  6. America`s energy supply

    Energy Technology Data Exchange (ETDEWEB)

    Steinmetz, C.P.

    1998-04-01

    The gist of the paper is to demonstrate that the economical utilization of the country`s energy supply requires generating electric power wherever hydraulic or fuel energy is available, and collecting the power electrically, just as it is distributed electrically. In the first section a short review of the country`s energy supply in fuel and water power is given, and it is shown that the total potential hydraulic energy of the country is about equal to the total utilized fuel energy. In the second section it is shown that the modern synchronous station is necessary for large hydraulic powers, but the solution of the problem of the economic development of the far more numerous smaller water powers is the adoption of the induction generator. However, the simplicity of the induction generator station results from the relegation of all the functions of excitation, regulation, and control to the main synchronous station. The economic advantage of the induction generator station is that its simplicity permits elimination of most of the hydraulic development by using, instead of one large synchronous station, a number of induction generator stations and collecting their power electrically. The third section considers the characteristics of the induction generator and the induction-generator station, and its method of operation, and discusses the condition of ``dropping out of step of the induction generator`` and its avoidance. In the appendix the corresponding problem is pointed out with reference to fuel power, showing that many millions of kilowatts of potential power are wasted by burning fuel and thereby degrading its energy, that could be recovered by interposing simple steam turbine induction generators between the boiler and the steam heating systems, and collecting their power electrically.

  7. GDP and environment pressure: The role of energy in Latin America and the Caribbean

    International Nuclear Information System (INIS)

    This paper analyzes the relationship between economic growth and energy consumption for a sample of 21 Latin American and Caribbean countries during the 1970–2007 period. The investigation is made on the bases of the Energy Environmental Kuznets Curve (EEKC) hypothesis, using a panel data analysis. Energy consumption at aggregate level is used as an indicator of human environmental pressure and GDP per capita as an indicator of economic activity. Based in a cointegration approach, our results does not support the existence of a stable long run relationship between the series, rejecting the validity of such hypothesis for the selected sample over the 1970–2007 period. - Highlights: ► We analyze the relationship between energy consumption and per capita GDP. ► The main objective is to study the environmental pressure of energy consumption. ► We use the theoretical framework of EKC hypothesis. ► We found a U-shaped pattern instead of an inverted one. ► Socio-economic and institutional factors of the sample could explain our results.

  8. Biomass energy in Central America

    International Nuclear Information System (INIS)

    The objective of this paper is to introduce the concept of biomass to energy issues and opportunities in Central America. In this region, made up of seven countries (Belize, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua and Panama), the biomass sector has the potential to play a crucial role in alleviating the environmental and development predicaments faced by all economies of the region. This paper assesses the available biomass resources at the regional and country levels and gives an overview of the current utilization of biomass fuels. It also describes the overall context in which the biomass-to-energy initiatives are immersed. At the regional level, biomass energy consumption accounts for more than 50% of total energy consumption. In regard to the utilization of biomass for energy purposes, it is clear that Central America faces a critical juncture at two levels, both mainly in rural areas: in the productive sector and at the household level. The absence of sustainable development policies and practices has jeopardized the availability of biomass fuels, particularly wood. Firewood is an important source of energy for rural industries such as coffee processing, which is one of the largest productive activities in the region. This paper comments on some of the most successful technological innovations already in place in the region, for instance, the rapid development of co-generation projects by the sugar cane industry, especially in El Salvador and Guatemala, the substitution of coffee husks for firewood in coffee processing plants in Costa Rica and El Salvador and the sustainable use of pine forests for co-generation in Honduras. Only one out of every two inhabitants in Central America now has access to electricity from the public grid. Biomass fuels, mainly firewood but also, to a lesser extent, other crop residues such as corn stalks, are the main source of energy for cooking and heating by most of the population. (It is foreseen that by the end

  10. Atomic energy in Latin America

    International Nuclear Information System (INIS)

    Most countries in Latin America, including all those on the mainland, are Members of the Agency. Interest in the possibilities of nuclear energy has led to considerable activity, much of it in direct collaboration with the IAEA. Member States in the region are: Argentina, Bolivia, Brazil, Chile, Colombia, Costa Rica, Cuba, Dominican Republic, Ecuador, El Salvador, Guatemala, Haiti, Honduras, Jamaica, Mexico, Nicaragua, Panama, Paraguay, Peru, Uruguay, Venezuela. Of these, Argentina, Brazil, Colombia and Venezuela are operating, and Mexico and Uruguay are constructing, research reactors, while Chile and Peru are studying proposals. Argentina, Brazil, Mexico and Uruguay have all agreed to accept Agency safeguards for reactors. The possibility of future needs for nuclear power is under examination by several countries, in some cases being related to desalination of water. All atomic work in Latin America is devoted to peaceful uses, and note-worthy progress has been made with proposals for a treaty which would make the whole region a militarily de-nuclearized zone. It is proposed that when this comes into effect the Agency will be asked to apply the controls developed in its safeguards system, and to carry out the inspections necessary to establish that work in progress is solely for peaceful purposes

    1994-10-01

    Whilst recognising that the reduction of poverty levels in developing countries takes precedence to the improvement and protection of the environment, the author comments that any efforts geared to fostering socioeconomic development will indirectly address the environment issue. The aims of a broad strategy and a more specific energy strategy geared at fostering sustainable development in Latin America are discussed. It is suggested that development of hydropower should continue, that the share of natural gas in the regional energy balance be increased and that efforts be put into increasing energy efficiency and improving utilization technologies. Promotion of energy projects that generate employment, promotion of projects for the use of biomass as an energy source, and implementation of a series of joint ventures are ideas advocated. Possibilities of cooperation between the Latin American Energy Organization (OLADE) and the Dutch government are aired.

    2006-02-15

    This regional study is comprised of three case studies, which concentrate on Greater Buenos Aires, Caracas and Rio de Janeiro - Caju. Each case focuses on the analysis of specific aspects of urban poverty, energy availability and policies to improve living conditions from the energy point of view. Unlike other developing regions in the world, the problem of energy poverty in Latin America has been concentrated increasingly in the large cities and urban areas. This problem has deep systemic, economic, political, structural and cultural roots. Providing basic energy services to the urban poor is an issue that requires far more attention and expertise than it is receiving today, and therefore WEC has taken the initiative to address this issue, and the results of their study are presented in this report.

    Being considered an intermediate growth among projections of technological development expressive or of development restricted by ecological considerations, in the next 50 years, the demand of primary energy in the countries of the American continent arrived to value sufficiently high to allow to consent at levels of quality of life but next to those enjoyed at the moment in developed countries. There will be an expansion substantial of electric power demand that rots to require the installation, in countries of Latin America and Caribbean, of power plants with total capacity of the order of 400 GW until half-filled of century. The resource to the nuclear source was accentuated starting from the decade of 2020 and an enormous challenge for the governments of the region it will be the one of driving the construction of about 2.300 MW/year nuclear power plants between 2020 and 2050.

    The emerging U.S. bioenergy industry provides a secure and growing supply of transportation fuels, biopower, and bioproducts produced from a range of abundant, renewable biomass resources. Bioenergy can help ensure a secure, sustainable, and economically sound future by reducing U.S. dependence on foreign oil, developing domestic clean energy sources, and generating domestic green jobs. Bioenergy can also help address growing concerns about climate change by reducing greenhouse gas emissions to create a healthier environment for current and future generations.

  4. Energy environment and health

    International Nuclear Information System (INIS)

    During the colonial period and well into the 20th century, Cuba's economic development was based mainly on extensive agricultural production, with unsustainable use and exploitation of the land and severe deforestation. Consequently, by the middle of the century Cuba had a problematic economic structure based largely on traditional agricultural production, with limited industrial development mainly concentrated in the sugarcane agro-industry, and an environment affected by deforestation. The social situation was critical, with high levels of poverty and low levels of health services. The profound economic and social transformations achieved since 1959 have led to favourable changes in the living conditions of the population and to increased protection of the environment and conservation of natural resources. Among the concrete actions taken to protect the environment was the preparation and approval of the National Environmental Strategy, through which the country's main environmental problems and their significant negative effects on the health and living standards of the population were identified. Today, Cuba's main environmental problems are soil degradation, deterioration of sanitation and environmental conditions in human settlements, contamination of inland and marine waters, deforestation and loss of biological diversity. The environmental impact of the energy sector in Cuba is considerable. The widespread use of old technologies, the lack of waste treatment plants and the financial resources needed for the introduction of new technologies, technological malpractice and the lack of an environmental consciousness in the recent past are the main reasons for this negative impact. The following sections address the environmental legislation and policies currently in place and the environmental impacts of the different energy sources

  7. Energy security in South America and Southern Africa: synthesis report

    International Nuclear Information System (INIS)

    In developing countries, the ability to provide adequate and reliable energy supplies is a key to sustainable economic development. The aim of this report is to study the energy supply security in both Southern Africa and South America and how these regions can participate in the international effort to combat climate change. This report showed that South Africa's energy sector mostly relies on carbon intensive coal while Brazil is mainly supplied by hydroelectricity. It was found that in both countries energy needs will increase significantly due to rising demand both internally and at a regional scale. However it was also shown that both Southern Africa and South America have important hydro, solar and wind renewable resources which could enhance their electricity security while minimizing their environmental impacts. This study demonstrated that Southern Africa and South America can enhance their electricity security through the use of renewable energies but that technology and financing is needed to develop the sector.

    2004-12-01

    With NSF-CCLI funding, we have developed, taught, and evaluated a new lower-division science course for non-majors, entitled "Geography, Resources, and Environment of Hispanic America" (GRELA). This is an adaptation of a similar course, "Geology and Development of Modern Africa" developed by Barbara Tewksbury (Hamilton College), to attract African American students to science by highlighting cultural ties with their ancestral lands. We think that a similar approach focusing on Latin America may attract Hispanic undergraduates, at the same time that it increases awareness among non-Hispanic students about challenges facing our neighbors to the south. GRELA is an interdisciplinary exploration of how the physical and biological environment of Mexico, Central America, and South America have influenced the people who live there. The course consists of 20 lectures and requires the student to present a report partnering with correspondents in Latin American universities. GRELA begins with an overview of Latin American physical and cultural geography and geologic evolution followed by a series of modules that relate the natural resources and environment of Latin America to the history, economy, and culture of the region. This is followed by an exploration of pre-Columbian cultures. The use of metals by pre-Columbian, colonial, and modern cultures is presented next. We then discuss hydrocarbon resources, geothermal energy, and natural hazards of volcanoes and earthquakes. The last half of the course focuses on Earth System Science themes, including El Nino, glaciers, the Amazon river and rainforest, and coral reefs. The final presentation concerns population growth and water resources along the US-Mexico border. Grades are based on two midterms, one final, and a project which requires that groups of students communicate with scientists in Latin America to explore some aspect of geography, natural resources, or the environment of a Latin American region of common interest

    This research, which was conducted with crew members of an America's Cup team, had the following objectives: (a) to assess energy expenditure and intake during training; (b) to evaluate the sailors' diet, and (c) to identify any dietary flaws to determine the appropriate intake of nutrients, correct possible dietary mistakes, and improve their food habits. Energy expenditure was estimated on 15 sailors using direct measurements (oxygen consumption) and a 3-day activity questionnaire. Oxygen consumption was measured on sailors during both on-water America's Cup sailing training and dry-land fitness training. Composition of the diet was estimated using a 3-day food record. Average daily energy expenditure of the sailors ranged from 14.95 to 24.4 MJ, depending on body mass and boat role, with the highest values found in grinders and mastmen. Daily energy intake ranged from 15.7 to 23.3 MJ (from +6% to -18% of energy expenditure). The contributions of carbohydrate, protein, and fat to total energy intake were 43%, 18%, and 39% respectively, values that are not in accord with the recommended guidelines for athletes. Our results show the importance of assessing energy balance and food habits for America's Cup sailors performing different roles. The practical outcome of this study was that the sailors were given dietary advice and prescribed a Mediterranean diet, explained in specific nutrition lectures. PMID:17613739

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

  1. Nuclear energy and the environment

    International Nuclear Information System (INIS)

    The thesis of this paper is that the world will need more energy and not less in the coming decades but that this enormous energy consumption entails dangers to the environment not only locally but regionally and internationally through the emissions from the burning of fossil fuels which now provide 85% of the world's commercial energy supply. The solution to this problem is nuclear power. It does not contribute to global warming. 12 figs

    The current unsustainable practices worldwide in energy production and consumption have led to a plethora of environmental problems. Until recently environmental law largely overlooked the relevance of energy production and consumption; energy was seen to be of little significance to the advancement of sustainable development. This has changed since 2000 with the global concern attached to climate change, the publication by the United Nations of the World Energy Assessment and the detailed consideration given to this issue at the World Summit on Sustainable Development in Johannesburg in 2002. Australia has been seen to be lagging behind the other major industrialised nations of the world in addressing sustainable energy issues. Contents are: Overview of energy production and use in Australia; 2. Energy technologies and sustainable development; 3. Energy, international environmental law and sustainable development; 4. Evaluating Australian government initiatives relating to energy, climate change and the environment; 5. Sustainable energy in the Australian electricity and gas sectors; 6.

    Environmental health problems of children in Latin America and Ecuador are complex due to the close relationship that exists between social and environmental factors. Extended poverty and basic problems, such as the lack of drinking water and sanitation, are common. Infectious diseases are the greatest cause of morbidity and mortality among children. Development in industry and the introduction of chemical substances in agriculture add new risks including pesticide use, heavy metal exposure, and air pollution. Major problems can be divided into (a) lack of basic infrastructure, (b) poor living conditions, (c) specific environmental problems, and (d) child labor. Reproductive health disorders are frequent in developing countries like Ecuador. Issues related to children's health should consider new approaches, creative methodologies, and the search for independent predictors to separate environmental from social problems. Only with knowledge of the specific contribution of each factor, can it be possible to develop a strategy for prevention.

    The U.S. DOE Building America program has established a research agenda targeting market-relevant strategies to achieve 40% reductions in existing home energy use by 2030. Deep Energy Retrofits (DERs) are part of the strategy to meet and exceed this goal. DERs are projects that create new, valuable assets from existing residences, by bringing homes into alignment with the expectations of the 21st century. Ideally, high energy using, dated homes that are failing to provide adequate modern services to their owners and occupants (e.g., comfortable temperatures, acceptable humidity, clean, healthy), are transformed through comprehensive upgrades to the building envelope, services and miscellaneous loads into next generation high performance homes. These guidance documents provide information to aid in the broader market adoption of DERs. They are intended for inclusion in the online resource the Building America Solutions Center (BASC). This document is an assemblage of multiple entries in the BASC, each of which addresses a specific aspect of Deep Energy Retrofit best practices for projects targeting at least 50% energy reductions. The contents are based upon a review of actual DERs in the U.S., as well as a mixture of engineering judgment, published guidance from DOE research in technologies and DERs, simulations of cost-optimal DERs, Energy Star and Consortium for Energy Efficiency (CEE) product criteria, and energy codes.

  10. Energy situation in Latin America and nuclear power

    International Nuclear Information System (INIS)

    The stage of economic development and the standard of living of individuals in a given region strongly influence the link between economic growth and energy demand. Advanced economies with high living standards have a relatively high level of energy use per capita. (Fig 1). Some 1.6 billion people one-quarter of the world population have no access to electricity. Four out of five people without electricity live in rural areas of the developing world. Electricity generation in the world is expected to nearly double between 2006 and 2025, from around 14.500 billion KWh to 26.000 billion KWh. The strongest growth in net electricity consumption is projected for the emerging economies of the world, averaging 4.0 percent per year (1). Although the nations of Central and South America are on favourable economic growth paths, the region's growth rate remains well below potential. Energy consumption induced by economic growth shows an increasing tendency in Latin America characterized by rapidly growing primary energy demand. Both residential and industrial electricity consumption had an increasing tendency in Latin America. In the last 15 years the increase was 60% and 74%, respectively. (2) Twelve countries in the region: Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, El Salvador, Mexico, Paraguay, Peru, Uruguay and Venezuela, comprise 87% of the population and 93% of its installed electricity generating capacity. (2). (Fig 2). Latin America is a region rich in primary energy resources, where hydro-generation, especially in Brazil, has been dominating the power industry over the past decades. However, it is important to highlight the decreasing tendency of the share of hydroelectricity in total generation, which was reduced from 63% in 1990 to 55% in 2003,(2). At the same time, the most dynamically emerging primary energy resource is, at present, natural gas. These increasing tendency imply a growing reliance on non renewable fossil fuel utilization and a rising

    Full Text Available The increased availability of reliable and efficient energy services stimulates new development alternatives. This article discusses the potential for such integrated systems in the stationary and portable power market in response to the critical need for a cleaner energy technology. Anticipated patterns of future energy use and consequent environmental impacts (acid precipitation, ozone depletion and the greenhouse effect or global warming are comprehensively discussed in this paper. Throughout the theme several issues relating to renewable energies, environment and sustainable development are examined from both current and future perspectives. It is concluded that renewable environmentally friendly energy must be encouraged, promoted, implemented and demonstrated by full-scale plan especially for use in remote rural areas.

  12. Energy, pollution, environment and health

    International Nuclear Information System (INIS)

    Many of the major environmental problems of today, such as climate change, air pollution, acidification of lakes and forests, deforestation and desertification, share a common causal factor: energy - its production, transformation and final use. The burning of fossil fuels has already contributed to acidification of lakes and forests, and threatens to alter the world's climate. Traditional open fires cause indoor air pollution, thereby harming the health of women and children in the Third World. In many developing countries, the disappearing forest base is increasingly unable to supply enough wood for energy needs, leading to even greater pressure on forests, which in turn can lead to desertification. Nuclear reactor accidents may release large quantities of radioactive materials, and hydro dams may fail and inundate large areas of land. Indeed, every energy system has some impact on health and the environment, either affecting the same group of people who enjoy the benefits: the exposure of a small group to fumes from a poorly vented common cooking device; or a different group: acid rain in one country caused by the burning of fossil fuels in another, or harm to the health of future generations from today's radioactive nuclear waste. During the past two decades, these energy- environment impacts have become so serious that they may limit further growth of the world's energy economy. Consequently, these problems are now being examined more closely by decision makers throughout the world, as well as by the general public. In addition, it has become clear that energy cannot be viewed in isolation and that pollution, environment and health issues must be integrated into the development of national and international energy policies, so that the adverse impacts of energy can be reduced. To do this, the relationships among different energy systems and their impacts need to be defined clearly. To that end, UNEP has convened conferences on this topic and prepared several

  13. Energy balances for Europe and North America 1970-2000

    International Nuclear Information System (INIS)

    This publication is based on the ECE Energy Data Bank collected by the Senior Advisers to ECE Governments on Energy, supplemented by other official data available to the secretariat. The Energy Data Base contains energy balances from 1960 to 1985 for the market economy countries of western Europe and North America and from 1965 to 1985 for the centrally planned economy countries of eastern Europe. During the first session of the Senior Advisers to ECE Governments on Energy held in 1979, countries decided to circulate a questionnaire on Selected Energy Issues covering the years 1973, 1978, 1980, 1985, 1990 and 2000 (ECE/ENERGY/2, para. 29). While the methodology for establishing the balances has been mutually agreed, the assumptions underlying each country's forecast are not necessarily comparable. At their fifth session held from 23 to 27 September 1985, the Senior Advisers to ECE Governments on Energy agreed to issue a second questionnaire to collect revised projections for the years 1990 and 2000 (ECE/ENERGY/11, para. 50(b)). Information received served as benchmarks to construct a time series from 1970 to 1985. Commodities listed include solid fossil fuels, petroleum fuels, gaseous fuels both natural and derived, nuclear energy, hydro- and geothermal energy, electricity, steam and hot water, energy derived from non-conventional energy sources (solar, wind, wave, tidal, etc.)

    Expansion of the internal market and external, production on a large scale and more dynamic economic growth would be the consequences of a regional integration in South America. However, due to the specific characteristics of South America this process did not occur. Many attempts were made through the years with the creation of institutions that tried to promote the integration of different forms of South America. This article analyses the current economic conditions in which this initiative is to achieve an energy integration, which seems feasible given the provision expresses the presidents of South American countries before a possible rationing of energy. Through analysis of the results it may be concluded that there is a growing demand for energy in all countries, which should be resolved first in order not to cut the development of South America. The main economic aspects which affect the process of integrating energy are the commercial structures of energy, the energy complementarities, the degree of development of infrastructure for interconnection, the industrial structure and conformation electric business. However, an immediate solution would be to boost bilateral integration energy projects and construction of transmission lines that interconnect the regional stations for the supply of electric energy. Moreover, as the conditions are not improved political and economic and there is no compatible models between technical institutions and legal and administrative, will not be achieved significant progress in the process of regional energy integration of South America.

    The President's Solar America Initiative (SAI) was launched in January 2006 as part of the administration's Advanced Energy Initiative. The SAI is being led by the U.S. Department of Energy (DOE) Solar Energy Technologies Program (SETP), with NREL providing analytical and technical support. The SAI has a goal of installing 5-10 GW of photovoltaic (PV) systems in the United States by 2015 and 70-100 GW of PV systems in the United States by 2030. To make PV cost-competitive with other energy resources, this requires that the installed cost of PV fall from approximately $8/Wdc in 2005 to $3.3/Wdc in 2015 and $2.5/Wdc in 2030. This report presents estimates of the potential energy, economic, and environmental benefits that could result should the SAI PV installation goals be achieved.

    Full Text Available Producing energy to supply the demands of our societies is reaching a critical limit. To tackle this issue, there is a slow renaissance of fission reactors and the push to realise fusion reactors. The safe, reliable and optimal performance of fusion and fission plants is dependent on the choice of suitable materials used as components and fuels. As these materials are degraded by their exposure to high temperatures, irradiation and a corrosive environment, it is necessary to address the issue of long term degradation of materials under service exposure in advanced plants. A higher confidence in life-time assessments of these materials requires an understanding of the related physical phenomena on a range of scales from the atomic level of single defect energetics all the way up to macroscopic effects.

    The study presents a dataset intercomparison of reanalyses, data from other authors, and one regional climate model applied over South America with special focus on the hydrological cycle and the surface energy budget. The model simulated the 41 years from 1960 to 2000 by using quasi-observed boundary conditions derived from ECMWF re-analysis (ERA). The intercomparison focuses on one large catchment covering an area of major research interest within Colombia. The variables used are monthly mean surface air temperature, precipitation and river discharge. From the modelling perspective, the potential advantages of such comparative analyses are to provide information about model performance, enhance the understanding of hydrological behavior in a systematic dataset comparison framework, characterize consistencies and differences in datasets, and identify the requirements for catchment-scale hydrological models to reliably simulate future behavior.

    During the 2009 annual meeting of the Poultry Science Association, a symposium entitled "Global Views of New Agriculture: Food, Energy, and the Environment" was held that focused on several major issues affecting agriculture. Issues included future funding for basic agricultural research, sustainability, bioenergy, and their effects on global food markets. In many ways, a subtitle for the symposium could have been "Agriculture-Why What We Do Matters." It matters because of the fiscal and physical realities the planet will face in the coming decades relative to human population growth and the increasing demands to feed a hungry world. The challenges are daunting and the technologies to address them will require us to reevaluate the structure and policies we have established relative to agricultural research. In this case, change is all the more difficult because the traditional model of agricultural research has been so successful. One only needs to note the remarkable increases in productivity of the past half century of commodities such as corn and soybeans or feed efficiencies among broilers, laying hens, and turkeys to recognize the significant advancements that have been achieved. However, these historic gains have frequently required increased inputs, most notably fossil fuels. Food production in the future will likely be confronted with concerns involving energy, water, climate change, and the threat of agroterrorism. For example, we will need to develop crops that are more drought-resistant and more tolerant to a wider range of salinities as access to fresh water becomes more problematic. Animal agriculture will also need to adapt to diets composed of atypical feedstuffs. Whether future generations will inherit a world described by Paul Roberts in his books The End of Oil and The End of Food will be in part determined by the research model we adopt in the near term.

    2009-09-25

    This thesis analyzes the relationship between environmental regulation as well as energy market developments on the one hand, and economic performance on the other. Due to its economic effects environmental regulation is controversially disputed. The thesis shows, however, that the economic impacts of the recently adopted climate policy in Europe, namely of the implementation of the European Union Emission Trading Scheme, have been modest at most. Consistent with economic theory, the low stringency of this regulatory measure that is aimed at combating man-made climate change is identified as one important driver of this result. Moreover, results presented in this thesis also indicate the important role which the political economy plays for the design of environmental regulation in general. These mechanisms are shown to be a driver of the low stringency and, consequently, of the small economic effects during the first phase of the European Union Emission Trading Scheme. The thesis highlights the role of investment stimulation if the goal of environmental regulation is not only the protection of the environment, but also the compatibility with economic goals. This thesis also provides new insights into the role of energy market developments for the economy. In this respect, the relevance of the EU carbon market for the financial market performance of European electricity generators is shown. Besides, this thesis particularly demonstrates the paramount importance of oil market developments for the economy as a whole. It suggests that amongst all natural resources, oil is the most relevant one to the pricing of Eurozone energy stocks. It is also shown that besides oil prices, oil volatility plays an important role for stock market development. Finally, the thesis highlights the relevance of oil market developments to the overall economy, in showing that unemployment in Germany is strongly affected by oil price shocks. In this respect, it also opposes claims that the

    The influence of collective and multilocal environments on the energy transfer between the levels of a dimer is studied. The dynamics of energy transfer are investigated by considering coupling of collective environment with the levels of the dimer in the presence of both two individuals and mutually correlated multilocal environments. It is shown that every way of coupling we consider assists, though differently, the probability of transition between the levels of dimer. The probability of transition is strongly enhanced when the two local environments are mutually correlated. -- Highlights: • The dynamics of energy transfer between the levels of a dimer are studied. • Coupling of collective as well as individual environments are considered. • The environments are in spin star configurations. • The environment assists the energy transfer between the levels. • For correlated multilocal environments, the transition probability is almost 100%.

  9. Nuclear energy, radiation and environment

    International Nuclear Information System (INIS)

    Over the past few decades, energy has been the subject of much debate. Energy is the backbone of technology and economic development. Today, most machines run on electricity and they are needed to make anything and everything. Hence, our energy requirements have spiraled in the years following the industrial revolution. This rapid increase in use of energy has created problems of demand and supply in addition to the environmental consciousness which picked momentum in last decades of 20th century. The impending crisis the world over due to overuse of nonrenewable energy sources to reduce this gap shall soon lead to a situation for all concerned to take a prudent decision to tap other sources of energy, including relatively new renewable sources. Future economic growth crucially depends on the long-term availability of energy from sources that are affordable, accessible and environmentally friendly. The drive for more energy has had the happy consequences of spawning new technologies and improving earlier ones. Emphasis on renewable sources has resulted in viable harnessing of solar, wind and tidal energies. Even though these sources offer relatively clean energy, their potential to supply reliable energy in large scale in an economically viable way is limited. Nuclear energy offers a major source of commercial energy, which is economic, reliable and environmentally benign

  10. Technology, energy and the environment

    Science.gov (United States)

    Mitchell, Glenn Terry

    This dissertation consists of three distinct papers concerned with technology, energy and the environment. The first paper is an empirical analysis of production under uncertainty, using agricultural production data from the central United States. Unlike previous work, this analysis identifies the effect of actual realizations of weather as well as farmers' expectations about weather. The results indicate that both of these are significant factors explaining short run profits in agriculture. Expectations about weather, called climate, affect production choices, and actual weather affects realized output. These results provide better understanding of the effect of climate change in agriculture. The second paper examines how emissions taxes induce innovation that reduces pollution. A polluting firm chooses technical improvement to minimize cost over an infinite horizon, given an emission tax set by a planner. This leads to a solution path for technical change. Changes in the tax rate affect the path for innovation. Setting the tax at equal to the marginal damage (which is optimal in a static setting with no technical change) is not optimal in the presence of technical change. When abatement is also available as an alternative to technical change, changes in the tax can have mixed effects, due to substitution effects. The third paper extends the theoretical framework for exploring the diffusion of new technologies. Information about new technologies spreads through the economy by means of a network. The pattern of diffusion will depend on the structure of this network. Observed networks are the result of an evolutionary process. This paper identifies how these evolutionary outcomes compare with optimal solutions. The conditions guaranteeing convergence to an optimal outcome are quite stringent. It is useful to determine the set of initial population states that do converge to an optimal outcome. The distribution of costs and benefits among the agents within an

    Schimmelfing, Kara

    Energy related shortages and price volatilities can impact all levels of society. With coming fossil fuel depletion related to peak oil, it is expected these shortages and volatilities will increase in frequency, duration, and intensity. Resilience building is a strategy to minimize the effects of these events by modifying systems so they are less impacted and/or recover more quickly from disruptive events. Resilience building is being used, particularly at the municipal scale, to prepare for these coming energy related changes. These municipal efforts have only been in existence for five to ten years, and full implementation is still in progress. Little evaluation has been done of these municipal efforts to date, particularly in North America. Despite this, it is important to begin to assess the effectiveness of these efforts now. As a result, future efforts can be redirected to address weak areas and that lessons learned by vanguard communities can be applied in other communities attempting to build energy resilience in the future. This thesis involved the creation of a hybrid framework to evaluate municipal energy resilience building efforts. The framework drew primarily from planning process and factors identified as important to build resilience in social-ecological systems. It consisted of the following categories to group resilience building efforts: Economy, Resource Systems & Infrastructure, Public Awareness, Social Services, Transportation, Built Environment, and Natural Environment. Within these categories the following process steps should be observed: Context, Goals, Needs, Processes, and Outcomes. This framework was then tested through application to four case-study communities (Bloomington, IN, Hamilton, ON, Oakland, CA, Victoria, BC) currently pursuing energy resilience building efforts in North America. This qualitative research involved document analysis primarily of municipal documents related to energy planning efforts. Supplementary interviews

    Latin American countries are experiencing an increasing burden of tobacco-related diseases. Smoke free policies are cost-effective interventions to control both exposure of nonsmokers to the toxic chemicals in secondhand tobacco smoke and to reduce the prevalence of smoking and its consequent morbidity and mortality. The World Health Organization Framework Convention on Tobacco Control has created momentum in Latin America to implement meaningful tobacco control policies. As of August 2007, Uruguay, two provinces and three cities in Argentina, and one state in Venezuela, had passed, regulated, and enforced 100% smokefree legislation. The tobacco industry, working through local subsidiaries, has been the strongest obstacle in achieving this goal and has prevented progress elsewhere in the region. During the 1990s, transnational tobacco companies Philip Morris International and British American Tobacco developed voluntary initiatives (“Courtesy of Choice” and “Environmental Tobacco Smoke Consultancy” programs) to prevent effective smokefree policies. Another important barrier in the region has often been a weak and fragmented local civil society. Opportunities in the region that should be taken into account are a high public support for smokefree environments and increasing capacity building available from international collaboration on tobacco control. Policymakers and tobacco control advocates should prioritize the implementation of smokefree policies in Latin America to protect nonsmokers, reduce smoking prevalence with its economic and disease burden in the region.

