Description: One of the important aspects of America's painful adjustment to energy realities since 1973 has been an overwhelming effort to look carefully at how we use energy. Much to our surprise there was tremendous slack in energy use at home even before the Oil Embargo, slack that could have been eliminated profitably. One suggestion that there was waste in our economy came from careful inspection of energy use elsewhere. But early discussion of energy use in other lands has been marred by many distortions and misunderstandings, not only on the part of those who tend to doubt the potential for energy conservation but even among conservation's strongest supporters. This misunderstanding arises from comparisons of energy use and gross national product, two quantities that have charmed correlators and energy statisticians for decades. Though serious work cannot be based upon relationships between two such aggregated quantities, it is useful to review some of the popular myths surrounding energy comparisons among countries.

Description: This paper provides an assessment of broad trends in progress on assessment and implementation of adaptation to climate change in “developed countries”, defined here as being Member states of the OECD and/or Parties listed under Annex I of the United Nations Framework Convention on Climate Change (UNFCCC). Primary inputs to this analysis are the National Communications (NCs) by these countries to the UNFCCC. NCs follow a standardised reporting format which facilitates cross-national comparison. They also reflect “whole government” perspectives. At the same time, however, the coverage of particular issues within these documents need not be comprehensive, nor might it necessarily reflect policy priorities on the ground. Therefore, this paper also examines other policies and projects which highlight progress on implementing adaptation, but which have not been reflected in the NCs.

Integrating hazardous waste management into a multimedia pollution prevention paradigm. A protoype regulatory program for petroleum refinesments

Description: An emerging trend in environmental regulatory management promises enhanced environmental protection and more flexibility for regulated entities. This trend reflects three concepts. First, regulations designed to reduce one type of environmental pollution (e.g., air pollution) should not increase other types of pollution (e.g. hazardous waste). Second, pollution prevention is an important alternative to end-of-pipe control requirements. Third, offering polluting entities the flexibility of meeting certain performance criteria may produce better environmental results than prescribing specific technologies or approaches. A significant body of literature supports the need to develop regulatory programs that incorporate these concepts. However, there is little evidence that these concepts have been integrated into actual multimedia regulatory programs. Argonne National Laboratory and the U.S. Department of Energy are developing a prototype regulatory program for petroleum refineries that embraces these concepts. The development approach in this case study comprises several steps: (1) identifying and evaluating existing regulations governing petroleum refineries (if any); (2) characterizing expected future operating conditions of refineries; (3) setting goals for the regulatory program; (4) identifying and evaluating options for the program; (5) developing a prototype based on selected options; (6) identifying and addressing implementation issues; and (7) testing the prototype on a pilot basis. The approach being used in the U.S. effort is flexible and can be used in environmental management efforts throughout the Pacific Basin--in both developing and developed countries.

Directory of guidance documents relating to biodiversity and cultural knowledge research and prospecting

Description: Biodiversity in both developing and developed countries has been accessed for a long time by local communities as well as by outside researchers and corporate prospectors. Such activities are carried out for various purposes. Sometimes plants, animals and habitats are merely described, other times the goal is to extract for profit. These activities have helped to advance knowledge and create awareness of how precious biodiversity is. These activities have also generated many products that contribute to the health and well-being of global consumers, but may not necessarily provide benefits to their original stewards. Research has also focused attention on particular features of biodiversity. Biodiversity has been conserved, both by local community traditions, and by more formal means, with varying degree of effectiveness. One recently proposed means is the Convention on Biological Diversity. That convention has been ratified by large number of countries and has stimulated global concern over this issue. It has provided a framework for conserving biodiversity. At the same time many local communities, NGOs and people`s organizations are advancing alternative ways to conserve biodiversity and cultural diversity. In many places, the conservation of biodiversity and the protection of cultural diversity are inescapably intertwined. Despite strong links between biodiversity and the land and the water management traditions of the 6000 linguistically distinct cultures, the Convention on Biological Diversity focuses on nation-state sovereignty over biodiversity. We believe that local communities should have greater say in whether and how biodiversity is studied, extracted and commercialized. We consider prior informed consent to be a necessary requirement of such explorations, as is equitable sharing of any benefits arising from them.

