    2006-01-01

    After a brief analysis of the history of global energy consumption, this paper discusses a plausible scenario of energy needs and related carbon emissions for the rest of the century. The global outlook and the probable evolution of several factors that impact on energy policy considerations - even on the local scale - demonstrate the great complexity and planetary dimension of the problems, as well as the almost certain sterility of out-of-context domestic energy-policy measures [it

    The Global Energy Assessment (GEA) brings together over 300 international researchers to provide an independent, scientifically based, integrated and policy-relevant analysis of current and emerging energy issues and options. It has been peer-reviewed anonymously by an additional 200 international experts. The GEA assesses the major global challenges for sustainable development and their linkages to energy; the technologies and resources available for providing energy services; future energy systems that address the major challenges; and the policies and other measures that are needed to realize transformational change toward sustainable energy futures. The GEA goes beyond existing studies on energy issues by presenting a comprehensive and integrated analysis of energy challenges, opportunities and strategies, for developing, industrialized and emerging economies. This volume is an invaluable resource for energy specialists and technologists in all sectors (academia, industry and government) as well as policymakers, development economists and practitioners in international organizations and national governments.

  3. Global perspectives on future nuclear energy utilisation

    This paper is presented as an overview of the nuclear sector from a global perspective. The aim is to show that nuclear power does have a future but that this will only be fully realised when the industry is able to demonstrate that it is part of the solution to the world's energy and environmental difficulties rather than part of the problem. The paper looks at the projected world energy demand as the population increases and countries develop, showing that nuclear power is required to meet this demand. In presenting nuclear power as a solution, the paper addresses the challenges facing us such as public confidence, environmental opposition, political issues and finance. It addresses the debate over reprocessing and direct disposal of irradiated nuclear fuel and looks at the competition from other fuels. The paper suggests how the industry might approach these issues such that nuclear power is indeed regarded globally as a solution to some of the worlds most pressing problems. (author)

    Inclusion of renewable energy sources in national and international energy strategies is a key component of a viable global energy future. The global energy balance is going to shift radically in the near future brought about by significant increases in population in China and India, and increases in the energy intensity of developing countries. To better understand the consequences of such global shifts in energy requirements and to develop appropriate energy strategies to respond to these shifts, we need to look at the factors driving choices among supply options by geopolitical consumers and the impact these factors can have on the future energy mix.

    Highlights: • Integrated assessment model perform a series of scenarios of technology advances. • Explore the potential roles of wind energy technology advance in global energy. • Technology advance impacts on energy consumption and global low carbon market. • Technology advance influences on global energy security and stability. - Abstract: To avoid additional global warming and environmental damage, energy systems need to rely on the use of low carbon technologies like wind energy. However, supply uncertainties, production costs, and energy security are the main factors considered by the global economies when reshaping their energy systems. Here, we explore the potential roles of wind energy technology advancement in future global electricity generations, costs, and energy security. We use an integrated assessment model performing a series of technology advancement scenarios. The results show that double of the capital cost reduction causes 40% of generation increase and 10% of cost ​decrease on average in the long-term global wind electricity market. Today’s technology advancement could bring us the benefit of increasing electricity production in the future 40–50 years, and decreasing electricity cost in the future 90–100 years. The technology advancement of wind energy can help to keep global energy security and stability. An aggressive development and deployment of wind energy could in the long-term avoid 1/3 of gas and 1/28 of coal burned, and keep 1/2 biomass and 1/20 nuclear fuel saved from the global electricity system. The key is that wind resources are free and carbon-free. The results of this study are useful in broad coverage ranges from innovative technologies and systems of renewable energy to the economic industrial and domestic use of energy with no or minor impact on the environment.

    Climate models provide the principal means of projecting global warming over the remainder of the twenty-first century but modelled estimates of warming vary by a factor of approximately two even under the same radiative forcing scenarios. Across-model relationships between currently observable attributes of the climate system and the simulated magnitude of future warming have the potential to inform projections. Here we show that robust across-model relationships exist between the global spatial patterns of several fundamental attributes of Earth's top-of-atmosphere energy budget and the magnitude of projected global warming. When we constrain the model projections with observations, we obtain greater means and narrower ranges of future global warming across the major radiative forcing scenarios, in general. In particular, we find that the observationally informed warming projection for the end of the twenty-first century for the steepest radiative forcing scenario is about 15 per cent warmer (+0.5 degrees Celsius) with a reduction of about a third in the two-standard-deviation spread (-1.2 degrees Celsius) relative to the raw model projections reported by the Intergovernmental Panel on Climate Change. Our results suggest that achieving any given global temperature stabilization target will require steeper greenhouse gas emissions reductions than previously calculated.

    An extension in the use of energy, on even a fairly moderate basis, will, for several decades at least, require the use of all our present energy sources at rates that are a natural extension of historical rates, trending toward maximum practicable exploitation for all but nuclear energy. Regardless of what happens with the fossil hydrocarbons nuclear energy will play a major role in the supply of energy. When the fossil hydrocarbons have run their course nuclear and possibly some solar energy, through the media of electricity, hydrogen and synthetic hydrocarbons, will provide the bulk of the world's controlled energy and in sufficient quantity to provide ample energy for all. The burning question, however, is what will happen in the next few decades. There is a wonderful opportunity for nuclear energy, as the world requirement for energy, and particularly electrical energy, grows

    The first version of REN21's Renewables Global Futures Report (GFR) published in January 2013 identified a panorama of likely future debates related to the renewable energy transition. As a reflection of the wide range of contemporary thinking by the many experts interviewed for the report, it did not present just one vision of the future but rather a 'mosaic' of insights. Given the positive feedback in response to the first edition, a new edition has been prepared, continuing where the last one left off. The objective of this report is to gather opinions about the feasibility of a 100% renewable energy future, and the macro-economic impacts it would entail. In so doing, the report reflects on the debates of 2013, and tracks their evolution to the present time. Some remain, some have changed, some have been overtaken by progress, and new ones have arisen. They are summarised here as the Great Debates in renewable energy. The questionnaire for the survey was developed in close cooperation between the REN21 Secretariat, the Institute for Sustainable Future (ISF) of the University of Technology Sydney/Australia (UTS) and the Institute for Advanced Sustainability Studies (IASS) in Potsdam/Germany. It covered the following topics: 1. How much renewables?; 2. Power sector; 3. Heating and cooling; 4. Transport; 5. Storage; 6. Demand-side management and energy efficiency; 7. Integration of sectors; 8. Macro-economic considerations; 9. Technology and costs; 10. Policy; 11. Cities; 12. Distributed renewable energy/energy access; 13. Barriers/challenges/enablers. 114 experts were interviewed in total; the average interview time was approximately one hour. The interviews were conducted between May and October 2016. The questionnaire was also mirrored in an online version and used both by interviewers and interviewees to record the interview process. Interviewees were selected from the following regions: Africa, Australia and Oceania, China, Europe, India, Japan, Latin America

    Among the many disputes in the field of energy, in many countries none appear to be as acrimonious as those surrounding nuclear power. Its supporters are confident that nuclear power will have an important long-term future on the global energy scene, while its critics are equally confident that its days are numbered and that it was only developed to provide a political fig-leaf for a nuclear weapons programme. Both sides believe the other to be thoroughly biased or stupid and there is little constructive debate between them. As the disputes rage, especially over such issues as the management of nuclear waste, the economics and safety of nuclear power compared with other sources of electricity, the possible links with nuclear weapons and the attitude of the public towards the industry, decision-making is either paralysed or dominated by those who shout loudest. As a result, governments, industry and the financial sector have in recent years found it increasingly difficult to develop policy in this field. Deciding about future energy developments requires balanced and trustworthy information about issues such as the relative environmental effects of different options, the safety of installations, economics and the availability of resources. This is of particular importance now because world energy use is expected to continue to grow significantly during this century, particularly in less developed countries. In the same period, global emissions of greenhouse gases, especially carbon dioxide, will have to be severely curbed. To meet both these requirements may well involve a step change away from being able to meet growing energy needs by depending on an ever increasing supply of carboniferous fossil fuel. To address this situation, the Royal Institute of International Affairs undertook a two-year research project, aimed at providing information from the standpoint of an organization with no vested interest in either the pro or the anti camp, but close connections to

    The objective of this study has been to evaluate the possibilities of some new energy sources (solar, wind) in the future world energy supply. We intend to prepare future projections accounting for limitations in infrastructure, time and material inputs. One underlying assumption in the analyses is that new technologies will see an early market introduction in the near future which would continue up to year 2020. During these 30 years, there will still be technological developments leading to a much better manufacturability, mass production, and hence reduced costs. In year 2020, the industrial and economic infrastructure of new energy sources would be mature for a major penetration into the world energy market starting to substitute existing energy sources mainly for environmental reasons. This scenario will be suported by more factual information and data in the following chapters. Each new energy technology will be handled separately. (Quittner)

    The article deals with ethical questions regarding a future global energy supply by considering the normative aspects of economic efficiency, long-term liabilities, environmental sustainability, social acceptability and distributive equity. Regarding the ethical issues dealt with in the debate on the global energy supply, in particular two postulates arise: Both an improvement in knowledge and an improvement in the categories and procedures of ethical reflection are required.

    This paper explores the relationship between measures of human well-being and consumption of energy and electricity. A correlation is shown between the United Nations Human Development Index (HDI) and annual per- capita electricity consumption for 60 populous countries comprising 90% of the world population. In this correlation, HDI reaches a maximum value when electricity consumption is about 4,000 kWh per person per year, well below consumption levels for most developed countries but also well above the level for developing countries. The correlation with electricity use is better than with total primary energy use. Global electricity consumption associated with a ''Human Development Scenario'' is estimated by adding to U.S. Department of Energy projections for the year 2020 increments of additional electricity consumption sufficient to reach 4,000 kWh per capita on a country-by-country basis. A roughly constant ratio of primary energy consumption to electric energy consumption is observed for countries with high levels of electricity use, and this ratio is used to estimate global primary energy consumption in the Human Development Scenario. The Human Development Scenario implies significantly greater global consumption of electricity and primary energy than do projections for 2020 by the DOE and others. (author)

    A global energy, economics, environment (E 3 ) model has been adopted and modified with a simplified, but comprehensive and multi-regional, nuclear energy module. Using this model, consistent nuclear energy scenarios are constructed. A spectrum of future is examined at two levels in a hierarchy of scenario attributes in which drivers are either external or internal to nuclear energy. Impacts of a range of nuclear fuel-cycle scenarios are reflected back to the higher-level scenario attributes. An emphasis is placed on nuclear materials inventories (in magnitude, location, and form) and their contribution to the long-term sustainability of nuclear energy and the future competitiveness of both conventional and advanced nuclear reactors

    The Global Climate and Energy Project (GCEP), at Stanford University, invests in research with the potential to lead to energy technologies with lower greenhouse gas emissions than current energy technologies. GCEP is sponsored by four international companies, ExxonMobil, GE, Schlumberger, and Toyota and supports research programs in academic institutions worldwide. Research falls into the broad areas of carbon based energy systems, renewables, electrochemistry, and the electric grid. Within these areas research efforts are underway that are aimed at achieving break-throughs and innovations that greatly improve efficiency, performance, functionality and cost of many potential energy technologies of the future including solar, batteries, fuel cells, biofuels, hydrogen storage and carbon capture and storage. This paper presents a summary of some of GCEP's activities over the past 7 years with current research areas of interest and potential research directions in the near future.

    Global energy consumption in the last half century has rapidly increased and is expected to continue to grow over the next 50 years, however, with significant differences. The past increase was stimulated by relatively "cheap" fossil fuels and increased rates of industrialization in North America, Europe and Japan; yet while energy consumption in these countries continues to increase, additional factors make the picture for the next 50 years more complex. These additional complicating factors include China and India's rapid increase in energy use as they represent about a third of the world's population; the expected depletion of oil resources in the near future; and, the effect of human activities on global climate change. On the positive side, the renewable energy (RE) technologies of wind, bio-fuels, solar thermal and photovoltaics (PV) are finally showing maturity and the ultimate promise of cost competitiveness.

    Toward the future, the petroleum could stop to be the main energy source in the world and the oil companies will only survive if they are adjusted to the new winds that blow in the general energy sector. It will no longer be enough to be the owner of the resource (petroleum or gas) so that a company subsists and be profitable in the long term. The future, it will depend in great measure of the vision with which the oil companies face the globalization concept that begins to experience the world in the energy sector. Concepts like globalization, competition, integration and diversification is something that the companies of the hydrocarbons sector will have very present. Globalization means that it should be been attentive to what happens in the world, beyond of the limits of its territory, or to be caught by competitive surprises that can originate in very distant places. The search of cleaner and friendlier energy sources with the means it is not the only threat that it should fear the petroleum. Their substitution for electricity in the big projects of massive transport, the technology of the communications, the optic fiber and the same relationships with the aboriginal communities are aspects that also compete with the future of the petroleum

    The energy world is in rapid evolution, driven in particular by policy developments (like the INDCs agreed at COP-21) but also economic, geopolitical, technological as well as social considerations. Enerdata regularly produces scenario based energy outlooks to analyze and forecast the supply and demand of energy commodities, energy prices, as well as the impact of climate change and energy policies on energy markets and their consequences for the energy industry. After the COP-21 in Paris, Enerdata has again done such an exercise. The Ener-Blue scenario provides an outlook of energy systems up to 2040 based on the achievement of the 2030 targets defined in the INDCs as announced at the COP-21. Ener-Green explores the implications of more stringent energy and climate policies to limit the global temperature increase at around 1.5-2 deg. C by the end of the century. Finally, Ener-Brown describes a world with abundant fossil fuel resource and durably low energy prices, affecting the entire energy system over a long period. These different scenarios explore the consequences on energy supply and demand, energy mix, energy prices by fuel and region, as well as the implications on climate issues. In the Ener-Blue scenario, the future energy mix remains dominated by fossil fuels, but INDCs planned policies regarding climate mitigation, energy efficiency and renewable energy sources lead to a diversification towards other sources of energy. Among others, the EU successfully achieves its triple objective of its climate and energy package, while China and India expand their renewable capacities to achieve their renewable targets. Within this international context of climate coordinated policies, CO_2 emission growth slows down. However, the efforts defined in INDCs are not ambitious enough to limit the increase of the average global temperature to 2 deg. C in 2050, but these efforts are compatible with 3-4 deg. C objective. In the Ener-Green scenario, there is a clear

    The world's future energy needs will require a mix of energy conversion technologies matched to the local energy market needs while also responding to both local and global socio-political concerns, e.g. energy security, environmental impact, safety and non-proliferation. There is growing recognition worldwide that nuclear energy should not only be part of the solution but maybe as well play a larger share in future's energy supply. The sustainability of future nuclear energy systems is hereby important and a variety of studies have already shown that sustainability of nuclear energy from a resource perspective is achievable via the nuclear fuel cycle though where economic sustainability is essentially defined by the nuclear power plants. The main challenge in deploying sustainable nuclear energy systems will be to find synergies between this local competitiveness of nuclear power plants and the global resource sustainability defined via the nuclear fuel cycle. Both may go hand-in-hand in the long-term but may need government guidance in starting the transition towards such future sustainable nuclear energy systems. (authors)

    Full Text Available This paper presents a futures study of international forest trends. The study, produced as part of the Swedish Future Forest program, focuses on global changes of importance for future Swedish forest use. It is based on previous international research, policy documents, and 24 interviews with selected key experts and/or actors related to the forest sector, and its findings will provide a basis for future research priorities. The forest sector, here defined as the economic, social, and cultural contributions to life and human welfare derived from forest and forest-based activities, faces major change. Four areas stand out as particularly important: changing energy systems, emerging international climate policies, changing governance systems, and shifting global land use systems. We argue that global developments are, and will be, important for future Swedish forest use. The forest sector is in transition and forest-, energy, climate- and global land use issues are likely to become increasingly intertwined. Therefore, the “forest sector” must be disembedded and approached as an open system in interplay with other systems.

    Human society entered into the society of large energy consumption since the industrial revolution and consumes more than 10 billion tons of oil equivalent energy a year in the world in the present time, in which over 80% is provided by fossil fuels such as coal, oil and natural gas. Total energy consumption is foreseen to increase year by year from now on due to significant economical and population growth in the developing countries such as China and India. However, fossil fuel resources are limited with conventional crude oil estimated to last about 40 years, and it is said that the peak oil production time has come now. On the other hand, global warming due to green house gases (GHG) emissions, especially carbon dioxide, has become a serious issue. Nuclear energy plays an important role as means to resolve energy security and global warming issues. Four hundred twenty-nine nuclear power plants are operating world widely producing 16% of the total electric power with total plant capacity of 386 GWe without emission of CO{sub 2} as of 2006. It is estimated that another 250 GWe nuclear power is needed to keep the same level contribution of electricity generation in 2030. On the other hand, the Japan Atomic Energy Research Institute (JAERI) developed the very high temperature gas-cooled reactor (HTGR) named high temperature gas-cooled engineering test reactor (HTTR) and carbon free hydrogen production process (IS process). Nuclear energy utilization will surely widen in, not only electricity generation, but also various industries such as steel making, chemical industries, together with hydrogen production for transportation by introduction of HTGRs. The details of development of the HTTR and IS process are also described.

    The Global Nuclear Futures Model (GNFM) is a dynamic simulation tool that provides an integrated framework to model key aspects of nuclear energy, nuclear materials storage and disposition, global nuclear materials management, and nuclear proliferation risk. It links nuclear energy and other energy shares dynamically to greenhouse gas emissions and twelve other measures of environmental impact. It presents historical data from 1990 to 2000 and extrapolates energy demand through the year 2050. More specifically, it contains separate modules for energy, the nuclear fuel cycle front end, the nuclear fuel cycle back end, defense nuclear materials, environmental impacts, and measures of the potential for nuclear proliferation. It is globally integrated but also breaks out five regions of the world so that environmental impacts and nuclear proliferation concerns can be evaluated on a regional basis. The five regions are the United States of America (USA), The Peoples Republic of China (China), the former Soviet Union (FSU), the OECD nations excluding the USA, and the rest of the world (ROW).

    This presentation is entitled, 'The Future of Nuclear Power Worldwide and the Role of the Global Nuclear Energy Partnership', and the core message in one sentence is: When we look at the challenges of meeting our growing energy demands, providing for energy security and reducing greenhouse gas emissions, we must conclude that nuclear power has to play a significant and growing role in meeting these challenges. Similarly, the mission of the Global Nuclear Energy Partnership is to foster the safe and secure worldwide expansion of nuclear energy. GNEP comes at a crucial time in the burgeoning expansion of nuclear power. It is the only comprehensive proposal to close the nuclear fuel cycle in the United States, and engage the international community to minimize proliferation risks as well as provide and benefit from cooperation in policy formation, technical support, and technology and infrastructure development. Nuclear power's poised renaissance is encouraging, but it will require public support, expanded R and D activities and facilities, and increases in human capital needed for wide-scale construction and operation of new nuclear plants. Despite recent political currents, Germany can, too, become a part of this renaissance and become a full partner in the global partnership that shares a common vision for nuclear power's expansion.

    The EnerFuture service provides projections to 2035 of energy supply and demand across the world, powered by the POLES model, to help you with what to expect in the energy industry in the mid-term. Our energy forecasting team have developed three key energy scenarios (Balance, Emergence and Renaissance) to illustrate possible futures. Balance scenario: Balance provides an outlook of the energy system up to 2035 based on current policies and trends. Sustained growth of China and other emerging countries is a powerful driver of global energy demand, but confirmed energy policy commitments in several regions play a key role in controlling the pace of growth. However, non-coordinated policies result in soaring CO_2 emissions across the world and energy prices rise. Emergence scenario: This scenario explores the implications of more stringent climate policies, with more ambitious efforts on energy efficiency, initiatives to phase out fossil fuel subsidies and a real emergence of renewable technologies. Europe goes beyond its -20% targets by 2020, and the OECD and emerging countries meet their Copenhagen objectives. Following this, a new green deal is launched to reduce world emissions by a factor of 2 by 2050. Renaissance scenario: With strong efforts in the exploitation and production of unconventional oil and gas resources, the world encounters a fossil fuels renaissance with the appearance of new key actors and ultimately new geopolitical configurations changing the energy independence of several countries. For climate efforts, this new paradigm leads to progressively weaker policies. Further analysis and key findings are available here: - Increasing economic activity and wealth drives energy consumption, in a balance between energy prices and innovation; - As Non-OECD exceeds OECD oil demand, massive financial flows underlie the shifts in global oil trade; - Optimistic resource assumptions and moderate production costs would lead to an oil production Renaissance

    A global energy, economics, environment (E{sup 3}) model has been adopted and modified with a simplified, but comprehensive and multi-regional, nuclear energy module. Using this model, consistent nuclear energy scenarios are constructed. A spectrum of future is examined at two levels in a hierarchy of scenario attributes in which drivers are either external or internal to nuclear energy. Impacts of a range of nuclear fuel-cycle scenarios are reflected back to the higher-level scenario attributes. An emphasis is placed on nuclear materials inventories (in magnitude, location, and form) and their contribution to the long-term sustainability of nuclear energy and the future competitiveness of both conventional and advanced nuclear reactors.

  9. Contribution of air conditioning adoption to future energy use under global warming

    As household incomes rise around the world and global temperatures go up, the use of air conditioning is poised to increase dramatically. Air conditioning growth is expected to be particularly strong in middle-income countries, but direct empirical evidence is scarce. In this paper we use high-quality microdata from Mexico to describe the relationship between temperature, income, and air conditioning. We describe both how electricity consumption increases with temperature given current levels of air conditioning, and how climate and income drive air conditioning adoption decisions. We then combine these estimates with predicted end-of-century temperature changes to forecast future energy consumption. Under conservative assumptions about household income, our model predicts near-universal saturation of air conditioning in all warm areas within just a few decades. Temperature increases contribute to this surge in adoption, but income growth by itself explains most of the increase. What this will mean for electricity consumption and carbon dioxide emissions depends on the pace of technological change. Continued advances in energy efficiency or the development of new cooling technologies could reduce the energy consumption impacts. Similarly, growth in low-carbon electricity generation could mitigate the increases in carbon dioxide emissions. However, the paper illustrates the enormous potential impacts in this sector, highlighting the importance of future research on adaptation and underscoring the urgent need for global action on climate change.

    With the aggressive deployment of utility-scale and distributed generation of wind and solar energy systems, an accurate estimate of the uncertainty associated with future resource trends and plant performance is crucial in maintaining financial integrity in the renewable energy markets. With continuing concerns regarding climate change, the move towards energy resiliency, and the cost-competitiveness of renewables, a rapidly expanding fleet of utility-scale wind and solar power facilities and distributed generation of both resources is now being incorporated into the electric distribution grid. Although solar and wind account for about 3% of global power production, renewable energy is now and will continue to be the world's fastest-growing energy source. With deeper penetration of renewables, confidence in future power production output on a spectrum of temporal and spatial scales is crucial to grid stability for long-term planning and achieving national and international targets in the reduction of greenhouse gas emissions. Here, we use output from a diverse subset of Earth System Models (Climate Model Inter-comparison Project-Phase 5 members) to produce projected trends and uncertainties in regional and global seasonal and inter-annual wind and solar power production and respective capacity factors through the end of the 21st century. Our trends and uncertainty analysis focuses on the Representative Concentration Pathways (RCP) 4.5 and RCP 8.5 scenarios. For wind and solar energy production estimates, we extract surface layer wind (extrapolated to hub height), irradiance, cloud fraction, and temperature (air temperature affects density [hence wind power production] and the efficiency of photovoltaic [PV] systems), output from the CMIP5 ensemble mean fields for the period 2020 - 2099 and an historical baseline for POR of 1986 - 2005 (compared with long-term observations and the ERA-Interim Reanalysis). Results include representative statistics such as the

    A sound judgement on the role of nuclear power in the global energy balance within the time span of the next 30 years should logically be based on the consideration of at least a number of factors such as global trends in energy and electricity demand, practically available or estimated sources of supply, major requirements that these energy sources should meet, nuclear power's own potential, a realistic assessment of nuclear power's present status, and problems related to nuclear power. The conclusion of such an analysis is that nuclear power will retain, and may even enhance, its position as an important element in the world's energy supply mix

    Various international dynamics are converging to increase the attractiveness of decentralized energy as a complement to existing centralized energy infrastructures. Decentralized energy (DE) technologies, including onsite renewables, high efficiency cogeneration and industrial energy recycling, offer considerable benefits to those seeking working alternatives to emerging challenges in the energy sector. DE is ideally suited to provide clean affordable energy to areas where modern energy services are currently lacking. Having smaller generators close to where energy is required ensures a safe, reliable and secure energy supply when the energy is required. Furthermore, because DE is a much cleaner alternative than conventional central power plants and the energy provided comes at a much smaller price tag DE is an increasingly acceptable alternative both in the developed and developing world. DE is sure to play a key role in any plan to build a sustainable energy future. (auth)

  20. Future energy, exotic energy

    The Detroit Energy Conference has highlighted the declining oil reserves, estimated worldwide at 95 billion tons vs. an annual rate of consumption of over 3 billion tons. The present problem is one of price; also, petroleum seems too valuable to be simply burned. New sources must come into action before 1985. The most abundant is coal, with 600 billion tons of easily recoverable reserves; then comes oil shale with a potential of 400 billion tons of oil. Exploitation at the rate of 55 go 140 million tons/yr is planned in the U.S. after 1985. More exotic and impossible to estimate quantitatively are such sources as wind, tides, and the thermal energy of the oceans--these are probably far in the future. The same is true of solar and geothermal energy in large amounts. The only other realistic energy source is nuclear energy: the European Economic Community looks forward to covering 60% of its energy needs from nuclear energy in the year 2000. Even today, from 400 mw upward, a nuclear generating plant is more economical than a fossil fueled one. Conservation will become the byword, and profound changes in society are to be expected.

This scenario is expecting supply to be dominated by fossil fuel (80% in 1990 and still 65% in 2050), with high share of natural gas and nuclear with slow growth in renewable energy. 10) A more radical scenario (C1) is expecting renewable energy such as biomass, solar and wind to contribute 27% in 2050; declining oil and coal; increased use of natural gas and a minor contribution from nuclear. A development path like this require significant near-term investments in technology research and development. 11) The large increase in global energy demand in the next century will require large investments

    2008-01-01

    This paper examines the potential roles of Fischer-Tropsch (FT) synfuels in the 21st century with a global energy model treating the entire fuel supply chain in detail. The major conclusions are the following. First, FT synfuels become a major alternative fuel regardless of CO 2 policy due to their low transportation costs and compatibility with existing petroleum infrastructure and vehicles. Secondly, the FT process brings stranded gas to world markets until around 2050. In a 550 ppm CO 2 stabilization case thereafter, producing FT synfuels from biomass, whose competitiveness is robust against its capital costs, and their interregional trade enable a worldwide diffusion of carbon-neutral fuels. This provides a significant source of income for developing regions, such as Latin America and Sub-Saharan Africa. Thirdly, FT synfuels play a crucial role in meeting the growing transportation energy demand and assuring diversified supplies of transportation fuels. Increasing portions of FT liquids are refined to FT-kerosene to be provided for the rapidly growing aviation sector in the second half of the century. Furthermore, upgrading FT-naphtha into FT-gasoline proves to be critically important. FT synfuels' participation could help the development in Africa through technological contributions of the South African leading companies in the world synfuel industry

  4. Coal and Oil: The Dark Monarchs of Global Energy: Understanding Supply and Extraction Patterns and their Importance for Future Production

    Hoeoek, Mikael

    2010-01-01

    The formation of modern society has been dominated by coal and oil, and together these two fossil fuels account for nearly two thirds of all primary energy used by mankind. This makes future production a key question for future social development and this thesis attempts to answer whether it is possible to rely on an assumption of ever increasing production of coal and oil. Both coal and oil are finite resources, created over long time scales by geological processes. It is thus impossible to extract more fossil fuels than geologically available. In other words, there are limits to growth imposed by nature. The concept of depletion and exhaustion of recoverable resources is a fundamental question for the future extraction of coal and oil. Historical experience shows that peaking is a well established phenomenon in production of various natural resources. Coal and oil are no exceptions, and historical data shows that easily exploitable resources are exhausted while more challenging deposits are left for the future. For oil, depletion can also be tied directly to the physical laws governing fluid flows in reservoirs. Understanding and predicting behaviour of individual fields, in particularly giant fields, are essential for understanding future production. Based on comprehensive databases with reserve and production data for hundreds of oilfields, typical patterns were found. Alternatively, depletion can manifest itself indirectly through various mechanisms. This has been studied for coal. Over 60% of the global crude oil production is derived from only around 330 giant oilfields, where many of them are becoming increasingly mature. The annual decline in existing oil production has been determined to be around 6% and it is unrealistic that this will be offset by new field developments, additional discoveries or unconventional oil. This implies that the peak of the oil age is here. For coal a similar picture emerges, where 90% of the global coal production originates

    The track was organized by the Department of Energy Technology, School of Engineering, at Aalto University. Energy future 2050 -track introduced participants to the global long-term challenges of achieving a sustainable energy supply. According to the Intergovernmental Panel on Climate Change (IPCC), effective climate change mitigation would require the global greenhouse gas emissions to be reduced by 50-85% from the present level by 2050. For industrialized countries, this would probably mean a practically carbon-neutral economy and energy supply, as developing countries need more possibilities for growth and probably enter stricter emission reduction commitments with some delay. In the beginning of the workshop, students were introduced to global energy scenarios and the challenge of climate change mitigation. Students worked in three groups with the following topics: How to gain public acceptance of Carbon (dioxide) Capture and Storage (CCS) ? Personal emissions trading as a tool to achieve deep emission cuts, How to get rid of fossil fuel subsidies? Nordic cases are peat use in Finland and Sweden. (orig.)

    Environmental and security concerns are stimulating global interest in hydrogen power, renewable energy, and advanced transportation technologies, but no significant movement away from oil and a carbon-based world economy is expected soon. Over the longer-term, however, a transition from fossil fuels to a non-carbon-based economy will likely occur, affecting the type of environment future generations may encounter. Key challenges will face the world's energy industry over the next few decades to ensure a smooth transition-challenges which will require government and industry solutions beginning as early as today. This paper identifies four critical challenges in energy and the choices which will have to be made on how best to confront growing pollution caused by fossil fuels and how to facilitate an eventual revolutionary-like transition to a non-carbon-based global economy

    India's development aspirations are challenged by energy security and climate change considerations. The integrated energy policy clearly deliberates the need to intensify all energy options with emphasis on maximizing indigenous coal production, harnessing hydropower, increasing adoption of renewables, intensifying hydrocarbon exploration and production and anchoring nuclear power development to meet the long-term requirements. The report also emphasizes the need to secure overseas hydrocarbon and coal assets. Subsequently the National Action Plan on climate change has underscored the need to wean away from fossil fuels, the ambitious National Solar Mission is a case in point. Ultimately securing India's energy future lies in clean coal, safe nuclear and innovative solar. Coal is the key energy option in the foreseeable future. Initiatives are needed to take lead role in clean coal technologies, in-situ coal gasification, tapping coal bed methane, coal to liquids and coal to gas technologies. There is need to intensify oil exploration by laying the road-map to open acreage to unlock the hydrocarbon potential. Pursue alternate routes based on shale, methane from marginal fields. Effectively to use oil diplomacy to secure and diversify sources of supply including trans-national pipelines and engage with friendly countries to augment strategic resources. Technologies to be accessed and developed with international co-operation and financial assistance. Public-Private Partnerships, in collaborative R and D projects need to be accelerated. Nuclear share of electricity generation capacity to be increased 6 to 7% of 63000 MW by 2031-32 and further to 25% (300000 MW) capacity by 2050 is to be realized by operationalizing the country's thorium programme.

    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

The report does not go into a lot of detail on these issues and hence, it is meant as an overview only. The report begins by outlining...... the causes of global climate change, concluding that energy-related emissions are the primary contributors to the problem. As a result, global energy production is analysed in more detail, discussing how it has evolved over the last 30 years and also, how it is expected to evolve in the coming 30 years....... Afterwards, the security of the world’s energy supply is investigated and it becomes clear that there is both an inevitable shortage of fossil fuels and a dangerous separation of supply and demand. The final topic discussed is renewable energy, since it is one sustainable solution to the global energy...

    A discussion of some of the global risks associated with current and frequently proposed future levels of consumption of energy from oil, coal, fission, fusion, and renewable sources points out the the dangers are serious and relatively near term. These include world war over Persian Gulf oil, climate change due to the buildup of atmospheric carbon dioxide, the accelerated proliferation of nuclear weapons, and competition between food and energy for land and water. The author urges placing a greater emphasis on how we use energy and how to reduce energy waste. At the levels of consumption which economically justified levels of energy efficiency could bring about, enough flexibility could develop in our choice of a future energy-supply mix to dramatically reduce the associated global risks. 47 references, 3 figures

    Because of the inevitable depletion of fossil fuels and the corresponding release of carbon to the environment, the global energy future is complex. Some of the consequences may be politically and economically disruptive, and expensive to remedy. For the next several centuries, fuel requirements will increase with population, land use, and ecosystem degradation. Current or projected levels of aggregated energy resource use will not sustain civilization as we know it beyond a few more generations. At the same time, issues of energy security, reliability, sustainability, recoverability, and safety need attention. We supply a top-down, qualitative model--the surety model--to balance expenditures of limited resources to assure success while at the same time avoiding catastrophic failure. Looking at U.S. energy challenges from a surety perspective offers new insights on possible strategies for developing solutions to challenges. The energy surety model with its focus on the attributes of security and sustainability could be extrapolated into a global energy system using a more comprehensive energy surety model than that used here. In fact, the success of the energy surety strategy ultimately requires a more global perspective. We use a 200 year time frame for sustainability because extending farther into the future would almost certainly miss the advent and perfection of new technologies or changing needs of society.

The two interviews concern an interview with BP Alternative Energy ceo Vivienne Cox, and an interview with the founder and CEO of New Energy Finance Michael Liebreich. The column ('An efficient response') focuses on the impact of the economic crisis on energy policy.

  20. Toward sustainable energy futures

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

    The Danish Government's plan ''Our Future Energy'' seeks to create green growth and help the country convert to 100 percent renewable energy use by 2050. The Danish Government in November 2011 presented its plan for how the country can secure its energy future. Titled ''Our Future Energy'', the strategy presents specific measures for fulfilling the Government's goal of stimulating green growth. The plan is based on the previous government's Energy Strategy 2050, but raises the bar higher. The long-term goal of the plan is to implement an energy and transport network that relies solely on renewable energy sources. By 2020, the initiatives will lead to extensive reductions in energy consumption, making it possible for half of the country's electricity consumption to be covered by wind power. Coal is to be phased out of Danish power plants by 2030. And by 2035, all electricity and heating will be generated using renewable sources. (Author)

  2. Fusion: Energy for the future

    1991-05-01

    Fusion, which occurs in the sun and the stars, is a process of transforming matter into energy. If we can harness the fusion process on Earth, it opens the way to assuring that future generations will not want for heat and electric power. The purpose of this booklet is to introduce the concept of fusion energy as a viable, environmentally sustainable energy source for the twenty-first century. The booklet presents the basic principles of fusion, the global research and development effort in fusion, and Canada's programs for fusion research and development

    Starr, C.