    Full Text Available The purpose of the study was to examine the impact and the extent to which global Political Environment affects a company’s pricing decisions, a study based on Da-Wood Trading in the United States of America. Data for this study was collected through observation during a three month internship at the company, and questionnaires were later administered to respondents. Personal interview was also used to gather data from one respondent. The findings were then presented in form of tables and graphs. The data collected indicates that there are globalization factors that play a role in determining prices for services offered. Exposure to crime comes out as the most prominent global political facto. However, like tariffs and currency fluctuations are seen to not have a significant impact on pricing decisions. The factors that are considered and highlighted in this study therefore are seen to vary in degree of importance and in how they influence pricing decisions.

  18. Energy and sustainable development in Latin America and the Caribbean: Approaches for the power policy

    International Nuclear Information System (INIS)

    Energy and sustainable development in Latin America and the Caribbean is a joint project of the Latin American Organization of Energia (OLADE), the Economic Commission for Latin America and the Caribbean (Cepal) of the United Nations and the Deutsche Gesellschaft fur Technische Zusammennarbeit (GTZ). The intention of this project is the one to fortify the processes of formulation of power policies to harmonize economic growth, social fairness and protection of the environment in order to contribute to that the reforms that come undertaking the countries from the region prohang to the sustainable development. The made work it is come off that the sustainability of the power development raises a series of challenges to future. Concordant with the reactivation of the economic growth in the Nineties a low power productivity is still pronounced. To this they add one reduced to cover of satisfaction of the power necessities and the forest deterioration, jointly with the low quality of the power consumption and the impacts in the level of transmissions that will have the incorporation of polluting sources in the expansion of the regional power systems. On the other hand, the work shows a preoccupation with respect to the sustainability of the expansion of the power systems. At the present time the countries of Latin America and the Caribbean do not have a significant responsibility in the global environmental problems, since single they generate 5% of the world-wide CO2 transmissions whereas the developed countries contribute around 70%. Nevertheless, the new power developments based on the greater hydrocarbon consumption will be able to increase the contribution from the region to the deterioration of the atmosphere. At the same time, the expansion based on the hydroelectric generation also has some limitations although it contributes positively to the mitigation of the transmissions, which raises new challenges to the reform of the power sector

    Historically, cost effective, reliable, sustainable, and environmentally friendly, use of geothermal energy has been limited to areas where obvious surface features pointed to the presence of a shallow local heat source, such as hot springs and volcanoes. However, recent technological advances have dramatically expanded the range and size of viable resources, especially for applications such as modular power generation, home heating, and other applications that can use heat directly. These recent developments have greatly expanded opportunities for utilizing geothermal energy. Reflecting cu

    Can energy storage (ES) increase the share of renewable energy (RE) in total generation in Latin America and the Caribbean (LAC)? The rationale for using ES in combination with RE in the LAC region is that it can enable a larger scale deployment of cost-saving intermittent RE, with which the region is highly endowed, without threatening grid stability or the ability to meet electricity demand. To test this rationale, the paper considers three case studies that represent the key market types i...

  3. Electric energy and the environment

    International Nuclear Information System (INIS)

    An analysis was made of the emission of air pollutants by the Argentine public utilities, taking into account the historical evolution from 1970 to 1989. This has shown the impact which the substitution policies implemented in the electrical sector have had on the emission of pollutants and on the 'greenhouse effect'. On the one hand, these policies consisted of the substitution of conventional thermal energy by hydroelectric and nuclear energy and, on the other hand, substitution of fuel oil, diesel oil and coal by natural gas. Since the conventional thermal power stations require additional investments in order to avoid air pollution, the investment savings originated in this respect by the abovementioned substitution policies have also been calculated. Although the environmental impacts caused by hydroelectric, nuclear and natural gas production installations are also important and are located geographically in other areas, there is no doubt that the substitution policies carried out in the Argentine electrical sector signify both an ecological and an economic benefit.

    2013-04-01

    Waterspout outbreak occurrences are examined for the areas of the Aegean and Ionian Seas, Eastern Mediterranean, the Baltic Sea in Northern Europe and the Great Lakes of North America. Notable outbreaks included a series of 13 waterspouts on September 5, 2002, and 25 plus waterspouts on September 21, 2006 off the Cretan north coast in the Aegean Sea. Two outbreak days with 10 waterspouts each, occurred on August 11 and 13, 2006 over the Baltic Sea. During the fall of 2003 an outbreak produced about 66 waterspouts during a week over the Great Lakes of North America. A preliminary climatology of waterspout outbreak occurrences showed August as the most active month for the Baltic Sea and the Great Lakes and September for the Aegean and Ionian Seas; a feature primary related to the warmest sea surface temperatures during these months. Synoptic data indicated that a closed low (CLOSED) type pattern prevailed during waterspout outbreaks over the Baltic and the Aegean and Ionian Seas and a longwave (LW) type over the Great Lakes. Thermodynamic, wind and moisture data indicated a marginally unstable environment for most waterspout outbreaks. A steep thermal gradient between the water surface and lowest layers proved to be a primary factor for Great Lakes waterspout outbreak occurrences. For the Baltic Sea, the primary factors were balanced between the thermal contrast in the lowest layers and the total positive buoyancy. For the Aegean and Ionian Seas, positive buoyancy was the dominant factor. Selected waterspout outbreak case studies are investigated in order to present specific synoptic, thermodynamic features and predictability for the three areas. The Szilagyi waterspout nomogram, which is used as a forecasting tool, was applied together with the Szilagyi waterspout index (SWI) and found to be strongly correlated with outbreak occurrences for the three geographical areas.

  1. The energy-development-environment nexus

    International Nuclear Information System (INIS)

    Energy is the key factor in tackling two of the major problems now facing humanity: the environment and development. Adequate and appropriate energy supplies are essential to economic and social development, especially for Third World countries, but at the same time energy production and utilization are responsible for much of the damage being done to the environment. As everyone now knows, the combustion of fossil fuels is the main source of greenhouse gases and of the threat to the stability of world climate. Nuclear power, which once seemed an answer to the constantly increasing demand for energy, is now challenged by public opinion in many countries as a result of various nuclear accidents and the problems of processing and storing nuclear waste. So how do we extricate ourselves from the energy environment-development tangle? Clearly, advanced countries have an interest in transferring environment-friendly technologies to developing countries in order to reduce the pollution which puts the global as well as the local environment at risk. The North is, by and large, becoming aware of the choices involved in protecting the environment versus industrial growth and unlimited use of motor vehicles. For the South, these choices are a luxury they can ill afford, given the imperative of rapid development. The solution must be for greater international co-operation, with the North assisting the South (and the former Communist bloc) financially and through transfer of appropriate technologies at affordable cost. Reconciling the environment and development with respect to the energy cycle is a task of fundamental importance for the future. The prime responsibility for this task obviously lies with industries, but action is also required from governments, to enable them to play their part effectively. Advanced countries must demonstrate that development is fully compatible with protecting the environment. They can do so by using market forces, provided that the appropriate

    Since the mid 1970s, DOE has invested some $70 million in research and development at Lawrence Berkeley Laboratory (LBL) for development of advanced energy-efficient building technologies, software, and standards. That investment has helped spawn a $2.4-billion U.S. market for key products-energy-efficient lighting and advanced window coatings-and efficiency standards for residential equipment and computerized tools for more efficient building design. By 1993 DOE`s initial investment had reduced consumers` energy bills by an estimated $5 billion ($1.3 billion in 1993 alone). By 2015 we estimate that the products of that investment will save consumers $16 billion annually. LBL research partnerships address a host of other building technology issues as well-building technology issues whose economic benefits are less easy to quantify but whose overall worth is equally important. We analyze public policy issues such as the role of efficiency options as a mitigation strategy for global climate change. We develop planning and demand-management methodologies for electric and gas utilities. We identify technologies and analytical methods for improving human comfort and the quality of indoor air. We contribute to the information superhighway. We focus on the special problems and opportunities presented by energy use in the public sector. And we do all these things at the local, national, and international levels.

  8. Green energy. Biomass fuels and the environment

    International Nuclear Information System (INIS)

    The United Nations Environment Programme has been concerned with energy/environment issues since it was first set up after the United Nations Conference on the Human Environment held in Stockholm in 1972. In the late 1970s, UNEP compiled three comprehensive reports on the the environmental impacts of the production and use of fossil fuels, nuclear energy and renewable energy sources. In 1987 it was decided to update the volume on renewable energy since knowledge of biofuels and their effects on the environment had greatly improved. Among many innovations, Brazil's decision to embark on a major, and now successful, programme to produce ethanol from sugarcane as a substitute vehicle fuel is one of the most significant. At the same time, energy tree crops, agroforestry systems and the use of plantations for environmental improvement have become issues of key importance to sustainable development in developing countries. Biomass fuels, of course, have always been important in terms of the numbers of people who use them; the significant change during the 1980s was that the potential advantages of these fuels took on a new significance in the light of environmental degradation and related issues such as greenhouse warming. The biomass fuels began to be considered as attractive energy sources in their own right - not simply as 'last resort' fuels for developing countries with only limited energy options. While this development may solve some environmental problems, it certainly raises others - the improper utilization of biomass fuels in the past has been responsible for deforestation, desertification and the ill health of many millions of the women in developing countries who use biomass fuels in unventilated huts. These issues currently affect about half of the world population. The new UNEP study was intended to provide an up-to-date evaluation of the environmental issues raised by the use of biomass fuels, and hence to reduce or eliminate their adverse impacts while

    Full Text Available China’s current national policies promote high levels of economic growth, transforming China into a “world factory”, but at a high cost in terms of energy and the environment. At the same time, this growth and transformation also forms the backbone of China’s economy, underpinning social stability. China faces a dilemma to reconcile its economy, energy system and environmental security. Each aspect of this triad is discussed in this study to illuminate the challenges faced by China, and China’s dilemma in energy, economy and environment is analyzed from the perspective of its participation in current global supply chains. While China must import a significant proportion of its energy and a large proportion of primary materials, a large share of these imports are returned to the global market as industrial exports. China is bound by its own course of action and unable to radically change its position for the foreseeable future as the road to economic development and employment stability is through policies built on exports and shifting development models, presenting a tough socio-economic trade-off. China’s growth challenges are discussed as an example of challenges more broadly faced in the developing world. China’s success or failure in achieving a sustainable developmental pattern will inevitably have a significant influence on the global environment.

    Full Text Available The article describes the development and use of policy instruments and tools for energy cooperation promotion between Kazakhstan and the United States. The role of energy diplomacy in foreign policy strategy of the Republic of Kazakhstan is due to the progressive growth of the relationship between the economic interests of Kazakhstan and the United States. The main objectives of the energy policy of the Republic of Kazakhstan are: the internal energy market formation, energy supplies on a competitive basis and energy security provision, as well as the improvement of the environmental sustainability of the energy. Modern American transnational enterprises have at their disposal significant financial resources, technological and managerial capacity. They are able to develop oil and gas fields effectively in the Republic of Kazakhstan with the least financial costs and minimal environmental damage.

    The Building America program conducts the system research required to reduce risks associated with the design and construction of homes that use an average of 30% to 90% less total energy for all residential energy uses than the Building America Research Benchmark, including research on homes that will use zero net energy on annual basis. To measure the program's progress, annual research milestones have been established for five major climate regions in the United States. The system research activities required to reach each milestone take from 3 to 5 years to complete and include research in individual test houses, studies in pre-production prototypes, and research studies with lead builders that provide early examples that the specified energy savings level can be successfully achieved on a production basis. This report summarizes research results for the 30% energy savings level and demonstrates that lead builders can successfully provide 30% homes in Cold Climates on a cost-neutral basis.

    The objective of this article is, on one hand, to evaluate the dependency of the United States (US) as far as its oil imports, and by the other, the regional consequences that could mean the declination of the production and of the Mexican exports. Mexico could put into injunction the diversification looked for by US and have other undesirable consequences, such as higher prices and bilateral and including international tensions. In addition, the fall of the oil exports will damage the public finances of Mexico, reason why the reform of its energy sector and the necessity of moderating the dependency of the government from the oil income by means of a fiscal reform that can not be postponed, in spite of the strong prevailing political resistance. [Spanish] El objetivo de este articulo es, por un lado, evaluar la dependencia de Estados Unidos (EU) en cuanto a sus importaciones de petroleo, y por el otro, las consecuencias regionales que podria significar la declinacion de la produccion y de las exportaciones mexicanas.

    We explore excitonic energy transfer dynamics in a molecular dimer system coupled to both structured and unstructured oscillator environments. By extending the reaction coordinate master equation technique developed by Iles-Smith et al. [Phys. Rev. A 90, 032114 (2014)], we go beyond the commonly...... correlations generated between the system and its environment when the Born-Markov approximations no longer hold. Finally, we apply the reaction coordinate formalism to the case of a structured environment comprising of both underdamped (i.e., sharply peaked) and overdamped (broad) components simultaneously...... of motion over a wide range of parameters. Furthermore, we show that the Zusman equations, which may be obtained in a semiclassical limit of the reaction coordinate model, are often incapable of describing the correct dynamical behaviour.

  19. The importance of advancing technology to America's energy goals

    International Nuclear Information System (INIS)

    A wide range of energy technologies appears to be needed for the United States to meet its energy goals. A method is developed that relates the uncertainty of technological progress in eleven technology areas to the achievement of CO2 mitigation and reduced oil dependence. We conclude that to be confident of meeting both energy goals, each technology area must have a much better than 50/50 probability of success, that carbon capture and sequestration, biomass, battery electric or fuel cell vehicles, advanced fossil liquids, and energy efficiency technologies for buildings appear to be almost essential, and that the success of each one of the 11 technologies is important. These inferences are robust to moderate variations in assumptions.

    The geothermal energy is explained together with the global environment. The global environment problem comprises ozonospheric destruction, acid rain and global warming. The important elements of measures against the global warming are rise in prediction accuracy (rise in accuracy of prediction model for which the reflection on the cloud, rainfall and evaporation, percentage of the ocean, and biosystem are taken into consideration) and technological development for the measures (high efficiency utilization of energy, reduction in CO2 production, CO2 removal, storage and recycling technology). A prediction example of the worldwide energy in 2050 indicates that the nuclear power, fossil fuel and geothermal energy occupy 50, 20 and 8%, respectively. Though poor in economical performance, the geothermal power generation will be competitive, if assumption is made of a future rise in fossil fuel cost. It is more practical than the photovoltaic power generation and wind power generation. Its CO2 emission per kWH is smaller than that of the hydraulic power generation and nuclear power generation. In the geothermal power generation, H2S largely influences the atmospheric environment. As measures against the H2S, stretford and other different processes are put in practical use. For the water quality environment, what is important is measures against the As. 24 refs., 25 figs., 2 tabs.

    Main purpose of this research is to investigate about how to use energy tax system to reconcile environmental protection and economic growth, and promote sustainable development with the emphasis of double dividend hypothesis. As preliminary work to attain this target, in this limited study I will investigate the specific conditions under which double dividend hypothesis can be valid, and set up the model for optimal energy taxation. The model will be used in the simulation process in the next project. As the beginning part in this research, I provide a brief review about energy taxation policies in Sweden, Netherlands, and the United States. From this review it can be asserted that European countries are more aggressive in the application of environmental taxes like energy taxes for a cleaner environment than the United States. In next part I examined the rationale for optimal environmental taxation in the first-best and the second-best setting. Then I investigated energy taxation how it can provoke various distortions in markets and be connected to the marginal environmental damages and environmental taxation. In the next chapter, I examined the environmentally motivated taxation in the point of optimal commodity taxation view. Also I identified the impacts of environmental taxation in various circumstances intensively to find out when the environment tax can yield double dividend after taking into account of even tax-interaction effects. Then it can be found that even though in general the environmental tax exacerbates the distortion in the market rather than alleviates, it can also improve the welfare and the employment under several specific circumstances which are classified as various inefficiencies in the existing tax system.

    Increased energy security and reduced carbon emissions pose significant challenges for science and technology. However, they also create substantial opportunities for innovative research and development. In this review paper, we highlight some of the key opportunities and mention public policies that are needed to enable the efforts and to maximize the probability of their success. Climate is among the uttermost nonlinear behaviors found around us. As recent studies showed the possible effect of cosmic rays on the Earth's climate, we investigate how complex interactions between the planet and its environment can be responsible for climate anomalies.

    Full Text Available As a reflection of the ecological pressures associated with rapid modernization and globalization, the environment has become an enduring theme of public debate and protest in Latin America. Over the past decade, scholars have made increasing connections between such debate and a range of questions related to citizenship. Meanwhile, a discourse of ‘environmental citizenship’ has a growing prevalence in policy across the region. While these developments echo similar political and academic trends in the Global North, the Latin American context demands a unique set of theoretical and methodological approaches to studying the intersection of ecology and citizenship, sensitive to the specific historical, cultural, and ecological character of the region. We outline a research agenda spanning questions of land, identity and citizenship; environmental justice and de-colonization; social subjectivity and the state; urban natures and citizens; and the materiality/subjectivity of nature. This array of approaches points to a more acute conceptualization of citizenship, both in terms of its understanding of politics and its treatment of ecology; it also offers a point of view that recognizes citizens and natures as dynamic realities, which mutually condition each other in a sphere of ongoing contest.   Resumen: Medio ambiente y ciudadanía en América Latina: un nuevo paradigma para la teoría y práctica Como reflexión de los impactos ecológicos asociados con la modernización rápida y la globalización, el medio ambiente se ha transformado en un tema de debate y protesta constante en Latinoamérica.

    This paper applies the competing theories of High Reliability Organizations (HRO and Normal Accidents Theory (NAT, two competing views of risk management in highly-complex and tightly-coupled systems, in analyzing the 1998 Ice Storm and the 2003 Blackout to examine vulnerabilities in North America’s critical energy infrastructure (CEI. Inferences are then made by highlighting the similarities and differences in the two cases, which are then used to draw lessons for public managers regarding the protection of CEIs.

     

    As CEIs are highly-complex and tightly-coupled systems, failures stemming from complex and uncertain risks are inevitable. There is an increasingly low tolerance for failure in energy infrastructure because society’s critical infrastructures have become increasingly interdependent. Public managers must regulate CEIs in order to ensure an emphasis is placed on safety and security while also finding ways to reduce unnecessary complexities. It is through the adoption of such measures that public managers will aid in minimizing the cascading effects of inevitable failures.

     

  10. Meta-Analysis of Income and Price Elasticities Energy Demand: Some Public Policy Implications for Latin America

    Directory of Open Access Journals (Sweden)

    Luis Miguel Galindo

    2015-08-01

    Full Text Available The aim of this paper is to analyze the variation in empirical estimates of the income and price elasticities of energy demand. The evidence presented, through a meta-analysis, allows identification of the weighted average of the income and price elasticities, shows that the estimates are very heterogeneous, that there is publication bias, and that factors such as region, energy sector, among others, affect its volatility. The evidence also indicates that income elasticity in Latin America is greater than in the OECD countries, and that the price elasticity of energy demand is lower in Latin America than in the OECD countries. Therefore, continued economic growth in Latin America will be accompanied by a growth in energy demand. Moreover, the establishment of a tax in Latin America, under the current elasticities, is less effective and will be insufficient to control the increase in energy consumption.

The Building America Program (BAP) is part of the Department of Energy (DOE), Energy Efficiency and Renewable Energy, Building Technologies Program (BTP). The long term goal of the BAP is to develop cost effective, production ready systems in five major climate zones that will result in zero energy homes (ZEH) that produce as much energy as they use on an annual basis by 2020. CARB is led by Steven Winter Associates, Inc. with Davis Energy Group, Inc. (DEG), MaGrann Associates, and Johnson Research, LLC as team members. In partnership with our numerous builders and industry partners, work was performed in three primary areas - advanced systems research, prototype home development, and technical support for communities of high performance homes. Our advanced systems research work focuses on developing a better understanding of the installed performance of advanced technology systems when integrated in a whole-house scenario. Technology systems researched included: - High-R Wall Assemblies - Non-Ducted Air-Source Heat Pumps - Low-Load HVAC Systems - Solar Thermal Water Heating - Ventilation Systems - Cold-Climate Ground and Air Source Heat Pumps - Hot/Dry Climate Air-to-Water Heat Pump - Condensing Boilers - Evaporative condensers - Water Heating CARB continued to support several prototype home projects in the design and specification phase. These projects are located in all five program climate regions and most are targeting greater than 50% source energy savings over the Building America Benchmark home. CARB provided technical support and developed builder project case studies to be included in near-term Joule Milestone reports for the following community scale projects: - SBER Overlook at

    Genomes of fungi relevant to energy and environment are in focus of the Fungal Genomic Program at the US Department of Energy Joint Genome Institute (JGI). One of its projects, the Genomics Encyclopedia of Fungi, targets fungi related to plant health (symbionts, pathogens, and biocontrol agents) and biorefinery processes (cellulose degradation, sugar fermentation, industrial hosts) by means of genome sequencing and analysis. New chapters of the Encyclopedia can be opened with user proposals to the JGI Community Sequencing Program (CSP). Another JGI project, the 1000 fungal genomes, explores fungal diversity on genome level at scale and is open for users to nominate new species for sequencing. Over 200 fungal genomes have been sequenced by JGI to date and released through MycoCosm (www.jgi.doe.gov/fungi), a fungal web-portal, which integrates sequence and functional data with genome analysis tools for user community. Sequence analysis supported by functional genomics leads to developing parts list for complex systems ranging from ecosystems of biofuel crops to biorefineries. Recent examples of such parts suggested by comparative genomics and functional analysis in these areas are presented here.

    Full Text Available In Colombia the regulatory process regarding the energy efficiency of end-use prod-ucts is emerging with the draft technical regulation product labeling RETIQ, which includes in Annex E, the test methods for determining the efficiency of motors alternat-ing current induction. The goal of this paper is to compare the energy efficiency of induction motors between the countries of Latin America and the countries of the major economies of the globe, considering four aspects: the current state of classification standards and test procedures of induction motors efficiency, multilateral agreements of mutual recognition, the infrastructure to conduct tests of the standard and support programs to improve the efficiency of electric motor-driven systems. The study reveals that Latin America is a considerable delay in the implementation of classification standards and methods for testing the efficiency of electric motors, most widely used in the world: IEC 60034-30:2008, IEC 60034-2-1: 2007 IEEE 112:2004 and EPAct'92, with respect to the countries of the European Union, United States, China, Australia, and other developed countries, in which these standards have been adopted. Furthermore, the region is evident in the absence of programs focused on improving the energy efficiency of electric motors and a limited number of accredited laboratories to evaluate their efficiency, which leads to most Latin American countries to establish agreements mutual recognition for this purpose.

    Full Text Available In Colombia the regulatory process regarding the energy efficiency of end-use products is emerging with the draft technical regulation product labeling RETIQ, which includes in Annex E, the test methods for determining the efficiency of motors alternating current induction. The goal of this paper is to compare the energy efficiency of induction motors between the countries of Latin America and the countries of the major economies of the globe, considering four aspects: the current state of classification standards and test procedures of induction motors efficiency, multilateral agreements of mutual recognition, the infrastructure to conduct tests of the standard and support programs to improve the efficiency of electric motor-driven systems. The study reveals that Latin America is a considerable delay in the implementation of classification standards and methods for testing the efficiency of electric motors, most widely used in the world: IEC 60034-30:2008, IEC 60034-2-1: 2007 IEEE 112:2004 and EPAct'92, with respect to the countries of the European Union, United States, China, Australia, and other developed countries, in which these standards have been adopted.

    This study examines the causal relationships among energy consumption, economic growth and carbon dioxide emissions in twenty countries from Latin America and the Caribbean region. The methodology includes the use of Phillips and Perron (PP) tests, a cointegration model with vector error correction modeling (VECM) and vector autoregression (VAR) with Granger causality. The study concludes that of the twenty countries analyzed, only in four of them will it be possible to implement energy conservation polices without affecting their economic growth, four others are not able to consider an energy conservation policy with economic growth, and the other twelve should focus on their economic growth before adopting any conservation policies. Energy efficiency was found in this region, especially in the countries which have both cointegration and short-term equilibrium. - Highlights: > Only four countries could implement energy conservation polices without affecting economic growth. > Twelve nations should focus on their economic growth before designing any energy conservation policies. > Energy efficiency was found in the countries which have both cointegration and short-term equilibrium.

    Full Text Available Application of new and renewable sources of energy available in Sudan is now a major issue in the future energy strategic planning for the alternative to the fossil conventional energy to provide part of the local energy demand. Like many of the African leaders in renewable energy utilisation, Sudan has a well-defined commitment to continue research, development, and implementation of new technologies. Sustainable low-carbon energy scenarios for the new century emphasise the untapped potential of renewable resources are needed. Rural areas of Sudan can benefit from this transition. The increased availability of reliable and efficient energy services stimulates new development alternatives. It is concluded that renewable environmentally friendly energy must be encouraged, promoted, implemented, and demonstrated by full-scale plant especially for use in remote rural areas.

  13. Energy, environment, and sustainable development in the new century

    International Nuclear Information System (INIS)

    The new century's ultimate global challenge will be for the world community to sustain its growth while preserving environment in the presence of ever increasing world population, that is, balancing economy, environment, and population problems. The sheer magnitude of population growth, together with people's innate aspirations for improved life, will put enormous demands on energy production. Deployment of new, energy-intensive technologies will further increase the pressure. The increased energy production and consumption in turn will inevitably impact on our global environment, as exemplified by such issues as global climate change. Environmental issues associated with energy production and use are affecting society's preferences for different types of energy. Thus, energy and environment will remain two poles of a central global issue in this century. The challenge is then how to produce energy in a way that is friendly to environment. The combination of nuclear power and various renewable energy sources may offer a key component to meeting the challenge. This paper presents a big picture of globally sustainable development in the new century. The role of energy and environment is brought to the fore in this context. In particular, it addresses the importance of nuclear power and renewable energy, as this combination of options will absolutely minimize the emission of greenhouse gases that have steadily and alarmingly degraded our atmospheric environment.

    Making major gains in energy efficiency is one of the most economical and effective ways our nation can wean itself off its dependence on foreign oil and reduce its emissions of greenhouse gases. Transportation and buildings, which account for two thirds of American energy usage, consume far more than they need to, but even though there are many affordable energy efficient technologies that can save consumers money, market imperfections inhibit their adoption. To overcome the barriers, the federal government must adopt policies that will transform the investments into economic and societal benefit. And the federal government must invest in research and development programs that target energy efficiency. Energy efficiency is one of America's great hidden energy reserves. We should begin tapping it now. Whether you want the United States to achieve greater energy security by weaning itself off foreign oil, sustain strong economic growth in the face of worldwide competition or reduce global warming by decreasing carbon emissions, energy efficiency is where you need to start. Thirty-five years ago the U.S. adopted national strategies, implemented policies and developed technologies that significantly improved energy efficiency. More than three decades have passed since then, and science and technology have progressed considerably, but U.S. energy policy has not. It is time to revisit the issue. In this report we examine the scientific and technological opportunities and policy actions that can make the United States more energy efficient, increase its security and reduce its impact on global warming. We believe the findings and recommendations will help Congress and the next administration to realize these goals. Our focus is on the transportation and buildings sectors of the economy. The opportunities are huge and the costs are small.

