels; deployment of alternative fuel vehicles (AFVs), plug-in electric vehicles (PEVs), hybrid electric vehicles (HEVs), and plug-in hybrid electric vehicles (PHEVs); idle reduction initiatives; fuel economy improvement activities; and programs to reduce vehicle miles traveled (VMT). NREL analyzes the data and translates them into petroleum-use and GHG emission reduction impacts, which are summarized in this report.

The U.S. Department of Energy Pacific Region Clean Energy Application Center (PCEAC) was formed in 2009 by the U.S. Department of Energy (DOE) and the California Energy Commission to provide education, outreach, and technical support to promote clean energy -- combined heat and power (CHP), district energy, and waste energy recovery (WHP) -- development in the Pacific Region. The region includes California, Nevada, Hawaii, and the Pacific territories. The PCEAC was operated as one of nine regional clean energy application centers, originally established in 2003/2004 as Regional Application Centers for combined heat and power (CHP). Under the Energy Independence and Security Act of 2007, these centers received an expanded charter to also promote district energy and waste energy recovery, where economically and environmentally advantageous. The centers are working in a coordinated fashion to provide objective information on clean energy system technical and economic performance, direct technical assistance for clean energy projects and additional outreach activities to end users, policy, utility, and industry stakeholders. A key goal of the CEACs is to assist the U.S. in achieving the DOE goal to ramp up the implementation of CHP to account for 20% of U.S. generating capacity by 2030, which is estimated at a requirement for an additional 241 GW of installed clean technologies. Additional goals include meeting the Obama Administration goal of 40 GW of new CHP by 2020, key statewide goals such as renewable portfolio standards (RPS) in each state, California’s greenhouse gas emission reduction goals under AB32, and Governor Brown’s “Clean Energy Jobs Plan” goal of 6.5 GW of additional CHP over the next twenty years.

The House Energy and Commerce Committee has approved a 12-title comprehensive energy policy bill. The bill includes provisions on energy efficiency, natural gas, octane mislabelling, Strategic Petroleum Reserve, coal policy, alternative fuels, renewable energy, global warming, uranium enrichment, and power policy. The omnibus energy policy bill passed by the Senate last month contains a provision on a program to transfer U.S. clean coal technologies to developing countries. One of the objectives of the program, which will focus on technologies including pressurized fluidized bed and integrated gasification combined cycle, is to reduce the U.S. trade imbalance. As the climate treaty negotiations of the Intergovernmental Negotiating Committee on a Framework Climate Convention have evolved for a long time, several groups of nations have formed loose and informal coalitions to advocate common positions, for example, coalition of countries of western Europe, of the U.S. and Saudi Arabia, and of less developed countries.

For four years, WWF and Roland Berger have tracked developments in the global clean energy technology (cleantech) sector and ranked countries according to their cleantech sales. The 3rd annual 'Clean Economy, Living Planet' report ranks 40 countries based on the 2011 sales value of the clean energy technology products they manufacture. The report shows that the EU has lost its position to China as the leader in the fast growing global cleantech energy manufacturing sector. However, when cleantech sales are weighted as a percentage of GDP, Denmark and Germany occupied the first and third position globally. Last year the sector's global sales value rose by 10% to almost 200 billion euros, close to the scale of consumer electronics manufacturing. It is projected to overtake oil and gas equipment in the next three years.

many arguments in favor of nuclear energy as a reliable source such as the large size of the plants, their long periods of operation and the expertise with which they are run. The risks associated with radiation are among the most extensively studied hazards known to man but several factors make preserving public anxiety about radiation. Nuclear energy has, in normal operation, a low impact on health and the environment. In order to meet the sustainable development goals, it is necessary to maintain its high standards of safety in spite of increasing competition in the electricity sector and reactors ageing in order to achieve a higher level of public acceptance. The complex technologies used by nuclear fuel cycle facilities are controlled and regulated by international and national institutions. A framework of regulatory, institutional and technical measures is already in place ensuring that the use of nuclear energy does not significantly modify natural environment. The governments have an important role in making the public to understand social, ethical and political issues related to nuclear energy into perspective with the issues raised by alternatives. The paper presents statistical data concerning the weight of nuclear power in Romania, highlights the environmental problems with fossil fuels, discussed the risks and radiological particularly the environmental protection at nuclear power plant. Also, address are the issues of the spent fuel and radioactive wastes from nuclear power plants. (authors)

REVIEW OF ALTERNATIVE ENHANCED CHEMICAL CLEANING OPTIONS FOR SRS WASTE TANKS

Energy Technology Data Exchange (ETDEWEB)

Hay, M.; Koopman, D.

2009-08-01

A literature review was conducted to support the Task Technical and Quality Assurance Plan for Alternative Enhanced Chemical Cleaning (AECC) for sludge heel removal funded as part of the EM-21 Engineering and Technology program. The goal was to identify potential technologies or enhancements to the baseline oxalic acid cleaning process for chemically dissolving or mobilizing Savannah River Site (SRS) sludge heels. The issues with the potentially large volume of oxalate solids generated from the baseline process have driven an effort to find an improved or enhanced chemical cleaning technology for the tank heels. This literature review builds on a previous review conducted in 2003. A team was charged with evaluating the information in these reviews and developing recommendations of alternative technologies to pursue. The new information in this report supports the conclusion of the previous review that oxalic acid remains the chemical cleaning agent of choice for dissolving the metal oxides and hydroxides found in sludge heels in carbon steel tanks. The potential negative impact of large volumes of sodium oxalate on downstream processes indicates that the amount of oxalic acid used for chemical cleaning needs to be minimized as much as possible or the oxalic acid must be destroyed prior to pH adjustment in the receipt tank. The most straightforward way of minimizing the volume of oxalic acid needed for chemical cleaning is through more effective mechanical cleaning. Using a mineral acid to adjust the pH of the sludge prior to adding oxalic acid may also help to minimize the volume of oxalic acid used in chemical cleaning. If minimization of oxalic acid proves insufficient in reducing the volume of oxalate salts, several methods were found that could be used for oxalic acid destruction. For some waste tank heels, another acid or even caustic treatment (or pretreatment) might be more appropriate than the baseline oxalic acid cleaning process. Caustic treatment of high

Wang, Yubao; Cai, Junyu

2018-03-01

This paper uses EU ETS carbon future price and Germany/UK clean energy firms stock indices to study the relationship between carbon market and clean energy market. By structural break test, it is found that the ‘non-stationary’ variables judged by classical unit root test do own unit roots and need taking first difference. After analysis of VAR and Granger causality test, no causal relationships are found between the two markets. However, when Hsiao’s version of causality test is employed, carbon market is found to have power in explaining the movement of stock prices of clean energy firms, and stock prices of clean energy firms also affect the carbon market.

The Future of Nuclear Energy As a Primary Source for Clean Hydrogen Energy System in Developing Countries

International Nuclear Information System (INIS)

Ahmed, K.; Shaaban, H.

2007-01-01

The limited availability of fossil fuels compared to the increasing demand and the connected environmental questions have become topics of growing importance and international attention. Many other clean alternative sources of energy are available, but most of them are either relatively undeveloped technologically or are not yet fully utilized. Also, there is a need for a medium which can carry the produced energy to the consumer in a convenient and environmentally acceptable way. In this study, a fission reactor as a primary energy source with hydrogen as an energy carrier is suggested. An assessment of hydrogen production from nuclear energy is presented. A complete nuclear-electro-hydrogen energy system is proposed for a medium size city (population of 500,000). The whole energy requirement is assessed including residential, industrial and transportation energies. A preliminary economical and environmental impact study is performed on the proposed system. The presented work could be used as a nucleus for a feasibility study for applying this system in any newly established city

The U.S. government, along with other governments, private corporations and organizations, invests significantly in research, development, demonstration and deployment (RDD&D) activities in clean energy technologies, in part to achieve the goal of a clean, secure, and reliable energy system. While specific outcomes and breakthroughs resulting from RDD&D investment are unpredictable, it can be instructive to explore the potential impacts of clean energy RDD&D activities in the power sector and to place those impacts in the context of current and anticipated market trends. This analysis builds on and leverages analysis by the U.S. Department of Energy (DOE) titled “Energy CO₂ Emissions Impacts of Clean Energy Technology Innovation and Policy” (DOE 2017). Similar to DOE (2017), we explore how additional improvements in cost and performance of clean energy technologies could impact the future U.S. energy system; however, unlike the economy-wide modeling used in DOE (2017) our analysis is focused solely on the electricity sector and applies a different and more highly spatially-resolved electric sector model. More specifically, we apply a scenario analysis approach to explore how assumed further advancements in clean electricity technologies would impact power sector generation mix, electricity system costs, and power sector carbon dioxide (CO₂) emissions.

Carbon monoxide, a by-product of the Chemical Process Industries, is a deadly poisonous gas; if released into the atmosphere causes irreparable damage to the environment. A bimetallic catalyst system Ru: Mn doped with different concentrations of 'K' (Potassium) and supported on high surface area alumina support was prepared by co impregnation method, dispersed and reduced at 450 deg. C under hydrogen flow using a closed reactor system at atmospheric pressure for the utilization of poisonous CO gas to produce environmental friendly clean energy. Fischer Tropsch catalyst, when subjected to CO/hydrogenation, gives methane and other hydrocarbon products. The main purpose of this research work was two fold: 1. The powder catalyst when dispersed/reduced on a high surface area oxide support spreads on the surface of the system in a different orientations and shapes. The particle size of the prepared catalysts ranges from 5.0-25.0 nm. The whole system forms a complicated mixture of numerous particles and hence becomes very complicated to study. The characterisation of these randomly oriented particles having different sizes and shapes is a difficult job. This required sensitive UHV spectroscopic techniques like SSIMS, XPS, EEls, XRD and TEM. Their operations needs strong skills. Hence the first aim was to utilize these techniques for the characterization of the prepared catalysts and to establish the usefulness of these techniques in studying such complicated systems. 2. Since Ru is a very good Fischer Tropsch catalyst for the production of aliphatic hydrocarbons product. Our other aim was to find out whether if by surface modification through additives or by surface reconstructing through chemical treatment, we could alter the path of this CO/hydrogenation reaction to produce potentially important unsaturated/aromatic hydrocarbon products. This would serve our dual purpose in which we could use poisonous CO for useful purpose. Hence 'K' potassium as surface modifier is

Hawaii Clean Energy Initiative 2008-2018: Celebrating 10 Years of Success

Energy Technology Data Exchange (ETDEWEB)

2018-01-04

Launched in January 2008, the Hawaii Clean Energy Initiative (HCEI) set out transform Hawaii into a world model for energy independence and sustainability. With its leading-edge vision to transition to a Hawaii-powered clean energy economy within a single generation, HCEI established the most aggressive clean energy goals in the nation. Ten years after its launch, HCEI has significantly outdistanced the lofty targets established as Hawaii embarked on its ambitious quest for energy independence. The state now generates 27 percent of its electricity sales from clean energy sources like wind and solar, placing it 12 percentage points ahead of HCEI's original 2015 RPS target of 15 percent. This brochure highlights some of HCEI's key accomplishments and impacts during its first decade and reveals how its new RPS goal of 100 percent by 2045, which the Hawaii state legislature adopted in May 2015, has positioned Hawaii to become the first U.S. state to produce all of its electricity from indigenous renewable sources.

The Coventry (Lanchester) Polytechnic Wave Energy Group has been involved in the United Kingdom wave energy research programme since its inception in 1975. Whilst the work of the group is mainly concerned with wave energy, and currently is directed towards the design of a wave energy device tailored to the needs of isolated/island communities, it has some involvement with other aspects of the alternatives. This conference, dealing with alternative energy systems and their electrical integration and utilisation was engendered by the general interest which the Polytechnic group members have in the alternatives and their use. The scope for electrical integration and utilisation is very broad. Energy for family groups may be provided in a relatively unsophisticated way which is acceptable to them. Small population centres, for example island communities relying upon diesel equipment, can reap the benefits of the alternatives through their ability to accept novel integration schemes and a flexible approach to the use of the energy available. Consumers already enjoying the benefits of a 'firm' electricity grid supply can use energy from a variety of alternative systems, via the grid, without having to modify their energy consumption habits. In addition to the domestic and industrial applications and coastal possibilities, specialist applications in isolated environments have also emerged. The Proceedings detail practical, technical and economic aspects of the alternatives and their electrical integration and utilisation.

The Clean Energy Transfer : preliminary assesment of the potential for a clean energy transfer between Manitoba and Ontario

International Nuclear Information System (INIS)

2004-09-01

Ontario may have an electrical power shortfall of as much as 25,000 MW by 2020, due to phase-out of coal fired plants, a general increase in demand and existing plants reaching the end of their design lives. Manitoba has approximately 5,000 MW of new hydroelectric power potential which could help to reduce this shortfall. This document reports on a study between the Manitoba government, the Ontario government, Manitoba Hydro, Hydro One, and the Ontario Independent Electricity Market Operator to provide an incremental transfer capability of 1,500 MW between the provinces. This is known as the Clean Energy Transfer Initiative (CETI). The current east-west transmission grid is limited to about 200 MW and is thus not sufficient for this project. Three transmission options have been studied. The report claims that CETI would be the largest single project in terms of greenhouse gas reductions. It is also claimed to potentially benefit Aboriginal groups by increasing employment and business opportunities. Also, tax revenues would be substantial. The most likely alternative energy supply is considered to be the combined cycle gas turbine which, according to the study, would cost about the same amount per MWh, excluding environmental credits. 4 tabs., 11 figs

Development of a comprehensive and effective global clean technology cooperation framework will require years of experimenting and evaluation with new instruments and institutional arrangements before it is clear what works on which scale and in which region or country. In presenting concrete examples, this paper aims to set the first step in that process by highlighting successful models and innovative approaches that can inform efforts to ramp up clean energy technology cooperation. This paper reviews current mechanisms and international frameworks for global cooperation on clean energy technologies, both within and outside of the UNFCCC, and provides selected concrete options for scaling up global cooperation on clean energy technology RD&D, enabling environment, and financing.

New Air Cleaning Strategies for Reduced Commercial Building Ventilation Energy

Energy Technology Data Exchange (ETDEWEB)

Sidheswaran, Meera; Destaillats, Hugo; Sullivan, Douglas P.; Fisk, William J.

2010-10-27

Approximately ten percent of the energy consumed in U.S. commercial buildings is used by HVAC systems to condition outdoor ventilation air. Reducing ventilation rates would be a simple and broadly-applicable energy retrofit option, if practical counter measures were available that maintained acceptable concentrations of indoor-generated air pollutants. The two general categories of countermeasures are: 1) indoor pollutant source control, and 2) air cleaning. Although pollutant source control should be used to the degree possible, source control is complicated by the large number and changing nature of indoor pollutant sources. Particle air cleaning is already routinely applied in commercial buildings. Previous calculations indicate that particle filtration consumes only 10percent to 25percent of the energy that would otherwise be required to achieve an equivalent amount of particle removal with ventilation. If cost-effective air cleaning technologies for volatile organic compounds (VOCs) were also available, outdoor air ventilation rates could be reduced substantially and broadly in the commercial building stock to save energy. The research carried out in this project focuses on developing novel VOC air cleaning technologies needed to enable energy-saving reductions in ventilation rates. The minimum required VOC removal efficiency to counteract a 50percent reduction in ventilation rate for air cleaning systems installed in the HVAC supply airstream is modest (generally 20percent or less).

