The contribution of households to CO 2 production is still increasing. To alter patterns of energy consumption for example with respect to commuter traffic, using the freezer, and warming the house, changing life styles related to domestic energy consumption is considered. In our study, we have operationalized life style as means-end chains, that link perceived benefits of a particular behavior to basic values that people pursue. In this paper, preliminary results are presented of the study that is aimed at empirically establishing the feasibility of the concept of life style in relation to domestic energy consumption.
During the past three years, working with more than 150 organizations representing public and private stakeholders, EPRI has developed the Electricity Technology Roadmap. The Roadmap identifies several major strategic challenges that must be successfully addressed to ensure a sustainable future in which electricity continues to play an important role in economic growth. Articulation of these anticipated trends and challenges requires a detailed understanding of the role and importance of reliable electricity in different sectors of the economy. This report is intended to contribute to that understanding by analyzing key aspects of trends in the economic value of electricity reliability in the U.S. economy. We first...
Coalbed methane is one of the most important and valuable natural resources in the Western United States. The natural gas that results from CBM development is the cleanest burning fossil fuel, and the extensive domestic supply makes it a central element of the national goal of a secure supply of energy. Demand for natural gas will continue to grow and CBM will play an increasingly larger role in meeting that demand. CBM production has expanded tremendously over the past decade, and the rapidity with which development has expanded has resulted in stresses and tension in affected communities. Development of this important energy resource must be balanced with a number of other important goals of protecting water,...
This article underlines the main implications of the interrelations between the energy problem and that of environmental pollution, using the most widely used macroeconomic indicators in the field of policy analysis. In fact, carbon dioxide (CO2) emission intensity and energy intensity trends may be used to highlight the most important features of economic development over a given time scale in a variety of different countries. The empirical analysis proposed here—covering a time-span of some 40 years in a number of the most highly industrialised nations—seems to be useful if we are to understand the main similarities and differences in the interaction between the energy choices made by different countries and their...
Policymakers and managers in the U.S. energy sector will face complex multidimensional challenges as they confront potential supply shortfalls, infrastructure constraints, and environmental limitations in the years ahead. Using a technique known as scenario analysis, this paper investigates key energy issues and decisions that could improve or reduce the ability of the United States to deal with the uncertainties that may challenge the U.S. economy during the next fifty years. Four scenarios have been developed representing a diverse range of future worlds to explore the driving forces and critical uncertainties that may shape U.S. energy markets and the economy for the next fifty years. Each scenario has been quantified...

By replacing fossil fuels bioenergy has the potential to reduce greenhouse gas (GHG) emissions, but indirect effects might partly or even completely eliminate this benefit. Production of bio-energy products, such as biofuels for transport, causes several indirect effects through their interactions with the global economic and physical systems. Indirect land-use change leads to GHG emissions – in some cases in the same order of magnitude as the fossil emissions – and loss of nature, but there are other relevant indirect effects as well. Intensification of agricultural production is another indirect effect and could be stimulated more to minimise the undesirable land conversion. However, intensification through increased...
This is the final report of a two-year, Laboratory-Directed Research and Development (LDRD) project at the Los Alamos National Laboratory (LANL). Initially, the project focused on creating an ocean oil spill model and working with the major oil companies to compare their data with the Los Alamos global ocean model. As a result of this initial effort, Los Alamos worked closely with the Eddy Joint Industry Project (EJIP), a consortium oil and gas producing companies in the United States. The central theme of our project was to use output produced from LANL's global ocean model to look in detail at ocean currents in selected geographic areas of the world of interest to consortium members. Once ocean currents are well...

In order to promote the production and use of electricity generated from renewable energy sources, support schemes such as the Renewables Portfolio Standard and various green power programs have been implemented. When evaluating the costs and benefits associated with those schemes, people need accurate information about the characteristics of renewable generation. The objective of the present paper is to identify the kind of information to be provided to lay people in Japan in order to enhance their understanding of biomass generation. We used the two-stage "mental model" method to conduct open-ended interviews and a questionnaire survey to reveal people's beliefs about biomass generation. From the survey results,...
Wind power is a fast-growing energy source for electricity production, and some environmental impacts (e.g. noise and bird collision) are pointed out. Despite extensive land use (2600-6000 m(2)/MW), it is said that most of these impacts have been resolved by technological development and proper site selection. The results in this paper suggest that: (i) wind farms kill millions of birds yearly around the world, and the high mortality of rare raptors is of particular concern; (ii) wind farms on migration routes are particularly dangerous, and it is difficult to find a wind power site away from migration routes because there is no guarantee that migration routes will not vary; (iii) according to the presented model...

To investigate the potential response of soils to climatic change, measurements of soil physical and chemical properties were carried out during a year in a mountain zone in Alicante (Spain), along an altitudinal and climatological gradient. Hydrological properties (infiltration runoff and sediment concentration) were measured under winter and summer conditions. Chemical and physical soil properties were analyzed for reference soil profiles along the transect. The erosional response of the soils as well as soil properties like organic matter and CEC are found to be under the direct influence of the climate, and as a result they have to be considered as important factors in the desertification processes.

Natural gas plays a key role in our nation’s clean energy future. Recent advances in drilling technologies—including horizontal drilling and hydraulic fracturing—have made vast reserves of natural gas economically recoverable in the US. Responsible development of America’s oil and gas resources offers important economic, energy security, and environmental benefits. Hydraulic fracturing is a well stimulation technique used to maximize production of oil and natural gas in unconventional reservoirs, such as shale, coalbeds, and tight sands. During hydraulic fracturing, specially engineered fluids containing chemical additives and proppant are pumped under high pressure into the well to create and hold open fractures...
Sequestration of carbon dioxide (CO2) in depleted oil reservoirs is one of the viable options for carbon management. This paper describes the preliminary modeling and flow simulation part of a DOE sponsored CO2 sequestration project. The main objective of the project is to understand the feasibility of long term sequestration of CO2 in a depleted oil reservoir through a field demonstration experiment. Before the actual CO2 injection begins, it was necessary to determine feasibility of injection. Advanced geologic modeling and flow simulation techniques were used to develop a model for the proposed target interval. A geologic model was developed using data available from well logs and cores. Subsequently, porous...

A visual impact evaluation method specifically designed to assess landscape alteration as a result of surface mining and quarrying would represent a fundamental aid for both those involved in the early stages of mine planning and design (mining companies) and those in charge of controlling and verifying environmental impacts (government authorities). This research is based on implementation of the visual impact indicator Lvi, which takes into account two parameters among those physically measurable: the extent of visible alteration in the landscape and the chromatic contrast between bare rock and the surrounding environment. Both parameters can be quantified by processing one or more digital images taken from the...

To meet the India’s projected power demand over the next 25 years, over 300,000 MW of new e generating capacity will need to be installed. Cogeneration, the combined generation of steam and electricity, is an efficient and cost-effective means to save energy and reduce pollution. Many studies around the world have identified sugar mill cogeneration as an attractive low-cost option to place additional generating capacity on the grid. Most studies estimate the cogeneration potential of India’s sugar industry at around 3500 MW . e The United States Agency for International Development (USAID) has implemented a Greenhouse Gas Pollution Prevention (GEP) Project to assist in the direction and pace of India’s power sector...