  17. Latin America, an important new player in the great global energy game. The possibilities for an energy dialogue

    International Nuclear Information System (INIS)

    The first part of this paper deals with the latin america. Latin American energy has become a major strategic and geopolitical issue. During the last three years events in Ecuador, Bolivia and Venezuela have shown that these countries also count in the development of the world gas and oil markets. The prospects of growth in the global demand for energy during the next twenty years make one realize the shortfall between world demand and availability, in the same way that the recurrence of geopolitical crises in the regions of the world oil producers, like the Middle East, could have a destabilizing effect on international economic and political balance. Latin America will thus have a key role to play, provided that its social and political crises do not become geopolitical crises of a much more serious nature. The second part presents the possibilities of the energy dialogue. Four essential factors determine today situation in the world market: the rapid growth in the demand for energy resources in Asian countries; the increasing gap between the quantities produced and those consumed in the industrialized countries; the capacity of refining facilities and transport is already insufficient, and additional oil production possibilities are limited; and finally, the lack of openness in the world market in black gold. Efforts aimed at bringing together energy strategies and systems are a key part of the cooperation between the European Union and Russia. A similar dialogue has begun with the principal emerging powers of the Asian-Pacific Region. Our cooperation, including that within the framework of Russia presidency of the G8, will essentially be aimed at putting in place a common system of development of the key aspects of our energy policy. We are ready to act as intermediary between all the parties concerned. (authors)

  18. Energy, environment and development in China

    International Nuclear Information System (INIS)

    Since the socialist revolution in 1949, China has undergone periods of strong growth followed by years of political turmoil and economic setback. However, for the period 1953-1988 as a whole, the gross domestic product (GDP) grew at an average rate of 6.9% p.a., while energy consumption showed a growth rate of 8.5%. Two features of the economy are important in order to understand the development and current structure of energy consumption: Manufacturing industry, in particular the energy intensive sectors, represent an exceptionally large share of GDP; regional and local self-reliance has been the major priority in Chinese economic policy. Hence, the economy is largely based on small units which do not enjoy the full benefits of economies of scale, nor have they the financial power or technical skills required to use modern technologies. These factors have contributed to the exceptionally high intensity (energy consumption per unit of GDP) in China. Though there are major flaws in comparing energy intensities between countries, it is generally believed that the aggregated energy intensity of China is three times the level of industrialized countries, and twice as high as in many other developing countries. China has achieved impressive results in energy improvements during the 1980s, albeit from a level of high energy intensity. Energy efficiency improved on average 4% p.a. from 1980 to 1988. The major part of the improvement (50-60%) was the results of changes to industrial structures, while technological improvements and improved management in industry contributed 1/3. Though important improvements in energy efficiency are expected, projections of energy consumption in this report indicate annual growth in energy consumption of 3.5% for the next 35 years. This will imply more than a threefold increase in CO2 emissions to 2025 (from 2 billions tons of CO2 in 1990 to 6.8 billion tons in 2025). 40 refs., 20 figs., 13 tabs

  3. Induced innovation, energy prices, and the environment

    Science.gov (United States)

    Popp, David Clifford

    The process of developing new technologies is a central question for economic theory as well as for public policy in many areas. For example, the development of cleaner, more efficient energy technologies will play an important role in reducing the threat of global warming. To study how technology evolves over time, this dissertation uses patent data on energy innovations from 1970 to 1991 to examine the impact of energy prices on energy-efficient innovations. Before this can be done, however, information on supply-side factors which influence innovation is also needed. In the case of innovation, supply-side factors are the usefulness of the existing base of scientific knowledge. Patent citations are used for this purpose. Subsequent citations to patents granted each year since 1970 are used to show that the returns to research and development (R&D) fall over time for most of the technologies studied. These estimates are then combined with data on demand-side factors, such as energy prices, to estimate a model of induced innovation in energy technologies. Both energy prices and the supply of knowledge are found to have strongly significant positive effects on innovation. Next, the Yale Technology Concordance (YTC), which maps patents to the industries in which they are used, is employed to construct a stock of energy-related knowledge for 14 energy intensive industries. The effect of changes in this stock on energy consumption in these industries is estimated. On average, the present value of energy savings resulting from a new patent is eight million dollars, with the maximum savings coming about five years after the initial patent application. Finally, the results of each regression are combined to simulate the impact of a ten percent energy tax. Initially, simple factor substitution due to the price change has the largest effect. However, because of the cumulative nature of R&D, induced innovation has a much larger effect than factor substitution in the long run

    Latin America has a wealth of renewable energy resources, although the utilization of these resources has historically been carried out in the region by large hydroelectric energy plants. Nevertheless, according to the present report, there is an immense potential for wider use of new sources of renewable energy, including Small-Scale Hydroelectric (SSH), wind, solar and geothermal. Considering only the renewable sources used for power generation in the countries studied, they are observed to account for between 2.5 and 5% of the current installed capacity of these countries. Brazil and Peru use roughly 5%, Argentina and Colombia 4% and Mexico and Chile 2.5% of current capacity. Among the alternative sources used, biomass is observed to be predominant, corresponding to 50% of the installed capacity of those countries, collectively, followed by SSH (37%) and wind energy (13%). The installed capacity of photovoltaic energy (PV) continues to be insignificant. In this work, large hydroelectric plants are not included as renewable sources, only CHP is included. Among the countries studied, Brazil is currently responsible for more than 70% of the installed capacity of the renewable sources used for power generation, followed by Mexico (9%) and Argentina (7%). Colombia and Central American countries represent 5% of current installed capacity, each, and the remaining countries are responsible for 2%, with the exception of Venezuela. The high contribution of biomass as an alternative source in Brazil and Argentina explains its predominance in this area. With respect to total hydroelectric potential, Mexico has already exploited a large part portion of its economically viable resources, as much as 87.4%, much higher than the average for the region. While Brazil stands out for the large participation of hydroelectric energy, 58.4% of the economically exploitable capacity still remains. Nevertheless, those resources are concentrated in the northern region of the country and

To measure the program's progress, annual research milestones have been established for five major climate regions in the United States. The system research activities required to reach each milestone take from 3 to 5 years to complete and include research in individual test houses, studies in pre-production prototypes, and research studies with lead builders that provide early examples that the specified energy savings level can be successfully achieved on a production basis. This report summarizes research results for the 30% energy savings level and demonstrates that lead builders can successfully provide 30% homes in the Marine Climate Region on a cost neutral basis.

  11. Energy, environment and development in Mexico

    International Nuclear Information System (INIS)

    Mexico is a country at the crossroads. It has huge potentials in energy, in natural resources and in human resources. It is currently experiencing one of the most serious crises in its history - economic, ecological, political - and it is making efforts to overcome the problems behind these crises, which may affect us all because of Mexico's importance as energy producer and energy consumer. Mexico is one of the developing countries which has participated actively in finding solutions to the worlds environmental problems not least the problem of climatic changes as a result of increasing energy consumption. Mexico is seeing the consequences at local and national level, and is taking steps to change course. At the same time, it has also expressed interest in participating in international initiatives and cooperation to solve these problem. But Mexico finds itself in a situation not unlike that of many East European countries after the fall of the communist regimes. The old system is tumbling, the will to change is present, but there is a lack of resources. 123 refs., 45 tabs

  12. A worldwide perspective on energy, environment and sustainable development

    International Nuclear Information System (INIS)

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

    The State Energy Advisory Board (STEAB) presents this 10th annual report following the one-year anniversary of the September 11, 2001 terrorist attacks on the World Trade Center and the Pentagon. This event has had profound impacts on all segments of American society, not the least of which is this country’s energy sector. Long before September 11, a number of energy issues grabbed the nation’s attention, including opening the Arctic National Wildlife Refuge to oil and natural gas exploration, the power crisis in California, nationwide natural gas and gasoline price increases, and the administration’s May 2001 National Energy Policy. However, the events of September 11 refocused attention on the prominent role energy plays in the country’s homeland security. For the most part, the energy aspects of homeland security have focused on the physical security of critical energy emergency planning and energy infrastructure, such as power plants, refineries, and power and fuel transmission systems. While STEAB recognizes the importance of protecting our existing energy infrastructure, this should not be the sole focus of homeland security as it relates to energy.

    Urban heat islands (UHIs) occur when urban and suburban areas experience elevated temperatures relative to their rural surroundings because of differences in vegetation cover, buildings and other development, and infrastructure. Most cities in the United States are warming at twice the rate of the outlying rural areas and the planet as a whole. This difference in temperature is proportional to the size of the city and can be in excess of 2-5°C during the daytime and as much as 10°C at night. UHIs can exacerbate the warming during heat waves and play a role in additional heat-related mortality, an increase in tropospheric ozone, and economic losses that total in the billions of dollars from excess energy consumption. Many cities are experimenting with strategies to reduce urban warming. A number of mitigation strategies involve manipulating the surface energy budget to either reduce the amount of solar radiation absorbed at the surface or offset absorbed energy through latent cooling. Options include using building materials with different properties of reflectivity and emissivity, increasing the reflectivity of parking lots, covering roofs with vegetation, and increasing the amount of vegetation overall through tree planting or increasing green space. The goal of the Islands in the Sun project is to understand the formation and behavior of urban heat islands and to mitigate their effects through sensible city engineering and design practices. Methods include analysis of global remotely sensed datasets, the development of a reduced-complexity urban model, and evaluation of measurements made in the Twin Cities Metropolitan Area (TCMA). The TCMA is a 7,700 square kilometer urban and suburban region located in east central Minnesota that includes the two cities of Minneapolis and Saint Paul. Mitigation of the UHI in northern latitude cities, such as the TCMA, is a challenge because (1) residents in more northerly cities are more likely to suffer heat-related illness

    Physical inactivity poses a significant challenge to physical and mental health. Environmental approaches to tackle physical inactivity have identified natural environments as potentially important public health resources. Despite this, little is known about characteristics of the activity involved when individuals visit different types of natural environment. Using Natural England's Monitor of Engagement with the Natural Environment Survey, we examined 71,603 English respondents' recreational visits to natural environments in the past week. Specifically, we examined the intensity of the activities they undertook on the visits (METs), the duration of their visit, and the associated total energy expenditure (MET minutes). Visits to countryside and urban greenspace environments were associated with more intense activities than visits to coastal environments. However, visits to coastal environments were associated with the most energy expenditure overall due to their relatively long duration. Results differed by the urbanity or rurality of the respondent's residence and also how far respondents travelled to their destination. Knowledge of what types of natural environment afford the highest volumes and intensities of physical activity could inform landscape architecture and exercise prescriptions. Isolating activity-supporting characteristics of natural environments that can be translated into urban design is important in providing physical activity opportunities for those less able to access expansive environments.

    2009-01-01

    With rapid urbanization and heavy industria-lization as well as the rapid increase of cars in China, the effect of energy consumption on urban air environment is increasingly becoming serious, and has become a hot topic for both scholars and decision-makers. This paper explores the effect mechanism and regulation of urban energy consumption on the air environment, and summarizes the framework of the stress effect relationship and the evolutionary process. In accordance with the effect relationship of the internal factors between the two, analytic approaches studying the stress effect of urban energy consumption on air environment are proposed, including the analysis of air environment effects caused by urban energy consumption structure change, and the analysis of air environment effects caused by urban energy economic efficiency change, as well as a decomposition analysis of air pollutant emission caused by urban energy consumption. Applying the above-mentioned approaches into a case study on Beijing City, this paper analyzes the effect relationship among urban energy consumption structure improvement, energy economic efficiency increase and air quality change since the period when Beijing City officially proposed to bid for the 2008 Olympic Games in 1998. In addition, it further analyzes the effect and contribution of urban industrial activity level, industrial economic structure, industrial energy intensity, and industrial energy structure as well as emission coefficients on the change in industrial SO2 emission, which can provide valuable information to the government for making comPrehensive environmental policies, with the use of the logarithmic mean Divisia index (LMDI) method. It is shown that under the precondition that the industrial economy maintain a continuous and rapid increase, improvements in energy intensity and a decline in emission coefficients are the main means for reducing Beijing's industrial SO2 emissions.

  9. Energy conservation and the environment: conflict or complement

    1978-09-01

    The policy discussion following the Oil Embargo was clouded with fears of a return to a primitive existence based on drastically reduced energy inputs to society, or, on the other hand, an abandoning of environmental goals, allegedly a major barrier to development of new energy supplies. Often the energy use associated with environmental improvements was cited as a reason for expanding energy supplies, as if to say that a conflict existed between a clean environment and reductions in energy use. Or it was argued that a relaxation of environmental goals would lower the direct costs of harvesting and using energy and thereby alleviate the need for energy conservation. It has also been argued that the geopolitics of energy alone will force us to substitute riskier or ''dirtier'' energy sources for relatively clean oil and gas. Indeed, there is no question that the relationship among energy, the environment, and economic well-being is complicated. This essay sorts out many of the confusing aspects in order to show how goals relating to the efficient use of energy are aligned both with traditional economic goals and with modern environmental goals. To do this the author analyzes in depth the role of energy in the economy and, using examples, traces the origins of many of the misconceptions about that role--misconceptions that have inhibited a profound discussion of energy-related goals.

    Three side-by-side lab houses were built, instrumented and monitored in an effort to determine through field testing and analysis the relative contributions of select technologies toward reducing energy use in new manufactured homes.The lab houses in Russellville, Alabama compared the performance of three homes built to varying levels of thermal integrity and HVAC equipment: a baseline HUD-code home equipped with an electric furnace and a split system air conditioner; an ENERGY STAR manufactured home with an enhanced thermal envelope and traditional split system heat pump; and a house designed to qualify for Zero Energy Ready Home designation with a ductless mini-split heat pump with transfer fan distribution system in place of the traditional duct system for distribution. Experiments were conducted in the lab houses to evaluate impact on energy and comfort of interior door position, window blind position and transfer fan operation. The report describes results of tracer gas and co-heating tests and presents calculation of the heat pump coefficient of performance for both the traditional heat pump and the ductless mini-split. A series of calibrated energy models was developed based on measured data and run in three locations in the Southeast to compare annual energy usage of the three homes.

    This document describes lessons learned from designing, building, and monitoring five affordable, energy-efficient test houses in a single development in the Tennessee Valley Authority (TVA) service area. This work was done through a collaboration of Habitat for Humanity Loudon County, the US Department of Energy (DOE), TVA, and Oak Ridge National Laboratory (ORNL).The houses were designed by a team led by ORNL and were constructed by Habitat's volunteers in Lenoir City, Tennessee. ZEH5, a two-story house and the last of the five test houses to be built, provided an excellent model for conducting research on affordable high-performance houses. The impressively low energy bills for this house have generated considerable interest from builders and homeowners around the country who wanted a similar home design that could be adapted to different climates. Because a design developed without the project constraints of ZEH5 would have more appeal for the mass market, plans for two houses were developed from ZEH5: a one-story design (ZEH6) and a two-story design (ZEH7). This report focuses on ZEH6, identical to ZEH5 except that the geothermal heat pump is replaced with a SEER 16 air source unit (like that used in ZEH4). The report also contains plans for the ZEH6 house. ZEH5 and ZEH6 both use 50% less energy than the DOE Building America protocol for energyefficient buildings. ZEH5 is a 4 bedroom, 2.5 bath, 2632 ft2 house with a home energy rating system (HERS) index of 43, which qualifies it for federal energy-efficiency incentives (a HERS rating of 0 is a zero-energy house, and a conventional new house would have a HERS rating of 100). This report is intended to help builders and homeowners build similar high-performance houses. Detailed specifications for the envelope and the equipment used in ZEH5 are compared with the Building America Benchmark building, and detailed drawings, specifications, and lessons learned in the construction and analysis of data gleaned

    As the book shows, energy relationships in the American continent are defined by the world's biggest energy consumer, the USA, paralleled by an increasing resources-related nationalism among the energy producers of the southern hemisphere of the continent. The strategic character of energy in all its different forms (petroleum and natural gas, coal, electricity, bioethanol) is reflected both in the development of the total hemispheral relationships and in various attempts to design regional integration processes. The subject is getting increasingly explosive due to problems with oil production in the Arctic region and off the US coast; in addition, there are first cooperation projects between state-owned Latin American companies and Chinese or Russian oil companies that are viewed with serious misgivings by the USA. This book presents infrastructural projects and cooperation projects in the context of national energy policies and takes a look at the potentials for conflict resulting from divergent conceptions and interests of the key actors.

    Latin America has a wealth of renewable energy resources, although the utilization of these resources has historically been carried out in the region by large hydroelectric energy plants. Nevertheless, according to the present report, there is an immense potential for wider use of new sources of renewable energy, including Small-Scale Hydroelectric (SSH), wind, solar and geothermal. Considering only the renewable sources used for power generation in the countries studied, they are observed to account for between 2.5 and 5% of the current installed capacity of these countries. Brazil and Peru use roughly 5%, Argentina and Colombia 4% and Mexico and Chile 2.5% of current capacity. Among the alternative sources used, biomass is observed to be predominant, corresponding to 50% of the installed capacity of those countries, collectively, followed by SSH (37%) and wind energy (13%). The installed capacity of photovoltaic energy (PV) continues to be insignificant. In this work, large hydroelectric plants are not included as renewable sources, only CHP is included. Among the countries studied, Brazil is currently responsible for more than 70% of the installed capacity of the renewable sources used for power generation, followed by Mexico (9%) and Argentina (7%). Colombia and Central American countries represent 5% of current installed capacity, each, and the remaining countries are responsible for 2%, with the exception of Venezuela. The high contribution of biomass as an alternative source in Brazil and Argentina explains its predominance in this area. With respect to total hydroelectric potential, Mexico has already exploited a large part portion of its economically viable resources, as much as 87.4%, much higher than the average for the region. While Brazil stands out for the large participation of hydroelectric energy, 58.4% of the economically exploitable capacity still remains. Nevertheless, those resources are concentrated in the northern region of the country and

  18. Shale Gas and Tight Oil: A Panacea for the Energy Woes of America?

    Hughes, J. D.

    2012-12-01

    Shale gas has been heralded as a "game changer" in the struggle to meet America's demand for energy. The "Pickens Plan" of Texas oil and gas pioneer T.Boone Pickens suggests that gas can replace coal for much of U.S. electricity generation, and oil for, at least, truck transportation1. Industry lobby groups such as ANGA declare "that the dream of clean, abundant, home grown energy is now reality"2. In Canada, politicians in British Columbia are racing to export the virtual bounty of shale gas via LNG to Asia (despite the fact that Canadian gas production is down 16 percent from its 2001 peak). And the EIA has forecast that the U.S. will become a net exporter of gas by 20213. Similarly, recent reports from Citigroup and Harvard suggest that an oil glut is on the horizon thanks in part to the application of fracking technology to formerly inaccessible low permeability tight oil plays. The fundamentals of well costs and declines belie this optimism. Shale gas is expensive gas. In the early days it was declared that "continuous plays" like shale gas were "manufacturing operations", and that geology didn't matter. One could drill a well anywhere, it was suggested, and expect consistent production. Unfortunately, Mother Nature always has the last word, and inevitably the vast expanses of purported potential shale gas resources contracted to "core" areas, where geological conditions were optimal. The cost to produce shale gas ranges from 4.00 per thousand cubic feet (mcf) to 10.00, depending on the play. Natural gas production is a story about declines which now amount to 32% per year in the U.S. So 22 billion cubic feet per day of production now has to be replaced each year to keep overall production flat. At current prices of 2.50/mcf, industry is short about 50 billion per year in cash flow to make this happen4. As a result I expect falling production and rising prices in the near to medium term. Similarly, tight oil plays in North Dakota and Texas have been heralded

    Full Text Available Solar Energy has been acknowledged as a free and infinite source of energy. In Built Environment (BE, solar energy has been used since pre-historic time. Many improvements and technologies .have been developed with respect to their potential. As solar supplies free energy, the issues with regard to their development in the BE will be examined. The solar energy is used in building either in Passive Solar Design (PSD or Active Solar Design (ASD. Rapid development in BE has caused global warming effect where the heating and cooling of the building contribute to half the total energy consumption of the nation and the construction industry leading to CO2 emission level at 300 million tonnes. It is found that solar energy produces different energy performances which result from different building technique that affected the environment in various ways. Whether or not the energy performances depend on the materials used, the equipment installed in the building or the energy sources supplied to the building , the improvement and development of solar energy still continues and grows.

    Sustainability on economical growth, energy supply and environment are major issues for the 21. century. Within this context, one of the promising concepts is the possibility of nuclear-produced hydrogen. In this study, the effect of nuclear-produced hydrogen on the environment is discussed, based on the output of the computer code 'Grape', which simulates the effects of the energy, environment and economy in 21. century. Five cases are assumed in this study. The first case is 'Business as usual by Internal Combustion Engine (ICE)', the second 'CO2 limited to 550 ppm by ICE', the third 'CO2 limited to 550 ppm by Hybrid Car', the fourth 'CO2 limited to 550 ppm by Fuel Cell Vehicle (FCV) with Hydrogen produced by conventional Steam Methane Reforming (SMR)' and the fifth 'CO2 limited to 550 ppm by FCV with Nuclear Produced-Hydrogen'. The energy used for transportation is at present about 25% of the total energy consumption in the world and is expected to be the same in the future, if there is no improvement of energy efficiency for transportation. On this point, the hybrid car shows the much better efficiency, about 2 times better than traditional internal combustion engines. Fuel Cell powered Vehicles are expected to be a key to resolving the combined issue of the environment and energy in this century. The nuclear-produced hydrogen is a better solution than conventional hydrogen production method using steam methane reforming. (author)

  2. The Fossil Fueled Metropolis: Los Angeles and the Emergence of Oil-Based Energy in North America, 1865--1930

    Science.gov (United States)

    Cooke, Jason Arthur

    Beginning with coal in the nineteenth century, the mass production and intensive consumption of fossil fuel energy fundamentally changed patterns of urban and industrial development in North America. Focusing on the metropolitan development of Los Angeles, this dissertation examines how the emergence of oil-based capitalism in the first three decades of the twentieth century was sustained and made increasingly resilient through the production of urban and industrial space. In a region where coal was scarce, the development of oil-based energy was predicated on long-term investments into conversion technologies, storage systems and distribution networks that facilitated the efficient and economical flow of liquefied fossil fuel. In this dissertation, I argue that the historical and geographical significance of the Southern California petroleum industry is derived from how its distinctive market expansion in the first three decades of the twentieth century helped establish the dominance of oil-based energy as the primary fuel for transportation in capitalist society. In North America, the origins of oil-based capitalism can be traced to the turn of the twentieth century when California was the largest oil-producing economy in the United States and Los Angeles was the fastest growing metropolitan region. This dissertation traces how Los Angeles became the first city in North America where oil became a formative element of urban and industrial development: not only as fuel for transportation, but also in the infrastructures, landscapes and networks that sustain a critical dependence on oil-based energy. With a distinctive metropolitan geography, decentralized and automobile-dependent, Los Angeles became the first oil-based city in North America and thus provides an ideal case study for examining the regional dynamics of energy transition, establishment and dependence. Interwoven with the production of urban and industrial space, oil remains the primary fuel that

  3. Young people and environment, technology, nuclear energy in France

    International Nuclear Information System (INIS)

    Young people have a particular attitude on the questions about environment and energy, and also about technology. Several inquiries show that young people are more aware of environmental questions than their elders. Their anxiety is bigger against pollution than the average of French people and it seems that they are more attentive to dangers for the planet: it is the sign of a broader opening on the world. Young people are ready to adhere to a group or association for environment and have sympathy for ecologists; they have hostility against nuclear energy. Age and education level have to be specified to complicate the question. This contribution gives some elements about the opinion of young people between 15-25 years old on environment, technology and nuclear energy in France. (N.C.)

    International Nuclear Information System (INIS)

    In the situation that world's population, especially in developing countries, is rapidly growing, humankind is facing to global problems that they cannot steadily live unless they find individual places to live, obtain foods, and peacefully get energy necessary for living for centuries. For this purpose, humankind has to think what behavior they should take in the finite environment, talk, agree and execute. Though energy has been long respected as a symbol for improving living, demanded and used, they have come to limit the use making the global environment more serious. If there is sufficient energy not loading cost to the environment. If nuclear energy regarded as such one sustain the resource for long and has market competitiveness. What situation of realization of compensating new energy is now in the case the use of nuclear energy is restricted by the society fearing radioactivity. If there are promising ones for the future. One concerning with the study of energy cannot go without knowing these. The statistical materials compiled here are thought to be useful for that purpose, and are collected mainly from ones viewing future prediction based on past practices. Studies on the prediction is so important to have future measures that these data bases are expected to be improved for better accuracy. (author)

    1972-01-01

    The relationship between the consumption of energy by technological cultures and the second law of thermodynamics is discussed. The analysis is based on a description of the operation of a mechanical device which consumes energy. It is concluded that the flow of energy in manifold spontaneous conditions, which play a vital role in the operation of any technological process, remove most of the energy flow path from the control of the operator. It is stated that the increased efficiency of a process can benefit the environment only as much as this efficiency enables the total energy input to be reduced for a given level of production and increasing efficiency cannot meet the problems of an increased rate of energy utilization.

    Energy is known as one of the essential ingredients for economic development and security of energy supply is crucial in ensuring continuous economic development of a country. Malaysia's proven domestic oil reserves are estimated to last for another 25 years, while that of gas for another 39 years as of 2011. Despite the depleting indigenous energy resources, the primary energy demand has continued to grow robustly, at an annual rate of 6.3 percent per year from 1990 to 2010, while the primary energy import has grown 7.2% per year and the primary energy export has grown at a slower rate of 1.9% per year. This worrying trend is further compounded by the faster rate of primary oil import averaging 10.5% per year while the primary energy export has shrink at a rate of 1.4% per year. This paper has identified two main concerns namely overdependence on fossil fuel and increasing energy import dependency in creating a precarious position towards energy self-sufficiency. The study will analyse the energy security of the country and explore possible options and challenges in enhancing the energy supply security toward sustainable environment.

  16. Paradise recovered: energy production and waste management in island environments

    International Nuclear Information System (INIS)

    In this study, we investigate the conclusions of a previous study by the authors regarding the competitiveness of waste-to-energy (WTE) technologies with data from Puerto Rico. Puerto Rico's situation matches many of the conditions laid out in the earlier study and the island is currently seeking to modernize its energy production and waste management options. Examining production and environmental costs, we find that modern pollution control technology, high-energy production costs, and limited availability of suitable landfill sites render WTE facilities an economically and environmentally attractive option for Puerto Rico. Similar results likely hold in other island environments

  17. Mechanisms linking energy balance and reproduction: impact of prenatal environment.

    2016-01-01

    The burgeoning field of metabolic reproduction regulation has been gaining momentum due to highly frequent discoveries of new neuroendocrine factors regulating both energy balance and reproduction. Universally throughout the animal kingdom, energy deficits inhibit the reproductive axis, which demonstrates that reproduction is acutely sensitive to fuel availability. Entrainment of reproductive efforts with energy availability is especially critical for females because they expend large amounts of energy on gestation and lactation. Research has identified an assortment of both central and peripheral factors involved in the metabolic regulation of reproduction. From an evolutionary perspective, these mechanisms likely evolved to optimize reproductive fitness in an environment with an unpredictable food supply and regular bouts of famine. To be effective, however, the mechanisms responsible for the metabolic regulation of reproduction must also retain developmental plasticity to allow organisms to adapt their reproductive strategies to their particular niche. In particular, the prenatal environment has emerged as a critical developmental window for programming the mechanisms responsible for the metabolic control of reproduction. This review will discuss the current knowledge about hormonal and molecular mechanisms that entrain reproduction with prevailing energy availability. In addition, it will provide an evolutionary, human life-history framework to assist in the interpretation of findings on gestational programming of the female reproductive function, with a focus on pubertal timing as an example. Future research should aim to shed light on mechanisms underlying the prenatal modulation of the adaptation to an environment with unstable resources in a way that optimizes reproductive fitness.

    In this study, the energy generation of a set of photovoltaic panels is compared with the energy load of a building in order to analyse its autonomy in the sahelian environment when taking into account, the orientation, the insulation and the energy transfer optimisation of its windows. The Type 56 TRNSYS multizone building model is utilized for the energy load simulation and the Type 94 model of the same code enables the coupling of photovoltaic (PV) panels with the building. Without insulation, the PV energy generation represents 73.52 and 111.79% of the building electric energy load, respectively for poly-crystalline and mono-crystalline panels. For the same PV characteristics and when we insulate the roof and the floor, the energy generation increases to represent successively 121.09 and 184.13%. In the meantime, for building without insulation and with insulate the roof, the floor and 2 cm insulated walls, the energy consumption ratios decrease respectively from 201.13 to 105.20 kWh/m2/year. The investigations finally show that it is even possible to generate excess energy (positive energy building) and reduce the number and incident surface area of the PV panels if we conjugate the previous model with building passive architectural design mode (orientation, solar protection ...).

