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

    English. A special committe of the Canadian House of Commons was established on 23 May 1980 to investigate the use of alternative energy sources such as 'gasohol', liquified coal, solar energy, methanol, wind and tidal power, biomass, and propane. In its final report, the committee envisions an energy system for Canada based on hydrogen and electricity, using solar and geothermal energy for low-grade heat. The committe was not able to say which method of generating electricty would dominate in the next century, although it recommends that fossil fuels should not be used. The fission process is not specifically discussed, but the outlook for fusion was investigated, and continued governmental support of fusion research is recommended. The report proposes some improvements in governmental energy organizations and programs

    In a remote coastal region supply of energy from national grid is insufficient for a sustainable development. Integration and optimization of local alternative renewable energy sources is an optional solution of the problem. In this paper we have studied the energetic potential of local sources of renewable energy (water, solar, wind and biomass). A bottom-up energy system optimization model is proposed in order to support planning policies for promoting the use of renewable energy sources. A software, based on multiple factors and constrains analysis for optimization energy flow is proposed, which provides detailed information for exploitation each source of energy, power and heat generation, GHG emissions and end-use sectors. Economical analysis shows that with existing technologies both stand alone and regional facilities may be feasible. Improving specific legislation will foster investments from Central or Local Governments and also from individuals, private companies or small families. The study is carried on the frame work of a FP6 project "Integrated Renewable Energy System."

    2006-01-01

    In a first part, the author proposes an overview of technological developments in the field of power production. He outlines that technological advances may increase assessments of oil and gas reserves but that the associated costs might be too high to keep on exploiting these resources. The problem is almost the same for coal for which the associated costs concern the reduction of pollution and the sequestration and storage of carbon emissions. Nuclear energy avoids this issue of emissions and researches aim at the development of fusion reactors (ITER project) which still are an economic challenge because of their much higher cost in comparison with fission reactors. The author comments the development of renewable energies which however will not be able to replace thermal and nuclear production to face the constant increase of energy consumption. In the second part, the author evokes the various advances in energy production for transports: fuel cells, energy storage, hydrogen storage, and emergence of a hydrogen economy. He finally evokes applications to military propulsions (ground vehicles, marine propulsion, and aircraft propulsion)

    2014-08-01

    The biomethane yield of various energy crops, selected among potential alternatives to maize in the Greater Region, was assessed. The biomass yield, the volatile solids (VS) content and the biochemical methane potential (BMP) were measured to calculate the biomethane yield per hectare of all plant species. For all species, the dry matter biomass yield and the VS content were the main factors that influence, respectively, the biomethane yield and the BMP. Both values were predicted with good accuracy by linear regressions using the biomass yield and the VS as independent variable. The perennial crop miscanthus appeared to be the most promising alternative to maize when harvested as green matter in autumn and ensiled. Miscanthus reached a biomethane yield of 5.5 ± 1 × 10(3)m(3)ha(-1) during the second year after the establishment, as compared to 5.3 ± 1 × 10(3)m(3)ha(-1) for maize under similar crop conditions.

    2008-01-01

    A study of viability of alternative energy sources for typical communities of the North or Northeast of Brazil, which do not have access to the electric energy is performed. Brazil presents a great economic and social disparity among its several regions. There are several poor communities, mainly in regions far from big cities, without electrical energy. The Brazilian government has a program known as 'Luz para Todos' (Light for All). The big challenge of this program is to bring electrical energy for everyone using new alternatives energy sources. In this work initially a literature review was made concerning the following alternative energy source: wind, solar and biomass. These energy sources can be used to supply the demand to bring electrical energy for poor communities. For this work it is intended to choose a community that has population between 1,000 and 10,000 and does not have access to electrical energy. For this community an economic viability study will be made to evaluate alternative energy sources. The best energy source resulted from the point of view of the economic viability study will be implemented in that community. A new study will be performed to evaluate cost and environmental impact. In this new study the future social development of the community caused by the installation of electrical energy will be considered. Also, this best energy source will be compared with the new generation of nuclear reactors, for instance , the IRIS reactor. (author)

  9. Institutional constraints on alternative water for energy: a guidebook for regional assessments

    Energy Technology Data Exchange (ETDEWEB)

    1980-11-01

    Basic information is presented about the legal, political, and social constraints faced by energy developers in the acquisition of water from underground, irrigation return flow, municipal waste, and saline sources. It is a guide to those institutional constraints which are general and pronounced enough to be important for regional assessments. First, attention was focused on the acquisition phase of the water use cycle. Second, constraints were analyzed primarily from a regional, rather than state-by-state, perspective. Emphasis was placed generally on the West - particularly the synfuel-rich Rocky Mountain states, the East, and Mid-West, in that order. Alaska and Hawaii were not surveyed. Third, the study focuses on the constraints associated with groundwater, municipal waste, irrigation return flow, and sea water, in that order. The phrase, institutional constraints, as used in the study, means legal, social, economic, and political restrictions, requirements, circumstances, or conditions that must be anticipated or responded to in order to acquire water for energy development. The study focuses primarily on legal constraints and secondarily on political constraints, because they tend to encompass or reflect other forms of institutional constraints.

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

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

    1989-02-01

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

  18. Alternatives to nuclear energy

    International Nuclear Information System (INIS)

    Terrado, E.N.

    1981-01-01

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

    Taking into consideration the need for a safe energy supply, rising demand for energy worldwide and limited oil reserves, alternative energy resources for bulk power are discussed. They are nuclear fuel, fluidized bed combustion of coal, coal gasification with combined cycle process, coal-oil mixture combustion and MHD power generation process. It is pointed out that the major environmental impact of fossil fuels is in accumulation of greenhouse gases in the atmosphere and air pollution due to sulphur emission. (M.G.B.)

  5. Alternative energy review

    International Nuclear Information System (INIS)

    1991-09-01

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

    White, J R

    1984-01-01

    The paper outlines a computational procedure for comparing the merits of alternative processes to convert solar radiation to heat, electrical power, or chemical energy. The procedure uses the ratio of equipment investment to useful work as an index. Comparisons with conversion counterparts based on conventional fuels are also facilitated by examining this index. The procedure is illustrated by comparisons of (1) photovoltaic converters of differing efficiencies; (2) photovoltaic converters with and without focusing concentrators; (3) photovoltaic conversion plus electrolysis vs photocatalysis for the production of hydrogen; (4) photovoltaic conversion plus plasma arcs vs photocatalysis for nitrogen fixation. Estimates for conventionally-fuelled processes are included for comparison. The reasons why solar-based concepts fare poorly in such comparisons are traced to the low energy density of solar radiation and its low stream time factor resulting from the limited number of daylight hours available and clouds obscuring the sun.

    Renewable energy Technology (RET) becomes the mainstream option for rural Nepal to access modern source of energy. It focuses on the trend of RET applications consisting of biogas technology, solar thermal, micro and Pico hydropower, biomass technology bio fuel technology, wind power technology etc. The RET's which provide both electricity based as well as non electricity based services, have been shown to most immediately meet the needs of a cleaner indoor environment, better quality lightning for education and income generating, activities, alternative cooking fuels and agro processing as well as rural industries. Improved cooking stoves and much more beneficial than other technologies. Wind energy utilization is still not popular. Solar thermal to generate thermal energy to cook, warm and dry, biogas for lighting and cooking services. Micro hydropower for electric as well as mechanical use and solar PV mainly for domestic lighting may become choice. The most important Renewable Energy Technology (RET's) in Nepal are related to Pico hydropower and micro-hydropower, biomass energy (biogas, briquettes, gasifies, improved cooking stoves, bio-fuels etc.) solar photovoltaic energy, solar PV water pumping, solar thermal energy (solar heater, solar dryers, solar cookers etc.) and wind energy (such as wind generators, wind mills etc.). One renowned Non-governmental organization has been established in the Jhapa and Mornag Bhutanese refugee camp. Two families from all the seven camps in Nepal received one solar cooker, one hay box and two cooking posts to each family. Under this programme, a total of 6,850 solar cookers, 12600 hay boxes and 25,200 cooking pots have been distributed 2009. The number of beneficiaries from this program has reached 85,000. Before the distribution of the cookers and the utensils, the instruction and orientation training for the maintenance and repair and operation method was improved. The refugees were divided in 315 groups of 40

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

    Full Text Available By energy sources we understand technologies and materials used to obtain various forms of energy necessary for the development of society. These sources must be in adequate quantities and be conveniently exploited in terms of technical, economic and sustainable perspective. Alternative energy uses the inherent power of natural sources like wind, tides, the sun. Alternative energy is a term used for some energy sources and energy storage technologies. Generally it indicates energies that are nontraditional and have low impact to the environment. The alternative energy term is used in contrast with the term fossil fuel according to some sources, while other sources use it with the meaning of renewable energy purposes.

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

    This conference brought together individuals and representatives from businesses and governments to discuss renewable energy opportunities and barriers in British Columbia regarding the development of low-impact, renewable energy production in the province. Another objective was to identify potential policy initiatives to encourage broader production. Barriers were defined as being market failures which result in sub-optimal allocation of resources by prohibiting the installation of renewable energy technologies (RET) for a particular application or by causing an economical RET application to become uneconomic. The three main categories of barriers were described as being information barriers, financial barriers and institutional barriers. Barriers can be met at various stages of a RET project, including preconception, feasibility studies, design, construction and operation. Some of the barriers that were highlighted during the presentations were: (1) a lack of access to market, (2) lack of access to capital, (3) playing field not level, (4) no renewable energy provincial strategy, (5) lack of public education, and (6) externalities not accounted for in the rate structure. The Green Energy Program at BC Hydro was also discussed with reference to the utility's action plan which includes green and eco-efficient energy, greenhouse gas reductions, hydrogen, eco-efficient improvements to existing generation and transmission, defining a green energy market, a new resource plan, and various Power Smart programs. Some other topics that were raised during the conference were the need for priority policy tools to encourage broader renewable energy production. Recommendations for tools for change were included with these proceedings.

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

    Full Text Available In the modern world the alternative energy sources, which considerably depend on a region, play more and more significant role. However, the transition of regions to new energy sources lead to the change of transport and logistic network configuration. The formation of optimal core transport network today is a guarantee of the successful economic development of a region tomorrow. The present article studies the issue of advanced core transport network development in a region based on the experience of European and Asian countries and the opportunity to adapt the best foreign experience to Russian conditions. On the basis of artificial intelligence methods for forest industry complex of Sverdlovskaya Oblast the algorithm of problem solution of an optimal logistic infrastructure allocation is offered and some results of a regional transport network are presented. These methods allowed to solve the set task in the conditions of information uncertainty. There are suggestions on the improvement of transport and logistic network in the territory of Sverdlovskaya Oblast. Traditionally the logistics of mineral fuel plays main role in regions development. Actually it is required to develop logistic strategic plans to be able to provide different possibilities of power-supply, flexible enough to change with the population density, transport infrastructure and demographics of different regions. The problem of logistic centers allocation was studied by many authors. The approach, offered by the authors of this paper is to solve the set of tasks by applying artificial intelligence methods, such as fuzzy set theory and genetic algorithms.

    A survey was conducted, with environmental matters taken into consideration, for building an information gathering infrastructure for the countries in the Pacific region, capable of promptly and accurately collecting and offering energy related information. Conducted in this fiscal year were regular data gathering, review of oil supply and demand and alternative energy supply and demand in the Pacific region, on-site survey of alternative energy development and utilization in Vietnam, quarterly analyses of trend of energy demand, and the like. The supply of primary energy in the Pacific region increased by 2.3% per year in the period 1980 through 1998. The rate of increase was the lowest with oil, and the highest with hydroelectricity, atomic power, and recoverable energies such as geothermal energy. The Vietnamese Government is promoting its efforts to develop power sources by use of recoverable energies for farm village electrification. Efforts are being earnestly exerted to develop its rich natural gas resources and it is expected that there will be a remarkable achievement in the use of alternative energies due to an increase in natural gas consumption. In the field of data collection, various data were registered with the database. (NEDO)

    1988-01-01

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

    The paper cites three practical propositions to furnish viable green energy in the Biofuels, Clean Coal Processes, and Windmill sectors. We share our experience on indigenous fabrication of 500 W, 1.5 m windmill rotors with a hub height of 6.0 m above ground level as part of NUST-AERO-Fiber Tech outreach industrial link project. Mirror process with matching receptacles is used to fabricate the windmill rotors according to NACA aero foil profile. Full scale load-deflection/bending stiffness tests are conducted using simulated aerodynamic load with incremental loading. An avg. bending stiffness of 14.85 KN/m and mean displacement of 21.17 mm for the maximum applied load of 0.35 KN is recorded at a loading rate of 0.05 KN/sec. for a full scale load range of 25 KN. These results demonstrate that the manufactured composite rotors had adequate structural integrity, subsequently verified in actual windmill operation at 400 rpm. The installed windmill now adorns the skyline of NUST. Fast Track liquid bio fuels are produced from non-edible crop oil using bimodal nano materials. In a process developed at SCME NUST, a conversion to bio diesel time of 5 min. at 25 deg. C is achieved compared to 90 min. at 70 deg. C for the conventional hydroxide catalyst route. The process parameters, characterization and evaluation testing are presented. (author)

    The paper is a pleading in favor of hydroelectric power which in Romania originated more than 100 y ago. The hydroelectric potential of this country amounts to about 40 TWh / year. The hydroelectric yield is currently 15.5 TWh / year, 11.5 TWh / year of which being supplied by the Danube Power Plants. The hydroelectric power has a number of advantages: it is renewable, can be stocked and distributed according to the daily, weekly or seasonal energy demand, the energetic output is 82-89 %, if the project is carefully worked out the hydroelectric system has a small environmental impact, the service life can reach over 80 years, while the maintaining and operation costs are low. Some drawbacks are listed: the problems related to the population relocation, the environmental effects, especially the forest clearing, salt enrichment of affected soils. Arguments are presented from the economic point of view, backed up by ecological and technological advantages in favor of developing the micro hydroelectric power facilities

    This project provides educational opportunities creating both a teaching facility and center for public outreach. The facility is the largest solar array in Nebraska. It was designed to allow students to experience a variety of technologies and provide the public with opportunities for exposure to the implementation of an alternative energy installation designed for an urban setting. The project integrates products from 5 panel manufacturers (including monocrystalline, polycrystalline and thin film technologies) mounted on both fixed and tracking structures. The facility uses both micro and high power inverters. The majority of the system was constructed to serve as an outdoor classroom where panels can be monitored, tested, removed and replaced by students. As an educational facility it primarily serves students in the Creighton University and Metropolitan Community College, but it also provides broader educational opportunities. The project includes a real-time dashboard and a historical database of the output of individual inverters and the corresponding meteorological data for researcher and student use. This allows the evaluation of both panel types and the feasibility of installation types in a region of the country subject to significant temperature, wind and precipitation variation.

    This paper deals with the long-term prospects of alternative fuels in global personal transport. It aims at assessing key drivers and key bottlenecks for their deployment, focusing particularly on the role of biofuels and hydrogen in meeting climate policy objectives. The analysis is pursued using the Global Multi-regional MARKAL model (GMM), a perfect foresight ''bottom-up'' model of the global energy system with a detailed representation of alternative fuel chains, linked to the Model for the Assessment of Greenhouse Gas Induced Climate Change (MAGICC). The analysis shows that biofuels are limited by the regional availability of low-cost biomass, but can be important for meeting mild climate policy targets. If policy-makers intend to pursue more stringent climate policy, then hydrogen becomes a competitive option. However, the analysis finds that the use of hydrogen in personal transport is restricted to very stringent climate policy, as only such policy provides enough incentive to build up the required delivery infrastructure. An analysis of costs additionally shows that ''keeping the hydrogen option open'' does not take considerable investments compared to the investment needs in the power sector within the next decades, but allows the use of hydrogen for the pursuit of stringent climate policy in the second half of the century.

  12. Alternative energy and environmental concerns

    International Nuclear Information System (INIS)

    2002-01-01

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

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

    A cooperative survey by the New York State Energy Office (SEO) and Office of Rural Affairs (ORA) identified hundreds of residences without utility electric power due to excessive line extension costs. SEO selected several of these residences for feasibility studies which compared site specific options for electricity generation, including existing fossil fuel generator(s), generator/battery sets, photovoltaic (PV) hybrid and micro-hydroelectric systems as well as utility provided electric service. Comprehensive reports included examination of a range of energy conservation measures. Alternatives to present fossil fuel systems were assessed for domestic hot water, refrigeration, and water pumping. Results included electric load data, solar and hydroelectric potential, life cycle cost estimates for electricity, and estimated system sizing information based on energy cost considerations. In addition to providing useful information to individual homeowners, these studies served as the basis for cooperative efforts to install and monitor stand-alone prototype PV hybrid systems

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

    It is stated that an important part of the oil and natural gas at present consumed in the UK is used for the heating of buildings, a demand which shows large diurnal, day-to-day and annual fluctuations. The replacement of this energy by nuclear-generated electricity, as at present envisaged, would require the construction of some 250 GW of additional capacity by the end of the century, a programme which does not seem feasible. By incorporating relatively cheap short term storage in the form of low-grade heat, the generating capacity required to fulfil peak demand could be reduced by more than 50%. As soon as such storage is provided, however, other sources of energy should become viable and attractive alternatives, and the UK is well situated to make use of wind, wave, and tidal power. It seems likely that the value of North Sea oil/gas reserves as feedstock to the chemical industry will rise sufficiently to make an early reduction in their consumption as fuel of great economic importance.

    In Scotland the new science curriculum for pupils aged 12 to 15 shall include the following outcomes: "Using my knowledge and understanding, I can express an informed view on a national or global environmental issue;" "I have participated in constructing a model to harness a renewable source of energy and can investigate how to optimise the output;" and "I can discuss why it is important to me and to the future of the world that alternatives to fossil fuels are developed." There will be an emphasis on creating lessons that will nurture responsible citizens, improve pupil engagement and allow students to develop their team working skills. To help teachers plan lessons to address this, the Scottish Schools Equipment Research Centre and Edinburgh University made teaching materials on four renewable energy resources. This poster describes how their suggested activities on solar cells, wind turbines, hydroelectric power stations and wave power were used in science lessons with twelve year old students. After an initial class discussion based on issues related to climate change and diminishing fossil fuel supplies, a workshop activity was carried out in three stages. The students were issued with a fact sheet about one of four imaginary islands (Skisdale, Cloudy Island, Surfsville and Sun City) and they were asked to work in teams to choose the most suitable method of generating electricity for their island. Issues such as costs, where it will be sited and environmental implications were considered. They were then asked to conduct practical activities by constructing and testing models for these forms of renewable energy. To conclude, they presented their proposal to the rest of the class with reasoned explanations. The kits used in the lessons can be purchased from Anderson Scientific (sales@andersonscientific.co.uk). The solar cells were simply connected to a voltmeter. The wind and hydroelectric groups used the same basic equipment. This was made using a small water

    1982-03-01

    Progress in the year 1981 toward the development of energy systems suitable for replacing petroleum products combustion and growing in use to fulfill a near term expansion in energy use is reviewed. Coal is noted to be a potentially heavy pollution source, and the presence of environmentally acceptable methods of use such as fluidized-bed combustion and gasification and liquefaction reached the prototype stage in 1981, MHD power generation was achieved in two U.S. plants, with severe corrosion problems remaining unsolved for the electrodes. Solar flat plate collectors sales amounted to 20 million sq ft in 1981, and solar thermal electric conversion systems with central receivers neared completion. Solar cells are progressing toward DOE goals of $.70/peak W by 1986, while wind energy conversion sales were 2000 machines in 1981, and the industry is regarded as maturing. Finally, geothermal, OTEC, and fusion systems are reviewed.

  13. Energy: the solar hydrogen alternative

    Energy Technology Data Exchange (ETDEWEB)

    Bocheris, J O.M.

    1977-01-01

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

  16. An energy Btu tax alternative

    Nan, Gehuang D.

    1995-01-01

    This paper extends the Ramsey tax rule and develops a tax rate by minimizing total excess burden, subject to government tax revenues. This tax rate is a function of its own and other fuels' price elasticities of compensated demand and supply, its own price and consumption level, other fuels' prices and consumption levels, and government revenues. It is this proposed tax rate, not the Ramsey tax ratio, that guides a government to levy a tax efficiently through a minimization of total excess burden. In the case of an energy tax, this tax rate provides direct guidance for taxation on various fuels. Moreover, total excess burden generated by the proposed tax rate is significantly less than that produced by the Clinton Administration's proposal

    Indian society today is concerned about the health and environmental risks of technologies. The major environmental issues of concern for technologies available for electricity generation are air emissions, management of wastes generated and land requirements. The production of electricity in India is primarily composed of a mix of thermal and hydroelectric power plants with nuclear energy currently contributing to an extent of slightly above 2.0%. For maintaining a decent living standard the present electricity generation has to be increased manifold and with the existing commercially available technologies this can lead to a greater impact on the environment in the immediate vicinity of plant unless a judicious mix is chosen. India which hardly contributed 1 of the global pollution in the year 1950 contributes about 20% now and with the growth in electricity generation its contribution will also be slightly increasing and hence environment will have to be one of the guiding factors in future choice of technologies for the growth of electric power generation. Indian coal has a very high ash content (30 - 50 %) and hence the fly ash problem in India can be severe. During the year 1993-94 approximately 33 million tonnes of fly ash was generated in India from the coal fired thermal power stations. The land requirement for disposal of this ash is continuously increasing. The disposal of fly ash near water bodies will also create difficulties as in addition to radionuclides, toxic trace elements may also get washed out. Pollution from the use of coal will have a definite effect on the environment in addition to depletion of the energy source

  18. ALTERNATIVE SOURCES OF ENERGY - ALTERNATIVE SOURCES OF POLLUTION?

    Directory of Open Access Journals (Sweden)

    2007-06-01

    Full Text Available In many countries of the world investments are made for obtaining energy efficiency, pursuing to increase the generation of non-polluting fuels due to the fact that energy is vital for any economy. The increase in non-polluting fuels and in renewable energy generation might lead to diminishing the dependence of countries less endowed with conventional energy resources on oil and natural gas from Russia or from Arab countries. Nevertheless, environmental issues represent serious questions facing the mankind, requiring the identification, prevention, and why not, their total solving.European Union countries depend on imports of energy, especially on oil imports. At the same time, the European Union countries record a high volume of greenhouse gas emissions, substances adding to global warming. The transport sector is the main consumer of fossil fuels and generator of greenhouse gas emissions. Therefore, diversifying the energy supply used in the transport sector with less polluting sources is an essential objective of the European Union policy in the transport, energy and environment sector. Road transports’ is the sector recording the highest consumption of energy and the highest volume of greenhouse gas emissions.The use of ecologic fuels in the transport sector is an important factor for achieving the objectives of European policies in the field. It is yet to be seen to what extent alternative energy sources are damaging to the environment, as it is a known fact that even for them is recorded a certain level of negative externalities.

  19. Energy Conversion Alternatives Study (ECAS)

    Science.gov (United States)

    1977-01-01

    ECAS compared various advanced energy conversion systems that can use coal or coal-derived fuels for baseload electric power generation. It was conducted in two phases. Phase 1 consisted of parametric studies. From these results, 11 concepts were selected for further study in Phase 2. For each of the Phase 2 systems and a common set of ground rules, performance, cost, environmental intrusion, and natural resource requirements were estimated. In addition, the contractors defined the state of the associated technology, identified the advances required, prepared preliminary research and development plans, and assessed other factors that would affect the implementation of each type of powerplant. The systems studied in Phase 2 include steam systems with atmospheric- and pressurized-fluidized-bed boilers; combined cycle gas turbine/steam systems with integrated gasifiers or fired by a semiclean, coal derived fuel; a potassium/steam system with a pressurized-fluidized-bed boiler; a closed-cycle gas turbine/organic system with a high-temperature, atmospheric-fluidized-bed furnace; a direct-coal-fired, open- cycle magnetohydrodynamic/steam system; and a molten-carbonate fuel cell/steam system with an integrated gasifier. The sensitivity of the results to changes in the ground rules and the impact of uncertainties in capital cost estimates were also examined.

  1. Management alternatives of energy wood thinning stands

    International Nuclear Information System (INIS)

    Heikkilae, Jani; Siren, Matti; Aeijaelae, Olli

    2007-01-01

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

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

    Pakistan, at present facades huge shortage of energy that has disabled several industries and has worsened the living standards of a common man. Its economy mainly depends upon agriculture but relies heavily on imported petroleum to meet the necessities. The importance of national resources as an alternative energy resource is thus greatly felt. The sugar cane industry of Pakistan holds a potential to provide such an alternative fuel as bio ethanol that can be produced entirely from molasses. This paper looks deeper into scope of ethanol as one replacement that can reduce the financial and environmental cost of petroleum based fuels. (author)

    1990-01-01

    This textbook presents a comprehensive picture of the economic aspects, feasibility and adaptability of alternative energy sources and their interconnections. The author intends for this treatment of energy sources to be total and complete. It therefore includes such topics as low temperature and high temperature fuel cells, rechargeable storage batteries (including lead acid, nickel-cadmium, lithium, and sodium-sulfur), Redox flows cells energy system in compatibility with fuel cells and storage batteries, MHD energy systems using non-fossil renewable fuels, solar energy system using direct thermal units and photovoltaic generators, wind energy conversion systems, tidal ocean wave energy converters, geothermal energy, and ocean thermal energy conversion systems. The book is structured so that each major energy source is given one chapter. Each chapter begins with a discussion of the basic structural components of the energy source, as well as operational and fuel characteristics. This is followed by an economic analysis, which includes incremental energy cost curves and economic coordination equations for each possible system of operation. Where appropriate, economic scheduling of generation is applied to several modes of system consumption (e.g., localized dispersed systems, interconnected load centers, and central systems)

  12. Using energy scenarios to explore alternative energy pathways in California

    International Nuclear Information System (INIS)

    Ghanadan, Rebecca; Koomey, J.G.

    2005-01-01

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

    2006-01-01

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

    The paper features a basic outline of the situation in the energy sector of the Czech Republic. It brings information about the current state of the country's energy mix and indicative targets of the State Energy Policy. Though coal and nuclear energy will remain the country's energy staples, great stress is also put on the growth of share of renewable and alternative energy sources. Out of these, the greatest potential in the Czech Republic is that of biomass and waste. To make the use of these sources cost-effective, it is necessary to put stress on heat and power cogeneration.

  15. Water use alternatives for Navajo energy production

    International Nuclear Information System (INIS)

    Abbey, D.

    1979-01-01

    The Navajo have substantial resources of coal and uranium, and water use is certain to accompany development of these resources. A variety of supplies, however, are available--water in storage in Navajo Reservoir, water in existing uses which may be transferred, and groundwater. Furthermore, the quantity of water use varies over a wide range depending on the use of water conservation technologies such as dry coolers and wastewater treatment units. Joint management of energy and water resources requires a basic understanding of the water supply and demand alternatives available to the energy industry. Thus, the uses of water for key energy activities--coal and uranium mining, coal transportation (slurry pipelines), and coal conversion (electricity and synthetic gas production) are reviewed. For those activities for which water conservation is feasible, the technologies and estimate costs ($/af saved) are described. The range of water requirements are then compared to energy and water resource estimates. Finally, alternative (not necessarily exclusive) criteria for energy and water resource management are discussed: a) promote energy activities with the lowest minimum water requirements; b) require industry to use low-quality water resources and the most effective water conservation technology; and c) maximize the economic return on Navajo water resources

    Lower Saxony (Germany) has the highest installed electric capacity from biogas in Germany. Most of this electricity is generated with maize. Reasons for this are the high yields and the economic incentive. In parts of Lower Saxony, an expansion of maize cultivation has led to ecological problems and a negative image of bioenergy as such. Winter triticale and cup plant have both shown their suitability as alternative energy crops for biogas production and could help to reduce maize cultivation. The model Biomass Simulation Tool for Agricultural Resources (BioSTAR) has been validated with observed yield data from the region of Hannover for the cultures maize and winter wheat. Predicted yields for the cultures show satisfactory error values of 9.36% (maize) and 11.5% (winter wheat). Correlations with observed data are significant ( P  alternative to maize in the region of Hanover and other places in Lower Saxony. The model BioSTAR simulated yields for maize and winter wheat in the region of Hannover at a good overall level of accuracy (combined error 10.4%). Due to input data aggregation, individual years show high errors though (up to 30%). Nevertheless, the BioSTAR crop model has proven to be a functioning tool for the prediction of agricultural biomass potentials under varying environmental and crop management frame conditions.