2010-01-01

The first energy priority of the plan is to provide all Ontarians with a clean, modern and reliable electricity system. It gives a summary of the means implemented to help families and businesses with increasing electricity costs. The plan is to shift the province from a coal-dependent system. Over the next 20 years, 15,000 MW (megawatt) of generating capacity will have to be rebuilt or constructed to replace older Ontario's energy infrastructures. In Ontario, an increase of about 3.5% per year in residential prices, resulting from the need to enjoy clean air, reliable generation and modernized transmission, is expected to occur over the next two decades. The expected electricity needs in Ontario and efficient means to satisfy them are described in this plan.

Unconstrained energy resource development in the Rocky Mountain west is likely to threaten the environment and the health and well-being of the people. Impacts may be associated with visibility degradation, toxic concentrations of gases, and deposition of acidic or toxic substances. Because the possible benefits of energy development in the region are very large, there is great concern that constraints imposed by air quality regulation may preclude the use of important resources or make unduly expensive energy produced from the region. The conflict between energy and clean air in the region is exacerbated by non-energy sources, such as copper smelters and urban areas, that already pose significant environmental threats. The hard policy question is not how to preserve clean air resources or how to develop energy but how to achieve and balance both goals. The effects and regulatory costs and benefits of air pollution control are discussed, and policy directions to protect air quality while pursuing energy development are presented

Separations Technology for Clean Water and Energy

Energy Technology Data Exchange (ETDEWEB)

Jarvinen, Gordon D [Los Alamos National Laboratory

2012-06-22

Providing clean water and energy for about nine billion people on the earth by midcentury is a daunting challenge. Major investments in efficiency of energy and water use and deployment of all economical energy sources will be needed. Separations technology has an important role to play in producing both clean energy and water. Some examples are carbon dioxide capture and sequestration from fossil energy power plants and advanced nuclear fuel cycle scemes. Membrane separations systems are under development to improve the economics of carbon capture that would be required at a huge scale. For nuclear fuel cycles, only the PUREX liquid-liquid extraction process has been deployed on a large scale to recover uranium and plutonium from used fuel. Most current R and D on separations technology for used nuclear fuel focuses on ehhancements to a PUREX-type plant to recover the minor actinides (neptunium, americiu, and curium) and more efficiently disposition the fission products. Are there more efficient routes to recycle the actinides on the horizon? Some new approaches and barriers to development will be briefly reviewed.

Measures of International Manufacturing and Trade of Clean Energy Technologies

2017-05-25

The technologies that produce clean energy, such as solar photovoltaic panels and lithium ion batteries for electric vehicles, are globally manufactured and traded. As demand and deployment of these technologies grows exponentially, the innovation to reach significant economies of scale and drive down energy production costs becomes less in the technology and more in the manufacturing of the technology. Manufacturing innovations and other manufacturing decisions can reduce costs of labor, materials, equipment, operating costs, and transportation, across all the links in the supply chain. To better understand the manufacturing aspect of the clean energy economy, we have developed key metrics for systematically measuring and benchmarking international manufacturing of clean energy technologies. The metrics are: trade, market size, manufacturing value-added, and manufacturing capacity and production. These metrics were applied to twelve global economies and four representative technologies: wind turbine components, crystalline silicon solar photovoltaic modules, vehicle lithium ion battery cells, and light emitting diode packages for efficient lighting and other consumer products. The results indicated that clean energy technologies are being developed via complex, dynamic, and global supply chains, with individual economies benefiting from different technologies and links in the supply chain, through both domestic manufacturing and global trade.

Alternative Energy Development and China's Energy Future

Energy Technology Data Exchange (ETDEWEB)

Zheng, Nina; Fridley, David

2011-06-15

In addition to promoting energy efficiency, China has actively pursued alternative energy development as a strategy to reduce its energy demand and carbon emissions. One area of particular focus has been to raise the share of alternative energy in China’s rapidly growing electricity generation with a 2020 target of 15% share of total primary energy. Over the last ten years, China has established several major renewable energy regulations along with programs and subsidies to encourage the growth of non-fossil alternative energy including solar, wind, nuclear, hydro, geothermal and biomass power as well as biofuels and coal alternatives. This study thus seeks to examine China’s alternative energy in terms of what has and will continue to drive alternative energy development in China as well as analyze in depth the growth potential and challenges facing each specific technology. This study found that despite recent policies enabling extraordinary capacity and investment growth, alternative energy technologies face constraints and barriers to growth. For relatively new technologies that have not achieved commercialization such as concentrated solar thermal, geothermal and biomass power, China faces technological limitations to expanding the scale of installed capacity. While some alternative technologies such as hydropower and coal alternatives have been slowed by uneven and often changing market and policy support, others such as wind and solar PV have encountered physical and institutional barriers to grid integration. Lastly, all alternative energy technologies face constraints in human resources and raw material resources including land and water, with some facing supply limitations in critical elements such as uranium for nuclear, neodymium for wind and rare earth metals for advanced solar PV. In light of China’s potential for and barriers to growth, the resource and energy requirement for alternative energy technologies were modeled and scenario analysis

For decades, America has anticipated the transformational impact of clean energy technologies. But even as costs fell and technology matured, a clean energy revolution always seemed just out of reach. Critics often said a clean energy future would "always be five years away." This report focuses on four technology revolutions that are here today. In the last five years they have achieved dramatic reductions in cost and this has been accompanied by a surge in consumer, industrial and commercial deployment. Although these four technologies still represent a small percentage of their total market, they are growing rapidly. The four key technologies this report focuses on are: onshore wind power, polysilicon photovoltaic modules, LED lighting, and electric vehicles.

The Clean Energy Ministerial (CEM) is a high-level global forum to share best practices and promote policies and programs that advance clean energy technologies and accelerate the transition to a global clean energy economy. The CEM works to increase energy efficiency, expand clean energy supply, and enhance clean energy access worldwide. To achieve these goals, the CEM pursues a three-part strategy that includes high-level policy dialogue, technical cooperation, and engagement with the private sector and other stakeholders. Each year, energy ministers and other high-level delegates from the 23 participating CEM governments come together to discuss clean energy, review clean energy progress, and identify tangible next steps to accelerate the clean energy transition. The U.S. Department of Energy, which played a crucial role in launching the CEM, hosted the first annual meeting of energy ministers in Washington, DC, in June 2010. The United Arab Emirates hosted the second Clean Energy Ministerial in 2011, and the United Kingdom hosted the third Clean Energy Ministerial in 2012. In April 2013, India hosted the fourth Clean Energy Ministerial (CEM4) in New Delhi. Key insights from CEM4 are summarized in the report. It captures the ideas and recommendations of the government and private sector leaders who participated in the discussions on six discussion topics: reducing soft costs of solar PV; energy management systems; renewables policy and finance; clean vehicle adoption; mini-grid development; and power systems in emerging economies.

Energy storage deployment and innovation for the clean energy transition

The clean energy transition requires a co-evolution of innovation, investment, and deployment strategies for emerging energy storage technologies. A deeply decarbonized energy system research platform needs materials science advances in battery technology to overcome the intermittency challenges of wind and solar electricity. Simultaneously, policies designed to build market growth and innovation in battery storage may complement cost reductions across a suite of clean energy technologies. Further integration of R&D and deployment of new storage technologies paves a clear route toward cost-effective low-carbon electricity. Here we analyse deployment and innovation using a two-factor model that integrates the value of investment in materials innovation and technology deployment over time from an empirical dataset covering battery storage technology. Complementary advances in battery storage are of utmost importance to decarbonization alongside improvements in renewable electricity sources. We find and chart a viable path to dispatchable US$1 W-1 solar with US$100 kWh-1 battery storage that enables combinations of solar, wind, and storage to compete directly with fossil-based electricity options.

Policies, programs, and current status of alternate energy and global warming concerns in the United States are reported. The U.S. General Accounting Office has issued a report critical of many respects of the Department of Energy's Clean Coal Technology Program. The General Accounting Office points out that 15 of the 32 active projects are behind schedule, over budget, or have been scaled back due to equipment troubles. At a meeting of October 30 on the selection of projects for the round five of the Clean Coal Program, it was asserted that emphasis be placed on longer-term, high efficiency technologies but not on methods that offer near-term reduction of SOx and NOx. The fourth negotiating session of the United Nations-sponsored committee charged with drafting a framework climate convention is taking place in Geneva on December 9-20. With the 1992 United Nations Conference on Environment and Development in Brazil drawing closer, there are indications that a draft treaty should be written in many languages to reflect the concerns of nations opposed to mandating greenhouse gas emissions reductions.

This is a NEDO (New Energy and Industrial Technology Development Organization) report of January 1990, based on a Koleda Childress and Company of EPA report. Comments are made on the development status of fossil and synthetic fuels in the U.S. In the Department of Energy budget, emphasis is placed on environments, science, and national security, and the budget for fiscal 1991 is 17.5 times 1 billion dollars which is 6% higher than the ordinary level. In Round 3 of the Clean Coal Technology Program, the Department of Energy has selected 13 programs for negotiations. NEDO has completed its national energy strategy draft. What attracts attention is the synthetic fuel as an alternative fuel. It is expected that coal, oil shale, and tar sand will be the raw materials. Combined cycle power generation is recommended for coal gasification. As for indirect coal liquefaction, technology of conversion to syngas will be accelerated. In the future, the direct coal liquefaction product will compete with oil in terms of cost. Oil shale retorting and tar sand processing are taken up. Recent global warming measures and energy forecast into 2010 are shown. (NEDO)

weighed again showing typical contaminant deposition levels of approximately 0.00300g per part. They were then cleaned by the solvent or process being tested and then weighed a third time which allowed for the calculation of the cleaning efficiency of the test solvent or process.Based on preliminary experiments, five solvents (ethanol, isopropanol, acetone, ethyl acetate, and tert-butyl acetate) were down selected for further testing. When coupled with ultrasonic agitation, these solvents removed hydrocarbon contaminants as well as Vertrel MCA and showed improved removal of perfluorinated greases. Supercritical carbon dioxide did an excellent job dissolving each of the five contaminants but did a poor job of removing Teflon particles found in the perfluorinated greases. Plasma cleaning efficiency was found to be dependent on which supply gas was used, exposure time, and gas pressure. Under optimized conditions it was found that breathing air, energized to the plasma phase, was able to remove nearly 100% of the contamination.These findings indicate that alternative cleaning methods are indeed able to achieve precision levels of cleanliness. Currently, our team is working with a commercial cleaning company to get independent verification of our results. We are also evaluating the technical and financial aspects of scaling these processes to a size capable of supporting the future cleaning needs of KSC.

Survey/analysis were made on the details of the plan on the leading introduction of clean energy vehicle by 632 transporters who applied for the project on promotion of clean energy vehicle in FY 2001. As a result of the survey, the following were made clear. The clean energy vehicles to be planned to be introduced by transporters are all natural gas vehicles. The transporters planning the leading introduction are mostly in large cities and are spreading also in the periphery. Fifty three percent of the transporters predicts that the predicted average running distance of the clean energy vehicle to be introduced is the same as those of the vehicles they owns, and 39% predicts that it is shorter. About the form of utilization, they use it overwhelmingly for the regional collection/delivery. It is considered that the improvement in running distance per 1 fuel filling of clean energy vehicle will contribute to the spread. Fuel supply stations that the clean energy cars to be introduced use concentrate in the good location. It is necessary to strongly promote preparation of the infrastructure. (NEDO)

Energy system aspects of hydrogen as an alternative fuel in transport

International Nuclear Information System (INIS)

Ramesohl, Stephan; Merten, Frank

2006-01-01

Considering the enormous ecological and economic importance of the transport sector the introduction of alternative fuels-together with drastic energy efficiency gains-will be a key to sustainable mobility, nationally as well as globally. However, the future role of alternative fuels cannot be examined from the isolated perspective of the transport sector. Interactions with the energy system as a whole have to be taken into account. This holds both for the issue of availability of energy sources as well as for allocation effects, resulting from the shift of renewable energy from the stationary sector to mobile applications. With emphasis on hydrogen as a transport fuel for private passenger cars, this paper discusses the energy systems impacts of various scenarios introducing hydrogen fueled vehicles in Germany. It identifies clear restrictions to an enhanced growth of clean hydrogen production from renewable energy sources (RES). Furthermore, it points at systems interdependencies that call for a priority use of RES electricity in stationary applications. Whereas hydrogen can play an increasing role in transport after 2030 the most important challenge is to exploit short-mid-term potentials of boosting car efficiency

Modelling energy demand for a fleet of hydrogen-electric vehicles interacting with a clean energy hub

International Nuclear Information System (INIS)

Syed, F.; Fowler, M.; Wan, D.; Maniyali, Y.

2009-01-01

This paper details the development of an energy demand model for a hydrogen-electric vehicle fleet and the modelling of the fleet interactions with a clean energy hub. The approach taken is to model the architecture and daily operation of every individual vehicle in the fleet. A generic architecture was developed based on understanding gained from existing detailed models used in vehicle powertrain design, with daily operation divided into two periods: charging and travelling. During the charging period, the vehicle charges its Electricity Storage System (ESS) and refills its Hydrogen Storage System (HSS), and during the travelling period, the vehicle depletes the ESS and HSS based on distance travelled. Daily travel distance is generated by a stochastic model and is considered an input to the fleet model. The modelling of a clean energy hub is also presented. The clean energy hub functions as an interface between electricity supply and the energy demand (i.e. hydrogen and electricity) of the vehicle fleet. Finally, a sample case is presented to demonstrate the use of the fleet model and its implications on clean energy hub sizing. (author)

States implement clean energy-related economic development policy to spur innovation, manufacturing, and to address other priorities. This report focuses on those policies most directly related to expanding new and existing manufacturing. The extent to which states invest in this policymaking depends on political drivers and jurisdictional economic development priorities. To date, no one source has collected all of the clean energy-related economic development policies available across the 50 states. Thus, it is unclear how many policies exist within each state and how these policies, when implemented, can drive economic development. Establishing the baseline of existing policy is a critical first step in determining the potential holistic impact of these policies on driving economic growth in a state. The goal of this report is to document the clean energy-related economic development policy landscape across the 50 states with a focus on policy that seeks to expand new or existing manufacturing within a state. States interested in promoting clean energy manufacturing in their jurisdictions may be interested in reviewing this landscape to determine how they compare to peers and to adjust their policies as necessary. This report documents over 900 existing clean energy-related economic development laws, financial incentives (technology-agnostic and clean energy focused), and other policies such as agency-directed programs and initiatives across the states.

Framework for Evaluating the Total Value Proposition of Clean Energy Technologies

Energy Technology Data Exchange (ETDEWEB)

Pater, J. E.

2006-02-01

Conventional valuation techniques fail to include many of the financial advantages of clean energy technologies. By omitting benefits associated with risk management, emissions reductions, policy incentives, resource use, corporate social responsibility, and societal economic benefits, investors and firms sacrifice opportunities for new revenue streams and avoided costs. In an effort to identify some of these externalities, this analysis develops a total value proposition for clean energy technologies. It incorporates a series of values under each of the above categories, describing the opportunities for recapturing investments throughout the value chain. The framework may be used to create comparable value propositions for clean energy technologies supporting investment decisions, project siting, and marketing strategies. It can also be useful in policy-making decisions.