    1979-01-01

    After examining briefly the usual positions of nuclear critics and nuclear proponents, Dr. Starr says that the proponents (of whom he is one) have a broader case for nuclear power not thus far effectively advanced - a case based chiefly on a visible concern with social values and the future welfare of humanity. Such a broader case for nuclear power has always existed - a case based on motivations that initially spurred development of this energy resource over the past several decades, but one that has tended to be neglected in the public debate. A concern to avoid worldwide catastrophe is central to this broader case for nuclear power. The threat is perceived as resulting directly from the pending unavailability of petroleum and natural gas at a reasonable cost. This unavailability could lead to global tensions and political instabilities, economic crises, and, ultimately, to military conflicts based on need to obtain and control liquid-fuel resources. It is felt that past history and current events substantiate the threat inherent in the international struggle for raw materials. The broader - and more compelling - case for nuclear power lies in its potential for removing a major threat to the peace, stability, and welfare of the world that is inherent in the growing scarcity of petroleum and natural gas resources and in the limited geographical availability of coal. The catastrophe that could be avoided is at least as threatening as the one projected by those who oppose the use of nuclear power, and, Dr. Starr argues, more realistic in its potential for world-shattering impacts

    The article discusses not only the future of energy and resource consumption in various areas of the world, but also its development over the centuries since the industrial revolution. The present situation, with large discrepancies between the energy consumption of industrialised nations and the developing countries is examined. Social and environmental aspects are discussed and the sustainable use of the Earth's resources and the inconsistencies in this area is looked at. Rather than adopting a moralistic approach, the article appeals to man's powers of innovation and sense of responsibility in order to develop solutions to today's and future energy supply problems. The article is richly illustrated with diagrams and graphs on world energy and social statistics

    At present about 90% of the world's energy consumption is met by the fossil carbon fuel used in the form of coal, oil and natural gas. This results into release of vast amounts of waste gas CO 2 into the atmosphere posing a threat to the global environment. Moreover this energy source is not sustainable (renewable) and its use amounts to spending Earth's capital resources. The options to this energy source are biomass energy, hydro power, solar energy, geothermal energy and nuclear energy. The potentials, limitations, geological impact and environmental dangers, if any, of these sources are discussed in brief. Energy conservation through energy efficient systems is also one more option. Problems and potential for change to sustainable energy systems with respect to India and Canada are examined. Finally it is pointed out that the ultimate solution to the world's energy problem lies in population control and population reduction. This will make possible for the world to have a sustainable energy system primarily based on solar energy. (M.G.B.). 15 refs

    The foreseeable energy future will be driven by economics of known technologies and the desire to reduce CO 2 emissions to the atmosphere. Renewable energy options are compared with each other and with the use of fossil fuels with carbon capture and sequestration (CCS). Economic analysis is used to determine the best of several alternatives. One can disagree on the detailed costs, including externalities such as climate change and air and water pollution. But the differences in capital and operating costs between known technologies are so significant that one can draw clear conclusions. Results show that renewable energy cannot compete with fossil fuels on a cost basis alone because energy is intrinsic to the molecule, except for hydroelectricity. However, fossil fuels are implicated in climate change. Using renewable energy exclusively, including transportation and electricity needs, could reduce the standard of living in the United States by 43% to 62%, which would correspond to the level in about 1970. If capture and sequester of CO 2 are implemented, the cost of using fossil fuels will increase, but they beat renewable energy handily as an economic way to produce clean energy.

    Global warming caused by increase in atmospheric CO 2 concentration has been the focus of many recent global energy studies. CO 2 is emitted to the atmosphere mainly from the combustion of fossil fuels. This means that global warming is fundamentally a problem of the global energy system. An analysis of the findings of recent global energy studies is made in this report. The results are categorized from the viewpoint of concern about global warming. The analysis includes energy use and CO 2 emissions, measures taken to restrain CO 2 emissions and the cost of such measure, and suggestions for long term global energy generation. Following this comparative analysis, each of the studies is reviewed in detail. (author) 63 refs

    2009-01-01

    In the last 2000 years the world's population and the worldwide total energy consumption have been continuously increasing, at a rate even greater than exponential. By now a situation has been reached in which energy resources are running short, which for a long time have been treated as though they were almost inexhaustible. The ongoing growth of the world's population and a growing hunger for energy in underdeveloped and emerging countries imply that the yearly overall energy consumption will continue to grow, by about 1.6 percent every year so that it would have doubled by 2050. This massive energy consumption has led to and is progressively leading to severe changes in our environment and is threatening a climatic state that, for the last 10 000 years, has been unusually benign. The coincidence of the shortage of conventional energy resources with the hazards of an impending climate change is a dangerous threat to the well-being of all, but it is also a challenging opportunity for improvements in our energy usage. On a global scale, conventional methods such as the burning of coal, gas and oil or the use of nuclear fission will still dominate for some time. In their case, the challenge consists in making them more efficient and environmentally benign, and using them only where and when it is unavoidable. Alternative energies must be expanded and economically improved. Among these, promising techniques such as solar thermal and geothermal energy production should be promoted from a shadow existence and further advanced. New technologies, for instance nuclear fusion or transmutation of radioactive nuclear waste, are also quite promising. Finally, a careful analysis of the national and global energy flow systems and intelligent energy management, with emphasis on efficiency, overall effectiveness and sustainability, will acquire increasing importance. Thereby, economic viability, political and legal issues as well as moral aspects such as fairness to disadvantaged

    The interest of politicians, businessmen, technologists, scientists and the people at large is focused today on the problem of energy. Everybody will agree on the fact that energy is necessary for the future of mankind. But many tend to paraphrase this by saying that energy is necessary evil. No objection to the necessity: but an analysis of the motivations for regarding energy as evil reveals some Freudian undertones. This scepticism towards technology, as a solution to the rising environmental concerns, perceived as a Faustian deal, after centuries of a passionate technical endeavour deeply engraved in the conception of the world, is a curious phenomenon to say the least. All these problems and the associated concerns are serious: the inevitable growth of energy consumption under the sheer momentum of society and the very human expectations of the poor, may indeed add enough yeast to make them leaven beyond control. However, like in the case of famine, illness etc., also here science and technology should be trusted; indeed there are reasonable expectations that, combined, they will have the possibility of solving also this problem, in full accord with the economic, dynamic and technical constraints that a working system has to comply with

    Australia has one of the most cost-effective energy conversion and delivery systems in the world. We are blessed with abundant, high-quality fossil fuels consisting mainly of coal, gas and (diminishing) oil resources. However, this past blessing is also a future curse as this fuel mix, coupled with limits to hydroelectric growth and no nuclear generation capacity, has endowed Australia with one of the highest greenhouse gas (GHG) emissions per unit of GDP in the developed world (currently 43 per cent above the International Energy Agency average). This prompted Claude Mandil, head of the IEA, to observe: 'Environmental sustainability represent Australia's greatest energy challenge, with high and growing carbon dioxide emissions.' The challenge for Australia is how to make the massive cuts in GHG emissions required to minimise our world trade risks (which will come at a cost, and put pressure on our energy cost-effectiveness) while maintaining an internationally competitive energy sector. This challenge is exacerbated by a healthy national growth rate which will be accompanied by at least a 50 per cent growth in energy demand by 2020, with a doubling by 2050. Electricity industry projections predict an investment in new generation capacity well in excess of $30 billion to keep up with demand over the next two decades. The stark reality is that if we con tinue to supply and use energy the way we do now, we may as well forget about stabilising our GHG emissions from the energy sector, let alone reducing them in the future. This urgent situation presents a huge opportunity for the introduction of new and improved low-emission energy conversion technologies and demand management systems that vastly reduce GHG emissions per unit of productivity - in fact, an opportunity to transform Australia's energy sector to levels of innovation, social acceptance and environmental performance that has no precedent in this country. We have little choice other than to make a start. Are

    Birjandi, Hossein Saremi

    Before the Industrial Revolution, nations required no energy fuel. People relied on human, animal, and wind and waterpower for energy need. Energy (oil) has resettled populations, elected officials in the free world, or changed the governments of the energy rich countries by force. Energy fueled wars, played the major factor in the might of those who have it or more importantly the abilities to acquire it by force. This dissertation researches the primacy of oil as an energy source from the time of oil's discovery to the present times. Between 1945 and 1960, the use of oil and gas doubled as power was generated for industries as steel, cement, metalworking and more important of all filling station hoses into automobiles gas tanks, thus energy swept people and societies quite literally off their feet. One in every six jobs in the industrial world hired by the giant automotive industries. The big five American oil companies spurred on by special tax benefit, these companies grew to gigantic sizes by taking out the best part of the nation's oil. Then, for greater growth, they leaped overseas and built up an immensely profitable system, in alliance with Anglo-Dutch Shell and British Petroleum, known as seven sisters. On the other side of the world, the energy producing nations form an alliance mainly to protect themselves from downward price fluctuations of oil. The struggle for survival in the global energy market forced those countries to get together and form OPEC, which is referred as an "oil cartel".

    In spite of the easing of worldwide energy supply and demand situation in these years, we believe that research efforts towards the next generation nuclear energy are indispensably necessary. Firstly, the nuclear colleagues believe that nuclear energy is the best major energy source from many points of view including the global environmental viewpoint. Secondly, in the medium- and long-range view, there will once again be a high possibility of a tight supply and demand situation for oil. Thirdly, nuclear energy is the key energy source to overcome the vulnerability of the energy supply structure in industrialized countries like Japan where virtually no fossil energy source exists. In this situation, nuclear energy is a sort of quasi-domestic energy as a technology-intensive energy. Fourthly, the intensive efforts to develop the nuclear technology in the next generation will give rise to a further evolution in science and technology in the future. A few examples of medium- and long-range goals of the nuclear energy research are development of new types of reactors which can meet various needs of energy more flexibly and reliably than the existing reactors, fundamental and ultimate solution of the radioactive waste problems, creation and development of new types of energy production systems which are to come beyond the fusion, new development in the biological risk assessment of the radiation effects and so on. In order to accomplish those goals it is quite important to introduce innovations in such underlying technologies as materials control in more microscopic manners, photon and particle beam techniques, accelerator engineering, artificial intelligence, and so on. 32 refs, 2 figs

    The National Energy Board hosted this Energy Futures Workshop as a follow-up to its report entitled Canada's Energy Future: Reference Case and Scenarios to 2030, which focused on emerging trends in energy supply and demand. Various energy futures that may be available to Canadians up to the year 2030 were examined. This workshop addressed issues regarding the growing demand for energy, the adequacy of future energy supplies, and related issues of greenhouse gas emissions, emerging technologies, energy infrastructure and energy exports. The workshop was attended by 18 experts who presented their diverse views on long-term energy issues. The sessions of the workshop focused on external and key geopolitical issues that will influence Canadian energy markets; the adoption of alternative and emerging sources of energy; outlook for Canadian oil supply, including oil sands development, reservoir quality, and financial, environmental and technological issues; issues in electricity generation and transmission; gas market dynamics; and carbon dioxide capture and storage and the associated benefits and challenges. There was general consensus that global and Canadian energy markets will remain in a state of flux. Crude oil prices are likely to remain high and volatile. The combination of maturing energy resource basins and geopolitical tensions has created uncertainty about future availability and access to global energy resources. 2 figs., 3 appendices

    The new Asia-Pacific Greenhouse Agreement offers Australia a great opportunity to take full advantage of both its brains and its energy resources. The energy debate is often, simplistically, characterised as coal versus nuclear, or non-renewables versus renewables. In reality we will need a mix of energy sources to power our economy, cleanly, into the future. The issues are cost, environmental protection, national security, skills and security of energy supply. If we wish our economy to continue growing at present rates, we will need 50 per cent more energy in 2030 than we use today - and it is not too soon to start planning how we will produce it. We have around 500 years' supply of coal resources at present rates of usage. Power generation from coal is capable of achieving zero, or near zero, carbon emissions using technologies such as oxy-fuel combustion or IGCC (integrated gasification combined cycle). In both, C0 2 can be captured and stored underground. The greenhouse debate has revived interest in nuclear power generation. The cost of generating electricity with nuclear is similar to clean coal. However, we would have to start a nuclear power industry from a very small base, buying costly generation plant and training or importing an entire, highly-skilled workforce, in competition with other countries. Waste disposal is an issue for both coal and nuclear. For coal, the main option is carbon capture and its storage in deep saline aquifers. This technology is well understood and widely used by the oil and gas industry but we have to determine the most suitable places and techniques, and we have to build the infrastructure. Nuclear waste storage is also well-understood. Which technology we choose depends on an evaluation of both short and long term risks for the community and environment. One thing that Australia must get right is the economics. The wrong decision will cost us jobs, if not entire industries and regions. While renewables like solar and wind are

    1999-01-01

    Perhaps the most compelling issue the world will face in the next century is the quality of life of the increasing populations of the poorer regions of the world. Energy is the key to generating wealth and protecting the environment. Today, most of the energy generated comes from fossil fuels and there should be enough for an increase in consumption over the next half century. However, this is likely to be impacted by the Kyoto Protocol on carbon dioxide emissions. Various authoritative studies lead to a global energy demand projection of between 850 to 1070 EJ per year in the mid-21 st century, which is nearly three times as much as the world uses today. The studies further indicate that, unless there is a major thrust by governments to create incentives and/or to levy heavy taxes, the use of fossil fuels will continue to increase and there will be a major increase in carbon dioxide emissions globally. Most of the increase will come from the newly industrializing countries which do not have the technology or financial resources to install non-carbon energy sources such as nuclear power, and the new renewable energy technologies. The real issue for the nuclear industry is investment cost. Developing countries, in particular will have difficulty in raising capital for energy projects with a high installed cost and will have difficulties in raising large blocks of capital. A reduction in investment costs of the order of 50% with a short construction schedule is in order if nuclear power is to compete and contribute significantly to energy supply and the reduction of carbon dioxide emissions. Current nuclear power plants and methods are simply not suited to the production of plants that will compete in this situation. Mass production designs are needed to get the benefits of cost reduction. Water cooled reactors are well demonstrated and positioned to achieve the cost reduction necessary but only via some radical thinking on the part of the designers. The reactors of

    When I say 'globalization', I think to that golden beginning when President Eisenhower gave his historical speech, 'Atomic Power for Peace,' to the General Assembly of U.N.O. in 1953. He proposed, for the first time, an international cooperation for sustaining the peaceful application of nuclear energy. Years later, the global nuclear dream was shaken by Chernobyl. Humankind had seen the reverse of globalization: any lack in project, execution, or operation of an NPP has global consequences. Still, why globalization? Globalization because global urbanization trends are an important factor for energy planners and this debate is vital for fueling the bigger cities of tomorrow. (author)

    Appendix A contains the Monte Carlo Data Set. The data sheets give the distribution for input variables used in Monte Carlo analysis of the IEA/ORAU Global Energy, CO{sub 2} Model. The data sheets include a discussion of data sources, bibliographic sources, and other considerations used in developing the particular data format and values for distributions. As much detail as possible about how distributions are related to published estimates is given but in most cases it was necessary to make a significant leap from available data to the quantified distribution. The distributions are meant to be roughly accurate and to the degree that uncertainty exists about the form and value of distributions, the authors have tended to opt for wider bounds. Appendix B contains The IEA/ORAU Long-Term Global Energy-CO{sub 2} Model, Version A.84 -- Model Improvements. The model was originally developed in 1982 in support of work conducted for the US Department of Energy Carbon Dioxide Research Division in the area of future global fossil fuel related CO emissions research. The uncertainty analysis, documented in this report, made demands on the model that had not previously been made, and in the process of operating the model much was learned about areas in which simplification or elaboration was justified, or in which a different approach was warranted. As a consequence of these criticisms, demands, and learning numerous model modifications were undertaken. Since two versions of the model now exist, version specifications have been adopted. The 1984 version is designated A.84, while the version completed in 1982 is designated B.82. Model changes fall into three categories: those which affect the theoretical structure of the model, those which affect the computational processes of the model, and those which affect only the model by which model inputs are entered.

    This paper contrasts the standard economic approach to energy modelling with energy models using a biophysical approach. Neither of these approaches includes changing energy-returns-on-investment (EROI) due to declining resource quality or the capital intensive nature of renewable energy sources. Both of these factors will become increasingly important in the future. An extension to the biophysical approach is outlined which encompasses a dynamic EROI function that explicitly incorporates technological learning. The model is used to explore several scenarios of long-term future energy supply especially concerning the global transition to renewable energy sources in the quest for a sustainable energy system.

    Full Text Available The objective of this review is to discuss the available data on the prevalence and causes of global blindness, and some of the associated trends and limitations seen. A literature search was conducted using the terms "global AND blindness" and "global AND vision AND impairment", resulting in seven appropriate articles for this review. Since 1990 the estimate of global prevalence of blindness has gradually decreased when considering the best corrected visual acuity definition: 0.71% in 1990, 0.59% in 2002, and 0.55% in 2010, corresponding to a 0.73% reduction per year over the 2002-2010 period. Significant limitations were found in the comparability between the global estimates in prevalence or causes of blindness or visual impairment. These limitations arise from various factors such as uncertainties about the true cause of the impairment, the use of different definitions and methods, and the absence of data from a number of geographical areas, leading to various extrapolation methods, which in turn seriously limit comparability. Seminal to this discussion on limitations in the comparability of studies and data, is that blindness has historically been defined using best corrected visual acuity.

    The very existence of modern civilization is dependent on the supply of energy which comes from sun, geothermal energy sources, hydroelectricity, tides, ocean winds and nuclear sources. Potential of these sources for long-term solution of man's energy problems is examined. Nuclear source of energy is discussed in detail and other sources are dealt in brief. Fission reactor system which is now generating power on commercial basis is described. The work being done on thermonuclear fusion reactor system to make it a practical system is surveyed. Research programs on laser and particle beam fusion are described. (M.G.B.)

    Lameiras, Fernando Soares

    1996-01-01

    Humanity will not face shortage of energy, but may face problems with its use, because every energy source has restrictions. Fossil fuels change the climate,nuclear energy increases the radioactivity and can be used to manufacture weapons, solar energy is very scattered, and geothermal energy is yet not well known. Delicate political issues emerge in this scenario. Due to the magnitude of energy used by many countries, isolated energy policies can disturb all planet. This may delay decisions and result in the lack of energy supply, hindering the development of many regions, or in conflict between countries. In this paper, some analyses and considerations are presented about the future of energy use, including some axiologic features. The role of nuclear energy is analysed, because, maybe, for the first time a energy source was target of axiologic issues that have affected the growth of its demand. These issues are yet to be internalized by other energy sources in the future. (author)

    Pooley, D.

    2005-01-01

    All political parties in the UK accept that we should move away from our reliance on fossil fuels towards a much greater use of alternative energy technologies. Nuclear power is one of these but finds minimal support in the political spectrum. The article reviews the European Commission's Advisory Group on Energy submission to the EC's report entitled 'Key Tasks for European Energy R and D'. The 'strength and weaknesses' of the various 'alternative energy' systems (including nuclear power) are summarised and then the key R and D tasks which, if they are carried out successfully, should make the eight selected technologies significantly more attractive. However, the message here is clear enough: there are no easy options, only a range of very imperfect possibilities, despite what enthusiastic proponents of each may say. Nuclear fission is certainly one of the most attractive options available, but the industry needs to continue to strive to eliminate the possibility of significant off-site releases, whether caused by plant failure or by human error or intention, and to prove beyond reasonable doubt the safety of high-level radioactive waste disposal.

    The influence of China's growing energy demand on world oil markets is considered. Starting from a very low base of energy consumption per capita, China's potential for growth in oil demand is likely still to be subject to the extremely strong impact of a stop-go economic policy in which the availability of oil is used as a macroeconomic control variable to counter inflation. This has led to considerable monthly variations in oil import levels. While this situation continues, the buying pressure from China will tend to alternate between a trickle and a flood with consequent destabilizing impacts on the market. The markets potentially involved are those of Asia, the Middle East, West Africa and the Mediterranean with knock-on effects in the North Sea and Rotterdam. China is likely to constitute a major indirect force in these markets as a volatile source of demand at the margin. (UK)

    of CO_2 emissions is good news compared to previous years. This is mainly due to the relative weakness of economic growth. Achieving the goals discussed at the COP21 (1.5 to 2 deg. temperature increase by the end of the century), in fact requires a lasting stagnation of global energy consumption and a strong reduction of CO_2 emissions. Thus, with a global GDP growth assumption of 3% per year, this would imply an average carbon intensity reduction target of 5 to 6% per year... (Source: EnerFuture Scenarios - Enerdata) If energy consumption is stagnating, however, we find different trends according to the markets: The oil market is particularly linked to the transport sector; the increase in demand recorded in 2015 (+2%) derives primarily from the increase in vehicle fleet (China, India...) and to a lesser extent from lower prices (particularly in the US). The decline in investments in the upstream sector leaves us to predict, however, a decrease in mid-term production capacity and new pressure on supply/demand.. Gas demand remained stable in 2015: The structural increase continues in the US (replacing coal); in a more cyclical manner, the demand benefited from a colder climate in Europe but fell sharply in Russia (economic recession). At the production level, the US is No. 1 worldwide before Russia, but with a downward trend for several months (shale gas). Coal consumption decreases: Confirming the surprise in 2014: thanks to a new decline observed in China (-3.7%) and in the US (-11%), and despite continued strong growth in India, demand for coal shrinks at the G20 level (-2.7%). Stagnation of power consumption: The demand in power has been stagnant for several years in developed countries. The result is more surprising for non-OECD countries, where growth shrinks significantly. Is this a sign of a slowdown of the increasing weight of power in the overall mix? Power mix continues its slow transformation: In recent years, energy policies have shown visible effects

    Energy markets were not immune to the 2007 financial crisis. Growth in the Indian and Chinese economies is placing strains on global energy supplies that could force a repeat of the 2008 price spike of $145/bbl for crude oil. Emerging market growth coupled with inefficiencies, frictions, and speculation in the energy markets has the potential to create drastic economic shocks throughout the world. The 2007 economic crisis has pushed back investment in energy projects where a low-growth scenario in world GDP could create drastic price increases in world energy prices. Without a long-term energy supply plan, the U.S. is destined to see growth reduced and its trade imbalances continue to deteriorate with increasing energy costs. Analysis of the U.S. natural gas futures markets and the impact of financial speculation on natural gas market pricing determined that financial speculation adds to price movements in the energy markets, which could cause violent swings in energy prices.

    Current nuclear energy represents 23.5% of the total electrical power available within the OECD countries. This is the energy offering the lowest costs to generate, it does not emit greenhouse-effect fumes nor does it contribute to global warming, however, it does generate radioactive and toxic waste which society perceives as an unacceptable risk. For this reason the development of new nuclear installation in Europe is at a stand still or moving backward. Truthful information and social participation in decisions is the best way to achieve the eradication of the social phobia produced by this energy source. (Author)

    Fossil fuels face resource depletion, supply security, and climate change problems; renewable energy (RE) may offer the best prospects for their long-term replacement. However, RE sources differ in many important ways from fossil fuels, particularly in that they are energy flows rather than stocks. The most important RE sources, wind and solar energy, are also intermittent, necessitating major energy storage as these sources increase their share of total energy supply. We show that estimates for the technical potential of RE vary by two orders of magnitude, and argue that values at the lower end of the range must be seriously considered, both because their energy return on energy invested falls, and environmental costs rise, with cumulative output. Finally, most future RE output will be electric, necessitating radical reconfiguration of existing grids to function with intermittent RE. - Highlights: •Published estimates for renewable energy (RE) technical potential vary 100-fold. •Intermittent wind and solar energy dominate total RE potential. •We argue it is unlikely that RE can meet existing global energy use. •The need to maintain ecosystem services will reduce global RE potential. •The need for storage of intermittent RE will further reduce net RE potential.

    The World Energy Council has designed 2 tools named Jazz and Symphonie that allow the assessment of the potential impacts of energy choices on the future in terms of climate warming, investments, energy mix,... The Jazz roadmap aims at energy equity which means individual access to energy at a reasonable cost while the Symphonie roadmap focuses on environmental issues through appropriate practice and coordinated international policies. Both tools are integrated it means that they describe a whole world by most of its aspects: population, GDP per capita, number of cars by inhabitant, economic growth... A basic application of both tools shows that in 2050 the nuclear power will have increased (compared to today's level) but the share of nuclear power in the energy mix will have decreased for Jazz and increased for Symphonie.

    The global energy sector is going through major changes: the need for energy is growing explosively, while at the same time climate change is forcing US to find new, and cleaner, ways to generate energy. Finland is one of the forerunners in energy technology development, partly because of its northern location and partly thanks to efficient innovations. A network of centres of expertise was established in Finland in 1994 to boost the competitiveness and internationalisation of Finnish industry and, consequently, that of the EU region. During the expertise centre programme period 2007-2013, substantial resources will be allocated to efficient utilisation of top level expertise in thirteen selected clusters of expertise.

  19. Global wind energy outlook 2006

    International Nuclear Information System (INIS)

    2006-09-01

    The global market for wind power has been expanding faster than any other source of renewable energy. From just 4,800 MW in 1995 the world total has multiplied more than twelve-fold to reach over 59,000 MW at the end of 2005. The international market is expected to have an annual turnover in 2006 of more than euro 13 billion, with an estimated 150,000 people employed around the world. The success of the industry has attracted investors from the mainstream finance and traditional energy sectors. In a number of countries the proportion of electricity generated by wind power is now challenging conventional fuels. The Global Wind Energy Outlook 2006 reports that over a third of the world's electricity - crucially including that required by industry - can realistically be supplied by wind energy by the middle of the century. The report provides an industry blueprint that explains how wind power could supply 34% of the world's electricity by 2050. Most importantly, it concludes that if wind turbine capacity implemented on this scale it would save 113 billion tonnes of CO2 from entering the atmosphere by 2050. This places wind power as one of the world's most important energy sources for the 21st century. The 'Global Wind Energy Outlook 2006' runs three different scenarios for wind power - a Reference scenario based on figures from the International Energy Agency (IEA); a Moderate version which assumes that current targets for renewable energy are successful; and an advanced version assuming that all policy options in favour of renewables have been adopted. These are then set against two scenarios for global energy demand. Under the Reference scenario, growth in demand is again based on IEA projections; under the High Energy Efficiency version, a range of energy efficiency measures result in a substantial reduction in demand

    such changes entailed reduced or increased environmental impacts? Are there any identifiable patterns that could serve for steering future energy planning? To address these questions, we applied life cycle assessment to quantify a whole spectrum of environmental impacts caused by electricity generation in 199...... countries for the period 1980– 2011, with national differentiation of energy sources and, wherever possible, technology efficiencies. The results show that (i) environmental impact burden-shifting has occurred in the past for several countries as a result of national policies, (ii) all environmental impacts...... environmental impacts associated with foreseen energy systems when identifying the most sustainable energy pathways. We provide recommendations on the use of life cycle assessment for such purposes with a strong focus on application at the country level so that it can directly support national energy policy-making....

  1. Future of high energy physics

    Panofsky, W.K.H.

    1984-06-01

    A rough overview is given of the expectations for the extension of high energy colliders and accelerators into the xtremely high energy range. It appears likely that the SSC or something like it will be the last gasp of the conventional method of producing high energy proton-proton collisions using synchrotron rings with superconducting magnets. It is likely that LEP will be the highest energy e+e - colliding beam storage ring built. The future beyond that depends on the successful demonstrations of new technologies. The linear collider offers hope in this respect for some extension in energy for electrons, and maybe even for protons, but is too early to judge whether, by how much, or when such an extension will indeed take place

    The rise in global energy consumption is driven by economic growth, particularly in developing countries. It is expected that by 2030, the world population will consume 50 per cent more energy than today. This increase in global energy demand can no longer be met through the business as usual approach. Graphs depicting emerging energy demand in Asia were presented for nuclear energy, coal, natural gas, oil and renewables. The issue of how China can meet it's growing energy demand was discussed with reference to energy consumed by its industrial, agricultural, commercial, residential and transportation sectors. The author emphasized the uneven distribution of resources, where consuming areas do not coincide with producing areas. It is expected that traditional energy sources will still supply most of the world's energy need for the foreseeable future, but they will leave less of an environmental impact. The author suggested that renewable energy sources will also increase but will comprise less than 20 per cent of the world supply in 2050. The author also discussed the issue of greenhouse gas (GHG) emissions, Kyoto obligations and projections of what will happen with Kyoto post 2012. Canada's GHG record and recent environmental findings were also discussed with reference to Arctic ice coverage and the decline in average winter temperature. It was suggested that technology is the key to the energy shortage the environment and security. With declining conventional oil reserves, old nuclear technology and aging electric power technology, new technology must be used to address supply issues, distribution, interconversion, environmental impacts and risks. It was emphasized that since the energy sector is Canada's greatest economic driver, Canada should focus on energy technologies to build a more competitive energy sector. Huge export opportunities also exist for energy technologies. The role of industry and governments in achieving this goal was also discussed. figs

    Full Text Available The future energy system will change significantly within the next years as a result of the following Mega Trends: de-carbonization, urbanization, fast technology development, individualization, glocalization (globalization and localization and changing demographics. Increasing fluctuating renewable production will change the role of non-renewable generation.

    The future energy system will change significantly within the next years as a result of the following Mega Trends: de-carbonization, urbanization, fast technology development, individualization, glocalization (globalization and localization) and changing demographics. Increasing fluctuating renewable production will change the role of non-renewable generation. Distributed energy from renewables and micro generation will change the direction of the energy flow in the electricity grids. Production will not follow demand but demand has to follow production. This future system is enabled by the fast technical development of information and communication technologies which will be present in the entire system.

    Wildfires are an important component of terrestrial ecosystem ecology but also a major natural hazard to societies, and their frequency and spatial distribution must be better understood. At a given location, risk from wildfire is associated with the annual fraction of burned area, which is expected to increase in response to climate warming. Until recently, however, only a few global studies of future fire have considered the effects of other important global environmental change factors such as atmospheric CO2 levels and human activities, and how these influence fires in different regions. Here, we contrast the impact of climate change and increasing atmospheric CO2 content on burned area with that of demographic dynamics, using ensembles of climate simulations combined with historical and projected population changes under different socio-economic development pathways for 1901-2100. Historically, humans notably suppressed wildfires. For future scenarios, global burned area will continue to decline under a moderate emissions scenario, except for low population growth and fast urbanization, but start to increase again from around mid-century under high greenhouse gas emissions. Contrary to common perception, we find that human exposure to wildfires increases in the future mainly owing to projected population growth in areas with frequent wildfires, rather than by a general increase in burned area.

    Nuclear energy for electricity generation will extend its market portion in Europe in the coming decades because: 1) its economic and/or environment-relevant advantages compared with the fossil energy sources are so explicit that the latter will no longer be competitive; 2) the improvements of the system engineering, which are presently being implemented and are to be expected in the future, will enhance the safety facilities to the extent that accident risk will cease to be a decisive factor; 3) energy-saving effects or the use of solar energy will not provide an appropriate large scale alternative for coal and/or nuclear energy; 4) the problems of radioactive waste disposal will be definitely solved within the foreseeable future. Considering all the technological systems available the light water reactor will continue to dominate. The change to the breeder reactor is not yet under discussion because of the medium-term guaranteed uranium supply. The use of nuclear technology in the heating market will depend for the moment on the availability and cost of oil and gas development. In principle nuclear energy can play an important role also in this sector

    Understanding global future river flood risk is a prerequisite for the quantification of climate change impacts and planning effective adaptation strategies. Existing global flood risk projections fail to integrate the combined dynamics of expected socio-economic development and climate change. We present the first global future river flood risk projections that separate the impacts of climate change and socio-economic development. The projections are based on an ensemble of climate model outputs, socio-economic scenarios, and a state-of-the-art hydrologic river flood model combined with socio-economic impact models. Globally, absolute damage may increase by up to a factor of 20 by the end of the century without action. Countries in Southeast Asia face a severe increase in flood risk. Although climate change contributes significantly to the increase in risk in Southeast Asia, we show that it is dwarfed by the effect of socio-economic growth, even after normalization for gross domestic product (GDP) growth. African countries face a strong increase in risk mainly due to socio-economic change. However, when normalized to GDP, climate change becomes by far the strongest driver. Both high- and low-income countries may benefit greatly from investing in adaptation measures, for which our analysis provides a basis.

    2006-01-01

    With climate change gradually emerging as a major global environmental concern, illustrated by the establishment of the UN Framework Convention on Climate Change (UNFCCC) and later the negotiation of the Kyoto Protocol (KP)the role of the energy sector as the main emitter of greenhouse gases has brought a new political rationale for the development of more climate-friendly energy supply and increased efficiency. The last couple of years have seen the increasing importance in the global energy market of rapidly-expanding national economies, notably China and India. Together with other geopolitical developments such as political changes in some of the major oil producing regions, this has produced strong political concerns about future security of supply. This has been compounded by simultaneous dramatic increases in oil and gas prices. The role of energy supply as a key facilitator for economic development in the poorer regions of the world has been increasingly recognised over the last decade. Developing countries are devoting more attention to securing their future energy supplies for a variety of uses: industry, and urban uses and for the poorer communities in both rural and peri-urban areas communities. Global energy policy is therefore dominated by three overriding concerns making them drivers for future energy development activities: 1) security of supply; 2) climate change; 3) energy for development and poverty alleviation. The three areas are in several ways interlinked, and every energy policy or programme should ideally promote them allor at least not have negative effects in any area. In practice, however, many national policy landscapes have been dominated by just one of these factors. (au)

    Toward the future, the petroleum could stop to be the main energy source in the world and the oil companies will only survive if they are adjusted to the new winds that blow in the general energy sector. It will no longer be enough to be the owner of the resource (petroleum or gas) so that a company subsists and be profitable in the long term. The future, it will depend in great measure of the vision with which the oil companies face the globalization concept that begins to experience the world in the energy sector. Concepts like globalization, competition, integration and diversification is something that the companies of the hydrocarbons sector will have very present. Globalization means that it should be been attentive to what happens in the world, beyond of the limits of its territory, or to be caught by competitive surprises that can originate in very distant places. The search of cleaner and friendlier energy sources with the means it is not the only threat that it should fear the petroleum. Their substitution for electricity in the big projects of massive transport, the technology of the communications, the optic fiber and the same relationships with the aboriginal communities are aspects that also compete with the future of the petroleum.

    The book gives a comprehensive analysis of the history and use of different forms of energy, their environmental and social impacts and, in particular, their economic costs and the future of their supply. It examines all the major forms of energy - conventional fuels such as oil and coal, nuclear power and alternative and renewable sources - and includes case studies on the transport and building sectors in the North and agroforestry and fuelwood problems in the South. The authors discuss the development of energy provision and patterns of supply and demand, and examine the use of end-use analyses. They look at the ways in which social and environmental costs should be introduced into energy planning and accounting, and emphasise the crucial role of efficiency to limit over-consumption. 91 refs., 100 figs., 62 tabs.

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

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

    The paper considers the world energy demand till the middle of the century, as well as possible forecasting solution for this challenge. On the base of the mathematical model developed in the Kurchatov Institute in 2003- 2006, the vision of the global nuclear energy system and its potential contribution in the energy mix was analyzed. The rate of rapprochement between specific energy consumptions in different countries of the world is a key parameter determining the energy market strain. It was shown that a continuation of the current world trends of this rapprochement would result in an energy resource deficit already in the nearest future. The energy mix picture would contain an 'unsatisfied demand' area of about 10 000 Mtoe of total energy to be consumed by the mid-century Supposing that the mankind has to meet the 'unsatisfied demand' by nuclear energy, the global energy challenges of the 21. century energy do not impose any upper limit on nuclear energy development, the scale of which would be determined by development opportunities. Russia, as one of the pioneers of the First Nuclear Era, possesses great experience of solving the key issues of nuclear energy of the 20. century, and is capable to play an important role in dealing with the challenges faced by nuclear in the 21. century.

    A variational principle is proposed for constructing equilibria with minimum energy in a toroidal plasma. The total energy is minimized subject to global invariants which act as constraints during relaxation of the plasma. These global integrals of motion are preserved exactly for all idea motions and approximately for a wide class of resistive motions. We assume, specifically, that relaxation of the plasma is dominated by a tearing mode of single helicity. Equilibria with realistic current density and pressure profiles may be constructed in this theory, which is also used here to study current penetration in tokamaks. The second variation of the free energy functional is computed. It is shown that if the second variation of any equilibrium constructed in this theory is positive, the equilibrium satisfies the necessary and sufficient conditions for ideal stability

    In the last quarter of this century, global environmental problem has emerged as a major scientific, political and social issue. Specific Problems include: depletion of ozone layer by chlorofluorocarbons (CFCs), acid rain, destruction of tropical forests and desertification, pollution of the sea and global wanning due to the greenhouse effect by carbon dioxide and others. Among these problems, particular attention of the world has been focused on the global warming because it has direct linkage to energy consumption which our economic development depends on so far. On the other hand, the future program of The Sunshine Project for alternative energy technology R&D, The Moonlight Project for energy conservation technology R&D, and The Global Environmental Technology Program for environmental problem mitigating technology R&D which are Japan`s national projects being promoted by their Agency of Industrial Science and Technology (AIST) in the Ministry of International Trade and Industry have been reexamined in view of recent changes in the situations surrounding new energy technology. In this regard, The New Sunshine Program will be established by integrating these three activities to accelerate R&D in the field of energy and environmental technologies. In the reexamination, additional stress has been laid on the contribution to solving global environmental problem through development of clean renewable energies which constitute a major part of the {open_quotes}New Earth 21{close_quotes}, a comprehensive, long-term and international cooperative program proposed by MITI. The present paper discusses the results of feasibility study on hydrogen energy system leading to the concept of WE-NET following a brief summary on R&D status on solar and wind energy in Japan.