    1980-01-01

    Predictions are made concerning the development of alternative energy sources in the light of the present national energy situation. Particular emphasis is given to the impact of alternative fuels development on aviation fuels. The future outlook for aircraft fuels is that for the near term, there possibly will be no major fuel changes, but minor specification changes may be possible if supplies decrease. In the midterm, a broad cut fuel may be used if current development efforts are successful. As synfuel production levels increase beyond the 1990's there may be some mixtures of petroleum-based and synfuel products with the possibility of some shale distillate and indirect coal liquefaction products near the year 2000.

    Sarlet, W.; Prince, G.

    2010-11-01

    We examine Lagrangian systems on \\ {R}^n with standard kinetic energy terms for the possibility of additional, alternative Lagrangians with kinetic energy metrics different to the Euclidean one. Using the techniques of the inverse problem in the calculus of variations we find necessary and sufficient conditions for the existence of such Lagrangians. We illustrate the problem in two and three dimensions with quadratic and cubic potentials. As an aside we show that the well-known anomalous Lagrangians for the Coulomb problem can be removed by switching on a magnetic field, providing an appealing resolution of the ambiguous quantizations of the hydrogen atom.

    This is a NEDO (New Energy and Industrial Technology Development Organization) report on alternate energy dated November 1, 1988, based on a Koleda Childress and Company of EPA report. As for moves in the US Government, Congress approved an additional budget of $575 million for the Clean Coal Technology Program. President Reagan has signed it and the appropriation will be available in fiscal 1990. The Department of Energy selected sixteen projects for negotiations. It earmarked $382 million for fiscal 1989 for research on fossil fuels with emphasis laid on coal liquefaction, coal combustion systems, heat engines, EOR (enhanced oil recovery), etc. The U.S. Congress has extended for one year the production tax credit for synthetic fuel projects using coal and oil shale as raw materials. The development status is described for the Dow Syngas project and IGCC (integrated gasification combined cycle) technology. The President signed into law the Alternative Motor Fuels Act of 1988, which covers ethanol, methanol, and natural gas. Enactment of an acid rain control act will be put off until 1989. Alternative fuels for the transportation sector are also taken up. Direct methane-to-liquids conversion is an interesting technology. (NEDO)

    Energy supply companies and industrial plants are likely to face new situations due to, for example, the introduction of new energy legislation, increased fuel prices and increased environmental awareness. These new prerequisites provide companies with new challenges but also new possibilities from which to benefit. Increased energy efficiency within companies and increased cooperation between different operators are two alternatives to meet the new conditions. A region characterized by a high density of energy-intensive processes is used in this study to find the economic potential of connecting three industrial plants and four energy companies, within three local district heating systems, to a regional heat market, in which different operators provide heat to a joint district heating grid. Also, different investment alternatives are studied. The results show that the economical potential for a heat market amounts to between 5 and 26 million EUR/year with payback times ranging from two to eleven years. However, the investment costs and the net benefit for the total system need to be allotted to the different operators, as they benefit economically to different extents from the introduction of a heat market. It is also shown that the emissions of CO 2 from the joint system would decrease compared to separate operation of the systems. However, the valuation of CO 2 emissions from electricity production is important as the difference of emitted CO 2 between the accounting methods exceeds 650 kton/year for some scenarios

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

  2. Palm oil as a sustainable energy alternative in degraded areas of the Amazon region; O dende como alternativa energetica sustentavel em areas degradadas na Amazonia

    Bio fuels are important tools in reducing emissions of greenhouse gases (GHG); however, to minimize the conflict with food crops, energy crops with high efficiency and capacity to absorb Co2, such as the oil palm, should be prioritized. The European Union intends to replace 10% of liquid fossil fuel demand with bio fuels by 2020. According to studies conducted by the European Commission, this will entail the annual import of more than 3 million tonnes of palm oil, the most produced and least expensive vegetable oil in the world. 87% of global production comes from Indonesia and Malaysia, where the relentless expansion of oil palm cultivation has caused extensive forest devastation, threatening biodiversity and increasing GHG emissions. The Netherlands, a large importer of oil palm products, developed a methodology (Cramer) for the certification of sustainable bio energy production, assessing economic, social, environmental aspects, as well as GHG emissions, throughout the supply chain. It sets a mandatory minimum 30% reduction of GHG emissions in the bio-energy chain for use in transport and 70% for use in heat and power generation, as compared to the chain of the fossil counterpart. This dissertation shows that oil and bio diesel (ethyl ester) from palm grown in the Amazon meets this GHG mitigation criterion when degraded areas are utilized for cultivation, but not when forests are razed for that purpose.

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

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

    1991-01-01

    For a proposed regional upgrader in Alberta, hydrogen will be needed to upgrade the bitumen and heavy oil to be processed by that facility. The upgrader will rely on high conversion hydrocracking which consumes 3.4 wt % hydrogen to produce a 106% volume yield of high quality synthetic crude. The costs of producing hydrogen via steam reforming of methane, partial oxidation of coal or upgrading residues, and electrolysis are compared, showing that steam reforming is the cheapest. However, an even cheaper source of hydrogen is available in the Edmonton and Fort Saskatchewan area as byproducts from petrochemical plants. An economic analysis is presented of a proposed scheme to capture, purify, compress, and transfer hydrogen from one or two such plants to a nearby regional upgrader. The two plants could supply a total of 126.6 million ft 3 /d of hydrogen at a total installed capital cost of about half of that of a steam reforming plant of equivalent size. When operating costs are added (including the cost of replacing the hydrogen, currently used as fuel at the two plants, with natural gas), the total cost of hydrogen is substantially less than the costs for a hydrogen plant within the upgrader. 3 refs., 5 figs., 4 tabs

Project financing is a concept that assessed by means of financing a specific technique. In this context, those granting funds usually through loans typically are only interested in cash flows and project profit, which are a source of funds for repayment of loans; they are less interested in the creditworthiness of those employed in the project (organizations, governments, communities and so on. This approach has led to the emergence of new ways of financing projects, new types of projects, such as regional and rural development.

    A shortage of electrical distribution capacity can be approached either by reinforcing the existing distribution network or by using demand side management (DSM) to match consumption to existing capacity. Oslo-based E-CO Partner and network owner Viken Nett have recently completed a project on implementing DSM in Oslo. The results of this project are being used in another, ongoing, project, 'New technology for controlling power load in Oslo', which started in 2001. The two projects evaluate the potential for peak load power reduction amongst residential and commercial customers, as well as the potential for saving energy and for selecting alternative energy carriers to electricity. The consequences and limitations of implementing DSM were studied in greater depth in three pilot studies: these included the analysis of metered data, model simulations and comprehensive surveys to map key motivational factors and behaviour amongst a wide selection of end-users. The projects have shown that it is possible, over a 3-4 year period, to reduce or curb the peak load in a city area by 10-15%. This potential is related to a wide type of measures, among them installation of new equipment, replacement of electrical energy carriers, renovation of buildings and installation of smart house solutions. For network owners, the project has shown that DSM measures in a certain city area can be achieved at a cost 30% below that for grid reinforcement. (UK)

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

    This report is the first publication produced within the framework of the WEC's Africa Regional Action Plan as part of the 2005-2007 Work Programme. Presently, over 80% of the total energy consumption in Africa is based on traditional biomass used mostly for cooking. This lack of access to modern energy is holding back economic and social development for 1.6 billion people around the world. The situation is particularly grave in sub-Sahara Africa where over 80% of the population lives in rural areas and the average electrification rate is less than 5%. At least 50 million new connections are needed to provide electricity to supply the non-connected areas in Africa. The over 700 million potential customers represented by these new connections provide a major business opportunity. It is now widely recognised that development assistance, bilateral aid, multilateral financing institutions, a multitude of international aid agencies, NGOs and others have failed to make a significant difference. A new approach is required, otherwise the number of people without access to electricity will continue to grow, and none of the Millennium Development Goals set by the United Nations will be achieved. This regional report highlights key factors that affect cooperative energy projects. The geopolitical context, investment climate and appropriate regulation are just as important as the institutional and technical capacity required to execute many of these projects. The report identifies four key benefits of regional integration: improved security of supply and accessibility; increased economic efficiency; enhanced environmental quality and broader development of renewable resources.

In the eastern region of Antioquia, a great hydraulic resource was found with large rivers, stream and water sources near houses, that don't have possibilities of a rural energy network in a near or faraway future, because of its isolation and low economic capacity. A small hydraulic pico generator was developed for this region with the following characteristics: very small dimensions, low weight, compact and integrated design, easy manufacturing in great volumes with low cost. in its operation it loads one or more stationary batteries that provide electricity to a residence, being used in: illumination, communications and some home appliances. By its operation capacity of 24 hours per day, it would compete in advantage with the photovoltaic panel systems used in isolated regions. Advantages of these plants: It is property of the user; zero expenses in administration and operation, low environmental impact (elimination of dams), protection of micro river basins and automatic operation

    Alternative Energy will be discussed in the context of Distributed Generation, which is defined as a delivery platform for micro-power generation, close to the end-users, that can also supplement regional electricity grids. Many references in the paper pertain to Alberta. This is for two reasons: First, familiarity by the author, and more importantly, Alberta is the first region in Canada that has de-regulated it's electricity sector. De-regulation allows independent and smaller power generators to enter the market. Focussing on Alberta, with some references to other Canadian provinces and USA, electricity consumption trends will be reviewed and the pressures to decentralize electricity generation discussed. Re-structuring of the electricity sector, convergence of power generation and natural gas industries, advances in technologies, and environmental concerns are collectively contributing to the creation of a new business called 'Distributed Generation'. Efficiency benefits of combined heat and power associated with the more prominent emerging distributed generation technologies like micro-turbines and fuel cells, will be highlighted. Areas of research, development and demonstration that will enable the successful deployment of Distributed Generation will be suggested with respect to Generation Technologies, Systems Controls, Supporting Infrastructure, and Socio-Political Barriers. Estimates of investments in the various alternative energy technologies will be presented. Using current trends and emerging technologies the Paper will conclude with some predictions of future scenarios. (author)

    Highlights: • Comprehensive snapshot of regional energy system for decision makers. • Connecting regional sustainability targets and energy planning. • Involving local players in energy planning. - Abstract: Actions for increasing the renewable share in the energy supply and improving both production and end-use energy efficiency are often built into the regional level sustainability targets. Because of this, many local stakeholders such as local governments, energy producers and distributors, industry, and public and private sector operators require information on the current state and development aspects of the regional energy efficiency. The drawback is that an overall view on the focal energy system operators, their energy interests, and future energy service needs in the region is often not available for the stakeholders. To support the local energy planning and management of the regional energy services, an approach for increasing the regional energy efficiency is being introduced. The presented approach can be seen as a solid framework for gathering the required data for energy efficiency analysis and also evaluating the energy system development, planned improvement actions, and the required energy services at the region. This study defines the theoretical structure of the energy efficiency approach and the required steps for revealing such energy system improvement actions that support the regional energy plan. To demonstrate the use of the approach, a case study of a Finnish small-town of Lohja is presented. In the case example, possible actions linked to the regional energy targets were evaluated with energy efficiency analysis. The results of the case example are system specific, but the conducted study can be seen as a justified example of generating easily attainable and transparent information on the impacts of different improvement actions on the regional energy system.

    Energy security issues coupled with increased concern over the natural environment are driving factors behind oil price movements. While it is widely accepted that rising oil prices are good for the financial performance of alternative energy companies, there has been relatively little statistical work done to measure just how sensitive the financial performance of alternative energy companies are to changes in oil prices. In this paper, a four variable vector autoregression model is developed and estimated in order to investigate the empirical relationship between alternative energy stock prices, technology stock prices, oil prices, and interest rates. Our results show technology stock prices and oil prices each individually Granger cause the stock prices of alternative energy companies. Simulation results show that a shock to technology stock prices has a larger impact on alternative energy stock prices than does a shock to oil prices. These results should be of use to investors, managers and policy makers. (author)

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

    The present role of the South African Government in energy policy formulation and implementation is assessed in the light of its possible future evolvement, particularly with reference to the tabling of a White Paper on Energy policy during 1986. The brief of the Ministry of Mineral and Energy Affairs is firstly assessed with particular reference to the energy-related functions of the Department itself and those of the various parastatal and statutory organisations and institutions. The various executive and regulatory functions which circumscribe the involvement of government in energy procurement, production and distribution, are critically reviewed in the light of possible further deregulation and the establishment of a more market-orientated energy economy in South Africa. Secondly, the administrative and consultative mechanisms are identified which are believed to be appropriate for the successful co-ordination of the energy-related interests of government and the private sector. It is argued that history has shown that energy policy decisions in South Africa have essentially been guided by non-energy priorities, in particular geopolitical and strategic considerations. It is foreseen that although this situation will prevail to a greater or lesser degree depending on the measure of energy self-sufficiency which will be achieved, particularly insofar as import-dependency of crude oil is concerned, that the emphasis would, indeed should, shift to national energy priorities and considerations. 12 refs., 2 figs

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

    The purpose of the Daemen Alternative Energy/Geothermal Technologies Demonstration Project is to demonstrate the use of geothermal technology as model for energy and environmental efficiency in heating and cooling older, highly inefficient buildings. The former Marian Library building at Daemen College is a 19,000 square foot building located in the center of campus. Through this project, the building was equipped with geothermal technology and results were disseminated. Gold LEED certification for the building was awarded. 1) How the research adds to the understanding of the area investigated. This project is primarily a demonstration project. Information about the installation is available to other companies, organizations, and higher education institutions that may be interested in using geothermal energy for heating and cooling older buildings. 2) The technical effectiveness and economic feasibility of the methods or techniques investigated or demonstrated. According to the modeling and estimates through Stantec, the energy-efficiency cost savings is estimated at 20%, or $24,000 per year. Over 20 years this represents $480,000 in unrestricted revenue available for College operations. See attached technical assistance report. 3) How the project is otherwise of benefit to the public. The Daemen College Geothermal Technologies Ground Source Heat Pumps project sets a standard for retrofitting older, highly inefficient, energy wasting and environmentally irresponsible buildings that are quite typical of many of the buildings on the campuses of regional colleges and universities. As a model, the project serves as an energy-efficient system with significant environmental advantages. Information about the energy-efficiency measures is available to other colleges and universities, organizations and companies, students, and other interested parties. The installation and renovation provided employment for 120 individuals during the award period. Through the new Center

  3. Physical Alternative to the Dark Energy Paradigm

    Directory of Open Access Journals (Sweden)

    Sapar A.

    2013-12-01

    Full Text Available The physical nature of the presently dominating enigmatic dark energy in the expanding universe is demonstrated to be explainable as an excess of the kinetic energy with respect to its potential energy. According to traditional Friedman cosmology, any non-zero value of the total energy integral is ascribed to the space curvature. However, as we show, in the flat universe the total energy also can be different from zero. Initially, a very small excess of kinetic energy originates from the early universe. The present observational data show that our universe has probably a flat space with an excess of kinetic energy. The evolutionary scenario shows that the universe presently is in the transitional stage where its radial coordinate expansion approaches the velocity of light. A possibility of the closed Bubble universe with the local Big Bang and everlasting expansion is demonstrated. Dark matter can be essentially contributed by the non-relativistic massive neutrinos, which have cooled to very low temperatures and velocities thus favoring the formation of the observed broad equipotential wells in galaxies.

    2017-03-01

    Full Text Available Average income per capita is one of the main indicators of the standard of living. This indicator is widely used in research devoted to poverty, interregional income inequality, and is also the main reference point of success of pursued regional policies. A number of researchers note poor quality of official data on household income and call into question their reliability in some regions of Russia. The main reasons include the following: the scale of shadow economy, especially at the level of some regions; insufficient state financing of respective research; and outdated statistical methods of data processing. The author offers the method of quality checking of official statistical data on income per capita by means of a number of indirect indicators. Application of this method also allows receiving alternative estimates of the average per capita income of the population in regions of the country. On the basis of data for 2013-2014 it is shown that in a number of regions official statistical data are underestimated by more than 20%. The received alternative estimates of the average per capita income can be used in further research in place of official indicators

  8. Economics of alternative energy supply in New Zealand

    Energy Technology Data Exchange (ETDEWEB)

    Walker, B. V.

    1977-10-15

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

    2009-07-01

    In this work possible sources of hydrogen production for the generation of electric energy in a distributed way, with the fuel cell use, had been selected and studied. Three renewable sources (biomass, photovoltaic and wind) have been studied for energy generation in Brazil. For the establishment of numerical values, the main regional agricultural cultures and the amount of biomass in various brazilian states had been evaluated, in the form of waste, capable to be used for future hydrogen production. It was also investigated and evaluated the numerical capacity of hydrogen production from wind and photovoltaic resources for each region in Brazil, considering the electrolytic process. Based on the results, it is possible to demonstrate the potentialities of Brazil for electric energy generation in a planned distributed way, with fossil fuel substitution, and consequently, decreasing the environmental impacts.

    2012-03-01

    Scaling up for alternative energy such as solar, wind, and biofuel raises a number of environmental issues, notably changes in land use and adverse effects on wildlife. Airports offer one of the few land uses where reductions in wildlife abundance and habitat quality are necessary and socially acceptable, due to risk of wildlife collisions with aircraft. There are several uncertainties and limitations to establishing alternative energy production at airports, such as ensuring these facilities do not create wildlife attractants or other hazards. However, with careful planning, locating alternative energy projects at airports could help mitigate many of the challenges currently facing policy makers, developers, and conservationists.

    After having evoked the increasing share of renewable energies in electricity production in Europe and the associated investments, the author outlines the main problems associated with renewable energy: their intermittency, and the fact that they are submitted to quick and important variations which must be managed by the grid. He also evokes economic and financial problems (high taxes in Germany and in France, mandatory purchase mechanisms leading to absurd situations and having consequences on the electricity market). The author discusses the issue of energy storage: storage is expensive and its cost will increase that of the produced energy. However, storage can be interesting if its cost is covered by the income generated by the provided services. Some solutions already exist: pumped-storage power station (PSPS), remotely controlled electric-storage water heaters. The author presents and comments the services which storage can provide: smoothing, spare energy supply, and supply quality. He outlines the importance of a technical-economic analysis for the choice of the best storage solution, but also the need to change the business model

    The paper reviews the use of biomass as a source of energy and shows from a number of examples, particularly the growing of sugar beet for the manufacture of ethanol, that this way of producing fuel is not desirable. On a world basis it is possible that there might be a confrontation between the needs for 'food' and 'technological' calories of which there is already a hint in the so-called 'energy crop strategy'. In conclusion, given the present world food supply position, the intensification of food production should be given priority over attempts to produce fuel from biomass and we should not aim to use the photosynthetic process to provide technical calories. Other ways must be found to provide the latter, and it is suggested that nuclear energy should make an increasing contribution even in the developing countries. (Auth.)

    The space solar power concept is concerned with the use of a Space Power Satellite (SPS) which orbits the earth at geostationary altitude. Two large symmetrical solar collectors convert solar energy directly to electricity using photovoltaic cells woven into blankets. The dc electricity is directed to microwave generators incorporated in a transmitting antenna located between the solar collectors. The antenna directs the microwave beam to a receiving antenna on earth where the microwave energy is efficiently converted back to dc electricity. The SPS design promises 30-year and beyond lifetimes. The SPS is relatively pollution free as it promises earth-equivalence of 80-85% efficient ground-based thermal power plant.

    and is poised to quickly become a multi-million dollar company with clients around the globe. Moreover, USU students and researchers alike are now on the leading edge of the electrified transportation workforce. Finally, the legacy of this DOE investment in electric transportation is continuing at USU with the formation in progress of an industry sponsored research center built around the Electric Roadway and Vehicle (EVR) research facility and test track (http://evr.usu.edu). The research conducted in unconventional energy environmental monitoring and beneficial reuse technologies experienced broad success developing experimental and modeling tools and implementing those tools to better understand environmental impacts of industrial processes used in unconventional energy development in the Utah’s Uintah Basin. Before this project began the USU Uintah Basin branch campus had minimal capability to perform this regionally critical environmental research. This research investment enabled monitoring and modeling equipment and expertise to assess impacts of energy development to all aspects of environmental quality. Laboratory capability for environmental analysis has been developed and engaged along with field testing at multiple locations. Successful campaigns to measure greenhouse gas and hydrocarbon emissions from produced water surface impoundments and leakage from subsurface oil and gas infrastructure were executed. A computer model of meteorological conditions during winter inversion episodes was created, and commercialization efforts are underway for those models. Finally, in the past 24 months, nearly $2 million in non- DOE external funding from state, local, federal and private entities has been awarded to USU Uintah Basin to continue and add to work and capability established by this task. The preceding examples represent a few highlights resulting from the USU Alternative and Unconventional Energy Research and Development project. The following report

    Improving the energy efficiency of building stock, commercial equipment, and household appliances can have a major positive impact on energy use, carbon emissions, and building services. Sub-national regions such as the U.S. states wish to increase energy efficiency, reduce carbon emissions, or adapt to climate change. Evaluating sub-national policies to reduce energy use and emissions is difficult because of the large uncertainties in socioeconomic factors, technology performance and cost, and energy and climate policies. Climate change itself may undercut such policies. However, assessing all of the uncertainties of large-scale energy and climate models by performing thousands of model runs can be a significant modeling effort with its accompanying computational burden. By applying fractional–factorial methods to the GCAM-USA 50-state integrated-assessment model in the context of a particular policy question, this paper demonstrates how a decision-focused sensitivity analysis strategy can greatly reduce computational burden in the presence of uncertainty and reveal the important drivers for decisions and more detailed uncertainty analysis. - Highlights: • We evaluate building energy codes and standards for climate mitigation. • We use an integrated assessment model and fractional factorial methods. • Decision criteria are energy use, CO2 emitted, and building service cost. • We demonstrate sensitivity analysis for three states. • We identify key variables to propagate with Monte Carlo or surrogate models

  18. Environmental effects of alternative energy policies

    International Nuclear Information System (INIS)

    Elsinghorst, D.

    1975-06-01

    The exponential increase of the energy consumption has reduced the possibility to pollute air and land so much that the detrimental external effects of economic activities must be regarded in energy modelling. That means to analyse the interdependent connections between the economic system and the environment and to picture the structure of the real system on a mathematical model. To do this, System Dynamics models were developed. Beside the relevant technical variables also sociological variables such as 'public pressure' or 'lobby pressure' were regarded. So it was possible to break open the 'ceteris paribus' assumption of the constant sociological and political influences. The environmental effect of various policies to meet the energy demand were critically examined in simulation runs. It was demonstrated that the pollution of the atmosphere will decrease in the beginning of the 80ies. This is based on the implementation of a new energy technology with a lower pollution and, on the other side, on the increasing amount of pollution control. (orig.) [de

    The aim of the project is to evaluate possibilities to use agrobiomass for several energy end use sectors. The reference is common European approach where ethanol and rape seed oil is produced for transportation sector. The production costs are approximately 3 - 4 times higher compared to non taxed refinery price of gasoline and diesel fuel. This is also the case for energy crops compared to peat and coal. For Finnish conditions several other options are studied including technical and economical assessments. Solid fuels in form of energy crops like reed canary grass, salix-SRF and straw are evaluated as a feed to multifuel fluid bed boilers and as a futuristic scenario also for flashpyrolysis oil production. Rape seed oil is tested by Neste Oy as a biocomponent in heating oil and as a biocomponent in diesel fuel in engines by VTT. According to present results about 10 - 20 % rape seed oil can be mixed unprocessed to heating oils. Agrofibre production is studied in a laboratory phase with two advanced cooking methods to produce a high value product as a fraction of a biorefinery. The aim of the project is to identify possible research and development paths for future activities. With present prices no agrobiomass is today economically competitive with other fuels. (author)

    Pakistan with its energy-deficient resources is highly dependent on import-oriented energy affected the economy because of repeated energy price hike on international horizon. The energy consumption pattern in Pakistan comprises about two-third in commercial energy and one-third in non-commercial forms. Most of the country's energy requirements are met by oil, gas hydro power, coal, nuclear energy and thermal power. Pakistan meets it's commercial energy requirements indigenously up to 64%. The balance of deficit of 35-40% is met through import. The consumption of various agro-residues and wood as fuel also plays a vital role. The analysis shows that emphasis needs to be placed on new and renewable resources of energy besides adopting technologies for energy conservation. Renewable energy depends on energy income and constitutes the development process. The are several renewable energy options such as biogas technology, micro-hydro power generation, direct solar energy and biomass energy conservation etc. By improving the conservation techniques as designs of solar converters, pre treating the biomass fuel, increasing the effectiveness of carbonization and pyrolysis increases the energy production.

    This report summarizes an investigation into the use of regional and multiregional economic models for estimating the indirect and induced impacts of Federally-mandated energy policies. It includes an examination of alternative types of energy policies that can impact regional economies and the available analytical frameworks for measuring the magnitudes and spatial extents of these impacts. One such analytical system, the National Regional Impact Evaluation System (NRIES), currently operational in the Bureau of Economic Analysis (BEA), is chosen for more detailed investigation. The report summarizes the models capabilities for addressing various energy policy issues and then demonstrates the applicability of the model in specified contexts by developing appropriate input data for three scenarios. These scenarios concern the multi-state impacts of alternative coal-mining-development decisions, multi-regional impacts of macroeconomic change, and the comprehensive effects of an alternative national energy supply trajectory. On the basis of this experience, the capabilities of NRIES for analyzing energy-policy issues are summarized in a concluding chapter.

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

  11. Risk analysis of alternative energy sources

    Kazmer, D.R.

    1982-01-01

    The author explores two points raised by Miller Spangler in a January 1981 issue: public perception of risks involving nuclear power plants relative to those of conventional plants and criteria for evaluating the way risk analyses are made. On the first point, he concludes that translating public attitudes into the experts' language of probability and risk could provide better information and understanding of both the attitudes and the risks. Viewing risk analysis methodologies as filters which help to test historical change, he suggests that the lack of information favors a lay jury approach for energy decisions. Spangler responds that Congress is an example of lay decision making, but that a lay jury, given public disinterest and polarization, would probably not improve social justice on the nuclear issue. 5 references, 4 figures

    2011-01-01

    Economic growth in the countries of Northeast Asia has spurred a massive increase in the need for energy, especially oil, gas, coal, and electricity. Although the region, taken as a whole, possesses financial, technical, labor, and natural resources sufficient to address much of the region's needs now and into the future, no one country has all of those attributes. As a result, over the past two decades, there has been significant interest in regional proposals that would allow sharing of resources, including infrastructure to develop and transport energy resources from the Russian Far East to South Korea, China, and Japan, and cooperation on energy-efficiency, renewable energy, and the nuclear fuel cycle as well. In this article we review some of these proposals, identify some of the factors that could contribute to the success or failure of infrastructure proposals, and explore some of the implications and ramifications of energy cooperation activities for energy security in the region.

    The current international energy trade governance system is fragmented and multi-layered. Streamlining it for greater legal cohesiveness and international political and economic cooperation would promote global energy security. The current article explores three levels of energy trade governance: multilateral, regional and bilateral. Most energy-rich countries are part of the multilateral trading system, which is institutionalized by the World Trade Organization (WTO). The article analyzes the multilateral energy trade governance system by focusing on the WTO and energy transportation issues. Regionally, the article focuses on five major regional agreements and their energy-related aspects and examines the various causes that explain the proliferation of regional trade agreements, their compatibility with WTO law, and then provides several examples of regional energy trade governance throughout the world. When it comes to bilateral energy trade governance, this article only addresses the European Union’s (EU) bilateral energy trade relations. The article explores ways in which gaps could be filled and overlaps eliminated whilst remaining true to the high-level normative framework, concentrating on those measures that would enhance EU energy security.

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

    The exploitation of the energy potential in biomass in a specific geographical region is frequently constrained by high production costs and the amount of land required per unit of energy generated. In addition, the distributed nature of the biomass resource and its normally low energy density may result in large transportation costs. Biomass also requires large land areas to collect and process the incoming solar radiation before the energy can be harvested. Previously published works on regional energy clustering (REC) and the Regional Resources Management Composite Curve, RRMCC (in this paper shortened to RMC), have been extended in this paper to tackle simultaneously the issues of the biomass supply chain, transportation, and land use. The RMC is a tool for supporting decision making in regional resource management. It provides a complete view of energy and land availability in a region, displaying their trade-offs in a single plot. The extension presented in this work has been developed in two steps. The first step presents the Regional Energy Cascade Analysis, which estimates the energy target within regional supply chains and provides the result for energy exchange flows between zones, the quantity of energy required to be imported/exported, and the locations of the demands. In the second step, the initial results are analysed against potential measures for improving the energy and land use targets by using the RMC and a set of rules for its manipulation. The presented method provides the option to assess the priorities: either to produce and sell the surplus energy on the fuel market or use the land for other purposes such as food production. This extended approach is illustrated with a comprehensive case study demonstrating that with the RMC application it is possible to maximise the land use and to maximise the biofuel production for the requested energy demand.