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.

1992-01-01

Chlorofluorocarbons (CFCS) have been used as blowing agents in foam insulation, as the working fluids in cooling and refrigeration equipment, and as solvents in general and precision cleaning applications since their introduction in the 1930s. The number of applications and volumes of CFCs used grew at a tremendous pace during the 1960s and 1970s, but in the mid-1980s it was confirmed that these extremely useful chemicals contribute to the destruction of stratospheric zone and that they are the primary cause of the CFCs have also been found to be second only to carbon dioxide as a factor causing increased greenhouse warming. These chemicals are being phased out of use rapidly to protect the ozone layer and it is very important that the replacements for CFCs do not result in a net increase in global warming by introducing less efficient processes that lead to higher energy use and increased carbon dioxide emissions. A study was conducted to identify those alternative chemicals and technologies that could replace CFCs in energy related applications before the year 2000, and to assess the total potential impact of those alternatives on global warming. The analysis for this project included an estimate of the direct effects from the release of blowing agents, refrigerants, and solvents into the atmosphere and the indirect effects of carbon dioxide emissions resulting from energy use for commercial and residential building insulation, household and commercial refrigeration, building and automobile air conditioning, and general metal and electronics solvent cleaning. This paper focuses on those aspects of the study relevant to building insulation. In general the hydrofluorocarbon (HFC) and hydrochlorofluorocarbon alternatives for CFCs lead to large and sometimes dramatic reductions in total equivalent warming impact, lifetime equivalent C0 2 emissions (TEWI). Most of the reductions result from decreased direct effects without significant changes in energy use

From October 1, 2009 through September 30, 2013 (“contract period”), the Northeast Clean Energy Application Center (“NE-CEAC”) worked in New York and New England (Connecticut, Rhode Island, Vermont, Massachusetts, New Hampshire, and Maine) to create a more robust market for the deployment of clean energy technologies (CETs) including combined heat and power (CHP), district energy systems (DES), and waste heat recovery (WHR) systems through the provision of technical assistance, education and outreach, and strategic market analysis and support for decision-makers. CHP, DES, and WHR can help reduce greenhouse gas emissions, reduce electrical and thermal energy costs, and provide more reliable energy for users throughout the United States. The NE-CEAC’s efforts in the provision of technical assistance, education and outreach, and strategic market analysis and support for decision-makers helped advance the market for CETs in the Northeast thereby helping the region move towards the following outcomes: Reduction of greenhouse gas emissions and criteria pollutants; Improvements in energy efficiency resulting in lower costs of doing business; Productivity gains in industry and efficiency gains in buildings; Lower regional energy costs; Strengthened energy security; Enhanced consumer choice; Reduced price risks for end-users; and Economic development effects keeping more jobs and more income in our regional economy Over the contract period, NE-CEAC provided technical assistance to approximately 56 different potential end-users that were interested in CHP and other CETs for their facility or facilities. Of these 56 potential end-users, five new CHP projects totaling over 60 MW of install capacity became operational during the contract period. The NE-CEAC helped host numerous target market workshops, trainings, and webinars; and NE-CEAC staff delivered presentations at many other workshops and conferences.

The designated successor to fossil fuels is nuclear fission/fusion and that turns out to be problematic. Alternative Energy Systems have great potential but political forces seem to be hampering their development and introduction. The technologies are flexible in their use and scale of operation. The learning curve will not be short but neither will it be as long and as costly as nuclear power. It is time that this is recognised and some serious rethinking takes place in what presently passes for energy policies both in the industrialised countries and in the Third World. Alternative energy systems are defined and some of them which are relevant to the United Kingdom are discussed. (author)

Alternative energy sources or integrated alternative energy systems? Oil as a modern lance of Peleus for the energy transition

International Nuclear Information System (INIS)

Szklo, Alexandre; Schaeffer, Roberto

2006-01-01

In this viewpoint, we discuss the importance of consorting alternative energy sources with oil, and not of opposing them. That is why we introduce the concept of alternative energy systems, which we feel is broader-ranging and more effective than alternative energy sources, as this deals with the actual transformation process of the global energy system. Alternative energy systems integrate oil with other energy sources and pave the way for new systems, which will benefit from what we call the 'virtues of oil'. They produce energy carriers for multi-fuel and multi-product strategies, where flexibility is a key target, allied to other co-benefits, especially those related to the increased use of renewable energy sources. The concept of alternative energy systems can bring a new light to the oil transition era discussion and might also influence energy policies for promoting renewables

Energy Efficient in-Sensor Data Cleaning for Mining Frequent Itemsets

Directory of Open Access Journals (Sweden)

Jacques M. BAHI

2012-03-01

Full Text Available Limited energy, storage, computational power represent the main constraint of sensor networks. Development of algorithms that take into consideration this extremely demanding and constrained environment of sensor networks became a major challenge. Communicating messages over a sensor network consume far more energy than processing it and mining sensors data should respect the characteristics of sensor networks in terms of energy and computation constraints, network dynamics, and faults. This lead us to think of a data cleaning pre processing phase to reduce the packet size transmitted and prepare the data for an efficient and scalable data mining. This paper introduces a tree-based bi-level periodic data cleaning approach implemented on both the source node and the aggregator levels. Our contribution in this paper is two folds. First we look on a periodic basis at each data measured and periodically clean it while taking into consideration the number of occurrences of the measures captured which we shall call weight. Then, a data cleaning is performed between groups of nodes on the level of the aggregator, which contains lists of measures along with their weights. The quality of the information should be preserved during the in-network transmission through the weight of each measure captured by the sensors. This weight will constitute the key optimization of the frequent pattern tree. The result set will constitute a perfect training set to mine without higher CPU consumption allowing us to send only the useful information to the sink. The experimental results show the effectiveness of this technique in terms of energy efficiency and quality of the information by focusing on a periodical data cleaning while taking into consideration the weight of the data captured.

Energy and global warming impacts of CFC alternative technologies

Chlorofluorocarbons (CFCs) are used in a number of applications, and volumes of CFCs used grew at a tremendous pace during the 1960s and 1970s. However, in the mid-1980s, it was confirmed that these extremely useful chemicals contribute to the destruction of stratospheric ozone. These chemicals are being phased out of use rapidly to protect the ozone layer and it is very important that the replacements for CFSs do not result in a net increase in global warming by introducing less efficient processes that lead to higher energy use and increased carbon dioxide emissions. A study was conducted to identify those alternative chemicals and technologies that could replace CFCs in energy related applications before the year 2000, and to assess the total potential impact of these alternatives on global warming. The analysis for this project included an estimate of the direct effects from the release of blowing agents, refrigerants, and solvents into the atmosphere and the indirect effects in the form of carbon dioxide emissions resulting from energy use for commercial and residential heating and cooling, household and commercial refrigeration, building and automobile air-conditioning, and general metal and electronics solvent cleaning. The discussion in this paper focuses on those aspects of the study relevant to refrigeration and air-conditioning. In general the use of hydrofluorocarbon (HFC) and hydrochlorofluorocarbon (HCFC) alternatives for CFCs lead to large and sometimes dramatic reduction in total equivalent warming impact (TEWI), lifetime equivalent CO 2 emission. Most of the reductions result from decreased direct effects without significant changes in energy use. 3 refs., 3 figs., 1 tab

Depletion of fossil oil deposits and the escalating threat of global warming have put clean energy research, which includes the search for clean energy carriers such as hydrogen and methane as well as the reduction of carbon dioxide emissions, on the urgent agenda. A significant technical challenge has been recognized as the development of a viable method to efficiently trap hydrogen, methane and carbon dioxide gas molecules in a confined space for various applications.

In this feature article we provide an overview of the current status of clean energy applications of porous MOFs, including hydrogen storage, methane storage and carbon dioxide capture.

Investigation of Alternative Approaches for Cleaning Mott Porous Metal Filters

International Nuclear Information System (INIS)

Poirier, M.R.

2003-01-01

The Department of Energy selected Caustic Side Solvent Extraction (CSSX) as the preferred cesium removal technology for Savannah River Site (SRS) waste. As a pretreatment step for the CSSX flowsheet, the incoming salt solution that contains entrained sludge is contacted with monosodium titanate (MST) to adsorb strontium and select actinides. The resulting slurry is filtered to remove the sludge and MST. Filter fouling occurs during this process. At times, personnel can increase the filtrate rate by backpulsing or scouring. At other times, the filtrate rate drops significantly and only chemical cleaning will restore filter performance. The current baseline technology for filter cleaning uses 0.5 M oxalic acid. The Salt Processing Project (SPP) at SRS, through the Tanks Focus Area, requested an evaluation of other cleaning agents to determine their effectiveness at removing trapped sludge and MST solids compared with the baseline oxalic acid method. A review of the technical literature identified compounds that appear effective at dissolving solid compounds. Consultation with the SPP management team, engineering personnel, and researchers led to a selection of oxalic acid, nitric acid, citric acid, and ascorbic acid for testing. Tests used simulated waste and actual waste as follows. Personnel placed simulated or actual SRS High Level Waste sludge and MST in a beaker. They added the selected cleaning agents, stirred the beakers, and collected supernate samples periodically analyzing for dissolved metals

Since 1973, the oil prices have increased tenfold. Currently we are already short by 7% in energy demand which is increasing in an exponential order. Also environmental problems associated with conventional energy generation need a serious consideration as a concept of clean energy. Various sources available are as follows. 1) coal energy 2) hydroelectric 3) nuclear energy. In India, thermal power obtained from amounts to 72.8%, hydroelectric amounts to 25.3% and nuclear about 2 to 3%. Non-conventional energy sources are mostly non-polluting except for the fact that no economically viable methods are invented to harness the power effectively. Following are the non-conventional energy resources. 1) solar energy:- this can be applied in different ways. 1) photothermal, 2) photovoltaics, 3) photosynthesis, 4) bio-energy. ii) wind energy, iii) ocean energy iv) geothermal energy. It can be concluded that nuclear energy is the only way out to current situation. Energy conservation and energy consciousness should also be implemented. (author)

1995-11-01

The Support for Eastern European Democracy (SEED) Act of 1989 directed the U.S. Department of Energy (DOE) to undertake an equipment assessment project aimed at developing the capability within Poland to manufacture or modify industrial-scale combustion equipment to utilize fossil fuels cleanly. This project is being implemented in the city of Krakow as the `Krakow Clean Fossil Fuels and Energy Efficiency Project.` Funding is provided through the U.S. Agency for International Development (AID). The project is being conducted in a manner that can be generalized to all of Poland and to the rest of Eastern Europe. The historic city of Krakow has a population of 750,000. Almost half of the heating energy used in Krakow is supplied by low-efficiency boilerhouses and home coal stoves. Within the town, there are more than 1,300 local boilerhouses and 100,000 home stoves. These are collectively referred to as the `low emission sources` and they are the primary sources of particulates and hydrocarbon emissions in the city and major contributors of sulfur dioxide and carbon monoxide.

Energy: the solar hydrogen alternative

Energy Technology Data Exchange (ETDEWEB)

Bocheris, J O.M.

1977-01-01

The author argues that nuclear and solar energy should begin replacing conventional fossil sources as soon as possible because oil, gas and even coal supplies will be depleted within decades. A hydrogen economy would introduce major technical problems but its chief benefits are that it permits energy storage in a post fossil fuel era when electricity is expected to play a major role. It can be converted to electricity, cleanly and efficiently with fuel cells and in liquid form can be burnt as jet fuel. Hydrogen can also be burnt in internal combustion engines although less efficiently in fuel cells. However, although hydrogen is clean and efficient, technical development is still needed to reduce its cost and to cope with safety problems. The book contains a wealth of technical information and is a valuable reference on a topic of growing importance.

Low-carbon energy innovation is essential to combat climate change, promote economic competitiveness, and achieve energy security. Using U.S. patent data and additional patent-relevant data collected from the Internet, we map the landscape of low-carbon energy innovation in the United States since 1975. We isolate 10,603 renewable and 10,442 traditional energy patents and develop a database that characterizes proxy measures for technical and commercial impact, as measured by patent citations and Web presence, respectively. Regression models and multivariate simulations are used to compare the social, institutional, and geographic drivers of breakthrough clean energy innovation. Results indicate statistically significant effects of social, institutional, and geographic variables on technical and commercial impacts of patents and unique innovation trends between different energy technologies. We observe important differences between patent citations and Web presence of licensed and unlicensed patents, indicating the potential utility of using screened Web hits as a measure of commercial importance. We offer hypotheses for these revealed differences and suggest a research agenda with which to test these hypotheses. These preliminary findings indicate that leveraging empirical insights to better target research expenditures would augment the speed and scale of innovation and deployment of clean energy technologies.

With the increasing concerns about the environment, energy producers and governments are looking at developing clean energy sources. However, Turkey has limited clean energy resources and is using low grade coal which has high sulphur content as an alternative energy source. The aim of this paper is to study the possibility of generating clean fuel from Edirne Lignite and to get a better understanding of chemical mechanisms involved in coal leaching with hydrofluoric acid (HF) solutions. Leaching was conducted on Edirne Lignite with HF solution at ambient temperature and the effects of parameters such as reaction time and concentration of acid solutions on the process were evaluated. The optimum conditions were found and it was shown that ash levels can be reduced from 28.9% to 10.5% and the calorific value increased by 500kcal/kg with the HF leaching method. This study demonstrated that the production of clean fuel from high sulphur lignite is possible.

2015-11-01

Full Text Available Water management has recently become a major concern for many countries. During the last century consumption of water and energy has been increased in the world. This trend is anticipated to continue in the decades to come. One of the greatest reasons is the unplanned industrial activities deteriorating environment in the name of rising standard of life. What is needed is the avoidance of environmental pollution and maintenance of natural balance, in the context of sustainable development. However, Turkey’s geographical location has several advantages for extensive use of most of the renewable energy resources. There is a large variation in annual precipitation, evaporation and surface run-off parameters, in Turkey. Precipitation is not evenly distributed in time and space throughout the country. There are 25 hydrological basins in Turkey. But the rivers often have irregular regimes. In this situation the main aim is to manage and use the water resources for renewable, sustainable and clean energy. This paper deals with water management for renewable, sustainable and clean energy in Turkey.

Alternative energy sources: ECC report

International Nuclear Information System (INIS)

Renwick, Lord; Stoddart, Lord; Lauderdale, Earl of

1988-01-01

The European Communities Committee Report on Alternative Energy Resources was debated. Six alternative energy sources were first described - wind power, biomass, geothermal energy, solar energy, wave and tidal power. Combined heat and power was also mentioned. General questions concerning alternative energy sources were then considered. In particular, their potential contribution to the energy demand was assessed. The evidence presented to the committee suggested that they would only make a small contribution in the near future and could not be considered as a substitute for coal and nuclear power. However, by the year 2030 it would be possible for 18% of the national electricity demand to be met by alternative energy sources. The economic and environmental issues were assessed briefly and the report's conclusions were summarized. An independent review of wave power was called for in view of conflicting evidence presented to the committee. The debate which followed lasted three hours and is reported verbatim. Other issues raised included energy conservation, public attitudes to energy, the environment, government and private funding of research and development of nuclear power, including fusion. (U.K.)