Projections of motor vehicle growth, fuel consumption and CO{sub 2} emissions for the next thirty years in China.

Description: Since the early 1990s, China's motor vehicles have entered a period of fast growth resultant from the rapid economic expansion. As the largest developing country, the fast growth of China's motor vehicles will have tremendous effects on the world's automotive and fuel market and on global CO{sub 2} emissions. In this study, we projected Chinese vehicle stocks for different vehicle types on the provincial level. First, we reviewed the historical data of China's vehicle growth in the past 10 years and the correlations between vehicle growth and economic growth in China. Second, we investigated historical vehicle growth trends in selected developed countries over the past 50 or so years. Third, we established a vehicle growth scenario based on the historical trends in several developed nations. Fourth, we estimated fuel economy, annual mileage and other vehicle usage parameters for Chinese vehicles. Finally, we projected vehicle stocks and estimated motor fuel use and CO{sub 2} emissions in each Chinese province from 2000 to 2030. Our results show that China will continue the rapid vehicle growth, increase gasoline and diesel consumption and increased CO{sub 2} emissions in the next 30 years. We estimated that by year 2030, Chinese motor vehicle fuel consumption and CO{sub 2} emissions could reach the current US levels.

Establishing Junior-level Colleges in Developing Nations: a Site Selection Process Using Data From Uganda

Description: This research synthesizes data and presents it using mapping software to help to identify potential site locations for community-centered higher education alternatives and more traditional junior-level colleges in Uganda. What factors can be used to quantify one site over another for the location of such an institution and if these factors can be isolated; why should they be used by local authorities? the variables are secured from the Southern and Eastern Africa Consortium for Monitoring Educational Quality (SACMEQ), Afrobarometer, census data, as well as technology reports and surveys. These variables are reduced, grouped and mapped to help determine the best location for a junior-level college. the use of local expert opinion on geopolitical, economic, and educational situations can be interfaced with the database data to identify potential sites for junior-level colleges with the potential to reduce the failure rate of such post-secondary school ventures. These data are analyzed in the context of reported higher education policies and outcomes from the national ministries, United Nations Educational, Scientific and Cultural Organization (UNESCO), quality assurances agencies in the region, the World Bank, and national datasets. the final product is a model and tool that can be used by local experts to better select future sites to expand higher education, especially in rural areas in the least developed countries.

Application of stochastic differential geometry to the term structure of interst rates in developed markets

Description: This paper deals with further developments of the new theory that applies stochastic differential geometry (SDG) to dynamics of interest rates. We examine mathematical constraints on the evolution of interest rate volatilities that arise from stochastic differential calculus under assumptions of an arbitrage free evolution of zero coupon bonds and developed markets (i.e., none of the party/factor can drive the whole market). The resulting new theory incorporates the Heath-Jarrow-Morton (HJM) model of interest rates and provides new equations for volatilities which makes the system of equations for interest rates and volatilities complete and self consistent. It results in much smaller amount of volatility data that should be guessed for the SDG model as compared to the HJM model. Limited analysis of the market volatility data suggests that the assumption of the developed market is violated around maturity of two years. Such maturities where the assumptions of the SDG model are violated are suggested to serve as boundaries at which volatilities should be specified independently from the model. Our numerical example with two boundaries (two years and five years) qualitatively resembles the market behavior. Under some conditions solutions of the SDG model become singular that may indicate market crashes. More detail comparison with the data is needed before the theory can be established or refuted.

