The case for nuclear electric power

Summary What role should the United States play in the energy economy of the world? Do we want to be uninvolved? Do we sit back and let the other industrial countries supply the rest of the world with nuclear power? Already, the world with four billion people and too high a growth rate is headed for trouble that could engulf us all. Four of five decades from now, when the population will have doubled to eight billion, the low sophistication level of today's energy users will very likely have run the total energy use very high. We in the United States will not only have our own energy problems; there will be an imperative need for a world energy policy, and we should be part of the negotiation. The United States will have to be more than self-sufficient. Power from uranium and thorium will expectably be our backbone. both at home and abroad. Among other things, Americans cannot afford to have profligate worldwide use of fossil fuel, with the expected movement of good crop weather northward, away from the best food-producing areas. American agriculture might be hit the hardest. Problems like these are world problems, and they just won't go away. We are part of them. Is it not to our own interest to have our own energy situation under control, so we can help shape the global outcome?

Factors influencing voting by the united states congress on the national energy act

A myriad of factors, both economic and political, influenced the voting by members of the United States Congress on the 1978 National Energy Act. Determinant factors considered in our analysis included the percentage of residents in the Congressman's district residing in the central city or on farms; the percentage of residents who belong to labor unions; the average level of education of the residents; oil, coal, and natural gas production in the state relative to total domestic production. The results, determined by means of logit analysis, indicate that the impact on low-income energy consumers, the effect on overall employment, the impact on farmers, and the benefits to energy interests, as well as ideology and the subjective perception that the need exists to do something about the energy situation in the United States, were all important explanatory factors.The author is an economist with the United States Department of Energy.

Energy efficiency: The best immediate option for a secure, clean, healthy future

The imperatives for reducing the world's dependence on fossil and nuclear fuels have multiplied manifold in recent years with the advent of worldwide terrorism. These new dangers come in addition to the imperatives of addressing the dire consequences of global warming and devastating pollution that accompany the use of these fossil fuels. Reducing dependence on these unsafe and unreliable energy resources should be a top global priority. Implementation of proven energy efficiency technologies offers the world the fastest, safest, most economic and most environmentally benign way to alleviate these threats. This article outlines available efficiency measures, their economic advantages and means by which they may be and have been implemented. While examples of efficiency applications from both developed and developing countries are given, the article relies heavily on experience with energy efficiency in the United States, where data on efficiency is particularly abundant.     

Renewable energy: Biomass power and biofuels as alternative sustainable energy sources

This article describes biomass fuels as renewable and sustainable energy resources in Minnesota as well as across the United States. This country has long benefited from surplus supplies of diverse energy resources, while our dependency on foreign petroleum supplies and domestic coal reserves has only recently prompted Congress to recognize the importance of renewable and alternative fuels such as biomass energy. Our further utilization of biomass power and biofuels can be an important step in altering our dependency on both coal and petroleum while simultaneously reducing carbon dioxide emissions. © 1998 John Wiley & Sons, Inc.     

美国环境应急管理制度简析

美国作为工业发达国家,经过百余年的发展,建立了世界领先的环境应急管理制度。自2005年松花江水污染事件爆发至今,我国的环境应急管理需求迫切,管理水平也在飞速提升。对美国的环境应急管理制度的分析能为我国环境应急管理工作提供借鉴。首先,美国设立了以宪法为根基,以应急管理法律法规为主要枝干,以针对突发性环境事件的专门性立法为具体内容的管理体系。其次,美国建立了包括总统、联邦应急管理署、美国国家环境保护局,以及州、县和地方政府中的管理机构在内的多层级应急管理系统。再次,美国基于国家应急系统(NRS)及其核心国家应急计划(NCP),为环境应急响应工作制定了清晰的工作流程。此外,美国还设立了超级基金,有助于有效解决应对环境突发事件的资金来源问题。2014年1月,美国西弗吉尼亚州发生埃尔克河化学品泄漏污染水源事件,通过将该污染事故作为案例进行分析,本文详细梳理了美国各层级政府对该污染事故的应急响应处理流程,体现出其具有的流程规范、分工清晰、属地处理、联邦支持等特点。     

Alternative energy: Environmental and economic factors associated with renewable energy and creating new integrated energy management systems

At best, the future of alternative and renewable energy remains uncertain. Our dependency on fossil fuels is already depleting world supplies of coal and petroleum while increasing greenhouse gas emissions. Most assuredly, the ability of alternative energy, described in this article as biomass, hydrogen, wind, solar, and geothermal power, to compete and even integrate with fossil fuels will depend on several important variables: First, developing, as well as developed, countries must be willing to direct long-term public and private funding towards innovative energy technologies by increasing research and promoting public education. Secondly, the “bottom line” economics associated with alternative energy technology must clearly show a positive cost/benefit ratio. Revenues and not deficits are paramount to the sustainability of alternative energy. Lastly, many experts argue for the environmental benefits of alternative energy by way of carbon reductions. The 1997 Kyoto Global Warming Treaty requires the United States in particular to reduce carbon dioxide emissions from fossil fuel burning by 7 percent below 1990 levels. While many experts argue that reactions to global warming and the alternative energy benefits anticipated because of them are fiscally irresponsible and not worth the billions of tax dollars intended, we can be assured that a business-as-usual attitude will continue without increased government and public support.© 1999 John Wiley & Sons, Inc.     