An assessment of alternatives for replacing Freon 113 in bench type electrical circuit board cleaning at Fermi National Accelerator Laboratory

International Nuclear Information System (INIS)

Isakson, K.; Vessell, A.L.

1994-07-01

Fermilab is presently phasing out all solvents containing Freon-113 (CFC-113) as part of the continuing Waste Minimization Program. These solvents are used primarily in cleaning the flux off of electronic circuit boards after soldering, specifically in bench type work. Title VI of the Clean Air Act mandates a production phase-out for ozone depleting substances, like CFC-113, by the year 2000. Our study addresses this issue by evaluating and choosing alternative non-CFC solvents to replace the CFC-1 13 solvents at Fermilab. Several potential non-CFC cleaning solvents were tested. The evaluation took place in three parts: controlled experimental evaluation, chemical composition evaluation, and employee performed evaluation. First, we performed a controlled nine-step procedure with the potential solvents where each was evaluated in categories such as cleaning effectiveness, odor, residue, type of output and drying time. Next, we listed the chemical composition of each solvent. We noted which solvents contained hydrochlorofluorocarbons because they are targeted for phase-out in the future and will be recognized as interim solutions only. Finally, after preliminary testing, five solvents were chosen as the best options. These solvents were sent to be tested by Fermilab employees who use such materials. Their opinions are valuable not only because they are knowledgeable in this field, but also because they will be using the solvents chosen to replace the CFC-113 solvents. The results favored two ''best alternatives'': Safezone Solvent Flux Remover by Miller-Stephenson and E-Series CFC Free Flux-Off 2000 by Chemtech. Another possible solution also pursued is the no-clean solder option. In our study, we were not able to thoroughly investigate the many types of no-clean solders because of time and financial constraints. The testing that was done, however, showed that no-clean solder was a viable alternative in many cases

This report summarizes task 1 of the Clean Air Heat Pump project - modelling and simulation on energy savings when using the clean air heat pump for ventilation, air cleaning and energy recovery. The total energy consumption of the proposed ventilation systems using clean air heat pump technology was calculated by a theoretical model and compared with the reference ventilation systems (conventional ventilation systems). The energy compared between the two systems includes energy used for heating, cooling and fan. The simulation and energy saving calculation was made for the application of the clean air heat pump in three typical climate conditions, i.e. mild-cold, mild-hot and hot and wet climates. Real climate data recorded from three cities in 2002 was used for the calculation. The three cities were Copenhagen (Denmark), Milan (Italy) and Colombo (Sir Lanka) which represent the above three typical climate zones. For the Danish climate (the mild cold climate), the calculations show that the ventilation system using clean air heat pump technology can save up to 42% of energy cost in winter compared to the conventional ventilation system. The energy saving in summer can be as high as 66% for the ventilation system with humidity control and 9% for the ventilation system without the requirement of humidity control. Since the Danish summer climate is very mild, over 80% of the yearly energy consumption for ventilation is used during winter season. It is, therefore, estimated that more than 35% annual energy saving for ventilation is expected in Denmark using the clean air heat pump ventilation technology. For the mild hot climate, e.g. the Italian climate, the calculations show that up to 63% of the energy saving can be achieved in summer season. For the winter mode, 17% reduction of the energy cost can be expected for the domestic use. For industrial use, the energy cost of the clean air heat pump may not be favourable due to the industrial price of gas in Italy is

The US–China Clean Energy Research Center (CERC) was launched in 2009 by US Energy Secretary Steven Chu, Chinese Minister of Science and Technology Wan Gang, and Chinese National Energy Agency Administrator Zhang Guobao. This 5-year collaboration emerged from the fact that the United States and China are the world’s largest energy producers, energy consumers, and greenhouse gas emitters, and that their joint effort could have significant positive repercussions worldwide. CERC’s main goal is to develop and deploy clean energy technologies that will help both countries meet energy and climate challenges. Three consortia were established to address the most pressing energy-related research areas: Advanced Coal Technology, Clean Vehicles, and Building Energy Efficiency (BEE). The project discussed in this report was part of the CERC-BEE consortia; its objective was to lower energy use in buildings by developing and evaluating technologies that improve the cost-effectiveness of air barrier systems for building envelopes.

Policies, programs, and current status of alternate energy and global warming concerns in the United States are reported. The House Ways and Means Committee has added a number of energy-related tax incentives to the omnibus energy policy bill approved by the Energy and Commerce Committee earlier this year. The U.S. Department of Energy has issued a request for project proposals to participate in Round 5 of the Clean Coal Technology Program, focusing on innovative, high-efficiency combustion technologies that will help meet future generation needs. The Department of Energy, furthermore, will receive proposals to reduce greenhouse gas CO2 and toxic gas emissions as well as SO{sub 2} and NO{sub 2} emissions. President George Bush has announced that he will attend the United Nations Conference on Environment and Development (UNCED) in Rio de Janeiro, Brazil, next month. President Bush stated last month that he would not sign at the UNCED any agreement that does not protect the environment and the economy of the U.S. Extended negotiations yielded a draft climate framework treaty with no binding greenhouse gas emissions reduction or timetables.

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

China's power generating capacity has increased markedly in recent years largely due new coal-fired power stations, but sadly, the environmental consequences were largely ignored. Apart from the coal used for power generation, coal is also used to fuel industrial boilers and in houses: some of the world's most polluted cities are in China. In the late 1990s, China began to curb the environmental impact by closing smaller power stations and retrofitting clean-up plant to the bigger stations, but there is still a lot of cleaning-up still to do. The government of China is now offering incentives for the development of renewable sources of energy, and wind power is seen as a clean and sustainable solution to the air pollution problem. The government has identified various geographical regions suitable for wind farms. Solar energy is also seen as a promising source of energy and is being employed in areas remote from power grids. The paper discusses incentives and bank loans for the development and application of renewables

Proposed federal clean energy initiatives and climate legislation have suggested significant increases to federal funding for clean energy deployment and investment. Many states and utilities have over a decade of experience and spend billions of public dollars every year to support EE/RE deployment through programs that reduce the cost of technologies, provide financing for EE/RE projects, offer technical assistance, and educate market participants. Meanwhile, constraints on public expenditures at all levels of government continue to call upon such programs to demonstrate their value. This report reviews the results of these programs and the specific financial incentives and financing tools used to encourage clean energy investment. Lessons from such programs could be used to inform the future application of EE/RE incentives and financing tools. These lessons learned apply to use of distributed resources and the historical focus of these EE/RE programs.

Cabraal, A.

1997-12-01

The author discusses efforts by the Asia Alternative Energy Unit (ASTAE) of the World Bank in supporting alternative energy source projects in Asia. Energy growth rates have been as high as 18% per year, with power capacity doubling each decade in the 1960`s, 70`s and 80`s. Much of this has come from fossil fuel projects coupled with major hydroelectric projects. One consequence is developing air pollution loads originating in Asia. ASTAE has been supporting pilot programs in applying alternative energy sources. The goal has been to mainstream renewable energy sources in World Bank operations, by working with managers from different countries to: include renewable energy in country assistance strategies and sectorial development plans; provide assistance to renewable energy initiatives; expand initiatives to new countries, sectors and technologies.

Alternative energy review

1991-09-01

A review is presented of electricity generation technologies which are considered to be alternatives to more conventional technologies. The review is limited to those technologies which have application in Ontario, and provides descriptions, technical and economic assessments, environmental information, and forecasts of potential use of solar energy, wind energy, fuel cells, biomass energy, peat, and municipal solid wastes. Of these technologies, only municipal solid waste combustion is economically viable under current conditions, but government policies prohibit the implementation of new facilities. Certain photovoltaic and wind energy technologies are being found viable for remote sites unconnected to the power grid. Wood waste combustion is viable in the forest products industry. The total potential contribution of these six alternative technologies to Ontario's energy production is forecast at under 190 MW to a range of 685-1,465 MW by the year 2005, according to three different scenarios. The technologies showing the greatest future promise are fuel cells, photovoltaics, and biomass. Except for municipal waste combustion, cost continues to be a significant barrier to utility-scale application of alternative generation technologies in Ontario. However, private individuals and corporations (non-utility generators) may adopt some of these technologies in the absence of access to the power grid, in cogeneration applications, or for demonstration purposes. 120 refs., 79 figs., 93 tabs

Coffman, Makena; Griffin, James P.; Bernstein, Paul

2012-01-01

This paper quantifies the relative cost-savings of utilizing a greenhouse gas emissions-weighted Clean Energy Standard (CES) in comparison to a Renewable Portfolio Standard (RPS). Using a bottom-up electricity sector model for Hawaii, this paper demonstrates that a policy that gives “clean energy” credit to electricity technologies based on their cardinal ranking of lifecycle GHG emissions, normalizing the highest-emitting unit to zero credit, can reduce the costs of emissions abatement by up to 90% in comparison to a typical RPS. A GHG emissions-weighted CES provides incentive to not only pursue renewable sources of electricity, but also promotes fuel-switching among fossil fuels and improved generation efficiencies at fossil-fired units. CES is found to be particularly cost-effective when projected fossil fuel prices are relatively low. - Highlights: ► Proposes a GHG Emissions-Weighted Clean Energy Standard (CES) mechanism. ► Compares CES to RPS using a case study of Hawaii. ► Finds CES is up to 90% more cost-effective as a GHG abatement tool.

Off-momentum collimation and cleaning in the energy ramp in the LHC

CERN Document Server

Quaranta, Elena; Giulini Castiglioni Agosteo, Stefano Luigi Maria

This Master thesis work has been carried out at CERN in the framework of the LHC (Large Hadron Collider) Collimation project. The LHC is a two-beam proton collider, built to handle a stored energy of 360MJ for each beam. Since the energy deposition from particle losses could quench the superconducting magnets, a system of collimators has been installed in two cleaning insertions in the ring and in the experimental areas. The achievable LHC beam intensity is directly coupled to the beam loss rate and, consequently, to the cleaning eciency of the collimation system. This study analyses the collimation cleaning performance in dierent scenarios inside the accelerator. First, simulations are performed of the transverse losses in the LHC collimation system during the acceleration process. The results are compared with data taken during a dedicated session at the LHC machine. Simulations are also performed to predict the collimation eciency during future operation at higher energy. Furthermore, an investigation of t...

Alternatives to nuclear energy

Terrado, E.N.

1981-01-01

This article discusses several possibilities as alternatives to nuclear energy and their relevance to the Philippine case. The major present and future fuel alternatives to petroleum and nuclear energy are coal, geothermal heat, solar energy and hydrogen, the first two of which are being used. Different conversion technologies are also discussed for large scale electricity production namely solar thermal electric conversion (STC), photovoltaic electric power system (PEPS) and ocean thermal energy conversion (OTEC). Major environmental considerations affect the choice of energy sources and technologies. We have the problem of long term accumulation of radioactive waste in the case of nuclear energy; in geothermal and fossil-fuels carbon dioxide uranium and accumulation may cause disastrous consequences. With regard to Philippine option, the greatest considerations in selecting alternative energy options would be resources availability - both energy and financial and technology status. For the country's energy plan, coal and geothermal energy are expected to play a significant role. The country's coal resources are 1.4 billion metric tons. For geothermal energy, 25 volcanic centers were identified and has a potential equivalent to 2.5 x 10 6 million barrels of oil. Solar energy if harnessed, being in the sunbelt, averaging some 2000 hours a year could be an energy source. The present dilemma of the policy maker is whether national resources are better spent on large scale urban-based energy projects or whether those should be focused on small scale, rural oriented installations which produced benefits to the more numerous and poorer members of the population.

Full Text Available Self-cleaning concrete is an effective alternative to provide cleaner environment which contribute to sustainability and towards a green environment. It is in accordance with the requirements of environmental issues on huge energy consumption and air pollution from carbon dioxide (CO2 emissions. Photocatalyst in self-cleaning concrete accelerates the decomposition of organic particulates, hence pollution could be reduced through photocatalytic degradation of gaseous pollutants. Mechanical performances of self-cleaning concrete were improved by adding photocatalytic materials. Self cleaning abilities were evaluated in the photocatalytic activity test under UV light and photocatalytic degradation of gaseous pollutant was measured by depollution test. This review aims to give an overview about the characteristics of photocatalytic materials and mechanical performances of self-cleaning concrete.

It is accepted that coal will continue to play the major role in the supply of energy to the country for the remainder of the century. In this paper, however, emphasis has been directed to those options which could supplement coal in an economic and technically sound manner. The general conclusion is that certain forms of solar energy hold the most promise and it is in this direction that research, development and implementation programmes should be directed. Tidal energy, fusion energy, geothermal energy, hydrogen energy and fuel cells are also discussed as alternative energy options

The boom of clean energies in China

Seaman, J.

2009-01-01

The author outlines the strong current development of wind and solar energy in China, with an increasing and already rather high wind energy production, and a solar panel production which is, until now, mostly exported. He observes that the development of these industries is based on economic, political and security issues: China is now strongly dependent on energy imports (even coal imports), looks to reduce the social cost of pollution and environment degradation, and wants to be a major actor of the renewable energy sector. The development of this sector is mainly financed by public investments, but the clean sector is weakened by the slow development of distribution networks, and by a too fragmented production market. The author discusses the new approach adopted by the Chinese government to overcome these drawbacks, and the consequences of this approach for the international context

2013-01-01

The generation of electricity in Brazil is concentrated in hydroelectric generation, renewable and clean source, but that does not satisfy all the demand and leads to necessity of a supplementary thermal sources portion. Considering the predictions of increase in demand for electricity in the next years, it becomes necessary to insert new sources to complement the production taking into account both the volume being produced and the needs of environmental preservation. Thus, nuclear power can be considered a potential supplementary source for electricity generation in Brazil as well as the country has large reserves of fissile material, the generation emits no greenhouse gases, the country has technological mastery of the fuel cycle and it enables the production of large volumes of clean energy. The objective of this study is to demonstrate the potential of nuclear energy in electricity production in Brazil cleanly and safely, ensuring the supplies necessary to maintain the country's economic growth and the increased demand sustainable. For this, will be made an analysis of economic and social indicators of the characteristics of our energy matrix and the availability of our sources, as well as a description of the nuclear source and arguments that justify a higher share of nuclear energy in the matrix of the country. Then, after these analysis, will notice that the generation of electricity from nuclear source has all the conditions to supplement safely and clean supply of electricity in Brazil. (author)

Despite a prevalence of peer-reviewed scientific research and high-level reports by intergovernmental agencies (e.g., IPCC) that document changes in our climate and consequences for human societies, the public discourse regards these topics as controversial and sensitive. The chasm between scientific-based understanding of climate systems and public understanding can most easily be addressed via high quality, science-based education on these topics. Well-trained and confident educators are required to provide this education. However, climate science and energy awareness are complex topics that are rapidly evolving and have a great potential for controversy. Furthermore, the interdisciplinary nature of climate science further increases the difficulty for teachers to stay abreast of the science and the policy. Research has shown that students and educators alike hold misconceptions about the climate system in general and the causes and effects of climate change in particular. The NSF-funded CLEAN Pathway (http://cleanet.org) as part of the National Science Digital Library (http://www.nsdl.org) strives to address these needs and help educators address misconceptions by providing high quality learning resources and professional development opportunities to support educators of grade levels 6 through 16. The materials focus on teaching climate science and energy use. The scope and framework of the CLEAN Pathway is defined by the Essential Principles of Climate Science (CCSP, 2009) and the Energy Literacy Principles recently developed by the Department of Energy. Following this literacy-based approach, CLEAN helps with developing mental models to address misconceptions around climate science and energy awareness through a number of different avenues. These are: 1) Professional development opportunities for educators - interactive webinars for secondary teachers and virtual workshops for college faculty, 2) A collection of scientifically and pedagogically reviewed, high

Interest in alternative motor vehicle fuels has grown tremendously over the last few years. The 1990 Clean Air Act Amendments, the National Energy Policy Act of 1992 and the California Clean Air Act are primarily responsible for this resurgence and have spurred both the motor fuels and vehicle manufacturing industries into action. For the first time, all three U.S. auto manufacturers are offering alternative fuel vehicles to the motoring public. At the same time, a small but growing alternative fuels refueling infrastructure is beginning to develop across the country. Although the recent growth in alternative motor fuels use is impressive, their market niche is still being defined. Environmental regulations, a key driver behind alternative fuel use, is forcing both car makers and the petroleum industry to clean up their products. As a result, alternative fuels no longer have a lock on the clean air market and will have to compete with conventional vehicles in meeting stringent future vehicle emission standards. The development of cleaner burning gasoline powered vehicles has signaled a shift in the marketing of alternative fuels. While they will continue to play a major part in the clean vehicle market, alternative fuels are increasingly recognized as a means to reduce oil imports. This new role is clearly defined in the National Energy Policy Act of 1992. The Act identifies alternative fuels as a key strategy for reducing imports of foreign oil and mandates their use for federal and state fleets, while reserving the right to require private and municipal fleet use as well.