    Many rapidly developing regions have begun to draw the attention of the world. Meanwhile, the energy and environmental issues associated with rapid economic growth have aroused widespread critical concern. Therefore, studying energy, economic, and environmental systems is of great importance. This study establishes a system dynamic model that covers multiple aspects of those systems, such as energy, economy, population, water pollution, air pollution, solid waste, and technology. The model designed here attempts to determine the impacts of socioeconomic development on the energy and environment of Tongzhou District in three scenarios: under current, planning, and sustainable conditions. The results reveal that energy shortages and water pollutions are very serious and are the key issues constraining future social and economic development. Solid waste emissions increase with population growth. The prediction results provide valuable insights into social advancement. PMID:24683332

  4. Environment-adjusted regional energy efficiency in Taiwan

    International Nuclear Information System (INIS)

    This study applies the four-stage DEA procedure to calculate the energy efficiency of 23 regions in Taiwan from 1998 to 2007. After controlling for the effects of external environments, only Taipei City, Chiayi City, and Kaohsiung City are energy efficient. Note that Kaohsiung City reaches the efficiency frontier due to the adjustment via partial environmental factors such as higher education attainment and transport vehicles. We also find a worsening trend for Taiwan's energy efficiency. Not only is there a gap of energy efficiency between Taiwan's metropolitan areas and the other regions, but the gap has also widened in recent years. Those inefficient counties should be given priority and the savings potential. Except for road density, the evidence indicates that each environmental factor has partial incremental effects on input slacks. As more cars and motorcycles are unfavorable externalities affecting partial energy efficiency, the central government should help local governments retire inefficient old motor vehicles, encourage energy-saving vehicle models, and provide convenient mass transportation systems. Besides, people with higher education cause industrial energy inefficient in Taiwan. The conscious of effective energy saving is necessary to schools, communities, and employee accordingly.

  5. Competitive energy markets. The effective route to improving the environment

    International Nuclear Information System (INIS)

    Market forces, operating in an increasingly competitive energy market, are a preferred route to achieving environmental and energy efficiency benefits, than those which can be achieved through a managed approach adopted by many governments. It is shown, through examples, how electricity is a catalyst for change at several levels in business, the community and the general economy. Experience in the United Kingdom indicates that free market forces and inter-energy competition not only help improve the regional and therefore national economy, but they offer a very effective way of introducing improvements in energy efficiency and the environment. Governments should establish the framework for competition and regulation but not attempt to manage an industry, which is invariably done more effectively by those who run them. (author)

  7. Nuclear neutrino energy spectra in high temperature astrophysical environments

    CERN Document Server

    Misch, G Wendell

    2016-01-01

    Astrophysical environments that reach temperatures greater than $\\sim$ 100 keV can have significant neutrino energy loss via both plasma processes and nuclear weak interactions. We find that nuclear processes likely produce the highest-energy neutrinos. Among the important weak nuclear interactions are both charged current channels (electron capture/emission and positron capture/emission) and neutral current channels (de-excitation of nuclei via neutrino pair emission). We show that in order to make a realistic prediction of the nuclear neutrino spectrum, one must take nuclear structure into account; in some cases, the most important transitions may involve excited states, possibly in both parent and daughter nuclei. We find that the standard technique of producing a neutrino energy spectrum by using a single transition with a Q-value and matrix element chosen to fit published neutrino production rates and energy losses will not accurately capture important spectral features.

  8. Proposal for an energy - environment strategy in Romania

  9. The Swedish Dilemma: Nuclear Energy v. the Environment

    International Nuclear Information System (INIS)

    A phaseout of nuclear power in Sweden is supposed to be accomplished by year 2010. This study is an economic analysis of the questions that are parts of the Swedish nuclear dilemma. Even though the economic questions are in focus, the important environmental, health and safety questions are also treated. The basic argument is that Sweden should choose an energy system that allows its citizens to maximize their consumption in a long-term perspective. Consumption is here given a meaning that includes elements outside the market, such as environmental, health and safety aspects valued in a reasonable way. Considerations must also be given to international aspects like global environment, a free and open system of trade and the value of a stable set of rules and proprietary rights. The study compares the economic pros and cons of different energy systems within this general frame. A detailed model of the Swedish energy and power sectors was developed for the study, called the Swedish Energy and Environment Policy (SEEP) model. The SEEP model is built on modern economic theory and includes energy and environmental factors in a uniform way. 51 refs, 36 tabs, 6 figs

    In the UK, there has been an increasing interest in the commercial aspects of the impact of wind energy on transmission and distribution networks. In a competitive electricity supply environment, mechanisms for pricing network services are considered to be the main vehicle for evaluating that impact. This article reviews the major pricing strategies based on embedded costs, short and long run marginal costing theory as well as time-of-use pricing, and comments on the influence of each particular strategy on the calculated value of wind energy. Also, prospective tools for evaluating savings in capital and operating network costs due to wind generation, are identified. (author)

    ?Ducts in conditioned space (DCS) represent a high priority measure for moving the next generation of new homes to the Zero Net Energy performance level. Various strategies exist for incorporating ducts within the conditioned thermal envelope. To support this activity, in 2013 the Pacific Gas & Electric Company initiated a project with Davis Energy Group (lead for the Building America team, Alliance for Residential Building Innovation) to solicit builder involvement in California to participate in field demonstrations of various DCS strategies. Builders were given incentives and design support in exchange for providing site access for construction observation, diagnostic testing, and builder survey feedback. Information from the project was designed to feed into California's 2016 Title 24 process, but also to serve as an initial mechanism to engage builders in more high performance construction strategies. This Building America project complemented information collected in the California project with BEopt simulations of DCS performance in hot/dry climate regions.

  17. Energy technologies and the environment: Environmental information handbook

    Energy Technology Data Exchange (ETDEWEB)

    1988-10-01

    This revision of Energy Technologies and the Environment reflects the changes in energy supply and demand, focus of environmental concern, and emphasis of energy research and development that have occurred since publication of the earlier edition in 1980. The increase in availability of oil and natural gas, at least for the near term, is responsible in part for a reduced emphasis on development of replacement fuels and technologies. Trends in energy development also have been influenced by an increased reliance on private industry initiatives, and a correspondingly reduced government involvement, in demonstrating more developed technologies. Environmental concerns related to acid rain and waste management continue to increase the demand for development of innovative energy systems. The basic criteria for including a technology in this report are that (1) the technology is a major current or potential future energy supply and (2) significant changes in employing or understanding the technology have occurred since publication of the 1980 edition. Coal is seen to be a continuing major source of energy supply, and thus chapters pertaining to the principal coal technologies have been revised from the 1980 edition (those on coal mining and preparation, conventional coal-fired power plants, fluidized-bed combustion, coal gasification, and coal liquefaction) or added as necessary to include emerging technologies (those on oil shale, combined-cycle power plants, coal-liquid mixtures, and fuel cells).

  18. Wind energy. Views on the environment: clean and green

    1999-12-01

    As the United States grapples with the issue of global climate change resulting from fossil fuel combustion, and as the U.S. Congress and individual state legislatures consider restructuring the electric utility industry, lawmakers should keep in mind the environmental preferability of renewable energy sources such as wind and the long, continuing record of public support for them. This is particularly important in view of restructuring, which will have the effect of shifting decisions about the type and quantity of new power plants to be built from utility executives to the general public. Preliminary information suggests that ''green,'' or environmentally-friendly, power sources could win a significant market share. In addition to creating new demand for clean energy sources, this development is likely to create a committed, educated political constituency for clean energy that has not existed in the past. In such an altered environment for the selection of new generation, public attitudes on the desirability of various power sources will become much more important than they have in the past. The purpose of this paper is to briefly summarize public opinion surveys on the environment in general, renewable energy in general, and wind energy in particular in that order, using data gathered from polling in the U.S., the United Kingdom, and Canada. At this writing, more than 16 years after the first wind plants began going up in California, there is a solid and growing body of information available on public acceptance of wind energy. This paper draws on more than 25 surveys conducted over the years on wind and renewables, as well as individual findings on attitudes on the environment from other polls. An abbreviated summary of the public attitudes reviewed in this document is as follows: Views on the Environment: Public concern about protecting the environment, and particularly those aspects of the environment that relate to human health, such as

    ?This project represents the third phase of a multi-year effort to develop and bring to market a High Performance Manufactured Home (HPMH). The scope of this project involved building four HPMH prototypes, resulting in what is expected to be a 30% savings relative to the Building America Benchmark. (The actual % savings varies depending on choice of heating equipment and climate zone). The HPMH home is intended to make significant progress toward performing as zero-net-energy ready. Previous phases of this project created a HPMH specification and prototyped individual measures from the package to obtain engineering approvals and develop preliminary factory construction processes. This report describes the project team's work during 2014 to build prototype homes to the HPMH specifications and to monitor the homes for energy performance and durability during 2014. Monitoring is expected to continue into 2016.

  20. Taxing energy to improve the environment. Efficiency and distributional effects

    International Nuclear Information System (INIS)

    The effects of environmental tax policy in a dynamic overlapping-generations model of a small open economy with environmental quality incorporated as a durable consumption good have been studied. Raising the energy tax may deliver an efficiency gain if agents care enough about the environment. The benefits are unevenly distributed across generations since capital ownership, and the capital loss induced by a tax increase, rises with age. A suitable egalitarian bond policy can be employed in order to ensure everybody gains to the same extent. With this additional instrument the optimal energy tax can be computed. The authors further considered a tax reform that simultaneously lowers labour taxation and raises the energy tax. This policy delivers qualitatively similar consequences as the first scenario, though all changes are less pronounced. A double dividend may appear soon after the reform but vanishes in the course of the transition. 22 refs

  1. International Development Partnerships and Diffusion of Renewable Energy Technologies in Developing Countries: Cases in Latin America

    Science.gov (United States)

    Platonova, Inna

    Access to energy is vital for sustainable development and poverty alleviation, yet billions of people in developing countries continue to suffer from constant exposure to open fires and dangerous fuels, such as kerosene. Renewable energy technologies are being acknowledged as suitable solutions for remote rural communities in much of the developing world and international development non-governmental organizations (NGOs) increasingly play important roles in the diffusion of these technologies via development partnerships. While these partnerships are widely promoted, many questions related to their functioning and effectiveness remain open. To advance the theory and practice, this interdisciplinary exploratory research provides in-depth insights into the nature of international NGO-driven development partnerships in rural renewable energy and their effectiveness based on the case studies in Talamanca, Costa Rica and Cajamarca, Peru. The analysis of the nature of development partnerships shows that partnerships in the case studies differ in structure, size and diversity of actors due to differentiation in the implementation strategies, technological complexities, institutional and contextual factors. A multi-theoretical approach is presented to explain the multiple drivers of the studied development partnerships. The research highlights partnership constraints related to the provision of rural renewable energy, the organizational type and institutional environments. Based on the case studies this research puts forward theoretical propositions regarding the factors that affect the effectiveness of the partnerships. In terms of the partnership dynamics dimension, several key factors of success are confirmed from the existing literature, namely shared values and goals, complementary expertise and capacities, confidence and trust, clear roles and responsibilities, effective communication. Additional factors identified are personality match and continuity of staff. In

    This best practices guide is the twelfth in a series of guides for builders produced by PNNL for the U.S. Department of Energy’s Building America program. This guide book is a resource to help builders design and construct homes that are among the most energy-efficient available, while addressing issues such as building durability, indoor air quality, and occupant health, safety, and comfort. With the measures described in this guide, builders in the cold and very cold climates can build homes that have whole-house energy savings of 40% over the Building America benchmark with no added overall costs for consumers. The best practices described in this document are based on the results of research and demonstration projects conducted by Building America’s research teams. Building America brings together the nation’s leading building scientists with over 300 production builders to develop, test, and apply innovative, energy-efficient construction practices. Building America builders have found they can build homes that meet these aggressive energy-efficiency goals at no net increased costs to the homeowners. Currently, Building America homes achieve energy savings of 40% greater than the Building America benchmark home (a home built to mid-1990s building practices roughly equivalent to the 1993 Model Energy Code). The recommendations in this document meet or exceed the requirements of the 2009 IECC and 2009 IRC and thos erequirements are highlighted in the text. This document will be distributed via the DOE Building America website: www.buildingamerica.gov.

  3. Heuristic Scheduling in Grid Environments: Reducing the Operational Energy Demand

    Science.gov (United States)

    Bodenstein, Christian

    In a world where more and more businesses seem to trade in an online market, the supply of online services to the ever-growing demand could quickly reach its capacity limits. Online service providers may find themselves maxed out at peak operation levels during high-traffic timeslots but too little demand during low-traffic timeslots, although the latter is becoming less frequent. At this point deciding which user is allocated what level of service becomes essential. The concept of Grid computing could offer a meaningful alternative to conventional super-computing centres. Not only can Grids reach the same computing speeds as some of the fastest supercomputers, but distributed computing harbors a great energy-saving potential. When scheduling projects in such a Grid environment however, simply assigning one process to a system becomes so complex in calculation that schedules are often too late to execute, rendering their optimizations useless. Current schedulers attempt to maximize the utility, given some sort of constraint, often reverting to heuristics. This optimization often comes at the cost of environmental impact, in this case CO 2 emissions. This work proposes an alternate model of energy efficient scheduling while keeping a respectable amount of economic incentives untouched. Using this model, it is possible to reduce the total energy consumed by a Grid environment using 'just-in-time' flowtime management, paired with ranking nodes by efficiency.

    The international Symposium on Clusters and Nanostructures was held in Richmond, Virginia during November 7-10, 2011. The symposium focused on the roles clusters and nanostructures play in solving outstanding problems in clean and sustainable energy, environment, and health; three of the most important issues facing science and society. Many of the materials issues in renewable energies, environmental impacts of energy technologies as well as beneficial and toxicity issues of nanoparticles in health are intertwined. Realizing that both fundamental and applied materials issues require a multidisciplinary approach the symposium provided a forum by bringing researchers from physics, chemistry, materials science, and engineering fields to share their ideas and results, identify outstanding problems, and develop new collaborations. Clean and sustainable energy sessions addressed challenges in production, storage, conversion, and efficiency of renewable energies such as solar, wind, bio, thermo-electric, and hydrogen. Environmental issues dealt with air- and water-pollution and conservation, environmental remediation and hydrocarbon processing. Topics in health included therapeutic and diagnostic methods as well as health hazards attributed to nanoparticles. Cross-cutting topics such as reactions, catalysis, electronic, optical, and magnetic properties were also covered.

    High expectations for Norway's Centres for Environment-friendly Energy Research (FME).The FME centres address a broad range of areas, allcentral to developing the energy sector of the future. The activities of the eight centres established in 2009 focus on renewable energy, raising energy efficiency, energy planning, and carbon capture and storage (CCS). In 2011 three new FME centres were established which focus on social science-related energy research. The FME scheme is a direct follow-up of the broad-based political agreement on climate policy achieved in the Storting in January 2008, and of the national RandD Energi21 strategy submitted in February 2008 to the Ministry of Petroleum and Energy. In April 2008 the Research Council of Norway's Executive Board decided to launch a process to establish centres for environment-friendly energy research, and a funding announcement was issued that same year. In 2010 it was decided that additional FME centres would be established in the field of social science-related energy research. After a thorough assessment of each project (based on feasibility, scientific merit, potential to generate value creation and innovation, and composition of the consortium) eight applicants were selected to become FME centres in February 2009. A new call for proposals was issued in 2010, and three more centres were awarded FME status in February 2011. The objective of the FME scheme is to establish time-limited research centres which conduct concentrated, focused and long-term research of high international calibre in order to solve specific challenges in the energy sphere. The selected centres must exhibit higher goals, a longer-term perspective and a more concentrated focus than is required under other funding instruments for the same scientific area. The make-up of the centres is critical to achieving this objective. The centres bring together Norway's leading research institutions and key players in private enterprise, the

    Over the last ~15 years, the central goal in external beam radiotherapy of maximizing dose to the tumor while minimizing dose to surrounding normal tissues has been greatly facilitated by the development and clinical implementation of many innovations. These include megavoltage active matrix flat-panel imagers (MV AMFPIs) designed to image the treatment beam, and separate kilovoltage (kV) AMFPIs and x-ray sources designed to provide high-contrast projection and cone-beam CT images in the treatment room. While these systems provide clinically valuable information, a variety of advantages would accrue through introduction of the capability to produce clinically useful, high quality imaging information at multiple energies (e.g., kV and MV) from a single detector along the treatment beam direction. One possible approach for achieving this goal involves substitution of the x-ray converters used in conventional MV AMFPIs with thick, segmented crystalline scintillators designed for dual-energy operation, coupled with the addition of x-ray imaging beams that contain a significant diagnostic component. A second approach involves introduction of a large area, monolithic array of photon counting pixels with multiple energy thresholds and event counters, which could provide multi-spectral views of the treatment beam with improved contrast. In this paper, the motivations behind, and the merits of each approach are described. In addition, prospects for such dual-energy imagers and photon counting array designs are discussed in the context of the radiotherapy environment.

  14. Energy demand, poverty and the urban environment in Jordan

    International Nuclear Information System (INIS)

    This paper presents some insights into the prime problems of energy and related environmental issues as well as urbanisation in Jordan. The country has very limited natural resources: water is scarce; arable land is limited; and fossil-fuel sources are few. Moreover, the population is increasing rapidly. Hence, problems are arising. During the last 30 years, the country has experienced vast changes in its infrastructure with respect to the housing, urbanisation, commerce, agriculture and industry. Such developments have led to increasing demographic stresses: unemployment has increased and poverty is experienced by more than half of the population. The pressures have resulted in a high percentage of the population moving from rural to urban areas and so society is becoming less self-sufficient. At present, energy consumption in the residential sector accounts for about one quarter of the kingdom's fuel consumption. Kerosene, bottled LPG, diesel fuel and electricity are the main forms of energy used by households, but kerosene is still the dominant fuel because about 83% of households depend on it for space and water heating. The use of open fires and/or portable stoves has led to an increasing number of people being killed each year by suffocation or suffering health problems due to the inhalation of fumes and gaseous pollutants. Thus a national plan to achieve energy thrift and protect the environment, as well as accomplish the more rational utilisation of the limited natural resources available, is urgently needed and should be enacted soon.

    2013-01-01

    Full Text Available It is difficult to fully satisfy the energy demand of today’s society with renewables. Nevertheless, most of the energy we use is lost as non-functional waste energy, whereas a large part of the built environment’s energy demand is only for low-quality energy, so the initial demand for primary, high-quality energy can be reduced by more effective usage, such as by low-exergy means. Gaining insight into the parameters of energy demands and local renewable and residual energy potentials enables matching energy demand with a fitting potential, not only concerning quantity but taking into account location, temporality and quality as well. The method of Energy Potential Mapping (EPM aims to visualise the energy potentials and demands by making information of quantity, quality and location of demand and supply accessible. The aspect of quality specifically applies to heat and cold. The methodology of EPM will be described and explained with case studies. The focus specifically lies on mapping heat (and cold, one of the main reasons for energy demand in the built environment. The visualisation of exergy, to be simplified as the quality of energy, becomes an extra parameter in the case of Dutch Heat Maps. These maps can help finding opportunities of practical implementations of exchanging or cascading heat or cold. This way EPM and Heat Mapping (HM enables application of exergy principles in the built environment. EPM and HM can be seen as a local energy catalogue and can be useful in spatial planning for energy-based urban and rural plans.

  18. Climate variability and human impact on the environment in South America during the last 2000 years: synthesis and perspectives

    Directory of Open Access Journals (Sweden)

    S. G. A. Flantua

    2015-07-01

    Full Text Available An improved understanding of present-day climate variability and change relies on high-quality data sets from the past two millennia. Global efforts to reconstruct regional climate modes are in the process of validating and integrating paleo-proxies. For South America, however, the full potential of vegetation records for evaluating and improving climate models has hitherto not been sufficiently acknowledged due to its unknown spatial and temporal coverage. This paper therefore serves as a guide to high-quality pollen records that capture environmental variability during the last two millennia. We identify the pollen records with the required temporal characteristics for PAGES-2 ka climate modelling and we discuss their sensitivity to the spatial signature of climate modes throughout the continent. Diverse patterns of vegetation response to climate change are observed, with more similar patterns of change in the lowlands and varying intensity and direction of responses in the highlands. Pollen records display local scale responses to climate modes, thus it is necessary to understand how vegetation-climate interactions might diverge under variable settings. Additionally, pollen is an excellent indicator of human impact through time. Evidence for human land use in pollen records is useful for archaeological hypothesis testing and important in distinguishing natural from anthropogenically driven vegetation change. We stress the need for the palynological community to be more familiar with climate variability patterns to correctly attribute the potential causes of observed vegetation dynamics. The LOTRED-SA-2 k initiative provides the ideal framework for the integration of the various paleoclimatic sub-disciplines and paleo-science, thereby jumpstarting and fostering multi-disciplinary research into environmental change on centennial and millennial time scales.

    2006-02-21

    The Energy and Environment Directorate (E& ED) is one of 13 directorates at Lawrence Livermore National Laboratory (LLNL), which is operated by the University of California (UC) for the U.S. Department of Energy's National Nuclear Security Administration (NNSA). We operate in the context of a national security laboratory and focus on meeting major national needs, especially from a long-term perspective. In the LLNL context, E&ED is a hybrid ''program'' and ''discipline'' directorate, combining the program development responsibilities in the national energy and environment arenas to the benefit of the entire Laboratory and also serving as the Laboratory's science base of atmospheric, earth, environmental, and energy science. This Status Report is part of the annual evaluation process required by the Department of Energy (DOE) as part of its contract with UC. The annual review typically will focus on about one third of the activities and programs of a directorate, so that the entire organization is evaluated over a three-year window. This year's review is focused on the basic science foundations for the directorate and two major program areas in the directorate, with an update from a third program. The programs for review are: (1) Earth System Science and Engineering; (2) Nuclear Systems Science and Engineering; and (3) NARAC/IMAAC update. Major questions to be addressed during this review include: (1) Are the programmatic directions appropriate? How can they be improved? (2) What actions can E&ED take to ensure success? How well poised for success are the current staff and facilities? What additions are needed? (3) What recommendations can be made to the Director and the University? This Status Report provides background information on the entire directorate including the parts of the directorate that are the focus of this year's review by the Energy and Environment Directorate Review Committee, to be held

    1997-11-01

    This is the final report of a one-year, Laboratory Directed Research and Development (LDRD) project at Los Alamos National Laboratory (LANL). Fluxes of water and energy at the near-surface environment are tightly interrelated with a heterogeneous vegetation pattern that is a mosaic of tree canopies and intercanopy area. The objective was to improve the ability to predict these interrelationships, which are not well quantified. The authors (1) quantified how vegetation overstory determines the patterns of soil moisture and near-ground solar radiation, (2) developed spatial neighborhood analyses that demonstrated how woody plants exploit canopy/intercanopy heterogeneity, (3) developed a spatially explicit model for predicting near-ground solar radiation for sites along a grassland-forest continuum, (4) developed a water balance model that predicted temporal shifts in soil moisture between canopy and intercanopy patches, and (5) used the collective results to assess large-scale ecosystem responses to climate variations that lead to accelerated soil erosion.

  4. Analysis of renewable energy incentives in the Latin America and Caribbean region: The feed-in tariff case

    International Nuclear Information System (INIS)

    Renewable energy is becoming a priority for Latin America and Caribbean (LAC) countries because of energy challenges such as demand growth, high dependence on imported fossil fuels, and climate change. As of 2010, 12 LAC countries have implemented formal targets for renewable energy deployment. Some of the LAC countries, namely Argentina, Dominican Republic, Ecuador, Honduras, and Nicaragua, are using feed-in tariffs (FITs) to promote renewables. FITs are long-term, guaranteed purchase agreements for green electricity at a price that can provide project developers a reasonable return on investment. FITs are increasingly popular because if designed well, they can mitigate investor risk in renewables. This article presents a low-risk FIT design and then uses this design to benchmark the existing LAC region FITs. - Highlights: ► 12 LAC countries have implemented formal targets for renewable energy deployment. ► Argentina, Dominican Republic, Ecuador, Honduras, and Nicaragua, are using feed-in tariffs (FITs) to promote renewables. ► Low-risk FIT design of feed-in tariffs in the LAC region can be improved

    2015-01-01

    The rise of miniaturized artificial self-powered devices, demonstrating autonomous motion, has brought in new considerations from the environmental perspective. This review addresses the interplay between these nano/micro/macromotors and the environment, recent advances, and their applications in pollution management. Such self-propelled devices are able to actuate chemical energy into mechanical motion in situ, adding another powerful dimension towards solving environmental problems. Use of synthetic nano/micro/macromotors has demonstrated potential in environmental remediation, both in pollutant removal and contaminant degradation, owing to motion-induced mixing. At the same time, the chemical environment exerts influence on the locomotion of the motors. These sensitized self-powered devices demonstrate capabilities for being deployed as sensors and their chemotactic behaviors show efficacy to act as first responders towards a chemical leakage. Thus, the notion of a self-propelling entity also entails further investigation into its inherent toxicity and possible implications as a pollutant. Future challenges and outlook of the use of these miniaturized devices are discussed, with specific regard to the fields of environmental remediation and monitoring, as we move towards their wider acceptance. We believe that these tiny machines will stand up to the task as solutions for environmental sustainability in the 21st century. PMID:25410790

    A basin-scale hydrologic-energy balance model that integrates modern climatological, hydrological, and hypsographic observations was developed for the modern Lake Titicaca watershed (northern Altiplano, South America) and operated under variable conditions to understand controls on post-glacial changes in lake level. The model simulates changes in five environmental variables (air temperature, cloud fraction, precipitation, relative humidity, and land surface albedo). Relatively small changes in three meteorological variables (mean annual precipitation, temperature, and/or cloud fraction) explain the large mid-Holocene lake-level decrease ({proportional_to}85 m) inferred from seismic reflection profiling and supported by sediment-based paleoproxies from lake sediments. Climatic controls that shape the present-day Altiplano and the sediment-based record of Holocene lake-level change are combined to interpret model-derived lake-level simulations in terms of changes in the mean state of ENSO and its impact on moisture transport to the Altiplano.

    This study extends the recent work of Ang (2007) [Ang, J.B., 2007. CO{sub 2} emissions, energy consumption, and output in France. Energy Policy 35, 4772-4778] in examining the causal relationship between carbon dioxide emissions, energy consumption, and output within a panel vector error correction model for six Central American countries over the period 1971-2004. In long-run equilibrium energy consumption has a positive and statistically significant impact on emissions while real output exhibits the inverted U-shape pattern associated with the Environmental Kuznets Curve (EKC) hypothesis. The short-run dynamics indicate unidirectional causality from energy consumption and real output, respectively, to emissions along with bidirectional causality between energy consumption and real output. In the long-run there appears to be bidirectional causality between energy consumption and emissions. (author)

  10. Building America Case Study: Multifamily Zero Energy Ready Home Analysis, Elmsford, New York

    Energy Technology Data Exchange (ETDEWEB)

    2016-04-01

    Two multifamily buildings planned in Climate Zone 4 were analyzed to determine the cost, energy and performance implications of redesigning them to comply with Zero Energy Ready Home, a recognition program of the U.S. Department of Energy. Energy modeling was conducted on one representative apartment in each building using BEopt. Construction costs were obtained from the developer and subcontractors to determine savings and cost increases over ENERGY STAR. It was found that seven items would be necessary to change to comply with ZERH criteria when starting from the original design which was compliant with ENERGY STAR version 3.0. Design changes were made to the exterior walls, domestic water heating system, duct protection, duct design, garage ventilation, and pest control to comply with ZERH requirements. Energy impacts of upgrading from the original design to ZERH resulted in 2 to 8 percent reduction in modeled source energy consumption, or 1.7 to 10.4 MMBtu per year, although the original design was already about 8 percent better than a design configured to minimum ENERGY STAR criteria. According to the BEopt analysis, annualized energy related costs of the ZERH design were slightly higher for the apartment and slightly lower for the townhome when compared to the original design.

    Our study investigates how factors, such as latitude, productivity, and several environmental variables, influence contemporary patterns of the species richness in North American turtles. In particular, we test several hypotheses explaining broad-scale species richness patterns on several species richness data sets: (i) total turtles, (ii) freshwater turtles only, (iii) aquatic turtles, (iv) terrestrial turtles only, (v) Emydidae, and (vi) Kinosternidae. In addition to spatial data, we used a combination of 25 abiotic variables in spatial regression models to predict species richness patterns. Our results provide support for multiple hypotheses related to broad-scale patterns of species richness, and in particular, hypotheses related to climate, productivity, water availability, topography, and latitude. In general, species richness patterns were positively associated with temperature, precipitation, diversity of streams, coefficient of variation of elevation, and net primary productivity. We also found that North America turtles follow the general latitudinal diversity gradient pattern (i.e., increasing species richness towards equator) by exhibiting a negative association with latitude. Because of the incongruent results among our six data sets, our study highlights the importance of considering phylogenetic constraints and guilds when interpreting species richness patterns, especially for taxonomic groups that occupy a myriad of habitats.