Gas Hydrates Research Programs: An International Review

Description: Gas hydrates sediments have the potential of providing a huge amount of natural gas for human use. Hydrate sediments have been found in many different regions where the required temperature and pressure conditions have been satisfied. Resource exploitation is related to the safe dissociation of the gas hydrate sediments. Basic depressurization techniques and thermal stimulation processes have been tried in pilot efforts to exploit the resource. There is a growing interest in gas hydrates all over the world due to the inevitable decline of oil and gas reserves. Many different countries are interested in this valuable resource. Unsurprisingly, developed countries with limited energy resources have taken the lead in worldwide gas hydrates research and exploration. The goal of this research project is to collect information in order to record and evaluate the relative strengths and goals of the different gas hydrates programs throughout the world. A thorough literature search about gas hydrates research activities has been conducted. The main participants in the research effort have been identified and summaries of their past and present activities reported. An evaluation section discussing present and future research activities has also been included.

Future prospects for networking in the United States

Description: When considering networks on the basis of geographical scope (i.e., local to wide area networks), the focus is often on the lower three layers of the International Standards Organization Open Systems Interconnection Reference Model (OSI/RM). By contrast, the upper three layers of the Model deal not so much with transport as with network services that are to a first approximation independent of geographical scope. Using this theme, the paper first discusses United States trends in local, metropolitan, and wide area networks. Following this is a description of computer services needed and advances in services offered by networks; an area of increasing emphasis in the United States. Finally, consideration is given to the impact that such trends may have on high energy physics and US HEPnet. The time horizon considered here is limited to mid-decade or a little beyond because studies of technology forecasting beyond five to six years have been shown to be inaccurate. This paper concentrates on computer networks. Through the mid-1990's there appears to be no significant technical or cost advantage for integrating voice and data. 5 refs., 7 figs.

Energy R and D in the Industrialized World: Retrenchment and Refocusing

Description: This report presents preliminary findings from an ongoing research project examining trends in energy R&D investments in selected industrialized countries (The United States, Japan, Germany, the Netherlands, and the European Union). Its underlying purpose is to assess the adequacy of current energy R&D, in terms of investment levels and programmatic scope considering the likely energy technology demands associated with international efforts to address global climate change. It finds that, while overall levels of public and private investment in all forms of R&D have risen significantly across the countries studied, investments in energy R&D have declined in real terms. Causes of the observed decline might include the ongoing deregulation of the energy industries, the absence of acute energy crises, and shifts in domestic social and policy priorities in the post-Cold War period. In addition, it finds noteworthy shifts within industrialized countries' energy R&D investment portfolios. In most countries, nuclear R&D has declined (by more than 90% in key countries such as the U.S. and Germany) while the remaining R&D resources are shifting toward shorter-term projects, most notably in the energy efficiency area. Research on carbon sequestration, hydrogen production, and fuel cells is gaining in prominence public sector energy R&D, often displacing traditional fossil energy R&D projects. Future research associated with this project will include the preparation of reports on several additional industrialized countries, including the United Kingdom, France, Italy, Canada, and Switzerland. Collectively, the small set of countries addressed in this project account for over 95% of the world's energy R&D.

Small geothermal electric systems for remote powering

Description: This report describes conditions and costs at which quite small (100 to 1,000 kilowatt) geothermal systems could be used for off-grid powering at remote locations. This is a first step in a larger process of determining locations and conditions at which markets for such systems could be developed. The results suggest that small geothermal systems offer substantial economic and environmental advantages for powering off-grid towns and villages. Geothermal power is most likely to be economic if the system size is 300 kW or greater, down to reservoir temperatures of 100{degree}C. For system sizes smaller than 300 kW, the economics can be favorable if the reservoir temperature is about 120{degree}C or above. Important markets include sites remote from grids in many developing and developed countries. Estimates of geothermal resources in many developing countries are shown.

Final Technical Report: "Representing Endogenous Technological Change in Climate Policy Models: General Equilibrium Approaches"