Both secondary energies, electricity and hydrogen, have much in common: they are technology driven; both are produced from any available primary energy; once produced both are environmentally and climatically clean over the entire length of their respective conversion chains, from production to utilization; they are electrochemically interchangeable via electrolyses and fuel cells; both rely on each other, e.g., when electrolyzers and liquefiers need electricity or when electricity-providing low temperature fuel cells need hydrogen; in cases of secondary energy transport over longer distances they compete with each other; in combined fossil fuel cycles both hydrogen and electricity are produced in parallel exergetically highly efficiently; hydrogen in addition to electricity helps exergizing the energy system and, thus, maximizing the available technical work. There are dissimilarities, too: electricity transports information, hydrogen does not; hydrogen stores and transports energy, electricity does not (in macroeconomic terms). The most obvious dissimilarity is their market presence, both in capacities and in availability: Electricity is globally ubiquitous (almost), whilst hydrogen energy is still used in only selected industrial areas and in much smaller capacities. The article describes in 15 chapters, 33 figures, 3 tables, and 2 Annexes the up-and-coming hydrogen energy economy, its environmental and climatic relevance, its exergizing influence on the energy system, its effect on decarbonizing fossil fueled power plants, the introduction of the novel non-heat-engine-related electrochemical energy converter fuel cell in portable electronics, in stationary and mobile applications. Hydrogen guarantees environmentally and climatically clean transportation on land, in air and space, and at sea. Hydrogen facilitates the electrification of vehicles with practically no range limits.

Clean energy is more and more required worldwide in proportion to actualization of global environmental issues including global warming. Therefore, it is an urgent task to realize promotion of worldwide introduction of clean energy which exists abundantly and is widely distributed in the world, such as hydropower and solar energy, while reducing the dependence on fossil fuel. However, since the renewable energy, differing from so called fossil fuel, is impossible to transport for long distance and store as it is, its utilization is subject to be limited. As one possible resolution of this kind of issues, 'International clean energy network using hydrogen conversion technology' which enables conversion of renewable energy from low cost hydropower into hydrogen energy and also into the transportable and storable form, is a meaningful concept. This system technology enables dealing of this hydrogen energy in international market as in the same manner as fossil fuel. It is considered to enable promotion of international and large scale introduction of such clean energy, along with the contribution to diversified and stabilized international energy supply. In this study, based upon the above-mentioned point of view and assumption of two sites, one on supply side and another on demand side of hydrogen energy, three systems are presumed. One of the systems consists of liquid hydrogen as transportation and storage medium of hydrogen, and the others intermediately convert hydrogen into methanol or ammonia as an energy carrier. A overall conceptual design of each system spanning from hydrogen production to its utilization, is conducted in practical way in order to review the general technical aspects and economical aspects through cost analysis. This study is administrated through the New Energy and Industrial Technology Development Organization (NEDO) as a part of the International Clean Energy Network Using Hydrogen Conversion (so-called WE-NET) Program with funding from

Evaluating the impacts of the clean cities program.

Science.gov (United States)

Qiu, Shiyong; Kaza, Nikhil

The Department of Energy's Clean Cities program was created in 1993 to reduce petroleum usage in the transportation sector. The program promotes alternative fuels such as biofuels and fuel-saving strategies such as idle reduction and fleet management through coalitions of local government, non-profit, and private actors. Few studies have evaluated the impact of the program because of its complexity that include interrelated strategies of grants, education and training and diversity of participants. This paper uses a Difference-in-Differences (DiD) approach to evaluate the effectiveness of the program between 1990 and 2010. We quantify the effectiveness of the Clean Cities program by focusing on performance measures such as air quality, number of alternative fueling stations, private vehicle occupancy and transit ridership. We find that counties that participate in the program perform better on all these measures compared to counties that did not participate. Compared to the control group, counties in the Clean Cities program experienced a reduction in days with bad air quality (3.7%), a decrease in automobile commuters (2.9%), an overall increase in transit commuters (2.1%) and had greater numbers of new alternative fueling stations (12.9). The results suggest that the program is a qualified success. Copyright © 2016 Elsevier B.V. All rights reserved.

More than half of the electricity produced in the southeastern states is fuelled by coal. Although the region produces some coal, most of the states depend heavily on coal imports. Many of the region's aging coal power facilities are planned for retirement within the next 20 years. However, estimates indicate that a 20% increase in capacity is needed over that time to meet the rapidly growing demand. The most common incentives for energy efficiency in the Southeast are loans and rebates; however, total public spending on energy efficiency is limited. The most common state-level policies to support renewable energy development are personal and corporate tax incentives and loans. The region produced 1.8% of the electricity from renewable resources other than conventional hydroelectricity in 2009, half of the national average. There is significant potential for development of a biomass market in the region, as well as use of local wind, solar, methane-to-energy, small hydro, and combined heat and power resources. Options are offered for expanding and strengthening state-level policies such as decoupling, integrated resource planning, building codes, net metering, and interconnection standards to support further clean energy development. Benefits would include energy security, job creation, insurance against price fluctuations, increased value of marginal lands, and local and global environmental paybacks.

One of the pillars that holds up the stability and economic development of our society is the need to ensure a reliable and affordable supply of energy that meets our current energy needs. The high dependence on fossil fuels, our main source of primary energy, has many drawbacks mainly caused by greenhouse gases. It is urgent to address this unsustainable energy future through innovation, adoption of new energy alternatives and better use of existing technologies. In this context, hydrogen associated to renewable energy is probably an important part of that future. This paper presents a real demonstrator of energy generation and storage through the clean production of hydrogen from small wind energy. Thus, this demonstrator will allow the study of the technical and econonmic feasibility of hydrogen production. Wind energy will be stored as hydrogen for a later use. In this way hydrogen represents a form of no-loss energy battery. The use of small wind energy allows a more modular and scattered production even in developing countries. In this way, we avoid the transport of hydrogen and the electricity to produce it, improving system efficiency. Moreover, small wind systems require a lower initial investment in infrastructure which will facilitate the development of a separate market for hydrogen production. (orig.)

Energy supply is essential in the development of Azerbaijan. However, it remains reliant on fossil fuels to supply country's energy demand that leads to the exhaustion of energy resources, while increasing environmental pollution in the region. Analysis of the present situation shows that in order to prevent global disasters we must change the existing energy systems. Azerbaijan must seek new ways of generating energy, which do not sacrifice the natural environment, and which protect the health of the population and which promote sustainable development of the region. International Ecoenergy Academy (IEA) has long been engaged in the development of projects on the use of alternative energy sources. Based on the results of studies we suggested that introduction of modern renewable energy technologies can help reduce the health impacts of air pollution and ecological effects of acid rains, hazards of greenhouse gas emissions and climate changes, while providing people with environmentally clean energy and new job opportunities.

Between 2010 and 2013, the U.S. Department of Energy (DOE) funded the Southeast Clean Energy Application Center (SE-CEAC), co-located at the North Carolina Solar Center at NC State University (NCSU) and at Mississippi State University. The SE-CEAC was one of eight regional CEACs established to promote and assist in transforming the market for combined heat and power (CHP), district energy (DE) and waste heat to power (WHP) throughout the U.S. CHP locates power generation at the point of demand and makes productive use of the residual thermal energy for process and space heating in factories and businesses, thus lowering the cost of meeting electricity and heat requirements and increasing energy efficiency. The overall goal of the SE-CEAC was to support end-user implementation and overall market transformation for CHP and related clean energy technologies. Five objectives were targeted to achieve the goal: 1. Market Analysis and Information Dissemination 2. Outreach and Education for Potential CHP End-users 3. Policy Support for State and Regional Stakeholders 4. Technical Assistance to Support CHP Deployment 5. Collaboration with DOE and other CEACs Throughout the project, the CEACs provided key services of education and outreach, technical assistance and market analysis in support of project objectives. These services were very effective at achieving key objectives of assisting prospective CHP end-users and informing policy makers, utilities and others about the benefits of CHP. There is a marked increase in the awareness of CHP technologies and applications as an energy resource among end-users, policymakers, utility regulators, electric utilities and natural gas utilities in the Southeast region as a result. At the end of 2013, a number of best-practice policies for CHP were applied or under consideration in various Southeast states. The SE-CEAC met its targets for providing technical assistance with over 50 analyses delivered for 412 MW of potential end

Herrera, Hugo Francisco Lopez

As world population grows, and its technology evolves, the demand for electricity inexorably increases. Until now most of this electricity has been produced via fossil fuels, non-renewable energy resources that are irreversibly deteriorating our environment. On the economical aspect it does not get any better. Let's not forget market rules, the higher the demand and lower the offer, the higher the price we will have to pay. Oil is an excellent example. Some countries try to solve this situation with Pharaohnic projects, i.e. investing absurd amounts of money in 'green electricity' building monstrous dams to power equally monstrous hydroelectric power plants. The only problem with this is that it is not green at all---it does have an enormous environmental impact---it is extremely complicated and expensive to implement. It is important to point out, that this research project does not try to solve world's thirst for electricity. It is rather aimed to help solve this problematic at a much lower scale---it should be considered as an extremely small step in the right direction. It focuses on satisfying the local electricity needs with renewable, non-contaminating and locally available resources. More concisely, this project focuses on the attainment and use of hydrogen as an alternate energy source in El Paso/Juarez region. Clean technology is nowadays available to produce hydrogen and oxygen, i.e. the photoelectrolysis process. Photovoltaic cells coupled with electrolytic devices can be used to produce hydrogen and oxygen in a sustainable manner. In this research, simulation models of hybrid systems were designed and developed. They were capable to compare, predict and evaluate different options for hydrogen generation. On the other hand, with the produced hydrogen from the electrolysis process it was possible to generate electricity through fuel cells. The main objectives of the proposed research were to define how to use the resources for the attainment of hydrogen

This paper discussed the fate of Renewable Energy (RE) in Canada. The importance of RE is now increasing from both an environmental and energy security perspective, and has been projected as a key solution to climate change problems. RE is also one of the key greenhouse gas (GHG) mitigation options to be considered under the Clean Development Mechanism (CDM). Canada possesses more than 100 GW of technical potential for RE resources, including wind, solar and small hydro. Less than 10 per cent of this potential has been exploited to date. A number of programs have been developed to facilitate the deployment of Renewable Energy Technologies (RETs), including financial incentives, renewable portfolio standards and green power procurement policies. However, Canadian policies are less aggressive than those of other countries. This study showed that the supply of certified emission reductions (CERs) resulting from negative and low cost CDM options, such as energy efficiency improvements, afforestation and reforestation, could surpass the total demand for CERs during the first commitment period of the Kyoto Protocol. Implementation of RE projects under the CDM could be undermined. It was recommended that increased support of the Global Environment Facility (GEF), use of the Special Climate Change Fund, and special attention to RE from both host and investing countries should become mandatory as alternative strategies to promote RE. In addition, it should be acknowledged that the development of RETs faces a number of barriers and challenges, including competition from conventional energy technologies; lack of customer and investor confidence; regulatory and institutional barriers; and technical barriers such as transmission access. 19 refs., 1 tab

Luis, J; Sidek, L M; Desa, M N M; Julien, P Y

2013-01-01

Hydroelectric energy has been in recent times placed as an important future source of renewable and clean energy. The advantage of hydropower as a renewable energy is that it produces negligible amounts of greenhouse gases, it stores large amounts of electricity at low cost and it can be adjusted to meet consumer demand. This noble vision however is becoming more challenging due to rapid urbanization development and increasing human activities surrounding the catchment area. Numerous studies have shown that there are several contributing factors that lead towards the loss of live storage in reservoir, namely geology, ground slopes, climate, drainage density and human activities. Sediment deposition in the reservoir particularly for hydroelectric purposes has several major concerns due to the reduced water storage volume which includes increase in the risk of flooding downstream which directly effects the safety of human population and properties, contributes to economic losses not only in revenue for power generation but also large capital and maintenance cost for reservoir restorations works. In the event of functional loss of capabilities of a hydropower reservoir as a result of sedimentation or siltation could lead to both economical and environmental impact. The objective of this paper is aimed present the importance of hydropower as a source of renewable and clean energy in the national energy mix and the increasing challenges of sustainability.

Modern engineered materials, components and systems depend on raw materials whose properties provide essential functionality to these technologies. Some of these raw materials are subject to supply-chain risks, and such materials are known as critical materials. This paper reviews corporate, national and world perspectives on material criticality. It then narrows its focus to studies that assess "what is critical" to clean-energy technologies. The focus on supply-chain risks is not meant to be alarmist but rather to encourage attention to monitoring these risks and pursuing technological innovation to mitigate the risks.