    2002-05-16

    To support the North American Energy Working Group's Expert Group on Energy Efficiency (NAEWG-EE), USDOE commissioned the Collaborative Labeling and Appliance Standards Program (CLASP) to prepare a resource document comparing current standards, labels, and test procedure regulations in Canada, Mexico, and the United States. The resulting document reached the following conclusions: Out of 24 energy-using products for which at least one of the three countries has energy efficiency regulations, three products -- refrigerators/freezers, split system central air conditioners, and room air conditioners -- have similar or identical minimum energy performance standards (MEPS) in the three countries. These same three products, as well as three-phase motors, have similar or identical test procedures throughout the region. There are 10 products with different MEPS and test procedures, but which have the short-term potential to develop common test procedures, MEPS, and/or labels. Three other noteworthy areas where possible energy efficiency initiatives have potential for harmonization are standby losses, uniform endorsement labels, and a new standard or label on windows. This paper explains these conclusions and presents the underlying comparative data.

  15. Nuclear energy, its social impact to the environment. The renewable energy sources, a viable alternative

    International Nuclear Information System (INIS)

    The authors present arguments against nuclear energy and pro renewable energy sources. Thus, the water used in Uranium mining and primary ore processing becomes contaminated in long lived radioisotopes and so a threat for local ecosystems and communities. Then, during the fabrication, enrichment, and handling of nuclear fuel the workers are exposed to radiations and dangerous accidental radioactive leaks can occur. But, by far, the most menacing aspect of nuclear power exploitation remains the human errors in operating the nuclear plants which can result in major accidents like that from Chernobyl which spread radioactivity all over the Europe. The equipment used in nuclear facilities which is highly contaminated as well as the burned fuel implies transportation and long term storage which also present high risks. The major advantage of the nuclear energy consists in its very low environment impact and its null contribution to the greenhouse effect. In contrast, the renewable energy sources appear to be both increasingly cheaper and more safe for man and environment. The authors present a list of twelve major advantages pleading in favour of development of renewable energy technology

    2006-01-15

    This report represents North America's contribution to the global initiative to promote environmental and child health protection. It indicates that despite improvements in many areas, children remain at risk from environmental threats. The report focuses on the following 3 priority areas: asthma and respiratory disease; lead and other chemicals, including pesticides and waterborne diseases. This document is the first integrated, regional report providing indicators for a series of children's health and environment issues. It is intended to increase awareness of the relationship between environmental risks and children's health and to provide a means of measuring and promoting change. An introduction to the participating countries was included along with population data, birth rates, child mortality, immunization rates and socioeconomic determinants of health. The affect of outdoor and indoor air pollution on asthma and respiratory disease in Canada, Mexico and the United States was discussed along with blood lead levels and the affect of lead in the home, as well as industrial releases of lead, chemicals and pesticides. Drinking water and sanitation issues were also discussed with reference to the link with waterborne diseases. It was concluded that more effort in trilateral collaboration is needed to improve the quality of future reports. Some observations and opportunities for improvement were noted. figs.

    Energy Technology Data Exchange (ETDEWEB)

    Dammer, D.

    1996-01-01

    This paper describes the application of energy-efficient lighting in a retail environment, specifically a supermarket. It will reveal the general theory behind Big V`s chosen lighting design, and then discuss two examples of the application: one, a retrofit to an existing supermarket; the other, the adaption of the design to a new store. The factors that influence Big V`s lighting design are: (1) the best presentation of product for merchandising purposes, and (2) the lowest operating cost. These two factors can often be mutually exclusive. For merchandising purposes, the best design would make the product `jump off the shelf` at a customer, preferably into his/her shopping cart. Such an arrangement would include high footcandle levels along with a very high color rendering index (CRI). To design only to these requirements would result in very high original and operating costs for the lighting system. However, to base the design on cost considerations alone would result in low light levels at a very low CRI. Since neither option is acceptable, Big V`s design is a compromise, combining the best light quality at a reasonable cost.

    2016-04-01

    Kaplan Thompson Architects (KTA) has specialized in sustainable, energy-efficient buildings, and they have designed several custom, zero-energy homes in New England. These zero-energy projects have generally been high-end, custom homes with budgets that could accommodate advanced energy systems. In an attempt to make zero energy homes more affordable and accessible to a larger demographic, KTA explored modular construction as way to provide high-quality homes at lower costs. In mid-2013, KTA formalized this concept when they launched BrightBuilt Home (BBH). The BBH mission is to offer 'a line of architect-designed, high-performance homes that are priced to offer substantial savings off the lifetime cost of a typical home and can be delivered in less time.' For the past two years, CARB has worked with BBH and Keiser Homes (the primary modular manufacturer for BBH) to discuss challenges related to wall systems, HVAC, and quality control. In Spring of 2014, CARB and BBH began looking in detail on a home to be built in Lincolnville, Maine, by Black Bros. Builders. This report details the solution package specified for this modular plan and the challenges that arose during the project.

    2011-03-01

    A parametric study was conducted using EnergyPlus version 6.0 to investigate humidity issues on a typical mid-1990s reference home, a 2006 International Energy Conservation Code home, and a high-performance home in a hot-humid climate. The impacts of various dehumidification equipment and controls are analyzed on the high performance home. The study examined the combined effects of infiltration and mechanical ventilation with balanced and unbalanced mechanical ventilation systems. Indoor relative humidity excursions were examined; specifically, the number of excursions, average excursion length, and maximum excursion length. Space relative humidity, thermal comfort, and whole-house source energy consumption were analyzed for indoor relative humidity set points of 50%, 55%, and 60%. The study showed and explained why similar trends of high humidity were observed in all three homes regardless of energy efficiency, and why humidity problems are not necessarily unique in high-performance homes. Thermal comfort analysis indicated that occupants are unlikely to notice indoor humidity problems. The study confirmed that supplemental dehumidification should be provided to maintain space relative humidity below 60% in a hot-humid climate.

  4. Building America Case Study: Philadelphia Housing Authority Energy-Efficiency Turnover Protocols, Philadelphia, Pennsylvania

    Energy Technology Data Exchange (ETDEWEB)

    2016-02-01

    Over one million HUD-supported public housing units provide rental housing for eligible low-income families across the country. A survey of over 100 public housing authorities (PHAs) across the country indicated that there is a high level of interest in developing low-cost solutions that improve energy efficiency and can be seamlessly included in the refurbishment process. Further, PHAs, have incentives (both internal and external) to reduce utility bills. ARIES worked with four PHAs to develop packages of energy efficiency retrofit measures the PHAs can cost-effectively implement with their own staffs in the normal course of housing operations at the time when units are refurbished between occupancies. The energy efficiency turnover protocols emphasized air infiltration reduction, duct sealing, and measures that improve equipment efficiency. ARIES documented implementation in 18 housing units. Reductions in average air leakage were 16 percent and duct leakage reductions averaged 23 percent. Total source energy consumption savings due to implemented measures was estimated at 3-10 percent based on BEopt modeling with a simple payback of 1.6 to 2.5 years. Implementation challenges were encountered mainly related to required operational changes and budgetary constraints. Nevertheless, simple measures can feasibly be accomplished by PHA staff at low or no cost. At typical housing unit turnover rates, these measures could impact hundreds of thousands of units per year nationally.

  5. Feasibility study of porous media compressed air energy storage in South Carolina, United States of America

    Science.gov (United States)

    Jarvis, Alexandra-Selene

    Renewable Energy Systems (RES) such as solar and wind, are expected to play a progressively significant role in electricity production as the world begins to move away from an almost total reliance on nonrenewable sources of power. In the US there is increasing investment in RES as the Department of Energy (DOE) expands its wind power network to encompass the use of offshore wind resources in places such as the South Carolina (SC) Atlantic Coastal Plain. Because of their unstable nature, RES cannot be used as reliable grid-scale power sources unless power is somehow stored during excess production and recovered at times of insufficiency. Only two technologies have been cited as capable of storing renewable energy at this scale: Pumped Hydro Storage and Compressed Air Energy Storage (CAES). Both CAES power plants in existence today use solution-mined caverns as their storage spaces. This project focuses on exploring the feasibility of employing the CAES method to store excess wind energy in sand aquifers. The numerical multiphase flow code, TOUGH2, was used to build models that approximate subsurface sand formations similar to those found in SC. Although the aquifers of SC have very low dips, less than 10, the aquifers in this study were modeled as flat, or having dips of 00. Cycle efficiency is defined here as the amount of energy recovered compared to the amount of energy injected. Both 2D and 3D simulations have shown that the greatest control on cycle efficiency is the volume of air that can be recovered from the aquifer after injection. Results from 2D simulations showed that using a dual daily peak load schedule instead of a single daily peak load schedule increased cycle efficiency as do the following parameters: increased anisotropy, screening the well in the upper portions of the aquifer, reduced aquifer thickness, and an initial water displacement by the continuous injection of air for at least 60 days. Aquifer permeability of 1x10-12 m2 produced a cycle

  7. Energy Return on Energy Invested for Tight Gas Wells in the Appalachian Basin, United States of America

    Directory of Open Access Journals (Sweden)

    2011-10-01

    Full Text Available The energy cost of drilling a natural gas well has never been publicly addressed in terms of the actual fuels and energy required to generate the physical materials consumed in construction. Part of the reason for this is that drilling practices are typically regarded as proprietary; hence the required information is difficult to obtain. We propose that conventional tight gas wells that have marginal production characteristics provide a baseline for energy return on energy invested (EROI analyses. To develop an understanding of baseline energy requirements for natural gas extraction, we examined production from a mature shallow gas field composed of vertical wells in Pennsylvania and materials used in the drilling and completion of individual wells. The data were derived from state maintained databases and reports, personal experience as a production geologist, personal interviews with industry representatives, and literature sources. We examined only the “upstream” energy cost of providing gas and provide a minimal estimate of energy cost because of uncertainty about some inputs. Of the materials examined, steel and diesel fuel accounted for more than two-thirds of the energy cost for well construction. Average energy cost per foot for a tight gas well in Indiana County is 0.59 GJ per foot. Available production data for this natural gas play was used to calculate energy return on energy invested ratios (EROI between 67:1 and 120:1, which depends mostly on the amount of materials consumed, drilling time, and highly variable production. Accounting for such inputs as chemicals used in well treatment, materials used to construct drill bits and drill pipe, post-gathering pipeline construction, and well completion maintenance would decrease EROI by an unknown amount. This study provides energy constraints at the single-well scale for the energy requirements for drilling in geologically simple systems. The energy and monetary costs of wells from

    2009-01-01

    Concern over climate change has led the U.S. to consider a cap-and-trade system to regulate emissions. Here we illustrate the land-use impact to U.S. habitat types of new energy development resulting from different U.S. energy policies. We estimated the total new land area needed by 2030 to produce energy, under current law and under various cap-and-trade policies, and then partitioned the area impacted among habitat types with geospatial data on the feasibility of production. The land-use intensity of different energy production techniques varies over three orders of magnitude, from 1.9–2.8 km2/TW hr/yr for nuclear power to 788–1000 km2/TW hr/yr for biodiesel from soy. In all scenarios, temperate deciduous forests and temperate grasslands will be most impacted by future energy development, although the magnitude of impact by wind, biomass, and coal to different habitat types is policy-specific. Regardless of the existence or structure of a cap-and-trade bill, at least 206,000 km2 will be impacted without substantial increases in energy efficiency, which saves at least 7.6 km2 per TW hr of electricity conserved annually and 27.5 km2 per TW hr of liquid fuels conserved annually. Climate policy that reduces carbon dioxide emissions may increase the areal impact of energy, although the magnitude of this potential side effect may be substantially mitigated by increases in energy efficiency. The possibility of widespread energy sprawl increases the need for energy conservation, appropriate siting, sustainable production practices, and compensatory mitigation offsets. PMID:19707570

  10. New Zealand and Australia wind energy in a non subsidised market environment

    Energy Technology Data Exchange (ETDEWEB)

    Lieshout, P. van [DesignPower New Zealand Ltd., Wellington (New Zealand)

    1996-12-31

    Significant preliminary work has been undertaken by New Zealand and Australian Power/Generation Companies regarding Wind Power. Turbines are installed in Australia and New Zealand to test the wind and the technical applicability in the Australian wind diesel and the New Zealand high wind speed environment. Projects in Esperance, Thursday Island and King Island illustrate hybrid wind diesel applications. A single Wind Turbine Generator (WTG) has been successfully operated in New Zealand for the last 3 years. A new 3.5 MW wind farm is operational and Resource Consent has been granted for a 65 MW wind farm in New Zealand. Design Power is very proud to be involved in many of the New Zealand and Australian projects. It is obvious that wind power is just starting here, however the start has been promising and it is expected that wind power is here to stay. This paper will address some of the issues associated with wind power in New Zealand and Australia, particularly those that are different from Europe and America. It shows the opportunities and challenges regarding the operation of WTGs in these countries. It addresses the non subsidized electrical pricing structure and the influence of the economically necessary high wind speeds or diesel systems on the choice of technology, particularly the control algorithm of WTGs and the subsystems. It reviews several of the issues associated with predicting the amount of energy that a WTG can generate, again taking into account the high wind speed control algorithms. It further addresses the issue of embedded generation and the influence that a wind farm might have on the electrical network. It continues to address issues associated with wind diesel systems. The paper concludes that wind power will be viable in the near future both in New Zealand and Australia, but also that care should be taken with data analysis and hardware choices during the next phase of implementation of wind power in New Zealand and Australia. 7 figs.

  11. Energy 2000 Investment Programme - Effects on the economy, energy and environment

    International Nuclear Information System (INIS)

    This comprehensive final report for the Swiss Federal Office of Energy presents the results of an evaluation made of the Energy 2000 Investment Programme which was launched to stimulate the economy and help meet Switzerland's goals in the energy sector. The aims of the evaluation and the methods used are discussed. The implementation of the programme, which provided financial support for energy-relevant projects implemented by private persons and institutions, is described and comments are made on the results obtained in the various regions of Switzerland. Further, the problems encountered, such as the economic situation, the shortage of energy consultants in western Switzerland, the short time available for the programme's implementation and the limited possibilities of spreading information in the heating, ventilation and air-conditioning sector are discussed. Also, the so-called 'go-along' effect - the unintentional support of projects that would have been realised anyway - is described. The positive results of the programme - in particular the correct and efficient implementation of those projects it supported - are mentioned. The last part of the report describes the impact of the programme on the Swiss economy, the consumption and use of energy and on the environment and presents appropriate figures

  12. Wind energy technology: an option for a renewable clean environment energy. Low impact renewable energy: options for a clean environment and healthy Canadian economy

    International Nuclear Information System (INIS)

    As Canada debates ways to address climate change, the country's low-impact renewable energy industries want to ensure that Canadians are provided with all of the options available to them. Accordingly, they have come together to create Options for a Clean Environment and Healthy Canadian Economy. Recognizing there is no 'silver bullet' solution to climate change, this document identifies an important suite of measures that, along with others, will allow Canada to achieve its long-term economic and environmental goals. The measures described in this document represent an investment in Canada's future. If implemented, they will reduce annual greenhouse gas (GHG) emissions by more than 12 million tonnes (Mt) by the year 2010 (roughly 8% of Canada's reduction target), create thousands of new jobs, and reduce health-care costs by millions of dollars each year. The most significant dividends from these measures, however, will occur after 2010 as a result of having set in motion fundamental changes in the attitudes of Canadians and the nature of the Canadian energy market. By 2020, the spin-off actions prompted by these measures will likely have resulted in GHG reductions twice as great as those achieved in 2010. This document highlights the opportunities associated specifically with Canada's low-impact renewable energy resources. These are non-fossil-fuel resources that are replenished through the earth's natural cycles and have a minimal impact on the environment and human health. They include wind, solar, earth energy, run-of-river hydro and sustainable biomass fuels. These resources can replace fossil fuels in a variety of areas, including electricity and space and water heating. Fuel cells, although not a renewable resource in themselves, are a promising technology that in combination with renewables have the potential to deliver versatile low-impact electricity. The document also identifies opportunities associated with the increased use of passive renewable energy

    Three recent publications have estimated the number of birds killed each year by wind energy facilities at 2012 build-out levels in the United States. The 3 publications differ in scope, methodology, and resulting estimates. We compare and contrast characteristics of the approaches used in the publications. In addition, we describe decisions made in obtaining the estimates that were produced. Despite variation in the 3 approaches, resulting estimates were reasonably similar; about a quarter- to a half-million birds are killed per year by colliding with wind turbines.

  14. The LAGO Collaboration: Searching for high energy GRB emissions in Latin America

    Barros, H.; Lago Collaboration

    2012-02-01

    During more than a decade Gamma Ray Bursts (GRB a cosmological phenomena of tremendous power) have been extensively studied in the keV - MeV energy range. However, the higher energy emission still remains a mystery. The Large Aperture GRB Observatory (L.A.G.O.) is an international collaboration started in 2005 aiming at a better understanding of the GRB by studying their emission at high energies (> 1 GeV), where the fluxes are low and measurements by satellites are difficult. This is done using the Single Particle Technique, by means of ground-based Water Cherenkov Detectors (WCD) at sites of high altitude. At those altitudes it is possible to detect air showers produced by high energy photons from the GRB, i. e. a higher rate of events on a short time scale, of the order of the second. The Pierre Auger Observatory could detect such GRB given its large number of detectors, but at 1400 m.a.s.l. the expected signal is quite small. At higher altitudes, similar performance is expected with only a very small number of WCD. As of 2011, high altitude WCD are in operation at Sierra Negra (Mexico, 4650 m.a.s.l.), Chacaltaya (Bolivia, 5200 m.a.s.l.), Maracapomacocha (Peru, 4200 m.a.s.l.), and new WCDs are being installed in Venezuela (Pico Espejo, 4750 m.a.s.l.), Argentina, Brazil, Chile, Colombia and Guatemala. Most of the new WCDs will not be at high enough altitude to detect GRB, never the less it will allow obtaining valuable measurements of secondaries at ground level, which are relevant for solar physics. The LAGO sensitivity to GRB is determined from simulations (under a sudden increase of 1 GeV - 1 TeV photons from a GRB) of the gamma initiated particle shower in the atmosphere and the WCD response to secondaries. We report on WDC calibration and operation at high altitude, GRB detectability, background rates, search for bursts in several months of preliminary data, as well as search for signals at ground level when satellite burst is reported, all these show the

  16. Quality audits of radiotherapy centres in Latin America: a pilot experience of the International Atomic Energy Agency

    International Nuclear Information System (INIS)

    In Latin America radiotherapy quality varies significantly among hospitals, where highly equipped academic centers coexist with others not meeting minimal requirements. In 2007, the International Atomic Energy Agency published guidelines for auditing radiotherapy centers, known as the “Quality Assurance Team for Radiation Oncology” (QUATRO) audits. The present report summarizes a pilot experience with QUATRO audits to 12 radiotherapy centres. The findings from QUATRO audits conducted in 12 radiotherapy centres in Latin America between 2008 and 2013 were analysed. Events representing weaknesses or gaps in the process of radiotherapy were recorded. Relevant data for estimating human and technological needs of visited centres were processed. The main difficulties and strengths faced by institutions were also documented. All 12 radiotherapy centres were successfully audited following the QUATRO method. IAEA provided a dosimetry kit for quality control. Forty percent of audited institutions were immersed in a health system that did not recognize cancer as a public health priority problem. With few exceptions, local training programs for physicists and technologists were scarce and research was not an activity of interest among physicians. Centres were provided with sufficient staff to meet the local demand, both in the case of radiation oncologists, physicists and radiation therapists. Three centres lacking the minimum infrastructure were identified. Three institutions did not perform gynaecological brachytherapy, and one installation delivered around 900 teletherapy treatments annually without simulation, planning or dosimetry equipment for that purpose. Recommendations to centres were classified as related to personnel, infrastructure, processes and institutional organizational aspects. Many recommendations warned governments about the evident need for allocating more budgetary resources to radiotherapy. Most recommendations pointed out different aspects related

    There is a need to reduce energy consumption in buildings and in general improve energy efficiency in the building sector in Denmark, as in the rest of the EU. Energy savings, however, should go hand in hand with providing a healthy and comfortable indoor environment. So, the aim of this thesis...... is to contribute to the development of Danish low-energy residential buildings with good indoor environment. To reach the target of a fossil-free energy supply in Denmark by 2050, both new building design and renovation of existing buildings to meet future energy requirements need to be taken into account...... with current and future energy requirements, the influence of window size, type and orientation on space heating demand and thermal indoor environment were investigated in EnergyPlus by comparing a window design with an even distribution (same glazingto-floor-area in each room) with a traditional window design...

  20. Renewable energies, development, and environment: discourses, realities, and perspectives

    International Nuclear Information System (INIS)

    After two contributions describing the context of renewable energies and their different objectives and roles in the North and in the South, a set of contributions discusses some controversies and generally accepted ideas about renewable energies: fossil energy appraisal and the greenhouse effect of presently used fuels, the issue of irregularity and climate hazards, photovoltaic energy as a development key for South countries, vulnerability of energy systems, renewable energies and energy market privatisation. The next set of contributions deals with different examples: renewable energies in Africa, electricity and high dams, small hydro developments in China, wind energy in Morocco, solar water-heaters in Tunisia, bio-energies and food security, second generation bio-fuels, biomass energy in Cambodia. Sheets are then proposed with a brief historical overview, a description of the state of the art, an indication of the installed power, of market shares, and a brief discussion of perspectives for the different renewable energy sources: large and small hydro, photovoltaic, thermodynamic solar, wind, geothermal, thermal solar, bio-fuels, biomass, and biogas

  1. Plasma simulations of emission line regions in high energy environments

    Science.gov (United States)

    Richardson, Chris T.

    This dissertation focuses on understanding two different, but in each case extreme, astrophysical environments: the Crab Nebula and emission line galaxies. These relatively local objects are well constrained by observations and are test cases of phenomena seen at high-z where detailed observations are rare. The tool used to study these objects is the plasma simulation code known as Cloudy. The introduction provides a brief summary of relevant physical concepts in nebular astrophysics and presents the basic features and assumptions of Cloudy. The first object investigated with Cloudy, the Crab Nebula, is a nearby supernova remnant that previously has been subject to photoionization modeling to reproduce the ionized emission seen in the nebula's filamentary structure. However, there are still several unanswered questions: (1) What excites the H2 emitting gas? (2) How much mass is in the molecular component? (3) How did the H2 form? (4) What is nature of the dust grains? A large suite of observations including long slit optical and NIR spectra over ionized, neutral and molecular gas in addition to HST and NIR ground based images constrain a particularly bright region of H2 emission, Knot 51, which exhibits a high excitation temperature of ˜3000 K. Simulations of K51 revealed that only a trace amount of H2 is needed to reproduce the observed emission and that H2 forms through an uncommon nebular process known as associative detachment. The final chapters of this dissertation focus on interpreting the narrow line region (NLR) in low-z emission line galaxies selected by a novel technique known as mean field independent component analysis (MFICA). A mixture of starlight and radiation from an AGN excites the gas present in galaxies. MFICA separates galaxies over a wide range of ionization into subsets of pure AGN and pure star forming galaxies allowing simulations to reveal the properties responsible for their observed variation in ionization. Emission line ratios can

    The total costs and impacts of expanding energy use in China will depend, in part, on a number of important factors, an understanding of which is vital for China's policy-makers. These issues include the additional environmental and public health impacts associated with energy use, the economic costs of infrastructure expansion to meet growing energy needs, and the potential role that renewable energy technologies could play if pushed hard in China's energy future. This short report summarizes major trends and issues in each of these three areas.

    2012-06-01

    Full Text Available Recently, environmental issues have been the focus of much of the world’s attention. This has stimulated a response in many countries, which has led to a closer examination of energy conservation strategies for conventional fossil fuels. One way of reducing building energy consumption is to design buildings, which are more economical in their use of energy for: heating, lighting, cooling, ventilation and hot water supply. Passive measures, particularly natural or hybrid ventilation rather than air-conditioning, can dramatically reduce primary energy consumption. However, exploitation of renewable energy in buildings and agricultural greenhouses, can significantly contribute in reducing dependency on fossil fuels. Therefore, promoting innovative renewable applications and reinforcing the renewable energy market will contribute to preserving the ecosystem by reducing emissions at local and global levels. This will also contribute to the amelioration of environmental conditions, through a reduction in air pollution and greenhouse gases, by the replacement of conventional fuels with renewable energies.

  4. Energy and environment in the ASEAN: challenges and opportunities

    International Nuclear Information System (INIS)

    The Association of Southeast Asian Nations (ASEAN) is one of the most dynamic economic regions of the world. Its economy is linked with its diverse energy resources, high-level urbanization, and rapid industrialization. ASEAN's growing economy in the last two decades has increased the concern of sustainable development in the face of deteriorating energy security, environmental pollution, and economic hardship in energy investment. However, opportunities exist to tackle these issues. Increasing energy efficiency (both supply and demand side), exploitation of renewable energy resources (mostly hydro), and an integrated approach on energy resource management are some of the important approaches toward the sustainable energy path. Because the options are capital-intensive, cooperation and development of appropriate institutional structures and decision mechanism across the region are urgently needed

    A first article discusses the different impacts that renewable energies may have on the environment, i.e. on the human environment (risks associated with dams, aesthetic impacts, impacts on landscapes, neighbouring nuisances) or on the natural environment (natural media, wildlife and flora). A second article outlines that the legal framework of hydroelectricity is rather old and therefore ignored (willingly or not?) environmental concerns whereas environmental impacts actually exist. Therefore, a new legal context must be defined, notably by taking into account objectives defined in the international and European Union law, in particularly the requirements related to ecological continuity

This report highlights the Commission’s findings and conclusions and presents recommendations for consideration by the Administration and Congress, as well as interested state, tribal and local governments, other stakeholders, and the public.

  10. Energy scope of handoff strategies in macro-femtocell environments

    KAUST Repository

    León, Jaime Peña

    2012-06-01

    Energy consumption in downlink mode is becoming an important topic as cellular communications grow into a large scale enterprise. The search for high rates keeping energy constraints low has put forward the idea that cells with smaller size may improve not only the capacity of the network, but also reduce the amount of energy that is needed to achieve such capacities. When using heterogeneous networks, users can be encouraged to handoff to a femtocell, that offers better capacity per unit energy spent, by means of different handoff strategies. These strategies may also improve the energy use of the network if the handoff priority is given to both, capacity, and energy use. © 2012 IEEE.

  14. Energy mechanism of charges analyzed in real current environment

    CERN Document Server

    Ianconescu, R; Ianconescu, Reuven

    2003-01-01

    We analyze in this work the energy transfer process of accelerated charges, the mass fluctuations accompanying this process, and their inertial properties. Based on a previous work, we use here the dipole antenna, which is a very convenient framework for such analysis, for analyzing those characteristics. We show that the radiation process can be viewed by two energy transfer processes: one from the energy source to the charges and the second from the charges into the surrounding space. Those processes, not being in phase, result in mass fluctuations. The same principle is true during absorption. We show that in a transient period between absorption and radiation the dipole antenna gains mass according to the amount of absorbed energy and loses this mass as radiated energy. We rigorously prove that the gain of mass, resulting from electrical interaction has inertial properties in the sense of Newton's third low. We arrive to this result by modeling the reacting spacetime region by an electric dipole.

    International Nuclear Information System (INIS)

    Fuel supply and demand mix as well as energy technology configuration are analyzed by the MARKAL model for the future Japanese energy system, when reduction of environmental emissions is taken into consideration. The Reference Energy System (RES) covers whole sectors, i.e., fuel conversion and energy transformation, industry, residential and commercial, and transportation sectors. Environmental emissions considered here are SOx, NOx, CO2, and radio activity, and the time horizon is an interval from 1985 to 2030. Both SOx and NOx emission can be reduced much by present art of reduction measures. From the view points of cost effectiveness, abatement technologies including fluegas treatments take the highest priority and fuel switching and technology substitution follow in this order. For CO2 reduction, both nuclear and renewable energy technologies are essential among them. (author)

  16. Impact of the Last Glacial Cycle on Late-Holocene temperature and energy reconstructions from terrestrial borehole temperatures in North America

    Directory of Open Access Journals (Sweden)

    H. Beltrami

    2014-05-01

    Full Text Available Reconstructions of past climatic changes from borehole temperature profiles are important independent estimates of temperature histories over the last millennium. There remain, however, multiple uncertainties in the interpretation of these data as climatic indicators and as estimates of the changes in heat content of the continental subsurface due to long-term climatic change. One of these uncertainties is associated with the often ignored impact of the last glacial cycle on the subsurface energy content, and on the estimate of the background quasi steady-state signal associated with the diffusion of accretionary energy from the Earth's interior. Here we provide the first estimate of the impact of the development of the Laurentide ice sheet on the estimates of energy and temperature reconstructions from measurements of terrestrial borehole temperatures in North America. We use basal temperature values from the data-calibrated Memorial University of Newfoundland Glacial Systems Model to quantify the extent of the perturbation to estimated steady-state temperature profiles and to derive spatial maps of the expected impacts on measured profiles over North America. Furthermore, we present quantitative estimates of the potential effects of temperature changes during the last glacial cycle on the borehole reconstructions over the last millennium for North America. The range of these possible impacts are estimated using synthetic basal temperatures for a period covering 120 ka to the present day that include the basal temperature history uncertainties from an ensemble of results from the calibrated numerical model. For all the locations, we find that within the depth ranges that are typical for available boreholes (≈600 m, the induced perturbations to the steady-state temperature profile are on the order of 10 mW m−2, decreasing with greater depths. Results indicate that site-specific heat content estimates over North America can differ by as much

  20. Strategic environments (SWOT) for nuclear energy innovation in the 21. century

    International Nuclear Information System (INIS)

    In prospecting the role of nuclear energy in a future society, it is necessary to foresee the social attitudes towards energy, economy and environment, and to analyze their interactions with the exploitation of nuclear energy itself. As those issues, this article looks upon the change of the socio-economic environment, the concerns about nuclear power and eco-environment, and the sustainability and limits of the energy resources, etc. With this perception, the so-called SWOT analysis is employed to identify the internal strengths (S) and/or weaknesses (W) of nuclear energy compared with other energy competitors on the basis of the evaluation of the external factors which are likely to play the roles of opportunities (O) for and/or threats (T) against the technological change in nuclear energy.