    Nuclear energy appears to be a main asset to France in the context of the worldwide economic slump. Nuclear power provides a cheap electricity that spares the buying power of households and increases the competitiveness of French enterprises. Nuclear industry with major companies like EDF, AREVA and CEA and 450 small and medium-sized enterprises, represents a core resistant to industrial decline. Nuclear industry is a good provider of work and globally it represents 2% of all the jobs in France. Concerning the trade balance, nuclear power plays twice; first by exporting equipment and services for a value of 7 billions euros a year and secondly by sparing the cost of energy imports that would be necessary if nuclear power was not here which is estimated to 20 billions euros a year.

    Global energy demand is growing rapidly at an average rate of 4% per year in parallel with the economy while EU-25 has only 0,8% during the last decade. Total primary energy supply is 87 818 000 toe of which 72% was imported; in comparison the average dependency rate is 49,5% in the EU. Such excessive dependency creates harmful effects on the national economy. Oil and natural gas imports bill was 19,5 billion US $ in 2005. Primary energy demand growth rate is twice as much of the production rate in the period 1980 2004. Fossil fuels accounts for 86% of Turkeys global energy supply in 2004. Population growth rate is one of the major parameters affecting the energy balance. Energy and electricity consumptions per capita are still one third of the EUs average.. Turkeys coal reserves needs to be utilized at higher rate and hydropower, wind power and geothermal energy potentials should be developed in order to decrease the imported energy dependence, soon. Due to the buy or pay bilateral agreements with suppliers, storage capabilities should be realized for excessive natural gas supply. Turkeys average growth rate of electricity production is 8,1% while installed capacity has 8,5% for the last 25 years. The present total installed capacity is 39 020 MW in which renewables has a share of 34%. Total electricity production was 162 TWh in 2005 of which 75,4% was supplied by thermal power plants. Share of natural gas is 44% of the annual electricity production. Considering the present power plants and the ones under construction, electricity supply and demand will be in balance till the year of 2010 (with high demand scenario) or 2015 (with low demand scenario). Nuclear power is being considered for electricity supply security after 2015. But, the general approach for supply security is first to develop the domestic coal reserves, renewable energy resources.

    Europe is one of the world leaders in nuclear technology advancement. The development of spent fuel reprocessing is but one example of this. This process continues today with the development by France and Germany of the European Pressurised-Water Reactor. Nuclear research and development work is continuing in Europe, and must be continued in the future, if Europe is to retain its world leadership position in the technological field and on the commercial front. If we look at the benefits, which nuclear energy has to offer, in economic and environmental terms, 1 support the view that nuclear is an energy source whose time has come again. This is not some fanciful notion or wishful thinking. There is clear evidence of greater long-term reliance on nuclear energy. Perhaps we do not see new nuclear plants springing up in Europe, but we do see ambitious nuclear power development programmes underway in places like China, Japan and Korea. Closer to home, Finland is seriously considering the construction of a new nuclear unit. Elsewhere, in Europe and the US, we see a growing trend towards nuclear plant life extension and plant upgrades geared towards higher production capacity. These are all signs that nuclear will be around for a long time to come and that nuclear will indeed have a future

    This report was prepared in response to a request by the US Department of energy (DOE). The principal objectives of the study were to assess the current DOE coal program vis-a-vis the provisions of the Energy Policy Act of 1992 (EPACT), and to recommend the emphasis and priorities that DOE should consider in updating its strategic plan for coal. A strategic plan for research, development, demonstration, and commercialization (RDD and C) activities for coal should be based on assumptions regarding the future supply and price of competing energy sources, the demand for products manufactured from these sources, technological opportunities, and the need to control the environmental impact of waste streams. These factors change with time. Accordingly, the committee generated strategic planning scenarios for three time periods: near-term, 1995--2005; mid-term, 2006--2020; and, long-term, 2021--2040. The report is divided into the following chapters: executive summary; introduction and scope of the study; overview of US DOE programs and planning; trends and issues for future coal use; the strategic planning framework; coal preparation, coal liquid mixtures, and coal bed methane recovery; clean fuels and specialty products from coal; electric power generation; technology demonstration and commercialization; advanced research programs; conclusions and recommendations; appendices; and glossary. 174 refs.

    The 2012 Global Energy Competitiveness Index, a survey jointly conducted by Institut Choiseul and KPMG, is the first of its kind. It ranks 146 countries, grouping them into 5 categories ranging from the best performers to under-performers. The first edition of this annual study ranks the countries surveyed not only by continent but also according to the quality of their energy mix, electricity access and availability levels and the compatibility of their energy policies with environmental challenges. The governing bodies of the countries in the panel (relevant ministries and regulatory authorities) can gain much from this decision-making support tool that fosters dialogue on energy-related issues. The targeted audience also includes industry professionals, NGOs, international organisations and other economic players such as banks, consulting firms and specialist commercial law firms commercial law firms. Europe is by far the best performing continent ahead of the best performing continent, ahead of the Americas and Americas and even further ahead of Asia/Oceania and Africa. Generally speaking, the Nordic countries are among the best performers: Norway, Canada, Iceland, Denmark, Sweden and Finland rank, in this order, in the global Top 10. Four EU countries are among the global Top 10 (Denmark, Sweden, Finland and France) and five others (the United Kingdom, Austria, Germany, Slovakia and Spain) are in the Top 20. Surprisingly, Colombia stood out as the fifth most competitive country in terms of energy. Its outstanding performance is due to a strong energy mix (ranked second worldwide) and an energy strategy compatible with today's key environmental challenges. The apparent domination of Northern-hemisphere countries needs to be considered in conjunction with the results achieved by the other Seeming domination of be considered in conjunction with the results achieved by the other countries with regard to their energy mix and the environmental compatibility of

    In this chapter, the authors present scenarios of potential change in energy intensities in the OECD countries and in the Soviet Union. These scenarios are meant to illustrate how intensities might evolve over the next 20 years given different conditions with respect to energy prices, energy-efficiency policies, and other key factors. Changes in intensity will also be affected by the rates of growth and stock turnover in each sector. They have not tried to forecast how activity levels and structure will evolve. However, the OECD scenarios assume a world in which GDP averages growth in the 2-3%/year range, with some differences among countries. For the Soviet Union, the degree and pace of intensity decline will be highly dependent on the success of the transition to a market economy; each scenario explicitly envisions a different degree of success. They have not constructed comparable scenarios for the developing countries. The scenarios presented in this chapter do not predict what will happen in the future. They believe, however, that they illustrate a plausible set of outcomes if energy prices, policies, programs, and other factors evolve as described in each case. With higher energy prices and vigorous policies and programs, intensities in the OECD countries in 2010 could be nearly 50% less on average than the level where trends seem to be point. In the former Soviet Union, a combination of rapid, successful economic reform and extra effort to improve energy efficiency might result in average intensity being nearly 40% less than in a slow reform case. And in the LDCs, a mixture of sound policies, programs, and energy pricing reform could also lead to intensities being far lower than they would be otherwise. 8 refs., 10 figs., 1 tab

A linearized inverse method fits a lithospheric reference model to reproduce measured data sets, such as topography and surface heat flow, while assuming isostasy and solving the steady state heat equation. A FEM code solves the equations of equilibrium...

  11. Global wind energy outlook 2008

    International Nuclear Information System (INIS)

    2008-10-01

    An overview is given of the global potential of wind power up to 2050. This potential could play a key part in achieving a decline in emissions by 2020, which the IPCC indicates is necessary to avoid the worst consequences of climate change. By 2020, wind power could save as much as 1.5 billion tonnes of CO2 every year, which would add up to over 10 billion tonnes in this timeframe. The report also explains how wind energy can provide up to 30% of the word's electricity by the middle of the century. More importantly, wind power could save as much as 1.5 billion tonnes of CO2 every year by 2020. GWEO 2008 explores three different scenarios for wind power: a Reference scenario based on figures from the International Energy Agency (IEA); a Moderate version which assumes that current targets for renewable energy are successful; and an Advanced Scenario which assumes that all policy options in favour of renewables have been adopted. These are then set against two demand projections for global energy demand. Wind energy has already become a mainstream power generation source in many regions around the world, and it is being deployed in over 70 countries. In addition to environmental benefits, wind energy also provides a sustainable answer to increasing concerns about security of energy supply and volatile fossil fuel prices. Moreover, wind energy is becoming a substantial factor in economic development, providing more than 350,000 'green collar' jobs today both in direct and indirect employment. By 2020, this figure is projected to increase to over 2 million

    In the decades following India's independence from British rule in 1947, the West's image of India was summarized in three simple cliches: the world's largest democracy, an impoverished continent, and economic growth hampered by a fussy bureaucracy and the caste system, all in a context of a particular religion. These cliches are perhaps one of the reasons that the success of India's green revolution was recognized so late, a revolution that allowed the country to develop its agricultural sector and to feed its population. Since the 1990's, the easing of planning constraints have liberated the Indian economy and allowed it to embark on a more significant path of growth. New cliches have begun to replace the old: India will become a second China and, lagging by 10 to 20 years, will follow the same trajectory, with its development marked more by services and the use of renewable energy. However, these trends will not prevent primary energy demand from exploding. On the contrary, India faces difficult choices on how it increases clean, secure, affordable energy to all its citizens. Many of the choices are the same as found elsewhere, but on a scale matched only by China. The IFRI European Governance and Geopolitics of Energy Project intends this study to deepen public understanding of the magnitude of India's challenges. Various aspects of the serious energy problems are studied throughout this monograph. The authors have written freely on these matters without attempting to reconcile their different viewpoints. The first chapter, by Maite Jaureguy-Naudin and Jacques Lesourne, presents an overview of India's present and future energy system. The authors follow a prudent but realistic view of India's future. The second chapter, by Jean-Joseph Boillot, a French expert on India who has published several books and articles on this subject, and Nicolas Autheman, research fellow, describes in greater detail the specifics of India's economy and the actors who are now present

  13. Uranium, its impact on the national and global energy mix; and its history, distribution, production, nuclear fuel-cycle, future, and relation to the environment

    Finch, Warren Irvin

    1997-01-01

    The many aspects of uranium, a heavy radioactive metal used to generate electricity throughout the world, are briefly described in relatively simple terms intended for the lay reader. An adequate glossary of unfamiliar terms is given. Uranium is a new source of electrical energy developed since 1950, and how we harness energy from it is explained. It competes with the organic coal, oil, and gas fuels as shown graphically. Uranium resources and production for the world are tabulated and discussed by country and for various energy regions in the United States. Locations of major uranium deposits and power reactors in the United States are mapped. The nuclear fuel-cycle of uranium for a typical light-water reactor is illustrated at the front end-beginning with its natural geologic occurrence in rocks through discovery, mining, and milling; separation of the scarce isotope U-235, its enrichment, and manufacture into fuel rods for power reactors to generate electricity-and at the back end-the reprocessing and handling of the spent fuel. Environmental concerns with the entire fuel cycle are addressed. The future of the use of uranium in new, simplified, 'passively safe' reactors for the utility industry is examined. The present resource assessment of uranium in the United States is out of date, and a new assessment could aid the domestic uranium industry.

    1982-01-01

    With this report the German Federal Diet submits the final results of the opinion-forming and decision-making process concerning the recommendations made by the investigation committee 'Future Nuclear Energy Policy' in June 1980. By means of this report it is intended to point out to an interested public the difficult and time-consuming process of parliamentary decision-making. This report is also to be seen as the final opinion delivered on the recommendations made by the investigation committee. The recommendations were to continue to pursue the peaceful use of nuclear energy, the necessity and technical justifiability of which had basically been approved by all parliamentary groups. In view of the import of the subject and in recognition of the work done by the investigation committee, the German Parliament has thoroughly discussed the report and has reviewed the analyses and recommendations in conjunction with other political fields to be considered. One part of the recommendations was taken up almost unanimously. As far as the safety of nuclear installations is concerned, the investigation committee could not submit any new findings which would give reasons for modifying the hitherto positive assessment of the safety of nuclear installations. The recommendations of the investigation committee mainly referred to the decision-making process in the field of energy policy which will effect the next decade. What fundamental decisions are to be made until when was pointed out as well as the findings and experience to be made until then. (orig./HP) [de

    The National Energy Board periodically publishes a long-term energy and demand report as part of an ongoing monitoring program. The next report is planned for release in 2007. This background document provided background information to ensure that consultation participants have a common understanding of key issues to be addressed during the cross-country consultations that have been planned before the release of the final version of the report. An outline of the proposed analytical approach was presented, as well as details of major assumptions and scenario storylines. Scenario themes included: economic, energy and environmental sustainability; a security-focused world shaped by war and civil strife; and strong global economic growth fueled by the rapid growth of the Chinese and Indian economies. A methodology overview was provided as well as a reference case. Issues related to energy supply included oil; natural gas liquids; natural gas; and electricity. Issues related to energy demand included the residential sector; the commercial sector; the industrial sector; and the transportation sector. Historical trends and forecasts were outlined using the macroeconomic variable of interest. Supply, demand, and supporting infrastructure across all energy forms within a North American and global context were considered. The impact of environmental management strategies were reviewed, as well as the role of the government in shaping policies. It was concluded that the purpose of the final report is to serve as a standard of references for parties interested in Canadian energy issues and trends as well as to inform decision makers of key risks and uncertainties facing the energy future.9 tabs., 1 fig

    The climate change debate is really about economics, and reducing greenhouse gas (GHG) emissions and climate change potential at a reasonable and acceptable cost for everyone. In this paper, we examine the major economic factors behind defining climate change policies that relate to reducing GHG emissions, and the value to be placed on CO 2 . We examine the impacts and the 'cost of carbon' based on the studies of GHG reduction strategies in the US and the European Union (EU). We show that a series of self-defeating assumptions have been used in the latest analyses regarding relative future energy and power costs, and hence future GHG emissions. We estimate: the 'natural value' of GHG emissions based on world economic factors, the value of electricity and energy based on world data, the cost advantage of using a given new technology, and the value of avoided GHG emissions in future global and national climate change projections. The use of electricity is shown to be key in aiding economic growth for the entire world. Using the latest Intergovernmental Panel on Climate Change (IPCC) 2000 climate change projections as a base, we reflect the impacts of differing energy prices on future global climate conditions and GHG reductions. We conduct a similar analysis for Canada using the latest 'Energy in Canada 2000' projections. We show how the use of advanced technology for the traditional production of electricity, and for hydrogen-based transportation fuels, can stabilize global emissions and assist in managing adverse climate change conditions without causing economic penalties. The method we develop is sufficiently general that it can be used for valuing the economic impact of the emission reductions for any technology. We estimate the embedded value and potential economic benefit of nuclear technology and electric contribution for both the world economy to 2100, and for the latest projections for Canada to 2020.

    With population projections indicating continued growth during this century, socio-economic problems (e.g., water, food, and energy shortages) will be most likely to occur, especially if proper planning, development, and management strategies are not adopted. In the present study, firstly, we explore the vital role of dams in promoting economic growth through analyzing the relationship between dams and Gross Domestic Product (GDP) at both global and national scales. Secondly, we analyze the current situation of global water scarcity based on the data representing water resources availability, dam development, and the level of economic development. Third, with comprehensive consideration of population growth as the major driving force, water resources availability as the basic supporting factor, and topography as the important constraint, this study addresses the question of dam development in the future and predicts the locations of future dams around the world.

    2004-01-01

    Nuclear energy, which exhibits a unique combination of environmental and sustainable attributes, appears strongly positioned to play a much larger and more pivotal role in the mix of future global energy supplies than it has played in the past. Unfortunately, enrolment patterns in nuclear engineering programmes have seriously eroded over the past decade - causing alarmingly low enrolment levels in many countries by the turn of the century and a sobering concern that the nuclear manpower pipeline cannot keep up with the emerging needs of the nuclear industry. On the positive side, enrolment patterns within the United States are now generally on the rise, at least at the undergraduate level. A few of the particularly successful efforts initiated by various sectors of the U.S. nuclear infrastructure to stimulate this rebound are shared in this paper with the hope that some of them might be beneficially employed in other global settings.

    The primary objective of this research was to develop a forefront analysis tool for application to enhance understanding of long-term, global, nuclear-energy and nuclear-material futures. To this end, an existing economics-energy-environmental (E 3 ) model was adopted, modified, and elaborated to examine this problem in a multi-regional (13), long-term (approximately2,100) context. The E 3 model so developed was applied to create a Los Alamos presence in this E 3 area through ''niche analyses'' that provide input to the formulation of policies dealing with and shaping of nuclear-energy and nuclear-materials futures. Results from analyses using the E 3 model have been presented at a variety of national and international conferences and workshops. Through use of the E 3 model Los Alamos was afforded the opportunity to participate in a multi-national E 3 study team that is examining a range of global, long-term nuclear issues under the auspices of the IAEA during the 1998-99 period . Finally, the E 3 model developed under this LDRD project is being used as an important component in more recent Nuclear Material Management Systems (NMMS) project

  2. Global warming from an energy perspective

    1991-01-01

    Global climate change and energy are integrally related. The majority of greenhouse gas emissions are the result of energy production and use; at the same time, warming will affect energy patterns in California through physical increases in energy demand, physical changes in energy supply, and changes in both energy end-use patterns and supplies resulting from climate-change policies. There seems to be a growing political consensus that the world (as well as the state) needs to act soon to minimize further commitment to future warming. While California is not likely to experience the physical changes resulting from a warmer climate for years or perhaps decades, policy responses to the warming issue may cause more immediate impacts. This chapter will discuss how policy response to potential warming may be the most significant early impact of the issue on California's energy system. Makers of energy policy face the dilemma of deciding how to respond to the climate warming issue in the face of scientific uncertainties about its timing and seriousness. The chapter will conclude by presenting a conceptual framework for dealing with this dilemma, along with general recommendations for action

    2009-01-01

    This article conceptualizes the energy problems facing society from a global governance perspective. It argues that a notion of 'global energy governance,' taken to mean international collective action efforts undertaken to manage and distribute energy resources and provide energy services, offers a meaningful and useful framework for assessing energy-related challenges. The article begins by exploring the concepts of governance, global governance, and global energy governance. It then examines some of the existing institutions in place to establish and carry out rules and norms governing global energy problems and describes the range of institutional design options available to policymakers. It briefly traces the role of a selection of these institutions, from inter-governmental organizations to summit processes to multilateral development banks to global action networks, in responding to energy issues, and points out their strengths and weaknesses. The article concludes by analyzing how the various approaches to global governance differ in their applicability to addressing the conundrums of global energy problems.

    Economic development translates into growing demand for energy services. However, more than 1.6 billion people at present still do not have access to modern energy services. Continued population growth compounds this demand for energy, which is central to achieving sustainable development goals. Poverty eradication calls for affordable energy services. There is a need to minimize health and environmental impacts of energy use. Nuclear power's share of global electricity rose to 16% in 1986. Near the end of the 1980s growth stagnated. Regulatory interventions often stretched out licensing times and increased costs. Inflation and rising energy costs resulting from the oil shocks of 1973 and 1979 brought about a significant drop in electricity demand and raised the costs of capital intensive power plants, like nuclear power plants. Some utilities found the regulatory and transaction costs of nuclear power simply too high to manage costs-effectively. The 1979 Three Mile Island accident and the Chernobyl accident in 1986 retarded the expansion of nuclear power. The electricity market liberalization and privatization exposed excess capacity, pushed electricity prices lower and made power plant investments more risky. Other things being equal, nuclear power's front-loaded cost structure was a disadvantage in markets that emphasize short term profits and rapid returns. In the 1990s, growth in nuclear electricity generation exceeded the growth in nuclear capacity as management efficiencies and technological advances progressively raised the average energy availability of the world's nuclear plants. The energy availability factor measures the percentage of time that a power reactor is available to generate electricity, rather than being shutdown for refuelling, maintenance and other reasons. The global average for nuclear power reactors has risen from 67% in 1990 to 81% in 2004. This increase is equivalent to the addition of 34 new 1000 MW reactors. Electricity generation

    A survey of the base-load energy sources available to humans is presented, starting from the point of view that all energy used is ultimately derived from nuclear processes within the sun. Specific note is made of European energy options, noting the large dependence on imported oil. Detailed exploration of available nuclear fuel resources is carried out, with attention given to fission, fusion, and breeder reactor plants and to the state-of-the-art and technology for each. The problems of nuclear waste disposal are discussed, and long term burial in salt domes is outlined as a satisfactory method of containing the materials for acceptable periods of time. The CO/sub 2/ greenhouse effect hazards caused by increased usage of coal-derived fuels are considered and precautions to be taken on a global scale to ameliorate the warming effects are recommended. The limitations to hydropower are examined, as are those of tidal power. Solar cells are projected to be produced in GW quantities by the year 2000, while wind-derived electricity is predicted to provide a minimum of 5% of the world energy needs in the future.

  7. The future of nuclear energy in Europe

    Schmidt-Kuester, W.J.

    2000-01-01

    Are concerns about global warming of the Earth's atmosphere going to rekindle interest in nuclear power and in building new nuclear power plants in Europe? As a consequence of the discussions about the climate, the use of nuclear power as an important energy source is currently being re-evaluated, finds Dr. Wolf-J. Schmidt-Kuester, Secretary General of FORATOM, the European Atomic Forum, headquartered in Brussels. In his article, he argues that a renaissance of nuclear power will be possible also in Europe once politics supports resuming an unbiased discussion of all topics associated with the energy problem. Europe must face two problems in the energy sector for which solutions must be found: the growing dependence on fossil energy resources, and the need to curb greenhouse gas emissions, especially those of carbon dioxide. Nuclear power is already making a sizable contribution towards the solution of these problems, but its future potential has hardly been tapped. Public acceptance of nuclear power shows that the intention to opt out of the peaceful uses of nuclear power is not based on an identical attitude of the public, but is motivated politically, finding only little public support, as in the cases of Sweden and Germany.

    The manner in which the world has conducted itself in exploiting energy resources so far particularly in the post industrial revolution period, is now looming as one of the greatest challenges to the sustainability of development or even sustainability of life. Global climate change is no more a perceived threat, it is now a reality and we are not in a position to engage ourselves to debate on the issue. It is in fact a little late in taking the right corrective action if we have any concern for our future generations. The efforts of the scientists and engineers are to gradually replace the energy from burning of carbonaceous material to clean and intense source of energy i.e. nuclear fission and fusion

  10. Alternative Energy Development and China's Energy Future

    Energy Technology Data Exchange (ETDEWEB)

    Zheng, Nina; Fridley, David

    2011-06-15

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

    Since unification, the former German Democratic Republic has had to face major changes, one of which concerns the energy supply system. A secure energy supply system is an absolute requirement for the political and economical development of this Republic. Its former strategy of 'autarkical' energy supply until the end of 1989 was one of the factors which led to an economic downfall. This essay gives an overview of the major structural changes to the economy which have occurred since unification. First, the former energy situation is described and the status quo analyzed. Then, efforts in reorganizing the present energy supply system are outlined. Finally, new perspectives and strategies are described. The aspects taken into consideration include: energy price deregulation; European fossil fuel marketing trends; investments for the build up of an efficient energy supply system; and the creation of surcharges for environmental pollution abatement, in particular, the reduction of carbon and sulfur dioxide emissions.

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

  5. Exploring the undulating plateau: the future of global oil supply.

    Science.gov (United States)

    Jackson, Peter M; Smith, Leta K

    2014-01-13

    In this paper, we analyse the factors that will influence long-term oil supply and describe the future form of the global oil supply profile as an 'undulating plateau' rather than an irreversible, short-term peak or an ever upward trend of increasing production. The ultimate transition from a world of relatively plentiful and cheap oil to one of tight supply and high cost will be slow and challenging. An understanding of the signposts for the future path of supply and the drivers of that profile will be critical to managing the transition. The ultimate form of the global supply curve may well be dictated by demand evolution rather than a limited resource endowment in the longer term. Several factors will probably control future global oil supply. We believe that the scale of global oil resource will not constitute a physical supply limit for at least the next two or three decades. However, all categories of oil resources are already more expensive to develop than in the past, requiring high oil prices to stimulate supply growth. Lower rates of oil demand growth relative to economic growth, combined with more challenging supply growth, will probably lead to an undulating plateau sometime after 2040, with demand from non-Organization for Economic Cooperation and Development states continuing to dominate. Upstream investment requirements and oil price volatility will increase towards and beyond the undulating production plateau. In this new world, high oil prices will induce demand destruction, fuel substitution and ever increasing energy efficiency. As we discuss below, the fundamental differences between the IHS Cambridge Energy Research Associates' (IHS CERA) view of the future of oil supply and many peak oil supply models are the timing of the onset of a dramatic slowdown in the rate of growth of supply and the existence or otherwise of a production plateau. We do not dispute that supply will plateau and eventually fall; the question is when, how and at what price

  8. Hydrogen energy strategies and global stability and unrest

    International Nuclear Information System (INIS)

    Midilli, A.; Dincer, I.; Rosen, M.A.

    2004-01-01

    This paper focuses on hydrogen energy strategies and global stability and unrest. In order to investigate the strategic relationship between these concepts, two empirical relations that describe the effects of fossil fuels on global stability and global unrest are developed. These relations incorporate predicted utilization ratios for hydrogen energy from non-fossil fuels, and are used to investigate whether hydrogen utilization can reduce the negative global effects related to fossil fuel use, eliminate or reduce the possibilities of global energy conflicts, and contribute to achieving world stability. It is determined that, if utilization of hydrogen from non-fossil fuels increases, for a fixed usage of petroleum, coal and natural gas, the level of global unrest decreases. However, if the utilization ratio of hydrogen energy from non-fossil fuels is lower than 100%, the level of global stability decreases as the symptoms of global unrest increase. It is suggested that, to reduce the causes of global unrest and increase the likelihood of global stability in the future, hydrogen energy should be widely and efficiently used, as one component of plans for sustainable development.

    2012-07-01

    Brazil is the 10th largest energy consumer in the world and the third largest in the Western Hemisphere, behind the United States and Canada. Total primary energy consumption in Brazil has increased significantly in recent years; and over the past decade, Brazil has made great strides in increasing its total energy production, particularly oil. Brazil has the second-largest crude oil reserves in South America (behind Venezuela), and is one of the fastest growing oil producers in the world. According to United States Energy Information Administration (EIA), Brazil had 12.2 billion barrels of proven oil reserves in 2008. In 2007, Brazil's state owned Petroleo Brasileiro S.A. (PETROBRAS) announced that it had discovered an estimated 5-8 billion barrels of recoverable reserves (including both oil and natural gas) in the Tupi field, located in the Santos Basin. In 2008, subsequent discoveries were announced, to include Jupiter and Carioca (aka Sugar Loaf). Although PETROBRAS has yet to confirm the size of the discoveries, some industry analysts estimate the total extent of recoverable oil and natural gas reserves in the entire pre-salt layer have approached 40 to 80 billion barrels of oil equivalent. The reserves occur below a salt zone that is estimated to be 7,000 meters below the ocean surface. However, Brazil faces many challenges to recover the hydrocarbons to include technical, political, fiscal, and infrastructure hurdles. In spite of the challenges ahead, these discoveries transformed the nature and focus of Brazil's oil industry, economy, and future; and the potential impact of the pre-salt discoveries upon world oil markets is vast. The purpose of this paper is to discuss how the recent discoveries will affect Brazil's future and the impact it will have on the global energy world. (author)

    The elements of a methodology to be employed by the global community to investigate the consequences of global environmental change upon future generations and global ecosystems are outlined in this paper. The methodology is comprised of two major components: A possible future worlds model; and a formal, citizen-oriented process to judge whether the possible future worlds potentially inheritable by future generations meet obligational standards. A broad array of descriptors of future worlds can be encompassed within this framework, including survival of ecosystems and other species and satisfaction of human concerns. The methodology expresses fundamental psychological motivations and human myths journey, renewal, mother earth, and being-in-nature-and incorporates several viewpoints on obligations to future generations-maintaining options, fairness, humility, and the cause of humanity. The methodology overcomes several severe drawbacks of the economic-based methods most commonly used for global environmental policy analysis.

    Technological choices largely determine the long-term characteristics of industrial society, including impacts on the natural environment. However, the treatment of technology in existing models that are used to project economic and environmental futures remains highly stylized. Based on work over two decades at IIASA, we present a useful typology for technology analysis and discuss methods that can be used to analyze the impact of technological changes on the global environment, especially global warming. Our focus is energy technologies, the main source of many atmospheric environmental problems. We show that much improved treatment of technology is possible with a combination of historical analysis and new modeling techniques. In the historical record, we identify characteristic 'learning rates' that allow simple quantified characterization of the improvement in cost and performance due to cumulative experience and investments. We also identify patterns, processes and timescales that typify the diffusion of new technologies in competitive markets. Technologies that are long-lived and are components of interlocking networks typically require the longest time to diffuse and co-evolve with other technologies in the network; such network effects yield high barriers to entry even for superior competitors. These simple observations allow three improvements to modeling of technological change and its consequences for global environmental change. One is that the replacement of long-lived infrastructures over time has also replaced the fuels that power the economy to yield progressively more energy per unit of carbon pollution - from coal to oil to gas. Such replacement has 'decarbonized' the global primary energy supply 0.3% per year. In contrast, most baseline projections for emissions of carbon, the chief cause of global warming, ignore this robust historical trend and show Iittle or no decarbonization. A second improvement is that by incorporating learning curves and

    Nuclear energy plays a major role in the French economy because of the lack of fossil fuels on the French territory. About 75% of the French electric power is of nuclear origin. This paper gives an analysis of the French public attitude about nuclear energy and the methods used by the nuclear industrialists to better the electro-nuclear image. Communication, advertising and transparency are the best attitudes for a suitable public information and are necessary to reduce the public anxiety after the Chernobyl accident. Television advertising, magazines and organized visits of nuclear installations have allowed to explain the interest of nuclear energy in the environmental reduction of pollutants. However, public information must include the topic about nuclear wastes to remain credible. (J.S.)

    Coal is no longer considered as a 'has been' energy source. The production and demand of coal is growing up everywhere in the world because it has some strategic and technological advantages with respect to other energy sources: cheap, abundant, available everywhere over the world, in particular in countries with no geopolitical problems, and it is independent of supplying infrastructures (pipelines, terminals). Its main drawback is its polluting impact (dusts, nitrogen and sulfur oxides, mercury and CO 2 ). The challenge is to develop clean and high efficiency coal technologies like supercritical steam power plants or combined cycle coal gasification plants with a 50% efficiency, and CO 2 capture and sequestration techniques (post-combustion, oxy-combustion, chemical loop, integrated gasification gas combined cycle (pre-combustion)). Germany, who will abandon nuclear energy by 2021, is massively investing in the construction of high efficiency coal- and lignite-fired power plants with pollution control systems (denitrification and desulfurization processes, dust precipitators).

    Recent national focus on the value of increasing our supply of indigenous, renewable energy underscores the need for reevaluating all alternatives, particularly those that are large and welldistributed nationally. This analysis will help determine how we can enlarge and diversify the portfolio of options we should be vigorously pursuing. One such option that is often ignored is geothermal energy, produced from both conventional hydrothermal and Enhanced (or engineered) Geothermal Systems (EGS). An 18-member assessment panel was assembled in September 2005 to evaluate the technical and economic feasibility of EGS becoming a major supplier of primary energy for U.S. base-load generation capacity by 2050. This report documents the work of the panel at three separate levels of detail. The first is a Synopsis, which provides a brief overview of the scope, motivation, approach, major findings, and recommendations of the panel. At the second level, an Executive Summary reviews each component of the study, providing major results and findings. The third level provides full documentation in eight chapters, with each detailing the scope, approach, and results of the analysis and modeling conducted in each area.

    This article conceptualizes the energy problems facing society from a global governance perspective. It argues that a notion of 'global energy governance,' taken to mean international collective action efforts undertaken to manage and distribute energy resources and provide energy services, offers a meaningful and useful framework for assessing energy-related challenges. The article begins by exploring the concepts of governance, global governance, and global energy governance. It then examines some of the existing institutions in place to establish and carry out rules and norms governing global energy problems and describes the range of institutional design options available to policymakers. It briefly traces the role of a selection of these institutions, from inter-governmental organizations to summit processes to multilateral development banks to global action networks, in responding to energy issues, and points out their strengths and weaknesses. The article concludes by analyzing how the various approaches to global governance differ in their applicability to addressing the conundrums of global energy problems. (author)

    Fusion implementation scenarios for the US have been developed. The dependence of these scenarios on both the fusion development and implementation paths has been assessed. A range of implementation paths has been studied. The deployment of CANDU fission reactors in Canada and the deployment of fission reactors in France have been assessed as possible models for US fusion deployment. The waste production and resource (including tritium) needs have been assessed. The conclusion that can be drawn from these studies is that it is challenging to make a significant impact on energy production during this century. However, the rapid deployment of fission reactors in Canada and France support fusion implementation scenarios for the US with significant power production during this century. If the country can meet the schedule requirements then the resource needs and waste production are found to be manageable problems

    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)

    Larsen, Hans; Soenderberg Petersen, L. (eds.)

    2008-10-15

    This Risoe Energy Report, the seventh of a series that began in 2002, takes as its point of reference the recommendations of the Intergovernmental Panel on Climate Change (IPCC) in 2007. The IPCC states that if anticipated climate change is to remain in the order of 2 to 3 degrees centigrades over the next century, the world's CO{sub 2} emissions would have to peak within the next 10-15 years and ultimately be reduced to approximately 50% of their present level by the middle of the century. The IPCC states further that this would be possible, provided that serious action is taken now. The different regions and countries of the world are in various states of development, and hence have different starting points for contributing to these reductions in CO{sub 2} emissions. This report presents state-of-the-art and development perspectives for energy supply technologies, new energy systems, end-use energy efficiency improvements and new policy measures. It also includes estimates of the CO{sub 2} reduction potentials for different technologies. The technologies are characterized with regard to their ability to contribute either to ensuring a peak in CO{sub 2} emissions within 10-15 years, or to long-term CO{sub 2} reductions. The report outlines the current and likely future composition of energy systems in Denmark, and examines three groups of countries: i) Europe and the other OECD member nations; ii) large and rapidly growing developing economies, notably India and China; iii) typical least developed countries, such as many African nations. The report emphasises how future energy developments and systems might be composed in these three country groupings, and to what extent the different technologies might contribute. The report addresses the need for research and demonstration together with market incentives, and policy measures with focus on initiatives that can promote the development towards CO{sub 2} reductions. Specifically, the report identifies system

    Hart, R.G.

    1977-08-01

    An attempt is made to put the future energy scene in perspective by quantitatively examining energy resources, energy utilization and energy costs. Available data on resources show that conventional oil and gas are in short supply and that alternative energy sources are going to have to replace oil and gas in the not too distant future. Cost/applications assessments indicate that a mix of energy sources are likely to best meet our energy needs of the future. Hydro, nuclear and coal are all practical alternatives for meeting electrical needs and electricity is a practical alternative for space heating. Coal appears to be the most practical alternative for meeting much of the industrial energy need and frontier oil or oil from the tar sands appear to be the most practical alternatives for meeting the transportation need. Solar energy shows promise of meeting some of the space heating load in Canada if economical energy storage systems can be developed. The general conclusion is that the basic energy problem is energy conversion. (author)

    Koughnett, K. Van

    2003-01-01

    This presentation provided a brief history of wind power through the ages, and culminated with a look at installed capacity in 2002. Vision Quest has been in the wind power business since 1980, and the first turbines were installed in 1997. The company operates 40 per cent of Canada's wind capacity. Vision Quest became part of TransAlta in December 2002, the largest non-regulated electric generation and marketing company in Canada. The reasons for investing in wind power were briefly reviewed. The author then examined the physics of wind power and wind energy resources. The key resource issues were identified as being resource availability and constancy, which is similar to oil and gas exploration. Utility scale turbines were described. The pros and cons of larger turbines were compared, and it was shown that larger turbines offer better economics, a higher capacity factor and fewer turbines to permit. Manufacturers are focused on larger machines for offshore. The various permitting authorities and their areas of responsibility were listed, from municipal, provincial and federal levels. The key drivers are: wind speed, installed cost of equipment, revenue, operating expense, and financial expense. Project risks include: power purchase agreements, technology risk, financial risk, construction risk, regulation, operating risks, dependence on third parties, and reliance on advisors. Some of the challenges facing Vision Quest are being early, permitting, electric grid interconnection, openness of markets, market supply, demand forces, and getting capital costs down. tabs., figs

    This paper tries to state energy situation and then energy policy globally in economic view and then offer the practical solution. Besides above questions, the most important questions that will be answered are: What is the energy position, in economic view? and what is the most important priority among environmental issues? According to present conditions and environmental challenges what is the way map for energy supply? Is the priority for environment and energy with an economic sight, in present and future, same as the past? (Author)

    2011-01-01

    The Arctic has a substantial share of global petroleum resources, but at higher costs than in most other petroleum provinces. Arctic states and petroleum companies are carefully considering the potential for future extraction in the Arctic. This paper studies the oil and gas supply from 6 arctic regions during 2010-2050 along with global economic growth and different assumptions regarding petroleum prices and resource endowments. Supply is calculated based on a global model of oil and gas mar...