Manitoba currently generates 5500 MW of electricity, and has the potential to add another 5000 MW of clean energy. Nearly 2000 MW of Manitoba's electricity is currently being sold to the United States. New transmission sites will ensure both grid reliability and energy security for Ontario, and power exchanges are expected to reduce costs. This presentation provided details of a memorandum of understanding (MOU) between Ontario and Manitoba concerning energy sales across existing and future transmission infrastructure. Peak energy sales were expected to reach 1000 MW in the near future. Options for the interconnection included direct high voltage direct current (HVDC) lines to Sudbury as well as lines through Thunder Bay and Winnipeg. Manitoba's existing hydro sites were outlined, and potential sites were reviewed. In addition to presenting new supply options, this presentation described generation and transmission approval processes, as well as construction schedules for new sites and interconnection points. It was concluded that while there is currently a provincial focus on electricity supply and demand, new generation technologies will make interprovincial electricity agreements economically viable. tabs., figs

An electrical vehicle environment was established to promote research and technology development in the area of high power energy management. The project incorporates a topology that permits parallel development of an alternative energy delivery system and an energy storage system. The objective of the project is to develop technologies, specifically power electronics, energy storage electronics and controls that provide efficient and effective energy management between electrically powered devices in alternative energy vehicles plugin electric vehicles, hybrid vehicles, range extended vehicles, and hydrogen-based fuel cell vehicles. In order to meet the project objectives, the Vehicle Energy Management System (VEMS) was defined and subsystem requirements were obtained. Afterwards, power electronics, energy storage electronics and controls were designed. Finally, these subsystems were built, tested individually, and integrated into an electric vehicle system to evaluate and optimize the subsystems performance. Phase 1 of the program established the fundamental test bed to support development of an electrical environment ideal for fuel cell application and the mitigation of many shortcomings of current fuel cell technology. Phase 2, continued development from Phase 1, focusing on implementing subsystem requirements, design and construction of the energy management subsystem, and the integration of this subsystem into the surrogate electric vehicle. Phase 2 also required the development of an Alternative Energy System (AES) capable of emulating electrical characteristics of fuel cells, battery, gen set, etc. Under the scope of the project, a boost converter that couples the alternate energy delivery system to the energy storage system was developed, constructed and tested. Modeling tools were utilized during the design process to optimize both component and system design. This model driven design process enabled an iterative process to track and evaluate the impact

The testing presented in this report is in support of the investigation of the Alternative Chemical Cleaning program to aid in developing strategies and technologies to chemically clean radioactive High Level Waste tanks prior to tank closure. The data and conclusions presented here were the examination of the corrosion rates of A285 carbon steel and 304L stainless steel when interacted with the chemical cleaning solution composed of 0.18 M nitric acid and 0.5 wt. % oxalic acid. This solution has been proposed as a dissolution solution that would be used to remove the remaining hard heel portion of the sludge in the waste tanks. This solution was combined with the HM and PUREX simulated sludge with dilution ratios that represent the bulk oxalic cleaning process (20:1 ratio, acid solution to simulant) and the cumulative volume associated with multiple acid strikes (50:1 ratio). The testing was conducted over 28 days at 50°C and deployed two methods to invest the corrosion conditions; passive weight loss coupon and an active electrochemical probe were used to collect data on the corrosion rate and material performance. In addition to investigating the chemical cleaning solutions, electrochemical corrosion testing was performed on acidic and basic solutions containing sodium permanganate at room temperature to explore the corrosion impacts if these solutions were to be implemented to retrieve remaining actinides that are currently in the sludge of the tank.

The US steel industry, in order to maintain its basic iron production, is thus moving to lower coke requirements and to the cokeless or direct production of iron. The US Department of Energy (DOE), in its Clean Coal Technology programs, has encouraged the move to new coal-based technology. The steel industry, in its search for alternative direct iron processes, has been limited to a single process, COREX{reg_sign}. The COREX{reg_sign} process, though offering commercial and environmental acceptance, produces a copious volume of offgas which must be effectively utilized to ensure an economical process. This volume, which normally exceeds the internal needs of a single steel company, offers a highly acceptable fuel for power generation. The utility companies seeking to offset future natural gas cost increases are interested in this clean fuel. The COREX{reg_sign} smelting process, when integrated with a combined cycle power generation facility (CCPG) and a cryogenic air separation unit (ASU), is an outstanding example of a new generation of environmentally compatible and highly energy efficient Clean Coal Technologies. This combination of highly integrated electric power and hot metal coproduction, has been designated CPICOR{trademark}, Clean Power from Integrated Coal/Ore Reduction.

The Lansing Community College Alternative Energy Center was created with several purposes in mind. The first purpose was the development of educational curricula designed to meet the growing needs of advanced energy companies that would allow students to articulate to other educational institutions or enter this growing workforce. A second purpose was the professional development of faculty and teachers to prepare them to train tomorrow's workforce and scholars. Still another purpose was to design, construct, and equip an alternative energy laboratory that could be used for education, demonstration, and public outreach. Last, the Center was to engage in community outreach and education to enhance industry partnerships, inform decision makers, and increase awareness and general knowledge of hydrogen and other alternative energy technologies and their beneficial impacts on society. This project has enabled us to accomplish all of our goals, including greater faculty understanding of advanced energy concepts, who are now able to convey this knowledge to students through a comprehensive alternative energy curriculum, in a facility well-equipped with advanced technologies, which is also being used to better educate the public on the advantages to society of exploring alternative energy technologies.

Energy Revolution. A Sustainable Pathway to a Clean Energy Future for Europe. A European Energy Scenario for EU-25

Teske, S.; Baker, C.

2005-09-01

Greenpeace and the Institute of Technical Thermodynamics, Department of Systems Analysis and Technology Assessment of the German Aerospace Center (DLR),have developed a blueprint for the EU energy supply that shows how Europe can lead the way to a sustainable pathway to a clean energy future. The Greenpeace energy revolution scenario demonstrates that phasing out nuclear power and massively reducing CO2-emissions is possible. The scenario comes close to a fossil fuels phase-out by aiming for a 80% CO2 emissions reduction by 2050.The pathway in this scenario achieves this phase-out in a relatively short time-frame without using technological options (such as 'clean coal') that are ultimately dead ends, deflecting resources from the real solutions offered by renewable energy. Whilst there are many technical options that will allow us to meet short-term EU Kyoto targets (-8% GHG by 2010), these may have limited long-term potential. The Greenpeace Energy Revolution Scenario shows that in the long run, renewable energy will be cheaper than conventional energy sources and reduce EU's dependence from world market prices from imported fossil and nuclear fuels.The rapid growth of renewable energy technologies will lead to a large investment in new technologies.This dynamic market growth will result in a shift of employment opportunities from conventional energy-related industries to new occupational fields in the renewable energy industry. Renewable energy is expected to provide about 700,000 jobs in the field of electricity generation from renewable energy sources by 2010

Despite substantial regulations for nearly two decades, attainment of this ambient standards for ozone and carbon monoxide (CO) remain difficult goals to achieve, Even with of ozone precursors and CO. The 1990 Amendments to the Clean Air Act (CAA90) prescribe further reductions of mobile source emissions. One such reduction strategy is using clean fuels, such as methanol, ethanol, or other alcohols (in blends of 85 percent or more alcohol with gasoline or other fuel), reformulated gasoline or diesel, natural gas, liquified petroleum gas, hydrogen, or electricity. There are regulatory measures involving special fuels which will be required in areas heavily polluted with ozone and CO. The state of Colorado recently passed the 1992 Air Pollution Prevention and Control Act which included provisions for the use of alternative fuels which will be implemented in 1994. In addition to adhering to the Colorado state regulations, the city and county of Denver also have regulations pertaining to the use of alternative fuels in fleets of 10 or more vehicles. Denver's program began in 1992. This paper will address the issue of fleet conversion and its impact on industry in Colorado, and Denver in particular

2008-03-01

This study was conducted to develop market intelligence related to clean energy technologies in Northern California, including both commercial and demonstration technologies. The study was developed as a tool for exploring engagement between Canadian and Californian businesses and partnering opportunities. The study examined technologies for solar power and photovoltaics; hydrogen and fuel cells; and waste-to-energy. A list of more than 150 organizations, government agencies, business associations, and utilities was prepared. The survey also included the establishment of contact points with large facilities, public spaces, bus fleets, and major capital projects. Fifty-nine interviews were also conducted as part of the study. Results of the study indicated that the biggest challenge concerning most individuals was the need to reduce energy consumption while maintaining reliability. Many interviewees expressed an interest in operating waste-to-energy facilities. Fifty interviewees indicated that they were planning to use or already used solar technologies. An analysis of clean energy needs was also included. The study indicated that many local governments are reluctant to embrace new, highly visible technologies. Only sophisticated organizations with unique energy demands have considered the use of fuel cell technologies. 1 fig

The Clean-Development Mechanism, stochastic permit prices and energy investments

International Nuclear Information System (INIS)

Hieronymi, Philipp; Schüller, David

2015-01-01

We analyze the impact on energy investments stemming from different emission permit classes, by considering permits that are allocated inside the European Emission Trading Scheme and secondary Certified Emission Reduction (sCER) permits originating from the Clean Development Mechanism. One price taking firm which is subject to emission regulation has the choice to invest in gas or wind power plant. The firm faces uncertainty regarding stochastically evolving permit prices, while it receives a premium on the electricity price for wind energy. As a first step, we determine the value of the option to invest into a gas power plant over time. Then, we calculate the investment probability of a gas power investment in a range of policy scenarios. We find that allowing the usage of sCER permits in the present policy framework has a positive impact on gas power investment. Decoupling the price processes has a similar effect. If the quota of sCER permits is doubled, the decrease in the investment probability for wind power is large. We carry out sensitivity tests for different parameter values, and find that investment behavior changes significantly with differing interest rates, the wind energy premium and volatility. - Highlights: • We model the impact of two CO 2 permit classes on energy investments. • We present a real-options framework accounting for uncertainty. • Clean Development Mechanism permits have a negative influence on investment into renewable energy. • Interest rate and volatility values have a strong impact on the results

The Washoe Tribe of Nevada and California was awarded funding to complete the Washoe Tribe Alternative Energy Feasibility Study project. The main goal of the project was to complete an alternative energy feasibility study. This study was completed to evaluate “the potential for development of a variety of renewable energy projects and to conduct an alternative energy feasibility study that determines which alternative energy resources have the greatest economic opportunity for the Tribe, while respecting cultural and environmental values” (Baker-Tilly, 2014). The study concluded that distributed generation solar projects are the best option for renewable energy development and asset ownership for the Washoe Tribe. Concentrating solar projects, utility scale wind projects, geothermal, and biomass resource projects were also evaluated during the study and it was determined that these alternatives would not be feasible at this time.

Clean energy funds: An overview of state support for renewable energy

Energy Technology Data Exchange (ETDEWEB)

Bolinger, Mark; Wiser, Ryan

2001-04-01

Across the United States, as competition in the supply and delivery of electricity has been introduced, states have sought to ensure the continuation of ''public benefits'' programs traditionally administered or funded by electric utilities. Many states have built into their restructuring plans methods of supporting renewable energy sources. One of the most popular policy mechanisms for ensuring such continued support has been the system-benefits charge (SBC), a non-bypassable charge to electricity customers (usually applied on a cents/kWh basis) used to collect funds for public purpose programs. Thus far, at least fourteen states have established SBC funds targeted in part towards renewable energy. This paper discusses the status and performance of these state renewable or ''clean'' energy funds supported by system-benefits charges. As illustrated later, existing state renewable energy funds are expected to collect roughly $3.5 billion through 2012 for renewable energy. Clearly, these funds have the potential to provide significant support for clean energy technologies over at least the next decade. Because the level of funding for renewable energy available under these programs is unprecedented and because fund administrators are developing innovative and new programs to fund renewable projects, a certain number of program failures are unavoidable. Also evident is that states are taking very different approaches to the distribution of these funds and that many lessons are being learned as programs are designed, implemented, and evaluated. Our purpose in this paper is therefore to relay early experience with these funds and provide preliminary lessons learned from that experience. It is our hope that this analysis will facilitate learning across states and help state fund managers develop more effective and more coordinated programs. Central to this paper are case studies that provide information on the SBC-funded renewable

Solubility testing with actual High Level Waste tank sludge has been conducted in order to evaluate several alternative chemical cleaning technologies for the dissolution of sludge residuals remaining in the tanks after the exhaustion of mechanical cleaning and sludge sluicing efforts. Tests were conducted with archived Savannah River Site (SRS) radioactive sludge solids that had been retrieved from Tank 5F in order to determine the effectiveness of an optimized, dilute oxalic/nitric acid cleaning reagent toward dissolving the bulk non-radioactive waste components. Solubility tests were performed by direct sludge contact with the oxalic/nitric acid reagent and with sludge that had been pretreated and acidified with dilute nitric acid. For comparison purposes, separate samples were also contacted with pure, concentrated oxalic acid following current baseline tank chemical cleaning methods. One goal of testing with the optimized reagent was to compare the total amounts of oxalic acid and water required for sludge dissolution using the baseline and optimized cleaning methods. A second objective was to compare the two methods with regard to the dissolution of actinide species known to be drivers for SRS tank closure Performance Assessments (PA). Additionally, solubility tests were conducted with Tank 5 sludge using acidic and caustic permanganate-based methods focused on the “targeted” dissolution of actinide species.

As a part of the WE-NET project, the introduction condition of hydrogen as substituting energy and CO2 reduction effect were analyzed using a global energy model. The WE-NET project aims at global-wide introduction of clean energy by converting abundant renewable clean energy into hydrogen transportable to distant consumers all over the world. The study result in fiscal 1996 is as follows. Undeveloped hydroelectric resources in the world are estimated to be 12 trillion kWh/y equivalent to the existing developed one in the world. Since the cost of the hydroelectric power generation projects over 1000MW in the planning stage is estimated to be 0.02-0.05$/kWh lower than that of other renewable energies, such projects are expected as energy source in the initial stage of the practical WE-NET project. The GREEN model was modified by adding a hydrogen analysis function, and extending an analysis period. The modified model allowed evaluation of the long-term important role of hydrogen energy, in particular, the capability of CO2 gas reduction all over the world. 28 refs., 92 figs., 56 tabs.

Southeast Regional Clean Energy Policy Analysis (Revised)

Energy Technology Data Exchange (ETDEWEB)

McLaren, J.

2011-04-01

More than half of the electricity produced in the southeastern states is fuelled by coal. Although the region produces some coal, most of the states depend heavily on coal imports. Many of the region's aging coal power facilities are planned for retirement within the next 20 years. However, estimates indicate that a 20% increase in capacity is needed over that time to meet the rapidly growing demand. The most common incentives for energy efficiency in the Southeast are loans and rebates; however, total public spending on energy efficiency is limited. The most common state-level policies to support renewable energy development are personal and corporate tax incentives and loans. The region produced 1.8% of the electricity from renewable resources other than conventional hydroelectricity in 2009, half of the national average. There is significant potential for development of a biomass market in the region, as well as use of local wind, solar, methane-to-energy, small hydro, and combined heat and power resources. Options are offered for expanding and strengthening state-level policies such as decoupling, integrated resource planning, building codes, net metering, and interconnection standards to support further clean energy development. Benefits would include energy security, job creation, insurance against price fluctuations, increased value of marginal lands, and local and global environmental paybacks.

Ruiter, J P [N. V. Kema te Arnhem, NL

1975-01-01

A review of alternative energy sources is presented. Solar energy may be used by collecting the heat for direct use or by converting it to electricity. Flat-plate and concentrating collectors are described. Wind energy is an indirect form of solar energy, and has been used for many years in the Netherlands. Calculations of the efficiency of windmills, and of the useful available wind energy along the Netherlands' coastline, are provided. The conversion of organic waste to useable energy is described, including techniques of pyrolysis, combustion, and biological conversion. Tidal energy and ocean-thermal-gradient power plants are briefly described. Geothermal energy is a particularly attractive resource. The average temperature gradient is about 30/sup 0/C/km, ranging from 10/sup 0/C/km in South Africa to 150/sup 0/C/km in Italy. In the Netherlands it ranges from 20-50/sup 0/C/km. The various types of geothermal systems (steam, water, geopressured) are reviewed, and presently operating geothermal power plants are described. A comparison is made of the costs of various energy sources, and 27 references are provided.