    We present estimates of global energy efficiency by applying second-law (exergy) analysis to regional and global energy balances. We use a uniform analysis of national and regional energy balances and aggregate these balances first for three main economic regions and subsequently into world totals. The procedure involves assessment of energy and exergy efficiencies at each step of energy conversion, from primary exergy to final and useful exergy. Ideally, the analysis should be extended to include actual delivered energy services; unfortunately, data are scarce and only rough estimates can be given for this last stage of energy conversion. The overall result is that the current global primary to useful exergy efficiency is about one-tenth of the theoretical maximum and the service efficiency is even lower. (Author)

    This report has data on population, administration, finance, housing, health and safety, human services, education, and water and sewage for 325 energy-impacted communities. A review of current and potential energy developments in the region shows over 900 energy resource impacts listed for the 325 impacted communities. Coal development represents over one-third of the developments listed. Communities reporting coal development are distributed as follows: Colorado (36), Montana (42), North Dakota (61), South Dakota (13), Utah (73), and Wyoming (35). Energy-conversion initiatives represent another high incidence of energy-resource impact, with uranium development following closely with 83 communities reporting uranium development impact in the region. These projections indicate continued development of regional energy resources to serve national energy requirements. The 325 impacted communities as reported: Colorado (46), Montana (73), North Dakota (62), South Dakota (21), Utah (80), and Wyoming (43) follow a distribution pattern similar to that of future projects which illustrates that no area of the region will escape the impacts of energy development.

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

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

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

    Chinese regional disparities are readily apparent, with well-being seen the highest at the coast and declining steadily inland. Their mitigation will clearly be hostage to improvement in economic development, since the unevenness of that development created them in the first place. Integral to development is structural change, and the key to effecting that change is improved energy efficiency. Indeed, this paper explores energy usage and regional development from 1952 to the present, establishing that they both conform to an inverted-U pattern. Eastern China, the leader in industrialization, has moved beyond the apogee of the curve, but Central and Western China have failed to follow suit, being held back by poor industrial structures and adverse patterns of energy consumption. Remedying this laggardly performance preoccupies China's Government, for rendering the country energy-efficient and containing regional disparities, both rest on pushing the Central and Western regions down the curve in the wake of the prosperous coast.

    The Great Lakes Regional Biomass Energy Program (GLRBEP) was initiated September, 1983, with a grant from the Office of Energy Efficiency and Renewable Energy of the US Department of Energy (DOE). The program provides resources to public and private organizations in the Great Lakes region to increase the utilization and production of biomass fuels. The objectives of the GLRBEP are to: (1) improve the capabilities and effectiveness of biomass energy programs in the state energy offices; (2) assess the availability of biomass resources for energy in light of other competing needs and uses; (3) encourage private sector investments in biomass energy technologies; (4) transfer the results of government-sponsored biomass research and development to the private sector; (5) eliminate or reduce barriers to private sector use of biomass fuels and technology; (6) prevent or substantially mitigate adverse environmental impacts of biomass energy use. The Program Director is responsible for the day-to-day activities of the GLRBEP and for implementing program mandates. A 40 member Technical Advisory Committee (TAC) sets priorities and recommends projects. The governor of each state in the region appoints a member to the Steering Council, which acts on recommendations of the TAC and sets basic program guidelines. The GLRBEP is divided into three separate operational elements. The State Grants component provides funds and direction to the seven state energy offices in the region to increase their capabilities in biomass energy. State-specific activities and interagency programs are emphasized. The Subcontractor component involves the issuance of solicitations to undertake projects that address regional needs, identified by the Technical Advisory Committee. The Technology Transfer component includes the development of nontechnical biomass energy publications and reports by Council staff and contractors, and the dissemination of information at conferences, workshops and other events

    The outlook for energy demand in the Asia-Pacific Economic Cooperation (APEC) region to 2010 is summarized under two scenarios: capacity constraints, in which energy price increases dampen demand, and energy savings, in which energy demand growth is dampened by improvements to the underlying energy intensity trends. In the capacity constraints case, total APEC primary energy demand is projected to increase by more than 50 percent, at an average annual rate of 2.3 percent. Natural gas and solids (mostly coal) are expected to be the fastest growing fossil fuels. In the energy savings case, total primary energy demand could increase by 42 percent, an annual average rate of 2 percent. Projected demands for energy are presented, categorized by fuel: oil demand/supply, natural gas, coal and other solid fuel, electricity and heat, hydroelectric power, and nuclear power.

    The Regional Issues Identification and Assessment (RIIA) program is an evaluation of the regional impacts of future energy development. These studies are conducted for the Department of Energy. The impacts described in this paper for 1990 are based on a national energy projection (scenario) that assumes medium energy demand and fuel supply through 1990, but does not incorporate the policies of the 1978 National Energy Act. The RIIA study plan uses the predicted fuel mixes derived from the PIES scenario as a starting point for its analysis. County level patterns for utility, industry and mining activities for 1990 were then developed from the federal region totals. Energy sources addressed were coal, nuclear, oil, oil shale, gas, geothermal, hydroelectric, and solar. The impact of these county-level patterns of utility, industry, and mining activities on the air, water, and land resources of the country and on the socioeconomic and health and safety aspects of the nation's welfare are analyzed

    China has invested heavily on alternative energy, but the effectiveness of such energy sources at substituting the dominant coal-fired generation remains unknown. Here we analyse the displacement of fossil-fuel-generated electricity by alternative energy, primarily hydropower, and by trans-provincial imported electricity in China between 1995 and 2014 using two-way fixed-effects panel regression models. Nationwide, each unit of alternative energy displaces nearly one-quarter of a unit of fossil-fuel-generated electricity, while each unit of imported electricity (regardless of the generation source) displaces ∼0.3 unit of fossil-fuel electricity generated locally. Results from the six regional grids indicate that significant displacement of fossil-fuel-generated electricity occurs once the share of alternative energy in the electricity supply mix exceeds ∼10%, which is accompanied by 10-50% rebound in the consumption of fossil-fuel-generated electricity. These findings indicate the need for a policy that integrates carbon taxation, alternative energy and energy efficiency to facilitate China's transition towards a low-carbon economy.

  18. Periostin shows increased evolutionary plasticity in its alternatively spliced region

    2010-01-01

    Full Text Available Abstract Background Periostin (POSTN is a secreted extracellular matrix protein of poorly defined function that has been related to bone and heart development as well as to cancer. In human and mouse, it is known to undergo alternative splicing in its C-terminal region, which is devoid of known protein domains. Differential expression of periostin, sometimes of specific splicing isoforms, is observed in a broad range of human cancers, including breast, pancreatic, and colon cancer. Here, we combine genomic and transcriptomic sequence data from vertebrate organisms to study the evolution of periostin and particularly of its C-terminal region. Results We found that the C-terminal part of periostin is markedly more variable among vertebrates than the rest of periostin in terms of exon count, length, and splicing pattern, which we interpret as a consequence of neofunctionalization after the split between periostin and its paralog transforming growth factor, beta-induced (TGFBI. We also defined periostin's sequential 13-amino acid repeat units - well conserved in teleost fish, but more obscure in higher vertebrates - whose secondary structure is predicted to be consecutive beta strands. We suggest that these beta strands may mediate binding interactions with other proteins through an extended beta-zipper in a manner similar to the way repeat units in bacterial cell wall proteins have been reported to bind human fibronectin. Conclusions Our results, obtained with the help of the increasingly large collection of complete vertebrate genomes, document the evolutionary plasticity of periostin's C-terminal region, and for the first time suggest a basis for its functional role.

    Energy and environmental systems have become a well-established component of national and regional planning and management. The University of Wisconsin, in collaboration with the International Institute for Applied Systems Analysis and other institutions, has over the past several years conducted a number of case studies in which a family of energy/environment models was developed and applied to the assessment of alternative policies. This linked set of models, which treats energy demand, energy supply, and environmental impacts, has provided long-term planning information to a spectrum of public and private institution in the regions studied. The philosophy has been to maintain the flexibility to handle rapid change with innovation. 17 references, 7 figures, 1 table.

  3. Long-term alternative energy R and D strategies

    International Nuclear Information System (INIS)

    1981-01-01

    Within the coming decades a transition must be initiated from oil and gas to 'unlimited' primary energy sources, i.e., nuclear and solar energy. Ever more expensive fossil energy forms will have to provide for an intermediary solution to the growing global energy demand. While a rather clear-cut picture of the energy problem has emerged on the global level, a straightforward translation to the national or even to the company level is not available. The current study contract between the European Economic Community and the International Institute for Applied Systems Analysis (IIASA) is a first exercice designed to transfer the global results to the intermediary level of the ''Subregion'' of the European Community. In operational terms the contract aims at identifying long-term (up to 2030) alternative energy R and D strategies for twelve European countries that would be consistent with the global scenarios, identified by IIASA

    Energy choices that are made in a society are also political choices. This article aims to study the extent to which these choices can be reoriented by technological developments related to renewable energies, thus contributing to a redistribution of possibilities and to social reorganization. Three steps are proposed to show that while the development of alternative energies depends on technological advances, it can, in this process, also reveal political potentials: 1) the first step clarifies the theoretical arguments that can be deployed in favour of an approach in terms of 'technological potentialism'; 2) the second step extends this approach by identifying a set of potentials linked to renewable energies and the model that could take shape through these alternative forms; 3) the third step examines how these potentials could find ways of being updated

    The Regional Energy Deployment System (ReEDS) is a deterministic optimization model of the deployment of electric power generation technologies and transmission infrastructure throughout the contiguous United States into the future. The model, developed by the National Renewable Energy Laboratory's Strategic Energy Analysis Center, is designed to analyze the critical energy issues in the electric sector, especially with respect to potential energy policies, such as clean energy and renewable energy standards or carbon restrictions. ReEDS provides a detailed treatment of electricity-generating and electrical storage technologies and specifically addresses a variety of issues related to renewable energy technologies, including accessibility and cost of transmission, regional quality of renewable resources, seasonal and diurnal generation profiles, variability of wind and solar power, and the influence of variability on the reliability of the electrical grid. ReEDS addresses these issues through a highly discretized regional structure, explicit statistical treatment of the variability in wind and solar output over time, and consideration of ancillary services' requirements and costs.

    Policies and current states of alternate energy and global warming concerns in the United States are reported. The House Subcommittee on Energy and Power marking up draft national energy legislation has completed draft titles on the Strategic Petroleum Reserve, energy efficiency, and natural gas, and begun work on an alternate fuel titles. The alternate fuel title includes liquefied petroleum gas, hydrogen, and electricity. A bill on electric vehicles has been approved by the House Science Committee. Under the bill the Department of Energy will establish a cooperative research program of automakers and the electric utility industry to develop advanced batteries for electric vehicles. The bill authorizes a total of $570.5 million for this program for fiscal years 1992 through 1998. At the meeting of the leaders of the seven leading industrialized countries held in London in July, a joint declaration was issued calling for the completion of an effective framework convention on climate change for reducing emissions of carbon dioxide and other greenhouse gases by the time of United Nations Conference on Environment and Development to be called next June.

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

    MAG4 is a technique of forecasting an active region's rate of production of major flares in the coming few days from a free magnetic energy proxy. We present a statistical method of measuring the difference in performance between MAG4 and comparable alternative techniques that forecast an active region's major-flare productivity from alternative observed aspects of the active region. We demonstrate the method by measuring the difference in performance between the “Present MAG4” technique and each of three alternative techniques, called “McIntosh Active-Region Class,” “Total Magnetic Flux,” and “Next MAG4.” We do this by using (1) the MAG4 database of magnetograms and major flare histories of sunspot active regions, (2) the NOAA table of the major-flare productivity of each of 60 McIntosh active-region classes of sunspot active regions, and (3) five technique performance metrics (Heidke Skill Score, True Skill Score, Percent Correct, Probability of Detection, and False Alarm Rate) evaluated from 2000 random two-by-two contingency tables obtained from the databases. We find that (1) Present MAG4 far outperforms both McIntosh Active-Region Class and Total Magnetic Flux, (2) Next MAG4 significantly outperforms Present MAG4, (3) the performance of Next MAG4 is insensitive to the forward and backward temporal windows used, in the range of one to a few days, and (4) forecasting from the free-energy proxy in combination with either any broad category of McIntosh active-region classes or any Mount Wilson active-region class gives no significant performance improvement over forecasting from the free-energy proxy alone (Present MAG4). Key Points Quantitative comparison of performance of pairs of forecasting techniques Next MAG4 forecasts major flares more accurately than Present MAG4 Present MAG4 forecast outperforms McIntosh AR Class and total magnetic flux PMID:26213517

  13. Alternative energy supply strategies for Pakistan and their economic implications

    1984-01-01

    Pakistan is beset with serious energy supply difficulties arising from a fast growing demand for commercial energy, a poor energy resource base and the high cost of imported energy. The commercial energy requirements are expected to rise from 22.4 million tonnes of coal equivalent (tce) in 1980 to 80 million tce by the year 2000 and to about 200 million tce by 2020, while the country's proven fossil-fuel reserves are only 440 million tce and cannot cope with the demand for long. Pakistan is already dependent on imported energy for 90% of its oil requirements or 30% of the total commercial energy, and is spending 5.5% of its gross domestic product (GDP) on energy imports. The paper analyses the economic implications of a few alternative energy supply strategies. These strategies correspond to two different rates of petroleum exploration and development activity, a high and a low average size of new petroleum finds, and the large-scale use of nuclear power starting in 1990 or after the year 2000. It is found that in the most favourable case (high level of petroleum drilling activity with a high success rate and nuclear power use starting in 1990) Pakistan would be able to achieve self-sufficiency in oil by 2010 and in the total energy supply shortly after 2020. The energy sector's investment requirement will, however, increase gradually from 3% of GDP now to almost 6% of GDP by 2020. (author)

  14. Optimal environmental benefits of utilising alternative energy technologies in Jordan

    2004-01-01

    With rapid population growth and increase in industrial activities, more energy is consumed, resulting in environmental pollution and economic difficulties. Therefore, the need for utilising renewable energy resources has emerged. Although Jordan does not have adequate fuel supplies (90% of its crude oil is imported), it is gifted with alternative resources. Because of the political and economical constraints that hinder the import of crude oil from neighbouring countries and of the fact that Jordan has limited fossil fuel resources, strategies to meet energy demand are being addressed and examined together with their consequences and the ways in which they could be utilised. This paper assesses for the first time, the potential of using alternative energy technologies in Jordan, including the utilisation of solar energy for water heating, for wind towers in rural areas and also for biogas production from waste. Approximately 2% of unconventional renewable energy resources are being utilised. The data and scenarios of this study were presented in a manner that would assist decision makers, funding agencies, researchers and other related parties to establish programmes that will be helpful in meeting the energy demand, while preserving the environment and maintaining sustainability.

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

  17. Waste management in the Irkutsk region, Siberia, Russia: An environmental assessment of alternative development scenarios.

    2018-04-01

    The current waste management system, handling around 500,000 t of household, commercial, and institutional waste annually in the Irkutsk region, Siberia, is based on landfilling in an old landfill with no controls of leachate and gas. Life-cycle assessment modelling of the current system shows that it is a major load on the environment, while the simulation of seven alternative systems results in large savings in many impact categories. With respect to climate change, it is estimated that a saving of about 1200 kg CO 2 equivalents is possible per year, per inhabitant, which is a significant reduction in greenhouse gas emissions. The best alternatives involve efficient energy recovery from waste and recycling by source separation for commercial and institutional waste, the major waste type in the Irkutsk region. Recycling of household waste seems less attractive, and it is therefore recommended only to consider this option after experience has been gained with the commercial and institutional waste. Sensitivity analysis shows that recovery of energy - in particular electricity, heat, and steam - from waste is crucial to the environmental performance of the waste management system. This relates to the efficiencies of energy recovery as well as what the recovered energy substitutes, that is, the 'dirtier' the off-set energy, the higher the environmental savings for the waste management system. Since recovered energy may be utilised by only a few energy grids or industrial users, it is recommended to perform additional local assessments of the integration of the waste energy into existing systems and facilities.

    1997-01-01

    In consequence of the national industrial development, it is necessary to supply a lot of energy. This paper presented a discussion about the option of supplying nuclear processed heat as alternative energy sources for industry especially in Java island. The electrical energy requirement can be estimated rising. The stock and the requirement of energy in Indonesia is unbalance. If the oil production rate is constant, such as that of today, it can be estimated that the oil stock would be over in 20 years. The country is trying to difertify its source of energy and reduce its dependence on oil. High Temperature Reactor (HTR) produces electric and also heat at various temperature in the form of steam and gas. Heat processes from a high temperature reactor, could be used in industry for supplying heat for coal hidroforming, gasification of coal, metal annealing, petrochemical hydrogenation, distillation, purification of petrochemicals, evaporation, water heat, etc. (author). 8 refs, 1 fig., 5 tabs

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

    Quantitative signal targeting with alternating radiofrequency labeling of arterial regions (QUASAR) is a recent spin labeling technique that could improve the reliability of brain perfusion measurements. Although it is considered reliable for measuring gray matter as a whole, it has never been evaluated regionally. Here we assessed this regional reliability. Using a 3-Tesla Philips Achieva whole-body system, we scanned four times 10 healthy volunteers, in two sessions 2 weeks apart, to obtain QUASAR images. We computed perfusion images and ran a voxel-based analysis within all brain structures. We also calculated mean regional cerebral blood flow (rCBF) within regions of interest configured for each arterial territory distribution. The mean CBF over whole gray matter was 37.74 with intraclass correlation coefficient (ICC) of .70. In white matter, it was 13.94 with an ICC of .30. Voxel-wise ICC and coefficient-of-variation maps showed relatively lower reliability in watershed areas and white matter especially in deeper white matter. The absolute mean rCBF values were consistent with the ones reported from PET, as was the relatively low variability in different feeding arteries. Thus, QUASAR reliability for regional perfusion is high within gray matter, but uncertain within white matter. © 2014 The Authors.

    Fusion, the process that powers our sun, has long promised to be a virtually inexhaustible source of energy for mankind. No other alternative energy source holds such bright promise, and none has ever presentd such formidable scientific and engineering challenges. Serious research efforts have continued for over 30 years in an attempt to harness and control fusion here on earth. Scientists have made considerable progress in the last decade toward achieving the conditions required for fusion power, and recent experimental results and technological progress have made the scientific feasibility of fusion a virtual certainty. With this knowledge and confidence, the emphasis can now shift toward developing power plants that are practical and economical. Although the necessary technology is not in hand today, the extension to an energy producing system in 20 years is just as attainable as was putting a man on the moon. In the next few decades, the world's population will likely double while the demand for energy will nearly quadruple. Realistic projections show that within the next generation a significant fraction of our electric power must come from alternative energy sources. Increasing environmental concerns may further accelerate this timetable in which new energy sources must be introduced. The continued development of fusion systems to help meet the energy needs of the future will require greater public understanding and support of this technology. The fusion community must do more to make the public aware of the fact that energy is a critical international issue and that fusion is a viable and necessary energy technology that will be safe and economical. 12 refs., 8 figs.

    The growing energy demand in progressing civilization governs the exploitation of various renewable sources over the conventional sources. Wind, Solar, Hydro, Biomass, and waste & Bagasse are the various available renewable sources in India. A reliable nonconventional geothermal source is also available in India but it is restricted to direct heat applications. This study archives the status of renewable alternatives in India. The techno economic factors and environmental aspects associated with each of these alternatives are discussed. This study focusses on prioritizing the renewable sources based on a parameter introduced as Energy Index. This index is evaluated using cumulative scores obtained for each of the alternatives. The cumulative score is obtained by evaluating each alternative over a range of eleven environmental and techno economic criteria following Fuzzy Analytical Hierarchy Process. The eleven criteria's considered in the study are Carbon dioxide emissions (CO 2 ), Sulphur dioxide emissions (SO 2 ), Nitrogen oxide emissions (NO x ), Land requirement, Current energy cost, Potential future energy cost, Turnkey investment, Capacity factor, Energy efficiency, Design period and Water consumption. It is concluded from the study that the geothermal source is the most preferable alternative with highest Energy Index. Hydro, Wind, Biomass and Solar sources are subsequently preferred alternatives. - Highlights: • FAH process is used to obtain cumulative score for each renewable alternative. • Cumulative score is normalized by highest score of ideal source. • Energy Index shows how best a renewable alternative is. • Priority order is obtained for alternatives based on Energy Index. • Geothermal is most preferable source followed by Hydro, Wind, Biomass and Solar.

    As well as summarising the possible alternatives, environmental aspects and uses of LNG, this study aims to investigate the cost involved in the import of LNG to Sweden, from well to user. In Sweden, Natural Gas is used to cover 2 % of the total energy input. The pipeline network stretches from Malmoe to Stenungsund and Gnosjoe, which means some of the most densely populated areas are covered, but there is still 1200 km of the country left, including larger cities such as Stockholm, Uppsala and Linkoeping as well as areas that host some of the most energy demanding industries, e.g. Sundsvall, Umeaa, Luleaa and Kiruna. The absence of Natural Gas typically causes these regions to rely on fuel oil, coke or coal. If these sources of energy could be replaced by Natural Gas, great environmental benefits could be achieved. Research shows that the use of Natural Gas adds 20 % less CO{sub 2} to the atmosphere than oil and also mean lower emissions of NO{sub x}, SO{sub 2} and particles, making it the better alternative from both local and global perspectives. LNG is potentially a fire and an explosion hazard, but in the last 45 years of usage, no major accidents have occurred. Major exporters of LNG are Indonesia, Quatar, Australia and Algeria. Some of the largest importers are Japan, USA, France and Spain. Japan imports nearly 100 % of their Natural Gas as LNG. The available LNG liquefaction capacity increased by 60 % between 2002 and 2007. The total import cost for LNG includes the purchase cost from the producer, the transport cost, be it sea, railroad or road transport, and the cost for the terminal which receives and stores LNG. The study of different routes, volumes and means of transport creates a picture of how the total cost varies in proportion to these parameters. In the calculation of these costs, sources from the industry or estimations of purchase prices, transport costs and terminal costs are used.

  17. Rural and Renewable Energy Project: Renewable and Alternative Energy Devices and Viable Alternatives to Fuelwood and Kerosene

    1997-12-01

    The need for conservation of the nation's trees and other forestry resources so as to make the Government's reafforestation, soil erosion and desertification control programs successful, is a matter that requires serious attention. This is because the bulk of the people of this country, who are in the rural areas, depend massively on fuelwood as their source of energy for cooking. For a large percentage of the urban dwellers, the situation is not much different since the recent increases in the prices of kerosene and liquefied petroleum gas has forced many to opt for fuelwood for cooking. Viable renewable and alternative energy systems like solar cookers, biogas plants, improved wood burning stoves, briquetted biomass and smokeless coal briquettes and stoves are essential for the provision of alternative cooking fuels and methodologies. Furthermore, the inefficient open-to-sun drying method is prevalent, while the rural areas are particularly starved of petroleum products and grid electricity. Modern solar dryers, solar-PV, wind and hydropower can be used to meet some of the energy needs of the rural population. This paper discusses these renewable and alternative devices and how they can be integrated into the Nigerian rural energy system. (author)

  18. Fast rate of evolution in alternatively spliced coding regions of mammalian genes

    2006-04-01

    Full Text Available Abstract Background At least half of mammalian genes are alternatively spliced. Alternative isoforms are often genome-specific and it has been suggested that alternative splicing is one of the major mechanisms for generating protein diversity in the course of evolution. Another way of looking at alternative splicing is to consider sequence evolution of constitutive and alternative regions of protein-coding genes. Indeed, it turns out that constitutive and alternative regions evolve in different ways. Results A set of 3029 orthologous pairs of human and mouse alternatively spliced genes was considered. The rate of nonsynonymous substitutions (dN, the rate of synonymous substitutions (dS, and their ratio (ω = dN/dS appear to be significantly higher in alternatively spliced coding regions compared to constitutive regions. When N-terminal, internal and C-terminal alternatives are analysed separately, C-terminal alternatives appear to make the main contribution to the observed difference. The effects become even more pronounced in a subset of fast evolving genes. Conclusion These results provide evidence of weaker purifying selection and/or stronger positive selection in alternative regions and thus one more confirmation of accelerated evolution in alternative regions. This study corroborates the theory that alternative splicing serves as a testing ground for molecular evolution.

    Policies, programs, and current status of alternate energy and global warming concerns in the United States are reported. As the House and Senate convene for the second session of the 102nd Congress this month, there are indications that both bodies will act on national energy policy legislation this year. In the Senate, it is expected that omnibus energy legislation will be reconsidered relating to oil and gas exploration in ANWR (Arctic National Wildlife Refuge) and CAFE (Corporate Average Fuel Economy) efficiency standards for motor vehicles. Several powerful members of the House Energy and Commerce Committee is urging the Ways and Means Committee to establish a renewable energy production tax credit. At the negotiating sessions of the United Nations-sponsored committee charged with drafting a framework climate convention that took place in Geneva on December 9-20, a draft treaty emerged, but there was little agreement over nearly all of the main provisions of the draft. A joint meeting of energy and environment ministers of the European Community nations has endorsed an energy/carbon tax proposal drafted by the European Commission. The proposed tax would be levied half on energy and half on carbon dioxide and is roughly equivalent to $3 per barrel of oil in 1993 and rising to $10 per barrel by the year 2000. (NEDO)

    2001-01-01

    The magnetic field permeating the solar atmosphere governs much of the structure, morphology, brightness, and dynamics observed on the Sun. The magnetic field, especially in active regions, is thought to provide the power for energetic events in the solar corona, such as solar flares and Coronal Mass Ejections (CME) and is believed to energize the hot coronal plasma seen in extreme ultraviolet or X-rays. The question remains what specific aspect of the magnetic flux governs the observed variability. To directly understand the role of the magnetic field in energizing the solar corona, it is necessary to measure the free magnetic energy available in active regions. The grant now expiring has demonstrated a new and valuable technique for observing the magnetic free energy in active regions as a function of time.

    This research paper is about the depletion of Energy resources being a huge problem facing the world at this time. As available energy sources are coming to a shortage and measures are be taken in order to conserve the irreplaceable energy resources that leads to sustainability and fair use of energy sources for future generations. Alternative energy sources are being sought; however no other energy source is able to provide even a fraction of energy as that of fossil fuels. Use of the alternative energy resources like wind corridors (Sindh and Baluchistan), fair use of Hydro energy (past monsoon flooding can produce enough energy that may available for next century). Uranium Resources which are enough for centuries energy production in Pakistan (Dhok Pathan Formation) lying in Siwalick series from Pliocene to Pleistocene. Among all of these, my focus is about energy from mineral fuels like Uranium from Sandstone hosted deposits in Pakistan (Siwalik Series in Pakistan). A number of uranium bearing mineralized horizons are present in the upper part of the Dhok Pathan Formation. These horizons have secondary uranium mineral carnotite and other ores. Uranium mineralization is widely distributed throughout the Siwaliks The purpose of this paper was to introduce the use of alternative energy sources in Pakistan which are present in enough amounts by nature. Pakistan is blessed with wealth of natural resources. Unfortunately, Pakistan is totally depending on non renewable energy resource. There are three main types of fossil fuels: coal, oil and natural gas. After food, fossil fuel is humanity's most important source of energy. Pakistan is among the most gas dependent economies of the world. Use of fossil fuel for energy will not only increase the demand of more fossils but it has also extreme effects on climate as well as direct and indirect effects to humans. These entire remedial thinking can only be possible if you try to use alternative energy resources rather than

The House and Senate have both approved legislation to fund the Department of Energy's fossil energy program for fiscal 1992. For Department of Energy's fossil energy research and development activities, the final version provides approximately $450 million instead of the $227 million requested by President Bush in February. Of this amount, approximately $57 million is designated to fund coal gasification, coal liquefaction, and oil shale research and development. Last year Congress appropriated $459 million for fossil fuels research and development and $76 million for synthetic fuels. The Environment Ministers of the 12 European Community (EC) member states have given informal approval to a carbon tax proposal drafted last month by the European Commission, the EC's executive body. EC Energy Ministers, however, are less supportive of the approval, and express reluctance to commit EC member states to a carbon tax unless other large energy consumers also agree to limits on CO2 emissions.

    Energy production in Laos is still dominated by traditional fuels. Fuelwood in the main source of energy and most of the energy is consumed at households for cooking. Increase in the number of cars and motorbikes is rapidly increasing the use of imported petroleum products. Electrification is one of the central targets of the Lao government. The electrification rate has increased fast in Laos and in the year 2010 over 70 % households had electricity supply. The target is to have 90 % access to electricity by the year 2020. The World Bank regards the electrification of Lao PDR to be a success story. This paper deals with the present and future energy consumption in Laos. First the historical trends of energy use in different sectors are analysed. The future scenarios are constructed using LaoLinda model. Four different future alternative development paths are analysed using the model results. The energy use data source for the analysis is from the Ministry of Energy and Mines (MEM) of Lao PDR. Economic and other data is from the Department of Statistics of Lao PDR.