    The global energy confinement behaviour of mixed Ohmic/Lower Hybrid driven Tore Supra plasmas has been analysed at various densities. In contradiction with L-mode ITER scaling law, this analysis indicates that the global energy confinement time depends strongly on the plasma density and the isotopic dependence seems not to be observed. The thermal electron energy content of steady-state discharges is in good agreement with the offset linear Rebut-Lallia scaling law. During current ramp experiments, the global energy confinement time was found to depend on the internal self-inductance (li). Improved confinement has been obtained for a steady-state 0.8 MA plasma where the plasma current profile is peaked by LH waves (li ∼1.8). In this case, the global confinement time is found to be about 40% higher than the value predicted by the Rebut-Lallia scaling law. (author) 3 refs., 6 figs

  3. Sustaining the future: the role of nuclear power in meeting future world energy needs

    International Nuclear Information System (INIS)

    Duffey, R.; Sun, Y.

    2003-01-01

    A description is given of recently informed analyses showing the potential that nuclear power has in meeting global energy demands. For both the electricity and transportation sectors, we can quantify the beneficial effects on the environment, and we show how nuclear power deserves credit for its role in assisting future world energy, environmental and economic sustainability. The continuing expansion of the world's and Asia's energy needs, coupled with the need to reduce greenhouse gas (GHG) and other emissions, will require new approaches for large scale energy production and use. This is particularly important for China and Asia with respect to meeting both the energy demand and sustainability challenges. We show and explore the role of nuclear power for large-scale energy applications, including electricity production and hydrogen for transportation. Advanced nuclear technologies, such as those like CANDU's next generation ACR, can meet future global energy market needs, avoid emissions, and mitigate the potential for global climate change. We use the latest IPCC Scenarios out to the year 2100 as a base case, but correct them to examine the sensitivity to large scale nuclear and hydrogen fuel penetration. We show a significant impact of nuclear energy on energy market penetration, and in reducing GHGs and other emissions in the coming century, particularly in the industrial developing world and in Asia. This is achieved without needing emissions credits, as are used or needed as economic support for other sources, or for subsidies via emissions trading schemes. Nuclear power offers the relatively emissions-free means, both to provide electricity for traditional applications and, by electrolytic production of hydrogen, to extend its use deep into the transportation sector. For the published IPCC Marker Scenarios for Asia we show the reduction in GHG emissions when electrolysis using electricity from nuclear power assists the introduction of hydrogen as a fuel

  4. Technology Learning Ratios in Global Energy Models

    International Nuclear Information System (INIS)

    Varela, M.

    2001-01-01

    The process of introduction of a new technology supposes that while its production and utilisation increases, also its operation improves and its investment costs and production decreases. The accumulation of experience and learning of a new technology increase in parallel with the increase of its market share. This process is represented by the technological learning curves and the energy sector is not detached from this process of substitution of old technologies by new ones. The present paper carries out a brief revision of the main energy models that include the technology dynamics (learning). The energy scenarios, developed by global energy models, assume that the characteristics of the technologies are variables with time. But this trend is incorporated in a exogenous way in these energy models, that is to say, it is only a time function. This practice is applied to the cost indicators of the technology such as the specific investment costs or to the efficiency of the energy technologies. In the last years, the new concept of endogenous technological learning has been integrated within these global energy models. This paper examines the concept of technological learning in global energy models. It also analyses the technological dynamics of the energy system including the endogenous modelling of the process of technological progress. Finally, it makes a comparison of several of the most used global energy models (MARKAL, MESSAGE and ERIS) and, more concretely, about the use these models make of the concept of technological learning.

  5. The G20 and the Future of Energy Governance

    Directory of Open Access Journals (Sweden)

    Tristram Sainsbury

    2016-03-01

    Full Text Available The fraught history of energy governance means that despite the oil shocks of the 1970s and ongoing resource price volatility, today there are no effective global mechanisms for cooperation between energy -producing and energy-consuming countries. Furthermore, there are two conflicting challenges at the heart of energy governance — ensuring energy access for all and transitioning to a low-carbon future. This article argues that the current global energy institutions are illequipped to provide the impetus for energy governance cooperation, and the solution will have to come from collective political will at the leader level. The Group of 20 (G20 could be part of the solution as the economic forum for the world’s largest advanced and emerging economies, including both energy producers and consumers. The article gives a brief history of energy governance and the institutions that emerged in the second half of the 20th century. It explores the strengths and weaknesses of each institution, including the well-established International Energy Agency (IEA and Organization of Petroleum Exporting Countries, as well as more recent players such as the International Energy Forum and the International Renewable Energy Agency. It goes on to explain how the lack of progress in reaching global solutions led to G20 interest in energy governance, and what that forum has achieved on energy cooperation so far, notably the G20 Principles on Energy Collaboration in 2014 and the meeting of G20 energy ministers in 2015. The article focuses mainly on how the G20 can progress the energy governance agenda, and what pragmatic options are available for the forum. In particular, it discusses how the G20 might spearhead reform of the IEA, support new initiatives and pursue a new platform for discussion within the G20.

  6. Food irradiation; Global aspects and future prospects

    Energy Technology Data Exchange (ETDEWEB)

    This paper reviews researches, commentaries, and conference and public records of food irradiation, published mainly during the period 1987-1989, focusing on the current conditions of food irradiation that may pose not only scientific or technologic problems but also political issues or consumerism. Approximately 50 kinds of food, although not enough to fill economic benefit, are now permitted for food irradiation in the world. Consumerism is pointed out as the major factor that precludes the feasibility of food irradiation in the world. In the United States, irradiation is feasible only for spices. Food irradiation has already been feasible in France, Hollands, Belgium, and the Soviet Union; has under consideration in the Great Britain, and has been rejected in the West Germany. Although the feasibility of food irradiation is projected to increase gradually in the future, commercial success or failure depends on the final selection of consumers. In this respect, the role of education and public information are stressed. Meat radicidation and recent progress in the method for detecting irradiated food are referred to. (N.K.) 128 refs.

  7. Future vaccines and a global perspective.

    Science.gov (United States)

    Katz, S L

    1997-12-13

    Advances in medical biotechnology mean that vaccines to prevent more than 75 infectious diseases are being or have been developed. Vaccination is unfortunately not reliant purely on biotechnology but also on politics and resources. Countries with the greatest demand for vaccines have the least ability to pay for or produce them. Health-care Infrastructure and diagnostic facilities also hamper immunisation projects in developing countries. Charitable organisations are relied on heavily to support such projects but the challenge to ensure all infants are immunised against the most common infections of childhood is still enormous. Difficulties that present themselves now should not prevent us looking into future possibilities such as immunisation during pregnancy and targeting of children for immunisation against sexually transmitted diseases. Other avenues for research are in administration of vaccines. A move to mucosal immunisation rather than use of the syringe and needle would be positive both economically and from the point of view of risk of needle contamination. Plant science may also provide a new vehicle for vaccines by engineering plants such as the banana tree to be naturally bioencapsulated vaccines. Prospects for control and eradication of infectious disease in the next century are certainly good.

    A sustained energy supply must do equal justice to the goals of economic, environmental and social compatibility. If there is a conflict of goals, the object cannot be to maximize one parameter from this bundle of goals; a balance should rather be sought between the set targets. An analysis of long-term projections for world energy supply shows that a greater convergence between expected developments and those considered necessary for climate policy reasons can only be reached by consistently pursuing all approaches suitable for achieving the targets set - e. g. in climate protection - at a minimum cost. The solution is not one of 'either - or' but of 'both - and'. (orig.)

There is not really a need or a disastrous culmination of the world energy supply situation to occur because, globally speakng, a large reservoir of energy resources is available. The problem rather lies in the structure of consumption in the industrialized countries, which is bound to lead to difficulties of supply soon, if the consumption of energy continues to rise. Changes in structure must be effected both on the supply and on the demand sides. (orig.) [de

    1997-12-31

    The global focus of the electric power industry was discussed. The shift from small regional monopolies to internationally competitive firms has been the driving force for change in industrial or market structures. The financial forces behind these changes were examined. The changes at the firm level and the implications of these changes for the North American market were explored. Changes in the North American market have influenced and are influenced by changes in international markets. The well established public and private monopolies in North America have been slow to welcome competition. However, with growing pressure from consumers, North America is becoming a major leader of global market trends. The following predictions regarding a deregulated electric power industry can be made with some confidence: (1) prices will fall, (2) customer choice will become a reality, (3) debt ridden public dinosaurs are not likely to survive, and (4) the same big firms in international markets will be the dominant players in the North American market. Canadian companies were warned that unless they can compete on equal terms with their American competitors, they may find themselves at a disadvantage in the new, competitive market.

    Current and future energy demands, end uses, and cost used to characterize typical applications and resultant services in the industrial sector of the United States and 15 selected states are examined. A review and evaluation of existing industrial energy data bases was undertaken to assess their potential for supporting SERI research on: (1) market suitability analysis, (2) market development, (3) end-use matching, (3) industrial applications case studies, and (4) identification of cost and performance goals for solar systems and typical information requirements for industrial energy end use. In reviewing existing industrial energy data bases, the level of detail, disaggregation, and primary sources of information were examined. The focus was on fuels and electric energy used for heat and power purchased by the manufacturing subsector and listed by 2-, 3-, and 4-digit SIC, primary fuel, and end use. Projections of state level energy prices to 1990 are developed using the energy intensity approach. The effects of federal and state industrial energy conservation programs on future industrial sector demands were assessed. Future end-use energy requirements were developed for each 4-digit SIC industry and were grouped as follows: (1) hot water, (2) steam (212 to 300/sup 0/F, each 100/sup 0/F interval from 300 to 1000/sup 0/F, and greater than 1000/sup 0/F), and (3) hot air (100/sup 0/F intervals). Volume I details the activities performed in this effort.

  16. Protecting global soil resources for future generations

    Montanarella, Luca

    2017-04-01

    The latest Status of World's Soil Resources report has highlighted that soils are increasingly under pressure by numerous human induced degradation processes in most parts of the world. The limits of our planetary boundaries concerning vital soil resources have been reached and without reversing this negative trend there will be a serious lack of necessary soil resources for future generations. It has been therefore of the highest importance to include soils within some of the Sustainable Development Goals (SDG) recently approved by the United Nations. Sustainable development can not be achieved without protecting the limited, non-renewable, soil resources of our planet. There is the need to limit on-going soil degradation processes and to implement extensive soil restoration activities in order to strive towards a land degradation neutral (LDN) world, as called upon by SDG 15. Sustainable soil management needs to be placed at the core of any LDN strategy and therefore it is of highest importance that the recently approved Voluntary Guidelines for Sustainable Soil Management (VGSSM) of FAO get fully implemented at National and local scale.Sustainable soil management is not only relevant for the protection of fertile soils for food production, but also to mitigate and adopt to climate change at to preserve the large soil biodiversity pool. Therefore the VGSSM are not only relevant to FAO, but also the the climate change convention (UNFCCC) and the biodiversity convention (CBD). An integrated assessment of the current land degradation processes and the available land restoration practices is needed in order to fully evaluate the potential for effectively achieving LDN by 2030. The on-going Land Degradation and Restoration Assessment (LDRA) of the Intergovernmental Platform for Biodiversity and Ecosystem Services (IPBES) will provide the necessary scientific basis for the full implementation of the necessary measures for achieving the planned SGS's relevant to land

    The global energy situation is rapidly changing. Global oil and gas trade is increasing, in an environment of rising prices, higher costs, greater environmental concerns, and growing security uncertainties. While predictions of shortages through depletion of oil and gas reserves are unfounded, the world must adapt to higher prices and changing trade patterns, as conventional reserves are increasingly being replaced un-conventional resources. Canada, drawing upon its vast natural resources and technological innovation, is positioned to be an even more important global energy leader in the 21st century. (author)

    and gas endowment estimates. Whereas petroleum resources in the world appear to be significant, certain countries such as the United States may run into import deficits, particularly oil imports from Mexico and natural gas from both Canada and Mexico. The new assessment has been used as the reference supply case in energy supply models by the International Energy Agency and the Energy Information Agency of the Department of Energy. Climate energy modeling groups such as those at Stanford University, Massachusetts Institute of Technology, and others have also used USGS estimates in global climate models. Many of these models using the USGS estimates converge on potential oil shortfalls in 2036-2040. However, recent articles using the USGS (2000) estimates suggest peaking of oil in 2020-2035 and peaking of non-OPEC (Organization of Petroleum-Exporting Countries) oil in 2015-2020. Such a short time framework places greater emphasis on a transition to increased use of natural gas; i.e., a methane economy. Natural gas in turn may experience similar supply concerns in the 2050-2060 time frame according to some authors. Coal resources are considerable and provide significant petroleum potential either by extracting natural gas from them, by directly converting them into petroleum products, or by utilizing them to generate electricity, thereby reducing natural gas and oil requirements by fuel substitution. Non-conventional oil and gas are quite common in petroleum provinces of the world and represent a significant resources yet to be fully studied and developed. Seventeen non-conventional AU including coal-bed methane, basin-center gas, continuous oil, and gas hydrate occurrences have been preliminarily identified for future assessment. Initial efforts to assess heavy oil deposits and other non-conventional oil and gas deposits also are under way.

    The goal of this conference was to analyse the future national and international problems arising with energy supplies with regard to the large mass flows and CO 2 flows involved in the use of nuclear energy. The following topics are dealt with: - nuclear energy, world-wide energy management and developments in Europe and Asia - disposal and ultimate waste disposal, plutonium management, an assessment of the Chernobyl accident 10 years on - new reactor developments in the energy mix - the costs arising with nuclear energy in the energy mix. In view of the demand made by climate researchers, to reduce CO 2 , and the additional construction work planned in the eastern and Asian areas, it will remain necessary for the Federal Republic of Germany,too, to maintain the know-how and technology for nuclear energy generation.

    A major challenge - some would argue, the major challenge facing our planet today - relates to the problem of anthropogenic-driven climate change and its inextricable link to our global society's present and future energy needs [King, D.A., 2004. Environment - climate change science: adapt, mitigate, or ignore? Science 303, 176-177]. Hydrogen and fuel cells are now widely regarded as one of the key energy solutions for the 21st century. These technologies will contribute significantly to a reduction in environmental impact, enhanced energy security (and diversity) and creation of new energy industries. Hydrogen and fuel cells can be utilised in transportation, distributed heat and power generation, and energy storage systems. However, the transition from a carbon-based (fossil fuel) energy system to a hydrogen-based economy involves significant scientific, technological and socioeconomic barriers to the implementation of hydrogen and fuel cells as clean energy technologies of the future. This paper aims to capture, in brief, the current status, key scientific and technical challenges and projection of hydrogen and fuel cells within a sustainable energy vision of the future. We offer no comments here on energy policy and strategy. Rather, we identify challenges facing hydrogen and fuel cell technologies that must be overcome before these technologies can make a significant contribution to cleaner and more efficient energy production processes.

    2010-03-01

    Anticipating a doubling in the world's energy use by the year 2050 coupled with an increasing focus on clean energy technologies, there is a national imperative for new energy technologies and improved energy efficiency. The Department of Energy's Office of Basic Energy Sciences (BES) supports fundamental research that provides the foundations for new energy technologies and supports DOE missions in energy, environment, and national security. The research crosses the full spectrum of materials and chemical sciences, as well as aspects of biosciences and geosciences, with a focus on understanding, predicting, and ultimately controlling matter and energy at electronic, atomic, and molecular levels. In addition, BES is the home for national user facilities for x-ray, neutron, nanoscale sciences, and electron beam characterization that serve over 10,000 users annually. To provide a strategic focus for these programs, BES has held a series of ``Basic Research Needs'' workshops on a number of energy topics over the past 6 years. These workshops have defined a number of research priorities in areas related to renewable, fossil, and nuclear energy -- as well as cross-cutting scientific grand challenges. These directions have helped to define the research for the recently established Energy Frontier Research Centers (EFRCs) and are foundational for the newly announced Energy Innovation Hubs. This overview will review the current BES research portfolio, including the EFRCs and user facilities, will highlight past research that has had an impact on energy technologies, and will discuss future directions as defined through the BES workshops and research opportunities.

    Full text: There is nothing more vital to the advancement of human civilization than the abundance of usable and affordable energy. It underpins national security, economic prosperity, and global stability. Nuclear energy, which exhibits a unique combination of environmental and sustainable attributes, appears strongly positioned to play a much larger and more pivotal role in the mix of future global energy supplies than it has played in the past. Unfortunately, after a fairly rapid growth period within the industrialized nations in the 1960 to 1980 time frame, a variety of factors led to a substantial reduction in commercial nuclear power plant construction (with the possible exception of several Pacific Rim countries). This, in turn, led to a serious erosion in the enrollment patterns of nuclear engineering programs - causing alarmingly low enrollment levels in many counties by the turn of the century. Numerous studies conducted over the past five years have soberly come to the consistent conclusion that the nuclear pipeline cannot keep up with the needs of the nuclear industry. In fact, when combining the aging work force with low matriculation rates in most nuclear engineering academic programs, a huge (and unacceptable) mismatch between needs and supply is strikingly evident. This is further exasperated by the lack of meaningful efforts to capture the knowledge of the 'first nuclear era' professionals in a form that can be effectively transferred to the upcoming generation. Methods must be found to better capture the enormous body of experience already accumulated and both document it and then mentor the new nuclear engineers that do enter the work force to enable them to build upon this experience, rather than having to re-create it. On the positive side, enrollment patterns in the majority of nuclear engineering programs still in existence within the United States are now generally on the rise, at least at the undergraduate level. Some programs have

    The Global Nuclear Vision Project is examining, using scenario building techniques, a range of long-term nuclear energy futures. The exploration and assessment of optimal nuclear fuel-cycle and material strategies is an essential element of the study. To this end, an established global E 3 (energy/economics/environmental) model has been adopted and modified with a simplified, but comprehensive and multi-regional, nuclear energy module. Consistent nuclear energy scenarios are constructed using this multi-regional E 3 model, wherein future demands for nuclear power are projected in price competition with other energy sources under a wide range of long-term demographic (population, workforce size and productivity), economic (price-, population-, and income-determined demand for energy services, price- and population-modified GNP, resource depletion, world-market fossil energy prices), policy (taxes, tariffs, sanctions), and top-level technological (energy intensity and end-use efficiency improvements) drivers. Using the framework provided by the global E 3 model, the impacts of both external and internal drivers are investigated. The ability to connect external and internal drivers through this modeling framework allows the study of impacts and tradeoffs between fossil- versus nuclear-fuel burning, that includes interactions between cost, environmental, proliferation, resource, and policy issues

The ability to connect external and internal drivers through this modeling framework allows the study of impacts and tradeoffs between fossil- versus nuclear-fuel burning, that includes interactions between cost, environmental, proliferation, resource, and policy issues.

  6. The future energy situation in the Netherlands

    International Nuclear Information System (INIS)

    1980-01-01

    This book is the result of a study into the future energy situation in the Netherlands, performed by the electricity companies in the country. The first five chapters sketch the framework within which energy policy is currently forced to operate. Further technical and physical conditions are considered in the following six chapters, including environmental and safety aspects. A prognosis for energy demand in the Netherlands until the end of the century is presented and five different scenarios are discussed, as means of supplying this demand. Nuclear energy is one of the sources considered throughout the text. (C.F.)

    The talk will review some of the basic facts about the history and present status of the use of energy and its climatic consequences. It is clear that the world will have to change its way of energy production, the sooner the better. Because of the difficulty of storing electric energy, by far the best energy source for the future is thermal solar from the deserts, with overnight thermal storage. I will give some description of the present status of the technologies involved and end up with a pilot project for Europe and North Africa.

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

  9. Second Strategic Energy Review. Securing our Energy Future

    International Nuclear Information System (INIS)

    2008-11-01

    Europe has agreed a forward-looking political agenda to achieve its core energy objectives of sustainability, competitiveness and security of supply. This agenda means substantial change in Europe's energy system over the next years, with public authorities, energy regulators, infrastructure operators, the energy industry and citizens all actively involved. It means choices and investments during a time of much change in global energy markets and international relations. The European Commission has therefore proposed a wide-ranging energy package which gives a new boost to energy security in Europe, i.e. putting forward a new strategy to build up energy solidarity among Member States and a new policy on energy networks to stimulate investment in more efficient, low-carbon energy networks; proposing a Energy Security and Solidarity Action Plan to secure sustainable energy supplies in the EU and looking at the challenges that Europe will face between 2020 and 2050; adopting a package of energy efficiency proposals aims to make energy savings in key areas, such as reinforcing energy efficiency legislation on buildings and energy-using products.

    Nuclear energy contributes 17% to global electricity production and almost 40% to the public supply in Germany. Operators of nuclear power plants are having to invest considerable effort in trying to set the public thinking and boring public opinion away from an emotional rejection towards a rational consideration of the risks of different energy systems. It is argued that in view of the specific problems of environmental pollution through CO 2 it should be possible to bring about public acceptance of nuclear energy utilization. (DG) [de

    Paper is trying to clearly present the facts about World nuclear energy production in the past and in the future. The production has increased in last ten years for about 26% and will continue to grow. After next ten years we can expect between 12,5% and 25% higher production than this year. Therefore we, nuclear professionals, should not be pessimistic. We should strive not to use negative words in our communications between ourselves and especially to general public. Instead, we should proudly underline our achievements in the past and prospects for the future stressing all the benefits of this type of energy production.(author)

    Since the Fukushima accident, energy policies have been revisited in many nuclearized countries. The energy debate is complex and must encompass several levels of reflection: an international level marked by the energy/climate equation, and by energy resources economy and geopolitics; a European level because we have made the commitment to build a common electricity and gas energy market; a national level where some strategic priorities can be put forward by governments and populations; a local level where energy-related experiments are more and more frequent. Thus, energy choices cannot be made within the single national and governmental frame any longer. At the international scale, it has become urgent to develop low-carbon energy systems. In the framework of the inevitable implementation of a responsible energy policy, the authors examine the main qualities that energy industries should develop: a safe, real-price and environmentally-friendly energy. These qualities must fit with a European framework capable to use complementarities in a perspective of competitiveness, environmental liability and short-, medium- and long-term security of supplies. All new opportunities for companies, in France and abroad, will develop in this framework as well. The energy future question has become essential and must be dealt beyond the national frame and in close relation with the climate question

    According to a recent study, global wind generating capacity increased by some 6800 MW in 2001, an annual growth of just over half the corresponding figure for 2000. 2001 was the third consecutive year in which new wind power capacity exceeded new nuclear power capacity, showing the maturity of wind power technology. Total installed wind power worldwide by the end of 2001 was close to 25.000 MW. Germany, Spain and Denmark are the main players, accounting for 56% of the world's capacity increase in 2001 and a total cumulative installed capacity of 14.750 MW, or 59% of the global total. The USA and India are also significant users of wind power; in 2001 the USA added 1700 MW of new installed capacity to become the world's second-largest market for wind power. The report Wind Force 10 outlines a scenario in which wind power provides 10% of the world's electricity by 2020, corresponding to a total installed capacity of 1200 GW. Risoe's System Analysis Department has looked at the possible future costs of electricity produced by wind turbines compared to conventional power. A learning curve analysis of historical data results in a progress ratio of 0,85. This means that for every doubling of the installed capacity, the cost of wind-generated electricity is reduced by 15%. Until recently the main driver for wind power has been a concern for greenhouse gases. Security of energy supply has now become an important issue, however, especially in Europe and the USA. Wind power plants can be erected at short notice and in a modular fashion that allows capacity to be added as required. The European Commission has supported wind power by sponsoring international research co-operation between institutes, universities and equipment manufacturers.

    2012-01-01

    The need for alternative sources of energy has never been more urgent than it is today. At the very time International Energy Agency estimates that demand will increase 30% by 2030, fossil fuels (oil, gas and coal) are beginning to dwindle, as the need to counter global warming imposes limits on CO 2 emissions. In this context, DCNS has entered a new field of innovation and development: ocean energy. Having included marine renewable energy as an intrinsic part of its strategic growth plan, DCNS is the only industrial company in the world to invest in all four key technologies in this sector: - the tidal energy generated using underwater turbines known as 'tidal turbines',' which convert the energy of marine tidal streams into electricity; - the ocean thermal energy conversion (OTEC) technology that exploits the difference of temperature between the warm surface water of tropical oceans and the cold water found in the ocean depths to generate electrical power 24 hours a day, 35 days a year; - the offshore wind energy generated by offshore floating wind turbines; - the wave energy technology which operates on the principle of recovering energy from the ocean swell. With 400 years of expertise in shipbuilding and its in-depth understanding of the marine environment, DCNS is committed to playing a major role in the development of this new ocean industry.

[Detrended fluctuation analysis of the US stock market, Int. J. Bifurcation Chaos, forthcoming, 2007] by re-examining the empirical evidence for random walk type behavior in energy futures prices. In doing so, it uses daily data on energy futures traded on the New York Mercantile Exchange, over the period from July 2, 1990 to November 1, 2006, and a statistical physics approach-the ‘detrending moving average’ technique-providing a reliable framework for testing the information efficiency in financial markets as shown by Alessio et al. [Second-order moving average and scaling of stochastic time series, Eur. Phys. J. B 27 (2002) 197-200] and Carbone et al. [Time-dependent hurst exponent in financial time series.

The results show that energy futures returns display long memory and that the particular form of long memory is anti-persistence.

    2010-01-01

    Nuclear energy is back on the agenda worldwide. In order to prepare for the next decades and to set priorities in nuclear R and D and investment, market share scenarios are evaluated. This allows to identify the triggers which influence the market penetration of future nuclear reactor technologies. To this purpose, scenarios for a future nuclear reactor park in Europe have been analysed applying an integrated dynamic process modelling technique. Various market share scenarios for nuclear energy are derived including sub-variants with regard to the intra-nuclear options taken, e.g. introduction date of Gen-III (i.e. EPR) and Gen-IV (i.e. SCWR, HTR, FR) reactors, level of reprocessing, and so forth. The assessment was undertaken using the DANESS code which allows to provide a complete picture of mass-flow and economics of the various nuclear energy system scenarios. The analyses show that the future European nuclear park will exist of combinations of Gen-III and Gen-IV reactors. This mix will always consist of a set of reactor types each having its specific strengths. Furthermore, the analyses highlight the triggers influencing the choice between different nuclear energy deployment scenarios. In addition, a dynamic assessment is made with regard to manpower requirements for the construction of a future nuclear fleet in the different scenarios. (authors)

    High energy particle colliders have been in the forefront of particle physics for more than three decades. At present the near term US, European and international strategies of the particle physics community are centered on full exploitation of the physics potential of the Large Hadron Collider (LHC) through its high-luminosity upgrade (HL-LHC). A number of the next generation collider facilities have been proposed and are currently under consideration for the medium and far-future of accelerator-based high energy physics. In this paper we offer a uniform approach to evaluation of various accelerators based on the feasibility of their energy reach, performance potential and cost range.

    The inefficient use, associated with pollutants, of the fossil energy carriers coal, crude oil and natural gas, will deplete resources, if the energy demand increases exponentially, in the not-too-distant future. That is the reason why the hydrogen-energy concept gains in importance. This requires drastic changes in structure in a lot of technological fields. This task is only to be mastered if there is cooperation between all special fields, in order to facilitate the economical production, distribution and utilization of hydrogen. (orig.) [de

    In this work we will try to show that nuclear energy can contribute to the generation energy in the present and the future, considering that its effect on the climatic change is relatively low and that the fuels that uses are available a large scale. At the moment it is had already commercial thermal fission reactors , there are also them of fast fission that allow the fuel rearing, although these last ones in much smaller number, with both types of fission nuclear reactors can be obtained a very important contribution to the generation of energy at world-wide level during the time that is necessary so that it is developed, constructs and operates the first commercial fusion reactor. The energy that is generated in the present and future must come from different sources, which require to be reliable, to have little effect on the environment, to have wide reserves of fuels and to be viable from an economic and social point of view, they must be viable and safe. Between possible alternative energies it is counted on the lot, the wind one, the geothermal one, originating of the tides and some others. An energy that must be considered so that it has arrived at his maturity and he is already able to contribute widely to cover the present needs and future it is nuclear energy, as much the originating one of the fission of a heavy centre like obtained when fusing two light centers. On base in the nuclear fuel reserves at world-wide level a simple calculation takes control of the lapse in which energy by means of the nuclear fission in rearing can be generated reactors expresses demonstrating that the time sufficient to finish to the investigation and development of fusion reactors which they generate energy in economic, safe and reliable form. Combining these two options the nuclear energy can be considered the future like for the present and the future with practically null effects in the climatic change. (Author)

    The transition to a global low-carbon energy sector is on the agenda of policymakers in the Netherlands, Europe and world-wide. However, the way in which the international political discussion takes place makes it far from clear that such a transition will indeed take place. Conflicts of interest between climate concerns, energy security, access to energy and profits made from fossil fuels should be analysed more properly and taken into account in international energy and climate negotiations in order to prevent that an energy crisis will be the only way forward towards a low-carbon energy sector.

Although some significant cost reductions have been achieved, particularly in PV technology, solar conversion technologies are still not generally competitive against conventional fuels, and future cost reductions may be limited. It is argued that fiscal measures will be necessary if solar conversion technologies are to make a significant global impact. (Author)

    The year 2015 was a significant anniversary for global health: 15 years since the adoption of the Millennium Development Goals and the creation of the Global Alliance for Vaccines and Immunization, followed two years later by the Global Fund to Fight AIDS, TB and Malaria. 2015 was also the 10-year anniversary of the adoption of the International Health Regulations (May 2005) and the formal entering into force of the Framework Convention on the Tobacco Control (February 2005). The anniversary of these frameworks and institutions illustrates the growth and contribution of 'global' health diplomacy. Each initiative has also revealed on-going issues with compliance, sustainable funding and equitable attention in global health governance. In this paper, we present four thematic challenges that will continue to challenge prioritisation within global health governance into the future unless addressed: framing and prioritising within global health governance; identifying stakeholders of the global health community; understanding the relationship between health and behaviour; and the role of governance and regulation in supporting global health.

    For legacy and emerging persistent organic pollutants (POPs), surprisingly little is still known in quantitative terms about their global sources and emissions. Atmospheric transport has been identified as the key global dispersal mechanism for most legacy POPs. In contrast, transport by ocean currents may prove to be the main transport route for many polar, emerging POPs. This is linked to the POPs' intrinsic physico-chemical properties, as exemplified by the different fate of hexachlorocyclohexanes in the Arctic. Similarly, our current understanding of POPs' global transport and fate remains sketchy. The importance of organic carbon and global temperature differences have been accepted as key drivers of POPs' global distribution. However, future research will need to understand the various biogeochemical and geophysical cycles under anthropogenic pressures to be able to understand and predict the global fate of POPs accurately. - Future studies into the global fate of POPs will need to pay more attention to the various biogeochemical and anthropogenic cycles to better understand emissions, transport and sinks

    Wind power in China registered a record level of expansion recently, and has doubled its total capacity every year since 2004. Many experts believe that China will be central to the future of the global wind energy market. Consequently, the growth pattern of wind power in China may be crucial to the further development of the global wind market. This paper firstly presented an overview of wind energy potential in China and reviewed the national wind power development course in detail. Based on the installed wind capacity in China over the past 18 years and the technical potential of wind energy resources, the growth pattern was modeled in this study for the purpose of prospect analysis, in order to obtain projections concerning the development potential. The future perspectives of wind energy development in China are predicted and analyzed. This study provides a comprehensive overview of the current status of wind power in China and some insights into the prospects of China's wind power market, which is emerging as a new superpower in the global wind industry.

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

    2003-01-01

    Debates about whether or not to invest heavily in nuclear fusion as a future innovative energy option have been made within the context of energy technology development strategies. This is because the prospects for nuclear fusion are quite uncertain and the investments therefore carry the risk of quite large regrets, even though investment is needed in order to develop the technology. The timeframe by which nuclear fusion could become competitive in the energy market has not been adequately studied, nor has roles of the nuclear fusion in energy systems and the environment. The present study has two objectives. One is to reveal the conditions under which nuclear fusion could be introduced economically (hereafter, we refer to such introductory conditions as breakeven prices) in future energy systems. The other objective is to evaluate the future roles of nuclear fusion in energy systems and in the environment. Here we identify three roles that nuclear fusion will take on when breakeven prices are achieved: (i) a portion of the electricity market in 2100, (ii) reduction of annual global total energy systems cost, and (iii) mitigation of carbon tax (shadow price of carbon) under CO 2 constraints. Future uncertainties are key issues in evaluating nuclear fusion. Here we treated the following uncertainties: energy demand scenarios, introduction timeframe for nuclear fusion, capacity projections of nuclear fusion, CO 2 target in 2100, capacity utilization ratio of options in energy/environment technologies, and utility discount rates. From our investigations, we conclude that the presently designed nuclear fusion reactors may be ready for economical introduction into energy systems beginning around 2050-2060, and we can confirm that the favorable introduction of the reactors would reduce both the annual energy systems cost and the carbon tax (the shadow price of carbon) under a CO 2 concentration constraint

    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.

Several results of the long-term energy demand and supply analysis in 2050 or 2100 to reduce drastically carbon dioxide emission as a measure against global warming, showed the necessity of nuclear power deployment as well as maximum efforts to save energy, exploitation of the separation and disposal of carbon dioxide, and shifting energy sources to fuels that emit less greenhouse gases or non-fossil fuels. As a promising means to contribute to long-term energy supply, nuclear power generation is expected with improving safety, economic efficiency, environmental adaptability, and nuclear proliferation resistance of the technologies.

    2012-06-01

    The years 2012 and beyond seem likely to record major changes in energy use and power generation. The Japanese tsunami has resulted in large countries either scaling back or abolishing the future use of nuclear energy. The discovery of what seems like vast amounts of economically deliverable natural gas has many forecasting a rapid switch from coal- to gas-fired generating plants. On the other hand, environmentalists have strong objections to the production of natural gas and of petroleum by hydraulic fracturing from shale, or by extraction of heavy oil. They believe that global warming from the use of fossil fuels is now established beyond question. There has been rapid progress in the development of alternative energy supplies, particularly from on-shore and off-shore wind. Progress toward a viable future energy mix has been slowed by a U.S. energy policy that seems to many to be driven by politics. The author will review the history of power and energy to put all of the above in context and will look at possible future developments. He will propose what he believes to be an idealized energy policy that could result in an optimum system that would be arrived at democratically.

    Fossil fuels provide about 80% of the global energy demand, and this will continue to be the situation for decades to come. In the European Community we are facing two major energy challenges. The first is sustainability, and the second is security of supply, since Europe is becoming more dependent on imported fuels. These challenges are the starting point for the present Risoe Energy Report 6. It gives an overview of the energy scene together with trends and emerging energy technologies. The report presents status and trends for energy technologies seen from a Danish and European perspective from three points of view: security of supply, climate change and industrial perspectives. The report addresses energy supply technologies, efficiency improvements and transport. The report is volume 6 in a series of reports covering energy issues at global, regional and national levels. The individual chapters of the report have been written by staff members from the Technical University of Denmark and Risoe National Laboratory together with leading Danish and international experts. The report is based on the latest research results from Risoe National Laboratory, Technical University of Denmark, together with available internationally recognized scientific material, and is fully referenced and refereed by renowned experts. Information on current developments is taken from the most up-to-date and authoritative sources available. Our target groups are colleagues, collaborating partners, customers, funding organizations, the Danish government and international organizations including the European Union, the International Energy Agency and the United Nations.