Remick, C.

2017-12-01

The U.S.-China Clean Energy Research Center - Water and Energy Technologies (CERC-WET) is a global research partnership focused on developing and deploying technologies that to allow the U.S. and China to thrive in a future with constrained energy and water resources in a changing global climate. This presentation outlines and addresses the opportunities and challenges for international research collaboration on the so called "water-energy nexus", with a focus on industrial partnership, market readiness, and intellectual property. The U.S. Department of Energy created the CERC program as a research and development partnership between the United States and China to accelerate the development and deployment of advanced clean energy technologies. The United States and China are not only the world's largest economies; they are also the world's largest energy producers and energy consumers. Together, they account for about 40% of annual global greenhouse gas emissions. The bilateral investment in CERC-WET will total $50 million over five years and will target on the emerging issues and cut-edge research on the topics of (1) water use reduction at thermoelectric plants; (2) treatment and management of non-traditional waters; (3) improvements in sustainable hydropower design and operation; (4) climate impact modeling, methods, and scenarios to support improved understanding of energy and water systems; and (5) data and analysis to inform planning and policy.

This paper describes the methodologies and data used for estimating the complex-wide impacts of alternative strategies for conducting remediation of all DOE sites and facilities, but does not address issues relating to Waste Management capabilities. Clean-up strategies and their corresponding goals for contaminated media may be driven by concentration-based regulatory standards, land-use standards (e.g., residential, industrial, wild life reserve, or totally restricted), risk-based standards, or other standards determined through stakeholder input. Strategies implemented to achieve these goals usually require the deployment of (a) clean-up technologies to destroy, remove, or contain the contaminants of concern; (b) institutional controls to prevent potential receptors from coming into contact with the contaminants; or (c) a combination of the above

Market failures and barriers as a basis for clean energy policies

Brown, M.A.

2001-01-01

This paper provides compelling evidence that large-scale market failures and barriers prevent consumers in the United States from obtaining energy services at least cost. Assessments of numerous energy policies and programs suggest that public interventions can overcome many of these market obstacles. By articulating these barriers and reviewing the literature on ways of addressing them, this paper provides a strong justification for the policy portfolios that define the ''Scenarios for a Clean Energy Future'', a study conducted by five National Laboratories. These scenarios are described in other papers published in this special issue of Energy Policy. (author)

The purpose of this paper is to reiterate what might be considered basic principles for promoting clean and efficient energy. These principles have very important implications for the design of energy supply and transportation facilities, but they go far beyond that to unify such design with the design, use and maintenance of many other types of facilities and goods. These principles also affect the way we consider energy security in the context of sustainable development. In annex, this paper presents the recommendation of the Council, with a list of environmentally favourable energy options. (TEC). 2 refs., Annex

Worrell, Ernst; Price, Lynn

2001-01-01

Scenarios for a Clean Energy Future (CEF) studied the role that efficient clean energy technologies can play in meeting the economic and environmental challenges for our future energy supply. The study describes a portfolio of policies that would motivate energy users and businesses to invest in innovative energy efficient technologies. On the basis of the portfolios, two policy scenarios have been developed, i.e. a moderate scenario and an advanced scenario. We focus on the industrial part of the CEF-study. The studied policies include a wide scope of activities, which are organized under the umbrella of voluntary industrial sector agreements. The policies for the policy scenarios have been modeled using the National Energy Modeling System (CEF-NEMS). Under the reference scenario industrial energy use would grow to 41 Quads in 2020, compared to 34.8 Quads in 1997, with an average improvement of the energy intensity by 1.1% per year. In the Moderate scenario the annual improvement is a bout 1.5%/year, leading to primary energy use of 37.8 Quads in 2020, resulting in 10% lower CO2 emissions by 2020 compared to the reference scenario. In the Advanced scenario the annual improvement increases to 1.8% per year, leading to primary energy use of 34.3 Quads in 2020, and 29% lower CO2 emissions. We report on the policies, assumptions and results for industry

Many forward-looking clean-energy technologies hinge on the development of scalable and efficient membrane-based separations. Ongoing investment in the basic research of microporous materials is beginning to pay dividends in membrane technology maturation. Specifically, improvements in membrane selectivity, permeability, and durability are being leveraged for more efficient carbon capture, desalination, and energy storage, and the market adoption of membranes in those areas appears to be on the horizon. Herein, an overview of the microporous materials chemistry driving advanced membrane development, the clean-energy separations employing them, and the theoretical underpinnings tying membrane performance to membrane structure across multiple length scales is provided. The interplay of pore architecture and chemistry for a given set of analytes emerges as a critical design consideration dictating mass transport outcomes. Opportunities and outstanding challenges in the field are also discussed, including high-flux 2D molecular-sieving membranes, phase-change adsorbents as performance-enhancing components in composite membranes, and the need for quantitative metrologies for understanding mass transport in heterophasic materials and in micropores with unusual chemical interactions with analytes of interest. © 2018 WILEY-VCH Verlag GmbH & Co.

In the context of climate change, no one solution is future-proof. It is going to take a coordinated worldwide effort to find the right mix of energy policies while balancing diverse and sometimes competing priorities. The WLPGA Climate Change Working Group (CCWG) seeks to demonstrate that the technologies needed to continue current rates of development while mitigating climate change already exist and that LP gas can be a major part of today's solutions to this challenge. LP gas is not a zero-GHG fuel. However, in most cases it can make major and immediate contributions to delivering real GHG emissions reductions. In some ways LP Gas can claim to be ahead of its time, for its clean-burning, low-carbon advantage is available at once, so that even using today's technology, most industries can exceed Kyoto GHG reduction targets by switching to LP Gas. The fact is that LP Gas produces lower GHG emissions compared to conventional energy supplies in virtually every application it is used, from stationary applications such as water heating, space heating, cooking and industrial boilers to transportation applications. There are opportunities to switch to clean burning LP gas for virtually every industry as a means meet GHG targets. LP gas is also portable, making it a perfect complement to distributed renewable energy source such as solar, wind and wave energy (and soon the fuel cell), thereby reducing our reliance centrally produced electricity. LP Gas used in combination with these renewable sources also can improve energy reliability while reducing the overall life-cycle costs. The portable and clean burning nature of LP Gas also makes it an ideal substitute for solid fuels in domestic cooking and heating applications. Household solid fuel use, overwhelmingly concentrated in developing countries, accounts for up to 30% of black carbon emissions worldwide according to some statistics. Switching to LP Gas could lower global GHG emissions as well as help to diminish

The efforts aim to develop a CVD (chemical vapor deposition) mechanism cleaning gas with less environmental impact such as global warming and a CVD process using the same. The candidate gas synthesizing study for the development of such a gas continues from the preceding fiscal year. In addition, various candidate gases and tentatively synthesized gases are evaluated for their cleaning performance using a simplified experimental system. As the result, patent applications were filed for three novel alternative gases low in environmental impact and high in cleaning performance. In the research and development of CVD processes, a verification test process is developed for the evaluation of alternative gases at the real system level using a large CVD evaluation system. Studies are also made in which some existing gases are utilized to improve on CVD cleaning efficiency and to reduce greenhouse gas emissions. In relation to the process, one domestic patent application is made, and three essays are presented at an international conference on electrochemistry in the United States. (NEDO)

Clean coal technologies

1993-01-01

According to the World Energy Council (WEC), at the beginning of the next century three main energy sources - coal, nuclear power and oil will have equal share in the world's total energy supply. This forecast is also valid for the USSR which possesses more than 40% of the world's coal resources and continuously increases its coal production (more than 700 million tons of coal are processed annually in the USSR). The stringent environmental regulations, coupled with the tendency to increase the use of coal are the reasons for developing different concepts for clean coal utilization. In this paper, the potential efficiency and environmental performance of different clean coal production cycles are considered, including technologies for coal clean-up at the pre-combustion stage, advanced clean combustion methods and flue gas cleaning systems. Integrated systems, such as combined gas-steam cycle and the pressurized fluidized bed boiler combined cycle, are also discussed. The Soviet National R and D program is studying new methods for coal utilization with high environmental performance. In this context, some basic research activities in the field of clean coal technology in the USSR are considered. Development of an efficient vortex combustor, a pressurized fluidized bed gasifier, advanced gas cleaning methods based on E-beam irradiation and plasma discharge, as well as new catalytic system, are are presented. In addition, implementation of technological innovations for retrofitting and re powering of existing power plants is discussed. (author)

The Phase I LHC Collimation System Upgrade could include moving part of the Betatron Cleaning from LHC Point 7 to Point 3 to improve both operation flexibility and intensity reach. In addition, the partial relocation of beam losses from the current Betatron cleaning region at Point 7 will mitigate the risks of Single Event Upsets to equipment installed in adjacent and partly not sufficient shielded areas. The combined Betatron and Momentum Cleaning at Point 3 implies that new collimators have to be added as well as to implement a new collimator aperture layout. This paper shows the whole LHC Collimator Efficiency variation with the new layout at different beam energies. As part of the evaluation, energy deposition distribution in the IR3 region give indications about the effect of this new implementations not only on the collimators themselves but also on the other beam line elements as well as in the IR3 surrounding areas.

Full Text Available Consumption of alternative energy resources is conventionally considered as an implement of lean management, main target of which is use of renewable (in terms of exhaustibility energy resources. However, when it comes to actual consumption of alternative energy resources, the contradiction is arisen between , the caused need of economy of non-renewable energy resources and rational environmental management and "providence" which is caused by cost reduction of energy consumption. What is the factual providence, how substantial is the dilemma between environmental friendliness and cost effectiveness in matters of energy savings, what is the significance of alternative energy consumption in countries with different economic types, what should balanced solution in energy mentioned issues are contemplated in current article.

The Sequential Probability Ratio Test: An efficient alternative to exact binomial testing for Clean Water Act 303(d) evaluation.

Science.gov (United States)

Chen, Connie; Gribble, Matthew O; Bartroff, Jay; Bay, Steven M; Goldstein, Larry

2017-05-01

The United States's Clean Water Act stipulates in section 303(d) that states must identify impaired water bodies for which total maximum daily loads (TMDLs) of pollution inputs into water bodies are developed. Decision-making procedures about how to list, or delist, water bodies as impaired, or not, per Clean Water Act 303(d) differ across states. In states such as California, whether or not a particular monitoring sample suggests that water quality is impaired can be regarded as a binary outcome variable, and California's current regulatory framework invokes a version of the exact binomial test to consolidate evidence across samples and assess whether the overall water body complies with the Clean Water Act. Here, we contrast the performance of California's exact binomial test with one potential alternative, the Sequential Probability Ratio Test (SPRT). The SPRT uses a sequential testing framework, testing samples as they become available and evaluating evidence as it emerges, rather than measuring all the samples and calculating a test statistic at the end of the data collection process. Through simulations and theoretical derivations, we demonstrate that the SPRT on average requires fewer samples to be measured to have comparable Type I and Type II error rates as the current fixed-sample binomial test. Policymakers might consider efficient alternatives such as SPRT to current procedure. Copyright © 2017 Elsevier Ltd. All rights reserved.

Elk Valley Rancheria; Tribe; renewable energy; energy options analysis. The Elk Valley Rancheria, California ('Tribe') is a federally recognized Indian tribe located in Del Norte County, California, in the northwestern corner of California. The Tribe, its members and Tribal enterprises are challenged by increasing energy costs and undeveloped local energy resources. The Tribe currently lacks an energy program. The Tribal government lacked sufficient information to make informed decisions about potential renewable energy resources, energy alternatives and other energy management issues. To meet this challenge efficiently, the Tribe contracted with Frank Zaino and Associates, Inc. to help become more energy self-sufficient, by reducing their energy costs and promoting energy alternatives that stimulate economic development. Frank Zaino & Associates, Inc. provided a high level economic screening analysis based on anticipated electric and natural gas rates. This was in an effort to determine which alternative energy system will performed at a higher level so the Tribe could reduce their energy model by 30% from alternative fuel sources. The feasibility study will identify suitable energy alternatives and conservation methods that will benefit the Tribe and tribal community through important reductions in cost. The lessons learned from these conservation efforts will yield knowledge that will serve a wider goal of executing energy efficiency measures and practices in Tribal residences and business facilities. Pacific Power is the provider of electrical power to the four properties under review at $ 0.08 per Kilowatt-hour (KWH). This is a very low energy cost compared to alternative energy sources. The Tribe used baseline audits to assess current and historic energy usage at four Rancheria owned facilities. Past electric and gas billing statements were retained for review for the four buildings that will be audited. A comparative assessment of the various

This report seeks to inform decision makers seeking to prioritise RD&D investments in a time of financial uncertainty. It is an update of the December 2009 IEA report Global Gaps in Clean Energy Research, Development and Demonstration, which examined whether rates of LCET investment were sufficient to achieve shared global energy and environmental goals (IEA,2009). It discusses the impact of the green stimulus spending announcements, and provides private sector perspectives on priorities for government RD&D spending. Finally, it includes a revised assessment of the gaps in public RD&D, together with suggestions for possible areas for expanded international collaboration on specific LCETs. The conclusion re-affirms the first Global Gaps study finding that governments and industry need to dramatically increase their spending on RD&D for LCETs.

Alternative energy and environmental concerns

International Nuclear Information System (INIS)

2002-01-01

The New Brunswick Market Design Committee will address environmental concerns within the context of the new energy policy and market rules for the newly restructured electric power industry. The new rules that come with power restructuring will in some ways facilitate environmental protection but they can also complicate it. With open access markets, it will be possible to coordinate evolving energy frameworks with current environmental objectives. Restructuring provides an opportunity to create incentives and guidelines to operate in an environmentally sustainable manner, as suggested in the New Brunswick Energy Policy, White Paper which outlines green pricing, the development of a provincial Climate Change Action Plan, and promotion of alternative energy. The Market Design Committee examined the environmental concerns listed within the White Paper that pertain to the generation and transmission of electricity. These include the integration of energy and environmental policy. Other issues addressed in this report were trans-boundary and global air emissions, the development of a provincial climate change action plan, and a federal-provincial climate change framework agreement. New Brunswick will encourage the development of pilot studies that demonstrate the benefits of renewable and alternative technologies and that help promote the market to manufacture, sell and maintain renewable and alternative technologies in small-scale on-site power generation. This report also discussed the 4 key air pollutants for which specific treatment has been defined, including sulphur dioxide, nitrogen oxides, mercury and carbon dioxide. Recommendations for reducing these emissions include the use of renewable energy sources, the use of lower carbon fuels, increased efficiency of power transmission/generation/distribution systems, reducing power demand by the industrial sector, and promoting energy efficient building codes. 34 refs., 1 tab

Management alternatives of energy wood thinning stands

Heikkilae, Jani; Siren, Matti; Aeijaelae, Olli

2007-01-01

Energy wood thinning has become a feasible treatment alternative of young stands in Finland. Energy wood thinnings have been carried out mainly in stands where precommercial thinning has been neglected and the harvesting conditions for industrial wood thinning are difficult. Despite of its positive effects on harvesting costs and on renewable energy potential, whole-tree harvesting has been constantly criticized for causing growth loss. In this paper, the profitability of energy wood thinning was studied in 20 Scots pine-dominated stands where energy wood thinning was carried out. The growth of the stands after thinning was predicted with the help of Motti-stand simulator. Entire rotation time of the stands was simulated with different management alternatives. The intensity of first thinning and recovery level of logging residues varied between alternatives. In order to attain acceptable harvesting conditions, industrial wood thinning had to be delayed. The effect of energy wood thinning on subsequent stem wood growth was almost the same as in conventional thinning. Whole-tree harvesting for energy proved to be profitable alternative if the stumpage price is around 3EUR m -3 , the interest rate is 3% or 5% and the removal of pulpwood is less than 20 m 3 ha -1 . If the harvestable pulpwood yield is over 20 m 3 ha -1 , integrated harvesting of industrial and energy wood or delayed industrial wood harvesting becomes more profitable. (author)

Coalbed methane (CBM) has the potential to emerge as a significant clean energy resource. It also has the potential to replace other diminishing hydrocarbon reserves. The latest developments in technologies and methodologies are playing a key role in harnessing this unconventional resource. Some of these developments include adaptations of existing technologies used in conventional oil and gas generations, while others include new applications designed specifically to address coal's unique properties. Completion techniques have been developed that cause less damage to the production mechanisms of coal seams, such as those occurring during cementing operations. Stimulation fluids have also been engineered specifically to enhance CBM production. Deep coal deposits that remain inaccessible by conventional mining operations offer CBM development opportunities.