    Alternative energy balances aimed to mitigate greenhouse gas (GHG) emissions are developed as alternatives to the baseline energy balance. The section of mitigation options is based on the results of the GHG emission inventory for the 1987 1992 period. The energy sector is the main contributor to the total CO2 emissions of Bulgaria. Stationary combustion for heat and electricity production as well as direct end-use combustion amounts to 80% of the total emissions. The parts of the energy network that could have the biggest influence on GHG emission reduction are identified. The potential effects of the following mitigation measures are discussed: rehabilitation of the combustion facilities currently in operation; repowering to natural gas; reduction of losses in thermal and electrical transmission and distribution networks; penetration of new combustion technologies; tariff structure improvement; renewable sources for electricity and heat production; wasteheat utilization; and supply of households with natural gas to substitute for electricity in space heating and cooking. The total available and the achievable potentials are estimated and the implementation barriers are discussed.

    Full Text Available This paper is related to an alternative energetics microgrid with a wind generator and a hydrogen energy storage system. The main aim of this research is the development of solutions for effective use of the wind generators in alternative energetics devices, at the same time providing uninterrupted power supply of the critical loads. In this research, it was accepted that the alternative energetics microgrid operates in an autonomous mode and the connection to the conventional power grid is not used. In the case when wind speed is low, the necessary power is provided by the energy storage system, which includes a fuel cell and a tank with stored hydrogen. The theoretical analysis of the storage system operation is made. The possible usage time of the stored hydrogen depends on the available amount of hydrogen and the consumption of the hydrogen by the fuel cell. The consumption, in turn, depends on used fuel cell power. The experimental results suggest that if the wind generator can provide only a part of the needed power, the abiding power can be provided by the fuel cell. In this case, a load filter is necessary to decrease the fuel cell current pulsations.

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

  12. Alternate Energy Sources for Thermalplastic Binding Agent Consolidation

    Energy Technology Data Exchange (ETDEWEB)

    Frame, B.J.

    1999-01-01

    A study was conducted to investigate microwave and electron beam technologies as alternate energy sources to consolidate fiber coated with a thermoplastic binding agent into preforms for composite molding applications. Bench experiments showed that both microwave and electron beam energy can produce heat sufficient to melt and consolidate a thermoplastic binding agent applied to fiberglass mat, and several two- and three-dimensional fiberglass preforms were produced with each method. In both cases, it is postulated that the heating was accomplished by the effective interaction of the microwave or electron beam energy with the combination of the mat preform and the tooling used to shape the preform. Both methods contrast with conventional thermal energy applied via infrared heaters or from a heated tool in which the heat to melt the thermoplastic binding agent must diffuse over time from the outer surface of the preform toward its center under a thermal gradient. For these reasons, the microwave and electron beam energy techniques have the potential to rapidly consolidate thick fiber preforms more efficiently than the thermal process. With further development, both technologies have the potential to make preform production more cost effective by decreasing cycle time in the preform tool, reducing energy costs, and by enabling the use of less expensive tooling materials. Descriptions of the microwave and electron beam consolidation experiments and a summary of the results are presented in this report.

  14. Energy Management for Automatic Monitoring Stations in Arctic Regions

    Science.gov (United States)

    Pimentel, Demian

    Automatic weather monitoring stations deployed in arctic regions are usually installed in hard to reach locations. Most of the time they run unsupervised and they face severe environmental conditions: very low temperatures, ice riming, etc. It is usual practice to use a local energy source to power the equipment. There are three main ways to achieve this: (1) a generator whose fuel has to be transported to the location at regular intervals (2) a battery and (3) an energy harvesting generator that exploits a local energy source. Hybrid systems are very common. Polar nights and long winters are typical of arctic regions. Solar radiation reaching the ground during this season is very low or non-existent, depending on the geographical location. Therefore, solar power generation is not very effective. One straightforward, but expensive and inefficient solution is the use of a large bank of batteries that is recharged during sunny months and discharged during the winter. The main purpose of the monitoring stations is to collect meteorological data at regular intervals; interruptions due to a lack of electrical energy can be prevented with the use of an energy management subsystem. Keeping a balance between incoming and outgoing energy flows, while assuring the continuous operation of the station, is the delicate task of energy management strategies. This doctoral thesis explores alternate power generation solutions and intelligent energy management techniques for equipment deployed in the arctic. For instance, harvesting energy from the wind to complement solar generation is studied. Nevertheless, harvested energy is a scarce resource and needs to be used efficiently. Genetic algorithms, fuzzy logic, and common sense are used to efficiently manage energy flows within a simulated arctic weather station.

    As various alternative energy technologies such as photovoltaics, wind, fuel cells, and batteries are emerging as potential sources of energy for the future, the need arises for development of suitable power-conditioning systems to interface these sources to their respective loads. Since most of these sources produce dc electricity and most electrical loads require ac, an important component of the required power-conditioning units is a dc-to-ac inverter. The discussions deal with the development of power conditioners for each alternative energy technology. Discussion topics include assessments of current technology, identification of operational requirements with a comparison of requirements for each source technology, the identification of future technology trends, the determination of mass production and marketing requirements, and recommendations for program direction. Specifically, one working group dealt with source technology: photovoltaics, fuel cells and batteries, and wind followed by sessions discussing system size and application: large grid-connected systems, small grid-connected systems, and stand alone and dc applications. A combined group session provided an opportunity to discuss problems common to power conditioning development.

    The Comunidad Autonoma de Madrid (Autonomous Community of Madrid, in the following Madrid Region), is a region located at the geographical centre of the Iberian Peninsula. Its area is 8.028 km{sup 2}, and its population about five million people. The Department of Economy and Technological Innovation of the Madrid Region, together with some organizations dealing on energy saving and other research institutions have elaborated an Energy Plan for the 2004-12 period. As a part of this work, the Fluid Mechanics Laboratory of the Superior Technical School of Industrial Engineers of the Polytechnic University of Madrid has carried out the assessment of the wind energy resources [Crespo A, Migoya E, Gomez Elvira R. La energia eolica en Madrid. Potencialidad y prospectiva. Plan energetico de la Comunidad de Madrid, 2004-2012. Madrid: Comunidad Autonoma de Madrid; 2004]; using for this task the WAsP program (Wind Atlas Analysis and Application Program), and the own codes, UPMORO (code to study orography effects) and UPMPARK (code to study wake effects in wind parks). Different kinds of data have been collected about climate, topography, roughness of the land, environmentally protected areas, town and village distribution, population density, main facilities and electric power supply. The Spanish National Meteorological Institute has nine wind measurement stations in the region, but only four of them have good and reliable temporary wind data, with time measurement periods that are long enough to provide representative correlations among stations. The Observed Wind Climates of the valid meteorological stations have been made. The Wind Atlas and the resource grid have been calculated, especially in the high wind resource areas, selecting appropriate measurements stations and using criteria based on proximity, similarity and ruggedness index. Some areas cannot be used as a wind energy resource mainly because they have environmental regulation or, in some cases, are very close

    Development efforts are being given on a large wind power generation system which has high reliability and economy and suits the actual situations in Japan. Verification tests will be conducted to establish control systems to realize load leveling against the increase in maximum power demand and the differences in demands between seasons, days and nights. Development will also be made on technologies for systems to operate devices optimally using nighttime power for household use. Solar light and heat energies will be introduced and used widely in housing to achieve efficient comprehensive energy utilization. Wastes, waste heat and unused energies locally available will be utilized to promote forming environment harmonious type energy communities. Photovoltaic and fuel cell power generation facilities will be installed on a trial basis to promote building a groundwork for full-scale installations. Photovoltaic power generation systems will be installed on actual houses to establish technologies to assess and optimize the load leveling effect. Attempts will be made on practical application of high-efficiency regional heat supply systems which utilize such unutilized energies as those from sea water and river water. Assistance will be given through preparing manuals on introduction of wastes power generation systems by local governments, and introduction of regional energy systems by using new discrete type power generation technologies and consumer-use cogeneration systems. 1 fig., 1 tab.

    This book describes and assesses on the basis of the latest research and development projects worldwide what the possibilities are for the realisation of future drive concepts, ranging from battery-driven electromotors to hybrid systems combining electromotor and combustion engine to alternative energy resources such as hydrogen or alcohol. Power density, torque band, acceleration characteristics, specific energy consumption and chemical and noise emissions are the most important criteria for assessing the quality of a drive configuration. The boundary conditions for the introduction of alternative automotive drives are determined by the availability or production characteristics and the storability of the energy resources in question as well as by the degree of technical complexity, costs, safety, infrastructure and service. This book provides an updated overview and analysis of the processes, prime movers and energy resources that can be combined in complex energy management systems for automobiles. Up-to-date information of this kind is indispensable for the development of new concepts. The contents in overview: current data and facts on the development of new concepts; compact overview and analysis of processes, prime movers and energy resources; methods and solutions in designing alternative drives.

    This work is devoted to the evolution of the competition of energy alternative pathway in China, and the influence of energy policy on economic growth by using a dynamical system method. Firstly, the relation between energy and economic growth is taken into account, and a dynamic evolution model is established. It is observed that Hopf bifurcation and chaotic behavior occurs with the varying investment in renewable energy production. Secondly, when there is no policy intervention in energy market, the evolution of competition in energy alternative pathway is also investigated. Thirdly, the system parameters are also identified by using an artificial neural network method on the basis of certain empirical statistical data in China, and the dynamics of the parameters-identified system are studied. Finally, the influences of energy policy on economic growth are empirically analyzed, and some policy recommendations are given based on the results of empirical analysis. - Highlights: • Modeling the energy economy system via the method of dynamic system. • Attaining the chaotic attractor of the energy production and economic system. • Discovering the Hopf bifurcation when the investment changes. • Proposing the alternative pathway of free competition in energy production. • Determining the turning points of parameters related to policy regulation

    Public opinion surveys have been carried out since 1998 on what phase and on what extent of the perception of nuclear energy differs between Japanese dwelling in energy supplying region and an energy-consuming region. Southern Fukui rural district where 15 nuclear reactors are now installed and Osaka urban region of about 100 km apart from Fukui were selected as the respective targets for the energy supplying and consuming regions. Analyses of the data of about 3000 samples have revealed the followings. (1) The public in the nuclear energy supplying region are very friendly to nuclear energy so that only about 20 and 39 of the public are resistive to the general promotion of nuclear energy in Japan and to the construction of another nuclear reactor in their dwelling region, respectively. (2) On the other hand, in the energy-consuming region those respective fractions are 41 and 70 implying strong resistance to nuclear energy in the urban region. (3) Both the degree of interest in and the degree of knowledge on nuclear energy are very low, whereas the extent of fear to nuclear is high for the urban public. (4) Not only the fraction of the public who are satisfied with their present life, but the public fraction who is eagerly support the thought of return-to-nature are very high in the urban region. (5) On the other hand, in the energy supplying region, many peoples eagerly want their life to become more convenient than it is now, and 6) all those trends (I)-(5) are revealed more pronouncedly in the woman than the man. The perception gap of nuclear energy thus became clear between Japanese dwelling in rural and urban regions. On the basis of this knowledge, discussions on the nature of the so-called NIMBY will be made from the socio-psychological viewpoint and propositions will also be made on the methods to dissolve the perception gap of that soft.

    Energy Technology Data Exchange (ETDEWEB)

    The present document is primarily intended to put together and present in a coherent fashion information about the energy in the regions in as complete and up-to-date manner as possible. Data come from: - the general census of the population of 1982, conducted by INSEE; - the enquiry on the receipts and expenses of agricultural undertakings (ERDEXA) which was completed by the Ministry of Agriculture concerning the year 1981; - the annual enquiry on the energy consumption in industry (EACE) covering the year 1982 which was carried out by the Ministry of Industry and Research; the transport enquiry, effected in 1982 by INSEE at the request of the Institute of Research into Transport. The year of reference is therefore as far as possible 1982. These four enquiries form the basis of the four chapters devoted to the residential sector, to agriculture, to industry and to transport. The tertiary, the predominant economic sector which represents over half the jobs, is unfortunately largely unknown as regards energy consumption. It has not been possible to deal with it. The first two chapters give on the one hand the essential economic data on a national and regional level (e.g. the population, employment, income and the GNP) and on the other hand the principal figures concerning production and consumption of energy as well as the distribution systems.

    An emerging global governance is suggested in which the environment is the central organizing principle of civilization. A shift is noted in which transnational, regional, nation-state, local, and tribal structures exist and compete. Nations with strong environmental regulations are more able to meet international competition in such a scenario. It has also been observed in many instances that for managing common resources such as forests and fish stocks, there have been traditional institutions resembling neither state or market but based on such principles as clearly defined boundaries, monitoring of compliance, graduated sanctions, and collective choice arrangements. Examples of a certain kind of well-managed common resource are provided by certain energy utilities which make profits from energy conservation. One such example is the Tennessee Valley Authority, which helps customers install and finance energy-efficient windows for mutual benefit of both parties

    Full Text Available Biogas is a renewable energy which can be used as alternative fuel to replace fossil fuel such as oil and natural gas . Recently, diversification on the use of energy has increasingly become an important issue because the oil sources are depleting . Utilization of agricultural wastes for biogas production can minimize the consumption of commercial energy source such as kerosene as well as the use of firewood . Biogas is generated by the process of organic material digestion by certain anaerobe bacteria activity in aerobic digester . Anaerobic digestion process is basically carried out in three steps i.e. hydrolysis, acidogenic and metanogenic . Digestion process needs certain condition such as C : N ratio, temperature, acidity and also digester design . Most anaerobic digestions perform best at 32 - 35°C or at 50 - 55°C, and pH 6 .8 - 8 . At these temperatures, the digestion process essentially converts organic matter in the present of water into gaseous energy . Generally, biogas consists of methane about 60 - 70% and yield about 1,000 British Thermal Unit/ft 3 or 252 Kcal/0.028 m3 when burned . In several developing countries, as well as in Europe and the United States, biogas has been commonly used as a subtitute environmental friendly energy . Meanwhile, potentially Indonesia has abundant potential of biomass waste, however biogas has not been used maximally .

    This paper summarizes the principles and conceptual design of an integrated alternative energy system for use in typical farming communities in developing countries. A system is described that, utilizing the Sun and methane produced from crop waste, would supply sufficient electric and thermal energy to meet the basic needs of villagers for water pumping, lighting, and cooking. The system is sized to supply enough pumping capacity to irrigate 101 ha (249 acres) sufficiently to optimize annual crop yields for the community. Three economic scenarios were developed, showing net benefits to the community of $3,578 to $15,547 anually, payback periods of 9.5 to 20 years, and benefit-to-cost ratios of 1.1 to 1.9.

    Electron transfer in respiratory chains generates the electrochemical potential that serves as energy source for the cell. Prokaryotes can use a wide range of electron donors and acceptors and may have alternative complexes performing the same catalytic reactions as the mitochondrial complexes. This is the case for the alternative complex III (ACIII), a quinol:cytochrome c/HiPIP oxidoreductase. In order to understand the catalytic mechanism of this respiratory enzyme, we determined the structure of ACIII from Rhodothermus marinus at 3.9 Å resolution by single-particle cryo-electron microscopy. ACIII presents a so-far unique structure, for which we establish the arrangement of the cofactors (four iron-sulfur clusters and six c-type hemes) and propose the location of the quinol-binding site and the presence of two putative proton pathways in the membrane. Altogether, this structure provides insights into a mechanism for energy transduction and introduces ACIII as a redox-driven proton pump.

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

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

    This paper reviews the extensive forms of Asia-Pacific regional cooperation in nuclear power to develop and provide economical and reliable energy supply for sound economical growths of developing countries in this region, which has seen rapid growth of energy consumption more than anywhere else in recent years. Nuclear power has received keen attention from DCs because it can provide a self-reliable energy supply and promote development of high technology in the associated engineering and manufacturing industries locally. However, due to the particular characteristics in nuclear power technology, a close cooperation is required between the seller(industrialized) and buyer(developing) countries. The Asia-Pacific regional cooperation in nuclear power is a step toward providing mutual benefits to the countries involved in this region, and this paper explores potential ways in formulating basic and systematic approaches and areas of full scope cooperation.

    The implementation possibilities of future drive concepts - from hybrid systems comprising an electric motor and an internal combustion engine to fuel cells to alternative fuels like hydrogen or alcohol - will depend largely on quality criteria, e.g. power density, rotary momentum, acceleration characteristics, specific energy consumption, emissions of chemical substances, and noise. The boundary criteria for the introduction of realizeable concepts of alternative drives for motor cars will be defined by the availability and storability of the envisaged fuels, technical complexity, cost, safety, infrastructure and service. The book presents and analyzes the processes, drives and energy sources that can be combined in complex energy management systems for motor cars in accordance with the aforementioned criteria. Knowledge about these facts is indispensable for the development of new concepts. The 2nd edition describes many new developments in car propulsion systems as well as their combinations, new energy sources, energy converters and energy stores.

    In 2004, the total energy consumption in Thailand increased 8.8 per cent, from 47,806 to 60,260 ktoe. Long-range Energy Alternatives Planning (LEAP) is an accounting tool that simulates future energy scenarios. According to a Business As Usual (BAU) case, the overall energy demand in Thailand is estimated to increase from 61,262 to 254,200 ktoe between 2004 and 2030. Commercial energy consumption, which comprises petroleum products, natural gas, coal and its products, and electricity, increased by 9.0 per cent in Thailand in 2004, and new and renewable energy increased by 7.8 per cent. Nearly 60 per cent of the total commercial energy supply in Thailand was imported and increased for a fifth year in a row. The changes in energy consumption can be attributed to population growth and increase in economic activity and development. 10 refs., 5 tabs., 14 figs

    The paper includes some of the results obtained by RATEN ICN Pitesti experts in the IAEA.s Collaborative Project INPRO-SYNERGIES. The case study proposed to evaluate and analyze the nuclear capacity development and increasing of its share in the national energy sector, envisaging the long term national and regional energy sustainability by keeping collaboration options open for the future while bringing solutions to short/medium-term challenges. The following technologies, considered as future competing technologies for electric energy generation in Romania, were selected: nuclear technology (represented by PHWR CANDU Units 3 and 4 - CANDU new, advanced HWR - Adv. HWR, and advanced PWR - Adv. PWR) and, as alternative energy sources, classical technology (represented by Coal-fired power plant using lignite fossil fuel, with carbon capture - Coal_new, and Gas-fired power plant operating on combined cycle, with carbon capture - Gas_new). The study included assessment of specific economic indicators, sensitivity analyses being performed on Levelised Unit Energy Cost (LUEC) variation due to different perturbations (e.g. discount rate, overnight costs, etc). Robustness indices (RI) of LUEC were also calculated by considering simultaneous variation of input parameters for the considered power plants. The economic analyses have been performed by using the IAEA.s NEST program. The study results confirmed that in Romania, under the national specific conditions defined, electricity produced by nuclear power plants is cost competitive against coal and gas fired power plants electricity. The highest impact of considered perturbations on LUEC has been observed for capital intensive technologies (nuclear technologies) comparatively with the classic power plants, especially for discount rate changes.

    Full Text Available This paper analyzes practice and development of new methodological approaches to forecasting the development of regional energy systems. It is shown that the energy complex is involved in a variety of forward and backward linkages as an element of socio-economic systems, and the quality and availability of energy resources largely determines the structure and pace of economic, social and environmental development of the region. Analysis of existing current practice of territorial and sectoral forecasting implemented in Russia and abroad, suggests that such practice is inadequate in its theoretical and methodological elaboration. This is confirmed by the frequent discrepancy between actual results and plans, as well as their regular revision. The methods are mostly based on extrapolation of existing tendencies and not taking into account many factors and emerging trends related to the complexity and openness of the social and economic systems. Post-industrial level of civilization is characterized by fast development of technology; knowledge, information, technological and institutional innovation become the main resources. The greatest importance is attached to such development properties as instability, various orderliness, nonlinearity, interactions etc. Current approaches to forecasting the future are described by a number of theories that are generally called self-organization theory, taking into account these singularities. These concepts should be included in the theoretical basis for the development and implementation of regional development forecasts. Using the synergetic approach assumes that, along with organizational processes, processes of self-organization and self-development are very important in the system, they are characterized by spontaneous, unexpected formations and emerging structures. The development of such systems can generate stable and efficient new structure. The presence of crisis is an integral feature of complex

    The motion of a thin wall is treated in the case where the regions on either side of the wall have vacuum energy. This treatment generalises previous results involving domain walls in vacuum and also previous results involving the properties of false vacuum bubbles. The equation of state for a domain wall is{tau} = {sigma} where {tau} is the tension in the wall and {sigma} is the energy density. We consider the motion of a more general class of walls having equation of state {tau}{Gamma}{sigma} with 0{le}{Gamma}{le}1. Spherically symmetric and planar symmetric walls are examined. We also find the global structure of the wall spacetime. (author).

Starting from LHC and its proposed upgrade HL-LHC, this paper outlines the development of the interaction region design for FCC-hh. We identify energy deposition from debris of the collision events as a driving factor for the layout and draft the guiding principles to unify protection of the superconducting final focus magnets from radiation with a high luminosity performance. Furthermore, we offer a novel strategy to mitigate the lifetime limitation of the first final focus magnet due to radiation load, the Q1 split.

    Line-of-sight magnetograms for 217 active regions (ARs) with different flare rates observed at the solar disk center from 1997 January until 2006 December are utilized to study the turbulence regime and its relationship to flare productivity. Data from the SOHO/MDI instrument recorded in the high-resolution mode and data from the BBSO magnetograph were used. The turbulence regime was probed via magnetic energy spectra and magnetic dissipation spectra. We found steeper energy spectra for ARs with higher flare productivity. We also report that both the power index, α, of the energy spectrum, E(k) ∼ k -α , and the total spectral energy, W = ∫E(k)dk, are comparably correlated with the flare index, A, of an AR. The correlations are found to be stronger than those found between the flare index and the total unsigned flux. The flare index for an AR can be estimated based on measurements of α and W as A = 10 b (αW) c , with b = -7.92 ± 0.58 and c = 1.85 ± 0.13. We found that the regime of the fully developed turbulence occurs in decaying ARs and in emerging ARs (at the very early stage of emergence). Well-developed ARs display underdeveloped turbulence with strong magnetic dissipation at all scales.

  2. Urbanism and energy in developing regions

    Energy Technology Data Exchange (ETDEWEB)

    Meier, R.L.; Berman, S.; Dowell, D.

    1978-03-01

    The pace of urbanization must continue, because in most parts of the world the surplus population in the countryside has nowhere else to go. The world is about 40% urban now and apparently headed for the 80 to 90% share of the total population presently exhibited by the developed countries. Thus, the 1.6 billion urban dwellers in 1978 would become about 3 billion in 1995--if major catastrophes can be avoided. Feasibility assessments for Sao Paulo-Rio de Janeiro, Calcutta, Cairo-Alexandria, Mexico City, and Seoul are presented in the appendices. This analysis-from-a-distance is insufficient to judge how much extra installed electrical generating capacity is required before 1995, the added refining capability for liquid fuels, or the uses for new LNG and coal imports due to be arranged. It is evident that energy (and perhaps also water in most regions) planning is the major determinant of the manner in which these urban areas will adapt to the extraordinary pressures for new settlement. The current round of planning in such metropolitan areas has been addressed to solving traffic-congestion problems, and reorganizing land use in central districts, as the most-pressing issues. Since energy sources and distribution systems now affect the largest and most crucial investments in urban growth it is to be expected that future metropolitan planning may concentrate upon energy efficiency. Energy supplies must be planned to meet requirements set by locally dominant values regarding human services and the environment.

    Most adults do not meet the American College of Sports Medicine and Centers for Disease Control and Prevention (ACSM/CDC) physical activity recommendations. Even fewer meet the more extreme Institute of Medicine (IOM) physical activity recommendations. Compliance with either recommendation has been conventionally assessed by combining frequencies and durations of self-reported activities. Leisure-time energy expenditure is a cumulative measure of activity that offers an alternative method of defining compliance. To calculate the leisure-time energy expenditure of adults complying with the ACSM/CDC or the IOM physical activity recommendations determined by conventional measures and to reexamine compliance with the IOM recommendation using energy expenditure criteria. National, cross-sectional data from the 2000 Behavioral Risk Factor Surveillance System determined the mode, frequency, and duration of up to two leisure-time activities performed by adults. Four mutually exclusive activity groups (Non-, Low-, ACSM/CDC-, and IOM-Active) were defined on the basis of frequencies and durations of reported activities. Leisure-time energy expenditure (kcal x kg(-1) x wk(-1)) was calculated per respondent. The energy expenditure threshold for meeting the IOM recommendation was calculated as 21 kcal x kg(-1) x wk(-1). Of the 162,669 respondents included in the analyses, 29.9% were Nonactive, whereas 42.3%, 23.3%, and 4.5% were Low-, ACSM/CDC-, and IOM-Active, respectively. Median leisure-time energy expenditure values were 9.0, 27.4, and 63.0 kcal x kg(-1) x wk(-1) for Low-, ACSM/CDC-, and IOM-Active groups, respectively. When using energy expenditure criteria, compliance with the IOM recommendation rose to 27.7% of respondents. Compliance with the IOM physical activity recommendation dramatically increased when assessed by energy expenditure compared with conventional criteria, thereby highlighting the potential bias of conventional methods.

    2009-01-01

    White Certificate schemes are currently being implemented or proposed in a growing number of jurisdictions as a means to drive greater energy efficiency uptake. After briefly discussing some of the strengths and weaknesses of such schemes, this paper outlines a proposed alternative approach-the use of Energy Sales Targets. This approach essentially involves the imposition of a cap on the greenhouse gas (GHG) emissions associated with annual energy sales and, in its simplest version, requires no tradeable certificates or permits. The proposed approach creates a clear measurable link between how compliance is enforced (the retailers' targets) and the desired outcomes of the scheme (measurable reductions in GHG emissions). This drives physical additionality of the scheme, including negation of any rebound effect within the covered sectors. It also avoids the need to define the activities eligible to create certificates, and likewise, no deeming, auditing, monitoring or verification would be required by government beyond ensuring retailer compliance-significantly reducing administration costs. There does not appear to be a clear precedent for this type of scheme anywhere in the world, and so this paper should be seen as a preliminary scoping of options that are deserving of more in-depth assessment.