Description: The research supported by this award pursued three lines of inquiry: (1) The construction of dynamic general equilibrium models to simulate the accumulation and substitution of knowledge, which has resulted in the preparation and submission of several papers: (a) A submitted pedagogic paper which clarifies the structure and operation of computable general equilibrium (CGE) models (C.2), and a review article in press which develops a taxonomy for understanding the representation of technical change in economic and engineering models for climate policy analysis (B.3). (b) A paper which models knowledge directly as a homogeneous factor, and demonstrates that inter-sectoral reallocation of knowledge is the key margin of adjustment which enables induced technical change to lower the costs of climate policy (C.1). (c) An empirical paper which estimates the contribution of embodied knowledge to aggregate energy intensity in the U.S. (C.3), followed by a companion article which embeds these results within a CGE model to understand the degree to which autonomous energy efficiency improvement (AEEI) is attributable to technical change as opposed to sub-sectoral shifts in industrial composition (C.4) (d) Finally, ongoing theoretical work to characterize the precursors and implications of the response of innovation to emission limits (E.2). (2) Data development and simulation modeling to understand how the characteristics of discrete energy supply technologies determine their succession in response to emission limits when they are embedded within a general equilibrium framework. This work has produced two peer-reviewed articles which are currently in press (B.1 and B.2). (3) Empirical investigation of trade as an avenue for the transmission of technological change to developing countries, and its implications for leakage, which has resulted in an econometric study which is being revised for submission to a journal (E.1). As work commenced on this topic, the U.S. withdrawal from Kyoto and the administration's announcement of ...

Improving energy efficiency: Strategies for supporting sustained market evolution in developing and transitioning countries

Description: This report presents a framework for considering market-oriented strategies for improving energy efficiency that recognize the conditions of developing and transitioning countries, and the need to strengthen the effectiveness of market forces in delivering greater energy efficiency. It discusses policies that build markets in general, such as economic and energy pricing reforms that encourage competition and increase incentives for market actors to improve the efficiency of their energy use, and measures that reduce the barriers to energy efficiency in specific markets such that improvement evolves in a dynamic, lasting manner. The report emphasizes how different policies and measures support one another and can create a synergy in which the whole is greater than the sum of the parts. In addressing this topic, it draws on the experience with market transformation energy efficiency programs in the US and other industrialized countries.

AIJ in the Non-Energy Sector in India: Opportunities and Concerns

Description: Although the U.N. Framework Convention on Climate Change (FCCC) has been signed and ratified by 168 countries, global greenhouse gas (GHG) emissions have increased substantially since the 1992 Rio Summit. In both developing countries (DCs) and industrialized countries (ICs), there has been a need to find mechanisms to facilitate environmentally sound mitigation strategies. This need led to the formation of Activities Implemented Jointly (AIJ) at the first Conference-of the Parties (COP) in 1995. In Article 4A, para 2D, the COP established an AIJ pilot phase in which Annex I (IC) countries would enter into agreements to implement activities jointly with non-Annex I parties. DCs would engage in AIJ on a purely voluntary basis and all AIJ projects should be compatible with and supportive of national environment and development goals. AIJ does not imply GHG reduction commitments by DCs. Neither do all projects undertaken during the pilot phase qualify as a fulfillment of current commitment s of Annex I parties under the COP. The current pilot phase for AIJ ends in the year 2000, a date which may be extended. Current AIJ activities are largely focused on the energy sector. The Nordic countries, for example, feel that the most important potential areas for cooperation in AIJ are fuel conversion, more effective energy production, increased energy efficiency, and reforms in energy-intensive industry (Nordic Council of Ministers, 1995). Denmark does not want to include non-energy sector projects such as carbon sink enhancement projects in the pilot phase (Nordic Council of Ministers, 1995). However, other countries, including the US, have already funded a number of forestry sector projects (Development Alternatives, 1997). Moreover, energy-sector projects involving high technology or capital-intensive technology are often a source of controversy between DCs and ICs regarding the kind of technology transferred and sharing of costs and benefits. Further, the ...

Barriers and opportunities: A review of selected successful energy-efficiency programs

Description: In industry, barriers may exist at various points in the decision making process, and in the implementation and management of measures to improve energy efficiency. Barriers may take many forms, and are determined by the business environment and include decision-making processes, energy prices, lack of information, a lack of confidence in the information, or high transaction costs for obtaining reliable information, as well as limited capital availability. Other barriers are the ''invisibility'' of energy efficiency measures and the difficulty of quantifying the impacts, and slow diffusion of innovative technology into markets while firms typically under-invest in R and D, despite the high pay-backs. Various programs try to reduce the barriers to improve the uptake of innovative technologies. A wide array of policies has been used and tested in the industrial sector in industrialized countries, with varying success rates. We review some new approaches to industrial energy efficiency improvement in industrialized countries, focusing on voluntary agreements.