Acid rain in Asia

Acid rain has been an issue of great concern in North America and Europe during the past several decades. However, due to the passage of a number of recent regulations, most notably the Clean Air Act in the United States in 1990, there is an emerging perception that the problem in these Western nations is nearing solution. The situation in the developing world, particularly in Asia, is much bleaker. Given the policies of many Asian nations to achieve levels of development comparable with the industrialized world—which necessitate a significant expansion of energy consumption (most derived from indigenous coal reserves)—the potential for the formation of, and damage from, acid deposition in these developing countries is very high. This article delineates and assesses the emissions patterns, meteorology, physical geology, and biological and cultural resources present in various Asian nations. Based on this analysis and the risk factors to acidification, it is concluded that a number of areas in Asia are currently vulnerable to acid rain. These regions include Japan, North and South Korea, southern China, and the mountainous portions of Southeast Asia and southwestern India. Furthermore, with accelerated development (and its attendant increase in energy use and production of emissions of acid deposition precursors) in many nations of Asia, it is likely that other regions will also be affected by acidification in the near future. Based on the results of this overview, it is clear that acid deposition has significant potential to impact the Asian region. However, empirical evidence is urgently needed to confirm this and to provide early warning of increases in the magnitude and spread of acid deposition and its effects throughout this part of the world.     

Feedlot Biomass Co-firing: A Renewable Energy Alternative for Coal-fired Utilities

The swiftly growing feedlot industry in the United States upshots in the production of manure from one or more animal species in excess of what can safely be applied to farmland, in accordance with nutrient management plans. Disposal of the vast quantity of manure produced as a by-product of the cattle feeding industry is one of the major operating tasks of the industry. Aside from the traditional means of disposal as fertilizer, an alternative and attractive way of overcoming this threat is to develop processes that make use of manure as an energy resource. In the present study, the feasibility of using manure as a fuel in existing coal fired power plants is considered and appropriately termed Feedlot Biomass (FB). The technology of co-firing coal: feedlot biomass facilitates an environment friendly utilization of animal waste for the production of valuable power/steam concurrently addressing the renewable energy, groundwater contamination, and greenhouse gas concerns. Co-firing tests were performed at the Texas A&M University 30 kW_t (100,000 Btu/h) laboratory-scale facility. The trials revealed the enhanced combustion of the blends. The NO emissions were less for the blend even with higher nitrogen content of FB, as compared to coal.     

Wind‐Powered Desalination: An Estimate of Saline Groundwater in the United States1

James Androwski, Abraham Springer, Thomas Acker, and Mark Manone, 2011. Wind‐Powered Desalination: An Estimate of Saline Groundwater in the United States. Journal of the American Water Resources Association (JAWRA) 47(1):93‐102. DOI: 10.1111/j.1752‐1688.2010.00493.x Abstract: Increasing scarcity of freshwater resources in many regions of the world is leading water resource managers to consider desalination as a potential alternative to traditional freshwater supplies. Desalination technologies are energy intensive and expensive to implement making desalination using renewable energy resources a potentially attractive option. Unfortunately, saline groundwater resources are not well characterized for many regions hindering consideration of such technologies. In this assessment, we estimate the saline groundwater resources of the principal aquifers of the United States using a geographic information system and correlate these resources to wind resources potentially sufficient to supply the energy demand of desalination equipment. We estimate that 3.1 × 10¹⁴ m³ saline groundwater, total volume, are contained in 28 of the country’s principal aquifers known to contain saline groundwater. Of this volume, 1.4 × 10¹⁴ m³ saline groundwater are co‐located with wind resources sufficient for electrical generation to desalinate groundwater.     

Electricity supplies for the primary aluminium industry

The historical relationship between aluminium smelting and hydroelectric development is examined. Data on hydroelectric schemes presently planned or under construction are used to project the quantities of aluminium which could be produced using hydroelectric power by the year 2000. Projections of aluminium demand are made and these are compared with the projections of hydrobased aluminium supply. It is concluded that the majority of the world aluminium capacity which will be installed up to the end of this century will have to rely on non-hydroelectric power, based on coal or nuclear energy. The sensitivity of the projections to the assumptions is tested and the conclusions are found to be robust.