    At a global level, primary energy resources are amply sufficient to meet the growing needs expected over the coming decades. Energy supplies may however be affected by economic, technological or political conditions. Supplies of oil and natural gas will be dependent in particular on the carrying out of the necessary investments in the field of development, production capacity, transport and distribution within a suitable time. The future for coal is above all linked to future environmental policies to be put in place and on the capacity of 'clean' coal technologies to respond to these. Due to their costs, which remain high, and to a lack of incentive policies, renewable energy sources should find it difficult to gain a major share of world energy markets. Finally, the future for nuclear energy remains dependent upon policies concerning security of supply or the fight against climatic change. (author)

    2002-01-01

    This article is the work of a group of students from the ''Ecole Nationale d'Administration'', they had to study the perspective of nuclear energy in France. Nuclear energy is an important element to assure the stability of the energy supply of the country. Uranium purchases appear to be safe for being diversified and the price of the nuclear fuel contributes to only 20% of the price of the kWh compared to 40% for natural gas. Today the competitiveness of nuclear energy is assured but technological progress concerning gas turbines might challenge it in the years to come. Sustainable development implies not only abundant energy for all but also a preserved environment for the generations to come. The development of nuclear energy is hampered by the lack of satisfactory answers to the problem of fuel back-end cycle and more generally to the issue of radioactive wastes. On the other hand nuclear energy presents serious assets concerning the preservation of environment: nuclear energy as a whole from the uranium ore mining to the production of electricity emits very few atmospheric pollutants and greenhouse effect gases, and requires little room for its installations. The composition of the future energy mix will depend greatly on opinions and assumptions made about the reserves of fossil fuels, technological perspectives and the perception by the public of industrial risks (environmental damage, nuclear accidents...).

  20. Coal and nuclear power: Illinois' energy future

    International Nuclear Information System (INIS)

    1982-01-01

    This conference was sponsored by the Energy Resources Center, University of Illinois at Chicago; the US Department of Energy; the Illinois Energy Resources Commission; and the Illinois Department of Energy and Natural Resources. The theme for the conference, Coal and Nuclear Power: Illinois' Energy Future, was based on two major observations: (1) Illinois has the largest reserves of bituminous coal of any state and is surpassed in total reserves only by North Dakota, and Montana; and (2) Illinois has made a heavy commitment to the use of nuclear power as a source of electrical power generation. Currently, nuclear power represents 30% of the electrical energy produced in the State. The primary objective of the 1982 conference was to review these two energy sources in view of the current energy policy of the Reagan Administration, and to examine the impact these policies have on the Midwest energy scene. The conference dealt with issues unique to Illinois as well as those facing the entire nation. A separate abstract was prepared for each of the 30 individual presentations

    Future directions in government energy policies are assessed in light of the energy evolution following the 1973 oil crisis and the impacts created by technology transfer and other factors. In particular, the paper examines changes which are occurring in global marketing and commercialization trends, and in public opinion, especially in response to the techniques employed by planners in assessing new energy sources and technologies designed to lessen dependency on oil imports. It is noted that greater consideration must be given by scientists and engineers to the socio-economic impacts of their research efforts.

    2009-01-01

    This article aims to assess the likely competitiveness of different forms of renewable energy in Colombia over the next 25 years. To this end, it compares the likely power production cost for a set of renewable energy sources, and compares them to the likely long-run cost of traditional energy. Costs from global and local externalities through the use of traditional energy sources are also factored into the analysis. The key conclusion of the article is that while solar PV will likely remain uncompetitive under any future cost scenario, cost paths for small hydro, modern biomass or geothermal are already close enough to being competitive, so that appropriate government intervention may make the decisive difference in making these technologies competitive with conventional energy technologies.

    2017-06-07

    Future energy systems will be determined by the increasing relevance of solar and wind energy. Crude oil and gas prices are expected to increase in the long run, and penalties for CO 2 emissions will become a relevant economic factor. Solar- and wind-powered electricity will become significantly cheaper, such that hydrogen produced from electrolysis will be competitively priced against hydrogen manufactured from natural gas. However, to handle the unsteadiness of system input from fluctuating energy sources, energy storage technologies that cover the full scale of power (in megawatts) and energy storage amounts (in megawatt hours) are required. Hydrogen, in particular, is a promising secondary energy vector for storing, transporting, and distributing large and very large amounts of energy at the gigawatt-hour and terawatt-hour scales. However, we also discuss energy storage at the 120-200-kWh scale, for example, for onboard hydrogen storage in fuel cell vehicles using compressed hydrogen storage. This article focuses on the characteristics and development potential of hydrogen storage technologies in light of such a changing energy system and its related challenges. Technological factors that influence the dynamics, flexibility, and operating costs of unsteady operation are therefore highlighted in particular. Moreover, the potential for using renewable hydrogen in the mobility sector, industrial production, and the heat market is discussed, as this potential may determine to a significant extent the future economic value of hydrogen storage technology as it applies to other industries. This evaluation elucidates known and well-established options for hydrogen storage and may guide the development and direction of newer, less developed technologies.

    2010-01-01

    With the increasing negative effects of fossil fuel combustion on the environment in addition to limited stock of fossil fuel have forced many countries to inquire into and change to environmentally friendly alternatives that are renewable to sustain the increasing energy demand. Energy policy plays a vital role to mitigate the impacts of global warming and crisis of energy availability. This paper explores the wind energy industry from the point of view of the wind energy policy. It is noticed that energy policy could help increasing wind power generation as well as stimulating the energy industry. It may be stated that without specific energy policy, a country would not be able to solve the acute problems like reducing greenhouse gases (GHGs) emission, scarcity of energy, etc. This paper discussed the existing successful energy policies for few selected countries. Based on literatures, it has been found that FIT, RPS, incentives, pricing law and Quota system are the most useful energy policies practiced by many countries around the world. Then, status of wind energy policy for Malaysia was investigated and compared with few selected countries around the world. (author)

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

    Global climate change is anticipated to cause some major changes in hydroclimatic conditions around the world. As aridity is a reliable indicator of potential available water, assessment of its changes under future climatic conditions is important for proper management of water. This study employs the UNESCO aridity/humidity index, which is a derivative of precipitation (P) and potential evapotranspiration (PET), for assessment of aridity. Historical (1901-2005) simulations and future (2006-2100) projections of 22 global climate models (GCMs) from the fifth phase of the Coupled Model Intercomparison Project (CMIP5) are studied. The Nested Bias Correction (NBC) approach is used to correct possible biases of precipitation (simulated directly by the GCMs) and PET (estimated by applying FAO56-Penman-Monteith model on simulated parameters of the GCMs). To detect future aridity changes, the areal extents of the aridity zones in the past and future periods as well as through four sub-periods (2006-2025, 2026-2050, 2051-2075, and 2076-2100) of the future are compared. The results indicate that changes in climate will alter the areal extents of aridity zones in the future. In general, from the first sub-period towards the last one, the area covered by hyper-arid, arid, semi-arid, and sub-humid zones will increase (by 7.46%, 7.01%, 5.80%, and 2.78%, respectively), while the area of the humid regions will decrease (by 4.76%), suggesting that there will be less water over the global land area in the future. To understand the cause of these changes, precipitation and PET are also separately assumed to be stationary throughout the four future sub-periods and the resulting aridity changes are then analyzed. The results reveal that the aridity changes are mostly caused by the positive PET trends, even though the slight precipitation increase lessens the magnitude of the changes.

    2008-07-01

    In the framework of the project 'Vision of Future Networks', models and methods have been developed that enable a greenfield approach for energy systems with multiple energy carriers. Applying a greenfield approach means that no existing infrastructure is taken into account when designing the energy system, i.e. the system is virtually put up on a green field. The developed models refer to the impacts of energy storage on power systems with stochastic generation, to the integrated modelling and optimization of multi-carrier energy systems, to reliability considerations of future energy systems as well as to possibilities of combined transmission of multiple energy carriers. Key concepts, which have been developed in the framework of this project, are the Energy Hub (for the conversion and storage of energy) and the Energy Interconnector (for energy transmission). By means of these concepts, it is possible to design structures for future energy systems being able to cope with the growing requirements regarding energy supply. (author)

  14. Energy supply today and tomorrow, national and global

    International Nuclear Information System (INIS)

    Ott, G.

    2003-01-01

    A status report about 'Energy Supply Today and Tomorrow, National and Global' focuses mainly on global aspects. Today's world energy consumption is dominated by more than 80% of fossil sources of energy followed by so-called non-commercial energies, such as wood and plant and animal wastes, contributing 10%; nuclear power, 7%; and hydroelectric power, 2%. The development of energy consumption until the middle of this century will continue to be driven by the further growth of the world population, and by the need to meet the rising demand for energy in the developing countries. Because of their availability and flexible uses, oil, natural gas, and coal as fossil sources of energy will continue to meet a considerable share of the requirement. The use of nuclear power, a source meeting all criteria, such as safety, waste management, and competitiveness, is both justifiable and desirable. Restrictive decisions about nuclear power taken today must not impair the freedom of choice of future generations. Using renewable energies is just as desirable as increasing energy efficiency; however, the technical and physical potentials available for this purpose should not be overrated. This makes it imperative to protect the supply of energy 'in this difficult interim phase' with all the options available, and to open up prospects for the future, also by conducting the appropriate energy and environmental research. The balance between continuity of supply, environmental compatibility, and competitiveness must be taken into account in this effort. In the second half of the 21 st century, it is possible that energy consumption will stabilize when the world's population ceases to grow. New technologies, some of which may not even be known today or may still be under development, could then pave the way for an energy supply system which, in toto, would be less of a burden on the environment.

    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

    Society will not be able to afford nonfossil fuel energy in the future without a major restructuring of industrial activity, involving a complete rethinking of the basis of our present social and economic establishment. This restructuring must be combined with the evident necessity of policies of population restriction and controls in the form of international allocation of the dwindling supply of raw materials, including fossil (and, in future, nonfossil) primary energy. Only by such means, and by adopting a very low-growth future, can some moderate degree of standard of living be expected to be perpetuated for at least a few generations in the industrialized countries, especially in the case of those that are major energy importers at present. This type of future will also be of more help to the third world than one involving the now impossible ideal of a spiraling energy growth rate. The society which, on an optimistic view, will emerge toward the end of the fossil fuel era, will be supplied with abundant, though efficiently applied, energy, and will survive with natural products and by economizing its recylced mineral resources. The approach to this goal will require political leadership, serious education of the public, and a real population policy, all on a world-wide scale. (Conclusions)

  19. Eduction and outreach for the global energy challenge

    Snieder, R.

    2008-12-01

    Energy is the life-blood of the modern world. According to the Energy Information Administration, global energy consumption is expected to grow by about 70% in the coming 25 years. Much of this growth is driven by developing countries, whose inhabitants seek a standard of living that more closely resembles that of the western world. Petroleum provides about 40% of the world-wide energy demand, and, although estimates vary, oil production is expected to peak in the relatively near-future. The combination of increased energy demand and declining petroleum supply can be a threat to political stability and is likely to lead to a shift towards coal and non-conventional oil. This will further increase CO2 emissions and thus accelerate global warming and life-altering regional climate changes. Many actions can be taken now to begin to reduce energy demand, diversify our energy portfolio, and reduce costs of energy supplies, with lower greenhouse gas emissions. This will not happen, however, without a plan and the willingness to implement such a plan. Public engagement and education in dealing with the pressing challenges and opportunities are the key to getting started now. In order to foster such engagement I have prepared the presentation "The Global Energy Challenge." This Powerpoint presentation is freely available and aims to be appealing and understandable for a broad audience. The comment-boxes in the Powerpoint presentation give ideas for a narrative. The presentation sketches the tension between increased energy demand, peak oil, the associated challenge in curbing climate change, and actions that we can take towards a sustainable energy system. The presentation gives ideas for positive action that teachers, students, businessmen, consumers, and citizens can take, and it conveys that the challenges related to our energy supply come with career opportunities, a point that is especially appealing to a young audience.

    2010-01-01

    The following article will analyse the global and geopolitical dimensions of the future international energy security and its implications for Europe and the EU-27. In this context, I will discuss to which extent the EU's newly proclaimed 'Energy Action Plan' of the EU Spring summit of 2007 and its declared common energy (foreign) policy are a sufficient strategy to cope with the new global and geopolitical challenges. The article concludes the following: (1) The interlinkage between globally designed traditional energy security concepts - that rely just on economic factors and 'market-strategies' - and domestic as well as regional political stability demands new thinking with regard to both energy supply security and foreign and security policies. (2) Although after the Russian-Ukrainian gas conflict in January 2006, energy security has forced its way up the European energy and foreign policy agendas, the EU-27 member states have largely failed to forge a coherent European energy security and energy foreign policy strategy after their Spring summit of 2007 because its declared political solidarity has been still lacking. But the 2nd Strategic Energy Review of November 2008 has recommended new initiatives to overcome this lack by promoting concrete infrastructure and other projects for enhancing Europe's supply security and its political solidarity as part of a common energy (foreign) policy. If the EU is able to implement the March 2007 and November 2008 decisions, the EU oil and gas demand will drastically reduce and freeze at current levels. In this case, Putin's energy policies by using Russia's energy resources and pipeline monopolies as a political instrument to enforce its economic and geopolitical interests will be proved as self-defeating in Russia's long-term strategic interests. It will reduce Gazprom's gas exports to a much smaller EU gas market than originally forecasted as the result of a deliberate EU policy of decreasing its overall gas demand and

  3. Exploring future scenarios for the global supply chain of tuna

    The abundance of tuna, an important top predator that ranges throughout tropical and subtropical oceans, is now largely determined by fishing activity. Fishing activity, in turn, is determined by the interaction of fish availability, fishing capacity, fishing costs and global markets for tuna products. In the face of overfishing, the continued sustainable supply of tuna is likely to require improved global governance, that would benefit from modeling frameworks capable of integrating market forces with the availability of fish in order to consider alternative future projections. Here we describe such a modeling framework, in which we develop several simple, contrasting scenarios for the development of the tuna supply chain in order to illustrate the utility of the approach for global evaluation of management strategies for tuna and other complex, stock-structured fisheries. The model includes multiple national and multi-national fishing fleets, canneries and fresh/frozen markets, and connects these to global consumers using a network of flows. The model is calibrated using recent data on fish catch, cannery and fresh/frozen production, and consumption. Scenarios explore the control on future outcomes in the global tuna fishery by representing, in a simple way, the effects of (1) climate change, (2) changes in the global demand for tuna, and (3) changes in the access to fishing grounds (marine reserves). The results emphasize the potential importance of increasing demand in provoking a global collapse, and suggest that controlling tuna production by limiting technical efficiency is a potential countermeasure. Finally we discuss the outcomes in terms of potential extensions of the scenario approach allowed by this global network model of the tuna supply chain.

    The author states two general ways in which one must proceed in an attempt to forecast the future of high energy physics. The first is to utilize the state of knowledge in the field and thereby provide theoretical and experimental guidance on future directions. The second approach is technical, namely, how well can one do in going to higher energies with present techniques or new accelerator principles. He concludes that the future strategy is straightforward. The present accelerator facilities must be upgraded and run to produce exciting and forefront research. At the same time, the theoretical tools should be sharpened both extrapolating from lower energies (100 GeV) to high (multi TeV) and vice versa. The US should be involved in the LHC, both in the accelerator and experimental areas. There should be an extensive R and D program on accelerators for a multi-TeV capability, emphasizing e + e - and μ + μ - colliders. Finally, the international cooperative activities should be strengthened and maintained

    This paper deals with the future of clean energy in Alberta. With the present economic growth of the oil sands industry in Alberta, it is expected that there will be very considerable increases in job opportunities and GDP in both Canada and US. The challenges include high-energy demand and reduction of the carbon footprint. Alberta has adopted certain approaches to developing renewable and alternate forms of energy as well as to increasing the efficiency of present energy use and raising environmental consciousness in energy production. Three areas where the effects of clean energy will be felt are energy systems, climate change, and regional impacts, for instance on land, water, and wildlife. Alberta's regulatory process is shown by means of a flow chart. Aspects of oil sands environmental management include greenhouse gas targets, air quality assurance, and water quality monitoring, among others. Steps taken by Alberta to monitor and improve air quality and water management are listed. In conclusion, the paper notes that significant amounts of money are being pumped into research and development for greenhouse gas and water management projects.

    Urban expansion often occurs on croplands. However, there is little scientific understanding of how global patterns of future urban expansion will affect the world's cultivated areas. Here, we combine spatially explicit projections of urban expansion with datasets on global croplands and crop yields. Our results show that urban expansion will result in a 1.8-2.4% loss of global croplands by 2030, with substantial regional disparities. About 80% of global cropland loss from urban expansion will take place in Asia and Africa. In both Asia and Africa, much of the cropland that will be lost is more than twice as productive as national averages. Asia will experience the highest absolute loss in cropland, whereas African countries will experience the highest percentage loss of cropland. Globally, the croplands that are likely to be lost were responsible for 3-4% of worldwide crop production in 2000. Urban expansion is expected to take place on cropland that is 1.77 times more productive than the global average. The loss of cropland is likely to be accompanied by other sustainability risks and threatens livelihoods, with diverging characteristics for different megaurban regions. Governance of urban area expansion thus emerges as a key area for securing livelihoods in the agrarian economies of the Global South.

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

    The economic development in the German Democratic Republic within the preceding 10 years has proved that future stable economic growth of about 4 to 4.5% per annum is only achievable by ways including methods of saving resources. This requires due to the close interdependences between the social development and the level of the development in the energy sector long-term growth rates of the national income of 4 to 4.5% per annum at primary energy growth rates of less than 1% per annum. It comprises three main tendencies: 1. Organization of a system with scientific-technical, technological, economic structural-political and educational measures ensuring in the long term less increase of the energy demand while keeping the economic growth at a constant level. 2. The long-term moderate extension and modernization of the GDR's energy basis is characterized by continuing use of the indigenous brown coal resources for the existing power plant capacities and for district heating. 3. The use of modern and safe nuclear power technologies defines a new and in future more and more important element of the energy basis. Currently about 10% of electricity in the GDR are covered by nuclear energy, in 2000 it will be one third, after 2000 the growth process will continue. The experience shows: If conditions of deepened scientific consideration of all technological processes and the use of modern diagnosis and computer technologies as well as permanent improvement of the safety-technological components and equipment are guaranteed an increasing use of such systems for the production of electricity and heat is socially acceptable. Ensuring a high level of education and technical training of everyone employed in the nuclear energy industry, strict safety restrictions and independent governmental control of these restrictions are important preconditions for the further development in this field. 3 refs, 5 tabs

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

  13. Global pyrogeography: the current and future distribution of wildfire.

    Meg A Krawchuk

    Full Text Available Climate change is expected to alter the geographic distribution of wildfire, a complex abiotic process that responds to a variety of spatial and environmental gradients. How future climate change may alter global wildfire activity, however, is still largely unknown. As a first step to quantifying potential change in global wildfire, we present a multivariate quantification of environmental drivers for the observed, current distribution of vegetation fires using statistical models of the relationship between fire activity and resources to burn, climate conditions, human influence, and lightning flash rates at a coarse spatiotemporal resolution (100 km, over one decade. We then demonstrate how these statistical models can be used to project future changes in global fire patterns, highlighting regional hotspots of change in fire probabilities under future climate conditions as simulated by a global climate model. Based on current conditions, our results illustrate how the availability of resources to burn and climate conditions conducive to combustion jointly determine why some parts of the world are fire-prone and others are fire-free. In contrast to any expectation that global warming should necessarily result in more fire, we find that regional increases in fire probabilities may be counter-balanced by decreases at other locations, due to the interplay of temperature and precipitation variables. Despite this net balance, our models predict substantial invasion and retreat of fire across large portions of the globe. These changes could have important effects on terrestrial ecosystems since alteration in fire activity may occur quite rapidly, generating ever more complex environmental challenges for species dispersing and adjusting to new climate conditions. Our findings highlight the potential for widespread impacts of climate change on wildfire, suggesting severely altered fire regimes and the need for more explicit inclusion of fire in research

  15. The Global Surge in Energy Innovation

    2014-08-01

    Full Text Available Policymakers are seeking a transformation of the energy system driven by concerns about climate change, energy security and affordability. At the same time, emerging developments in underpinning science and engineering are opening up new possibilities across the whole technology spectrum covering renewables and other supply side technologies, energy demand and energy infrastructure. This paper reviews both the “policy pull” for energy innovation activities and the “science and technology push”. It explores the expectations of a variety of organisations in both the public and private sector regarding these pressures and possibilities by assessing various scenarios and outlook exercises that have been published since 2013. It reveals a wide range of beliefs about the future development of the energy system. The paper then moves on to analyse private sector expenditure on energy research and development (R&D and public sector budgets for energy R&D and demonstration (RD&D. This analysis demonstrates significant divergences in patterns of innovation between the private and public sectors and leads to the hypothesis that the private sector is, broadly, taking measures to reinforce the existing energy paradigm while the public sector is focusing on new energy technologies that support wider policy objectives. This pattern is consistent with past technological transitions, with innovation efforts that would transform the energy system being counteracted by countervailing efforts that reinforce the existing fossil fuel-based paradigm.

    The explosion of fossil fuel prices is considered as a threat for our industries, for employment and for our economic growth. But why would not it be finally a formidable opportunity to create a new growth, sustainable, respectful to the environment and to future generations? We have been frantically consuming energy for 150 years now, considering that our resources are unexhaustible. However, another way to stimulate growth, consume energy, and manage to combine security of supplies and fight against global warming as well is possible. Energy efficiency techniques, development of renewable energy sources and electric-powered vehicles, CO 2 capture and sequestration are some of the components of this new deal. Accelerated by the present day situation and stimulated by competition, each can contribute to generate growth and employment. The present day crisis leads us to count even more on inventiveness and research and to intelligently change our behaviours without diminishing our comfort. (J.S.)

    An account is first given of the origin of present chemical fuels, with particular reference to the lastingness of coal. Methods of estimation of these fuels are discussed and the greenhouse effect arising from the burning of coal is described. Consideration is then given to methods available for extending the uses of chemical fuels, including interfacing them with new inexhaustible, clean energy sources. Finally, accounts are given of the Hydrogen Economy and of the production of chemical fuels from wind energy in massive wind belts. The paper includes references to the part that nuclear power was expected to play in future energy policy. Problems of breeder reactor development and the safety and management of plutonium and radioactive wastes are discussed. (author)

    The present study describes the migration path that must be taken up to the year 2030 in pursuit of the Future Energy Grid. For this purpose it has explored what possible future scenarios must be taken into account along the migration path. The following key factors were identified in preparation of drawing up scenarios: expansion of the electrical infrastructure; system-wide availability of an information and communication technology infrastructure; flexibilisation of consumption; energy mix; new services and products; final consumer costs; and standardisation and political framework conditions. These eight key factors were combined with each other in different variants to give three consistent scenarios for the year 2030.

  1. The energy future of Central Europe; Slovakia

    International Nuclear Information System (INIS)

    Lejon, E.

    1996-01-01

    In this part of the book author deals with the energy future of Central Europe. The energy strategy, structure of energy supplies in Austria, Slovakia, the Czech Republic, Hungary and Bavaria, as well as restructuralization of the energy sources are analysed. From the ecological perspective, the Gabcikovo-Nagymaros Project (GNP) represents a very clear example, since the Project could play a very important role as a part of the strategy to reject nuclear energy , the same strategy that was clearly declared by the Austrian government, as well as for a transportation strategy based more on railroads and navigation. The GNP could serve as an impulse promoting further and more close Central European cooperation in renewable energy sources. It could assist in harmonization of the interest in the sphere of transportation policies of Switzerland, Bavaria, Austria, Slovakia, and Hungary. Such a community oriented towards common interests would definitely be of enormous importance for the development of transportation in Central Europe. Geothermal potential of Slovakia and other Central European states are presented. Surveys conducted in Slovakia show that it is possible to reduce pollution in specific areas by substituting fossil energy sources with geothermal heating a total reduction of pollution by 39,000 tons annually, out of which 159 tons represent the annual reduction of sulfur dioxide pollution. The reduction per GWh of geothermal heat in the particular cities was calculated to be about 527 tons of carbon dioxide and 2.1 ton of sulfur dioxide. Other opportunities for renewable energy in Slovakia, as well as potential of energy savings are estimated

    The report discusses the perspectives on the evolving U.S. electricity future, the renewable electric technology portfolio, the regional outlook, and the opportunities to move forward. Renewables are at a critical juncture as the domestic electricity marketplace moves toward an era of increased choice and greater diversity. The cost and performance of these technologies have improved dramatically over the past decade, yet their market penetration has stalled as the power industry grapples with the implications of the emerging competitive marketplace. Renewable energy technologies already contribute to the global energy mix and are ready to make an even greater contribution in the future. However, the renewables industry faces critical market uncertainties, both domestically and internationally, as policy commitments to renewables at both the federal and state levels are being reshaped to match the emerging competitive marketplace. The energy decisions that we make, or fail to make, today will have long-lasting implications. We can act now to ensure that renewable energy will play a major role in meeting the challenges of the evolving energy future. We have the power to choose.

  3. Air quality and future energy system planning

    2016-04-01

    Ambient air pollution has been linked to an increasing number of premature deaths throughout the world. Projected increases in demand for food, energy resources and manufactured products will likely contribute to exacerbate air pollution with an increasing impact on human health, agricultural productivity and climate change. Current events such as tampering emissions tests by VW car manufacturers, failure to comply with EU Air Quality directives and WHO guidelines by many EU countries, the problem of smog in Chinese cities and new industrial emissions regulations represent unique challenges but also opportunities for regulators, local authorities and industry. However current models and practices of energy and resource use do not consider ambient air impacts as an integral part of the planing process. Furthermore the analysis of drivers, sources and impacts of air pollution is often fragmented, difficult to understand and lacks effective visualization tools that bring all of these components together. This work aims to develop a model that links impacts of air quality on human health and ecosystems to current and future developments in the energy system, industrial and agricultural activity and patterns of land use. The model will be added to the ForeseerTM tool, which is an integrated resource analysis platform that has been developed at the University of Cambridge initially with funding from BP and more recently through the EPSRC funded Whole Systems Energy Modeling (WholeSEM) project. The basis of the tool is a set of linked physical models for energy, water and land, including the technologies that are used to transform these resources into final services such as housing, food, transport and household goods. The new air quality model will explore different feedback effects between energy, land and atmospheric systems with the overarching goal of supporting better communication about the drivers of air quality and to incorporate concerns about air quality into

    2005-07-01

    Global primary energy demand is expected to increase by 1.7 per cent annually from 2000 to 2030, reaching an annual level of 15.3 billion tonnes of oil equivalent. Fossil fuels are expected to supply over 90 per cent of global incremental energy demand through 2030, while gas consumption is estimated to double between 2000 and 2030 due to its cost competitiveness, high availability and environmental advantages. Oil will remain the largest fuel source with demand increasing by 1.6 per cent annually. In order to tap the vast Canadian resource potential, innovative new technologies are needed to unlock the remaining conventional oil and gas reserves. It was argued that no single source of energy will be sufficient to meet world or Canadian demand. Therefore, there is also a need for a collaborative initiative to facilitate a long-term effort to implement an integrated energy innovation strategy. The Energy Innovation Network (EnergyINet) was created help industry, governments, and the research community address the challenges of ensuring an abundant supply of environmentally responsible energy. Given the right technologies, bitumen, coal, and coalbed methane have hundreds of years of production remaining. Production of those reserves depends on finding effective solutions to production costs, cost and availability of feedstocks needed to produce higher valued products, market limitations, and land, water, air, and greenhouse gas issues. The main challenge is to finance the development of such technologies into reliable, large-scale commercial applications. It was concluded that Canada's ability to maintain competitive energy supplies from conventional and non-conventional energy systems will be severely limited as the need to protect the environment, reduce greenhouse gas emissions, and conserve water moves higher on the public agenda. 13 refs.

  5. Transmutation and the Global Nuclear Energy Partnership

    International Nuclear Information System (INIS)

    Bresee, James

    2007-01-01

    In the January 2006 State of the Union address, President Bush announced a new Advanced Energy Initiative, a significant part of which is the Global Nuclear Energy Initiative. Its details were described on February 6, 2006 by the U.S. Secretary of Energy. In summary, it has three parts: (1) a program to expand nuclear energy use domestically and in foreign countries to support economic growth while reducing the release of greenhouse gases such as carbon dioxide. (2) an expansion of the U.S. nuclear infrastructure that will lead to the recycling of spent fuel and a closed fuel cycle and, through transmutation, a reduction in the quantity and radiotoxicity of nuclear waste and its proliferation concerns, and (3) a partnership with other fuel cycle nations to support nuclear power in additional nations by providing small nuclear power plants and leased fuel with the provision that the resulting spent fuel would be returned by the lessee to the lessor. The final part would have the effect of stabilizing the number of fuel cycle countries with attendant non-proliferation value. Details will be given later in the paper. Commercial spent fuel recycling, pioneered in the U.S., has not been carried out since the nineteen seventies following a decision by President Carter to forego fuel reprocessing and to recommend similar practices by other countries. However, many nations have continued spent fuel reprocessing, generally using the U.S.-developed PUREX process. The latest to do so are Japan, which began operations of an 800 metric tons (tonnes) per year PUREX reprocessing plant at Rokkasho-mura in northern Honshu in 2006 and China, which recently began operations of a separations pilot plant, also using PUREX. Countries using the PUREX process, recycle the separated plutonium to light water reactors (LWRs) in a mixed plutonium/uranium oxide fuel called MOX. Plutonium recycling in LWRs, which are used for electricity production in all nuclear power nations, reduces

    2002-01-01

    The paper presents an analysis of the future of nuclear energy at the European level taking into account the main factors which influence its development among which the most important are: - enlargement of EU to 30 member states with different energy structure; - the increase of energy consumption; - the constant increasing of external dependence for energy which is estimated at 70% in the next 20-30 years; - liberalisation of the energy sources and supply sector; - environmental concerns, including climate change. In the Green Paper, nuclear is grouped together with coal, oil, gas and renewables as 'less than perfect' energy options and together with coal it is classed as an 'undesirable' and referred to as a 'source of energy in doubt ' which is ' tainted by the original sin of dual usage (civil and military) in the fuel cycle'. The final conclusion is 'the future of nuclear energy in Europe is uncertain'. It depends on several factors beyond energy demand; including: a solution to the problems of managing nuclear waste, the economic viability of the new generation of power stations, the safety of reactors in Eastern Europe, in particular applicant countries and policies to combat global warming. The 'essential questions' for nuclear is 'How can the community develop fusion technology and reactors for the future, reinforce nuclear safety and find a solution to the problem of nuclear waste?' There are a number of very important factors that will influence the future of nuclear energy inside the European Union. The first and foremost of these is continuing the safe operation of the existing nuclear facilities. The second is the demand for energy, in particular electricity. The third is the nuclear sector's ability to meet a share of this demand in a competitive way. If the demand materialises, there are likely to be reactors available that can further improve nuclear competitiveness while maintaining its recent excellent safety record. It will be the market that

    Full Text Available We chose this theme to highlight the need for continuous and sustained human society to secure energy resources needed to survive, needs reflected in an increasingly in recent years in the strategies adopted at both states, as at the level of international organizations. Achieving security and stability in the wider Black Sea area has been among the priorities of each country's interests in this region. In this context, state and non-state actors were being called to come up with new solutions to achieve those interests. Certainly not in all cases the negotiations were completed or not yet found a generally accepted formula for others to apply, but most of them show off their values. The main environmental threats to security environment in the Black Sea region are represented by ethnic conflicts and territorial secessionism. A significant contribution to the security environment of the Black Sea region has the phenomenon of globalization, which in this region is manifested by a steady increase in traffic and volume of shipping passage of communication, which largely affects the security in the region. Globalization and the need for energy resources in the Black Sea was an important area not only as energy transport route, but as a potential supplier of material energy (oil and natural gas. Black Sea Basin can be stabilized and secured only by the will and input from all States and interested international organizations in pragmatic and effective institutional frameworks, meant to promote and protect the common interests of countries decided to participate in actions aimed at ensuring a stable environment security.

    Recently two of the authors proposed a mechanism of vacuum energy sequester as a means of protecting the observable cosmological constant from quantum radiative corrections. The original proposal was based on using global Lagrange multipliers, but later a local formulation was provided. Subsequently other interesting claims of a different non-local approach to the cosmological constant problem were made, based again on global Lagrange multipliers. We examine some of these proposals and find their mutual relationship. We explain that the proposals which do not treat the cosmological constant counterterm as a dynamical variable require fine tunings to have acceptable solutions. Furthermore, the counterterm often needs to be retuned at every order in the loop expansion to cancel the radiative corrections to the cosmological constant, just like in standard GR. These observations are an important reminder of just how the proposal of vacuum energy sequester avoids such problems.

    This paper summarizes an assessment of future energy-technology strategies for China that explored the prospects for China to continue its social and economic development while ensuring national energy-supply security and promoting environmental sustainability over the next 50 years. The MARKAL energy-system modeling tool was used to build a model of China's energy system representing all sectors of the economy and including both energy conversion and end-use technologies. Different scenarios for the evolution of the energy system from 1995 to 2050 were explored, enabling insights to be gained into different energy development choices. The analysis indicates a business-as-usual strategy that relies on coal combustion technologies would not be able to meet all environmental and energy security goals. However, an advanced technology strategy emphasizing (1) coal gasification technologies co-producing electricity and clean liquid and gaseous energy carriers (polygeneration), with below-ground storage of some captured CO 2 ; (2) expanded use of renewable energy sources (especially wind and modern biomass); and (3) end-use efficiency would enable China to continue social and economic development through at least the next 50 years while ensuring security of energy supply and improved local and global environmental quality. Surprisingly, even when significant limitations on carbon emissions were stipulated, the model calculated that an advanced energy technology strategy using our technology-cost assumptions would not incur a higher cumulative (1995-2050) total discounted energy system cost than the business-as-usual strategy. To realize such an advanced technology strategy, China will need policies and programs that encourage the development, demonstration and commercialization of advanced clean energy conversion technologies and that support aggressive end-use energy efficiency improvements

  11. Biomass energy, forests and global warming

    Biomass in all its forms currently provides about 14% of the world's energy, equivalent to 25 million bbl oil/day; in developing countries where it is the major energy source, biomass supplies 35% of total energy use. Although biomass energy use affects the flux of carbon to the atmosphere, the main carbon emission problem is caused by fossil fuels and land clearance for agriculture. Biomass fuels make no net contribution to atmospheric CO 2 if used sustainably. A major global revegetation and reforestation effort is a possible strategy to reduce CO 2 emissions and to slow the pace of climatic change. However, a more attractive alternative strategy might be to substitute fossil fuels, especially coal, with biomass grown specifically for this purpose producing modern fuels such as electricity, liquids and gases. This paper examines biomass energy use, devegetation, biomass burning, the implications for global warming and the ability of biomass to sequester CO 2 and substitute for fossil fuels. It also discusses some socioeconomic and political issues. (author)

  12. Backwardation in energy futures markets: Metalgesellschaft revisited

    2003-01-01

    Energy supply contracts negotiated by the US Subsidiary of Metalgesellschaft Refining and Marketing (MGRM), which were the subject of much subsequent debate, are re-examined. The contracts were hedged by the US Subsidiary barrel-for-barrel using short-dated energy derivatives. When the hedge program experienced difficulties, the derivatives positions were promptly liquidated by the parent company. Revisiting the MGRM contracts also provides the opportunity to explore the latest evidence on backwardation in energy markets. Accordingly, the paper discusses first the theoretical reasons for backwardation, followed by an empirical examination using the MGRM data available at the time of the hedge program in 1992 and a second set of data that became available in 2000. By using a more up-to-date data set covering a longer time period and by controlling the time series properties of the data, the authors expect to provide more reliable empirical evidence on the behaviour of energy futures prices. Results based on the 1992 data suggest that the strategy employed by MGRM could be expected to be profitable while the risks are relatively low. However, analysis based on the 2000 data shows lower, although still significant profits, but higher risks. The final conclusion was that the likelihood of problems similar to those faced by MGRM in 1992 are twice as high with the updated 2000 data, suggesting that the risk-return pattern of the stack-and-roll hedging strategy using short-dated energy future contracts to hedge long-tem contracts is less appealing now than when MGRM implemented its hedging program in 1992. 24 refs., 3 tabs., 6 figs

  15. Scaling future tropical cyclone damage with global mean temperature

    2017-12-01

    Tropical cyclones (TC) are one of the most damaging natural hazards and severely affectmany countries around the globe each year. Their nominal impact is projected to increasesubstantially as the exposed coastal population grows, per capita income increases, andanthropogenic climate change manifests. The magnitude of this increase, however, variesacross regions and is obscured by the stochastic behaviour of TCs, so far impeding arigorous quantification of trends in TC damage with global mean temperature (GMT) rise. Here, we build on the large sample of spatially explicit TCs simulations generated withinISIMIP(2b) for 1) pre-industrial conditions, 2) the historical period, and 3) future projectionsunder RCP2.6 and RCP6.0 to estimate future TC damage assuming fixed present-daysocio-economic conditions or SSP-based future projections of population patterns andincome. Damage estimates will be based on region-specific empirical damage modelsderived from reported damages and accounting for regional characteristics of vulnerability.Different combinations of 1) socio-economic drivers with pre-industrial climate or 2) changingclimate with fixed socio-economic conditions will be used to derive functional relationshipsbetween regionally aggregated changes in damages on one hand and global meantemperature and socio-economic predictors on the other hand. The obtained region-specific scaling of future TC damage with GMT provides valuable inputfor IPCC's special report on the impacts of global warming of 1.5°C by quantifying theincremental changes in impact with global warming. The approach allows for an update ofdamage functions used in integrated assessment models, and contributes to assessing theadequateness of climate mitigation and adaptation strategies.