  6. Policy alternatives in reforming energy utilities in developing countries

    Gabriele, Alberto

    2004-01-01

    This paper examines the policy alternatives faced by developing countries in their endeavor to preserve and develop their electricity and gas systems, two service-oriented industries which--along with oil--provide the bulk of energy supply both in developed and in developing countries. Even in very poor countries, industrially generated energy is indispensable for carrying out most economic activities. Therefore, governments traditionally recognize that the supply of gas and electricity entails a fundamental public service dimension. The Introduction presents the case for reforming of energy utilities, discusses in general terms the pros and cons of privatization, and attempts to locate the reforms in a broader historical framework in which developing countries' governments faced characterized by increasing financial hardship. Section 2 constitutes the core of the paper. It reviews the main features of gas and power sector reforms in the developing world and analyzes specifically the cases of five semi-industrialized countries in Latin America and Asia. Section 3 (Concluding remarks) briefly evaluates the country experiences reviewed above and indicates a few policy lessons which can be learnt from them. The main conclusion is that, in a long-run development perspective, full-scale privatization of gas and power sectors in developing countries entails significant risks, and therefore a flexible policy approach is preferable to a rigid commitment to extensive liberalization

    ção de empreendedores, a formação de gestores, a construção de novas habilidades e competências para os agentes do campo criativo. Trata-se, enfim, de se construir e consolidar uma alternativa de superação do atraso social e econômico pelo viés do fomento a empreendimentos criativos, onde o desenvolvimento regional é compreendido como sendo um processo multidimensional, envolvendo a comunidade impregnada de história, suas relações, suas instituições e capaz de conduzir o seu próprio destino. Palavras-chave desenvolvimento regional. economia criativa. políticas públicas. bacia criativa. Programa Nordeste Criativo Abstract This article aims to describe a proposal to promote the productive chains of the creative industries in northeastern Brazil, in the context of a discussion about alternative models of regional development. To achieve this purpose, we performed a literature search in books, journal articles and electronic documents. The study begins with a reflection on the meanings of development and its connections to creativity and innovation. The research is structured in two main areas: the first one deals with the concept of creative industries and the report of its potential to generate economic, cultural, social and technological leverage the positive domestic and foreign trade of creative goods and services; the second one presents a discussion of local and regional development from the concept of 'creative bassin' with a view to a new territorial approach in northeastern Brazil. From these lines, we propose the creative Northeast Program which consists of two fundamental lines of action: the first one refers to the structure and operation of the Centre for Creative Industries in the Northeast (OICNE facing the production and dissemination of knowledge about the creative economy in the region; the second one concerns the establishment and operation of Creative Business Bureaus (BNC, ie, physical spaces for the promotion of sustainable creative

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

    Satisfaction of energy demand in the country especially that of electrical power will depend not only on finding resources but also on appropriate technological choices. As is well known, the supply of electricity itself induces demand. Thus, a scenario of growth of demand chasing the growth of supply will continue for many more years to come. Though conservation measures and increasing share of non-conventional energy supply have their part, coal and hydro based power will have to play the main role in increasing electricity demand in the country. To meet peaking power requirements, regional and national grid would have to use hydro capacity. This would also allow thermal sets to operate at higher PLF. New and upgraded technologies like fluidized bed combustion, coal gasification, gas turbine based combined cycle, power system automation and a number of others in allied fields will be pursued strongly

    National energy policy requires realistic totaling of costs in assessing energy alternatives. The Biomedical and Environmental Assessment Division (BEAD) at Brookhaven is estimating biomedical and environmental costs of energy production and use. All forms of energy, including new technologies, are being considered. Beginning with a compilation of pollutants from the energy system, the various paths to man are traced and health effects evaluated. Excess mortality and morbidity in the U.S. attributable to a total fuel cycle to produce 6.6x10 9 kwh - about a year's production of a 1000-MWe power plant - are being estimated. Where enough information is available, estimates are quantitative. In some instances only the nature of the potential hazard can be described. This assessment aims at providing initial estimates of relative impacts to identify where the important health hazards in each fuel cycle arise, thereby identifying key areas for judging the total costs of alternative energy sources, and those areas of research likely to improve the accuracy of the estimates. It was thus estimated that the production of electric power from all sources in the U.S. in 1975 was associated with between two to nineteen thousand deaths and twenty-nine to fourty-eight thousand disabilities; this is roughly between 0.2 and 2% of total deaths in U.S. ages 1-74. The estimated health effects associated with a total fuel cycle standardized to produce 10 10 kwh electric power were: from coal estimated deaths 20-200, estimated disabilities 300-500; from oil estimated deaths 3-150, estimated disabilities 150-300; from gas estimated deaths 0.2, estimated disabilities 20; from nuclear estimated deaths 1-3, estimated disabilities 8-30. The differences in the year 2000 between health impacts of the U.S. energy system under normal growth expectations and under conditions of a nuclear moratorium were estimated. On the assumption that the nuclear moratorium would require 320 additional 1000-MWe

    An analysis was made of siting issues in the coastal zone, one of the nation's most critical natural resource areas and one which is often the target for energy development proposals. The analysis addressed the changing perceptions of citizens toward energy development in the coastal zone, emphasizing urban communities where access to the waterfront and revitalization of waterfront property are of interest to the citizen. The findings of this analysis are based on an examination of energy development along New Jersey's urban waterfront and along the Texas-Louisiana Gulf Coast, and on redevelopment efforts in Seattle, San Francisco, Boston, and elsewhere. The case studies demonstrate the significance of local attitudes and regional cooperation in the siting process. In highly urbanized areas, air quality has become a predominant concern among citizen groups and an influential factor in development of alternative energy facility siting strategies, such as consideration of inland siting connected by pipeline to a smaller coastal facility. The study addresses the economic impact of the permitting process on the desirability of energy facility investments, and the possible effects of the location selected for the facility on the permitting process and investment economics. The economic analysis demonstrates the importance of viewing energy facility investments in a broad perspective that includes the positive or negative impacts of various alternative siting patterns on the permitting process. Conclusions drawn from the studies regarding Federal, state, local, and corporate politics; regulatory, permitting, licensing, environmental assessment, and site selection are summarized. (MCW)

  12. Using energy efficiency and alternative energy to extend fossil resources or what if tomorrow actually comes

    Moore, M.C.

    2003-01-01

    This PowerPoint presentation outlined the role of energy in maintaining and advancing society, and what happens if we run out of energy. The author provided a glimpse into the energy world through the display of a series of graphs depicting world energy consumption, world energy production, world population distribution, growth rates in Asia, coal use per capita, the United States energy consumption by source, percent of air emissions in the United States from fossil fuel use, and others. It was argued that alternative energy and energy efficiency diminish growth in demand and peak load, supports portfolio diversity, lowers cost, and diminishes environmental impacts. The advances in wind power and solar power were reviewed, as well as advances in bioenergy and hydrogen. The author also argued the case for energy efficiency and conservation. A discussion of various pricing schemes was offered. The first option examined was time of use price, defined as 3 time blocks published in advance for entire seasons. The second option was critical peak pricing, involving a high price imposed for a few days per year when system conditions are critical or near critical. The third option discussed was real-time prices, implying an hourly real-time marginal cost of a kilowatt hour. It was suggested that the system should be changed, since subsidizing energy consumption distorts demand. Energy efficiency and renewables extend fossil energy availability, helping in the transition to a more sustainable world. refs., tabs., figs

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

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

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

    Spatio-temporal entropy (STE) analysis is used as an alternative mathematical tool to identify possible magnetic cloud (MC) candidates. We analyze Interplanetary Magnetic Field (IMF) data using a time interval of only 10 days. We select a convenient data interval of 2500 records moving forward by 200 record steps until the end of the time series. For every data segment, the STE is calculated at each step. During an MC event, the STE reaches values close to zero. This extremely low value of STE is due to MC structure features. However, not all of the magnetic components in MCs have STE values close to zero at the same time. For this reason, we create a standardization index (the so-called Interplanetary Entropy, IE, index). This index is a worthwhile effort to develop new tools to help diagnose ICME structures. The IE was calculated using a time window of one year (1999), and it has a success rate of 70% over other identifiers of MCs. The unsuccessful cases (30%) are caused by small and weak MCs. The results show that the IE methodology identified 9 of 13 MCs, and emitted nine false alarm cases. In 1999, a total of 788 windows of 2500 values existed, meaning that the percentage of false alarms was 1.14%, which can be considered a good result. In addition, four time windows, each of 10 days, are studied, where the IE method was effective in finding MC candidates. As a novel result, two new MCs are identified in these time windows.

    2014-01-01

    This study explores factors related to energy consumers' perceptions of government subsidies for utility provided energy efficiency (EE) programs and for utility providers' use of more clean/alternative energy sources. Demographic factors, attitudes, planned purchases, and perceptions of utility provider motives in relation to governmental and utility provider EE initiatives (i.e. providing discounts and coupons for CFL bulbs), plus the influence of gain- and loss-framed messages are investigated. Over 2000 respondents completed a 16 item phone survey. Hierarchical regression explained 38% of the variance in reactions regarding government subsidies of the cost of utility provided EE programs and 43% of the variance in perceptions involving whether utility companies should use of more clean or alternative forms of energy. Gender and party differences emerged. Loss-framed messages were more important when the issue was government subsidies. Both gain- and loss-framed messages were important when clean/alternative energy was the issue. - Highlights: • Over 2000 ratepayers were surveyed on their attitudes, planned behaviors and perceptions towards energy efficiency programs. • Almost 40% of how ratepayers feel about government subsidies and utility use of clean/alternative energy was explained. • Loss-framed messages were more effective when the dependent variable was ratepayer perception of government subsidies

    Before the United States of America can arrive at a coherent national energy policy, several ongoing debates must be resolved - on environmental hazards, health impacts, and the direct economic consequences of alternative future energy options. No one strategy is obviously correct - or uniquely ethical. Each strategy has its drawbacks, each can be blocked by one or another coalition of interest groups. The public is poorly informed by the media. A single large coal-mine accident is far more extensively reported than a long series of isolated accidents at grade crossings for coal trains, and yet the latter causes more deaths each year. Similarly, the public debate on nuclear issues is focused on low-probability, high-consequence events. It is as though national policy were being framed by a gambler whose motto is 'it's only the stakes and not the odds that matter'. The two authors of this paper come from different disciplines, yet they both believe that the odds do matter. It is essential that the public be well informed about the health risks and the economic consequences of a moratorium on the civilian uses of nuclear energy in the USA. We think that such a moratorium would adversely affect health and the economy. These impacts although small in relation, say, to the overall death rate or to the overall gross national product are not small in an absolute sense The adverse consequences of a moratorium are much more certain, and surely outweigh the impacts of any plausible accident associated with the operation of power reactors.

    A methodology is proposed to estimate the relevant data and to improve the energy efficiency in regional energy planning. The quantification of the regional energy system is subdivided in three independent parameters which are separetely estimated: energy demand, energy consumption, and transformation capacity. Definitions and estimating procedures are given. The optimization of the regional planning includes the application, wherever possible, of the technologies which centralize the space-heating energy production or combine the production of electric energy with space-heating energy distribution.

    Full Text Available Productive forests, as a major source of biomass, represent an important pre-requisite for the development of a bio-economy. In this respect, assessments of biomass availability, efficiency of forest management, forest operations, and economic feasibility are essential. This is certainly the case for Mexico, a country with an increasing energy demand and a considerable potential for sustainable forest utilization. Hence, this paper focuses on analyzing economic alternatives for the Mexican bioenergy supply based on the costs and revenues of utilizing woody biomass residues. With a regional spatial approach, harvesting and transportation costs of utilizing selected biomass residues were stochastically calculated using Monte Carlo simulations. A sensitivity analysis of percentage variation of the most probable estimate in relation to the parameters price and cost for one alternative using net future analysis was conducted. Based on the results for the northern region, a 10% reduction of the transportation cost would reduce overall supply cost, resulting in a total revenue of 13.69 USD/m3 and 0.75 USD/m3 for harvesting residues and non-extracted stand residues, respectively. For the central south region, it is estimated that a contribution of 16.53 USD/m3 from 2013 and a total revenue of 33.00 USD/m3 in 2030 from sawmill residues will improve the value chain. The given approach and outputs provide the basis for the decision-making process regarding forest utilization towards energy generation based on economic indicators.

  4. The Limit of Free Magnetic Energy in Active Regions

    2012-01-01

    By measuring from active-region magnetograms a proxy of the free energy in the active region fs magnetic field, it has been found previously that (1) there is an abrupt upper limit to the free energy the field can hold that increases with the amount of magnetic field in the active region, the active region fs magnetic flux content, and (2) the free energy is usually near its limit when the field explodes in a CME/flare eruption. That is, explosive active regions are concentrated in a main-sequence path bordering the free-energy ]limit line in (flux content, free-energy proxy) phase space. Here, from measurement of Marshall Space Flight Center vector magnetograms, we find the magnetic condition that underlies the free ]energy limit and the accompanying main sequence of explosive active regions. Using a suitable free ]energy proxy measured from vector magnetograms of 44 active regions, we find that (1) in active regions at and near their free ]energy limit, the ratio of magnetic-shear free energy to the non ]free magnetic energy the potential field would have is approximately 1 in the core field, the field rooted along the neutral line, and (2) this ratio is progressively less in active regions progressively farther below their free ]energy limit. This shows that most active regions in which this core-field energy ratio is much less than 1 cannot be triggered to explode; as this ratio approaches 1, most active regions become capable of exploding; and when this ratio is 1 or greater, most active regions are compelled to explode. From these results we surmise the magnetic condition that determines the free ]energy limit is the ratio of the free magnetic energy to the non-free energy the active region fs field would have were it completely relaxed to its potential ]field configuration, and that this ratio is approximately 1 at the free-energy limit and in the main sequence of explosive active regions.

After renovation the buildings will meet the minimum energy performance requirements laid down in Article 4 of the EPBD. The Directive gives room to an alternative approach to achieve the same savings. The Ministry of Interior Affairs has asked ECN to assist with this alternative approach. ECN calculated what saving are achieved with the 3% renovation obligation under the directive. Then ECN looked for the possibilities for an alternative approach to achieve the same savings [Dutch] In artikel 5 van de Energie Efficiency Directive (EED) staat een verplichting om jaarlijks 3% van de gebouwvoorraad van de centrale overheid te renoveren. Die 3% van de gebouwvoorraad moet na renovatie voldoen aan de minimum eisen inzake energieprestatie die door het betreffende lidstaat zijn vastgelegd op grond van artikel 4 in de EPBD. De verplichting betreft gebouwen die in bezit en in gebruik zijn van de rijksoverheid met een gebruiksoppervlakte groter dan 500 m{sup 2}, vanaf juli 2015 groter dan 250 m{sup 2}. De gebouwen die eigendom zijn van de Rijksgebouwendienst betreft kantoren van rijksdiensten, gerechtsgebouwen, gebouwen van douane en politie en gevangenissen. Van de gebouwen van Defensie hoeven alleen kantoren en legeringsgebouwen aan de verplichting te voldoen.

    The tokamak and tandem mirror concepts are compared with alternate confinement concepts using the criteria established in DOE/ET-0047, ''An Evaluation of Alternate Magnetic Fusion Concepts 1977.'' The concepts are evaluated and rated in each of three broad categories: confidence in physics and technology, and reactor desirability. The STARFIRE and MARS reactors are used as a basis for comparing the mainline tokamak and tandem mirror concepts with the alternate concepts evaluated in DOE/ET-0047. Two recent alternate concepts, the ohmically heated toroidal experiment (OHTE) and the compact reversed field pinch reactor (CRFPR), are also evaluated. Results indicate that the physics of the mainline tokamaks and tandem mirrors is better understood than that of most alternate concepts. Both mainline concepts rank near the middle for technology requirements, and both rank near or at the bottom when compared with the reactor desirability of alternate concepts

    The Cogeneration Technology Alternatives Study (CTAS), a program undertaken to identify the most attractive advanced energy conversion systems for industrial cogeneration applications in the 1985-2000 time period, is described, and preliminary results are presented. Two cogeneration options are included in the analysis: a topping application, in which fuel is input to the energy conversion system which generates electricity and waste heat from the conversion system is used to provide heat to the process, and a bottoming application, in which fuel is burned to provide high temperature process heat and waste heat from the process is used as thermal input to the energy conversion system which generates energy. Steam turbines, open and closed cycle gas turbines, combined cycles, diesel engines, Stirling engines, phosphoric acid and molten carbonate fuel cells and thermionics are examined. Expected plant level energy savings, annual energy cost savings, and other results of the economic analysis are given, and the sensitivity of these results to the assumptions concerning fuel prices, price of purchased electricity and the potential effects of regional energy use characteristics is discussed.

    1976-01-01

    Alternate energy forms that can be produced from coal and nuclear energy have been analyzed on efficiency, economic and end-use grounds. These forms include hydrogen, methane, electricity, and EVA-ADAM, a 'chemical heat pipe' approach to energy transmission. The EVA-ADAM system for nuclear heat appears to be economically competitive with the other energy carriers except over very large distances. The cost of hydrogen derived from coal is approximately equal to that of methane derived from the same source when compared on an equal BTU basis. Thermochemically derived hydrogen from nuclear energy shows a break-even range with hydrogen derived from coal at coal costs of from Pound33 to 80/ton depending on the cost of nuclear heat. Electricity and electrolytically derived hydrogen are the most expensive energy carriers and electricity's use should be limited to applications involving work rather than heat. Continued work in thermochemical hydrogen production schemes should be supported as an energy option for the future. (author)

    1994-01-01

    The system used for preparing energy balances for Styria and 17 Styrian districts, which was developed by ADIP-GRAZ in accordance with the federal energy balance of Austria, is being applied to Slovenia. Energy balances are a necessary tool for monitoring the impact of measures initiated by the energy policy. Therefore balances are of a basic mutual interest, also in connection with balances of air pollutants that can be calculated from energy balances. The official Slovenian energy balance for the year 1990 is the basis for implementation of regional balances for five chosen regions (Maribor region, Celje region, Ljubljana region, Littoral region, and Upper-Slovenia region). Results are presented according to defined concepts and structures which are closely related to the MEDEE-RS methodology. (Author)

    Climate is a major determinant of energy demand. Changes in climate may alter energy demand as well as energy demand patterns. This study investigates the implications of climate change for energy demand under the hypothesis that impacts are scale dependent due to region-specific climatic variables, infrastructure, socioeconomic, and energy use profiles. In this analysis we explore regional energy demand responses to climate change by assessing temperature-sensitive energy demand in the Commonwealth of Massachusetts. The study employs a two-step estimation and modeling procedure. The first step evaluates the historic temperature sensitivity of residential and commercial demand for electricity and heating fuels, using a degree-day methodology. We find that when controlling for socioeconomic factors, degree-day variables have significant explanatory power in describing historic changes in residential and commercial energy demands. In the second step, we assess potential future energy demand responses to scenarios of climate change. Model results are based on alternative climate scenarios that were specifically derived for the region on the basis of local climatological data, coupled with regional information from available global climate models. We find notable changes with respect to overall energy consumption by, and energy mix of the residential and commercial sectors in the region. On the basis of our findings, we identify several methodological issues relevant to the development of climate change impact assessments of energy demand

  5. Regional and global significance of nuclear energy

    Schilling, H.D.

    1995-01-01

    Measures to combat poverty and improve the standard of living in countries of the Third World will inevitably boost global demand for energy, and energy conservation measures will not be able to offset this increase. Nuclear energy will regain significance in the framework of approaches adopted to resolve the energy problem, which primarily is an ecologic problem created by an extremely large flow of materials. The extraordinarily high energy density of nuclear fuels can contribute to markedly reduce the flow of materials; and at that, electric energy is an efficient substitute for primary energy forms. Thus nuclear electricity generation is of double benefit to the ecology. Engineering goals in nuclear technology thus gain a service aspect, with progress in power plant engineering and design aiming not only at enhanced engineered safety, but also at regaining public acceptance of and confidence in nuclear power plant technology.

    Bioenergy is the energy released from the reaction of organic carbon material with oxygen. The organic material derived from plants and animals is also referred to as biomass. Biomass is a flexible feedstock capable of conversion into solid, liquid and gaseous fuels by chemical and biological processes. These intermediate biofuels (such as methane gas, ethanol, charcoal) can be substituted for fossil based fuels. Wood and charcoal are important as household fuels and for small scale industries such as brick making, cashew processing etc. The scarcity of biofuels has far reaching implications on the environment. Hence, expansion of bioenergy systems could be influential in bettering both the socioeconomic condition and the environment of the region. This paper examines the present role of biomass in the region's (Uttara Kannada District, Karnataka State, India) energy supply and calculates the potential for future biomass provision and scope for conversion to both modern and traditional fuels. Based on the detailed investigation of biomass resource availability and demand, we can categorise the Uttara Kannada District into two zones (a) Biomass surplus zone consisting of Taluks mainly from hilly area (b) Biomass deficit zone, consisting of thickly populated coastal Taluks such as Bhatkal, Kumta, Ankola, Honnavar and Karwar. Fuel wood is mainly used for cooking and horticulture residues from coconut, arecanut trees are used for water heating purposes. Most of the households in this region still use traditional stoves where efficiency is less than 10%. The present inefficient fuel consumption could be brought down by the usage of fuel efficient stoves (a saving of the order of 27%). Availability of animal residues for biogas generation in Sirsi, Siddapur, Yellapur Taluks gives a viable alternative for cooking, lighting fuel and a useful fertiliser. However to support the present livestock population, fodder from agricultural residues is insufficient in these

  9. Regional energy projects in the Eurasian Area

    Full Text Available The Eurasian area has a very rich energy reserves, and is characterized by a complex network of relationships between major suppliers and consumers. The central place in this area has Russia as a country richest in energy resources in Eurasia. Beside her, the European Union is the largest economic and political grouping in the world, and a huge consumer of energy. The dynamic development of Chinese economy requires more energy imports by China. Dependence of the European Union and China on imported energy is high and will grow in the future. Russia is the world's dominant natural gas producer and one of the two largest oil producers in the world. Russia is the largest natural gas supplier of the EU and a significant oil and natural gas supplier of China. Energy projects in Eurasia are the result of the need to strengthen the stability of energy supplies, efforts to diversify sources of supply, and the geographic redistribution of Russian oil and gas exports. Although the interests of the main actors often do not agree, the reasons of energy security affect the development of joint energy projects.

  11. The Relationship Between Oil and Gas Industry Investment in Alternative Energy and Corporate Social Responsibility

    Konyushikhin, Maxim

    The U.S. Energy Information Administration forecasted energy consumption in the United States to increase approximately 19% between 2006 and 2030, or about 0.7% annually. The research problem addressed in this study was that the oil and gas industry's interest in alternative energy is contrary to its current business objectives and profit goals. The purpose of the quantitative study was to explore the relationship between oil and gas industry investments in alternative energy and corporate social responsibilities. Research questions addressed the relationship between alternative energy investment and corporate social responsibility, the role of oil and gas companies in alternative energy investment, and why these companies chose to invest in alternative energy sources. Systems theory was the conceptual framework, and data were collected from a sample of 25 companies drawn from the 28,000 companies in the oil and gas industry from 2004 to 2009. Multiple regression and correlation analysis were used to answer the research questions and test hypotheses using corporate financial data and company profiles related to alternative energy investment and corporate social responsibility in terms of oil and gas industry financial support of programs that serve the greater social good. Results indicated significant relationships between alternative energy investment and corporate social responsibility. With an increasing global population with energy requirements in excess of what is available using traditional means, the industry should increase investment in alternative sources. The research results may promote positive social change by increasing public awareness regarding the degree to which oil and gas companies invest in developing alternative energy sources, which might, in turn, inspire public pressure on companies in the oil and gas industry to pursue use of alternative energy.

    Studies have shown that the average North American family will spend more than a quarter of a million dollars on energy in a lifetime. What many other countries, including Germany, Spain, France, Denmark, China, Brazil, and even Iceland, have realized is that there is a better way to power our homes, businesses, and cars by using renewable energy sources. Recently, the United States has begun to understand the importance of reducing its reliance on coal, natural gas, nuclear power, and hydropower plants, which comprise the majority of the nation's electricity, due to increasing oil prices.

    Full Text Available It is well known, that the electrical energy storage in the large scale is basically difficult process. Such a process is marked by the energy losses, as the conversion of electrical energy into another form, is most frequently for example mechanical, and then back to the primary electrical form. Though, the superconducting magnetic energy storage (SMES technology offers the energy storage in an unchanged form, which is advantageous primarily in the achieved efficiency. Magnetic resonance imaging (MRI devices, commonly used in the medical facilities are based on the application of superconducting magnet. After its rejection from operation, there is possibility of using such devices for energy storage purposes. Additionally, such a technology of storage is also ecological.

  12. Coal, an alternative to nuclear power in Europe's energy future

    International Nuclear Information System (INIS)

    Paillard, Christophe-Alexandre

    2012-01-01

    The impending demise of nuclear power in several European countries and the projected strong increase in world energy requirements are placing coal in the forefront again. From being the primary energy source in the 19. century, coal is making a quite remarkable come-back in the 21. century with the advent of 'clean coal' and with its dominance in the energy mix of rapidly emerging countries such as China. New mines should open in Europe. In France, the last mine closed in 2004, but there is potential for new ones in the centre of France in areas such as Auvergne and Bourgogne, as well as Midi Pyrenees. These could create new jobs and reduce France's energy dependency. Far from the topical scenes of the past described in books such as Germinal, with its tips and misery, coal is again a promising energy source, with potential to satisfy a rising share of Europe's energy demand.

    ''Ecological cattle breeding: A climate killer''. This was the title of an article in ''Frankfurter Rundschau'' journal, which summarized the findings of a study according to which ecological cattle breeding is more harmful to the environment than conventional cattle breeding, not least because eco-cattle live longer and are kept according to the principles of organic farming. This special issue of OeKO-TEST goes into detail about ecological nutrition. After all, animal farming accounts for 18 percent of the global climate-relevant gaseous emissions. A closer look will show that ecological cattle breeding is not a climate killer but that ecological farming and nutrition may even help in the fight against global climate change. In fact, this has been known all along, as are other strategies to prevent global warming. Thirty years ago, the Oeko-Institut, Freiburg, published a concept to prevent global climate change that is still up to date. It comprises energy conservation, rational energy use, and the utilization of alternative energy sources. If these concepts had been followed then and there, we would not have the problems of global climate change and rising energy cost today. We all know how to save this planet and how to prevent the dying out of species, the pollution of the oceans and air, and the destruction of forests. It is up to us to do it. (orig.)

    Experiments using controlled manipulation of climate variables in the field are critical for developing and testing mechanistic models of ecosystem responses to climate change. Despite rapid changes in climate observed in many high latitude and high altitude environments, controlled manipulations in these remote regions have largely been limited to passive experimental methods with variable effects on environmental factors. In this study, we tested a method of controlled soil warming suitable for remote field locations that can be powered using alternative energy sources. The design was tested in high latitude, alpine tundra of southern Yukon Territory, Canada, in 2010 and 2011. Electrical warming probes were inserted vertically in the near-surface soil and powered with photovoltaics attached to a monitoring and control system. The warming manipulation achieved a stable target warming of 1.3 to 2 °C in 1 m(2) plots while minimizing disturbance to soil and vegetation. Active control of power output in the warming plots allowed the treatment to closely match spatial and temporal variations in soil temperature while optimizing system performance during periods of low power supply. Active soil heating with vertical electric probes powered by alternative energy is a viable option for remote sites and presents a low-disturbance option for soil warming experiments. This active heating design provides a valuable tool for examining the impacts of soil warming on ecosystem processes.

  18. Regional economic impact assessment: Evaluating remedial alternatives for the Portland Harbor Superfund Site, Portland, Oregon, USA.

    Harrison, David; Coughlin, Conor; Hogan, Dylan; Edwards, Deborah A; Smith, Benjamin C

    2018-01-01

    The present paper describes a methodology for evaluating impacts of Superfund remedial alternatives on the regional economy in the context of a broader sustainability evaluation. Although economic impact methodology is well established, some applications to Superfund remedial evaluation have created confusion because of seemingly contradictory results. This confusion arises from failure to be explicit about 2 opposing impacts of remediation expenditures: 1) positive regional impacts of spending additional money in the region and 2) negative regional impacts of the need to pay for the expenditures (and thus forgo other expenditures in the region). The present paper provides a template for economic impact assessment that takes both positive and negative impacts into account, thus providing comprehensive estimates of net impacts. The paper also provides a strategy for identifying and estimating major uncertainties in the net impacts. The recommended methodology was applied at the Portland Harbor Superfund Site, located along the Lower Willamette River in Portland, Oregon, USA. The US Environmental Protection Agency (USEPA) developed remedial alternatives that it estimated would cost up to several billion dollars, with construction durations possibly lasting decades. The economic study estimated regional economic impacts-measured in terms of gross regional product (GRP), personal income, population, and employment-for 5 of the USEPA alternatives relative to the "no further action" alternative.

  19. Total-factor energy efficiency of regions in China

    International Nuclear Information System (INIS)

    Hu, J.-L.; Wang, S.-C.

    2006-01-01

    This paper analyzes energy efficiencies of 29 administrative regions in China for the period 1995-2002 with a newly introduced index. Most existing studies of regional productivity and efficiency neglect energy inputs. We use the data envelopment analysis (DEA) to find the target energy input of each region in China at each particular year. The index of total-factor energy efficiency (TFEE) then divides the target energy input by the actual energy input. In our DEA model, labor, capital stock, energy consumption, and total sown area of farm crops used as a proxy of biomass energy are the four inputs and real GDP is the single output. The conventional energy productivity ratio regarded as a partial-factor energy efficiency index is computed for comparison in contrast to TFEE; our index is found fitting better to the real case. According to the TFEE index rankings, the central area of China has the worst energy efficiency and its total adjustmentof energy consumption amount is over half of China's total. Regional TFEE in China generally improved during the research period except for the western area. A U-shape relation between the area's TFEE and per capita income in the areas of China is found, confirming the scenario that energy efficiency eventually improves with economic growth

  20. Evaluation of alternative future energy scenarios for Brazil using an energy mix model

    Science.gov (United States)

    Coelho, Maysa Joppert

    The purpose of this study is to model and assess the performance and the emissions impacts of electric energy technologies in Brazil, based on selected economic scenarios, for a time frame of 40 years, taking the year of 1995 as a base year. A Base scenario has been developed, for each of three economic development projections, based upon a sectoral analysis. Data regarding the characteristics of over 300 end-use technologies and 400 energy conversion technologies have been collected. The stand-alone MARKAL technology-based energy-mix model, first developed at Brookhaven National Laboratory, was applied to a base case study and five alternative case studies, for each economic scenario. The alternative case studies are: (1) minimum increase in the thermoelectric contribution to the power production system of 20 percent after 2010; (2) extreme values for crude oil price; (3) minimum increase in the renewable technologies contribution to the power production system of 20 percent after 2010; (4) uncertainty on the cost of future renewable conversion technologies; and (5) model is forced to use the natural gas plants committed to be built in the country. Results such as the distribution of fuel used for power generation, electricity demand across economy sectors, total CO2 emissions from burning fossil fuels for power generation, shadow price (marginal cost) of technologies, and others, are evaluated and compared to the Base scenarios previous established. Among some key findings regarding the Brazilian energy system it may be inferred that: (1) diesel technologies are estimated to be the most cost-effective thermal technology in the country; (2) wind technology is estimated to be the most cost-effective technology to be used when a minimum share of renewables is imposed to the system; and (3) hydroelectric technologies present the highest cost/benefit relation among all conversion technologies considered. These results are subject to the limitations of key input

  2. Croatian Energy Policy as Function of Regional Development and Employment

    International Nuclear Information System (INIS)

    Potocnik, V.