    Corrosion of metallic structural materials in complex gas environments of coal gasification and combustion is a potential problem. The corrosion process is dictated by concentrations of two key constituents: sulfur as H{sub 2}S or SO{sub 2} and chlorine as HCl. This paper presents a comprehensive review of the current status of the corrosion performance of alumina scales that are thermally grown on Fe-base alloys, including iron aluminides, in multicomponent gas environments of typical coal-conversion systems. Mechanisms of scale development/breakdown, performance envelopes for long-term usage of these materials, approaches to modifying the surfaces of engineering alloys by cladding or coating them with intermetallics, and in-service experience with these materials are emphasized. The results are compared with the performance of chromia-forming alloys in similar environments. The paper also discusses the available information on corrosion performance of alloys whose surfaces were enriched with Al by the electrospark deposition process or by weld overlay techniques.

    Office buildings with important administrative functions can produce high energy demands for lighting, cooling and heating. However, appropriate architectural design can achieve significant energy savings and improve environmental conditions, without sacrificing architectural quality. Intense solar radiation and high temperature swings in dry continental climates favour deep plan offices, though natural daylight requires limited depth. This paper presents a case study of a large administrative complex project for the Justice Palace, Neuquen Province, in the cold windy sem-desert climate in the Northern Patagonia Region of Argentina, demonstrating the relevance of specialised advisory services in the architectural field.

    The Center for Energy Education (CEE) is a partnership linking the University of Oklahoma, Close Up Foundation and Department of Energy. Based upon the theme of energy, environment and public policy, the CEE`s main purposes are to: (1) educate teachers on energy sources, environmental issues and decisionmaking choices regarding public policy; (2) develop interdisciplinary curricula that are interactive in nature (see attachments); (3) disseminate energy education curricula; (4) serve as a resource center for a wide variety of energy education materials; (5) provide a national support system for teachers in energy education; and (6) conduct research in energy education. The CEE conducted its first two-week experimentially-based program for educators during the summer of 1993. Beginning at the University of Oklahoma, 57 teachers from across the country examined concepts and issues related to energy and environment, and how the interdependence of energy and environment significantly influences daily life. During the second week of the institute, participants went to Washington, D.C. to examine the processes used by government officials to make critical decisions involving interrelationships among energy, environment and public policy. Similar institutes were conducted during the summers of 1994 and 1995 resulting in nearly 160 science and social studies educators who had participated in the CEE programs. Collectively the participants represented 36 states, the Pacific Territories, Puerto Rico, and Japan.

    Research at the Interface of Marine Hydrokinetic Energy and the Environment: A Workshop; Minneapolis, Minnesota, 5-7 October 2011 Marine and hydrokinetic (MHK) energy harvesting technologies convert the kinetic energy of waves and water currents into power to generate electricity. Although these technologies are in early stages of development compared to other renewable technologies, such as solar and wind energy, they offer electricity consumers situated near coastlines or inland rivers an alternative energy technology that can help meet renewable portfolio standards. However, the potential environmental impacts of MHK energy are far from well understood, both in general principles and in site-specific cases. As pressure for new MHK energy licenses builds, accelerated research in providing the scientific understanding of harnessing the natural power of water for renewable energy at a competitive cost and without harming the environment becomes a priority.

    This article rises up reflexions on the energy policy perception and formulation by the syndicate movements, as far the socio environmental aspects are concerning. In the first part conceptual reflexions are reached on the political and possible conflicts and limitation of the syndicate acting specifically those one connected to the electrical sector. The second one which is based on an investigation of syndicate documents and interviews, develops comments with base on observed syndicate behaviours, the adhesion, subordination or resistance (some elements usual of marxist analysis of the relationship capital-labor) from the syndicate movements on environmental aspects of the energy politics in force. The conclusive part reflexions are made on the possible alliances (tactical or strategic) between the syndical movements and environmental movement.

    2015-06-01

    Full Text Available The influence of a dielectric on the oscillations of the Fermi energy of nanometer metal films has been theoretically investigated. It has been shown within the model of rectangular finite-depth asymmetric potential well that the presence of a dielectric from one side of the film leads to the reduction of the maxima and displacement of the peaks on the left side of the size dependence of the Fermi energy, in contrast to the idealized case of a hypothetical film in vacuum. The calculations have been carried out for Au, Al and Cu films on SiO2 and Al2O3. This work was supported by the Ministry of Education and Science (project №04313.

  2. Perspectives in nuclear power, energy and the environment

    International Nuclear Information System (INIS)

    An experiment in informing the public on the pros and cons of nuclear power was carried out in Sweden during the autumn and winter of 1974. Study groups were arranged in collaboration with various organisations involved in adult education. The Ministry for Industry provided the background material, consisting of various official publications and a literature list, and general information. Almost 100,000 persons participated in these study circles. Neither protagonists or antagonists of nuclear power were satisfied with the material provided. A subjective conclusion is that the public opinion requires continued economic growth and increased consumption of energy, though conservation is to be strived for. There are considerable doubts regarding nuclear energy and a majority are probably opposed, but there is also opposition to dependence on imported fuel. Further hydroelectric construction would be accepted but there is scepsis regarding wind, solar and geothermal power. (JIW)

    This study analyzed the effect of carbon dioxide reduction policy generated by energy use by developing a new operation general equilibrium model. This model is a multi sector successive dynamic model, designed to be able to forecast economic variables as well as GDP, energy consumption, and carbon dioxide emission amount until 2030 for every 5 years. Using this model, it analyzed three greenhouse gas reduction policy scenarios, the introduction of world single carbon tax, the setting up limit of greenhouse gas discharge, and the introduction of international discharge permit trading system. It analyzes that it gives a heavy burden to Korean economy when Korean government implements the greenhouse gas reduction policy with only domestic policy instrument. Therefore it is considered that it is required to reduce greenhouse gas cost-effectively by using Kyoto Protocol actively, such as international permit trading, co-implementation, and clean development system, when greenhouse gas reduction gives a heavy burden. Moreover, a policy that is dependent only on price mechanism, such as carbon tax or permit trading, to reduce greenhouse gas requires a very high cost and has a limitation. Therefore, to relieve some burden on economy requires to implement non-price mechanism simultaneously such as energy technology development and restructuring on industry and transportation system.

  13. Energy and the environment: a review of the main features

    International Nuclear Information System (INIS)

    Science and technology have so far failed to discover practicable methods of tapping, on a large scale, the almost limitless supplies of energy in the form of solar radiation and its geophysical effects, the hot rocks inside the earth, and the thermonuclear potential of the hydrogen in the oceans. The problem with the natural energy sources is primarily an economic one. Despite its immense technical difficulties, thermonuclear fusion power seems a better long-term prospect. Biological methods of capturing solar energy, through photosynthesis, are not very promising. To meet this country's needs for petrol and gas from methane made from wood, about half the land area would have to be covered with coniferous forests. Fossil oil and gas supplies are unlikely to meet world needs for more than about 30 years longer. Coal supplies are much more plentiful and there is a good case for a strong technical effort on the desulphurisation of coal, to make it environmentally more acceptable, and on the conversion of coal to high-grade oil and gas. There is not enough uranium to support a world programme of thermal neutron reactors for more than about 20 years. The fast breeder reactor can overcome this problem, but the large-scale usage of these, in the next century, will aggravate the already deep anxieties about the risks to Society from radioactivity and other nuclear hazards. It is thus important to press forward strongly with programmes of fusion nuclear power, which would be more acceptable socially and environmentally. Later in the next century, the effects of man's sctivities on the world's climate may become important. It is already time to begin now to investigate these scientifically. (author)

  16. A guide to geothermal energy and the environment

    Energy Technology Data Exchange (ETDEWEB)

    Kagel, Alyssa; Bates, Diana; Gawell, Karl

    2005-04-22

    Geothermal energy, defined as heat from the Earth, is a statute-recognized renewable resource. The first U.S. geothermal power plant, opened at The Geysers in California in 1960, continues to operate successfully. The United States, as the world's largest producer of geothermal electricity, generates an average of 15 billion kilowatt hours of power per year, comparable to burning close to 25 million barrels of oil or 6 million short tons of coal per year. Geothermal has a higher capacity factor (a measure of the amount of real time during which a facility is used) than many other power sources. Unlike wind and solar resources, which are more dependent upon weather fluctuations and climate changes, geothermal resources are available 24 hours a day, 7 days a week. While the carrier medium for geothermal electricity (water) must be properly managed, the source of geothermal energy, the Earth's heat, will be available indefinitely. A geothermal resource assessment shows that nine western states together have the potential to provide over 20 percent of national electricity needs. Although geothermal power plants, concentrated in the West, provide the third largest domestic source of renewable electricity after hydropower and biomass, they currently produce less than one percent of total U.S. electricity.

    Research in the Division's environmental science program includes air pollution, water pollution, and the effects of pollutants on man and natural ecosystems. Work has focused on the chemistry and physics of particle surfaces. Using the technique of electron spectroscopy for chemical analysis (ESCA), surface reactions of sulfur and nitrogen compounds have been studied, and results include the identification of new chemical forms of nitrogen on particle surfaces and evidence for the importance of particle surfaces in the catalysis of sulfur dioxide to sulfuric acid. The Division's work in water pollution has been devoted to the study of trace metals in the estuarine environment, especially in San Francisco Bay. Studies on the effect of dredging operations on trace metals in the Mare Island ship channel and on the distribution of cadmium in Bay sediments have been performed. Research has also been conducted on the distribution of trace elements between bound states on suspended particles and in solution in Bay waters. Research is being conducted on a variety of problems relating to effects of pollutants. Biological studies seeking to discover effects of specific environmental insults such as oxidants at the cellular level have been done, and epidemiological studies have been initiated on the impacts of trace metals on human health. Theoretical studies in an attempt to develop a basis for assessing the stability of ecological systems are also being undertaken.

  18. Department of Energy LLW disposal; adapting to a changing environment

    International Nuclear Information System (INIS)

    The Department of Energy's philosophy is evolving to meet the challenge of providing safe and cost-effective LLW management. The DOE expects to use a system approach by obtaining consensus on performance requirements with all of the involved regulatory agencies and by applying these performance requirements to the best available site. Engineered features will be added either through the stabilization of the waste or site improvements as required to meet the performance requirements. Necessary waste stabilization will be incorporated into the waste acceptance criteria relieving the operator from making waste treatment decisions on a strict cost-effectiveness basis. The initial analysis to determine a configuration which meets minimum performance requirements will also serve as the baseline for additional analyses to meet the ALARA requirements

    A particle inlet system comprises a first chamber having a limiting orifice for an incoming gas stream and a micrometer controlled expansion slit. Lateral components of the momentum of the particles are substantially cancelled due to symmetry of the configuration once the laminar flow converges at the expansion slit. The particles and flow into a second chamber, which is maintained at a lower pressure than the first chamber, and then moves into a third chamber including multipole guides for electromagnetically confining the particle. The vertical momentum of the particles descending through the center of the third chamber is minimized as an upward stream of gases reduces the downward momentum of the particles. The translational kinetic energy of the particles is near-zero irrespective of the mass of the particles at an exit opening of the third chamber, which may be advantageously employed to provide enhanced mass resolution in mass spectrometry.

    Electricity is recognized to be essential to attaining even minimum modem levels of human welfare in any country. However, where electricity is available, the public shows little concern about where it comes from or what it takes to make sure supply continues to be adequate. In the next century, the world will have to face the difficult decision about the long-term use of plutonium as fuel, and deal with its implications for nonproliferation. What the United States does on this issue will affect all nations, and particularly those around the Pacific Basin. How do responsible leaders set rational priorities in a democracy, when every issue has its vocal advocates and the news media can reach every household? If democracies are to avoid the downside risks of energy shortages, leadership will have to emerge that has the courage to tell the people the truth. That means providing scientific facts and explanations in terms that people can understand.

  5. Environmental challenges and opportunities of the evolving North American electricity market : Assessing barriers and opportunities for renewable energy in North America

    International Nuclear Information System (INIS)

    A substantial contribution to the electricity supply of North America can be made by renewable energy. Its uses range from transport fuels based on biomass, to space and hot water heating in buildings and industry. Two possible options are distributed forms of renewable energy and central large-scale technology. Significant employment opportunities could be created from the manufacturing, installation and maintenance of renewable technology. In Mexico, the United States and Canada, rural economic development could be enhanced through the use of wind and biomass fuels. Every three years between 1994 and 2001, wind power installations doubled, and a comparable rate was achieved for the period 1996 to 2001 in the case of photovoltaic shipments. North America's share of this accelerating market in renewable energy sources is declining. To rectify the situation, the author indicated that several issues need to be addressed in all three countries and the trading rules in place under the North American Free Trade Agreement (NAFTA) need to be reconciled. Several recommendations were made concerning topics as varied as general policy principles to promote renewable technology, establishment of incentives for renewables, renewable electricity, biomass fuels, economic and social policies, research and development and purchasing. 30 refs

    2015-01-01

    Full Text Available The energy density governing equation to analyze the high-frequency dynamic behavior of plates in thermal environments is derived in this paper, in which the thermal effects are considered to change the membrane stress state and temperature dependent material properties of plates. Then the thermal effects on the energy reflection and transmission coefficients are dealt with hereof. Based on the above, an EFEM (energy finite element method based approximate approach for the energy analysis of coupled plates under nonuniform thermal environments is proposed. The approach could be conducted by three steps: (1 thermal analysis, (2 thermal stress analysis, and (3 forming element matrixes, joint matrixes, and the whole EFEM formulation for the energy analysis. The same mesh model is used for all the three steps. The comparison between EFEM results and classical modal superposition method results of simply supported plates in various uniform thermal environments and coupled plates in nonuniform thermal environments demonstrated that the derived energy governing equation and the proposed approach described well the smooth time- and locally space-averaged energy density. It is found that the distributions and levels of energy density are affected by thermal effects, and the variation trends are related to exciting frequency.

  8. Changes in Surface Wind Speed over North America from CMIP5 Model Projections and Implications for Wind Energy

    Directory of Open Access Journals (Sweden)

    Sujay Kulkarni

    2014-01-01

    Full Text Available The centennial trends in the surface wind speed over North America are deduced from global climate model simulations in the Climate Model Intercomparison Project—Phase 5 (CMIP5 archive. Using the 21st century simulations under the RCP 8.5 scenario of greenhouse gas emissions, 5–10 percent increases per century in the 10 m wind speed are found over Central and East-Central United States, the Californian Coast, and the South and East Coasts of the USA in winter. In summer, climate models projected decreases in the wind speed ranging from 5 to 10 percent per century over the same coastal regions. These projected changes in the surface wind speed are moderate and imply that the current estimate of wind power potential for North America based on present-day climatology will not be significantly changed by the greenhouse gas forcing in the coming decades.

  9. Leveraging Human-environment Systems in Residential Buildings for Aggregate Energy Efficiency and Sustainability

    Science.gov (United States)

    Xu, Xiaoqi

    Reducing the energy consumed in the built environment is a key objective in many sustainability initiatives. Existing energy saving methods have consisted of physical interventions to buildings and/or behavioral modifications of occupants. However, such methods may not only suffer from their own disadvantages, e.g. high cost and transient effect, but also lose aggregate energy saving potential due to the oftentimes-associated single-building-focused view and an isolated examination of occupant behaviors. This dissertation attempts to overcome the limitations of traditional energy saving research and practical approaches, and enhance residential building energy efficiency and sustainability by proposing innovative energy strategies from a holistic perspective of the aggregate human-environment systems. This holistic perspective features: (1) viewing buildings as mutual influences in the built environment, (2) leveraging both the individual and contextualized social aspects of occupant behaviors, and (3) incorporating interactions between the built environment and human behaviors. First, I integrate three interlinked components: buildings, residents, and the surrounding neighborhood, and quantify the potential energy savings to be gained from renovating buildings at the inter-building level and leveraging neighborhood-contextualized occupant social networks. Following the confirmation of both the inter-building effect among buildings and occupants' interpersonal influence on energy conservation, I extend the research further by examining the synergy that may exist at the intersection between these "engineered" building networks and "social" peer networks, focusing specifically on the additional energy saving potential that could result from interactions between the two components. Finally, I seek to reach an alignment of the human and building environment subsystems by matching the thermostat preferences of each household with the thermal conditions within their

  12. Energy-environment-development interactions. Report on working group 6

    International Nuclear Information System (INIS)

    Natural resources, including strategic resources as oil or fresh water, have been the cause of disputes and wars among nations. Natural resources have also been catalyzers of conflicts and objectives of military actions. In last decades, new potential sources of conflict have emerged, as high geographical concentration of fossil duels, acceleration of the depletion and pollution of otherwise renewable resources, and the increase of resource scarcity because of higher demands from population growth and larger consumption per capita. The potential change of climate threatens to become an important source of international tensions in the near future and to provoke the scarcity of vital resources in particular regions. If the world is to engage in a true process of sustainable development, radical changes in the present strategies and patterns of resources use are needed. This working group focused on the problems and potential solutions related to renewable energy sources. The topic of water and security were discussed as well as multilateral agreements and negotiations regarding global climate change

  14. Essays on energy, equity, and the environment in developing countries

    Science.gov (United States)

    Israel, Debra Kim

    1999-11-01

    The essays in this dissertation explore different environmental and public policy issues relevant to developing countries. Essay I examines household-level survey responses to the question "How willing would you be to pay somewhat higher taxes to the government if you knew the money would be spent to protect the environment and prevent land, water and air pollution?" Specifically, for twelve developing and three developed countries included in the survey, the empirical relationships among willingness to pay for environmental quality, relative household income and national income are investigated. The results indicate that when the effects of household and national income are combined, households with below-average income in low-income countries are less willing to pay for environmental protection than those with above-average income in high-income countries. Furthermore, willingness to pay for environmental protection increases more significantly with relative household income than with national income. Essay II uses data from urban Bolivia to study the determinants of household fuel choice, an important link between deforestation and indoor air pollution in developing countries. In particular, the effects of fixed fuel costs, income growth, and female earned income on household fuel choice are examined. The results imply that reduction in firewood use in developing countries is not likely to occur simply as the result of income growth. The essay discusses possible policy implications based on the results that fixed fuel costs appear to be a deterrent to switching to a cleaner fuel and households with female earned income seem less likely to use firewood than other households. Essay III analyzes the equity implications of the elimination of fuel subsidies in the 1985 Bolivian economic reforms. An analysis of the direct static burden shows that while the elimination of gasoline subsidies was progressively distributed, the elimination of LPG and kerosene subsidies

    A long-term variation of the inner zone high-energy proton environment at low orbits was investigated by DSTM using the adiabatic approximation of charge particle motion with NASA standard radiation models as reference states. The DST results show that over the past three decades the fluxes of high-energy protons at (1000 km in the South Atlantic Anomaly (SAA) noticeably increased, the center region of proton SAA apparently moved westward and expanded. Calculations of the L-shell averaged lifetime of high-energy protons indicate that the DST provides a reasonable means for estimation of the secular variation of inner zone proton environment.

    It is difficult to fully satisfy the energy demand of today’s society with renewables. Nevertheless, most of the energy we use is lost as non-functional waste energy, whereas a large part of the built environment’s energy demand is only for low-quality energy, so the initial demand for primary, high

  17. Competitive dynamics of energy, environment, and economy in the U.S

    International Nuclear Information System (INIS)

    This paper applies the Lotka–Volterra model to investigate the competitive interactions among energy, environment, and economy (3Es) in the U.S. The proposed LV-COMSUD (Lotka–Volterra COmpetition Model for SUstainable Development) has satisfactory performance for model fitting and provides a useful multivariate framework to predict outcomes concerning these interactions. Our key findings include a pure competition between emissions and GDP (Gross Domestic Product), neutralisms between renewable and fossil/nuclear energy, and commensalisms between GDP and renewable/fossil energy and between nuclear energy and fossil energy/emissions. These results indicate that renewable/fossil energy use contributes to GDP and interacts indirectly with emissions, that an environmental Kuznets curve exists, and that the amount of produced nuclear energy correlates with emission. The U.S. is dependent on non-clean energy sources and its energy efficiency has room for improvement. The results provide unique insights for policy makers to craft up sustainable economic development plans. Overall, it is suggested that for developed markets such as the U.S., to enhance energy security and mitigate climate changes, improving energy efficiency and developing low-carbon clean energy should be top priorities. - Highlights: • The competitive interactions among energy, environment, and economy are examined. • A pure competition between emissions and GDP exists and an EKC exists. • Energy use contributes to GDP and interacts indirectly with emissions. • Nuclear energy was used to tackle the growth of emissions/fossil energy use. • Improved energy efficiency is a viable policy to enhance energy security in U.S

    controller and to evaluate commercially available units. Research is continuing on 'passive' approaches to solar heating and cooling where careful considerations of architectural design, construction materials, and the environment are used to moderate a building's interior climate. Computer models of passive concepts are being developed in a collaborative project with Los Alamos Scientific Laboratory. These models will be incorporated into public domain building energy analysis computer programs to be used in systems studies and in the design of commercial buildings on a case study basis. The investigation of specific passive cooling methods is an ongoing project; for example, a process is being studied in which heat storage material would be cooled by radiation to the night sky, then provide 'coolness' to the building. The laboratory personnel involved in the solar cooling, controls, and passive projects are also providing technical support to the Solar Heating and Cooling Research and Development Branch of DOE in developing program plans, evaluating proposals, and making technical reviews of projects at other institutions and in industry. Low grade heat is a widespread energy resource that could make a significant contribution to energy needs if economical methods can be developed for converting it to useful work. Investigations continued this year on the feasibility of using the 'shape-memory' alloy, Nitinol, as a basis for constructing heat engines that could operate from energy sources such as solar heated water, industrial waste heat, geothermal brines, and ocean thermal gradients. Several projects are investigating longer-term possibilities for utilizing solar energy. One project involves the development of a new type of solar thermal receiver that would be placed at the focus of a central receiver system or a parabolic dish. The conversion of the concentrated sunlight to thermal energy would be accomplished by the absorption of the

    2015-12-01

    Full Text Available One of the significant ways to save energy use in buildings is to implement advanced energy retrofits in existing buildings. Improving energy performance of buildings through advanced energy retrofitting requires a clear understanding of the cost and energy implications of design alternatives from various engineering disciplines when different retrofit options are considered. The communication of retrofit design alternatives and their energy implications is essential in the decision-making process, as it affects the final retrofit selections and hence the energy efficiency of the retrofitted buildings. The objective of the research presented here was to identify a generic list of information requirements that are needed to be shared and collectively analyzed by integrated design teams during advanced energy retrofit design review meetings held in immersive settings. While identifying such requirements, the authors used an immersive environment based iterative requirements elicitation approach. The technology was used as a means to better identify the information requirements of integrated design teams to be analyzed as a group. This paper provides findings on information requirements of integrated design teams when evaluating retrofit options in immersive virtual environments. The information requirements were identified through interactions with sixteen experts in design and energy modeling domain, and validated with another group of participants consisting of six design experts who were experienced in integrated design processes. Industry practitioners can use the findings in deciding on what information to share with integrated design team members during design review meetings that utilize immersive virtual environments.

    Seasonal forest fires in the Amazon are the largest source of pollutants in South America. The impacts of aerosols due to biomass burning on the temperature and energy balance in South America are investigated using climate simulations from 1979 to 2005 using HadGEM2-ES, which includes the hot plume-rise scheme (HPR) developed by Freitas et al. (Estudos Avançados 19:167-185, 2005, Atmos Chem Phys 7:3385-3398, 2007, Atmos Chem Phys 10:585-594, 2010). The HPR scheme is used to estimate the vertical heights of biomass-burning aerosols based on the thermodynamic characteristics of the underlying model. Three experiments are performed. The first experiment includes the HPR scheme, the second experiment turns off the HPR scheme and the effects of biomass aerosols (BIOMASS OFF), and the final experiment assumes that all biomass aerosols are released at the surface (HPR OFF). Relative to the BIOMASS OFF experiment, the temperature decreased in the HPR experiment as the net shortwave radiation at the surface decreased in a region with a large amount of biomass aerosols. When comparing the HPR and HPR OFF experiments, the release of biomass aerosols higher on the atmosphere impacts on temperature and the energy budget because the aerosols were transported by strong winds in the upper atmospheric levels.

    Full Text Available Development of competitive policies and improvement of environment protection strategies are two basic trends of the development of the European Unique Market. Energy, also known as 'industry bread', is basic product and strategic resource, where energy industry plays an obvious role in the economic and social development of any community. Traditional energy production is marred by three major drawbacks: it generates negative externalities by polluting; it is totally in the hands of the producers; hence, prices rise at their will, of fossil fuels such as oil and gas. Present study focuses on electric energy industry, yet bearing over the whole length of the chain producer-to-end-consumer, thus revealed as particularly complex. The question is do alternative energy sources meet the prerequisite of market being competitive meanwhile environment protection being highly observed. We identify limits in point, of the energy market; effects of market liberalization; entry barriers; interchangeability level of energy sources; active forces on the energy market. Competitive rivalry has been expressed as per market micro-economic analysis, based on Michael Porter's 5-forces model. It will thus be noticed that, morphologically, competition evolution depends firstly on the market type. For the time being, the consumer on the energy market stays captive, for various reasons such as: legislation; limits of energy transfer infrastructure; scarcity of resources; resources availability imbalance; no integrative strategy available, of renewable energy resources usage. Energy availability is vital for human society to function. Comparative advantages of renewable energy resources are twofold, as manifested: in terms of economics, i.e. improving competition by substitute products entered at the same time as new producers enter market; and in terms of ecology, by reducing CO2 emissions. As to energy production technology and transfer, the complementary nature will

    Integrating renewable energy in the urban environment is of importance for the renewable energy goals set by the European Union. This research is to study and evaluate wind energy potential for an Integrated Roof Wind Energy System on the rooftop of the buildings of different heights and in different locations with the help of numerical modelling (CFD). The Navier-Stokes equations are solved using the SIMPLE algorithm while the turbulence is modelled using the k-ω SST equations. All the simulations are performed using OpenFOAM. Results shows that wind speed can be accelerated by ∼1.4 times till it reaches the periphery of the turbine inside the unit, which will increase wind power output considerably. This results in power factor increase of 1.7 for tall buildings. Therefore, enabling combined micro wind and solar energy systems to be a viable option for urban environments.

  11. A survey of energy policy priorities in the United States: Energy supply security, economics, and the environment

    International Nuclear Information System (INIS)

    Security, environment, and economic concerns are commonly identified as three major objectives of energy policy. State and federal governments have set aggressive targets for carbon emissions reductions and for alternative fuel use and increased vehicle efficiency to reduce petroleum consumption. Moreover, jobs creation and GDP growth are often cited as key drivers for energy policies. Previous studies on energy policy decision-making have examined the process for developing and evaluating options using multi-criteria decision analysis tools. In addition, energy opinion polls have either elicited preferences between two goals or whether the public supports a specific policy action. In this article, we report results from a survey of 884 members of professional membership organizations on how the U.S. should prioritize energy policy across the goals of energy supply security, environment and climate, and economics and job creation. The majority favor policymaking that is balanced across all three. Security and economic concerns increase with age for male respondents, whereas environment is the highest priority for females regardless of age. Unlike previous surveys that target the general public and focus on a particular objective or technology, these results provide an example of eliciting a portfolio allocation across multiple energy policy goals from targeted constituents. - Highlights: • We surveyed 884 members of professional membership organizations on how the U.S. should prioritize energy policy. • The paper addresses direct elicitation of energy policy goal portfolio allocation for a large set of energy stakeholders. • The majority of respondents favor policymaking balanced across multiple goals. • We observed differences in priorities based on age and gender. • Respondents expressed a tension in allocating across goals that are interrelated

    2015-01-01

    We explore excitonic energy transfer dynamics in a molecular dimer system coupled to both structured and unstructured oscillator environments. By extending the reaction coordinate master equation technique developed in [J. Iles-Smith, N. Lambert, and A. Nazir, Phys. Rev. A 90, 032114 (2014)], we go beyond the commonly used Born-Markov approximations to incorporate system-environment correlations and the resultant non-Markovian dynamical effects. We obtain energy transfer dynamics for both underdamped and overdamped oscillator environments that are in perfect agreement with the numerical hierarchical equations of motion over a wide range of parameters. Furthermore, we show that the Zusman equations, which may be obtained in a semiclassical limit of the reaction coordinate model, are often incapable of describing the correct dynamical behaviour. This demonstrates the necessity of properly accounting for quantum correlations generated between the system and its environment when the Born-Markov approximations no ...