  16. Estimating current and future global urban domestic material consumption

    Baynes, Timothy Malcolm; Kaviti Musango, Josephine

    2018-06-01

    Urban material resource requirements are significant at the global level and these are expected to expand with future urban population growth. However, there are no global scale studies on the future material consumption of urban areas. This paper provides estimates of global urban domestic material consumption (DMC) in 2050 using three approaches based on: current gross statistics; a regression model; and a transition theoretic logistic model. All methods use UN urban population projections and assume a simple ‘business-as-usual’ scenario wherein historical aggregate trends in income and material flow continue into the future. A collation of data for 152 cities provided a year 2000 world average DMC/capita estimate, 12 tons/person/year (±22%), which we combined with UN population projections to produce a first-order estimation of urban DMC at 2050 of ~73 billion tons/year (±22%). Urban DMC/capita was found to be significantly correlated (R 2 > 0.9) to urban GDP/capita and area per person through a power law relation used to obtain a second estimate of 106 billion tons (±33%) in 2050. The inelastic exponent of the power law indicates a global tendency for relative decoupling of direct urban material consumption with increasing income. These estimates are global and influenced by the current proportion of developed-world cities in the global population of cities (and in our sample data). A third method employed a logistic model of transitions in urban DMC/capita with regional resolution. This method estimated global urban DMC to rise from approximately 40 billion tons/year in 2010 to ~90 billion tons/year in 2050 (modelled range: 66–111 billion tons/year). DMC/capita across different regions was estimated to converge from a range of 5–27 tons/person/year in the year 2000 to around 8–17 tons/person/year in 2050. The urban population does not increase proportionally during this period and thus the global average DMC/capita increases from ~12 to ~14 tons

    The World Energy Scenarios: Composing energy futures to 2050 is the result of a three-year study conducted by over 60 experts from nearly 30 countries, with modelling provided by the Paul Scherrer Institute. The report assesses two contrasting policy scenarios, the more consumer driven Jazz scenario and the more voter-driven Symphony scenario with a key differentiator being the ability of countries to pass through the Doha Climate Gateway. The WEC scenarios use an explorative approach to assess what is actually happening in the world now, to help gauge what will happen in the future and the real impact of today's choices on tomorrow's energy landscape. Rather than telling policy-makers and senior energy leaders what to do in order to achieve a specific policy goal, the WEC's World Energy Scenarios allow them to test the key assumptions that decision-makers decide to better shape the energy of tomorrow This document includes the French and English versions of the executive summary and the English version of the full report

    As telehealth plays an even greater role in global health care delivery, it will be increasingly important to develop a strong evidence base of successful, innovative telehealth solutions that can lead to scalable and sustainable telehealth programs. This paper has two aims: (1) to describe the challenges of promoting telehealth implementation to advance adoption and (2) to present a global research agenda for personalized telehealth within chronic disease management. Using evidence from the United States and the European Union, this paper provides a global overview of the current state of telehealth services and benefits, presents fundamental principles that must be addressed to advance the status quo, and provides a framework for current and future research initiatives within telehealth for personalized care, treatment, and prevention. A broad, multinational research agenda can provide a uniform framework for identifying and rapidly replicating best practices, while concurrently fostering global collaboration in the development and rigorous testing of new and emerging telehealth technologies. In this paper, the members of the Transatlantic Telehealth Research Network offer a 12-point research agenda for future telehealth applications within chronic disease management.

    1986-01-01

    First, a brief historical sketch of the progress of industrialized society and the change in the quantity and quality of energy system accompanying it is made. It is likely to see a very unstable oil market in future, and it is irresponsible to continue the use of oil simply by burning it to obtain heat and electricity. This time is the opportunity to complete a new energy transition, preserving oil for more effective utilization. There is no single energy source which is as versatile, easy to transport and to use, and cheap as oil, therefore, the relative merits and demerits of various available resources must be carefully assessed. Natural gas, the green-house effect caused by burning fossil fuel, hydroelectric power, nuclear fission power, solar, biomass, wind and geothermal energies are discussed. The important alternatives for the future are nuclear fission power, biomass, and by the middle of the next century, nuclear fusion energy. A pluralistic system is the best suitable to the complex society of the next century, having about 8 billion population. A scenario representing the contribution of nuclear energy in 2050 is illustrated, but the clouds on the nuclear horizon must be dispelled. (Kako, I.)

    The globally averaged surface temperature of the Earth has increased during the past century by about 0.7°C. Most of the increase can be attributed to the greenhouse effect, the increase in the atmospheric concentration of carbon dioxide that is emitted when fossil fuels are burned to produce energy.The book begins with the important distinction between weather and climate, followed by data showing how carbon dioxide has increased and the incontrovertible evidence that it is caused by burning fossil fuels (i.e., coal, oil, and natural gas). I also address the inevitable skepticism that global

    Dark energy presents us with a challenging puzzle: understanding the new element of physics evident in the acceleration of the expansion of the universe. Type Ia supernovae first detected this acceleration and have been instrumental in breaking the matter dominated universe paradigm, measuring the current acceleration of the expansion, and probing back to the decelerating phase. To further study the nature of dark energy requires understanding of systematic errors entering into any cosmological probe. Type Ia supernovae provide simple, transparent tracers of the expansion history of the universe, and the sources of systematic uncertainties in the supernova measurement have been identified. We briefly review the progress to date and examine the promise of future surveys with large numbers of supernovae and well bounded systematics

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

    Energy is essential for modern life and is a critical resource that we take for granted. Economies and security of nations depend on reliable and cost-effective access. As the world transitions from conventional oil and natural gas to nuclear, renewables, and unconventional sources we are increasingly confronted by many unsettling questions. Will there be enough cheap oil and gas for preserve the standard of living in the developed world and allow the industrializing world to develop? Will renewable sources provide a significant fraction of our energy needs in the near future? Is global warming already happening as a result of our consumption of fossil fuels? If there is a resource crunch before new sources come on line, will there be conflict or global cooperation? This talk will attempt to answer these questions by examining the global oil and gas resources, geopolitics, and key science and technology issues that need to be addressed by the global community with cooperation and a sense of urgency.

    Conditional on the hypothesis that energy futures markets are efficient or rational, this paper uses Fama's regression approach to measure the information in energy futures prices about future spot prices and time varying premiums. The paper finds that the premium and expected future spot price components of energy futures prices are negatively correlated and that most of the variation in futures prices is variation in expected premiums.

    McKitrick, Ross

    2017-01-01

    Governments around the world have pledged to eliminate or sharply reduce subsidies to energy firms in order to increase economic efficiency and reduce environmental externalities. Yet definitions of subsidies vary widely and, as a result, estimates of their global magnitude vary by orders of magnitude. I review why energy subsidies are so difficult to define and measure. I show why some non-standard measures are very poor proxies for subsidy costs and in fact may vary inversely with them. In particular, recent attempts to treat unpriced externalities as subsidies yield especially misleading results. In general, energy subsidies as conventionally understood do exist but only comprise a small portion of some very large recently-reported estimates, the bulk of which are indirect measures that may have little connection with actual costs to governments or allocational inefficiencies. - Highlights: • Estimates of national and global energy subsidies vary widely. • Microeconomic tools help clarify the various definitions in use. • Some indirect measures are invalid as proxies for normal subsidy costs. • Distorting subsidies do exist but are likely on the low end of some recent reports.

    1987-11-20

    This report proposes solar energy utilizing technologies for future cities, centering on a system that uses Fresnel lenses and optical fiber cables. This system selects out beams in the visible range and the energy can be sent to end terminals constantly as long as sunlight is available. Optical energy is concentrated 4,000-fold. The system can provide long-distance projection of parallel rays. It will be helpful for efficient utilization of light in cities and can increase the degree of freedom in carrying out urban development. The total efficiency for the introduction into optical fiber can be up to 40 percent. With no heating coil incorporated, there is no danger of fire. The standard size of a light condenser is 2 m in dome diameter and 2.5 m in height. Auxiliary artificial light is used for backup purposes when it is cloudy. Heat pumps operating on solar thermal energy are employed to maintain air conditioning for 24 hours a day in order to ensure the establishment of an environment where residential areas exist in the neighborhood of office areas. Seven automatic solar light collection and transfer systems are currently in practical use at the Arc Hills building. The combination of Fresnel lens and optical fiber is more than six times as high in efficiency as a reflecting mirror. (5 figs, 3 tabs, 8 photos, 6 refs)

  12. Future Transportation with Smart Grids and Sustainable Energy

    2009-10-01

    Full Text Available Transportation is facing fundamental change due to the rapid depletion of fossil fuels, environmental and health problems, the growing world population, rising standards of living with more individual mobility and the globalization of trade with its increasing international transport volume. To cope with these serious problems benign, renewable energy systems and much more efficient drives must be multiplied as rapidly as possible to replace the polluting combustion engines with their much too low efficiency and high fuel logistics cost. Consequently the vehicles of the future must be non-polluting and super-efficient, i.e. electric. The energy supply must come via smart grids from clean energy sources not affecting the health, climate and biosphere. It is shown how this transition to the clean, sustainable energy age is possible, feasible and why it is urgent. The important role of international ISO, IEC and ITU standards and the need for better legislation by means of the Global Energy Charter for Sustainable Development are also highlighted.

  13. Ethics and the future of nuclear energy

    Alonso, A.

    2000-01-01

    In democratic societies the future of nuclear energy should be considered as a strategic issue for the country and it should therefore be rationally discussed from every angle, including the moral aspects; within their own political parties, politicians should be leading such discussions. The potentialities of nuclear technology to comply with and respect the human rights, including those of future generations, need to-be evaluated. The social obligation of increasing the well-being of the civil society through the availability of sufficient and reliable electrical energy should be considered a primary condition. The risks associated to nuclear power plants and related activities must be recognized and the nature and functions of regulatory organizations discussed, mainly their independence of judgement. A set of ethical principles regarding communications need to be in place to assure democratic decisions. All concerned parties should participate with the best of the intentions. The human rights of the third generation, those related to the environment, should be given the needed attention, to prevent that the vanguards of the new revolutionary movement of ecologists produce unnecessary victims within the nuclear power plants

  14. Governing Global Climate Change: Past Achievements, Future Prospects

    Directory of Open Access Journals (Sweden)

    Ella Kokotsis

    2014-11-01

    Full Text Available The cumulative effects of a significantly changing climate are projected to have disastrous implications on the world’s natural habitats, and along with that, are projected to drastically increase the rate and likelihood of violent conflict globally, particularly in high-density, urban, poverty hotspots. Limiting the effects of a changing climate is thus critical in influencing multiple societal goals including equitable sustainable development, human health, biodiversity, food security and access to reliable energy sources. This paper argues that the G7/8 has led global climate governance in ways other international environmental institu­tions have largely failed to do. It has done so largely by placing climate protection at the forefront of its policy objectives, alongside economic, health, energy and security goals, and reaching consensus repeatedly amongst its leaders on the impor­tance of stabilizing emissions through energy efficiency, conservation, investment and technological innovation. Moreover, this chapter argues that the summit’s predominant capability, its constricted participation, democratic convergence and political cohesion – as well as the combined effects of global shocks – have all had positive impacts on the G7/8’s success in mitigating climate change. Following a detailed process-tracing exercise over the summit’s 40-year history in which clear surges and retreats on global climate governance are outlined, this paper concludes by assessing the G7/8’s accountability record on climate mitigation and outlines a set of prescriptive recommendations, allowing for the delivery of a more tangible, coherent, results-driven accountability process for global climate governance.

As an example, we evaluated the life cycle energy use, greenhouse gas (GHG) emissions and aqueous nutrient releases of the whole anthropogenic municipal water cycle starting from raw water extraction to wastewater treatment and reuse/discharge for five municipal water and wastewater systems. The assessed options included conventional centralized services and four alternative options following the principles of source-separation and water fit-for-purpose. The comparative life cycle assessment identified that centralized drinking water supply coupled with blackwater energy recovery and on-site greywater treatment and reuse was the most energyand carbon-efficient water service system evaluated, while the conventional (drinking water and sewerage) centralized system ranked as the most energy- and carbon-intensive system. The electricity generated from blackwater and food residuals co-digestion was estimated to offset at least 40% of life cycle energy consumption for water/waste services. The dry composting toilet option demonstrated the lowest life cycle eutrophication potential. The nutrients in wastewater effluent are the dominating contributors for the eutrophication potential for the assessed system configurations. Among the parameters for which variability

    Bioenergy is energy of biological and renewable origin, normally in the form of purpose-grown energy crops or by-products from agriculture, forestry or fisheries. Biomass provides approximately 11-14% of the world's energy, but there are significant differences between industrialised and developing countries. In many developing countries biomass is the most important energy source. As a global average, biomass provides approximately 35% of developing countries' energy, but there are large regional differences. Many sub-Saharan African countries depend on biomass for up to 90% of their energy indicating that they have little in the way of industry or other modern activities. In the last decade interest in bioenergy has increased in industrialised countries partly due to growing concern about climate change, technological advances in biomass conversion, increasing focus on security of energy supply, and increasing interest in renewable energy generally. Two trends emerge: The developing countries will in general aim to reduce their dependence on traditional bioenergy. The relative share of bioenergy in the energy balance will therefore go down, though the number of people depending on traditional bioenergy probably will remain constant, with corresponding consequences for health and resources. Industrialised countries, plus a number of developing countries, will aim to increase their use of modern bioenergy technologies. With the traditional association of bioenergy as old fashioned and for the poor, the recent interest in biomass resources has invented a new term 'modern bioenergy' which covers a number of technological areas from combustion at domestic, industrial or power plant scale, gasification, hydrolysis, pyrolysis, extraction, digestion etc. There are some barriers to the increased use of bioenergy, but they can be overcome through dedicated interventions by public and private sector entities.

    In spite of future uncertainty, Korea is very much committed to nuclear energy as a major source of electric power expansion, because of its lack of domestic energy resources. A long term nuclear power program has resulted in 11 nuclear power plants of 9.6 GWe in operation, 2 units under construction and 7 planned. This means that the share of nuclear power in Korean electricity production would be about 38% in 2006. Many other countries were faced with the problem of global warming which is related to carbondioxide emission from the use of fossil fuels. According to Korean experience, it could be concluded that substitution of fossil fuels would be the most efficient and economic means of reducing the greenhouse gas emissions. In addition to nuclear and hydropower, the most promising other non-fossil sources are geothermal energy, biomass, solar thermal energy, photovoltaic systems, wind power, tidal power, wave power and ocean thermal electric conversion

    Energetic Neutral Atom (ENA) imaging is the only technique that can capture the instantaneous global state of energetic ion distributions in planetary magnetospheres and from the heliosheath. In particular at Earth, ENA imaging has been used to diagnose the morphology and dynamics of the ring current and plasma sheet down to several minutes time resolution and is therefore a critical tool to validate global ring current physics models. However, this requires a detailed understanding for how ENAs are produced from the ring current and inversion techniques that are thoroughly validated against in-situ measurements. To date, several missions have carried out planetary and heliospheric ENA imaging including Cassini, JUICE, IBEX of the heliosphere, and POLAR, Astrid-1, Double Star, TWINS and IMAGE of the terrestrial magnetosphere. Because of their path-finding successes, a future global-imaging mission concept, MEDICI, has been recommended in the Heliophysics Decadal Survey. Its core mission consists of two satellites in one circular, near-polar orbit beyond the radiation belts at around 8 RE, with ENA, EUV and FUV cameras. This recommendation has driven the definition of smaller mission concepts that address specific science aspects of the MEDICI concept. In this presentation, we review the past scientific achievements of ENA imaging with a focus on the terrestrial magnetosphere from primarily the NASA IMAGE and the TWINS missions. The highlighted achievements include the storm, sub-storm and quiet-time morphology, dynamics and pitch-angle distributions of the ring current, global differential acceleration of protons versus O+ ions, the structure of the global electrical current systems associated with the plasma pressure of protons and O+ ions up to around 200 keV, and the relation between ring current and plasmasphere. We discuss the need for future global observations of the ring current, plasma sheet and magnetosheath ion distributions based and derive their

    Worldwide glacier retreat and associated future runoff changes raise major concerns over the sustainability of global water resources1-4, but global-scale assessments of glacier decline and the resulting hydrological consequences are scarce5,6. Here we compute global glacier runoff changes for 56 large-scale glacierized drainage basins to 2100 and analyse the glacial impact on streamflow. In roughly half of the investigated basins, the modelled annual glacier runoff continues to rise until a maximum (`peak water') is reached, beyond which runoff steadily declines. In the remaining basins, this tipping point has already been passed. Peak water occurs later in basins with larger glaciers and higher ice-cover fractions. Typically, future glacier runoff increases in early summer but decreases in late summer. Although most of the 56 basins have less than 2% ice coverage, by 2100 one-third of them might experience runoff decreases greater than 10% due to glacier mass loss in at least one month of the melt season, with the largest reductions in central Asia and the Andes. We conclude that, even in large-scale basins with minimal ice-cover fraction, the downstream hydrological effects of continued glacier wastage can be substantial, but the magnitudes vary greatly among basins and throughout the melt season.

    Extensive fossil fuel consumption in almost all human activities led to some undesirable phenomena such as atmospheric and environmental pollutions, which have not been experienced before in known human history. Consequently, global warming, greenhouse affect, climate change, ozone layer depletion and acid rain terminologies started to appear in the literature frequently. Since 1970, it has been understood scientifically by experiments and researches that these phenomena are closely related to fossil fuel uses because they emit greenhouse gases such as carbon dioxide (CO{sub 2}) and methane (CH{sub 4}) which hinder the long wave terrestrial radiation to escape into space, and consequently, the earth troposphere becomes warmer. In order to avoid further impacts of these phenomena, the two concentrative alternatives are either to improve the fossil fuel quality with reductions in their harmful emissions into the atmosphere or more significantly to replace fossil fuel usage as much as possible with environmentally friendly, clean and renewable energy sources. Among these sources, solar energy comes at the top of the list due to its abundance, and more evenly distribution in nature than any other renewable energy types such as wind, geothermal, hydro, wave and tidal energies. It must be the main and common purpose of humanity to sustain environment for the betterment of future generations with sustainable energy developments. On the other hand, the known limits of fossil fuels compel the societies of the world in the long run to work jointly for their gradual replacement by renewable energy alternatives rather than the quality improvement of fossil sources. Solar radiation is an integral part of different renewable energy resources. It is the main and continuous input variable from practically inexhaustible sun. Solar energy is expected to play a very significant role in the future especially in developing countries, but it has also potential prospects for developed

  1. Multifactor valuation models of energy futures and options on futures

    Science.gov (United States)

    Bertus, Mark J.

    The intent of this dissertation is to investigate continuous time pricing models for commodity derivative contracts that consider mean reversion. The motivation for pricing commodity futures and option on futures contracts leads to improved practical risk management techniques in markets where uncertainty is increasing. In the dissertation closed-form solutions to mean reverting one-factor, two-factor, three-factor Brownian motions are developed for futures contracts. These solutions are obtained through risk neutral pricing methods that yield tractable expressions for futures prices, which are linear in the state variables, hence making them attractive for estimation. These functions, however, are expressed in terms of latent variables (i.e. spot prices, convenience yield) which complicate the estimation of the futures pricing equation. To address this complication a discussion on Dynamic factor analysis is given. This procedure documents latent variables using a Kalman filter and illustrations show how this technique may be used for the analysis. In addition, to the futures contracts closed form solutions for two option models are obtained. Solutions to the one- and two-factor models are tailored solutions of the Black-Scholes pricing model. Furthermore, since these contracts are written on the futures contracts, they too are influenced by the same underlying parameters of the state variables used to price the futures contracts. To conclude, the analysis finishes with an investigation of commodity futures options that incorporate random discrete jumps.

    The Wild Fire Automated Biomass Burning Algorithm (WF_ABBA), developed at the Cooperative Institute for Meteorological Satellite Studies (CIMSS), has a long legacy of operational near real-time wildfire detection and characterization in the Western Hemisphere. The first phase of the global geostationary WF_ABBA was made operational at NOAA NESDIS in 2009 and currently includes diurnal active fire monitoring from GOES-East, GOES-South America, GOES-West, Meteosat-9 and MTSAT-1R/-2. This allows for near global active fire monitoring with coverage of Europe, Africa, Southeast Asia and the Western Pacific utilizing distinct geostationary sensors and a consistent algorithm. Version 6.5.006 of the WF_ABBA was specifically designed to address the capabilities and limitations of diverse geostationary sensors and requests from the global fire monitoring and user community. This presentation will provide an overview of version 6.5.006 of the global WF_ABBA fire product including the new fire and opaque cloud mask and associated metadata. We will demonstrate the WF_ABBA showing examples from around the globe with a focus on the capabilities and plans for integrating new geostationary platforms with coverage of Eastern Europe and Asia (INSAT-3D, Korean COMS, Russian GOMS Elektro-L MSU-GS). We are also preparing for future fire monitoring in the Western Hemisphere, Europe, and Africa utilizing the next generation GOES-R Imager and Meteosat Third Generation Flexible Combined Imager (MTG - FCI). The goal is to create a globally consistent long-term fire product utilizing the capabilities of each of these unique operational systems and a common fire detection algorithm. On an international level, development of a global geostationary fire monitoring system is supported by the IGOS GOFC/GOLD Fire Implementation Team. This work also generally supports Committee on Earth Observation Satellites (CEOS) activities and the Group on Earth Observations (GEO).

  3. The role of the Arctic in future global petroleum supply

    The Arctic has a substantial share of global petroleum resources, but at higher costs than in most other petroleum provinces. Arctic states and petroleum companies are carefully considering the potential for future extraction in the Arctic. This paper studies the oil and gas supply from 6 arctic regions during 2010-2050 along with global economic growth and different assumptions regarding petroleum prices and resource endowments. Supply is calculated based on a global model of oil and gas markets. The data on undiscovered resources for the Arctic is based on the estimates by USGS. Sensitivity studies are carried out for two alternative price scenarios and for a 50 per cent reduction of arctic undiscovered resources compared with the USGS 2008 resource estimate. Although a major part of the undiscovered arctic petroleum resources is natural gas, our results show that the relative importance of the Arctic as a world gas supplier will decline, while its importance as a global oil producer may be maintained. We also show that less than full access to undiscovered oil resources will have minor effect on total arctic oil production and a marginal effect on arctic gas extraction. The reason is that Arctic Russia is an important petroleum producer with a sufficiently large stock of already discovered resources to support their petroleum production before 2050. (Author)

    Georeferenced information on road infrastructure is essential for spatial planning, socio-economic assessments and environmental impact analyses. Yet current global road maps are typically outdated or characterized by spatial bias in coverage. In the Global Roads Inventory Project we gathered, harmonized and integrated nearly 60 geospatial datasets on road infrastructure into a global roads dataset. The resulting dataset covers 222 countries and includes over 21 million km of roads, which is two to three times the total length in the currently best available country-based global roads datasets. We then related total road length per country to country area, population density, GDP and OECD membership, resulting in a regression model with adjusted R 2 of 0.90, and found that that the highest road densities are associated with densely populated and wealthier countries. Applying our regression model to future population densities and GDP estimates from the Shared Socioeconomic Pathway (SSP) scenarios, we obtained a tentative estimate of 3.0–4.7 million km additional road length for the year 2050. Large increases in road length were projected for developing nations in some of the world’s last remaining wilderness areas, such as the Amazon, the Congo basin and New Guinea. This highlights the need for accurate spatial road datasets to underpin strategic spatial planning in order to reduce the impacts of roads in remaining pristine ecosystems.

    Twenty-two papers on the study of tsunamis are included in Volume II of the PAGEOPH topical issue "Global Tsunami Science: Past and Future". Volume I of this topical issue was published as PAGEOPH, vol. 173, No. 12, 2016 (Eds., E. L. Geist, H. M. Fritz, A. B. Rabinovich, and Y. Tanioka). Three papers in Volume II focus on details of the 2011 and 2016 tsunami-generating earthquakes offshore of Tohoku, Japan. The next six papers describe important case studies and observations of recent and historical events. Four papers related to tsunami hazard assessment are followed by three papers on tsunami hydrodynamics and numerical modelling. Three papers discuss problems of tsunami warning and real-time forecasting. The final set of three papers importantly investigates tsunamis generated by non-seismic sources: volcanic explosions, landslides, and meteorological disturbances. Collectively, this volume highlights contemporary trends in global tsunami research, both fundamental and applied toward hazard assessment and mitigation.

    Research into alternative energy sources is being undertaken by several of the large petroleum companies, including PanCanadian Petroleum, PetroCanada, Royal Dutch Shell, BP and Suncor Energy, an indication of the anticipated importance of renewables in the energy mix of the future. Clean electricity generation facilities fuelled by natural gas is one of the areas of interest to PanCanadian Petroleum and TransCanada Pipelines, while PetroCanada is diversifying into biofuels. Worldwide, Royal Dutch Shell has proclaimed renewables as one of its core businesses, budgeting US$500 million for renewable energy research over the next five years. BPSolarex, a subsidiary of British Petroleum, is well on the way to becoming the world's largest manufacturer and marketer of solar technology, while Suncor Energy of Calgary earmarked $100 million over the next five years to research in producing fuel from biomass, conversion of waste to energy, capture of carbon dioxide, and solar and wind power. The driving force behind these efforts is the significant global pressure to reduce greenhouse gas emissions and to meet the commitments undertaken at the 1997 Kyoto Climate Change Conference. Equally important is the recognition of the finite character of conventional energy sources, and the the various scenarios designed by diverse organizations to show the impact of new energy technologies on how people live and work, and how people, goods and resources move. For example, the scenarios developed by the Energy Technologies Futures Program of Natural Resources Canada are designed to provoke discussion of strategic directions and to challenge current thinking about energy consumption, efficiency and conservation. These scenarios identifiy a range of possible outcomes, depending on industry and government efforts to balance the pillars of sustainable development, i. e. the economy, society and the environment.

    The researches have shown that the potential of renewable energy sources is huge as they can in principle meet many times the world's energy demand. Renewable energy sources such as biomass, wind, solar, hydropower and geothermal can provide energy services based on the use of local available resources. Starting from this fact, a transition to renewable-based energy systems is looking increasingly likely as their costs have dropped while the price of oil and gas continue to fluctuate. In the past 30 years, the sales of solar and wind energy systems continued to increase because the capital and electricity production costs decreased simultaneously with the performance enhancement. It is becoming clear that future growth in the energy sector will be primarily in the renewable energy systems and to some extent natural gas-based systems and not in conventional oil and coal sources. It is also important to have governmental assistance and popular support in developing these alternate energy sources, that among others, reduce local and global atmospheric emissions, provide commercially attractive options, particularly in developing countries and rural areas and create the transition to the energy sector of the future. This paper tries to approach the renewable energy sources currently analyzed by the experts, emphasizing their strengths and weaknesses. The conventional energy sources based on oil, coal and natural gas have proven to be highly effective drivers of economic progress but at the same time damaging to the environment and human health. Furthermore they tend to be cyclical in nature, due to the effects of oligopoly in production and distribution. These traditional fossil fuel-based energy sources are facing increasing pressure on environmental issues, among these the future reduction of greenhouse gas specified in the Kyoto Protocol. Renewable energy sources currently supply between 15 - 20% of world's total energy demand. This supply is dominated by biomass

    The alarming effects, concerns, and even the insights into long-range energy planning that grew out of the OPEC oil embargo of 1973 are fading from the view of a shortsighted public. The enthusiastic initiatives taken in many countries for the development of alternative energy sources have withered due to lack of economic and/or ideological incentive. The events since December 1985, when the members of OPEC decided to increase production in an effort to capture their share of market, have brought down the prices of a barrel of crude to less than US $11 and have made any rational analysis very complex. This has made even the proponents of the alternative energy sources pause and think. The US has, as usual, oscillated from panic to complacency. The Libyan crisis, however, has brought the dangers of complacency into sharp focus. The first commercial coal gasification plant, constructed with a capital investment of over US $2 billion, was abandoned by the owners and is being operated by the US Department of Energy temporarily. In their effort to find a private owner, the US Department of Energy has set the date of auction of this prestigious plant for May 28, 1986. And if an appropriate bid is not forthcoming, the plant faces a very uncertain future. Coal, considered by the World Coal Study (WOCOL) at MIT in 1980, to be a bridge to a global energy future, seems to have lost its luster due to the oil glut which we all know is temporary. This was evident when the bill to grant the Right of Eminent Domain for transportation of coal was defeated. This conference was organized to bring together experts in different areas from various countries to discuss the state of the art and the rate of progress in different alternative energy forms. The recent accident at the Chernobyl nuclear power plant in USSR has brought home the need of diversification of the alternative energy sources.

    The task of reducing CO 2 emission in order to keep the global temperature increase below 2 0 C requires staggering changes in energy consumption and production. It appears, unfortunately, that before obvious and drastic effects of climate change occur, few governments have the strength to implement the energy strategies called for. However, by the time climate change becomes evident to wide public it may be too late or much more difficult. Energy policy is heavily politicized which creates another obstacle to timely action, as witnessed by backlash against nuclear energy following Fukushima accidents. Post Fukushima arguments for nuclear energy should concentrate on the features which give it a secure place in the 21st century energy strategy, with highest safety standards understood. Its modern relevance comes from the, at present, unique ability, independent on external conditions, to produce large amounts of energy without emission of carbon dioxide. How long will this unique position last cannot be predicted with precision, but from the dynamics of their developments, large scale CCS is unlikely to be available before 2060/65 and nuclear fusion later still. We discuss the feasibility and desirability of the future without nuclear energy. Our recent study (EP 2010) has shown that nuclear energy, even subject to stringent safety and technology constraints, can give substantial contribution to carbon emission reduction until 2065, thus providing time for a large scale introduction of renewable sources, CCS and possibly nuclear fusion. Maximum nuclear strategy limited by uranium resources and with conventional reactor technology without reprocessing we assumed in period 2025-2065, would contribute in 2065 with about 25.2 Gt CO 2 emission reduction, respectively with 39% of the reduction needed to reduce emission from business as usual strategy (WEO 2009) to the level required to limit global temperature increase below 2 0 C. Remaining reduction of 38.4 Gt C0 2 eq

    This article is a short review on the subject of diminishing mineral resources in a world with increasing population. The concepts of reserves, resources, and life index are described. A forecast is made on the global consumption in the year 2050 of the metals iron (Fe), aluminum (Al), copper (Cu), zinc (Zn), nickel (Ni), and lead (Pb). Evidence indicates that a physical depletion of metals does not occur (fixed stock paradigm) but certain metals will become too expensive to extract (opportunity cost paradigm). The future demand for cadmium (Cd), mercury (Hg), arsenic (As), and selenium (Se) is presented. Finally, some metals presently of great interest for mineral prospectors that may have an important role in the future society are presented.

    2009-03-01

    In the next few years political decisions lie ahead in Sweden and the EU regarding the detailed formulation of the EU's so-called 20-20-20 targets and accompanying EU directives. Talks on a new international post-2012 climate agreement are imminent. The EU targets involve reducing emissions of greenhouse gases by 20 per cent, increasing the proportion of renewable energy by 20 per cent and improving energy efficiency by 20 per cent - all by the year 2020. According to the analysis of the consequences of the targets that the Technology Development Group has commissioned, the reduction in carbon dioxide in the stationary energy system in the Nordic region will be 40 per cent, not 20 per cent, if all the EU targets are to be achieved. The biggest socio-economic cost is associated with achieving the efficiency target, followed by the costs associated with achieving the renewable energy target and the CO 2 target. On the basis of this analysis and compilations about technology development, we want to highlight the following important key issues: Does Sweden want to have the option of nuclear power in the future or not? How to choose good policy instruments for new electricity production and networks? How best to reduce the carbon dioxide emissions of the transport sector and how to develop control and incentive measures that promote such a development? We are proposing the following: Carry out a more in-depth analysis of the consequences of the EU targets, so that the policy instruments produce the best combination as regards climate, economy and security of supply. To achieve the EU targets would require large investments in electricity production, particularly renewable energy, and in electricity networks. Internationally harmonized policy instruments and other incentive measures are required in order for the necessary investments to take place. The policy instruments have to provide a level playing field for all players in the energy sector. The large investments

    Khanna, Neha

    The dissertation comprises four papers that explore the interactions between global warming, energy use, and economic growth. While the papers are separate entities, they share the underlying theme of highlighting national differences in the growth experience and their implications for long-term energy use and climate change. The first paper provides an overview of some key economic issues in the climate change literature. In doing so, the paper critically appraises the 1995 draft report of Working Group III of the Intergovernmental Panel on Climate Change. The focus is the choice of a pure rate of time preference in the economic modeling of climate change, abatement costs differentials between developed and developing countries, and contrasting implications of standard discount rates and value of life estimates for these two country groups. The second paper develops a global model that takes account of the depletion of oil resources in the context of a geo-economic model for climate change. It is found that in the presence of non-decreasing carbon and energy intensities and declining petroleum availability, the carbon emissions trajectory is much higher than that typically projected by other models of this genre. Furthermore, by introducing price and income sensitive demand functions for fossil fuels, the model provides a framework to assess the effectiveness of fuel specific carbon taxes in reducing the COsb2 emissions trajectory. Cross-price substitution effects necessitate unrealistically high tax rates in order to lower the projected emissions trajectory to the optimal level. The economic structure of five integrated assessment models for climate change is reviewed in the third paper, with a special focus on the macroeconomic and damage assessment modules. The final paper undertakes an econometric estimation of the changing shares of capital, labour, energy, and technical change in explaining the growth patterns of 38 countries.