    2006-01-01

    The Republic of Croatia has modest proven fossil fuels (oil and gas) reserves and relatively abundant renewable energy potential (wind, solar, biomass, geothermal, hydro), distributed mainly in less developed regions of Croatia. The Croatian energy system is excessively dependent on expensive oil and natural gas (80% of primary energy), compared to the European Union (61%), and the world average (58%). Approximately 60% of total energy is imported, which considerably contributes to the country's very high foreign trade deficit and foreign debt. Putting into focus of the Croatian energy policy the improvement of energy efficiency and implementation of renewable energies would significantly increase opportunities for mitigating rather wide regional development disparities and high unemployment rates, at the same time reducing energy import, foreign trade deficit and foreign debt, and contributing to energy security as a part of the national security.(author)

  3. Potential of building-scale alternative energy to alleviate risk from the future price of energy

    International Nuclear Information System (INIS)

    Bristow, David; Kennedy, Christopher A.

    2010-01-01

    The energy used for building operations, the associated greenhouse gas emissions, and the uncertainties in future price of natural gas and electricity can be a cause of concern for building owners and policy makers. In this work we explore the potential of building-scale alternative energy technologies to reduce demand and emissions while also shielding building owners from the risks associated with fluctuations in the price of natural gas and grid electricity. We analyze the monetary costs and benefits over the life cycle of five technologies (photovoltaic and wind electricity generation, solar air and water heating, and ground source heat pumps) over three audience or building types (homeowners, small businesses, large commercial and institutional entities). The analysis includes a Monte Carlo analysis to measure risk that can be compared to other investment opportunities. The results indicate that under government incentives and climate of Toronto, Canada, the returns are relatively high for small degrees of risks for a number of technologies. Ground source heat pumps prove to be exceptionally good investments in terms of their energy savings, emission, reductions, and economics, while the bigger buildings tend also to be better economic choices for the use of these technologies.

    Automakers have been mass producing hybrid electric vehicles (HEVs) for well over a decade, and the technology has proven to be very effective at reducing per-vehicle fuel use. However, the incremental cost of HEVs such as the Toyota Prius or Ford Fusion Hybrid remains several thousand dollars higher than the cost of comparable conventional vehicles, which has limited HEV market penetration. The b b b b battery energy storage device is typically the component with the greatest contribution toward this cost increment, so significant cost reductions/performance improvements to the energy storage system (ESS) can correspondingly improve the vehicle-level cost/benefit relationship. Such an improvement would in turn lead to larger HEV market penetration and greater aggregate fuel savings. The United States Advanced Battery Consortium (USABC) and the U.S. Department of Energy (DOE) Energy Storage Program managers asked the National Renewable Energy Laboratory (NREL) to collaborate with a USABC Workgroup and analyze the trade-offs between vehicle fuel economy and reducing the decade-old minimum energy requirement for power-assist HEVs. NREL’s analysis showed that significant fuel savings could still be delivered from an ESS with much lower energy storage than the previous targets, which prompted USABC to issue a new set of lower-energy ESS (LEESS) targets that could be satisfied by a variety of technologies. With support from DOE, NREL has developed an HEV test platform for in-vehicle performance and fuel economy validation testing of the hybrid system using such LEESS devices. This presentation describes development of the vehicle test platform, and laboratory as well as in-vehicle evaluation results with alternate energy storage configurations as compared to the production battery system. The alternate energy storage technologies considered include lithium-ion capacitors -- i.e., asymmetric electrochemical energy storage devices possessing one electrode with battery

    The policy instruments considered include: greater reliance on market forces; research and development; information, education and demonstration programs; tax incentives and sanctions; mortgage and finance programs; and regulations and standards. The analysis starts with an explanation of the barriers to energy conservation in the residential and commercial sectors. Individual policy instruments are described and evaluated with respect to energy conservation, economic efficiency, equity, political impacts, and implementation and other transitional impacts. Five possible strategies are identified: (1) increased reliance on the market place; (2) energy consumption tax and supply subsidies; (3) Building Energy Performance Standards (BEPS) with no sanctions and no incentives; (4) BEPS with sanctions and incentives (price control); and (5) BEPS with sanctions and incentives (no price controls). A comparative analysis is performed. Elements are proposed for inclusion in a comprehensive strategy for conservation in new buildings.

    A number of individuals and organizations advocate the use of comparative, formal analysis to determine which are the safest methods for producing and using energy. Some have suggested that the findings of such analyses should be the basis upon which final decisions are made about whether to actually deploy energy technologies. Some of those who support formal comparative analysis are in a position to shape the policy debate on energy and environment. An opposing viewpoint is presented, arguing that for technical reasons, analysis can provide no definitive or rationally credible answers to the question of overall safety. Analysis has not and cannot determine the sum total of damage to human welfare and ecological communities from energy technologies. Analysis has produced estimates of particular types of damage; however, it is impossible to make such estimates comparable and commensurate across different classes of technologies and environmental effects. As a result of the deficiencies, comparative analysis connot form the basis of a credible, viable energy policy. Yet, without formal comparative analysis, how can health, safety, and the natural environment be protected. This paper proposes a method for improving the Nation's approach to this problem. The proposal essentially is that health and the environment should be considered as constraints on the deployment of energy technologies, constraints that are embodied in Government regulations. Whichever technologies can function within these constraints should then compete among themselves. This competition should be based on market factors like cost and efficiency and on political factors like national security and the questions of equity

    The IEA was established about five years ago in the OECD immediately after the oil crisis, and 20 countries have participated in it. Progress was observed in the control of the expansion of energy demand. The energy utilization in IEA member countries became efficient due to the contribution of new technologies, and owing to the improvement of productivity, the growth of energy consumption was less than 1% despite the GDP grew at the yearly rate of 2.5%. The expansion of the utilization of natural gas and coal is promising, but the projects of nuclear power generation are behind schedule. The short term prospect in petroleum market is discussed, and the price of crude oil tends to be stabilized. ''The prospect of energy in the world by 2000'' will be published by the IEA in the latter half of 1980. The scale of the development of nuclear power generation was reduced because the prediction of the rate of power generation growth was changed from 5.2% to 3.1%. The effect of new energy technologies on future energy market has been studied by the support of 15 countries, and it was recommended to give financial aid to heat pumps, coal liquefaction and the efficient recovery of oil and natural gas. Also the techniques for operating existing facilities under strict environment and safety regulations have been studied. (Kako, I.)

    Using the panel data of 27 provinces between 1978 and 2008, we employed a instrumental regression technique to examine the relationship between economic growth, energy demand/production and the related policies in China. The empirical results show that forming a cross-province integrated energy market will in general reduce the response of equilibrium user costs of energy products to their local demand and production, through cross-regional energy transfer (including both energy trade and cross-regional reallocation). In particular, reducing transportation costs and improving marketization level are identified as two important policy instruments to enhance the role of energy market integration. The findings support the argument for a more competitive cross-province energy transfer policies and calls for more developed energy connectivity and associate institutional arrangements within China. These policy implications may also be extended to the East Asia Summit region where energy market integration is being actively promoted. - Highlights: • Development driving energy demand has different impacts on energy prices than others. • EMI will reduce the response of equilibrium energy prices to local demand and production. • Reducing transportation costs and improving marketization level enhance the role of EMI. • More market competition and better physical and institutional connectivity are better. • Policy implications to China may be extended to the East Asia Summit region

    The process of urbanization and the raise of living standards in China have led an increasing trend in the patterns of residential consumption. Projections for the population growth rate in urban areas do not paint a very optimistic picture for energy conservation policies. In addition, the concentration of economic activities around coastal areas calls for new prospects to be formulated for energy policy. In this context, the objective of this paper is twofold. First, we analyse the effect of the urbanization process of the Chinese economy in terms of the long-run patterns of residential energy consumption at national level. By using the concept of club convergence, we examine whether electricity and coal consumption in rural and urban areas converge to the same long-run equilibrium or whether in fact they diverge. Second, the impact of the regional concentration of the economic activity on energy consumption patterns is also assessed by source of energy across Chinese regions from 1995 to 2011. Our results suggest that the process of urbanization has led to coal being replaced by electricity in urban residential energy consumption. In rural areas, the evidence is mixed. The club convergence analysis confirms that rural and urban residential energy consumption converge to different steady-states. At the regional level, we also confirm the effect of the regional concentration of economic activity on residential energy consumption. The existence of these regional clusters converging to different equilibrium levels is indicative of the need of regional-tailored set of energy policies in China.

    The DOE Low-Level Waste Management Program has developed a computer-based decision support system of models that may be used by nonprogrammers to evaluate a comprehensive approach to commercial low-level radioactive waste (LLRW) management. REGINALT (Regional Waste Management Alternatives Analysis Model) implementation will be described as the model is applied to hypothetical regional compact for the purpose of examining the technical and economic potential of two waste processing alternatives. Using waste from a typical regional compact, two specific regional waste processing centers are compared for feasibility. Example 1 assumes that a regional supercompaction facility is being developed for the region. Example 2 assumes that a regional facility with both supercompaction and incineration is specified. Both examples include identical disposal facilities, except that capacity may differ due to variation in volume reduction achieved. The two examples are compared with regard to volume reduction achieved, estimated occupational exposure for the processing facilities, and life cycle costs per generated unit waste. A base case also illustrates current disposal practices. The results of the comparisons evaluated, and other steps, if necessary, for additional decision support are identified

    Highlights: • WTE plant is a reasonable and sustainable alternative technology to landfill. • A 150 kt plant in the only electrical configuration for Abruzzo region. • The percentage of energy recovery ranges from 21% to 25% in examined scenarios. • Financial Net Present Value is equal to 25.4 € per kiloton of treated waste. • The annual reduction of emissions is equal to 370 kgCO_2eq per ton of treated waste. - Abstract: The management of municipal solid waste (MSW) has been identified as one of the global challenges that must be carefully faced in order to achieve sustainability goals. European Union (EU) has defined as Waste to Energy (WTE) technology is able to create synergies with EU energy and climate policy, without compromising the achievement of higher reuse and recycling rates. The methodology used in this paper is based on two levels. A strategy analysis defines the amount of waste to incinerate with energy recovery considering different approaches based on unsorted waste, landfilled waste and separated collection rate, respectively. Consequently, it is evaluated the sustainability of a WTE plant as an alternative to landfill for a specific area. Two indicators are used: the Reduction of the Emissions of equivalent Carbon Dioxide (ER_C_O_2_e_q) and Financial Net Present Value (FNPV). Furthermore, a social analysis is conducted through interviews to identify the most critical elements determining the aversion toward the WTE realization. The obtained results show the opportunity to realize a 150 kt plant in the only electrical configuration. In fact, the cogenerative configuration reaches better environmental performances, but it is not profitable for this size. Profits are equal to 25.4 € per kiloton of treated waste and 370 kgCO_2eq per ton of treated waste are avoided using a WTE plant as an alternative to landfill. In this way, the percentage of energy recovery ranges from 21% to 25% in examined scenarios and disposal waste is minimised

    Building sector consumes a significant amount of energy worldwide (up to 40% of the total global energy); moreover, by the year 2030 the consumption is expected to increase by 50%. One of the reasons is that the performance of buildings and its components degrade over the years. In recent years, energy benchmarking for government office buildings, large scale public buildings and large commercial buildings is one of the key energy saving projects for promoting the development of building energy efficiency and sustainable energy savings in Gulf Cooperation Council (GCC) countries. Benchmarking would increase the purchase of energy efficient equipment, reducing energy bills, CO_2 emissions and conventional air pollution. This paper focuses on energy benchmarking for shopping centers in Gulf Coast Region. In addition, this paper will analyze a sample of shopping centers data in Gulf Coast Region (Dubai, Ajman, Sharjah, Oman and Bahrain). It aims to develop a benchmark for these shopping centers by highlighting the status of energy consumption performance. This research will support the sustainability movement in Gulf area through classifying the shopping centers into: Poor, Usual and Best Practices in terms of energy efficiency. According to the benchmarking analysis in this paper, the shopping centers best energy management practices in the Gulf Coast Region are the buildings that consume less than 810 kW h/m"2/yr, whereas the poor building practices are the centers that consume greater than 1439 kW h/m"2/yr. The conclusions of this work can be used as a reference for shopping centres benchmarking with similar climate. - Highlights: •The energy consumption data of shopping centers in Gulf Coast Region were gathered. •A benchmarking of energy consumption for the public areas for the shopping centers in the Gulf Coast Region was developed. •The shopping centers have the usual practice in the region between 810 kW h/m"2/yr and 1439 kW h/m"2/yr.

    2012-06-01

    The anticipated increase in variable generation in the Western Interconnection over the next several years has raised concerns about how to maintain system balance, especially in smaller Balancing Authority Areas (BAAs). Given renewable portfolio standards in the West, it is possible that more than 50 gigawatts of wind capacity will be installed by 2020. Significant quantities of solar generation are likely to be added as well. The consequent increase in variability and uncertainty that must be managed by the conventional generation fleet and responsive loads has resulted in a proposal for an Energy Imbalance Market (EIM). This paper extends prior work to estimate the reserve requirements for regulation, spinning, and non-spinning reserves with and without the EIM. We also discuss alternative approaches to allocating reserve requirements and show that some apparently attractive allocation methods have undesired consequences.

    Fast growing global energy needs raise concerns on energy supply security and climate change. Although policies addressing the two issues sometimes benefit one at the expense of the other, technology innovation, especially in alternative energy, provides a win–win solution to tackle both issues. This paper examines the effect of oil endowment on the patterns of technology innovation in the transportation sector, attempting to identify drivers of technology innovation in alternative energy. The analysis employs panel data constructed from patent data on five different types of automobile-related technologies from 1990 to 2002: oil extraction, petroleum refining, fuel cells, electric and hybrid vehicles (EHV) and vehicle energy efficiency. I find that countries with larger oil endowments perform less innovation on refining and alternative technologies. Conversely, higher gasoline prices positively impact the patent counts of alternative technologies and energy efficiency technology. The findings highlight the challenges and importance of policy designs in international climate change agreements. - Highlights: • I examine the effect of oil endowment on technology innovation in the transportation sector. • An empirical model was developed for a cross-country analysis of oil endowments. • A country's oil endowment is a negative driver of alternative technologies. • Energy price is a positive driver of alternative technologies and energy efficiency technology. • Implications for domestic and international climate policy are discussed

    The timely development of the nation's energy production capacity in a manner that minimizes potential adverse local and regional impacts associated with energy facilities requires the use of sophisticated techniques for evaluation of siting alternatives and fuel cycle options. This report is a documentation of the computerized SITE methodology that has been developed for evaluating health, environmental, and socioeconomic impacts related to utilization of alternate sites for energy production within a region of interest. The cost, impact, and attribute vectors, which are generated and displayed on density maps, can be used in a multiparameter overlay process to identify preferable siting areas. The assessment of clustered facilities in energy centers is also possible within the SITE analysis framework. An application of the SITE methodology to Northern Illinois is presented. Also included is a description of the ongoing extension of SITE for the accumulative evaluation of alternative regional energy siting patterns and fuel cycle options. An appendix provides documentation and user information for the SITE computer program

    2014-01-01

    Global warming is leading to a water resources decrease in the Mediterranean basin, where future farming resilience depends on incorporating alternative water sources and improving water-energy use efficiency. This paper assesses water and energy consumption when natural water sources are partially replaced by desalinated sea water. Initially, energy consumption, water supply and GHG (greenhouse gas) emissions were recorded for the current farming practices in SE (southeast) Spain. The results of our study indicate that citrus orchards have the lowest energy consumption and GHG emissions. Annual vegetables were the least energy efficient crops. Subsequently, two alternative water supply scenarios were analysed, in which the reduction of natural water resources associated to climate change was compensated with desalinated sea water. The use of 16.8% of desalinated seawater would increase energy consumption by 32.4% and GHG emissions by 19.6%, whereas for the use of 26.5% of desalinated seawater such increases would amount to 50.0% and 30.3%, respectively. Therefore maintaining irrigated agriculture in water-stressed regions by incorporating high energy demanding non-traditional water sources could negatively contribute to combat global warming. - Highlights: • Water supply, energy consumption and GHG (greenhouse gas) emissions in irrigated agriculture are very connected. • The use of desalinated sea water will increase the energy consumption, and GHG emissions will rise. • The use of non-traditional water resources enhances global warming processes. • Citrus orchards are the less sensitive crop to alternative water supplied scenarios. • Artichoke is the most sensitive crop to alternative water supplied scenarios

  3. Wind energy systems. Application to regional utilities

    1979-06-01

    This study developed a generic planning process that utilities can use to determine the feasibility of utilizing WECS (Wind Energy Conversion Systems) as part of their future mix of equipment. While this is primarily an economic process, other questions dealing with WECS availability, capacity credit, operating reserve, performance of WECS arrays, etc., had to be addressed. The approach was to establish the worth, or breakeven value, of WECS to the utility and to determine the impact that WECS additions would have on the utilities mix of conventional source.

    1990-01-01

    University of Pittsburgh physicist Cohen provides accessible, scientifically sound risk analyses of the energy options that he believes must be exercised in the next 10 years. This update of his work on public energy policy stands opposed to the stack of recent greenhouse effect-oriented titles by proposing more nuclear power plants (including fuel reprocessing plants) as statistically the safest, most environmentally sound solution. Cohen advances the debate on energy policy for all sides by first quantifying the human health costs of coal- and oil-generated electricity, and by debunking solar technology's deus ex machina role. In this context, Cohen looks at issues surrounding nuclear power since Three Mile Island, such as the "unsolved problem" of nuclear waste disposal and the "China Syndrome." Media people especially are urged to re-examine "nuclear hysteria" (no one ever writes about " deadly natural gas," Cohen notes), and even anti-nuclear activists will find the study's appendices and notes a sourceb...

    2014-01-01

    The disastrous effects of climate change as witnessed in recent violent storms, and the stark reality that fossil fuels are not going to last forever, is certain to create renewed demands for alternative energy sources. One such alternative source, namely solar energy, although unreliable because of its dependence on available sunlight, can nevertheless be utilised to generate a secondary source of energy, namely hydrogen, which can be stored and thereby provide a constant and reliable source of energy. The only draw-back with hydrogen, though, is finding efficient means for its storage. This study demonstrates how this problem can be overcome by the use of metal hydrides which offers a very compact and safe way of storing hydrogen. It also provides a case study of how solar and hydrogen energy can be combined in an energy system to provide an efficient source of energy that can be applied for modern technologies such as a mobile robot. Hydrogen energy holds out the most promise amongst the various alternative energy sources, so much so that it is proving to be the energy source of choice for automobile manufacturers in their quest for alternative fuels to power their cars of the future

    Water, energy, and food are the most important and fundamental resources for human beings and society. Demands for these resources are escalating rapidly because of increases in populations and changes in lifestyles. Therefore intensive demand for those resources makes conflicts between resources. Securities of water, energy, and food are treated separately, however they should be considered as one integrated matter, because water-energy-food are connected and it makes nexus and tradeoff. Security in terms of self-production, diversity of alternatives, and variability are evaluated for water, energy and food for thirty two countries in the Asia-Pacific region. The water and energy nexus includes water consumption for the cooling of power plant systems, water use for hydro power generation, and energy consumption for water allocation and pumping. The water and food nexus consists of water consumption for agriculture and aquaculture. The energy and food nexus includes energy consumption for food production and biomass for energy. Analyses of 11 countries within the Asia- Pacific region show that energy consumption for fish is the largest among foods in Japan, Philippines, and Peru, while energy consumption for cereals is the largest among foods in Canada, US, Indonesia, and others. Water consumption for different types of food and energy are also analyzed, including nexus ratio to total water consumption. The water-energy-food nexus at a local level in the Asia Pacific region are examined by the Research Institute for Humanity and Nature project "Human environmental security in Asia Pacific Ring of Fire". Themes including geothermal power plants for energy development and hot springs as water, shale gas for energy development and water consumption/contamination, aquaculture for food and water contamination are used to evaluate the water-energy-food nexus in the Asia-Pacific region.

    Phase I of this study analyzed attitudes and beliefs of respondents drawn from Metro Manila. The second phase utilized a sample drawn from residents near a geothermal power plant site in the Southern Philippines. Four dimensions of beliefs (psychological environmental risks, technological benefits/development, economic benefits/implications, and socio-political/implications/benefit) were identified through factor analysis of beliefs items on nuclear energy and refined empirically to determine perceptions of respondents about all other energy systems. Identification of the relationship between dimensions provided insight into the shared perceptions about each energy system held by the various groups of respondents. The overall attitude of the respondents towards energy systems (nuclear, solar, hydro, geothermal and oil) was determined using three attitude measures: the Fishbein model, Osgood's semantic differential technique, and direct response to unfavorability/favorability scale. The belief dimensions were correlated with the attitude measures to determine the degree of contribution to attitude. A comparative analysis was made to different attitudes and beliefs held by the PRO and CON nuclear groups and by the subsamples: university students, science teachers and barangay leaders of Metro Manila sample. Attitudes and beliefs relating to the demographic variables were also examined for the two samples. (author)

    The author describes the Point Lepreau nuclear power plant and its impact on the electric power grid and the economy of the small province of New Brunswick. The 600 MW CANDU reactor is considered suitable for small operations and has an excellent world record. Although nuclear energy has high capital costs, its fuel costs are low, thus rendering it comparatively inflation free. Its fuel costs of 3 to 4 mills are contrasted with 40 mills for oil-fuelled units. The cost advantage of uranium over coal and oil permits New Brunswick to put aside funds for waste management and decommissioning. Regulatory streamlining is needed to reduce both expense and time of construction. The CANDU system is ideally suited to providing base load, with coal as an intermediate load supply and hydro for peaking. There is room for tidal power as a future part of the mix

    2011-01-01

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

    This paper contributes to the existing literature as well as policy debates by examining energy intensity and its determinants in China's regional economies. The analysis is based on a comprehensive database of China's regional energy balance constructed for this project. Through its focus on regional China, this study extends the existing literature, which mainly covers nationwide studies. It is found in this paper that energy intensity declined substantially in China. The main contributing factor is the improvement in energy efficiency. Changes in the economic structure have so far affected energy intensity modestly. Thus there is considerable scope to reduce energy intensity through the structural transformation of the Chinese economy in the future. - Highlights: ► First study examining energy intensity and its determinants using sectoral data in Chinese regions. ► Major findings. ► Decline in energy intensity is due to the rise in energy efficiency. ► Economic structural change has played little role. ► Growth in capital intensity alone would not lead to the decline in energy consumption.

    Full Text Available The article shows that during the production and consumption of fuel wood for bioenergy projects in the organization of the Northwest and other regions of Russia there is the problem of lack of raw materials. It is established that the waste timber, during cutting on average, about 20% of the stock of standing timber. This value varies according to region, type forest resources and the skills, and technical equipment performer. Therefore, the main purpose of the article is a system evaluation of the use of forest residues in Russia. The authors present data on volumes of raw materials for production of wood chips and pellets on example, the Northwest region of Russia. Only about 30% of wood chips are now received from wood waste, bulk wood chips, and pellets produced from the wood of stems. Small volume of use of bark, twigs, branches, tops, stumps, and roots is due imperfection of processing technologies. Another important issue addressed in the article – the lack of standards and guides taxation inventory valuation and structure of the waste in many regions of Russia. This primarily relates to the hardwood. Research has shown that, depending on tree species, the structure and volume of waste are significantly different. Expert evaluation conducted by the authors shows that the proportion of forest residues from 5 to 20% of the stock of wood. It is found that in different forest types share twigs, branches, stumps, and roots vary considerably according to species of tree. But even within the forest reserves such as twigs, branches, and underground parts of the same species depend strongly on the age of stands and their completeness, and the differences may reach 2 to 5 times the size.

    During the last century, the average temperature of the earth has abnormally increased by 0.74 c, causing concern among scientists. Some experts believe that the earth has experienced the warmest years during the last decades of 20 century, to the extent that the last 400 years have been the warmest years. The reports 2007 suggest that the hottest periods recorded occur a 1990 - 2007 which was a record high during the past 150 years. It seems that industrialization has contributed significantly to the global warming. The measurement of earth temperature dates hack to 1880 which has continued up to the present time. It is also predicted that the year 2014 would witness an unprecedented high air temperature. Moreover, scientists have expressed grave concern about the occurrence of severe droughts, scorching heat and formidable storms which are yet to strike the earth in the year 2100. According to the I nternational atomic agency , nuclear energy is by far, the best and safest production source of electricity in the future due to it's low emission rate of carbon dioxide. However , prior to making any commitment, it seem imperative to increase public awareness about the dire consequences of the continued utilization of fossil fuels. Based on research carried out by International atomic agency, nuclear energy is superior to other sources of energy in two major respects: lack of any so-called greenhouse gas emission and the utilization of uranium as the single source the energy production. The study aims at first; probing into the causes of global warming, the outcomes and ultimately provision of a way out of the problem and identifying the means to seriously cope with the problem. 5

    Physics education researchers have scientifically established the fact that the understanding of new concepts and interpretation of incoming information are strongly influenced by the preexisting knowledge and beliefs of students, called epistemological beliefs. This can lead to a gap between what students actually learn and what the teacher expects them to learn. In a classroom, as a teacher, it is desirable that one tries to bridge this gap at least on the key concepts of a particular field which is being taught. One such key concept which crops up in statistical physics/solid-state physics courses, and around which the behaviour of materials is described, is Fermi energy (ε F ). In this paper, we present the results which emerged about misconceptions on Fermi energy in the process of administering a diagnostic tool called the Statistical Physics Concept Survey developed by the authors. It deals with eight themes of basic importance in learning undergraduate solid-state physics and statistical physics. The question items of the tool were put through well-established sequential processes: definition of themes, Delphi study, interview with students, drafting questions, administration, validity and reliability of the tool. The tool was administered to a group of undergraduate students and postgraduate students, in a pre-test and post-test design. In this paper, we have taken one of the themes i.e. Fermi energy of the diagnostic tool for our analysis and discussion. Students’ responses and reasoning comments given during interview were analysed. This analysis helped us to identify prevailing misconceptions/learning gaps among students on this topic. How spreadsheets can be effectively used to remove the identified misconceptions and help appreciate the finer nuances while visualizing the behaviour of the system around Fermi energy, normally sidestepped both by the teachers and learners, is also presented in this paper.

    Local actors at community level often thrive for energy autarky to decrease the dependence on imported energy resources. We assess the potentials and trade-offs between benefits and costs of increasing levels of energy autarky for a small rural region of around 21,000 inhabitants in Austria. We use a novel modeling approach which couples a regional energy system model with a regional land use optimization model. We have collected and processed data on the spatial distribution of energy demand and potentials of biomass, photovoltaics and solar thermal resources. The impacts of increasing biomass production on the agricultural sector are assessed with a land-use optimization model that allows deriving regional biomass supply curves. An energy system model is subsequently applied to find the least cost solution for supplying the region with energy resources. Model results indicate that fossil fuel use for heating can be replaced at low costs by increasing forestry and agricultural biomass production. However, autarky in the electricity and the heating sector would significantly increase biomass production and require a full use of the potentials of photovoltaics on roof tops. Attaining energy autarky implies high costs to consumers and a decline in the local production of food and feed. - Highlights: ► Energy autarky strong vision for many regional actors. ► Assessment of consequences of energy autarky for a rural region in Austria. ► Novel modeling approach coupling energy system model with land use model. ► Power and heat autarky causes high costs and decline in regional food and feed production. ► Heat autarky achievable at lower costs by utilizing regional forestry and agricultural biomass.