Concerns About Climate Change Mitigation Projects: Summary of Findings from Case Studies in Brazil, India, Mexico, and South Africa

Description: The concept of joint implementation as a way to implement climate change mitigation projects in another country has been controversial ever since its inception. Developing countries have raised numerous issues at the project-specific technical level, and broader concerns having to do with equity and burden sharing. This paper summarizes the findings of studies for Brazil, India, Mexico and South Africa, four countries that have large greenhouse gas emissions and are heavily engaged in the debate on climate change projects under the Kyoto Protocol. The studies examine potential or current projects/programs to determine whether eight technical concerns about joint implementation can be adequately addressed. They conclude that about half the concerns were minor or well managed by project developers, but concerns about additionality of funds, host country institutions and guarantees of performance (including the issues of baselines and possible leakage) need much more effort to be adequately addressed. All the papers agree on the need to develop institutional arrangements for approving and monitoring such projects in each of the countries represented. The case studies illustrate that these projects have the potential to bring new technology, investment, employment and ancillary socioeconomic and environmental benefits to developing countries. These benefits are consistent with the goal of sustainable development in the four study countries. At a policy level, the studies' authors note that in their view, the Annex I countries should consider limits on the use of jointly implemented projects as a way to get credits against their own emissions at home, and stress the importance of industrialized countries developing new technologies that will benefit all countries. The authors also observe that if all countries accepted caps on their emissions (with a longer time period allowed for developing countries to do so) project-based GHG mitigation would be significantly facilitated by the improved private investment ...

Energy efficiency programs and policies in the industrial sector in industrialized countries

Description: About 37% of the primary energy consumed both in the U.S. and globally is used by the industrial sector. A variety of energy efficiency policies and programs have been implemented throughout the world in an effort to improve the energy efficiency of this sector. This report provides an overview of these policies and programs in twelve industrialized nations and the European Union (EU). We focus on energy efficiency products and services that are available to industrial consumers, such as reports, guidebooks, case studies, fact sheets, profiles, tools, demonstrations, roadmaps and benchmarking. We also focus on the mechanisms to communicate the availability and features of these products and services and to disseminate them to the industrial consumers who can use them. Communication channels include customer information centers and websites, conferences and trade shows, workshops and other training mechanisms, financial assistance programs, negotiated agreements, newsletters, publicity, assessments, tax and subsidy schemes and working groups. In total, over 30 types of industrial sector energy efficiency products, services and delivery channels have been identified in the countries studied. Overall, we found that the United States has a large variety of programs and offers industry a number of supporting programs for improving industrial energy efficiency. However, there are some products and services found in other industrialized countries that are not currently used in the U.S., including benchmarking programs, demonstration of commercialized technologies and provision of energy awareness promotion materials to companies. Delivery mechanisms found in other industrialized countries that are not employed in the U.S. include negotiated agreements, public disclosure and national-level tax abatement for energy-efficient technologies.

Shape of the microgrid

Description: Restrictions on expansion of traditional centralized generating and delivery systems may be becoming so tight in the industrialized countries that they cannot reasonably be expected meet future electricity demand growth at acceptable cost. Meanwhile, technological advances, notably improved power electronics that permit grid interconnection of asynchronous generation sources, is tilting the economics of power generation back towards smaller scales, thereby reversing a century long trend towards the central control paradigm. Special power quality requirements or opportunities for combined heat and power applications make on-site generation an even more attractive option for customers. The existence of a significant amount of electricity sources dispersed throughout the low voltage distribution system could create a power system quite different to the one we are familiar with and creating it offers significant research and engineering challenges. Moreover, the electrical and economic relationships between customers and the distribution utility and among customers may take forms quite distinct from those we know today. For example, rather than devices being individually interconnected in parallel with the grid, they may be grouped with loads in a semi-autonomous neighborhood that could be termed a microgrid. A microgrid is a cluster of small (by the standards of current power systems, e.g. < 500 kW) sources, storage systems, and loads which presents itself to the grid as a legitimate single entity. The heart of the microgrid concept is the notion of a flexible, yet controllable electronic interface between the microgrid and the familiar wider power system, or macrogrid. This interface essentially isolates the two sides electrically; and yet connects them economically by allowing delivery and receipt of electrical energy and ancillary services (EE&AS) at the interface. From the customer side of the interface, the microgrid should appear as an autonomous power system meeting the power quality and reliability requirements of the customer. ...