    The challenge facing Ontario in gaining access to affordable, flexible and reliable energy at a time when energy demand is escalating was discussed. The Durham Strategic Energy Alliance (DSEA) was created in 2005 to position Ontario's Durham Region as a Canadian leader in timely, sustainable and reliable energy solutions. Durham employs about 10,000 workers directly in the energy industry. The region also produces nearly 30 per cent of the province's power from local generating stations. It is also home to an energy focused teaching and research institution at the University of Ontario Institute of Technology. The DSEA is composed of business, industry, government and academic institutions committed to taking action on advancing energy solutions in all aspects of the energy life-cycle. Members have a stake in promoting sustainable energy solutions in energy supply and generation, manufacturing of energy solutions, transmission, distribution, conservation and/or consumption of all forms of energy. Since its creation, the DSEA has taken measures to exploit the energy opportunities in Durham Region and plans to significantly expand its activities in the future, particularly in building commercialization capabilities through an energy cluster. New links and formalized networks will be established to achieve this goal. Innovative networks will be developed to connect Durham's academic community with business, industry and energy clusters which are developing globally. The overall DSEA strategy is to develop Durham's energy cluster so that it evolves quickly into Ontario's energy commercialization center. There are three areas where such strategy will be recognized: energy technology adoption/demonstration centre; energy technology adoption officer; and, energy cluster outreach/network. 1 fig

    Wilderness areas in the world are threatened by the environmental impacts of the growing global human population. This study estimates the impact of birth rate on the future surface area of biodiverse wilderness and on the proportion of this area without major extinctions. The following four drivers are considered: human population growth (1), agricultural efficiency (2), groundwater drawdown by irrigation (3), and non-agricultural space used by humans (buildings, gardens, roads, etc.) (4). This study indicates that the surface area of biodiverse unmanaged land will reduce with about 5.4% between 2012 and 2050. Further, it indicates that the biodiverse land without major extinctions will reduce with about 10.5%. These percentages are based on a commonly used population trajectory which assumes that birth rates across the globe will reduce in a similar way as has occurred in the past in many developed countries. Future birth rate is however very uncertain. Plausible future birth rates lower than the expected rates lead to much smaller reductions in surface area of biodiverse unmanaged land (0.7% as opposed to 5.4%), and a reduction in the biodiverse land without major extinctions of about 5.6% (as opposed to 10.5%). This indicates that birth rate is an important factor influencing the quality and quantity of wilderness remaining in the future.

    Decision makers have to increasingly balance the costs versus benefits of various energy choices against a background of global environmental deterioration. This is particularly so in the choice of long term electricity production strategies where these have to be balanced against the potential of a very severe disruption of the world's climate due to global warming. In this presentation, the threat of global warming is quantified and scenarios are developed of future predicted energy consumption patterns and their impact on international policies to curb global warming, are analyzed. The conclusion is reached that the threat of global warming is so severe that, on the macro level, an international accepted strategy of utilising a proper balance between all forms of electricity production, is a matter of priority and that all national energy choices should be taken against this framework. Such strategic decisions on the macro level must, however, also translate into the micro level of energy production on topics which include: - more efficient plant utilisation; - more effective risk management; correct choice and application of technology; and - better understanding of issues concerning safety, quality and environmental impact.

    Scenario analysis articulates our hopes and fears for the future. It should help in understanding the nature of the driving events and forces affecting the future and the uncertainties determining their potential impacts. Two major events would dramatically change the urgency and direction of energy innovation in Europe: the arrival of a global peak in oil production and the failure of global climate change policies. The first part of this essay deals with the plausibility of such driving events. On the basis of a critical look at the arguments of the oil peak doomsayers and the environmental anti-globalists it is concluded that both events are plausible and would have major consequences for energy transitions in Europe. Accordingly, the future course of European energy transitions is described in four contrasting scenarios: FIREWALLED EUROPE - Oil production peaks in the period 2010-2020. No viable post-Kyoto climate change policy emerges. The European energy sector turns back to coal and nuclear in the next 50 years; FOSSIL TRADE - Oil production follows oil demand smoothly in the period 2010-2020. No viable post-Kyoto climate change policy emerges. The European energy sector continues business as usual in the next 50 years; SUSTAINABLE TRADE - Oil production peaks in the period 2010-2020. Post-Kyoto climate policies develop effectively. The European energy sector turns to large-scale trade in renewables in the next 50 years; and FENCELESS EUROPE - Oil production follows oil demand smoothly in the period 2010-2020. Post-Kyoto climate policies develop effectively. The European energy sector diversifies strongly keeping all options open for the next 50 years. The major part of this essay concerns the storylines for these four scenarios at the global level of socio-political landscapes, at the European level of energy regime transitions and at the national level for innovation systems. As the names of the scenarios suggest the-prospects for international trade in

    Wind energy is one of the most promising renewable energy sources. Nevertheless, it is not yet a common source of energy, although there is enough wind potential to supply world's energy demand. One of the most prominent obstacles on the way of employing wind energy is the uncertainty associated with wind energy assessment. Global sensitivity analysis (SA) studies how the variation of input parameters in an abstract model effects the variation of the variable of interest or the output variable. It also provides ways to calculate explicit measures of importance of input variables (first order and total effect sensitivity indices) in regard to influence on the variation of the output variable. Two methods of determining the above mentioned indices were applied and compared: the brute force method and the best practice estimation procedure In this study a methodology for conducting global SA of wind energy assessment at a planning stage is proposed. Three sampling strategies which are a part of SA procedure were compared: sampling based on Sobol' sequences (SBSS), Latin hypercube sampling (LHS) and pseudo-random sampling (PRS). A case study of Masdar City, a showcase of sustainable living in the UAE, is used to exemplify application of the proposed methodology. Sources of uncertainty in wind energy assessment are very diverse. In the case study the following were identified as uncertain input parameters: the Weibull shape parameter, the Weibull scale parameter, availability of a wind turbine, lifetime of a turbine, air density, electrical losses, blade losses, ineffective time losses. Ineffective time losses are defined as losses during the time when the actual wind speed is lower than the cut-in speed or higher than the cut-out speed. The output variable in the case study is the lifetime energy production. Most influential factors for lifetime energy production are identified with the ranking of the total effect sensitivity indices. The results of the present

    This paper was originally written in response to the concern that rising levels of CO2 in the atmosphere caused by burning of fossil fuels will ultimately contribute to global warming. Now we are beginning to see evidence of coming problems in the supply of fuels for transportation. This paper describes the benefits of adequate energy supply and the problems of future energy supply. Partial solutions are suggested for immediate application as well as longer term solutions to address both of these concerns. To evaluate the situation and solutions we must understand: (1) how much primary energy is currently used world-wide and might be needed in 2100, (2) how important energy is to the welfare of people, (3) the forms of energy sources and end uses and (4) where new sources may come from. The major portion of world primary energy demand is provided by fossil fuels. This portion dropped from 93% in 1970 to 85% in 1995, mainly because of the increased use of nuclear energy. How ever, since the mid-1990s fossil fuels have maintained their 85% share of world energy supply. The importance of the relationship between per capita energy consumption and per capita income for the world is discussed. The limits of conservation, energy efficiency and renewable energies are examined. The contribution of renewable energies is compared to 41 different views of world energy demand in 2100. Without new technology for large scale storage of intermittent electricity from wind and solar the contribution of renewable energies is not likely to grow significantly beyond the current level of 7-8%. The paper offers conclusions and partial solutions that we can work on immediately. Examination of the forms of energy supplied by the sun, which is powered by nuclear fusion, and the way in which nuclear fission currently supplies energy to the world sets the research framework for longer term solutions.

    Full Text Available Abstract Background Among academic institutions in the United States, interest in global health has grown substantially: by the number of students seeking global health opportunities at all stages of training, and by the increase in institutional partnerships and newly established centers, institutes, and initiatives to house global health programs at undergraduate, public health and medical schools. Witnessing this remarkable growth should compel health educators to question whether the training and guidance that we provide to students today is appropriate, and whether it will be applicable in the next decade and beyond. Given that “global health” did not exist as an academic discipline in the United States 20 years ago, what can we expect it will look like 20 years from now and how can we prepare for that future? Discussion Most clinicians and trainees today recognize the importance of true partnership and capacity building in both directions for successful international collaborations. The challenge is in the execution of these practices. There are projects around the world where this is occurring and equitable partnerships have been established. Based on our experience and observations of the current landscape of academic global health, we share a perspective on principles of engagement, highlighting instances where partnerships have thrived, and examples of where we, as a global community, have fallen short. Conclusions As the world moves beyond the charity model of global health (and its colonial roots, it is evident that the issue underlying ethical global health practice is partnership and the pursuit of health equity. Thus, achieving equity in global health education and practice ought to be central to our mission as educators and advisors when preparing trainees for careers in this field. Seeking to eliminate health inequities wherever they are ingrained will reveal the injustices around the globe and in our own cities and

    Several factors have led to growing interest in a hydrogen energy economy, especially for transportation. A successful transition to a major role for hydrogen will require much greater cost-effectiveness, fueling infrastructure, consumer acceptance, and a strategy for its basis in renewable energy feedstocks. Despite modest attention to the need for a sustainable hydrogen energy system in several countries, in most cases in the short to mid term hydrogen will be produced from fossil fuels. This paper surveys the global status of hydrogen energy research and development (R and D) and public policy, along with the likely energy mix for making it. The current state of hydrogen energy R and D among auto, energy and fuel-cell companies is also briefly reviewed. Just two major auto companies and two nations have specific targets and timetables for hydrogen fuel cells or vehicle production, although the EU also has an aggressive, less specific strategy. Iceland and Brazil are the only nations where renewable energy feedstocks are envisioned as the major or sole future source of hydrogen. None of these plans, however, are very certain. Thus, serious questions about the sustainability of a hydrogen economy can be raised

    Anticipating the effect of climate change on biodiversity, in particular on changes in community composition, is crucial for adaptive ecosystem management but remains a critical knowledge gap. Here, we use climate velocity trajectories, together with information on thermal tolerances and habitat preferences, to project changes in global patterns of marine species richness and community composition under IPCC Representative Concentration Pathways (RCPs) 4.5 and 8.5. Our simple, intuitive approach emphasizes climate connectivity, and enables us to model over 12 times as many species as previous studies. We find that range expansions prevail over contractions for both RCPs up to 2100, producing a net local increase in richness globally, and temporal changes in composition, driven by the redistribution rather than the loss of diversity. Conversely, widespread invasions homogenize present-day communities across multiple regions. High extirpation rates are expected regionally (for example, Indo-Pacific), particularly under RCP8.5, leading to strong decreases in richness and the anticipated formation of no-analogue communities where invasions are common. The spatial congruence of these patterns with contemporary human impacts highlights potential areas of future conservation concern. These results strongly suggest that the millennial stability of current global marine diversity patterns, against which conservation plans are assessed, will change rapidly over the course of the century in response to ocean warming.

    serious economical, ecological, and social problems. Trying to evaluate these problems, an attempt was made to foresee trends of further economy development and energy demand for next 20 years. The econometric models, comparative analysis and analytical expertise evaluation methods were used. Three different scenarios of future energy consumption growth were analysed. Results of the performed analysis show, that in the year 2020 energy demand should be about 15,3 - 22,1Twh in cases of the slow or very fast growth scenario (3197 MW and 4484 MW respectively, taking into account necessary reserves). This leads to a shortage of Lithuania's power generating capacity already by 2010. In 2020 this shortage can increase to 556 MW in case of the slow growth scenario and 1843 MW in case of the very fast growth scenario. Three possible ways to compensate this shortage increasing the share of power plants using fossil fuel, broadening the exploitation of renewable energy resources, and nuclear option are analysed. Both economical and ecological problems, including the price dynamics of main imported energy resources, especially of oil and natural gas, are taken into account. It is pointed out that according to Energy Strategy of Russia average contract price of gas can reach 119 - 138 USD/10 3 m 3 in 2020 (growth of price 138 - 160% compared to 86 USD/10 3 m 3 in the year 2000). The unreliability of fuel supply from single supplier (Russia) is emphasized. Analysis and assessment of positive and negative aspects of different energy generation means shows that perhaps the best solution in perspective for Lithuania is the nuclear option. It can be realised by following means: a) extension of exploitation of the second unit of Ignalina NPP after the year 2010, b) replacement of existing RBMK-1500 reactors by modern BWR or PWR reactors, using existing turbines and infrastructure, and c) construction of new nuclear power unit or plant. Results of this study illustrate, that all nuclear

    Leaders of the Group of 8 countries backed the IAEA's work at their annual summit held 15-17 July 2006 in St. Petersburg, Russia. A concluding summary statement endorsed IAEA programmes and initiatives in areas of nuclear safety, security, and safeguards. The G8 nations adopted a St. Petersburg Plan of Action to increase transparency, predictability and stability of the global energy markets, improve the investment climate in the energy sector, promote energy efficiency and energy saving, diversify energy mix, ensure physical safety of critical energy infrastructure, reduce energy poverty and address climate change and sustainable development. In a statement on global energy security, the G8 said countries who have or are considering plans for nuclear energy believe it will contribute to global energy security while reducing air pollution and addressing climate change. The G8 said it acknowledged the efforts made in development by the Generation IV International Forum (GIF) and the IAEA's International Project on Innovative Nuclear Reactors and Fuel Cycles (INPRO). GIF and INPRO both bring together countries to develop next generation nuclear energy systems, including small reactors, very high temperature reactors and supercritical water-cooled reactors. The G8 reaffirmed its full commitment to all three pillars of the NPT and called on all States to comply with their NPT obligations, including IAEA safeguards as well as developing effective measures aimed at preventing trafficking in nuclear equipment, technology and materials. The G8 is seeking universal adherence to IAEA comprehensive safeguards agreements and is actively engaged in efforts to make comprehensive safeguards agreements together with an Additional Protocol the universally accepted verification standard. The G8 noted that an expansion of the peaceful use of nuclear energy must be carried forward in a manner consistent with nuclear non-proliferation commitments and standards. It discussed concrete

    The Surface Water and Ocean Topography (SWOT) mission is designed to provide global observations of water surface elevation and slope from which river discharge can be estimated using a data assimilation system. This mission will provide increased spatial and temporal coverage compared to current altimeters, with an expected accuracy for water level elevations of 10 cm on rivers greater than 100 m wide. Within the 21-day repeat cycle, a river reach will be observed 2-4 times on average. Due to the relationship between the basin orientation and the orbit, these observations are not evenly distributed in time, which will impact the derived discharge values. There is, then, a need for a better understanding of how the mission will observe global river basins. In this study, we investigate how SWOT will observe global river basins and how the temporal and spatial sampling impacts the discharge estimated from assimilation. SWOT observations can be assimilated using the Inverse Streamflow Routing (ISR) model of Pan and Wood [2013] with a fixed interval Kalman smoother. Previous work has shown that the ISR assimilation method can be used to reproduce the spatial and temporal dynamics of discharge within many global basins: however, this performance was strongly impacted by the spatial and temporal availability of discharge observations. In this study, we apply the ISR method to 32 global basins with different geometries and crossing patterns for the future orbit, assimilating theoretical SWOT-retrieved "gauges". Results show that the model performance varies significantly across basins and is driven by the orientation, flow distance, and travel time in each. Based on these properties, we quantify the "observability" of each basin and relate this to the performance of the assimilation. Applying this metric globally to a large variety of basins we can gain a better understanding of the impact that SWOT observations may have across basin scales. By determining the

    It is clear that future nuclear systems will operate in an environment that will be very different from the electricity systems that accompanied the fast deployment of nuclear power plants in the 1970's and 1980's. As countries fulfil their commitment to de-carbonise their energy systems, low-carbon sources of electricity and in particular variable renewables, will take large shares of the overall generation capacities. This is challenging since in most cases, the timescale for nuclear technology development is far greater than the speed at which markets and policy/regulation frameworks can change. Nuclear energy, which in OECD countries is still the largest source of low-carbon electricity, has a major role to play as a low-carbon dispatchable technology. In its 2 degree scenarios, the International Energy Agency (IEA) projects that nuclear capacity globally could reach over 900 GW by 2050, with a share of electricity generation rising from less than 11% today to about 16%. Nuclear energy could also play a role in the decarbonization of the heat sector, by targeting non-electric applications. The workshop discussed how energy systems are evolving towards low-carbon systems, what the future of energy market needs are, the changing regulatory framework from both the point of view of safety requirements and environmental constraints, and how reactor developers are taking these into account in their designs. In terms of technology, the scope covered all advanced reactor systems under development today, including evolutionary light water reactors (LWRs), small modular reactors (SMRs) - whether LWR technology-based or not, and Generation IV (Gen IV) systems.

    Full Text Available This article briefly discusses major reasons for the slump of international oil prices and provides a prediction for the future development of international oil prices, before analyzing the three factors leading to significant changes of the global energy system, namely the eastward shift of the world energy consumption centre, the emergence of the United States as a major oil producer and the dramatic waning of the Organization of Petroleum Exporting Countries’ (OPEC influence. These factors and developments are shaping a new order of the global energy strategic landscape and exerting profound influence on China’s international strategic environment. In the foreseeable future, these changes of the global energy system would bring China more uncertainties regarding the country’s oil imports from the Middle East, more strategic pressure from the United States, while promoting China’s leverage on the global energy system and international relations.

    The paper gives a global view of sustainable energy consumption and production both in developed and developing countries. There is a need of replacing fossil fuel sources with renewable energy at a speed parallel to the depletion of the oil and gas sources. According to the author, the actual growth in developing countries` use of oil, coal and other sources of energy has almost tripled since 1970. Future population growth alone will spur a further 70% jump in energy use in 30 years, even if per capita consumption remains at current levels. For the OECD countries, energy use rose one fifth as much as economic growth between 1973 and 1989. Countries like China and India, and other developing countries, have huge coal reserves and energy needs. Policy makers have to integrate environmental concerns in decision making over the choice between different fuels, energy technologies and stricter environmental standards. Life cycle analyses can contribute to the development of overall indicators of environmental performance of different technologies. According to the IPCC (Intergovernmental Panel on Climate Change), anthropogenic CO{sub 2} emissions must be reduced by more than 60% in order to stabilize the CO{sub 2} concentration in the atmosphere. 8 refs.

  18. Role of volcanic forcing on future global carbon cycle

    Full Text Available Using a fully coupled global climate-carbon cycle model, we assess the potential role of volcanic eruptions on future projection of climate change and its associated carbon cycle feedback. The volcanic-like forcings are applied together with a business-as-usual IPCC-A2 carbon emissions scenario. We show that very large volcanic eruptions similar to Tambora lead to short-term substantial global cooling. However, over a long period, smaller eruptions similar to Pinatubo in amplitude, but set to occur frequently, would have a stronger impact on future climate change. In a scenario where the volcanic external forcings are prescribed with a five-year frequency, the induced cooling immediately lower the global temperature by more than one degree before it returns to the warming trend. Therefore, the climate change is approximately delayed by several decades, and by the end of the 21st century, the warming is still below two degrees when compared to the present day period. Our climate-carbon feedback analysis shows that future volcanic eruptions induce positive feedbacks (i.e., more carbon sink on both the terrestrial and oceanic carbon cycle. The feedback signal on the ocean is consistently smaller than the terrestrial counterpart and the feedback strength is proportionally related to the frequency of the volcanic eruption events. The cooler climate reduces the terrestrial heterotrophic respiration in the northern high latitude and increases net primary production in the tropics, which contributes to more than 45 % increase in accumulated carbon uptake over land. The increased solubility of CO2 gas in seawater associated with cooler SST is offset by a reduced CO2 partial pressure gradient between the ocean and the atmosphere, which results in small changes in net ocean carbon uptake. Similarly, there is nearly no change in the seawater buffer capacity simulated between the different volcanic scenarios. Our study shows that even

    Most medium- and long-term energy scenarios foresee the joint development of renewable and nuclear energies. In other words, the energy sources must be as various as possible. Among the renewable energy sources, the solar energy presents the highest development potential, even if today the biomass and wind energies are quantitatively more developed. In France, the solar power generation is ensured by photovoltaic systems. However, the thermodynamical conversion of solar energy (using concentrating systems) represents an enormous potential at the world scale and several projects of solar plants are in progress in Spain and in the USA. The advantages of this solution are numerous: high efficiency of thermodynamic cycles, possibility of heat storage and hybridization (solar/fuels), strong potential of innovation. Moreover, the solar concentrators allow to reach temperatures higher than 1000 deg. C and thus allow to foresee efficient thermochemical cycles for hydrogen generation. The future solar plants will have to be efficient, reliable and will have to be able to meet the energy demand. In order to reach high thermodynamic cycle efficiencies, it is necessary to increase the temperature of the hot source and to design combined cycles. These considerations are common to the communities of researchers and engineers of both the solar thermal and nuclear industries. Therefore, the future development of generation 4 nuclear power plants and of generation 3 solar plants are conditioned by the resolution of similar problems, like the coolants (molten salts and gases), the materials (metals and ceramics), the heat transfers (hydrogen generation), and the qualification of systems (how solar concentrators can help to perform qualification tests of nuclear materials).

  20. Spillover effects in energy futures markets

    Price discovery in crude oil and refined oil products has been extensively undertaken in organised futures markets for over a decade now. There are two dominant such markets today: the first one in the New York Mercantile Exchange; and the second in London's International Petroleum Exchange. With the demise of OPEC as the leading price setter for crude and products, NYMEX light sweet crude and Brent crude have usurped the role of benchmark grades for price setting. To date considerable work has been done to scrutinise the degree to which these two markets price efficiently, but little with regard to the way the two markets interact. Participants in these markets move with relative ease from one market to the other and usually take positions in both of them. It is of interest, therefore, to investigate the information transmission mechanism by looking at spillover effects and, perhaps, identify which market is the true price leader. This paper is a first attempt to look at such a problem in the energy market, although similar studies have been done on stock market indices. It is found that substantial spillover effects do exist when both markets are trading simultaneously, although IPE morning prices seem to be considerably affected by the close of the previous day on NYMEX

  1. Energy mix of the future will be a mosaic

    It is generally acknowledged that while hydrocarbons will remain the leading sources of fuel around the world there is, nevertheless, a growing belief that the world's energy mix is rapidly diversifying. As a result, or as a sign of this diversification, many of the large oil companies are investing large sums of money to investigate and market alternative energy sources. Underlying this activity is the belief that these research and development efforts are key to helping the companies achieve their goal of continuous improvement in environmental performance. Examples are PanCanadian and TransCanada Pipelines diversifying into clean electricity generation facilities fuelled by natural gas; Petro Canada's growing interest in biofuels; Royal Dutch Shell's aggressive incursion into solar power manufacture and installation; BPSolarex's drive to become the largest manufacturer and marketer of solar technology, and Calgary-based Suncor's drive to become a leader in alternative and renewable energy sources by earmarking $100 million for investments in producing fuel from biomass, conversion of waste to energy, capture of carbon dioxide, solar and wind power. Most of these efforts are driven by consumer demand for cleaner sources of energy and increasing global pressure to meet greenhouse gas emission targets established at the 1997 Kyoto Summit. Development of innovative new energy technologies are the key to achieving significant breakthroughs according to the Energy Technologies Futures (ETF) project of Natural Resources Canada. ETF has developed four scenarios that predict Canada's energy mix 30 to 50 years from now and the degree to which new energy technologies will be adopted. The scenarios cover a range of possible outcomes, depending on how the three pillars of sustainable development - economy, society and environment - are balanced by industry and governments. The most promising is called 'Come Together' where industry and

    Is man changing the climate of the Earth, and if so, is this at a global scale? This question with all its reunifications, usually referred to under the heading ''greenhouse effect'', deservedly stands in the focus of public attention. Besides fears and warnings reaching even to disaster scenarios there have recently also been sceptical voices pointing out the imponderabilities of filtering anthropogenic effects out of the climate data. This uncertainty is not surprising to the expert, as natural changes of climate always have, and will, superimpose anthropogenic influences. Therefore, it is not enough to peer into the future with the help of intricate climate models. Diagnostic analysis of the past climate is at least just as important. (orig.) [de

    The possibility of improving the thermal efficiency of energy systems from an exergy point of view is discussed. In total energy systems, we should employ multi-pass recycling consisting of thermal and chemical energies. The recycling system is supported by electrical energy, which is provided by a renewable energy source or by excess commercial electric power. This total energy system should be considered not only in one country, but all around the globe. (author). 6 figs., 4 tabs., 8 refs

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

  6. Reducing global NOx emissions: developing advanced energy and transportation technologies.

    2002-03-01

    Globally, energy demand is projected to continue to increase well into the future. As a result, global NOx emissions are projected to continue on an upward trend for the foreseeable future as developing countries increase their standards of living. While the US has experienced improvements in reducing NOx emissions from stationary and mobile sources to reduce ozone, further progress is needed to reduce the health and ecosystem impacts associated with NOx emissions. In other parts of the world, (in developing countries in particular) NOx emissions have been increasing steadily with the growth in demand for electricity and transportation. Advancements in energy and transportation technologies may help avoid this increase in emissions if appropriate policies are implemented. This paper evaluates commercially available power generation and transportation technologies that produce fewer NOx emissions than conventional technologies, and advanced technologies that are on the 10-year commercialization horizon. Various policy approaches will be evaluated which can be implemented on the regional, national and international levels to promote these advanced technologies and ultimately reduce NOx emissions. The concept of the technology leap is offered as a possibility for the developing world to avoid the projected increases in NOx emissions.

    Global warming potentials (GWPs) are the metrics currently used to compare emissions of different greenhouse gases under the United Nations Framework Convention on Climate Change. Future changes in greenhouse gas concentrations will alter GWPs because the radiative efficiencies of marginal changes in CO{sub 2}, CH{sub 4} and N{sub 2}O depend on their background concentrations, the removal of CO{sub 2} is influenced by climate-carbon cycle feedbacks, and atmospheric residence times of CH{sub 4} and N{sub 2}O also depend on ambient temperature and other environmental changes. We calculated the currently foreseeable future changes in the absolute GWP of CO{sub 2}, which acts as the denominator for the calculation of all GWPs, and specifically the GWPs of CH{sub 4} and N{sub 2}O, along four representative concentration pathways (RCPs) up to the year 2100. We find that the absolute GWP of CO{sub 2} decreases under all RCPs, although for longer time horizons this decrease is smaller than for short time horizons due to increased climate-carbon cycle feedbacks. The 100-year GWP of CH{sub 4} would increase up to 20% under the lowest RCP by 2100 but would decrease by up to 10% by mid-century under the highest RCP. The 100-year GWP of N{sub 2}O would increase by more than 30% by 2100 under the highest RCP but would vary by less than 10% under other scenarios. These changes are not negligible but are mostly smaller than the changes that would result from choosing a different time horizon for GWPs, or from choosing altogether different metrics for comparing greenhouse gas emissions, such as global temperature change potentials.

    In this study, we use a multi-model framework to examine a set of possible future energy scenarios resulting from R&D investments in Solar, Nuclear, Carbon Capture and Storage (CCS), Bio-fuels, Bio-electricity, and Batteries for Electric Transportation. Based on a global scenario analysis, we examine the impact on the economy of advancement in energy technologies, considering both individual technologies and the interactions between pairs of technologies, with a focus on the role of uncertainty. Nuclear and CCS have the most impact on abatement costs, with CCS mostly important at high levels of abatement. We show that CCS and Bio-electricity are complements, while most of the other energy technology pairs are substitutes. We also examine for stochastic dominance between R&D portfolios: given the uncertainty in R&D outcomes, we examine which portfolios would be preferred by all decision-makers, regardless of their attitude toward risk. We observe that portfolios with CCS tend to stochastically dominate those without CCS; and portfolios lacking CCS and Nuclear tend to be stochastically dominated by others. We find that the dominance of CCS becomes even stronger as uncertainty in climate damages increases. Finally, we show that there is significant value in carefully choosing a portfolio, as relatively small portfolios can dominate large portfolios. - Highlights: • We examine future energy scenarios in the face of R&D and climate uncertainty. • We examine the impact of advancement in energy technologies and pairs of technologies. • CCS complements Bio-electricity while most technology pairs are substitutes. • R&D portfolios without CCS are stochastically dominated by portfolios with CCS. • Higher damage uncertainty favors R&D development of CCS and Bio-electricity

    We assess the human health and economic impacts of projected 2000-2050 changes in ozone pollution using the MIT Emissions Prediction and Policy Analysis - Health Effects (EPPA-HE) model, in combination with results from the GEOS-Chem global tropospheric chemistry model of climate and chemistry effects of projected future emissions. We use EPPA-HE to assess the human health damages (including mortality and morbidity) caused by ozone pollution, and quantify their economic impacts in sixteen world regions. We compare the costs of ozone pollution under scenarios with 2000 and 2050 ozone precursor and greenhouse gas emissions (using the Intergovernmental Panel on Climate Change (IPCC) Special Report on Emissions Scenarios (SRES) A1B scenario). We estimate that health costs due to global ozone pollution above pre-industrial levels by 2050 will be $580 billion (year 2000$) and that mortalities from acute exposure will exceed 2 million. We find that previous methodologies underestimate costs of air pollution by more than a third because they do not take into account the long-term, compounding effects of health costs. The economic effects of emissions changes far exceed the influence of climate alone.

    Twenty papers on the study of tsunamis are included in Volume III of the PAGEOPH topical issue "Global Tsunami Science: Past and Future". Volume I of this topical issue was published as PAGEOPH, vol. 173, No. 12, 2016 and Volume II as PAGEOPH, vol. 174, No. 8, 2017. Two papers in Volume III focus on specific details of the 2009 Samoa and the 1923 northern Kamchatka tsunamis; they are followed by three papers related to tsunami hazard assessment for three different regions of the world oceans: South Africa, Pacific coast of Mexico and the northwestern part of the Indian Ocean. The next six papers are on various aspects of tsunami hydrodynamics and numerical modelling, including tsunami edge waves, resonant behaviour of compressible water layer during tsunamigenic earthquakes, dispersive properties of seismic and volcanically generated tsunami waves, tsunami runup on a vertical wall and influence of earthquake rupture velocity on maximum tsunami runup. Four papers discuss problems of tsunami warning and real-time forecasting for Central America, the Mediterranean coast of France, the coast of Peru, and some general problems regarding the optimum use of the DART buoy network for effective real-time tsunami warning in the Pacific Ocean. Two papers describe historical and paleotsunami studies in the Russian Far East. The final set of three papers importantly investigates tsunamis generated by non-seismic sources: asteroid airburst and meteorological disturbances. Collectively, this volume highlights contemporary trends in global tsunami research, both fundamental and applied toward hazard assessment and mitigation.

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

    There is no dearth of information regarding the grave crises faced by humanity in the 21st century. There is also growing consensus that the wholesale burning of fossil fuels must come to an end, either because of climate change or other still-salient reasons such as air pollution or major conflicts over dwindling reserves of cheaply recoverable oil and gas resources. At the same time, global demographics predict with disquieting certainty a world with up to 9 or 10 billion souls by mid-century. The vast expansion of energy consumption that this population represents, along with further increases in already-unacceptable levels of atmospheric carbon dioxide from fossil fuel burning, demands that we quickly develop almost limitless sources of clean, economical power. What is sorely lacking in the public debate are realistic solutions. Expanding wind and solar generating capacity is an important near-term goal, but neither of these technologies represents a viable solution for generating base load power at the vast scales that will be required. Energy efficiency measures are likewise well-directed, but the combination of rising population along with increasingly energy-intensive economic activity by the large fraction of Earth's current population residing in developing nations suggests that absolute energy demand will continue to rise even with radically improved energy efficiency. Fortunately we have the technologies available to provide virtually unlimited clean energy, and to utilize and recycle our resources so that everyone can improve their standard of living. The Integral Fast Reactor (IFR), developed at the Argonne National Laboratory in the 80's and 90's and currently championed by General Electric, is a technology that fills the bill on every count, and then some. IFRs are safe, environmentally clean, economical, and free of conflict over fuel supply. IFRs can safely consume as fuel the nuclear waste from the current installed base of light-water reactors

    2002-01-01

    Full text: Nuclear energy is an established component of electricity supply worldwide (16%) and in particular in OECD (nearly a quarter). It is supported by a mature industry benefiting from extensive experience (more than 8 000 reactor years of commercial operation) and dynamic R and D programmes implemented by governments and industries. Existing nuclear power plants are competing successfully in deregulated electricity markets owing to their low marginal production costs, their technical reliability (availability factors exceeding 80% in many countries) and good safety performance. Stringent safety requirements and radiation protection regulations in place in OECD countries allow potential impacts of nuclear energy facilities on human health and the environment to remain extremely low. Furthermore, nuclear energy, a nearly carbon free source, contributes to alleviating the risk of global climate change (worldwide, GHG emissions from the energy sector are already 8% lower than they would be without nuclear energy). Issues related to high-level waste management and disposal are being addressed in comprehensive, step by step approach. Progress towards the implementation of deep geological repositories is being demonstrated (e.g., Yucca Mountain in the US, Olkiluoto in Finland) and research on innovative fuel cycles aiming at partitioning and transmutation of minor actinides is being actively pursued. Up to 2010-2020, nuclear energy will maintain its role mainly through capacity upgrade and lifetime extension of existing plants, in many cases the most cost effective means to increase power capacity and generation. Examples are provided by utility policies and decisions in a number of OECD countries (e.g., Spain, Sweden, Switzerland, UK, US). Although only few new units are being or will be built in the very near term, their construction and operation is bringing additional experience on advanced evolutionary nuclear systems and paving the way for the renaissance of

    The social or external costs of energy have received a high degree of internatinal attention since the publication of the first empirical results in 1988. Possible global climate change and the call for a sustainable future of mankind have put the question of social costs onto the agenda of many national and international converences like the 'Earth Summit' in Rio 1992. A scientific discussion has been sparked off, searching for the best methodoligical approaches and reliable empirical data. An overview of this discussion was given by the report on the 1st international workshop published in 1991. This book reports on the 2nd international workshop on the subject and gives a broad overview of the discussion in the 25 papers presented. It is the most comprehensive picture of this subject matter avvailable. (orig.)

    Empirical scaling expressions, reflecting the parametric dependence of the L-mode energy confinement time, have been used not only as benchmarks for tokamak operation and theories of energy transport, but for predicting the performance of proposed tokamak devices. Several scaling expressions based on data from small-and medium-sized devices have done well in predicting performance in larger devices, although great uncertainty exists in extrapolating yet farther, into the ignition regime. Several approaches exist for developing higher confidence scaling expressions. These include reducing the statistical uncertainty by identifying and filling in gaps in the present database, making use of more sophisticated statistical techniques, and developing scalings for confinement regimes within which future devices will operate. Confidence in the scaling expressions will be increased still if the expressions can be more directly tied to transport physics theory. This can be done through the use of dimensionless parameters, better describing the edge and core confinement regimes separately, and by incorporating transport models directly into the scaling expressions. 50 refs., 5 figs., 3 tabs

    Over the course of the year 2000, five workshops were conducted by the Center for Global Security Research at the Lawrence Livermore National Laboratory on threats to international security in the 2015 to 2020 timeframe due to the global availability of advanced technology. These workshops focused on threats that are enabled by nuclear, missile, and space technology; military technology; information technology; bio technology; and geo systems technology. The participants included US national leaders and experts from the Department of Energy National Laboratories; the Department of Defense: Army, Navy, Air Force, Office of the Secretary of Defense, Defense Threat Reduction Agency, and Defense Advanced Research Projects Agency; the Department of State, NASA, Congressional technical staff, the intelligence community, universities and university study centers, think tanks, consultants on security issues, and private industry. For each workshop the process of analysis involved identification and prioritization of the participants' perceived most severe threat scenarios (worst nightmares), discussion of the technologies which enabled those threats, and ranking of the technologies' threat potentials. The threats ranged from local/regional to global, from intentional to unintended to natural, from merely economic to massively destructive, and from individual and group to state actions. We were not concerned in this exercise with defining responses to the threats, although our assessment of each threat's severity included consideration of the ease or difficulty with which it might be executed or countered. At the concluding review, we brought the various workshops' participants together, added senior participant/reviewers with broad experience and national responsibility, and discussed the workshop findings to determine what is most certain or uncertain, and what might be needed to resolve our uncertainties.

The market penetration of breeding and fusion systems, therefore, will be the next important milestones of nuclear energy development. On the other hand nuclear energy as well as the electric grid itself are good examples for the reconstruction of the non-electric energy market which is dominated by resource and environmental problems.