    Biomass plays an important and complex role in the lives of the people of rural Bangladesh, where more than 80 per cent of the country's population live. The problems relating to biomass do not have to do merely with the question of supply of wood, or of food or of fuel; the problems are linked to competition in the variegations of land-use and to differing end-uses of by-products that may compete with or complement each other. The paper discusses the present pattern and amount of biomass consumption with a view to assessing the future prospect of biomass supply in meeting various needs. Regarding biomass energy supply, several important conclusions can be drawn: a) the energy consumption pattern in Bangladesh is characterized by heavy dependence on traditional fuel; b) the domestic sector uses 80 per cent of the total biomass fuel and c) in the industrial sector, about 76 per cent of the energy used consists of biomass fuel, mainly for processing agricultural products. Several observations are made pertaining to different sectors of biomass fuel demand. (author)

    A novel membrane bioreactor (MBR) pilot system, using membrane reciprocation instead of air scouring, was operated at constant high flux and daily fluctuating flux to demonstrate its application under peak and diurnal flow conditions. Low and stable transmembrane pressure was achieved at 40 l/m(2)/h (LMH) by use of repetitive membrane reciprocation. The results reveal that the inertial forces acting on the membrane fibers effectively propel foulants from the membrane surface. Reciprocation of the hollow fiber membrane is beneficial for the constant removal of solids that may build up on the membrane surface and inside the membrane bundle. The membrane reciprocation in the reciprocating MBR pilot consumed less energy than coarse air scouring used in conventional MBR systems. Specific energy consumption for the membrane reciprocation was 0.072 kWh/m(3) permeate produced at 40 LMH flux, which is 75% less than for a conventional air scouring system as reported in literature without consideration of energy consumption for biological aeration (0.29 kWh/m(3)). The daily fluctuating flux test confirmed that the membrane reciprocation is effective to handle fluctuating flux up to 50 LMH. The pilot-scale reciprocating MBR system successfully demonstrated that fouling can be controlled via 0.43 Hz membrane reciprocation with 44 mm or higher amplitude.

    Energy, water, and land systems interact in many ways and are impacted by management and climate change. These systems and their interactions often differ in significant ways from region-to-region. To explore the coupled energy-water-land system and its relation to climate change and management a simple conceptual model of demand, endowment and technology (DET) is proposed. A consistent and comparable analysis framework is needed as climate change and resource management practices have the potential to impact each DET element, resource, and region differently. These linkages are further complicated by policy and trade agreements where endowments of one region are used to meet demands in another. This paper reviews the unique DET characteristics of land, energy and water resources across the United States. Analyses are conducted according to the eight geographic regions defined in the 2014 National Climate Assessment. Evident from the analyses are regional differences in resources endowments in land (strong East-West gradient in forest, cropland and desert), water (similar East-West gradient), and energy. Demands likewise vary regionally reflecting differences in population density and endowment (e.g., higher water use in West reflecting insufficient precipitation to support dryland farming). The effect of technology and policy are particularly evident in differences in the energy portfolios across the eight regions. Integrated analyses that account for the various spatial and temporal differences in regional energy, water and land systems are critical to informing effective policy requirements for future energy, climate and resource management.

    Full Text Available In this paper multiple criteria decision making approach of alternative fuels for waste collection vehicles in southeast region of Serbia was presented. Eight alternative fuels and advanced vehicle technologies were ranked according to thirteen criteria, including financial, socio-technical, and environmental. Assessment of alternatives was performed by using the weighted aggregated sum product assessment method and results were verified using multi-objective optimization on the basis of ratio analysis method. Considered criteria were obtained from previous researches and by assessment of professional experts from manufacturing industries, public utility companies, and academics institutions. The analysis showed that both biodiesel fuels - derived from used cooking oil or from vegetable oils are the best alternative fuels for Serbian waste collection vehicles in this point of time. Compressed natural gas-powered vehicles were also ranked high in this analysis, but due to the lack of financial capability for their purchase (especially in southeast region of Serbia, their gradual introduction into the waste collection fleet was proposed.

    Western prospectors are poised to go east, lured by the lucrative ore of electricity infrastructure. But increasingly, Asia is sending the message: Not For Sale.

    I. Project Summary Catalytic processes are a major technological underpinning of modern society, and are essential to the energy sector in the processing of chemical fuels from natural resources, fine chemicals synthesis, and energy conversion. Advances in catalyst technology are enormously valuable since these lead to reduced chemical waste, reduced energy loss, and reduced costs. New energy technologies, which are critical to future economic growth, are also heavily reliant on catalysts, including fuel cells and photo-electrochemical cells. Currently, the state of South Dakota is underdeveloped in terms of research infrastructure related to catalysis. If South Dakota intends to participate in significant economic growth opportunities that result from advances in catalyst technology, then this area of research needs to be made a high priority for investment. To this end, a focused research effort is proposed in which investigators from The University of South Dakota (USD) and The South Dakota School of Mines and Technology (SDSMT) will contribute to form the South Dakota Catalysis Group (SDCG). The multidisciplinary team of the (SDCG) include: (USD) Dan Engebretson, James Hoefelmeyer, Ranjit Koodali, and Grigoriy Sereda; (SDSMT) Phil Scott Ahrenkiel, Hao Fong, Jan Puszynski, Rajesh Shende, and Jacek Swiatkiewicz. The group is well suited to engage in a collaborative project due to the resources available within the existing programs. Activities within the SDCG will be monitored through an external committee consisting of three distinguished professors in chemistry. The committee will provide expert advice and recommendations to the SDCG. Advisory meetings in which committee members interact with South Dakota investigators will be accompanied by individual oral and poster presentations in a materials and catalysis symposium. The symposium will attract prominent scientists, and will enhance the visibility of research in the state of South Dakota. The SDCG requests

    The Western Area Power Administration (Western) was founded by the Department of Energy Organization Act of 1977 to market and transmit federal hydroelectric power in 15 western states outside the Pacific Northwest, which is served by the Bonneville Power Administration. Western is divided into four independent Customer Service Regions including the Sierra Nevada Region (Sierra Nevada), the focus of this report. The Central Valley Project (CVP) and the Washoe Project provide the primary power resources marketed by Sierra Nevada. Sierra Nevada also purchases and markets power generated by the Bonneville Power Administration, Pacific Gas and Electric (PG ampersand E), and various power pools. Sierra Nevada currently markets approximately 1,480 megawatts of power to 77 customers in northern and central California. These customers include investor-owned utilities, public utilities, government agencies, military bases, and irrigation districts. Methods and conclusions from an economic analysis are summarized concerning distributional effects of alternative actions that Sierra Nevada could take with it's new marketing plan

    In this report, we examine and compare how tradable mass-based polices and tradable rate-based policies create different incentives for energy efficiency investments. Through a generalized demonstration and set of examples, we show that as a result of the output subsidy they create, traditional rate-based policies, those that do not credit energy savings from efficiency measures, reduce the incentive for investment in energy efficiency measures relative to an optimally designed mass-based policy or equivalent carbon tax. We then show that this reduced incentive can be partially addressed by modifying the rate-based policy such that electricity savings from energy efficiency measures are treated as a source of zero-carbon generation within the framework of the standard, or equivalently, by assigning avoided emissions credit to the electricity savings at the rate of the intensity target. These approaches result in an extension of the output subsidy to efficiency measures and eliminate the distortion between supply-side and demand-side options for GHG emissions reduction. However, these approaches do not address electricity price distortions resulting from the output subsidy that also impact the value of efficiency measures. Next, we assess alternative approaches for crediting energy efficiency savings within the framework of a rate-based policy. Finally, we identify a number of challenges that arise in implementing a rate-based policy with efficiency crediting, including the requirement to develop robust estimates of electricity savings in order to assess compliance, and the requirement to track the regionality of the generation impacts of efficiency measures to account for their interstate effects.

    The introduction of alternative energy requires collaboration between consumers, energy suppliers and regulators. A fundamental question is, will consumers engage with this agenda and, in particular, will they trust the institutions sufficiently to enable the collaborations that are needed. Present indications suggest that consumers have little trust in the established institutions and tend to reject such collaborations. This article presents two case studies which explore the way consumers, regulators and energy suppliers interact in relation to alternative energy projects. It analyses the inter-group interactions from the perspective of symbolic interactionism and discusses the aspects that undermine trust, leading to suggestions for improved trust.

    The energy consumption in the Dalmatian region was estimated for residential and public sector, tourism, commercial sector and industry. The national energy program for the use of solar energy, SUNEN, assessed solar energy potential in Croatia. Energy from fossil fuels and electricity consumption in the region, which is mostly used in households for preparing hot water and space heating, could be economically substituted by renewable energy. The situation is most promising for the islands of the Adriatic, where solar thermal collectors, PV modules and wind generators could substitute conventional energy sources in satisfying the present thermal and electric demand. The Dalmatian Islands, characterised by a small density of energy consumption, are proposed as unique candidates in Europe for renewable zones, which could demonstrate the full potential of the renewable energy option. As a practical demonstration, the island of Lastovo and the planned tourist village and yacht marina in the Bay of Jurjeva Luka are proposed as a first solar demonstration project on the islands. Technical, economic, legal and institutional barriers, as well as shortages of financing the project identification process produced hereto an adverse environment for solar applications in Croatia. This paper is an initiative for eliminating the barriers and intensify the solar energy use in Croatia providing the clean environment and activation of indigenous energy resources in the region.

    Eighteen different alternative fuels were considered in the preliminary screening, from three basic resource bases. Coal can be used to provide 13 of the fuels; oil shale was the source for three of the fuels; and biomass provided the resource base for two fuels not provided from coal. In the case of biomass, six different fuels were considered. Nuclear power and direct solar radiation were also considered. The eight prime movers that were considered in the preliminary screening are boiler/steam turbine; open and closed cycle gas turbines; low and medium speed diesels; spark ignited and stratified charge Otto cycles; electric motor; Stirling engine; free piston; and fuel cell/electric motor. Modes of transport considered are pipeline, marine, railroad, and aircraft. Section 2 gives the overall summary and conclusions, the future outlook for each mode of transportation, and the R and D suggestions by mode of transportation. Section 3 covers the preliminary screening phase and includes a summary of the data base used. Section 4 presents the methodology used to select the fuels and prime movers for the detailed study. Sections 5 through 8 cover the detailed evaluation of the pipeline, marine, railroad, and aircraft modes of transportation. Section 9 covers the demand related issues.

    2005-01-01

    This paper aims at describing a novel constructive approach to develop decision support models to classify energy efficiency initiatives, including traditional Demand-Side Management and Market Transformation initiatives, overcoming the limitations and drawbacks of Cost-Benefit Analysis. A multicriteria approach based on the ELECTRE-TRI method is used, focusing on four perspectives: - an independent Agency with the aim of promoting energy efficiency; - Distribution-only utilities under a regulated framework; - the Regulator; - Supply companies in a competitive liberalized market. These perspectives were chosen after a system analysis of the decision situation regarding the implementation of energy efficiency initiatives, looking for the main roles and power relations, with the purpose of structuring the decision problem by identifying the actors, the decision makers, the decision paradigm, and the relevant criteria. The multicriteria models developed allow considering different kinds of impacts, but avoiding difficult measurements and unit conversions due to the nature of the multicriteria method chosen. The decision is then based on all the significant effects of the initiative, both positive and negative ones, including ancillary effects often forgotten in cost-benefit analysis. The ELECTRE-TRI, as most multicriteria methods, provides to the Decision Maker the ability of controlling the relevance each impact can have on the final decision. The decision support process encompasses a robustness analysis, which, together with a good documentation of the parameters supplied into the model, should support sound decisions. The models were tested with a set of real-world initiatives and compared with possible decisions based on Cost-Benefit analysis

    This regional public and planning document (SRCAE) first proposes a regional diagnosis in terms of energetic situation, climatic situation, air quality situation, building condition (in terms of energy), transports (characteristics of regional transport, of person and goods transport), industries and enterprises (important role of oil and chemical activities, low level of renewable and recovery energies), agriculture and forest, renewable energies (biomass and wastes, wind energy, solar photovoltaic, hydroelectricity, renewable heat production), and territory vulnerability in front of climate change. The second part states objectives and orientations: definition of scenarios, and of sector-based objectives (in the building, transport, agricultural, and industrial sectors, in the development of renewable energies, and in terms of adaptation to climate change). Synthetic approaches are then stated in relationship with different challenges related to sustainable behaviours and consumption, promotion of professions related to energy transition, diffusion of good practices in the fields of energy efficiency and emission reduction, sustainable land development, promotion of environmental mutations for the regional economy, innovation to face climate and energy challenges, development of renewable energies, anticipation of the adaptation to climate change, and SRCAE follow-up and assessment. Sheets of definitions of objectives are given for each sector. A synthetic version of this study is provided

    In this work, we explore some cosmological implications of the model proposed by M. Visser in 1998. In his approach, Visser intends to take into account mass for the graviton by means of an additional bimetric tensor in the Einstein's field equations. Our study has shown that a consistent cosmological model arises from the Visser's approach. The most interesting feature is that an accelerated expansion phase naturally emerges from the cosmological model, and we do not need to postulate any kind of dark energy to explain the current observational data for distant type Ia supernovae (SNIa).

    After a presentation and a brief comment of levels of final energy consumptions per sector and per energy source in Aquitaine in 2008, a first report proposes a brief overview of a Negawatt-type scenario for the region, a brief presentation of the notion of positive-energy territories, and a brief evocation of the role of smart grids and of energy storage. It discusses the role of the building sector by commenting some initiatives, objectives of building renovation and of thermal insulation of individual dwellings, and the development of positive-energy building. Then, it describes opportunities of a rational and combined development of renewable energies in the region. It more deeply discusses these opportunities for biomass (wood, methanization, bio-fuels), solar photovoltaic, geothermal, wind, and marine energies. For each of them, stakes, objectives, assets and arrangements for research and development, and current activities are presented. The report then addresses the issue of education and training for professions related to a green growth, the issue of financial engineering for these developments, and the issue of social innovation and acceptance as they are addressed at the regional level. A second document presents the regional approach (initiatives, tools and arrangements, examples) for a positive-energy territory

    This paper analyzes the output-energy relationship with alternative measures of output and energy. Our analysis rejects the hypothesis of non-diminishing returns to energy consumption when GDP at purchasing power parities is used as the output measure unlike the case with GNP at market exchange rates. This finding also holds when energy input includes the usage of both commercial and traditional fuels. 13 refs

  7. Promoting regional energy co-operation in South Asia

    2007-01-01

    Energy is a key ingredient of the socio-economic development of any region. South Asia is not only one of the fastest growing regions in the world; it is also one of the poorest, which thus puts energy at the very heart of the development process in the region. This paper looks at the challenges faced by the South Asia sub-region for economic co-operation (SASEC) comprised of Bangladesh, Bhutan, India and Nepal, and also at the role of greater regional energy co-operation therein. The region is characterized by pressures of growing economies and increasing population. While the per capita energy consumption is one of the lowest in the world, energy intensity continues to be very high. A large portion of the population lacks access to modern sources of energy and depends on traditional sources that are not only inefficient but also have severe health and environmental problems associated with them. Increasing oil import dependency and huge investment needs for energy market development pose a further challenge. The region has a good resource potential and tremendous scope for energy co-operation, which can play a key role in addressing many of these energy security concerns and in putting it on the path of sustainable development. It is ironic that the record in the area has been so limited and that too in the most basic form of co-operation, i.e. bilateral arrangements between countries. This paper puts forth a multi-pronged strategy for sub-regional energy co-operation encompassing softer options aimed at confidence building to more substantial and larger scale co-operation efforts. Delays in decision making to ensure stronger and mutually beneficial co-operation efforts are associated with high costs not only to the energy sector but also for the entire development agenda. With the precarious energy situation in the region and unprecedented increases in international oil prices seen in recent times, it is high time for policy makers, financing institutions, NGOs

    Full Text Available The problems of renewable energy and regional development have gained a global dimension, as well as the concerns about the economic growth. Therefore, this study investigates the issue of managing renewable energy in the EU10 region, within the context of recovery and anticipated growth of the region. The findings of this study disclose that an important source of economic growth in the EU10 region's countries may be to start some new investments in renewable energy. In order to develop the field of renewable energy may be used EU funds, and may be envisaged different public-private partnership models, that may contribute to lower societal costs and increased deployment rates. The study was conducted by combining a wide variety of sources, such as statistics, reports and articles. The results reported in this study could be used for further research in the area of implementing green energy projects in the EU10 region. Another direction for further research could be to identify the most attractive countries for different renewable energy investment projects in the EU10 region.

    2017-03-01

    Full Text Available For many countries and regions (both in Russia and abroad, natural resources are the crucial factor for socio-economic development. The role and significance of natural resources in the economy of different areas substantially depend on the institutional environment, including the resource regime. Today, we have a qualitative complication of conditions for mineral resources exploitation, we start to develop new, non-traditional types of resources, which haven’t been available (or demanded earlier for the economic and technological reasons. The changes in the characteristics of natural objects, as well as the increasing of uncertainty in the resource sector, actualize the search for alternatives of the development of resource-type regions and for the elaboration of appropriate strategies. In new conditions of resource regions, it is necessary to place emphasis on the aspects of expanded specific understanding of inclusiveness. It implies the possibility of active participation of regional authorities in the management and regulation of the mineral complex, as well as their involvement in the development of the association of a wide range of communities. These communities consist of the organizations representing the interests of indigenous peoples as well as professional communities: industry associations, environmental organizations, representatives of the innovation industry. Modern approaches to the elaboration of strategic directions for the resource regions development (primarily based on the development of the mineral industry should be based on sustainable development principles, the principles of inclusiveness and the need for innovations. As a result of the convergence of these characteristics, a new socio-economic concept is formed. This concept can be defined as the harmonious development that is extremely important for the Russian regions. The proposed approach can be used for the elaboration of strategic alternatives of the

  13. Essays on alternative energy policies affecting the US transportation sector

    Science.gov (United States)

    O'Rear, Eric G.

    This dissertation encompasses three essays evaluating the impacts of different policies targeting the greenhouse gas (GHG) emissions, fuel demands, etc. of the transportation sector. Though there are some similarities across the three chapters, each essay stands alone as an independent work. The 2010 US EPA MARKAL model is used in each essay to evaluate policy effects. Essay 1 focuses on the recent increases in Corporate Average Fuel Economy (CAFE) standards, and the implications of a "rebound effect." These increases are compared to a carbon tax generating similar reductions in system-wide emissions. As anticipated, the largest reductions in fuel use by light-duty vehicles (LDV) and emissions are achieved under CAFE. Consideration of the rebound effect does little to distort CAFE benefits. Our work validates many economists' belief that a carbon tax is a more efficient approach. However, because the tax takes advantage of cheaper abatement opportunities in other sectors, reductions in transportation emissions will be much lower than what we observe with CAFE. Essay 2 compares CAFE increases with what some economists suggest would be a much more "efficient" alternative -- a system-wide oil tax internalizing some environmental externalities. Because oil taxes are likely to be implemented in addition to CAFE standards, we consider a combined policy case reflecting this. Our supplementary analysis approximates the appropriate tax rates to produce similar reductions in oil demands as CAFE (CAFE-equivalent tax rates). We discover that taxes result in greater and more cost-effective reductions in system-wide emissions and net oil imports than CAFE. The current fuel tax system is compared to three versions of a national vehicle miles traveled (VMT) tax charged to all LDVs in Essay 3. VMT taxes directly charge motorists for each mile driven and help to correct the problem of eroding tax revenues given the failure of today's fuel taxes to adjust with inflation. Results

    2008-01-01

    Recent discussions at the Washington International Renewable Energy Conference (WIREC), hosted in March 2008 by the United States Government, with nearly 9000 participants including 103 ministers from 126 countries, concluded that a major acceleration in the adoption of renewable energy technologies was needed by mid-century. Because of different climatic conditions and societal preferences, regional cooperation is expected to play a major role in the efficient adoption of appropriate renewable energy technologies, and countries with special expertise in specific technologies seem eager to collaborate internationally to promote global goals in renewable energy. A review will be given of what we learned from this conference about renewable energy research and development strategies with a special focus given to using this basic knowledge base to promote the development of renewable energy technologies appropriate to specific regions of the world.(author)

    International Nuclear Information System (INIS)

    Charters, W.W.S.

    1996-01-01

    The interest shown by Asia in renewable energy technologies is currently extremely high as the region is expected to account for up to 50 percent of the total world power generation equipment orders over the next ten years. Mature developed technologies for power production from renewable energy resources are now available in the form of micro and mini hydro plants, biomass pyrolysis and gasification units, wind aerogenerators and photovoltaic arrays. If Australia is to move towards a sustainable energy society, renewable energy resources must be utilized on a widespread scale as soon as possible. There are large niche markets for renewable energy resource based equipment in Australia, as well as immense market opportunities in the neighbouring fast growing economies in Asia. Key issues to be addressed in terms of implementing major renewable energy programs in the region on a large scale include identification and encouragement of reliable markets, and mass production of high quality reliable products.

    The DOE Low-Level Waste Management Progam has developed a computer-based decision support system of models that may be used by nonprogrammers to evaluate a comprehensive approach to commercial low-level radioactive waste (LLRW) management. REGINALT (Regional Waste Management Alternatives Analysis Model) implementation will be described as the model is applied to a hypothetical regional compact for the purpose of examining the technical and economic potential of two waste processing alternaties. Using waste from a typical regional compact, two specific regional waste processing centers will be compared for feasibility. Example 1 will assume will assume that a regional supercompaction facility is being developed for the region. Example 2 will assume that a regional facility with both supercompation and incineration is specified. Both examples will include identical disposal facilities, except that capacity may differ due to variation in volume reduction achieved. The two examples will be compared with regard to volume reduction achieved, estimated occupational exposure for the processing facilities, and life cylcle costs per generated unit waste. A base case will also illustrate current disposal practices. The results of the comparisons will be evaluated, and other steps, if necessary, for additional decision support will be identified

    2012-09-04

    Since 1957, the International Atomic Energy Agency (IAEA) has worked to ensure the safe and responsible promotion of nuclear technology throughout the world. The IAEA operates at the intersection of the Nuclear Nonproliferation Treaty’s (NPT) fourth and third articles, which guarantee Parties to the Treaty the right to peaceful uses of nuclear technology, provided those activities are placed under safeguards verified by the IAEA. However, while the IAEA has enjoyed substantial success and prestige in the international community, there is a concern that its resources are being stretched to a point where it may no longer be possible to execute its multifaceted mission in its entirety. As noted by the Director General (DG) in 2008, demographics suggest that every aspect of the IAEA’s operations will be in higher demand due to increasing reliance on non-carbon-based energy and the concomitant nonproliferation, safety, and security risks that growth entails. In addition to these nuclear energy concerns, the demand for technical developmental assistance in the fields of food security, resource conservation, and human health is also predicted to increase as the rest of the world develops. Even with a 100% value-for-money rating by the U.S. Office of Management and Budget (OMB) and being described as an “extraordinary bargain” by the United Nations Secretary-General’s High-level Panel on Threats, Challenges and Change, real budget growth at the Agency has been limited to zero-real growth for a better part of the last two decades. Although the 2012 regular budget (RB) received a small increase for most programs, the 2013 RB has been set at zero-real growth. As a result, the IAEA has had to defer infrastructure investments, which has hindered its ability to provide the public goods its Members seek, decreased global security and development opportunities, and functionally transformed the IAEA into a charity, dependent on extrabudgetary (EB) contributions to sustain

  20. Ecological total-factor energy efficiency of regions in China

    Li Lanbing; Hu Jinli

    2012-01-01

    Most existing energy efficiency indices are computed without taking into account undesirable outputs such as CO 2 and SO 2 emissions. This paper computes the ecological total-factor energy efficiency (ETFEE) of 30 regions in China for the period 2005–2009 through the slack-based model (SBM) with undesirable outputs. We calculate the ETFEE index by comparing the target energy input obtained from SBM with undesirable outputs to the actual energy input. Findings show that China's regional ETFEE still remains a low level of around 0.600 and regional energy efficiency is overestimated by more than 0.100 when not looking at environmental impacts. China's regional energy efficiency is extremely unbalanced: the east area ranks first with the highest ETFEE of above 0.700, the northeast and central areas follow, and the west area has the lowest ETFEE of less than 0.500. A monotone increasing relation exists between the area's ETFEE and China's per capita GDP. The truncated regression model shows that the ratio of R and D expenditure to GDP and the degree of foreign dependence have positive impacts, whereas the ratio of the secondary industry to GDP and the ratio of government subsidies for industrial pollution treatment to GDP have negative effects, on the ETFEE. - Highlights: ► Most energy efficiency indices ignore undesirable outputs such as CO 2 and SO 2 emissions. ► The ecological total-factor energy efficiency (ETFEE) is computed by slack-based model (SBM). ► The datasets contains 30 regions in China for the period 2005–2009. ► China's regional energy efficiency is extremely unbalanced. ► A monotone increasing relation exists between ETFEE and per capita GDP.

    Jasper Degryse

    2017-04-01

    Full Text Available In fMRI research, one often aims to examine activation in specific functional regions of interest (fROIs. Current statistical methods tend to localize fROIs inconsistently, focusing on avoiding detection of false activation. Not missing true activation is however equally important in this context. In this study, we explored the potential of an alternative-based thresholding (ABT procedure, where evidence against the null hypothesis of no effect and evidence against a prespecified alternative hypothesis is measured to control both false positives and false negatives directly. The procedure was validated in the context of localizer tasks on simulated brain images and using a real data set of 100 runs per subject. Voxels categorized as active with ABT can be confidently included in the definition of the fROI, while inactive voxels can be confidently excluded. Additionally, the ABT method complements classic null hypothesis significance testing with valuable information by making a distinction between voxels that show evidence against both the null and alternative and voxels for which the alternative hypothesis cannot be rejected despite lack of evidence against the null.

    2016-01-01

    Owing to its strategic nature, the Spanish energy policy is primarily the responsibility of the central state. In spite of this, the Spanish legal code does in fact also confer certain powers to territorial governments in Spain, the Autonomous Communities. The objective of this work is specifically to investigate the differences between the energy performance of Spanish regions, which may be a consequence of specific features of their productive structures and resource endowments, in addition to the specific decisions adopted by each of them within the scope for action that they have in this area. With this aim in mind, we intend to calculate the inefficiency levels of Spanish regions as regards their use of various energy sources during the period 2003–2008, by estimating an environmental directional distance function. The results obtained confirm the existence of significant differences in the behaviour and evolution of regional energy efficiency and point to the need to pay more attention to energy planning in this territorial sphere. - Highlights: • Energy efficiency of Spanish regions by energy source is investigated. • The environmental directional distance function is used for the analysis. • Significant differences among regions in energy efficiency are observed. • Level of development and industrialization are not determinant to explain them.

    Yu, Sha; Eom, Jiyong; Evans, Meredydd; Clarke, Leon

    2014-01-01

    China is the second largest building energy user in the world, ranking first and third in residential and commercial energy consumption. Beginning in the early 1980s, the Chinese government has developed a variety of building energy codes to improve building energy efficiency and reduce total energy demand. This paper studies the impact of building energy codes on energy use and CO 2 emissions by using a detailed building energy model that represents four distinct climate zones each with three building types, nested in a long-term integrated assessment framework GCAM. An advanced building stock module, coupled with the building energy model, is developed to reflect the characteristics of future building stock and its interaction with the development of building energy codes in China. This paper also evaluates the impacts of building codes on building energy demand in the presence of economy-wide carbon policy. We find that building energy codes would reduce Chinese building energy use by 13–22% depending on building code scenarios, with a similar effect preserved even under the carbon policy. The impact of building energy codes shows regional and sectoral variation due to regionally differentiated responses of heating and cooling services to shell efficiency improvement. - Highlights: • We assessed long-term impacts of building codes and climate policy using GCAM. • Building energy codes would reduce Chinese building energy use by 13–22%. • The impacts of codes on building energy use vary by climate region and sub-sector

    International Nuclear Information System (INIS)

    Schaffer, Axel; Düvelmeyer, Claudia

    2016-01-01

    Bavaria's energy policy seeks to increase the share of power supply from renewable sources related to on-farm energy production (agricultural biogas, wind- and solar energy) from currently 15% to more than 30% in 2021. It is therefore of particular interest for policy-makers to identify regional drivers of and barriers to this concept. The presented study addresses this issue and applies a spatial regression analysis to Bavaria’s 71 rural counties. The findings indicate significant impacts of technological regional transformation ability, agricultural structure (degree of professionalization and consolidation of organic farming) and neighborhood effects. This is in contrast to most geographical factors, which seem to be of minor relevance. - Highlights: •Energy transition is largely carried by farmers’ adoption of renewable energy (RE). •Adoption of RE generally follows an s-shaped diffusion curve. •Drivers are regions’ transformation ability and professionalization of agriculture. •Adoption of RE conflicts with organic farming.

  19. Estimating the magnetic energy inside traveling compression regions

    Directory of Open Access Journals (Sweden)

    S. A. Kiehas

    2009-05-01

    Full Text Available We investigate a series of six TCRs (traveling compression regions, appearing in the course of a small substorm on 19 September 2001. Except for two of these TCRs, all Cluster spacecraft were located in the lobe and detected the typical signatures of TCRs, i.e., compressions in |B| and bipolar Bz variations. We use these perturbations in Bz for calculations on the magnetic energy inside the TCR and compare the amount of magnetic field energy with the kinetic energy inside the underlying plasma bulge. According to results obtained from theory, the amount of magnetic energy inside TCRs is about two times higher than the kinetic plasma energy inside the accompanied plasma bulge. We verify this theoretical result by first investigations of the magnetic field energy inside TCRs. The calculations lead to a magnetic energy in the order of 1010 Joule per RE for each of the TCRs.