Organic Geochemical and tectonic evolution of the Midcontinent Rift system

Description: The older assemblages stand in contrast with the ca. 1000 Ma old Hunting Formation, Arctic Canada, which contains what may be the oldest evidence for modem algae - red algal fossils that compare closely with members of the extant family Bangiophyceae (Butterfield et al., 1990). Taken together the Nonesuch, Shaler, Hunting and other assemblages support the hypothesis of a major episode of eukaryotic diversification ca. 1000 Ma ago. Prior to this time, eukaryotic primary producers must have been physiologically primitive (and now extinct) algae whose abundance in ecosystems is poorly constrained by analogies with the present oceans. Cyanobacteria were major primary producers in a wide range of marine environments. After 1000 Ma, diversifying red green and chromophyte algae contributed significantly to primary production in all save microbial mat communities in restricted environments. It bears mention that such mat communities remained significant potential sources of buried organic matter until the end of the Proterozoic, necessitating exploration strategies that differ from those commonly employed for younger rocks (Knoll, in press). As in Phanerozoic basins, petroleum exploration in Proterozoic rocks requires tools for stratigraphic correlation. In Neoproterozoic (<1000 Ma) rocks, biostratigraphy is possible, and it is aided significantly by C and Sr isotopic chemostratigraphy. New data from the Shaler Group contribute to the construction of C and Sr isotopic curves for Neoproterozoic time, making possible much improved chronostratigraphy for this time interval.

Structure and Emplacement of the Magmatic Intrusions Beneath the Valley of Ten Thousand Smokes

Description: The goal of this project was to provide constraints on the subsurface geometry of the vent, feeder conduit(s), and possible intrusive bodies in the Novarupta Basin, Valley of Ten Thousand Smokes (VTTS), Katmai National Park, Alaska. This research was designed to support the Katmai Drilling Project, a consortium involving the DOE, NSF, other government agencies, and several universities. Our work aimed at providing information to help guide site selection and identify targets for the drilling program. However, our research also has contributed to the understanding of silicic volcanic systems in general. Understanding the subsurface geometry of the vent is essential for accurately modeling the present thermal regime in the vent region and the eruption dynamics. Determining the origin of surficial fractures indicated the effect of compaction and consolidation of tephra and orientation of the depositional surface on fracture formation. Our research plan included (1) completion of a detailed topographic-structural map of surface fractures including spatial distribution and relative displacements; (2) numerical modeling studies that related surface fractures to major subsurface structures; and (3) interpretation of the origin of surface fractures in light of these model studies.

Military Spending, External Dependence, and Economic Growth in Seven Asian Nations: a Cross-National Time-Series Analysis

Description: The theme of this study is that seven major East Asian less developed countries (LDCs) have experienced "dependent development," and that some internal and external intervening factors mattered in that process. Utilizing a framework of "dependent development," the data analysis deals with the political economy of development in these countries. This analysis supports the fundamental arguments of the dependent development perspective, which emphasize positive effects of foreign capital dependence in domestic capital formation and industrialization in East Asian LDCs. This perspective assumes the active role of the state, and it is found here to be crucial in capital accumulation and in economic growth. This cross-national time-series analysis also shows that the effects of external dependence and military spending on capital accumulation and economic growth can be considered as a regional phenomenon. The dependent development perspective offers a useful way to understand economic dynamism of East Asian LDCs for the past two decades.