  13. Environment-adjusted total-factor energy efficiency of Taiwan's service sectors

    International Nuclear Information System (INIS)

    This study computes the pure technical efficiency (PTE) and energy-saving target of Taiwan's service sectors during 2001–2008 by using the input-oriented data envelopment analysis (DEA) approach with the assumption of a variable returns-to-scale (VRS) situation. This paper further investigates the effects of industry characteristics on the energy-saving target by applying the four-stage DEA proposed by Fried et al. (1999). We also calculate the pre-adjusted and environment-adjusted total-factor energy efficiency (TFEE) scores in these service sectors. There are three inputs (labor, capital stock, and energy consumption) and a single output (real GDP) in the DEA model. The most energy efficient service sector is finance, insurance and real estate, which has an average TFEE of 0.994 and an environment-adjusted TFEE (EATFEE) of 0.807. The study utilizes the panel-data, random-effects Tobit regression model with the energy-saving target (EST) as the dependent variable. Those service industries with a larger GDP output have greater excess use of energy. The capital–labor ratio has a significantly positive effect while the time trend variable has a significantly negative impact on the EST, suggesting that future new capital investment should also be accompanied with energy-saving technology in the service sectors. - Highlights: • The technical efficiency and energy-saving target of service sectors are assessed. • The pre-adjusted and environment-adjusted total-factor energy efficiency scores in services are assessed. • The industrial characteristic differences are examined by the panel-data, random-effects Tobit regression model. • Labor, capital, and energy and an output (GDP) are included in the DEA model. • Future new capital investment should also be accompanied with energy-saving technology in the service sectors

    With the successful experience on energy efficiency in the past 30 years in China, it can be summarized as Energy Usage Management(EUM) and Integrated Resource Strategic Planning(IRSP). They will play essential role in Low Carbon Economy. The model of Low Carbon Economy-Energy-Electricity-Environment and an outlook of Chinese economic growth, energy-electricity demand, and renewable energy generation have been studied in this paper. It has been shown that China would save energy 4.38 billion toe and reduce CO2 emission 16.55 billion ton by EUM, and would save energy 1.5 billion toe and reduce CO2 emission 5.7 Btons by IRSP during 2010-2030.

  17. Photosynthetic Energy Storage for the Built Environment: Modeling Energy Generation and Storage for Net-Zero Analysis

    Science.gov (United States)

    Lichter-Marck, Eli Morris

    There is a growing need to address the energy demand of the building sector with non-polluting, renewable energy sources. The Net Zero Energy Building (NZEB) mandate seeks to reduce the impact of building sector energy consumption by encouraging on-site energy generation as a way to offset building loads. However, current approaches to designing on-site generation fail to adequately match the fluctuating load schedules of the built environment. As a result, buildings produce highly variable and often-unpredictable energy import/export patterns that create stress on energy grids and increase building dependence on primary energy resources. This research investigates the potential of integrating emerging photo-electrochemical (PEC) technologies into on-site generation systems as a way to enable buildings to take a more active role in collecting, storing and deploying energy resources according to their own demand schedules. These artificially photosynthetic systems have the potential to significantly reduce variability in hour-to-hour and day-to-day building loads by introducing high-capacity solar-hydrogen into the built environment context. The Building Integrated Artificial Photosynthesis (BIAP) simulation framework presented here tests the impact of hydrogen based energy storage on NZEB performance metrics with the goal of developing a methodology that makes on-site energy generation more effective at alleviating excessive energy consumption in the building sector. In addition, as a design performance framework, the BIAP framework helps guide how material selection and scale up of device design might tie photo-electrochemical devices into parallel building systems to take full advantage of the potential outputs of photosynthetic building systems.

This demonstrates the necessity of properly accounting for quantum correlations generated between the system and its environment when the Born-Markov approximations no longer hold. Finally, we apply the reaction coordinate formalism to the case of a structured environment comprising of both underdamped (i.e., sharply peaked) and overdamped (broad) components simultaneously. We find that though an enhancement of the dimer energy transfer rate can be obtained when compared to an unstructured environment, its magnitude is rather sensitive to both the dimer-peak resonance conditions and the relative strengths of the underdamped and overdamped contributions.

    The effects of midenergy electrons on the charge and discharge characteristics of spacecraft dielectric materials and the data base from which basic discharge models can be formulated is expanded. Thin dielectric materials were exposed to low, mid combined low and mid, and spectral energy electron environments. Three important results are presented: (1) it determined electron environments that lead to dielectric discharges at potentials less negative than -5 kV; (2) two types of discharges were identified that dominate the kinds of discharges seen; and (3) it is shown that, for the thin dielectric materials tested, the worst-case discharges observed in the various environments are similar.

  1. Role of nuclear fusion in future energy systems and the environment under future uncertainties

    International Nuclear Information System (INIS)

    Debates about whether or not to invest heavily in nuclear fusion as a future innovative energy option have been made within the context of energy technology development strategies. This is because the prospects for nuclear fusion are quite uncertain and the investments therefore carry the risk of quite large regrets, even though investment is needed in order to develop the technology. The timeframe by which nuclear fusion could become competitive in the energy market has not been adequately studied, nor has roles of the nuclear fusion in energy systems and the environment. The present study has two objectives. One is to reveal the conditions under which nuclear fusion could be introduced economically (hereafter, we refer to such introductory conditions as breakeven prices) in future energy systems. The other objective is to evaluate the future roles of nuclear fusion in energy systems and in the environment. Here we identify three roles that nuclear fusion will take on when breakeven prices are achieved: (i) a portion of the electricity market in 2100, (ii) reduction of annual global total energy systems cost, and (iii) mitigation of carbon tax (shadow price of carbon) under CO2 constraints. Future uncertainties are key issues in evaluating nuclear fusion. Here we treated the following uncertainties: energy demand scenarios, introduction timeframe for nuclear fusion, capacity projections of nuclear fusion, CO2 target in 2100, capacity utilization ratio of options in energy/environment technologies, and utility discount rates. From our investigations, we conclude that the presently designed nuclear fusion reactors may be ready for economical introduction into energy systems beginning around 2050-2060, and we can confirm that the favorable introduction of the reactors would reduce both the annual energy systems cost and the carbon tax (the shadow price of carbon) under a CO2 concentration constraint

    The Environmental Law and Policy Center of Illinois has recently released several publications promoting clean energy development to improve environmental quality and public health for the Midwest. This presentation emphasized how the clean energy development plan can create new jobs and stimulate economic growth. For example, the electric power industry is currently relying on 1950's energy technology. Modernizing the electricity industry would be good for both the economy and the environment. Repowering the industry would promote energy efficiency and renewable energy sources. The presentation also compared a business-as-usual (BAU) scenario and a clean energy development plan scenario for 2010 and 2020. It was suggested that policy changes may be required to ensure change. In the BAU scenario, electricity demand would increase annually, large additions of natural gas capacity would be used to meet the demand, and coal plants would increase their output. Under the clean energy development plan, electricity demand would flatten out, coal and nuclear plants would be replaced with renewables (mostly wind) or clean, natural gas generation. Under the clean energy development plan NOx would be reduced by 71 per cent, SOx by 56 per cent, mercury by 50 per cent, and carbon dioxide by 51 per cent. The clean energy development plan improves the environment by reducing air and water pollution and improves electricity reliability. 8 tabs., 20 figs.

  4. A universal, broad-environment energy conversion signature of explosive cyclones

    2013-01-01

    This study presents the first analysis of the Lorenz energetics associated with a global climatology of explosive cyclones. Energy budgets of the large-scale environment are calculated for 32 year climatologies (1980-2011) of explosive cyclones within four of the most active regions in the world: the Northwest Pacific, the North Atlantic, the Southwest Pacific, and the South Atlantic. A robust signature in the Lorenz energy cycle is observed; anomalous energy conversions commence 48 h before explosive cyclone development and remain strong (i.e., significantly above background noise) for 120 h. Remarkably, the calculated signature of energy conversion is virtually identical for all four geographical regions. While the conversions imply a classic baroclinic growth cycle, they are not seen in regular cyclones that undergo a deepening of less than half that exhibited by explosive cyclones. This finding opens a new avenue of exploration of explosive storm behavior based on the large-scale environment.

    Multiday ultra-endurance races present athletes with a significant number of physiological and psychological challenges. We examined emotions, the perceived functionality (optimal-dysfunctional) of emotions, strategies to regulate emotions, sleep quality, and energy intake-expenditure in a four-man team participating in the Race Across AMerica (RAAM); a 4856km continuous cycle race. Cyclists reported experiencing an optimal emotional state for less than 50% of total competition, with emotional states differing significantly between each cyclist over time. Coupled with this emotional disturbance, each cyclist experienced progressively worsening sleep deprivation and daily negative energy balances throughout the RAAM. Cyclists managed less than one hour of continuous sleep per sleep episode, high sleep latency and high percentage moving time. Of note, actual sleep and sleep efficiency were better maintained during longer rest periods, highlighting the importance of a race strategy that seeks to optimise the balance between average cycling velocity and sleep time. Our data suggests that future RAAM cyclists and crew should: 1) identify beliefs on the perceived functionality of emotions in relation to best (functional-optimal) and worst (dysfunctional) performance as the starting point to intervention work; 2) create a plan for support sufficient sleep and recovery; 3) create nutritional strategies that maintain energy intake and thus reduce energy deficits; and 4) prepare for the deleterious effects of sleep deprivation so that they are able to appropriately respond to unexpected stressors and foster functional working interpersonal relationships. Key Points Completing the Race Across AMerica (RAAM); a 4856km continuous cycle race associated with sleep disturbance, an energy-deficient state, and experiencing intense unwanted emotions. Cyclists reported experiencing an optimal emotional state for less than 50% of total competition and actual sleep and sleep efficiency

    In Costa Rica the 1300 hectares of rainforest that comprise La Selva Biological Station support more than 1.5 times the number of plant and animal species found in California. In Central America over 2/3 of all deforestation has occurred since 1950, and closed canopy forest has shrunk dramatically during the past 40 years. The population in Central America, plus Mexico, grew by around 28% during the period 1977-87. At the same time the surface of forests and woodlands decreased by 13%, to 26% of the total land area. Croplands grew by 4% during these 10 years, to 13% of the total land area, and pastures by 2% to 37%; and unproductive lands grew by 14% to 24% of total land area. 50% of land is seriously eroded or degraded in El Salvador and over 30% in Guatemala. Central America's population was 22 million in 1980, 29 million in 1990, and it is anticipated to reach 63 million by 2025. Central America's urban population reached 46% in the 1990s: over 13 million with continuing increases in the next few decades. The growing population's need for fuelwood and the demand for agricultural land pose the main threat to forests in the coming decades. Close to 90% of the energy used by households comes from fuelwood. In the Telire reserve in Costa Rica 366 Cabecars are not yet an environmental threat for the forest. The Peten area in Guatemala is inhabited by around 300,000 people whose destructive slash and burn practices pose a serious threat to the environment which is exacerbated by a high population growth rate of 5.5% a year.

  12. Morality, energy, and the environment. [Causal interrelation of energy and social crises

    Energy Technology Data Exchange (ETDEWEB)

    Sayre, K.

    Our crises of energy and of social values are causally interrelated. Our energy problems have contributed substantially to our contemporary value problems, as evident, for example, by the institution of the private automobiles, which has begun to erode the very values it initially served. That our energy crisis has resulted from problems of value is illustrated by setting up a simple model of producer-consumer interaction, with egoism and hedonism as dominant principles of duty and of good, respectively, and by showing that an energy crisis like the one we are currently experiencing is practically inevitable. These discussions lead to an assessment of the possible roles moral philosophy might play in confronting these two crises by replacing energy hedonism with a low-energy life style.

  13. Relationship between wave energy and free energy from pickup ions in the Comet Halley environment

    Science.gov (United States)

    Huddleston, D. E.; Johnstone, A. D.

    1992-01-01

    The free energy available from the implanted heavy ion population at Comet Halley is calculated by assuming that the initial unstable velocity space ring distribution of the ions evolves toward a bispherical shell. Ultimately this free energy adds to the turbulence in the solar wind. Upstream and downstream free energies are obtained separately for the conditions observed along the Giotto spacecraft trajectory. The results indicate that the waves are mostly upstream propagating in the solar wind frame. The total free energy density always exceeds the measured wave energy density because, as expected in the nonlinear process of ion scattering, the available energy is not all immediately released. An estimate of the amount which has been released can be obtained from the measured oxygen ion distributions and again it exceeds that observed. The theoretical analysis is extended to calculate the k spectrum of the cometary-ion-generated turbulence.

    Contemporary human activities such as tropical deforestation, land clearing for agriculture, pest control and grassland management lead to biomass burning, which in turn leads to land-cover changes. However, biomass burning emissions are not correctly measured and the methods to assess these emissions form a part of current research area. The traditional methods for estimating aerosols and trace gases released into the atmosphere generally use emission factors associated with fuel loading and moisture characteristics and other parameters that are hard to estimate in near real-time applications. In this paper, fire radiative power (FRP) products were extracted from Moderate Resolution Imaging Spectroradiometer (MODIS) and from the Geostationary Operational Environmental Satellites (GOES) fire products and new South America generic biomes FRE-based smoke aerosol emission coefficients were derived and applied in 2002 South America fire season. The inventory estimated by MODIS and GOES FRP measurements were included in Coupled Aerosol-Tracer Transport model coupled to the Brazilian developments on the Regional Atmospheric Modeling System (CATT-BRAMS) and evaluated with ground truth collected in Large Scale Biosphere-Atmosphere Smoke, Aerosols, Clouds, rainfall, and Climate (SMOCC) and Radiation, Cloud, and Climate Interactions (RaCCI). Although the linear regression showed that GOES FRP overestimates MODIS FRP observations, the use of a common external parameter such as MODIS aerosol optical depth product could minimize the difference between sensors. The relationship between the PM 2.5μm (Particulate Matter with diameter less than 2.5 μm) and CO (Carbon Monoxide) model shows a good agreement with SMOCC/RaCCI data in the general pattern of temporal evolution. The results showed high correlations, with values between 0.80 and 0.95 (significant at 0.5 level by student t test), for the CATT-BRAMS simulations with PM 2.5μm and CO.

    Full Text Available The main objective of the present work was to assess and compare the wave power resources in various offshore and nearshore areas. From this perspective, three different groups of coastal environments were considered: the western Iberian nearshore, islands and an enclosed environment with sea waves, respectively. Some of the most representative existent wave converters were evaluated in the analysis and a second objective was to compare their performances at the considered locations, and in this way to determine which is better suited for potential commercial exploitation. In order to estimate the electric power production expected in a certain location, the bivariate distributions of the occurrences corresponding to the sea states, defined by the significant wave height and the energy period, were constructed in each coastal area. The wave data were provided by hindcast studies performed with numerical wave models or based on measurements. The transformation efficiency of the wave energy into electricity is evaluated via the load factor and also through the capture width, defined as the ratio between the electric power estimated to be produced by each specific wave energy converters (WEC and the expected wave power corresponding to the location considered. Finally, by evaluating these two different indicators, comparisons of the performances of three WEC types (Aqua Buoy, Pelamis and Wave Dragon in the three different groups of coastal environments considered have been also carried out. The work provides valuable information related to the effectiveness of various technologies for the wave energy extraction that would operate in different coastal environments.

    Planning initiatives in many regions and communities aim to reduce transportation energy use, decrease emissions, and achieve related environmental benefits by changing land use. This report reviews and summarizes findings from existing literature on the relationship between the built environment and transportation energy use and greenhouse gas emissions, identifying results trends as well as potential future actions. The indirect influence of federal transportation and housing policies, as well as the direct impact of municipal regulation on land use are examined for their effect on transportation patterns and energy use. Special attention is given to the 'four D' factors of density, diversity, design and accessibility. The report concludes that policy-driven changes to the built environment could reduce transportation energy and GHG emissions from less than 1% to as much as 10% by 2050, the equivalent of 16%-18% of present-day urban light-duty-vehicle travel. This is one of a series of reports produced as a result of the Transportation Energy Futures (TEF) project, a Department of Energy-sponsored multi-agency project initiated to pinpoint underexplored strategies for abating GHGs and reducing petroleum dependence related to transportation.

    Directory of Open Access Journals (Sweden)

    Ian M. Lahart

    2013-09-01

    Full Text Available Multiday ultra-endurance races present athletes with a significant number of physiological and psychological challenges. We examined emotions, the perceived functionality (optimal-dysfunctional of emotions, strategies to regulate emotions, sleep quality, and energy intake-expenditure in a four-man team participating in the Race Across AMerica (RAAM; a 4856km continuous cycle race. Cyclists reported experiencing an optimal emotional state for less than 50% of total competition, with emotional states differing significantly between each cyclist over time. Coupled with this emotional disturbance, each cyclist experienced progressively worsening sleep deprivation and daily negative energy balances throughout the RAAM. Cyclists managed less than one hour of continuous sleep per sleep episode, high sleep latency and high percentage moving time. Of note, actual sleep and sleep efficiency were better maintained during longer rest periods, highlighting the importance of a race strategy that seeks to optimise the balance between average cycling velocity and sleep time. Our data suggests that future RAAM cyclists and crew should: 1 identify beliefs on the perceived functionality of emotions in relation to best (functional-optimal and worst (dysfunctional performance as the starting point to intervention work; 2 create a plan for support sufficient sleep and recovery; 3 create nutritional strategies that maintain energy intake and thus reduce energy deficits; and 4 prepare for the deleterious effects of sleep deprivation so that they are able to appropriately respond to unexpected stressors and foster functional working interpersonal relationships

    Robust speech detection in nolsy environment is an important front-end of speech processing such as speech recognition,speech enhancement and speech coding.Parameters frequently used for speech detection,such as the energy in time domain and the zero-crossing rate,exploit the properties of speech alone.Thus they show poor robustness to background noise.Speech detection in noisy environment should exploit the parameter with wihich speech and noise have maximum classification.In this paper,we propose a robust speech detection algorithm with heteroscedasitc discriminate analysis(HDA)applied to the time-frequency energy yector(TFEV).The TFEV consists of the log energy in time domain,the log energy in the fixed hand 250-3500 Hz.and the log Mel-scale frequency bands energy.Moreover,the bottom-up algorithm with automatic threshold adjustment is used for accurate word boundary detection.Compared to the algorithms based on the energy in time domain,the ATF parameter,the energy and the LDA-MFCC parameter,the proposed algorithm shows better performance under different types of noise.

  13. The Investment Environment for Renewable Energy Development in Lithuania: The Electricity Sector

    2014-06-01

    Full Text Available The article analyzes the investment environment in renewable electricity generation capacities, evaluating the credibility of long term renewable energy targets, the stability of promotion schemes and the impartiality of national administrative procedure. The article explores two main questions: (i are the EU and Lithuanian energy policy targets and promotion schemes credible enough to convince private investors to put their money in renewable energy development; (ii does national administrative procedure put a disproportional burden on renewable energy investors or on certain group of investors? The assessment of the investment environment includes a large number of criteria, but we analyze three of them: the stability of long term strategy; the attractiveness of promotionmeasures; and the simplicity and transparency of administrative procedure. Two further criteria are investigated: the stability of targets in renewable energy and the stability of promotional measures. The greatest uncertainty for investors occurs because of constantly changing support schemes of renewable energy sources-schemes that are not harmonized among the member States. At the national level the main driver in the development of small generators is the feed-in tariff. However, the high feed-in tariff does not always guarantee the smooth development of small scale generators of renewable energy.

    Full Text Available IT service providers, employ server virtualization as a main building block to improve system utilization, improve system manageability, reduce operational costs which includes energy consumption driving economies of scale with shared resources. Virtualization enables co-locating and efficient assignments of virtual servers within the bounds of limited number of heterogeneous physical servers, with Virtual Machines (VM sharing the limited physical server resources between them. Though virtualization technologies point to the fact that each virtual server has its very own isolated environment, but in reality, perfect isolation is not possible. Primary measure to achieve assignment efficiency is to ensure that system resources are utilized effectively and performance of VM (and application workloads is consistent within the desired bounds. Interference or contention on the limited shared resources among VMs leads to performance degradation and is referred to as performance interference. This affects (a application Quality of Service (QOS and (b server cluster or data centers’ energy-efficiency. In this work, we analyze the performance degradation using (a energy efficiency heterogeneity measure and (b interference aware measure, with the aim to reduce energy consumption in our environment. Experimental results on different scenarios with our energy efficiency and interference aware approach shows a reduction in energy consumption to the tune of 8 to 58% and 10× improvement in per request average response time in contrast to a default energy efficiency and interference oblivious approach.

  18. Analysis of Japan's energy and environment strategy after the Fukushima nuclear plant accident

    International Nuclear Information System (INIS)

    This paper examines economic analyses of the “Options for Energy and the Environment” proposed by the Japanese government. The main focuses of the analyses are the power generation mix in 2030, and particularly electricity supply shares of nuclear power. The options proposed by the government assume drastic energy efficiency improvements, increase in renewable energy, and deep CO2 emission reductions. Considerable energy savings are assumed by the government even in the baseline scenario, and these are inconsistent with historical growth trends for GDP and power demand. We modify the energy savings baseline scenario for consistency with the historical trends and historical electricity savings after the nuclear power accident. In order to provide a wider array of options, particularly those with fewer negative impacts on GDP, this paper proposes alternative options under a revised baseline. In the alternative options, we assume lower shares of renewable energy in electricity supply and lower carbon price. The economic impacts for the alternative options are much smaller than those assumed by the government. The economic analyses provided in this paper will help future policy making for energy and environment in Japan. - Highlights: • This paper provides economic analyses on future energy scenarios proposed by the Japanese government. • Energy savings of the government's scenarios are inconsistent with historical trends. • We modify baseline scenario of energy savings and propose alternative options. • Economic impacts for alternative options are smaller than those by the government

    2014-04-01

    In the absence of carbon sequestration, mitigating carbon emissions can be achieved through a mix of two broad policy approaches: (i) reducing energy intensity by improving energy efficiency and conservation, and (ii) changing the fuel mix. This paper investigates the long-run relationship between energy intensity, the energy mix, and per capita carbon emissions; while controlling for the level of economic activity, the economic structure measured by the relative size of the manufacturing sector, and the differences in institutional qualities across countries. We aim to answer two particularly important policy questions. First, to what extent these policy approaches are effective in mitigating emissions in the long-run? Second, which institutional qualities significantly contribute to better long-run environmental performance? We use historical data for 131 countries in a heterogeneous panel framework for the period 1972-2010. We find that less dependence on fossil fuel and lower energy intensity reduce emissions in the long run. A goal of 10% reduction in CO2 levels in the long-run requires reducing the share of fossil fuel in total energy use by 11%, or reducing energy intensity by 13%. In addition, specific institutional qualities such as better corruption control and judiciary independence contribute to mitigating levels of emissions. PMID:24568940

    2015-01-01

    Non-Markovian effects in the evolution of open quantum systems have recently attracted widespread interest, particularly in the context of assessing the efficiency of energy and charge transfer in nanoscale biomolecular networks and quantum technologies. With the aid of many-body simulation methods, we uncover and analyse an ultrafast environmental process that causes energy relaxation in the reduced system to depend explicitly on the phase relation of the initial state preparation. Remarkably, for particular phases and system parameters, the net energy flow is uphill, transiently violating the principle of detailed balance, and implying that energy is spontaneously taken up from the environment. A theoretical analysis reveals that non-secular contributions, significant only within the environmental correlation time, underlie this effect. This suggests that environmental energy harvesting will be observable across a wide range of coupled quantum systems.

    2012-06-15

    Ambitious international efforts to combat climate change have lead to a large interest about the use of forest biomass for energy in many countries. In order to meet the expected growing demand in the future, it will be necessary to improve operational efficiency of existing forest energy supply chains and support the establishment of efficient supply chains in new operational environments. The thesis applied a three-dimensional approach which examines forest energy supply chains from a technical, social and economic viewpoint. Four case studies in different operational environments have been carried out to investigate the applicability of the three dimensional approach to improve operational efficiency. The technical dimension was investigated in Paper 1 and 2. In Paper 1, the effects of climatic conditions, covering of piles, and partial debarking on drying of roundwood were studied in four experimental trials located in Scotland, Finland and Italy. In Paper 2, the chipping of forest biomass was studied in two different operational environments. The investigation of the social dimension in Paper 3 provides insights into the setup of two different supply chains through business process mapping and simulation. Finally, in paper 4, which investigated the economic dimension, an analysis of the effect of the operational environment on technology selection and design of supply chains, is presented. The thesis demonstrates that the chosen approach was practical to investigate the complex relationships between the chosen technologies and different supply chain actors and stakeholders thereby contributing to maintain or improve operational efficiency of forest energy supply chains. Due to its applicability in different operational environments, the approach is also suitable in a more global context. Furthermore, it captures the effect of different aspects and characteristics of the various operational environments on the setup and organization of supply chains. This will

  5. Thermal stability and energy harvesting characteristics of Au nanorods: harsh environment chemical sensing

    2015-05-01

    Monitoring the levels of polluting gases such as CO and NOx from high temperature (500°C and higher) combustion environments requires materials with high thermal stability and resilience that can withstand harsh oxidizing and reducing environments. Au nanorods (AuNRs) have shown potential in plasmonic gas sensing due to their catalytic activity, high oxidation stability, and absorbance sensitivity to changes in the surrounding environment. By using electron beam lithography, AuNR geometries can be patterned with tight control of the rod dimensions and spacings, allowing tunability of their optical properties. Methods such as NR encapsulation within an yttria-stabilized zirconia overcoat layer with subsequent annealing procedures will be shown to improve temperature stability within a simulated harsh environment. Since light sources and spectrometers are typically required to obtain optical measurements, integration is a major barrier for harsh environment sensing. Plasmonic sensing results will be presented where thermal energy is harvested by the AuNRs, which replaces the need for an external incident light source. Results from gas sensing experiments that utilize thermal energy harvesting are in good agreement with experiments which use an external incident light source. Principal component analysis results demonstrate that by selecting the most "active" wavelengths in a plasmonic band, the wavelength space can be reduced from hundreds of monitored wavelengths to just four, without loss of information about selectivity of the AuNRs. By combining thermal stability, the thermal energy harvesting capability, and the selectivity in gas detection (achieved through multivariate analysis), integration of plasmonic sensors into combustion environments can be greatly simplified.

  6. Towards a high resolution, integrated hydrology model of North America: Diagnosis of feedbacks between groundwater and land energy fluxes at continental scales.

    2016-04-01

    Recent studies demonstrate feedbacks between groundwater dynamics, overland flow, land surface and vegetation processes, and atmospheric boundary layer development that significantly affect local and regional climate across a range of climatic conditions. Furthermore, the type and distribution of vegetation cover alters land-atmosphere water and energy fluxes, as well as runoff generation and overland flow processes. These interactions can result in significant feedbacks on local and regional climate. In mountainous regions, recent research has shown that spatial and temporal variability in annual evapotranspiration, and thus water budgets, is strongly dependent on lateral groundwater flow; however, the full effects of these feedbacks across varied terrain (e.g. from plains to mountains) are not well understood. Here, we present a high-resolution, integrated hydrology model that covers much of continental North America and encompasses the Mississippi and Colorado watersheds. The model is run in a fully-transient manner at hourly temporal resolution incorporating fully-coupled land energy states and fluxes with integrated surface and subsurface hydrology. Connections are seen between hydrologic variables (such as water table depth) and land energy fluxes (such as latent heat) and spatial and temporal scaling is shown to span many orders of magnitude. Model results suggest that partitioning of plant transpiration to bare soil evaporation is a function of water table depth and later groundwater flow. Using these transient simulations as a proof of concept, we present a vision for future integrated simulation capabilities.

The mutual polarization between the chromophore and its surroundings is included in the PE-TD-DFT approach through the use of induced dipoles, placed on all atoms in the classical region, and self-consistent optimization of the quantum and classical polarizable regions...... of polarization interactions for chromophores in different chemical environments. We find that the rate of convergence of excitation energies with respect to polarization cut-off is much slower for chromophores in an ordered environment such as a protein than for chromophores in a homogeneous medium...

    Full Text Available Unlike what happens in Western capitalist societies, who think the world so disruptive, creating dichotomies as culture / nature and society / environment, indigenous thought in such oppositions are not common. Thus, indigenous peoples do not live a crisis mentality on the environment. The Javaé provides elements with which it becomes possible to think about their "ideas" of body and vital energy and how these inform their practices and their relationship with social and environmental. Understanding this concept as something that includes a social totality that includes humans and nonhumans, and thus, maintaining a social and ecological balance.