    2013-01-01

    The manufacturing companies are one of the main consumers of energy. The increment in global warming and the instability in the petroleum oil market have motivated companies to find alternatives to reduce energy use. In the academic literature several researchers have demonstrated that optimization models can be successfully used to reduce energy use. This research presents the use of an optimization model to identify feasible economic alternatives to reduce energy use. The economic analysis methods used were the payback and the internal rate of return. The optimization model developed in this research was applied and validated using an electronic manufacturing company case study. The results demonstrate that the main variables affecting the economic feasibility of the alternatives are the economic analysis method and the initial implementation costs. Several scenarios were analyzed and the best results show that the manufacturing company could save up to $78,000 in three years if the recommendations based on the optimization model results are implemented. - Highlights: • Evaluate top consumers of energy in manufacturing: A/C, compressed air, and lighting • Economic analysis of alternatives to optimize energy used in manufacturing • Comparison of payback method and internal rate of return method with real data • Results demonstrate that the company could generate savings in energy use

    In support of more efficient utilization of clean energy generation sources, including renewable and nuclear options, HES (hybrid energy systems) can be designed and operated as FER (flexible energy resources) to meet both electrical and thermal energy needs in the electric grid and industrial sectors. These conceptual systems could effectively and economically be utilized, for example, to manage the increasing levels of dynamic variability and uncertainty introduced by VER (variable energy resources) such as renewable sources (e.g., wind, solar), distributed energy resources, demand response schemes, and modern energy demands (e.g., electric vehicles) with their ever changing usage patterns. HES typically integrate multiple energy inputs (e.g., nuclear and renewable generation) and multiple energy outputs (e.g., electricity, gasoline, fresh water) using complementary energy conversion processes. This paper reports a dynamic analysis of two realistic HES including a nuclear reactor as the main baseload heat generator and to assess the local (e.g., HES owners) and system (e.g., the electric grid) benefits attainable by their application in scenarios with multiple commodity production and high renewable penetration. It is performed for regional cases – not generic examples – based on available resources, existing infrastructure, and markets within the selected regions. This study also briefly addresses the computational capabilities developed to conduct such analyses. - Highlights: • Hybrids including renewables can operate as dispatchable flexible energy resources. • Nuclear energy can address high variability and uncertainty in energy systems. • Nuclear hybrids can reliably provide grid services over various time horizons. • Nuclear energy can provide operating reserves and grid inertia under high renewables. • Nuclear hybrids can greatly reduce GHG emissions and support grid and industry needs.

  3. Africa energy future: Alternative scenarios and their implications for sustainable development strategies

    International Nuclear Information System (INIS)

    Ouedraogo, Nadia S.

    2017-01-01

    The long-term forecasting of energy supply and demand is of prime importance in Africa due to the steady increase in energy requirements, the non-availability of sufficient resources, the high dependence on fossil-fuels to meet these requirements, and the global concerns over the energy-induced environmental issues. This paper is concerned with modelling possible future paths for Africa's energy future and the related emissions. Future energy demand is forecasted based on socio-economic variables such as gross domestic product, income per capita, population, and urbanisation. The Long-range Energy Alternative Planning System (LEAP) modelling framework is employed to analyse and project energy demand and the related emissions under alternative strategies for the period of 2010–2040. Results of scenarios including business-as-usual (BAU) policies, moderate energy access and accelerate energy access policies, renewable energies promotion and energy efficiency policies and their environmental implications are provided. The study provides some policy insights and identifies synergies and trade-offs relating to the potential for energy policies to promote universal energy access, enable a transition to renewable energy, and mitigate climate change for a sustainable development. - Highlights: • Possible future paths for Africa's energy future and the related emissions are modelled. • Scenarios using an adaptation of Schwartz's scenario approach, under LEAP are developed. • Under the current energy policies, the universal access to modern energy will not be met by 2030. • Policies to accelerate the changes in energy structure are required for sustainable development. • Investing in Energy efficient strategies has emerged as one of the best solution.

    2008-01-01

    This study computes the regional total-factor energy efficiency (TFEE) in Japan by employing the data envelopment analysis (DEA). A dataset of 47 prefectures in Japan for the period 1993-2003 is constructed. There are 14 inputs, including three production factors (labor employment, private, and public capital stocks) and 11 energy sources (electric power for commercial and industrial use, electric power for residential use, gasoline, kerosene, heavy oil, light oil, city gas, butane gas, propane gas, coal, and coke). GDP is the sole output. Following Fukao and Yue [2000. Regional factor inputs and convergence in Japan-how much can we apply closed economy neoclassical growth models? Economic Review 51, 136-151 (in Japanese)], data on private and public capital stocks are extended. All the nominal variables are transformed into real variables, taking into consideration the 1995 price level. For kerosene, gas oil, heavy oil, butane gas, coal, and coke, there are a few prefectures with TFEEs less than 0.7. The five most inefficient prefectures are Niigata, Wakayama, Hyogo, Chiba, and Yamaguchi. Inland regions and most regions along the Sea of Japan are efficient in energy use. Most of the inefficient prefectures that are developing mainly upon energy-intensive industries are located along the Pacific Belt Zone. A U-shaped relation similar to the environmental Kuznets curve (EKC) is discovered between energy efficiency and per capita income for the regions in Japan

  6. Modeling Aggregate Hourly Energy Consumption in a Regional Building Stock

    Directory of Open Access Journals (Sweden)

    2017-12-01

    Full Text Available Sound estimates of future heat and electricity demand with high temporal and spatial resolution are needed for energy system planning, grid design, and evaluating demand-side management options and polices on regional and national levels. In this study, smart meter data on electricity consumption in buildings are combined with cross-sectional building information to model hourly electricity consumption within the household and service sectors on a regional basis in Norway. The same modeling approach is applied to model aggregate hourly district heat consumption in three different consumer groups located in Oslo. A comparison of modeled and metered hourly energy consumption shows that hourly variations and aggregate consumption per county and year are reproduced well by the models. However, for some smaller regions, modeled annual electricity consumption is over- or underestimated by more than 20%. Our results indicate that the presented method is useful for modeling the current and future hourly energy consumption of a regional building stock, but that larger and more detailed training datasets are required to improve the models, and more detailed building stock statistics on regional level are needed to generate useful estimates on aggregate regional energy consumption.

    2008-12-15

    The overall aim of the NorWays project has been to provide decision support for the introduction of hydrogen as an energy carrier in the Norwegian energy system. The NorWays project is a research project funded by the Research Council of Norway. An important task has been to develop alternative scenarios and identifying market segments and regions of the Norwegian energy system where hydrogen may play a significant role. The main scenarios in the project have been: Reference: Based on the assumptions of World Energy Outlook with no new transport technologies; HyWays: Basic assumptions with technology costs (H{sub 2}) based on results from the HyWays project; No tax: No taxes on transport energy ('revenue neutral'); CO{sub 2} reduction: Reduced CO{sub 2} emissions by 75% in 2050. Three regional models have been developed and used to analyse the introduction of hydrogen as energy carrier in competition with other alternatives such as natural gas, electricity, district heating and bio fuels.The focus of the analysis has been on the transportation sector.

    2012-01-01

    This study presents a methodology to develop scenarios of evolution from 2010 to 2050, for energy consumption and emissions (CO 2 , HC, CO, NO x , PM) of the road transportation sector (light-duty and heavy-duty vehicles). The methodology is applied to Portugal and results are analyzed in a life-cycle perspective. A BAU trend and 5 additional scenarios are explored: Policy-based (Portuguese political targets considered); Liquid fuels-based (dependency on liquid fuels and no deployment of alternative refueling infrastructure); Diversified (introduction of a wide diversity of alternative vehicle technology/energy sources); Electricity vision (deployment of a wide spread electricity recharging infrastructure); Hydrogen pathway (a broad hydrogen refueling infrastructure is deployed). Total life-cycle energy consumption could decrease between 2 and 66% in 2050 relatively to 2010, while CO 2 emissions will decrease between 7 and 73% in 2050 relatively to 2010. In 2050 the BAU scenario remains 30% above the 1990 level for energy consumption and CO 2 emissions; the other considered scenarios lead to 4 to 29% reductions for energy consumption and 10 to 33% for CO 2 emissions in 2050 compared to the BAU. Therefore, alternative vehicle technologies are required in the long-term, but changes in taxation and alternative transportation modes policies are crucial for achieving short-term impacts. - Highlight: ► Assess future energy consumption and emissions scenarios for road transportation. ► LCA energy consumption could decrease 2 to 66% in 2050 relatively to 2010. ► Alternative vehicle technologies can help to lower the BAU scenario impacts. ► Different deployments of alternative technologies can lead to similar impacts.

  9. Mapping alternative energy paths for taiwan to reach a sustainable future: An application of the leap model

    Science.gov (United States)

    Chen, Wei-Ming

    Energy is the backbone of modern life which is highly related to national security, economic growth, and environmental protection. For Taiwan, a region having limited conventional energy resources but constructing economies and societies with high energy intensity, energy became the throat of national security and development. This dissertation explores energy solutions for Taiwan by constructing a sustainable and comprehensive energy planning framework (SCENE) and by simulating alternative energy pathways on the horizon to 2030. The Long-range Energy Alternatives Planning system (LEAP) is used as a platform for the energy simulation. The study models three scenarios based on the E4 (energy -- environment -- economic -- equity) perspectives. Three scenarios refer to the business-as-usual scenario (BAU), the government target scenario (GOV), and the renewable and efficiency scenario (REEE). The simulation results indicate that the most promising scenario for Taiwan is the REEE scenario, which aims to save 48.7 million tonnes of oil equivalent (Mtoe) of final energy consumption. It avoids USD 11.1 billion on electricity expenditure in final demand sectors. In addition, the cost of the REEE path is the lowest among all scenarios before 2020 in the electricity generation sector. In terms of global warming potential (GWP), the REEE scenario could reduce 35 percent of the GWP in the demand sectors, the lowest greenhouse gases emission in relation to all other scenarios. Based on lowest energy consumption, competitive cost, and least harm to the environment, the REEE scenario is the best option to achieve intergenerational equity. This dissertation proposes that promoting energy efficiency and utilizing renewable energy is the best strategy for Taiwan. For efficiency improvement, great energy saving potentials do exist in Taiwan so that Taiwan needs more ambitious targets, policies, and implementation mechanisms for energy efficiency enhancement to slow down and decrease

  10. Extracting Vegetation Coverage in Dry-hot Valley Regions Based on Alternating Angle Minimum Algorithm

    2017-07-01

    Vegetation coverage is one of the most important indicators for ecological environment change, and is also an effective index for the assessment of land degradation and desertification. The dry-hot valley regions have sparse surface vegetation, and the spectral information about the vegetation in such regions usually has a weak representation in remote sensing, so there are considerable limitations for applying the commonly-used vegetation index method to calculate the vegetation coverage in the dry-hot valley regions. Therefore, in this paper, Alternating Angle Minimum (AAM) algorithm of deterministic model is adopted for selective endmember for pixel unmixing of MODIS image in order to extract the vegetation coverage, and accuracy test is carried out by the use of the Landsat TM image over the same period. As shown by the results, in the dry-hot valley regions with sparse vegetation, AAM model has a high unmixing accuracy, and the extracted vegetation coverage is close to the actual situation, so it is promising to apply the AAM model to the extraction of vegetation coverage in the dry-hot valley regions.

    2016-06-01

    Full Text Available Alternative service delivery (ASD is generally confined to the provision opublic services within the boundaries of a single nation state. This paper extends thisconceptualization and practice beyond a single nation state by focusing on services provided  by international regional organizations (IROs, which encompass more than a single country. Recognizing that the regional approach may not be suitable under all circumstances, the papertakes a contingency approach and discusses with illustrations the conditions under which the regional or continental approaches may provide superior public services to the wider population. Three examples from the East African Community (EAC, Africa’s riparian river basins, and cross-border illicit trade of conflict minerals in the Great Lakes region are given as illustrative cases. Noting that Africa’s growing aspirations for inclusive development and rapid transformation call for better governance and quality public services, the paper ends by calling for more scholarly work and field experiments on ASD and other models applicable at local, national, regional and continental levels.

    2012-01-01

    We theoretically discuss X-ray absorption intensity in high-energy region far from the deepest core threshold to explain the morphology-dependent mass attenuation coefficient of some carbon systems, carbon nanotubes (CNTs), highly oriented pyrolytic graphite (HOPG) and fullerenes (C 60 ). The present theoretical approach is based on the many-body X-ray absorption theory including the intrinsic losses (shake-up losses). In the high-energy region the absorption coefficient has correction term dependent on the solid state effects given in terms of the polarization part of the screened Coulomb interaction W p . We also discuss the tail of the valence band X-ray absorption intensity. In the carbon systems C 2s contribution has some influence on the attenuation coefficient even in the high energy region at 20 keV.

    1979-05-01

    The crucial interrelationships of engineering manpower, technological innovation, productivity and capital re-formaton were keynoted. Near-term, a study has indicated a much larger New England energy demand-reduction/economic/market potential, with a probably larger engineering manpower requirement, for energy-conservation measures characterized by technological innovation and cost-effective capital services than for alternative energy-supply measures. Federal, regional, and state energy program responsibilities described a wide-ranging panorama of activities among many possible energy options which conveyed much endeavor without identifiable engineering manpower demand coefficients. Similarly, engineering manpower assessment data was described as uneven and unfocused to the energy program at the national level, disaggregated data as non-existent at the regional/state levels, although some qualitative inferences were drawn. A separate abstract was prepared for each of the 16 individual presentations for the DOE Energy Data Base (EDB); 14 of these were selected for Energy Abstracts for Policy Analysis (EAPA) and 2 for Energy Research Abstracts (ERA).

    Full Text Available The container gas transportation for low and medium level consumers as an alternative to pipelines is considered. The options for gas supply schemes, based on road and rail transport are given. The advantages and disadvantages of both types of gas transporting are described, the areas of their effective using are separated in the article. Promising implementations of technology in environment of economic crisis and also considering world trends of energy development are presented. The most advanced organization of compressed gas condensate transportation of unprepared gas fields in large diameter universal cylindrical balloons (up to 1000 mm are reasoned. The problem of compressed gas sea transportation are well disclosed, but the alternative ways of gas transportation by land are not investigated enough. Compressed Natural Gas (CNG Technology - is new promising technology for natural gas transportation by specially designed vessels – CNG-vessels. The feature of this technology is that natural gas can be downloaded directly near gas deposits and unloaded - directly into the customer's network. This eliminates significant capital investments in underwater pipelining or gas liquefaction plants. The main objects of investment are CNG-vessels themselves. The most attractive places for implementation of CNG-technology are sea (offshore natural gas deposits. Numerous international experts estimate the natural gas transportation by CNG-vessels in 1.5-2.0 times more cost-beneficial in comparison with offshore pipelines transportation, or in comparison with LNG (Liquefied Natural Gas shipping with natural gas transportation volume between 0.5 and 4.0 billion cubic meters per year on the route from 250 to 2,500 sea miles. This technology makes possible to provide gas supplement to the mountain and abounding in water areas, remote and weakly gasified regions. Described technology deserves special attention in the case of depleted and low-power oil and

    This paper discussed issues related to the use of alternate sources of energy in underground mining applications. Hydrogen power systems were examined in relation to operational drivers, available commercial supplies, site supplies, health and safety issues, capital and operating costs, mine production, and the role of government. Hydrogen power systems are being considered for mining applications in an effort to reduce greenhouse gas (GHG) emissions and reduce cooling and ventilation requirements. This article examined a range of issues that must be addressed before alternate energy systems such as hydrogen fuel cell technology can be used in larger-scale underground mining applications. The mining industry supports the development of new technologies. However, the introduction of alternate energy technologies must proceed in steps which include proof of concept testing, the development of generic infrastructure, power systems and regulations, and whole operating system studies. 13 refs., 1 fig.

    The dissemination of renewable alternative energy sources for electricity generation has always being done through regulatory mechanisms, created and managed by the government of each country. Since these sources are more costly to generate, they have received incentives in response to worldwide environmental concerns, above all with regard to the reduction of CO 2 emissions. In Brazil, the electricity generation from renewable alternative sources is experiencing a new phase of growth. Until a short time ago, environmental appeal was the strongest incentive to these sources in Brazil but it was insufficient to attain its objective. With the electricity crisis and the rationing imposed in 2001, another important factor gained awareness: the need to diversify energy sources. Within this context, this work has the objective of analyzing the regulatory mechanisms recently developed to stimulate electricity generation from renewable alternative energy sources in Brazil by following the experience of other countries such as the United States, United Kingdom and Germany

    Promoting the utilization of clean energy has been identified as one potential solution to addressing environmental pollution and achieving sustainable development in many countries around the world. Evaluating clean energy alternatives includes a requirement to balance multiple conflict criteria, including technology, environment, economy and society, all of which are incommensurate and interdependent. Traditional MCDM (multi-criteria decision making) methods, such as the weighted average method, often fail to aggregate such criteria consistently. In this paper, an improved MCDM method based on fuzzy measure and integral is developed and applied to evaluate four primary clean energy options for Jiangsu Province, China. The results confirm that the preferred clean energy option for Jiangsu is solar photovoltaic, followed by wind, biomass and finally nuclear. A sensitivity analysis is also conducted to evaluate the values of clean energy resources for Jiangsu. The ordered weighted average method is also applied to compare the method mentioned above in our empirical study. The results show that the improved MCDM method provides higher discrimination between alternative clean energy alternatives. - Highlights: • Interactions among evaluation criteria of clean energy resources are taken into account. • An improved multi-criteria decision making (MCDM) method is proposed based on entropy weight method, fuzzy measure and integral. • Clean energy resources of Jiangsu are evaluated with the improved MCDM method, and their ranks are identified.

    2009-11-01

    This study presents a methodology for estimating high-resolution, regional on-road vehicle emissions and the associated reductions in air pollutant emissions from vehicles that utilize alternative fuels or propulsion technologies. The fuels considered are gasoline, diesel, ethanol, biodiesel, compressed natural gas, hydrogen, and electricity. The technologies considered are internal combustion or compression engines, hybrids, fuel cell, and electric. Road link-based emission models are developed using modal fuel use and emission rates applied to facility- and speed-specific driving cycles. For an urban case study, passenger cars were found to be the largest sources of HC, CO, and CO(2) emissions, whereas trucks contributed the largest share of NO(x) emissions. When alternative fuel and propulsion technologies were introduced in the fleet at a modest market penetration level of 27%, their emission reductions were found to be 3-14%. Emissions for all pollutants generally decreased with an increase in the market share of alternative vehicle technologies. Turnover of the light duty fleet to newer Tier 2 vehicles reduced emissions of HC, CO, and NO(x) substantially. However, modest improvements in fuel economy may be offset by VMT growth and reductions in overall average speed.

    There is increasing concern in East Asia about regional cooperation in the field of nuclear power. At the APEC conference in Osaka in 1995, APEC (Asia Pacific Economic Cooperation) established an Energy Research Center. The center has started to perform joint research forecasts on energy supply and demand for the region. Japan proposed the inauguration of a Conference on Nuclear Safety in Asia at the Moscow Nuclear Energy Summit in 1996. The first conference was held in Tokyo that year. This year, the conference will be held in Seoul. Japan's Atomic Energy Commission sponsors the International Conference for Nuclear Cooperation in Asia every year. This year marks the eighth conference. The outstanding feature of this year's conference was that so many countries stressed regional cooperation. South Korea proposed the installation of a regional online radiation monitoring system. The Philippines asserted the need for a cooperative mechanism on the lines of ASIATOM. Why is so much concern now being focused on nuclear power cooperation in East Asia? What kind of regional cooperation is necessary, and what kind is possible? What are the unique features of nuclear power cooperation in East Asia? These are the points addressed in this paper. (author)

    2016-01-01

    Highlights: • Many companies providing energy services are experiencing difficulties. • This research identifies key activities for the provision of energy services. • Findings are aggregated to the business-model level providing managerial insights. • This research identifies two different business model innovation paths. • Energy companies may need to renew parts of, or the entire, business model. - Abstract: Energy services play a key role in increasing energy efficiency in the industry. The key actors in these services are the local and regional energy companies that are increasingly implementing energy services as part of their market offering and developing service portfolios. Although expectations for energy services have been high, progress has so far been limited, and many companies offering energy services, including energy companies, are experiencing difficulties in implementing energy services and providing them to the market. Overall, this research examines what is needed for local and regional energy companies to successfully implement energy services (and consequently provide them to the market). In doing this, a two-stage process is used: first, we identify key activities for the successful implementation of energy services, and second, we aggregate the findings to the business model level. This research demonstrates that to succeed in implementing energy services, an energy company may need to renew parts or all of its existing product-based business model, formulate a new business model, or develop coexisting multiple business models. By discussing two distinct business model innovation processes, this research demonstrates that there can be different paths to success.

    2011-01-01

    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.

    After a presentation of the studied territory, a recall of challenges related to climate change, a discussion of the role of Climate-Air-Energy Regional Schemes (SRCAE), this study reports an analysis of the territory vulnerability to climate change under different aspects (climate, biodiversity, water, agriculture, built environment, soil erosion, others). It draws the energy-climate profile of the region in terms of energy consumption and of vulnerability. These issues are then addressed per sector (housing, tertiary, agriculture, industry, transports, wastes, good consumption, tourism). Energy production is analysed (renewable energies, solar thermal, photovoltaic, wood, biomass, biogas, geothermal, combustion, bio-fuel). Scenarios are defined for energy saving, reduction of greenhouse gas emissions, renewable energy production, and carbon storage. An action plan is then defined. A second document reports studies of energy consumption, heritage, possibilities of development of renewable energies, and possibilities of development of positive energy building in the case of five communes (Fleurance, Gimont, Lectoure, Saint-Clar, and Samatan)

    The National Wildlife Refuge System Improvement Act of 1997 requires all units of the National Wildlife Refuge System to be managed under a Comprehensive Conservation Plan (CCP). The CCP must describe the desired future conditions of a refuge and provide long-range guidance and management direction to achieve refuge purposes. Charles M. Russell (CMR) National Wildlife Refuge, located in north-central Montana, is in the process of developing a range of management goals, objectives, and strategies for the CCP. The CCP for the Refuge must contain an analysis of expected effects associated with current and proposed refuge-management strategies. For refuge CCP planning, an economic analysis provides a means of estimating how current management (No Action Alternative) and proposed management activities (Alternatives) affect the local economy. This type of analysis provides two critical pieces of information: (1) it illustrates a refuge’s contribution to the local community; and (2) it can help in determining whether economic effects are or are not a real concern in choosing among management alternatives. It is important to note that the economic value of a refuge encompasses more than just the impacts on the regional economy. Refuges also provide substantial nonmarket values (values for items not exchanged in established markets) such as maintaining endangered species, preserving wetlands, educating future generations, and adding stability to the ecosystem (Carver and Caudill, 2007). However, quantifying these types of nonmarket values is beyond the scope of this study. This report first presents a description of the local community and economy near the Refuge. Next, the methods used to conduct a regional economic impact analysis are described. An analysis of the final CCP management strategies that could affect stakeholders and residents and the local economy is then presented. The refuge management activities of economic concern in this analysis are:

  13. Energy market integration and regional institutions in east Asia

    This article assesses the case made for energy market integration in East Asia by comparing the role of institutions in South East Asia and North East Asia. The types and functions of institutions and their overall structure are examined in light of global energy market trends. In South East Asia, the shift attempted by ASEAN towards more competitive markets is hampered by the remaining statist variants of the trade institution and bilateral energy diplomacy, which, as regards transaction cost functions, are sub-optimal. As for institutions with order-creating functions, the unresolved status of sovereignty within ASEAN hampers regulatory harmonisation; the great power management institution has since ASEAN's establishment reduced conflicts without providing decisive leadership conducive to integration. North East Asia's dependence on global energy markets overshadows the regional integration potential of the diverse liberalisation efforts and interconnection projects. Bilateral energy diplomacies, new trilateral institutions combined with ‘Track Two’ institutions and remaining great power competition co-exist. In both regions the institutional structure allows for step-wise, technical infrastructure integration. The environmental stewardship institution co-exists with statist energy security and development objectives while it supports cooperation on green energy. The overall structure of informal institutions constrains deeper energy market integration in several ways. - Highlights: • The structures of institutions explain East Asian energy market integration. • Transaction costs are increased by statist trade institutions and bilateralism. • Order-creating institutions are sub-optimal for energy market integration. • Multi-level great power management offers limited leadership for integration. • The environmental stewardship institution supports cooperation on green energy

    PTEN is one of the most frequently mutated genes in human cancer. It is known that PTEN has a wide range of biological functions beyond tumor suppression. Here, we report that PTENα, an N-terminally extended form of PTEN, functions in mitochondrial metabolism. Translation of PTENα is initiated from a CUG codon upstream of and in-frame with the coding region of canonical PTEN. Eukaryotic translation initiation factor 2A (eIF2A) controls PTENα translation, which requires a CUG-centered palindromic motif. We show that PTENα induces cytochrome c oxidase activity and ATP production in mitochondria. TALEN-mediated somatic deletion of PTENα impairs mitochondrial respiratory chain function. PTENα interacts with canonical PTEN to increase PINK1 protein levels and promote energy production. Our studies demonstrate the importance of eIF2A-mediated alternative translation for generation of protein diversity in eukaryotic systems and provide insights into the mechanism by which the PTEN family is involved in multiple cellular processes.

    The objective of this paper is to evaluate the long-run regional impacts of the tariff policy of the Brazilian electric power sector. This sector has undergone a reform process that started in the 1990s. Since the beginning of the reform, two spatial trends of distribution of electric power tariffs have emerged among the Brazilian states, one of convergence and another of spatial divergence. These trends have been guided by the new electric power tariff policy and by the spatial features of the Brazilian economy, which is marked by a high degree of spatial concentration and hierarchical distribution of large markets. In addition, because of the presence of strong economies of scale, the recent electric power prices differentials might be caused by differentials in market size that provide better conditions for the achievement of economies of scale for electric power utility companies located in larger markets. Given the role of electric power as an important intermediate input in the production process and the interdependence between sectors, an Energy Interregional Computable General Equilibrium model was used to simulate the long-run regional impacts of electric power tariff policy in Brazil. The simulations showed that the heterogeneity of energy-intensity and the differentials of energy substitution drive the spatial impacts of changes in electric power prices. On the other hand, the recent trend of spatial dispersion of electric power prices might contribute to a decrease in the long-run economic growth and to an increase in the regional inequalities in Brazil. - Highlights: ► We model the regional impacts of tariff policy of the electric power sector in Brazil. ► High electric power tariffs increases in regions with higher electric-power-intensity. ► Heterogeneity of energy supply determines an unequal pattern of energy substitution. ► Low possibilities of energy substitution generate the most negative economic impacts

    Full Text Available The present contribution intends to give an overview of the current -status of the energy crisis and suggest some sustainable alternatives for energy production. In first place, a brief summary of the history about resources for energy production is presented. The high dependency of fossil combustibles it is well known and has been estimated that more than 90% of the used energy comes from non-renewable resources such as oil, gas and carbon. In the same way, here, it is described that oil is, by far, the main source of energy used to date and as a consequence, this resource is, unavoidably,coming to an end and at the same time is causing and increasing environmental pollution problems. Later in this work, it is suggested that in order to achieve the energetic sustainability, the development of alternative sources that will allow the reduction of toxic greenhouse gas (GHG emissions as well as a decrease of water usage along with a decrease in the energy production costs are needed. One of the alternatives that have been proposed is the production of biofuels, such as biodiesel and bioethanol. Here, some of the main properties at the level of the employed raw materials and production systems are cited. Finally, this work suggests some solutions that are under development worldwide in order to face thiscurrent energy situation.

    This study proposes the lighting of the parking area and the surrounding streets of the north west part of the University Campus of Patras, using an alternative source of energy, the photovoltaic energy. The sizing of the proposed system results to a reliable, autonomous system which covers the total of the energy needs without any maintenance. Although the energy produced is more expensive compared to the grid electricity nowadays, such solutions seem necessary and well promising for the future as the fuel reserves are limited. (authors)

    A lot of human and natural resources have been put in the energy sector, but the quantity of supply to consumers is quite inadequate. To sustain industrial output and ensure rapid growth, there is a need for a reliable and efficient supply of energy. A survey was carried out to find out the knowledge of consumers on the use of solar energy as an alternative source of energy.The result indicated that although people are aware of existence, the product is not readily available for man