Health and safety implications of alternative energy technologies. III. Fossil energy

This paper reviews both innovative fossil energy sources (tar sands, oil shale, and unconventional natural gas), and more established technologies that are being considered as suppliers of gaseous and liquid fuels (that is, coal gasification and liquefaction). Potential health and safety issues related to the technologies are discussed, although the absence of commercial-scale facilities in the United States restricts the discussion to health effects information derived from related processes. The available epidemiological and carcinogenic studies give cause for concern. The study of the health and environmental impacts of the emerging fossil fuel technologies will be important for quantification of adverse effects and rectification of problems before commitment to large-scale commercialization occurs.Operated by Union Carbide Corporation under contract W-7405-eng-26 with the U.S. Department of Energy.     

Coal Combustion Product: Nonhazardous Material for Mine Fill

As is the case in many other countries around the world, India's main source of electricity is coal‐fired power plants. In addition to providing energy, the burning of coal also results in large amounts of coal combustion products (CCP), the incombustible material, such as fly ash, left after the coal is burned. These materials are produced in large volume, and if they are not managed or utilized properly, they can pose a danger to the environment. This article discusses the uses of CCP, with a special emphasis on fly ash, and the role that it is currently playing and can continue to play as a mine filler for India's depleted opencast and underground coal mines.     

From the erosion of crude oil prices to reorganization of the oil industry

Comparison of data on world energy consumption for 1986, 1987 and 1988 indicates that the consumption of all forms of energy increased during the period, but the demand for oil increased at a lesser rate than that of other energy sources. Although the pattern varies between countries, the overall picture is one of increased use of natural gas, coal, nuclear and hydropower as an energy source. Part of the reason for the low growth in oil demand is the oil conservation measures put in place when oil was much more expensive, but may partly be due to the scepticism of many people about the future movement of oil prices. The likely continuation of a low growth market for oil has led some oil exporting countries to move downstream in an effort to secure a dependable market for their oil and oil products.     

WATER CONSTRAINTS ON EMERGING ENERGY PRODUCTION1

ABSTRACT: A comprehensive nationwide recognizance-level assessment of water needs for energy development over the 1985 to 2000 time frame and options for overcoming any actual or potential water supply problems are summarized. Water requirements for energy production and other uses are totaled for each geographic region of the United States and compared with available stream flow to identify regions with potentially inadequate water supplies to meet expanding energy needs. Water quality impacts and water-related institutional factors affecting energy development are also considered. It is concluded that, if proper planning measures are not initiated, water demands for energy production will not be satisfied by the year 2000, particularly in those areas with known fossil energy resources. No unmanageable water quality problems are foreseen, and water-related institutional factors will primarily delay rather than exclud energy development.     

Comparative Analysis of New Zealand and US Approaches for Agricultural Nonpoint Source Pollution Management

The role of the central government in New Zealand is generally limited to research and policy development, and regional councils are responsible for most monitoring and management of the problem. The role of the federal government in the United States includes research and monitoring, policy development, and regulation. States also have a significant management role. Both countries rely on voluntary approaches for NPS pollution management. Very few national water quality standards exist in New Zealand, whereas standards are widely used in the United States. Loading estimates and modeling are often used in the United States, but not in New Zealand. A wide range of best management practices (BMPs) are used in the United States, including buffer strips and constructed/engineered wetlands. Buffer strips and riparian management have been emphasized and used widely in New Zealand. Many approaches are common to both countries, but management of the problem has only been partly successful. The primary barriers are the inadequacy of the voluntary approach and the lack of scientific tools that are useful to decision-makers. More work needs to be performed on the evaluation of approaches developed in both countries that could be applied in the other countries. In addition, more cooperation and information/technology transfer between the two countries should be encouraged in the future.

Energy Conservation in Rapid-Growth Economies of Asia

Energy demand, including demand for petroleum, is expected to increase at a faster rate in the rapidly-developing nations of East and Southeast Asia than elsewhere in the world through the turn of the century. In the aggregate, the countries of this region are heavily dependent on imported oil, coal and natural gas. Rapid industrialization, electrification and increased consumer demand for energy-consuming durable goods and housing underlie the expected strong growth in energy consumption. Substantial scope for greater economy in energy-use exists in the industrial and transport sectors but effects in these areas will require effective management and institutional support in addition to getting prices right. In the context of balance of payments and external debt considerations, and the continued growth of energy consumption in East and Southeast Asia, improving energy conservation will be of great importance in lessening the likelihood that future economic development will be constrained by energy problems.