    An assessment of current and future emissions, air concentrations, and atmospheric deposition of mercury worldwide is presented on the basis of results obtained during the performance of the EU GMOS (Global Mercury Observation System) project. Emission estimates for mercury were prepared with the main goal of applying them in models to assess current (2013) and future (2035) air concentrations and atmospheric deposition of this contaminant. The combustion of fossil fuels (mainly coal) for energy and heat production in power plants and in industrial and residential boilers, as well as artisanal and small-scale gold mining, is one of the major anthropogenic sources of Hg emissions to the atmosphere at present. These sources account for about 37 and 25 % of the total anthropogenic Hg emissions globally, estimated to be about 2000 t. Emissions in Asian countries, particularly in China and India, dominate the total emissions of Hg. The current estimates of mercury emissions from natural processes (primary mercury emissions and re-emissions), including mercury depletion events, were estimated to be 5207 t year-1, which represents nearly 70 % of the global mercury emission budget. Oceans are the most important sources (36 %), followed by biomass burning (9 %). A comparison of the 2035 anthropogenic emissions estimated for three different scenarios with current anthropogenic emissions indicates a reduction of these emissions in 2035 up to 85 % for the best-case scenario. Two global chemical transport models (GLEMOS and ECHMERIT) have been used for the evaluation of future mercury pollution levels considering future emission scenarios. Projections of future changes in mercury deposition on a global scale simulated by these models for three anthropogenic emissions scenarios of 2035 indicate a decrease in up to 50 % deposition in the Northern Hemisphere and up to 35 % in Southern Hemisphere for the best-case scenario.

    During the year 2015 the Department of Applied Physics of the Faculty of Electrical Engineering and Computing, University of Zagreb conducted a public opinion survey entitled 'Energy - The Present and the Future' among student population of 1115 individuals. The tested population consisted of the University of Zagreb six faculties' students: the Faculty of Electrical Engineering and Computing, the Faculty of Food Technology and Biotechnology, the Faculty of Chemical Engineering and Technology, the Faculty of Mining, Geology and Petroleum Engineering, the Faculty of Science, and the Faculty of Humanities and Social Sciences. The questions in the survey covered several different energy issues, including the present and the future energy resources, the acceptability of different fuel type power plants, the environmental protection and global warming, the radioactivity, the radioactive waste issues, reliable information sources, and position of participants towards climate change issues, as well as European Union and Croatian goals set for the year 2020. The basic results of survey analysis for nuclear oriented questions, as well as the comparison of results of the current survey with the results of the similar surveys conducted in the academic years 2007/08, and 2012/2013, are reported in this paper. Participants generally express high level of formal environmental awareness. However, their choices and attitudes are in a contradiction to claimed eco-orientation, as well as to the scientific facts. The discrepancies are particularly noticeable in parts of the survey dealing with the nuclear energy and the nuclear power plants. The participants are also demonstrating lack of knowledge on nuclear issues especially regarding radioactive waste management, as well as economics and operational safety of nuclear power plants.

    The "Global Heritage Stone Resource" designation arose in 2007 as a suggested mechanism to enhance international recognition of famous dimension stones. There were also many aspects of dimension stone study that had no formal recognition in mainstream geology and which could be recognised in a formal geological sense via an internationally acceptable geological standard. Such a standard could also receive recognition by other professionals and the wider community. From the start, it was appreciated that active quarrying would an important aspect of the designation so a designation different to any other standard was needed. Also the project was linked to the long-established Commission C-10 Building Stone and Ornamental Rocks of the International Association of Engineering Geology and the Environment (IAEG C-10). Since 2007, the "Global Heritage Stone Resource" (GHSR) proposal has evolved in both in stature and purpose due to an increasing number of interested international correspondents that were actively sought via conference participation. The "English Stone Forum" in particular was pursuing similar aims and was quick to advise that English dimension stone types were being recognised as having international, national or regional importance. Furthermore the proposed designation was suggested as to having significant value in safeguarding designated stone types whilst also providing a potential mechanism in preventing heritage stone replacement by cheap substitutes. During development it also became apparent that stone types having practical applications such as roofing slates and millstones or even stone types utilised by prehistoric man can also be recognised by the new designation. The heritage importance of architects was also recognised. Most importantly an international network evolved, primarily including geologists, that now seems to be the largest international grouping of dimension stone professionals. This has assisted the project to affiliate with the

    Since the industrial revolution, the consumption of energy resources throughout the world has increased in geometrical progression, depleting the reserves of the fossil fuels including petroleum. It is predicted that the known reserves of the petroleum and the natural gas will be exhausted within 40 and 60 years, respectively. Massive consumption of energy resources has aggravated the quality of air and water, with the result that environmental pollution of the world has reached a critical stage Emission of green house gases such as carbon dioxide has caused global warming and climate change, endangering the sustainability of the life. Mainland China and East Asian countries pursuing rapid economic growth are expected to confront a shortage of energy in the near future, leading them to face difficulties in achieving expected economic growth

    The paper surveys the major challenges to stabilizing the atmospheric CO 2 concentration. Climate change, and policies to deal with it, is viewed as an energy problem. The energy problem stems from the fact that no combination of carbon-free energies is currently capable of displacing fossil fuels as the main sources of the world's base load energy requirements. The paper provides rough estimates of the amount of carbon-free energy required to stabilize climate, the potential contribution of 'conventional' carbon-free energies, the contribution of renewable energies, and the size of an 'advanced energy technology gap'. The findings indicate that stabilizing CO 2 concentration will require a long-term commitment to research, develop, and eventually deploy new energy sources and technologies including hydrogen. The paper suggests that the role of technology is what makes stabilizing CO 2 concentration economically feasible. In this respect energy technology and economics are complementary, with advances in the former requiring something more than a reliance on market-based instruments, such as carbon taxes and emission permits. The analysis has implications for the credibility of commitments to target climate change-related factors such as CO 2 emissions.(author)

    Global energy use will most likely increase to more than double by 2050, which is e.g. the medium value of the projection in the Intergovernmentals Panel on Climate Change (IPCC) Special Report on Emissions Scenarios (SRES). How to reconcile the projections with the current nuclear status? In its first fifty years, nuclear power has grown from 5 MWe of power production to an installed worldwide capacity of 360 GWe in 30 countries. Nuclear power provides about 16% of the total electricity in the world and is contributing to the reduction of the emission of greenhouse gases from the power sector. The SRES scenarios identify a gap between the current electricity generation capacity and the capacity requirements in 2050 of 360 GWe and 1 500 GWe. Three key factors will determine the future contribution of nuclear power: - improved economics, - national energy choice and supporting infrastructure as well as institutional arrangement, and - the degree to which advances are implemented in evolutionary and innovative reactor and fuel cycle technologies, to address safety, waste and proliferation concerns, as well as economic competitiveness. The economics of nuclear power are one main topic in industrial countries. A Japanese case study on energy security credit shows that nuclear power will eventually be a winner in the long term perspective due to amortisation and stable fuel prices. Nuclear power is also a part of nuclear technologies to address daunting challenges in the developing countries - hunger, disease, poverty, and shortage of drinking water and electricity. (orig.)

    The global warming challenge aims at stabilizing the concentrations of Green House Gas (GHG) in the atmosphere. Carbon dioxide is the most effective of the anthropogenic GHG and is essentially produced by consumption of fossil fuels. Electricity production is the dominant cause of CO 2 emissions. It is, therefore, crucial that the share of 'carbon less' electricity production techniques increases at a fast pace. This is the more so, that 'clean' electricity would be useful to displace 'dirty' techniques in other fields such as heat production and transportation. Here we examine the extent to which nuclear energy could be operational in providing 'clean' electricity. A nuclear intensive scenario is shown to give the possibility to divide CO 2 emissions by a factor of 2 worldwide, within 50 years. However, the corresponding sharp increase in nuclear power will put a heavy burden on uranium reserves and will necessitate the development of breeding reactors as soon as possible. A review of present and future reactors is given with special attention to the safety issues. The delicate question of nuclear fuel cycle is discussed concerning uranium reserves and management of used fuels. It is shown that dealing with nuclear wastes is more a socio-political problem than a technical one. The third difficult question associated with the development of nuclear energy is the proliferation risk. It is advocated that, while this is, indeed, a very important question, it is only weakly related to nuclear power development. Finally, the possibilities of nuclear fusion are discussed and it is asserted that, under no circumstances, could nuclear fusion give a significant contribution to the solution of the energy problem before 50 years, too late for dealing with the global warming challenge.

    We must begin now to plan to replace fossil fuels as a major energy source. Few energy sources are capable of supplying the vast amount of energy required. The only options that can play a major role are coal, hydro-electricity, and nuclear. The soft energy options are not reliable: we cannot control the blowing of the wind or the shining of the sun; biomass is susceptible to disease. If we were to become too dependent on these we would be surrendering our energy system to the vagaries of nature. A strong electrical system is a cornerstone of energy security. Surplus capacity is often criticized, but a shortfall in supply will cause industrial chaos. Nuclear power is based on a sustainable resource supply, uses a proven technology, is economically competitive, and causes minimal harm to human populations and the environment

    The connection between Soviet oil and energy resources, their efficient and timely utilization, and politico-military opportunities in the Persian Gulf region offer an inescapable link for analysis. Worsening trends in economic growth, factor productivity, social unrest, and energy production/distribution offset optimistic trends in Soviet military procurement and deployment. A conjunction of geologic, geographic, and systemic factors all point to a mid-1980s energy imbalance which in turn will pose hard questions for the Moscow leadership. 28 references.

    Reductions in the cost of producing wind energy are helping to make this renewable energy source competitive with conventional energy sources. The market for this type of energy in Italy, however, hasn't yet gained a foothold even though close examination of Italy's geomorphology reveals that this country is in fact endowed with many areas having good potential for wind power production. This paper discusses the measures to be taken to bolster wind energy commercialization efforts in Italy. It provides a brief assessment of the current state of wind power technology, national and international market trends, and the directions being taken by other national governments to promote wind turbine manufacturing industries and applications. The comparative analysis indicates that in order to have this energy source alternative taken seriously as an economically viable energy option in Italy, greater financial assistance should be given to local manufacturers involved in commercialization efforts. In addition, a suitable rate structure should be created favouring wind power by taking into account cost benefits afforded by this renewable energy source in terms of reduced air pollution, as well as, reduced national dependency on foreign energy imports

    A current debate on environmental sociology involves how the subdiscipline should conceptualise and investigate the environment and whether it should be prescriptive and deliver policy recommendations. Taking this debate as a point of departure this article discusses the current and future role of sociology in a globalised world. It discusses how environmental sociology in the US and Europe differ in their understandings of sociology’s contribution to the study of the environment. Particular stress is placed on how these two regions differ with respect to their use of the tradition of sociological thought, views on what constitutes the environment and ways of institutionalising environmental sociology as a sociological field. In conclusion, the question is raised of whether current versions of environmental sociology are appropriate for analysing a globalised world environment; or whether environmental sociology’s strong roots in European and US cultures make it less relevant when facing an increasingly globalised world. Finally, the article proposes some new rules for a global environmental sociology and describes some of their possible implications for the sociological study of climate change. PMID:25937642

  6. Global Energy Transitions and the Challenge of Climate Change

    International Nuclear Information System (INIS)

    Riahi, K.

    2008-01-01

    Global emissions of greenhouse-gases have increased markedly as a result of human activities since pre-industrial times. This increase in emissions has lead to unequivocal global warming, which is evident from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice, and rising global average sea level. Reducing the risk of irreversible climate impacts requires thus the mitigation of global GHG emissions aiming at the long-term stabilization of atmospheric GHG concentrations. Achieving this goal translates into the need of reducing emissions to virtually zero over long time-frames. Yet international agreement on a long-term climate policy target remains a distant prospect, due to both scientific uncertainty and political disagreement on the appropriate balance between mitigation costs and reduced risks of dangerous impacts. At the same time, growing emissions of greenhouse gases continue to increase the amount of climate change we are committed to over the long term. Over the next few decades, these growing emissions may make some potentially desirable long term goals unattainable. Recent analysis conducted at IIASA indicates the need of major energy transitions over the next few decades. For example, staying below the target suggested by the European Union of 2 C warming (with just a 50% likelihood) will require the massive deployment of zero-carbon energy by 2050, and a tippling of the contribution of zero-carbon energy globally to more than 60% by that time. Although there are large uncertainties with respect to the deployment of individual future technologies, there is strong evidence that no single mitigation measure alone would be sufficient for achieving the stabilization of GHG concentrations at low levels. A wide portfolio of technologies across all GHG-intensive sectors is needed for cost-effective emissions reductions. The bulk of these emissions reductions would need to come from the energy sector, with

    Drought can have large impacts on multiple sectors, including agriculture, water resources, ecosystems, transport, industry and tourism. In extreme cases, regional drought can lead to food insecurity and famine, and in intensive agricultural regions, extend to global economic impacts in a connected world. Recent droughts globally have been severe and costly but whether they are becoming more frequent and severe, and the attribution of this, is a key question. Observational evidence at large scales, such as satellite remote sensing are often subject to short-term records and inhomogeneities, and ground based data are sparse in many regions. Reliance on model output is also subject to error and simplifications in the model physics that can, for example, amplify the impact of global warming on drought. This presentation will show the observational and model evidence for changes in drought, with a focus on the interplay between precipitation and atmospheric evaporative demand and its impact on the terrestrial water cycle and drought. We discuss the fidelity of climate models to reproduce our best estimates of drought variability and its drivers historically, and the implications of this on uncertainties in future projections of drought from CMIP5 models, and how this has changed since CMIP3.

    From 1st January 2013, the Copernicus Global Land Service is operational, providing continuously to European, African and International users a set of biophysical variables describing the vegetation conditions, the energy budget at the continental surface and the water cycle over the whole globe at one kilometer resolution. These generic products can serve numerous applications such as agriculture and food security monitoring, weather forecast, climate change impact studies, water, forest and natural resources management. The Copernicus Global Land Service is built on the achievements of the BioPar component of the FP7 geoland2 project. Essential Climate Variables like the Leaf Area Index (LAI), the Fraction of PAR absorbed by the vegetation (FAPAR), the surface albedo, the Land Surface Temperature, the soil moisture, the burnt areas, the areas of water bodies, and additional vegetation indices, are generated every hour, every day or every 10 days on a reliable and automatic basis from Earth Observation satellite data. Beside this timely production, the available historical archives have been processed, using the same innovative algorithms, to get consistent time series as long as possible. As an example, more than 30 years of LAI and FAPAR relying on NOAA/AVHRR sensors (from 1981 to 2000) and SPOT/VGT sensors (from 1999 to the present) are now available. All products are accessible, free of charge and after registration, at the following address: http://www.geoland2.eu/core-mapping-services/biopar.html. Documentation describing the physical methodologies, the technical properties of products, and the results of validation exercises can also be downloaded. In view of service continuity, research and development are performed on two parallel ways. On one hand, the existing retrieval methodologies will be adapted to new input data sets (e.g. Proba-V and Sentinel-3 at 1km resolution) that will be used in replacement of current sensor (SPOT/VGT) which reached the end

    The Symposium was organized by the Energy Research Institute of the State Economic Commission of China, and the Lawrence Berkeley Laboratory and Johns Hopkins University from the United States. It was held at the Johns Hopkins University Nanjing Center in late June 1988. It was attended by about 15 Chinese and an equal number of US experts on various topics related to energy demand and supply. Each presenter is one of the best observers of the energy situation in their field. A Chinese and US speaker presented papers on each topic. In all, about 30 papers were presented over a period of two and one half days. Each paper was translated into English and Chinese. The Chinese papers provide an excellent overview of the emerging energy demand and supply situation in China and the obstacles the Chinese planners face in managing the expected increase in demand for energy. These are matched by papers that discuss the energy situation in the US and worldwide, and the implications of the changes in the world energy situation on both countries. The papers in Part 1 provide historical background and discuss future directions. The papers in Part 2 focus on the historical development of energy planning and policy in each country and the methodologies and tools used for projecting energy demand and supply. The papers in Part 3 examine the pattern of energy demand, the forces driving demand, and opportunities for energy conservation in each of the major sectors in China and the US. The papers in Part 4 deal with the outlook for global and Pacific region energy markets and the development of the oil and natural gas sector in China.

  15. Some comments on the future world energy

    International Nuclear Information System (INIS)

    Lemperiere, F.

    2011-06-01

    The key problem is the possibility to get mid century the energy necessary for the world development at acceptable cost and impacts with 70 or 80% of renewable energies (essentially solar, wind, hydro and biomass). In 2050 a population of 9 billion (7 in sunny countries) will have probably a gross product 3 or 4 times the present one with a reduced energy intensity; the need of energy may be the double of the present one. The Primary Energy is not an useful reference for most 2050 sources: for instance closing a thermal or nuclear plant supplying 1 TWh and generating 2 TWh more by wind, PV or hydraulics double the Final Energy when reducing the Primary Energy. Presently the Primary Energy is close to 150.000 TWh/year and the Final Energy utilisation to 100.000 TWh. But the present need of Final Energy is lower because many utilizations could use other sources reducing the relevant Final Energy: as examples using PV for cooking in Asia or Africa should divide by over 5 the relevant final energy and using electric cars could divide the Final Energy for transports by 3. The need of Final Energy in 2050 may thus be between 150.000 and 200.000 TWh/year. Anyway the final energy used from many sources will be limited, i.e. a total probably between 60 and 90.000 TWh/year, much under needs of 150.000 to 200.000 TWh/year. There is thus a great uncertainly but it is very likely that the gap will be mid century in the range of 100.000 TWh/year, to be met by coal, wind or solar, essentially through electricity. Electricity will be close to 100.000 TWh/year, with 20.000 from hydro, nuclear, oil and gas and the balance: 80.000 from coal, wind and solar. It is possible to get quite all from wind and solar under 4 conditions: - Coal resources could supply up to 50.000 TWh/year along most of the century at a direct cost lower (before 2040) than solar power by few cents per KWh (at least before 2030 or 2040), i.e. a saving which may be possibly 0,5 or 1% of the gross product.

    An educated guess is made of the energy demand in developing countries well into the next century in order to estimate the possible role of new and renewable sources in meeting this demand. The world is roughly divided into industrialized (IND) and developing (LDC) countries. A plot of energy demand in both parts shows a possible structure of mixed energy to meet LDC demand, but there is a gap between demand and supply from conventional sources in LDCs that has to be met by new and renewable sources. When the demand for specific energy forms is projected, as much as two thirds of the final energy needed from new sources should be based on centralized-electricity and liquid-fuels technologies. Solar and geothermal energy must compete with nuclear and thermonuclear breeders, while solar prospects for chemical fuel supply in LDCs lacking adequate coal reserves seems promising. There is a large gap in research and development (R and D) spending on new energy between the two parts, which means that LDCs will have inappropriate technology at a high price. An increase in R and D spending on a regional basis should target funds to appropriate options. 6 references, 7 figures.

    This document presented the key findings of the Nuclear Energy Futures project that was initiated in May 2006 to consider global governance of nuclear energy. The five-point action plan presented in this document included: (1) nuclear safety whereby all nuclear states are committed to and capable of implementing the highest nuclear safety standards, (2) nuclear security whereby all nuclear material and facilities are secure from unauthorized access or terrorist seizure or attack, (3) nuclear nonproliferation whereby a nuclear revival does not contribute to the proliferation of nuclear weapons, (4) the re-enforcement of the International Atomic Energy Agency's centrality through increased funding, modernization and reform, and (5) stakeholder involvement whereby all partners, especially industry, participate in judiciously managing a nuclear revival. This document suggested that despite some powerful drivers, the revival of nuclear energy faces too many barriers compared to other means of electricity production. These barriers include high costs; fewer subsidies; too slow for meeting the threat of climate change; inadequate power grids; unresolved nuclear waste issue; and fears about safety, security and nuclear weapons.

    During the academic year 2007/08 the Department of Applied Physics of the Faculty of Electrical Engineering and Computing conducted a public opinion survey entitled 'Energy - The Present and the Future' among student population of 1439 individuals age 18-20. The tested population consisted of the University of Zagreb nine faculties' students: the Faculty of Electrical Engineering and Computing - 367 students, the Faculty of Food Technology and Biotechnology - 149 students, the Faculty of Chemical Engineering and Technology - 118 students, the Faculty of Civil Engineering - 102 students, the Faculty of Philosophy - 100 students, the Faculty of Science - 50 students, the Medical School - 217 students, the School of Dental Medicine - 108 students, and the Faculty of Economics and Business - 228 students. The questions in the survey covered several different energy issues, including the present and the future energy resources, the acceptability of different fuel type power plants, the environmental protection and global warming, the radioactivity, the waste issues, as well as reliable information sources. The basic results of survey analysis for nuclear oriented questions are reported in this paper. Although participants expressed high level of formal environmental awareness, their choices and attitudes are in a contradiction to claimed eco-orientation, as well as to the scientific facts. The discrepancies are particularly noticeable in parts of the survey dealing with the nuclear energy and the nuclear power plants. The radioactive waste management, proved to be a potential stumbling-stone for the entire nuclear program. The participants are demonstrating deep lack of knowledge which results in the radioactive waste management becoming the main source of fear from the nuclear technology in general. A very disturbing attitude is a belief that the nuclear energy is non-economic, environmentally unacceptable and operationally unsafe source of energy. Such an attitude

    The relationship between gross national product and energy use is studied for a number of countries and for the United States is particular. The relationship between income inequalities and energy use is also examined. The similarity between income inequality in an economic system and temperature differences in a thermodynamic system is noted. An economic chain analysis is used to derive income inequality distributions for a less-developed country and for a very-developed country. Finally the role of expensive but domestic-origin energy is examined. (U.K.)

    The biofuels include bioethanol, biobutanol, biodiesel, vegetable oils, biomethanol, pyrolysis oils, biogas, and biohydrogen. There are two global biomass based liquid transportation fuels that might replace gasoline and diesel fuel. These are bioethanol and biodiesel. World production of biofuel was about 68 billion L in 2007. The primary feedstocks of bioethanol are sugarcane and corn. Bioethanol is a gasoline additive/substitute. Bioethanol is by far the most widely used biofuel for transportation worldwide. About 60% of global bioethanol production comes from sugarcane and 40% from other crops. Biodiesel refers to a diesel-equivalent mono alkyl ester based oxygenated fuel. Biodiesel production using inedible vegetable oil, waste oil and grease has become more attractive recently. The economic performance of a biodiesel plant can be determined once certain factors are identified, such as plant capacity, process technology, raw material cost and chemical costs. The central policy of biofuel concerns job creation, greater efficiency in the general business environment, and protection of the environment.

    We address the issues of future resource unsustainability, energy demand uncertainty and supply unpredictability. Inexorably growing global energy demand increases the costs of energy sources, and raises concerns about security of energy supply and environmental emissions of carbon dioxide and other greenhouse gases (GHGs). Taking the viewpoint of developing a sustainable global fuel cycle, we propose alternate paths outside the present rather traditional thinking. Nevertheless, they still represent existing and known technology opportunities that may run counter to many current national positions, and today's commercial and technical interests, while still presenting very large opportunities.

    In the 1970s, nuclear energy was expected to quickly become the dominant generator of electrical power. Its fuel costs are remarkably low because a million times more energy is released per unit weight by fission than by combustion. But its capital costs have proven to be high. Safety requires redundant cooling and control systems, massive leak-tight containment structures, very conservative seismic design and extremely stringent quality control.

    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

    Globalization is a widely-used term that can be defined in a number of different ways. When used in an economic context, it refers to the reduction and removal of barriers between national borders in order to facilitate the flow of goods, capital, services and labour. Globalization is not a new phenomenon. Today the concept of globalization can be extended to include global exposure to infectious diseases, which is becoming more apparent. The aim of this article is to examine the influence of globalization on the outbreak and spread of infections in the world.

    The world is facing major challenges in providing energy services to meet the future needs of the developed world and the growing needs of developing countries. These challenges are exacerbated by the need to provide energy services with due respect to economic growth, sustainability and security of supply. Today, the world's energy system is based mainly on oil, gas and coal, which together supply around 80% of our primary energy. Only around 0.5% of primary energy comes from renewable sources such as wind, solar and geothermal. Despite the rapid development of new energy technologies, the world will continue to depend on fossil fuels for several decades to come - and global primary energy demand is forecasted to grow by 60% between 2002 and 2030. The expected post Kyoto targets call for significant CO{sub 2} reductions, increasing the demand to decouple the energy and transport systems from fossil fuels. There is a strong need for closer links between electricity, heat and other energy carriers, including links to the transport sector. On a national scale Denmark has three main characteristics. Firstly, it has a diverse and distributed energy system based on the power grid, the district heating grid and the natural gas grid. Secondly, renewable energy, especially wind power, plays an increasingly important role in the Danish energy system. Thirdly, Denmark's geographical location allows it to act as a buffer between the energy systems of the European continent and the Nordic countries. Energy systems can be made more robust by decentralising both power generation and control. Distributed generation (DG) is characterised by a variety of energy production technologies integrated into the electricity supply system, and the ability of different segments of the grid to operate autonomously. The use of a more distributed power generation system would be an important element in the protection of the consumers against power interruptions and blackouts, whether

It contributes to the clarification of terminology referring to the global aspects of startups, summarizes insights from previous literature focusing on global startups, and further substantiates the articulation of the need for considering the lean global startup as a new type of firm. The main message is that the lessons learned from the emergence of lean startup entrepreneurship offer a basis for promoting a similar lean phase in technology-based global startup research and practice. The analysis should benefit both researchers and practitioners in technology entrepreneurship, international entrepreneurship, and global innovation management.

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

    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.

    Full Text Available Identifying which species are at greatest risk, what makes them vulnerable, and where they are distributed are central goals for conservation science. While knowledge of which factors influence extinction risk is increasingly available for some taxonomic groups, a deeper understanding of extinction correlates and the geography of risk remains lacking. Here, we develop a predictive random forest model using both geospatial and mammalian species' trait data to uncover the statistical and geographic distributions of extinction correlates. We also explore how this geography of risk may change under a rapidly warming climate. We found distinctive macroecological relationships between species-level risk and extinction correlates, including the intrinsic biological traits of geographic range size, body size and taxonomy, and extrinsic geographic settings such as seasonality, habitat type, land use and human population density. Each extinction correlate exhibited ranges of values that were especially associated with risk, and the importance of different risk factors was not geographically uniform across the globe. We also found that about 10% of mammals not currently recognized as at-risk have biological traits and occur in environments that predispose them towards extinction. Southeast Asia had the most actually and potentially threatened species, underscoring the urgent need for conservation in this region. Additionally, nearly 40% of currently threatened species were predicted to experience rapid climate change at 0.5 km/year or more. Biological and environmental correlates of mammalian extinction risk exhibit distinct statistical and geographic distributions. These results provide insight into species-level patterns and processes underlying geographic variation in extinction risk. They also offer guidance for future conservation research focused on specific geographic regions, or evaluating the degree to which species-level patterns mirror spatial

    The analysis of different global energy scenarios in part I of the report confirms that the exploitation of energy efficiency potentials and the use of renewable energies play a key role in reaching global CO2 reduction targets. An assessment on the basis of a broad literature research in part II shows that the technical potentials of renewable energy technologies are a multiple of today's global final energy consumption. The analysis of cost estimates for renewable electricity generation technologies and even long term cost projections across the key studies in part III demonstrates that assumptions are in reasonable agreement. In part IV it is shown that by implementing technical potentials for energy efficiency improvements in demand and supply sectors by 2050 can be limited to 48% of primary energy supply in IEA's ''Energy Technology Perspectives'' baseline scenario. It was found that a large potential for cost-effective measures exists, equivalent to around 55-60% of energy savings of all included efficiency measures (part V). The results of the analysis on behavioural changes in part VI show that behavioural dimensions are not sufficiently included in energy scenarios. Accordingly major research challenges are revealed.

  20. World Energy Balance Outlook and OPEC Production Capacity: Implications for Global Oil Security

    Directory of Open Access Journals (Sweden)

    Azadeh M. Rouhani

    2012-07-01

    Full Text Available The imbalance between energy resource availability, demand, and production capacity, coupled with inherent economic and environmental uncertainties make strategic energy resources planning, management, and decision-making a challenging process. In this paper, a descriptive approach has been taken to synthesize the world’s energy portfolio and the global energy balance outlook in order to provide insights into the role of Organization of Petroleum Exporting Countries (OPEC in maintaining “stability” and “balance” of the world’s energy market. This synthesis illustrates that in the absence of stringent policies, i.e., if historical trends of the global energy production and consumption hold into the future, it is unlikely that non-conventional liquid fuels and renewable energy sources will play a dominant role in meeting global energy demand by 2030. This should be a source of major global concern as the world may be unprepared for an ultimate shift to other energy sources when the imminent peak oil production is reached. OPEC’s potential to impact the supply and price of oil could enable this organization to act as a facilitator or a barrier for energy transition policies, and to play a key role in the global energy security through cooperative or non-cooperative strategies. It is argued that, as the global energy portfolio becomes more balanced in the long run, OPEC may change its typical high oil price strategies to drive the market prices to lower equilibria, making alternative energy sources less competitive. Alternatively, OPEC can contribute to a cooperative portfolio management approach to help mitigate the gradually emerging energy crisis and global warming, facilitating a less turbulent energy transition path while there is time.

    We are in charge of our energy future and thus of the future itself. Energy decisions in the past were made on a too narrow and short-term basis, and we can daily clearly observe their inadequacy. The policy's quality does not correspond to the significance of the problem. A greater approximation leads to a consequent policy of the development of energy alternatives, of which some considerably deviate from those which would result at a closer look. This lecture deals with two aspects of the problem, both concern the future of nuclear energy. The first aspect treats extensively the energy possibilities available to the world in the future; the second deals more with the problem of the acceptibility of nuclear energy, reprocessing of nuclear fuels, the relationship to atomic armament and the thus involved problems.

    In April this year, the Department of Industry, Science and Resources published a report outlining the dilemmas facing Japan's energy industry in the post-Kyoto environment with particular reference to the effect it would have on Australia's fuel exports. The following article is based on information in that report. In summary, the extent to which the Japanese government's current climate change response policy (the long term energy forecast) is realised will depend on a complex interaction of competing considerations: 1. whether, in the event of US non ratification, the government maintains its Kyoto commitment or opts for a partial step back from its 8% commitment (and the extent of that draw back); 2. in the event that it does maintain its Kyoto commitment: a) the extent to which it takes advantage of the flexible mechanism provisions to ease the abatement burden on the energy system; b) the level of success in securing additional nuclear power stations and higher load ratios from nuclear power; c) the degree to which renewable and recycling energy sources can be brought on line; d) the extent to which the Japanese people are willing to meet the costs of switching to new technology and changing lifestyles to conserve energy; e) the timing of new initiatives such as emissions trading; the extent to which Japanese industry is able to achieve very strict energy conservation targets; f) the extent to which Japan's economic recovery leads to increased electricity demand as well as g) the extent to which electricity deregulation reduces prices and promotes increased consumption

The scenarios are distinguished principally by divergent futures with respect to two highly influential factors driving change in global wood-product markets, whose future development is unpredictable. These so-called critical uncertainties were found to be degrees to which: (i current patterns of globalization will continue, or be replaced by regionalism, and (ii concern about the environment, particularly climate change, related policy initiatives and customer preferences, will materialize. The overall future of the Swedish solid wood-product industry looks bright, irrespective of which of the four possible futures occurs, provided it accommodates the expected growth in demand for factory-made, energy-efficient construction components. The prospects for the pulp and paper industry in Sweden appear more ambiguous. Globalization is increasingly shifting production and consumption to the Southern hemisphere, adversely affecting employment and forest owners in Sweden. Further, technical progress in information and communication technology (ICT is expected to lead to drastic reductions in demand for newsprint and printing paper. Chemical pulp producers may profit from a growing bio-energy industry, since they could manufacture new, high-value products in integrated bio-refineries. Mechanical pulp producers cannot do this, however, and might suffer from higher prices for raw materials and electricity.

    In the framework of a sustainable development with a reduction of the greenhouse gases emissions, the hydrogen seems a good solution because its combustion produces only water. From the today hydrogen industrial market, the authors examine the technological challenges and stakes of the hydrogen-energy. They detail the hydrogen production, distribution and storage and compare with the petrol and the natural gas. Then they explain the fuel cells specificity and realize a classification of the energy efficiency of many associations production-storage-distribution-use. a scenario of transition is proposed.

    After briefly reviewing trends in energy demand, supply and efficiency, I will focus on the potential and outlook for the major low carbon energy sources - in order of decreasing current importance: bioenergy, hydro, nuclear, wind and solar. Together, they are sufficiently abundant to replace fossil fuels, which would presumably happen if they were economically competitive. I will discuss how close low carbon sources are to being competitive (which in the case of wind and solar depends on the cost of integrating large-scale intermittent supply), and the tech...

    The use of energy in the industrial sectors of nations with both industrialized and developing economies will continue to be, a major source of greenhouse gas (GHG) emissions, particularly carbon dioxide. The patterns of industrial-sector energy use--energy provided primarily by the combustion of fossil fuels-have shifted both within the between countries in recent decades. Projections of future energy use and carbon-dioxide (CO{sub 2}) emissions suggest continued shifts in these patterns, as industrial production in developed countries stabilizes and declines, while industrial output in the developing world continues to expand. This expansion of industrial-sector activity and CO{sub 2} emissions in developing countries presents both a challenge and an opportunity. To seize this opportunity and contribute to international efforts to mitigate global climate change, the United National Industrial Development Organization (UNIDO) recently initiated a two-phase effort to help improve the efficiency of energy-intensive industries (iron and steel, chemicals, refining, paper and pulp, and cement) in developing countries. As part of the Phase I, the authors reviewed industrial sector scenarios and to initiated development of a software-based toolkit for identifying and assessing GHG mitigating technologies. This toolkit, called IDENTIFY, is comprised of a technology inventory and a companion economic analysis tool. In addition, UNIDO commissioned institutions in India, South Africa, and Argentina to review energy use patterns and savings opportunities in selected industries across nine developing countries, and contribute to the development of the IDENTIFY toolkit. UNIDO is now preparing to launch Phase 2, which will focus on full development and dissemination of the IDENTIFY toolkit through seminars and case studies around the world. This paper describes Phase 1 of the UNIDO project.

    Full Text Available This paper results from discussions triggered during the "Stream Ecology Symposium" that took place at the XIII Congress of the Brazilian Society of Limnology in September of 2011 in Natal, Brazil. Based on our experiences, we have raised several questions regarding ecological studies of headwater streams facing threats under global-changes and proposed numerous subjects to be addressed in future studies in Brazil. These studies deal with the necessity of knowing species biology and the elaboration of models to assess changes (which implies the availability of time-series or large-scale data sets; the ecology of riparian zones and the interchange of materials and energy across the land-water boundaries; forest conversions and standardized sampling strategies and data treatment to assess global change.

    Europe is in a very difficult situation regarding the future of energy supply because it is highly dependent on import of oil and natural gas. In addition, because of environmental pollution, global climate changes, ?nite World reserves of fossil fuels and geo-political implications of distribution of those reserves, such an energy system is not sustainable. The need for inevitable changes in energy supply is becoming more and more obvious. This includes not only a change of the energy sources, but also in energy carriers and technologies for their conversion into useful forms of energy, as well as a change in the ways energy is used today. Based on present knowledge, the only energy sources that satisfy the sustainability requirements are the renewable energy sources - direct solar insolation and its consequences (wind, hydro, biomass). As the renewable energy sources cannot be utilized directly in most of applications there is a need for such energy carriers which can be produced from renewable energy sources and which can satisfy all the energy needs at the end use, again satisfying the sustainability requirements. Electricity is one of such energy carrier which may be used in most but not in all applications. There is a need for other energy carriers in the form of fuels which can be stored and used, for example, in the transportation sector. This is a role that hydrogen can fulfill in a future energy system - hydrogen satisfies the conditions of sustainability, can be produced from renewable energy sources and together with electricity can satisfy all energy needs. Although the role of hydrogen in a future energy system can be envisioned with some certainty, the problem is the transition, i.e. switching from the present energy system based on fossil fuels to the future energy system based on renewable energy sources. Of course, such transition cannot happen overnight, but the question is where and how to start and at which pace to proceed. Insistence on short

    Two hundred years ago, much of humanity's energy came from burning wood. As energy needs outstripped supplies, we began to burn fossil fuels. This transition allowed our civilization to modernize rapidly, but it came with heavy costs including climate change. Today, scientists and engineers are taking another look at biofuels as a source of energy to fuel our ever-increasing consumption.

    This paper will address how the energy needs are covered today and will also present scenarios for tomorrow. Better technologies can stretch the limited energy resources, reduce the ecological impact and improve the security of supply for many countries depending on energy imports. Many of these efficient technologies are available today but need time and often financial support to penetrate the market, when not cost competitive. The other important lever is increasing the share of renewable and nuclear energy. (orig.)