The alternative energy future

1989-02-01

The alternative energy future can be achieved only by making energy conservation programmes successful, and by fully committing to the utilization of soft energy sources. This is the perspective drawn by the author who in this book investigates the fundamentals of an ecologically and socially sound energy policy for the future. Looking at California, USA, where completely near concepts have been put to work in the energy sector since the mid-seventies, the author shows how it can be done, by rewarding energy conserving activities, using available energy sources more efficiently, developing the means for renewable energy exploitation wherever appropriate. A turn in energy policy is feasible also in West Germany, both in technical and political terms. Starting from the experience gained in the USA, the author presents an outline of options and potentials of a new energy strategy for the Federal Republic of Germany. (orig./HP) [de

Impact of the Clean Development Mechanism on wind energy investments in Turkey

Energy Technology Data Exchange (ETDEWEB)

Tunc, Murat; Pak, Ruhan [Yeditepe Univ., Istanbul (Turkey). Systems Engineering Dept.

2012-12-01

As carbon trading continues to be implemented on both a national and an international scale, it is becoming an important factor in renewable energy investment decisions. Turkey, with continuous growth of carbon dioxide emission and energy consumption since 2001, ratified the Kyoto Protocol in 2009 and began registration of projects with greenhouse gas reductions in 2010. In light of these developments, wind energy resources with a potential of 48,000 MW are among the most efficient and effective solutions for clean and sustainable energy in Turkey. The aim of our study is to reveal the importance of the Clean Development Mechanism (CDM) of the Kyoto Protocol on wind energy investment decisions. A broad review of wind energy in Turkey is given, and then, a comprehensive feasibility study of a wind energy firm with a valuation model including Certified Emission Reduction (CER) prices is applied to a case study, the Mega Metallurgy Power. With a holistic and interdisciplinary system engineering approach, results are obtained using comprehensive analysis of technology, emission, and power generation of a wind energy firm linked to a valuation model. This comprehensive model sets the investment decision-making criteria, the enterprise value comparison with total financing. Finally, a sensitivity analysis is run to show that the enterprise value is positively correlated with CER prices. Based on these results, it is concluded that if the world's largest carbon offsetting program, the CDM, prevails after 2012, CER prices will have a positive impact on wind energy firm valuations and related investment decisions.

The purposes, objectives and technology path-ways for alternative energy development are discussed with the aim of reaching sustainable energy development in China. Special attention has been paid to alternative power and alternative vehicle fuels. Instead of limiting alternative energy to energy sources such as nuclear and renewable energy, the scope of discussion is extended to alternative technologies such as coal power with carbon capture and sequestration (CCS), electric and hydrogen vehicles. In order to take account of the fact that China's sustainable energy development involves many dimen-sions, a six-dimensional indicator set has been established and applied with the aim of comprehensively evaluating different technology pathways in a uniform way. The ana-lysis reaches the following conclusions: (a) in the power sector, wind power, nuclear power and hydro power should be developed as much as possible, while R&D of solar power and coal power with CCS should be strengthened continuously for future deployment. (b) in the transporta-tion sector, there is no foreseeable silver bullet to replace oil on a large scale within the time frame of 20 to 30 years. To ease the severe energy security situation, expedient choices like coal derived fuels could be developed. However, its scale should be optimized in accordance to the trade-off of energy security benefits, production costs and environmental costs. Desirable alternative fuels (or technologies) like 2nd generation biofuels and electrical vehicles should be the subject of intensive R&D with the objective to be cost effective as early as possible.

Environmental and operator safety concerns are leading to the elimination of trichloroethylene and chlorofluorocarbon solvents in cleaning processes that remove rosin flux, organic and inorganic contamination, and particulates from electronic components. Present processes depend heavily on these solvents for manual spray cleaning of small components and subassemblies. Use of alternative solvent systems can lead to longer processing times and reduced quality. Automated spray cleaning can improve the quality of the cleaning process, thus enabling the productive use of environmentally conscious materials, while minimizing personnel exposure to hazardous materials. We describe the development of a prototype robotic system for cleaning electronic components in a spray cleaning workcell. An important feature of the prototype system is the capability to generate the robot paths and motions automatically from the CAD models of the part to be cleaned, and to embed cleaning process knowledge into the automatically programmed operations

Congress should enact legislation that supports residential property assessed clean energy (PACE) programs in the nation’s states and metropolitan areas. Such legislation should require the Federal Housing Finance Agency (FHFA) to allow Fannie Mae and Freddie Mac to purchase residential mortgages with PACE assessments while at the same time providing responsible underwriting standards and a set of benchmarks for residential PACE assessments in order to minimize financial risks to mortgage holders. Congressional support of residential PACE financing will improve energy efficiency, encourage job creation, and foster economic growth in the nation’s state and metropolitan areas.

The project has been designed to reduce energy consumption for air purification by 30% while having a payback period of maximum 3 years. The project has achieved very significant results which are far above the target. Particularly satisfying is the wide range of new components that are launched in late 2012. By implementing the newly developed system at 100% cleaning (LPC 13 ventilators and Dynamic multistep control) in relation to Best Practice (SKOV's original system with DA600 fans) in a concrete pigsty, a saving of 61% and a simple payback of 1.7 years is achieved. Similarly, it is found that the energy used for pump operation can be reduced by 37% with the new Dynamic sprinkling control. At 20% cleaning a potential saving of 15% per year and a payback period of between 0 and 5 years was found, which is dependent on the desired performance as the capacities in the bio-filter's upper capacity range between 26 thousand to 30 thousand m3 / h entails costs for an additional extraction unit in the new solution. Furthermore, the newly developed components proved highly suitable for standard installations without air cleaning where a savings potential is 53% and the payback period 1.5 years. Product-wise, the project formed the basis for the development of: 1. New energy-efficient ventilation units (LPC11, 12,13) that are suitable for air purification; 2. A new energy-saving control principle (Dynamic Multi-Step) which is particularly suitable for low-energy ventilators; 3. A new energy-saving flow measurement system for ventilating ducts (Dynamic air to the central exhaust); 4. An energy-saving pressure control in common ducts (pressure control as a function of outside temperature); 5. Proposal for a new energy-saving pump operation for sprinkling of biological filters (Dynamic sprinkling). (LN)

Rath, Bhakta B.

Recent price fluctuations have focused attention on the phenomenal increase of global energy consumption in recent years. We have almost reached a peak in global oil production. Total world consumption of oil will rise by nearly 60% between 1999 and 2020. In 1999 consumption was 86 million barrels of oil per day, which has reached a peak of production extracted from most known oil reserves. These projections, if accurate, will present an unprecedented crisis to the global economy and industry. As an example, in the United States, nearly 40% of energy usage is provided by petroleum, of which nearly a third is used in transportation. An aggressive search for alternate energy sources, both renewable and nonrenewable, is vital. This article will review national and international perspectives on the exploration of alternate energies with a focus on energy derivable from the ocean.

A Brief Review on Recent Trends in Alternative Sources of Energy

Alternative energy is any energy source that is an alternative to fossil fuel. These alternatives are intended to address concerns about such fossil fuels. Today, because of the variety of energy choices and differing goals of their advocates, defining some energy types as "alternative" is highly controversial. Most of the recent and existing alternative sources of energy are discussed below

The paper investigates the contributions of foreign direct investment (FDI) net inflows to clean energy use, carbon emissions, and economic growth. The paper employs cointegration tests to examine a long-run equilibrium relationship among the variables and fixed effects models to examine the magnitude of FDI contributions to the other variables. The paper analyzes panel data of 19 nations of the G20 from 1971 to 2009. The test results indicate that FDI has played an important role in economic growth for the G20 whereas it limits its impact on an increase in CO 2 emissions in the economies. The research finds no compelling evidence of FDI link with clean energy use. Given the results, the paper discusses FDI's potential role in achieving green growth goals. - Highlights: ► FDI inflows strongly lead to economic growth in the G20. ► FDI inflows lead to an increase in energy use in the G20. ► FDI inflows are in no relation to CO 2 emissions in the G20. ► FDI inflows are in no relation to clean energy use in the G20. ► Economic growth is in negative relation to CO 2 emissions in the G20

Geographic information systems (GIS) technology was applied to analyze federal energy demand across the contiguous US. Several federal energy clusters were previously identified, including Hampton Roads, Virginia, which was subsequently studied in detail. This study provides an analysis of three additional diverse federal energy clusters. The analysis shows that there are potential sites in various federal energy clusters that could be evaluated further for placement of an integral pressurized-water reactor (iPWR) to support meeting federal clean energy goals.

Enabling optimal energy options under the Clean Development Mechanism

Gilau, Asmerom M.; Van Buskirk, Robert; Small, Mitchell J.

This paper addresses the cost effectiveness of renewable energy technologies in achieving low abatement costs and promoting sustainable developments under the Clean Development Mechanism (CDM). According to the results of our optimal energy option's analysis, at project scale, compared with a diesel-only energy option, photovoltaic (PV)-diesel (PVDB), wind-diesel (WDB) and PV-wind-diesel (PVWDB) hybrids are very cost-effective energy options. Moreover, energy options with high levels of renewable energy, including 100% renewables, have the lowest net present cost and they are already cost effective without CDM. On the other hand, while the removal of about 87% carbon dioxide emissions could be achieved at negative cost, initial investment could increase by a factor of 40, which is one of the primary barriers hindering wider renewable energy applications in developing countries, among others. Thus, in order to increase developing countries' participation in the carbon market, CDM policy should shift from a purely market-oriented approach to investigating how to facilitate renewable energy projects through barrier removal. Thus, we recommend that further research should focus on how to efficiently remove renewable energy implementation barriers as a means to improve developing countries' participation in meaningful emission reduction while at the same time meeting the needs of sustainable economic development

Economics of alternative energy supply in New Zealand

Energy Technology Data Exchange (ETDEWEB)

Walker, B. V.

1977-10-15

Alternative means of supplying the main categories of energy demand in New Zealand are examined, using a common economic basis. In this context alternative means are defined to include those not presently in significant large-scale use in New Zealand but which have been demonstrated to be broadly technically feasible. Energy demand is conveniently divided into four categories each corresponding to a grade of energy required and each including all relevant demand in households, commerce, and industry. These categories are called low-grade heat, process heat, transport, and high-grade energy. The high-grade energy market is largely satisfied only by electricity and alternative means of supplying electricity are considered by other authors. The remaining categories are discussed. The comparison of alternatives includes a brief examination of how the comparative economics are affected by the economic criteria used and particularly the cash flow discount rate. The results obtained are of scoping accuracy only but some policy implications are suggested.

Electrical energy alternatives and their effect on the environment

The US has alternated its favored electrical energy sources several times over the past fifty years. It may soon change course again. Fifty years ago, the favored source was hydroelectric power. Electricity demand at the time was relatively small in comparison to today. Many rivers provided excellent, economical sites. In the 1950s, rapid growth in demand shifted interest to gas and oil because they were relatively clean, cheap, and easily transportable. A growing dependency on foreign oil led to the oil embargo and the rapid increase of prices in the 1970s. Use of oil was then discouraged by cost and federal regulation. Natural gas prices rose with oil prices, and federal regulations multiplied. Coal and uranium emerged as the favored fuels. However, nuclear power then came into disfavor in the late 1970s and throughout the 1980s. Emphasis on coal increased. The need for short construction schedules and reduced atmospheric emissions has since returned the emphasis to natural gas. Now pollution concerns are calling all fossil fuels into question. Hydroelectric sites are unavailable. Oil supplies are limited and foreign sourced. Coal is recognized as a major source of pollution. Natural gas is costly and limited. Renewable energy sources are incapable of meeting needs. And nuclear power safety and waste disposal issues still hinder its acceptance. So, where does the US go from here?

Recent price fluctuations at the gas pump have brought our attention to the phenomenal increase of global energy consumption in recent years. It is now evident that we have almost reached a peak in global oil production. Several projections indicate that total world consumption of oil will rise by nearly 60 per cent between 1999 and 2020. In 1999 consumption was equivalent to 86 million barrels of oil per day, which has reached a peak of production extracted from most known oil reserves. These projections, if accurate, will present an unprecedented crisis to the global economy and industry. As an example, in the US, nearly 40 per cent of energy usage is provided by petroleum, of which nearly a third is used in transportation. The US Department of Defense (DOD) is the single largest buyer of fuel, amounting to, on the average, 13 million gallons per day. Additionally, these fuels have to meet different requirements that prevent use of ethanol additives and biodiesel. An aggressive search for alternate energy sources, both renewable and nonrenewable, is vital. The presentation will review national and DOD perspectives on the exploration of alternate energy with a focus on energy derivable from the ocean. )

CAFE compliance by light trucks: economic impacts of clean diesel engine

Teotia, A.; Vyas, A.; Cuenca, R.; Stodolsky, F.

1999-01-01

With the popularity of light trucks increasing in the United States, their share of the US light vehicle market had doubled between 1980 and 1996, climbing from 20 to 40%. By 1996, annual energy consumption for light trucks had risen to 5.97 x 10 15 Btu [5.97 quadrillion Btu, or ''quad'', or 6.30 x 10 18 joule (J)], compared to 7.94 quad (8.38 x 10 18 J) for cars. In recent years (since 1995), the fuel economy of US-manufactured light trucks (almost 99% of which use gasoline engines) has been below the Corporate Average Fuel Economy (CAFE) standards. This paper analyzes a strategy to reduce the CAFE shortfalls by adopting the new, highly energy-efficient clean diesel engine. Research on such engines has been funded by the US Department of Energy, Office of Heavy Vehicle Technologies, under its Light Truck Clean Diesel Engine Program. A clean diesel engine market penetration trajectory is developed, representing an industry response to meet the CAFE standards. Whether the engine will be produced inside the country or imported remains uncertain, so two cases are defined. Values of exports/imports of clean diesel engines/trucks under these cases are estimated. The macroeconomic benefits are estimated by using a model of the US economy developed by Standard and Poor's Data Resources, Inc. On the basis of gains in the gross domestic product projected under the alternative cases, domestic production of the clean diesel engine is favored over importing it. (author)