  9. Glycolytic Coupling to Mitochondrial Energy Production Ensures Survival in an Oxygen Rich Environment

    The mitochondrion exhibits biochemical and functional variations that emerged by random chance as an evolutionary survival strategy, which include enhanced energy production driven by anaerobic respiratory mechanisms. In invertebrates, this mitochondrial anaerobic respiration permits survival at a lower energy state suited for this type of environment while yielding more ATP than by glycolysis alone. This ability provides a protective existential advantage in naturally occurring hypoxic environments via diminished free radical generation. In the blue mussel Mytilus edulis and other marine organisms, a functionally active mitochondrial anaerobic respiratory mechanism tailored to hypoxic conditions reflects an evolutionary adaptation/reworking of ancient metabolic pathways. Components of these pathways were also discovered and characterized as metabolic intermediates in plant parasites, specifically crown gall tumors. Mechanistic similarities between anaerobically functioning mitochondria in M. edulis and crown gall tissues and metabolic processes in human tumors are known to occur, demonstrating commonalities in diverse life energy processes. Furthermore, cytoplasmic glycolytic processes are now shown also to exhibit a dynamic capacity for enhanced energy generation by increasing its efficiency in hypoxic environments, making it equally dynamic in meeting its cellular survival goal.

    Full Text Available This paper deals with issues of strategic management, particularly strategic planning of energy costs and their effect on the overall performance of businesses. It is based on empirical results of the original research survey Enterprise Surveys data for Republic of Kosova,. performed via questionnaire surveys by the World Bank in three rounds during years 2005, 2009 and 2013. The analyses presented in the paper were conducted on the third round sample of  organizations operating mostly in the SME sector in the Republic of Kosova.Among typical obstacles to the economic environment we found also the energy problem, specifically the power outages that increase further the costs of power supply for SME’s.  These phenomena not only create a state of turmoil and turbulence in the competitive environment and generate changes in market conditions, but require changes and development in organizations. In these circumstances organizations are forced to adapt costly solutions, like generators or other tools to guarantee  the customer satisfaction.Therefore to achieve any competitive advantage, organizations must take in consideration the current economic environment.The interdependence between the level of energy costs and enterprise performance criteria is examined with the use of some hypotheses. The results are commented and discussed.Keywords: energy costs, business strategy, performance criteria, questionnaire research,   

  11. Human Behavior & Low Energy Architecture: Linking Environmental Adaptation, Personal Comfort, & Energy Use in the Built Environment

    Science.gov (United States)

    Langevin, Jared

    Truly sustainable buildings serve to enrich the daily sensory experience of their human inhabitants while consuming the least amount of energy possible; yet, building occupants and their environmentally adaptive behaviors remain a poorly characterized variable in even the most "green" building design and operation approaches. This deficiency has been linked to gaps between predicted and actual energy use, as well as to eventual problems with occupant discomfort, productivity losses, and health issues. Going forward, better tools are needed for considering the human-building interaction as a key part of energy efficiency strategies that promote good Indoor Environmental Quality (IEQ) in buildings. This dissertation presents the development and implementation of a Human and Building Interaction Toolkit (HABIT), a framework for the integrated simulation of office occupants' thermally adaptive behaviors, IEQ, and building energy use as part of sustainable building design and operation. Development of HABIT begins with an effort to devise more reliable methods for predicting individual occupants' thermal comfort, considered the driving force behind the behaviors of focus for this project. A long-term field study of thermal comfort and behavior is then presented, and the data it generates are used to develop and validate an agent-based behavior simulation model. Key aspects of the agent-based behavior model are described, and its predictive abilities are shown to compare favorably to those of multiple other behavior modeling options. Finally, the agent-based behavior model is linked with whole building energy simulation in EnergyPlus, forming the full HABIT program. The program is used to evaluate the energy and IEQ impacts of several occupant behavior scenarios in the simulation of a case study office building for the Philadelphia climate. Results indicate that more efficient local heating/cooling options may be paired with wider set point ranges to yield up to 24

  13. North America and Asia Pacific LNG markets

    International Nuclear Information System (INIS)

    The liquefied natural gas (LNG) export opportunities in the Asia Pacific market were reviewed. Some of the differences that affect a North American LNG projects compared to more typical LNG projects were also outlined. The two main aspects of the LNG market in North America include the establishment of LNG import terminals on the east and southern coasts of the United States and the development of export oriented LNG projects. The Pac-Rim LNG project calls for initial delivery to South Korea of 4.0 MTPA by the end of 2000. A large LNG project has also been proposed for the year 2005 which would use Prudhoe Bay gas. Generally, in North America, there is little use for large scale LNG import projects because of the vast pipeline network that delivers gas reliably and at low cost anywhere in North America. However, LNG remains a good alternative for the Asia Pacific region because of the lack of a pipeline network. Also, Japan, Korea and Taiwan, the three main centers for LNG demand, have no domestic energy supplies and rely on imported energy sources. China is another major market opportunity for LNG. The Pac-Rim LNG project differs from others of its kind in that usually, an LNG project is based on the availability of large reservoirs of natural gas owned by state governments and involves production agreements with multi-national oil and gas companies. This scenario is simply not possible in Canada's deregulated environment. In contrast, the existence of upstream facilities, technical expertise, and low capital costs, hence reduced risks and time to develop an LNG project, gives Canada significant advantages. 3 tabs., 3 figs

  14. Analysis of the interrelationship of energy, economy, and environment: A model of a sustainable energy future for Korea

    Science.gov (United States)

    Boo, Kyung-Jin

    The primary purpose of this dissertation is to provide the groundwork for a sustainable energy future in Korea. For this purpose, a conceptual framework of sustainable energy development was developed to provide a deeper understanding of interrelationships between energy, the economy, and the environment (E 3). Based on this theoretical work, an empirical simulation model was developed to investigate the ways in which E3 interact. This dissertation attempts to develop a unified concept of sustainable energy development by surveying multiple efforts to integrate various definitions of sustainability. Sustainable energy development should be built on the basis of three principles: ecological carrying capacity, economic efficiency, and socio-political equity. Ecological carrying capacity delineates the earth's resource constraints as well as its ability to assimilate wastes. Socio-political equity implies an equitable distribution of the benefits and costs of energy consumption and an equitable distribution of environmental burdens. Economic efficiency dictates efficient allocation of scarce resources. The simulation model is composed of three modules: an energy module, an environmental module and an economic module. Because the model is grounded on economic structural behaviorism, the dynamic nature of the current economy is effectively depicted and simulated through manipulating exogenous policy variables. This macro-economic model is used to simulate six major policy intervention scenarios. Major findings from these policy simulations were: (1) carbon taxes are the most effective means of reducing air-pollutant emissions; (2) sustainable energy development can be achieved through reinvestment of carbon taxes into energy efficiency and renewable energy programs; and (3) carbon taxes would increase a nation's welfare if reinvested in relevant areas. The policy simulation model, because it is based on neoclassical economics, has limitations such that it cannot fully

  15. Energy and the environment: A sensible, no regrets'' proposal

    Energy Technology Data Exchange (ETDEWEB)

    Adler, J.H. (Competitive Enterprise Inst., Washington, DC (United States))

    America, it seems, uses too much energy. Thus, the government prepares to issue a new round of federal energy efficiency standards for all manner of household appliances. The Sierra Club insists that the federal government increase Corporate Average Fuel Economy (CAFE) standards for automobiles and trucks. Other groups push electric cars. The Clinton Administration, for its part, wants the federal government to subsidize the development and sale of alternative'' energy technologies, including solar panels, and is considering new regulations to drive down the use of fossil fuels. An energy tax was proposed five years ago, with little success, so this time other measures will be used to increase the cost of fuel and encourage Americans to do more with less. A virtually identical list of policy prescriptions was trotted out to address the threats of oil depletion, foreign oil dependence, and even global cooling. It seems no matter what the danger, the solution put forward by the environmental establishment is always the same: increase government control over the economy to drive down energy use. Those nations with the greatest governmental controls over their economy suffered the worst environmental catastrophes. Even in market-oriented economies, most major environmental problems can be traced to governmental subsidies or a failure to protect property rights and market institutions. It is time for environmental activists to learn that environmental protection does not require more government. In most instances, it would do better with less. A free-market no regrets'' policy would consist of the following three elements: (1) removing regulatory barriers to innovation; (2) eliminating subsidies to energy use; and (3) deregulating energy-related markets. The benefit of a no regrets policy is that it produces benefits whether or not the threat of climate change is real. Taxpayers benefit from reduced government spending, businesses benefit from

  16. System analysis of energy utilization from waste - evaluation of energy, environment and economy. Case study - Aelvdalen

    International Nuclear Information System (INIS)

    Energy, environmental, and economic consequences of different management systems for municipal solid waste have been studied in a systems analysis. In the systems analysis, different combinations of incineration, materials recycling of separated plastic and cardboard containers, and biological treatment (anaerobic digestion and composting) of easily degradable organic waste, were studied and also compared to landfilling. In the study a computer model (ORWARE) based on LCA methodology was used. The following parameters were used for evaluating the different waste management options: consumption of energy resources, global warming potential, acidification, eutrophication, photo oxidant formation, heavy metal flows, financial economy and welfare economy, where welfare economy is the sum of financial economy and environmental economy. The study shows that reduced landfilling to the benefit of an increased use of energy and material from waste is positive from an environmental and energy as well as economic aspect. This is mainly due to the fact that the choice of waste management method affects processes outside the waste management system, such as production of district heating, vehicle fuel, plastic, cardboard, and fertiliser. This means that landfilling of energy-rich waste should be avoided as far as possible, both because of the the environmental impact, and because of the low recovery of resources. Incineration should constitute a basis in the waste management system of Aelvdalen, even if the waste has to be transported to a regional facility. Once the waste is collected, longer regional transports are of little significance, as long as the transports are carried out in an efficient manner. Comparing materials recycling and incineration, and biological treatment and incineration, no unambiguous conclusions can be drawn. There are benefits and drawbacks associated with all these waste management options. Materials recycling of plastic containers is comparable to

    The historical and undiminished present role of commercial energy forms in fueling human progress is discussed in the context of what are widely believed to be growing environmental and resource limitations. The reasons why forecasts of energy shortages and price escalations have proved so inaccurate are examined, with special emphasis on the experience gained from the recurring Mideast oil crises. The historical record indicates that the interplay of market forces and market-driven technology advances has been vastly more effective in maintaining adequate energy supplies at acceptable prices than most forms of government intervention. Moreover, it seems quite evident that the pursuit of energy autarky has become much too costly for even a superpower in a highly competitive and integrated global economy, and that reliance on an increasingly efficient world energy market best serves the national interest. It is also argued that a collision between growing global energy demand and environmental constraints can best be averted by further advances in the science and technology of energy supply and end use. The most critical element in preventing energy availability from becoming a limiting factor in the advancement of human welfare is the pursuit of least-cost energy service strategies which internalize the cost of all quantifiable externalities, such as the mitigation of quantifiable environmental impacts. However, it is noted that anti-energy elites are obstructing rational solutions to the energy-environment-economy dilemma and are endangering the economic well-being of the industrialized world and the continued social, economic and political progress of the developing world. The yet to be substantiated threat of global warming is cited as the latest issue embraced by these elites to impede economic growth through mandated deviations from least-cost energy service strategies.

    The emission parameters and expose-response functions of some pollutants, such as sulphur dioxide (SO{sub 2}) and Inhalable Particulate Matter (PM10), were introduced to calculate the emission caused by energy consumption in various sectors and regions in China under different scenarios. The impacts of economic growth, population, and technology progress on energy consumption and on the environment were also analyzed. Finally, the economic value of public health damage caused by the changes of pollutants' concentration related to energy consumption under various scenarios, different regions and sectors in China was analyzed. The results show that the PM-10 and SO{sub 2} emissions and consequent health damage will increase significantly in the next 12 years. Thus, energy efficiency, population, economy, and urbanization are the main factors to be considered in this system. (author)

  16. Environment and energy in Iceland: A comparative analysis of values and impacts

    International Nuclear Information System (INIS)

    Within an Icelandic framework plan for energy, environmental values and impacts were estimated in multicriteria analyses for 19 hydroelectric and 22 geothermal developments. Four natural environment classes were defined (geology + hydrology, species, ecosystems + soils, landscape + wilderness) with cultural heritage as the fifth class. Values and impacts were assessed through 6 agglomerated attributes: richness/diversity, rarity, size/continuity/pristineness, information/symbolic value, international responsibility and visual value. The project offers a unique opportunity for comparing environmental values and impacts within a large sample of sites and energy alternatives treated within a common methodological framework. Total values were higher in hydroelectric than in geothermal areas. Hydroelectric areas scored high for cultural heritage (particularly in rarity and information value), landscape and wilderness. Geothermal areas had high bedrock and hydrological diversity and information values, and a high landscape visual value but little cultural heritage. High values were correlated among some classes of the natural environment, all of which are likely to reflect functional relationships. In contrast, cultural heritage values were not related to natural environment values. Overall, landscape and wilderness had the highest mean value and were also most affected by energy development. Over 40% of the hydroelectric development had a predicted mean impact value of > 4 (out of a maximum of 10), compared with 10% of the geothermal projects. Excluding two outsized hydropower options, there was a significant correlation between plant capacity and impact on geology and hydrology but not with other environmental variables

    2015-11-01

    Excitons, trions, biexcitons, and exciton-trion complexes in two-dimensional transition metal dichalcogenide sheets of MoS2, MoSe2, MoTe2, WS2, and WSe2 are studied by means of density functional theory and path-integral Monte Carlo method in order to accurately account for the particle-particle correlations. In addition, the effect of dielectric environment on the properties of these exciton complexes is studied by modifying the effective interaction potential between particles. Calculated exciton and trion binding energies are consistent with previous experimental and computational studies, and larger systems such as biexciton and exciton-trion complex are found highly stable. Binding energies of biexcitons are similar to or higher than those of trions, but the binding energy of the trion depends significantly stronger on the dielectric environment than that of biexciton. Therefore, as a function of an increasing dielectric constant of the environment the exciton-trion complex "dissociates" to a biexciton rather than to an exciton and a trion.

    Asphalt has been modified for the past several decades using various additives, including synthetic polymers. Polymer modification improves structural and engineering characteristics of the binder, which is a result of improvement in rheological characteristics of binder as well as its adhesion capability with the aggregate. Such enhancement inevitably enhances the performance characteristics of hot mix asphalts (HMA) such as fatigue life, resistance to rutting, and thermal cracking. Even though polymer-modified HMA is popular in North America and European countries, its use is still limited in developing countries of Southeast Asia due to high costs associated with its manufacturing, processing, and energy consumption. In this study, a new kind of asphalt modifier derived from animal wastes, such as bones, hides, and flesh commonly known as Bone Glue, is studied. This biomaterial which is a by-product of food and cattle industries is cheap, conveniently available, and produced locally in developing countries. The results of the research study showed that the bone glue can easily be mixed with asphalt without significantly altering the asphalt binder's viscosity and mixing and compaction temperatures of HMA. Additionally, improvements in complex shear modulus for a range of temperatures were also determined and it was found that complex shear modulus was improved by bone glue modification.

    The high charge and high energy (HZE) particle radiation environment in space interacts with spacecraft materials and the human body to create a population of neutrons encompassing a broad kinetic energy spectrum. As an HZE ion penetrates matter, there is an increasing chance of fragmentation as penetration depth increases. When an ion fragments, secondary neutrons are released with velocities up to that of the primary ion, giving some neutrons very long penetration ranges. These secondary neutrons have a high relative biological effectiveness, are difficult to effectively shield, and can cause more biological damage than the primary ions in some scenarios. Ground-based irradiation experiments that simulate the space radiation environment must account for this spectrum of neutrons. Using the Particle and Heavy Ion Transport Code System (PHITS), it is possible to simulate a neutron environment that is characteristic of that found in spaceflight. Considering neutron dosimetry, the focus lies on the broad spectrum of recoil protons that are produced in biological targets. In a biological target, dose at a certain penetration depth is primarily dependent upon recoil proton tracks. The PHITS code can be used to simulate a broad-energy neutron spectrum traversing biological targets, and it account for the recoil particle population. This project focuses on modeling a neutron beamline irradiation scenario for determining dose at increasing depth in water targets. Energy-deposition events and particle fluence can be simulated by establishing cross-sectional scoring routines at different depths in a target. This type of model is useful for correlating theoretical data with actual beamline radiobiology experiments. Other work exposed human fibroblast cells to a high-energy neutron source to study micronuclei induction in cells at increasing depth behind water shielding. Those findings provide supporting data describing dose vs. depth across a water-equivalent medium. This

    Full Text Available Collisions with anthropogenic structures are a significant and well documented source of mortality for avian species worldwide. The bald eagle (Haliaeetus leucocephalus is known to be vulnerable to collision with wind turbines and federal wind energy guidelines include an eagle risk assessment for new projects. To address the need for risk assessment, in this study, we 1 identified areas of northeastern North America utilized by migrating bald eagles, and 2 compared these with high wind-potential areas to identify potential risk of bald eagle collision with wind turbines. We captured and marked 17 resident and migrant bald eagles in the northern Chesapeake Bay between August 2007 and May 2009. We produced utilization distribution (UD surfaces for 132 individual migration tracks using a dynamic Brownian bridge movement model and combined these to create a population wide UD surface with a 1 km cell size. We found eagle migration movements were concentrated within two main corridors along the Appalachian Mountains and the Atlantic Coast. Of the 3,123 wind turbines ≥100 m in height in the study area, 38% were located in UD 20, and 31% in UD 40. In the United States portion of the study area, commercially viable wind power classes overlapped with only 2% of the UD category 20 (i.e., the areas of highest use by migrating eagles and 4% of UD category 40. This is encouraging because it suggests that wind energy development can still occur in the study area at sites that are most viable from a wind power perspective and are unlikely to cause significant mortality of migrating eagles. In siting new turbines, wind energy developers should avoid the high-use migration corridors (UD categories 20 & 40 and focus new wind energy projects on lower-risk areas (UD categories 60-100.

    This thesis analyzes how matters traditionally decided by states because deemed strategic such as cross-border physical energy integration, are now the product of corporate strategy. As a direct result of state divestiture implemented in the scope of a changing model of political economy, corporate bodies have taken on an increasingly important role in the achievement of regional integration. The privatization and ownership transfer of a strategic industry, namely energy, has indeed positioned the private sector at the forefront of regional economic affairs. The study also points out the political impact of private sector-driven projects of infrastructure, particularly between two countries that have been separated by strong antagonism in the recent past, the launching of regional energy integration by private companies has provided the substance that was lacking to governments, even though these were willing to operate a rapprochement. The parameters of foreign policy decisions have been modified and rapprochement has been accelerated as a result of initiatives from the private sector. The thesis thus explores the links between the adoption of a neo-liberal political economy that includes the privatization of the energy sector, regional energy integration, and foreign relations. It analyzes how the transformation of transnational economic ties usually derived from decisions of state can now be the product of private business deals. It emphasizes the role of corporate executives in carrying out projects and shaping a new economic reality that governments have proved to be unable or unwilling to create in the past. Its focus is the Chile-Argentina energy integration process and rapprochement in the nineties. The spread of neo-liberalism in the Southern Cone has taken place in a time of waning alternative discourse on development strategy in the international public arena and of acute sense of development imperative in the so-called emerging economies.

  6. An Novel Algorithm to Speech Endpoint Detection in Noisy Environments Based on Energy-Entropy Method

    2008-12-01

    Full Text Available Endpoint detection, which means distinguishing speech and non-speech segments, is considered as one of the key preprocessing operations in automatic speech recognition (ASR systems. Usually the energy of speech signal and Zero Crossing Rate (ZCR, are used to locate the beginning and ending for an utterance. Both of these methods have been shown to be effective for endpoint detection. However, especially in a high noise environment they fail. In this paper, we integrate the modified Teager approach with the Energy-Entropy Features. In our new algorithm, the Teager Energy is used to determine crude endpoints, and the Energy-Entropy Features are used to make the final decision. The advantage of this method is that there is no need to estimate the background noise. Therefore, it is very helpful for environments when the beginning or ending noise is very strong or there is not enough “silence” at the beginning or at the end of the utterance. Experimental results on Farsi speech show that the accuracy of this algorithm is quite satisfactory and acceptable for speech endpoints detection.

    2010-05-01

    Numerous studies have demonstrated that a vast unexploited source of energy can be derived from the marine environment. Recent evolution of the energy market and looming EU renewable energy uptake targets for 2020 have driven a huge explosion of interest in exploiting this resource, triggering both governments and industry to move forward in undertaking feasibility assessments and demonstration projects for wave, tidal and offshore wind farms across coastlines. The locations which naturally lend themselves to high yield energy capture, are by definition, exposed and may be remote, located far from the end user of the electricity generated. A fundamental constraint to successfully exploiting these resources will be whether electricity generated in high energy, variable and constantly evolving environments can be brought safely and reliably to shore without the need for constant monitoring and maintenance of the subsea cables and landfall sites. In the case of riverine cable crossings superficial sediments would typically be used to trench and bury the cable. High energy coastal environments may be stripped of soft sediments. Any superficial sediments present at the site may be highly mobile and subject to re-suspension throughout the tidal cycle or under stormy conditions. EirGrid Plc. and Mott MacDonald Ireland Ltd. have been investigating the potential for routing a cable across the exposed Shannon estuary in Ireland. Information regarding the geological ground model, meteo-oceanographic and archaeological conditions of the proposed site was limited, necessitating a clear investigation strategy. The investigation included gathering site information on currents, bathymetry and geology through desk studies, hydrographic and geophysical surveys, an intrusive ground investigation and coastal erosion assessments at the landfall sites. The study identified a number of difficulties for trenching and protecting a cable through an exposed environment such as the Shannon

    Builders generally use a 'spec and purchase' business management system (BMS) when implementing energy efficiency. A BMS is the overall operational and organizational systems and strategies that a builder uses to set up and run its company. This type of BMS treats building performance as a simple technology swap (e.g. a tank water heater to a tankless water heater) and typically compartmentalizes energy efficiency within one or two groups in the organization (e.g. purchasing and construction). While certain tools, such as details, checklists, and scopes of work, can assist builders in managing the quality of the construction of higher performance homes, they do nothing to address the underlying operational strategies and issues related to change management that builders face when they make high performance homes a core part of their mission. To achieve the systems integration necessary for attaining 40% + levels of energy efficiency, while capturing the cost tradeoffs, builders must use a 'systems approach' BMS, rather than a 'spec and purchase' BMS. The following attributes are inherent in a systems approach BMS; they are also generally seen in quality management systems (QMS), such as the National Housing Quality Certification program: Cultural and corporate alignment, Clear intent for quality and performance, Increased collaboration across internal and external teams, Better communication practices and systems, Disciplined approach to quality control, Measurement and verification of performance, Continuous feedback and improvement, and Whole house integrated design and specification.

    Full Text Available The evolution of the energy market and the intrinsic worldwide scope of environmental threats, such as climate change, are two elements that have pushed the world towards shared approaches to global governance via bilateral institutions and international regimes. This article, with the aid of an institutionalist approach, presents the current status of the EU-China relationship, which is characterised by high institutionalisation, and it underlines how their bilateral cooperation has progressively focused on energy and climate change-related issues. In particular, the article sheds some light on the linkages between energy, environment and climate change and how these have created the basis for the upgrade of the EU-China bilateral relationship to its current level. To do so, it underlines some of the tools, the main frameworks and some of the key outcomes of their bilateral cooperation in these fields.

    There have been a number of innovative retail wheeling pilot programs offered by investor-owned utilities and their local regulators. These programs are providing retail consumers with energy options heretofore unavailable. These offerings are just the beginning. The business environment in the energy business is rapidly changing with new entrants vying for their share of the new business. The question is what should be the strategies used by these new entrants and how should they be applied. The answer can be found by examining the lessons learned from recent pilot projects, applying one of three generic strategies offered by Michael Porter, and looking for the resultant opportunities. Each part of the answer is described below. In addition, advice for the energy engineer is provided and recommendations for the buyer are offered.

    The objective of the paper is to describe a novel finite element computational method based on a strain energy density function and to implement it in the object-oriented environment. The original energy-based finite element was put into the known standard framework of classes and handled in a different manner. The nonlinear properties of material are defined with a modified strain energy density function. The local relaxation procedure proposed as a method used to resolve a nonlinear problem is implemented in C++ language. The hexahedral element with eight nodes as well as the adaptation of the nonlinear finite element is introduced. The chosen numerical model is made of nearly incompressible hyperelastic material. The application of the proposed element is shown on the example of a rectangular parallelepiped with a hollow port.

    "This report outlines the steps a developer can use when looking to create and implement higher performance standards such as the U.S. Department of Energy (DOE) Zero Energy Ready Home (ZERH) standards in a community. The report also describes the specific examples of how this process was followed by a developer, Forest City, in the Stapleton community in Denver, Colorado. IBACOS described the steps used to begin to bring the DOE ZERH standard to the Forest City Stapleton community based on 15 years of community-scale development work done by IBACOS. As a result of this prior IBACOS work, the team gained an understanding of the various components that a master developer needs to consider and created strategies for incorporating those components in the initial phases of development to achieve higher performance buildings in the community. An automated scoring system can be used to perform an internal audit that provides a detailed and consistent evaluation of how several homes under construction or builders' floor plans compare with the requirements of the DOE Zero Energy Ready Home program. This audit can be performed multiple times at specific milestones during construction to allow the builder to make changes as needed throughout construction for the project to meet Zero Energy Ready Home standards. This scoring system also can be used to analyze a builder's current construction practices and design.

    The high-energy protons and heavy ions from solar energetic particle (SEP) events present hazard to space systems: damage to science instruments/electronics or to astronauts. A reliable estimate of the high-energy particle environment is very important to assure the mission success. Without it, system survivability is often ensured by setting grossly over-conservative mission requirements, resulting in high mission costs, weight and physically large systems. However, at present our ability to reliably predict the space environments for missions not shielded by planetary magnetic fields is surprisingly poor, especially for missions not at 1 AU. The primary reasons for this are that: (1) SEP events are infrequent and sporadic, (2) statistically valid data exist only at 1 AU, and (3) radial dependence of SEP fluxes and fluences is still to be determined. Our ultimate goal is to develop an advanced model that can reliably provide statistical estimates of mission- integrated fluences of SEP high-energy protons and heavy ions for arbitrary trajectories, launches on arbitrary future dates, and an improved radial dependence law. This will be achieved by adopting an approach used in a preliminary Solar Probe mission study, that is, by flying a spacecraft through the database (described below) with an appropriate radial dependence law being applied at each time step. Here we present the preliminary results for a high-energy "proton" model. For the study, we use the data obtained from the instruments onboard the IMP-8 spacecraft: Goddard's Low Energy Detector (LED) and Medium Energy Detector (MED) and the University of Chicago's Cosmic Ray Nuclear Composition (CRNC) telescope. The data set covers the period between 1973, day 305, and 1997, day 319, at 1 AU. All the data were averaged over 6- hour intervals and corrected for background by subtracting non-SEP contributions (i.e., contributions from galactic cosmic rays and spurious instrumental effects).

    Full Text Available Geothermal energy is abundant everywhere in the world. It certainly would be a great benefit for human being once it is produced by a sophisticated technology. Consequently, it would be the biggest console for earth considering environmental sustainability. Unfortunately, the current status of commercial production of geothermal energy primarily from hydrothermal, geopressured, hot dry rock, and magma are limited to a few countries due to technological difficulties and production cost. This paper describes a simple technology where an in situ geothermal plant assisted by a heat pump would act as a high-temperature production (>150°C to provide excellent capacity of energy generation. The issue related to costs is interestingly cheaper on production, comparing to other technologies, such as solar, hydro, wind, and traditional geothermal technology as described in this article. Therefore, it is suggested that heat pump assisted in situ geothermal energy sources has a great potentiality to be a prime energy source in near future. Since the technology has a number of positive characteristics (simple, safe, and provides continuous baseload, load following, or peaking capacity and benign environmental attributes (zero emissions of CO2, SOx, and NOx, it certainly would be an interesting technology in both developed, and developing countries as an attractive option to produce clean energy to confirm a better environment.

    Research on smart environments saturated with ubiquitous computing devices is rapidly advancing while raising serious privacy issues. According to recent studies, privacy concerns significantly hinder widespread adoption of smart home technologies. Previous work has shown that it is possible to infer the activities of daily living within environments equipped with wireless sensors by monitoring radio fingerprints and traffic patterns. Since data encryption cannot prevent privacy invasions exploiting transmission pattern analysis and statistical inference, various methods based on fake data generation for concealing traffic patterns have been studied. In this paper, we describe an energy-efficient, light-weight, low-latency algorithm for creating dummy activities that are semantically similar to the observed phenomena. By using these cloaking activities, the amount of  fake data transmissions can be flexibly controlled to support a trade-off between energy efficiency and privacy protection. According to the experiments using real data collected from a smart home environment, our proposed method can extend the lifetime of the network by more than 2× compared to the previous methods in the literature. Furthermore, the activity cloaking method supports low latency transmission of real data while also significantly reducing the accuracy of the wireless snooping attacks. PMID:25184489
