ABSTRACT: To help meet national energy demands, interest has been focused on the coal, oil shale, and uranium deposits of the Upper Colorado River Basin. Several energy output projections for the basin have been presented based upon water availability. Inherent in all these analyses are estimates as to the rate of water use in each energy development. New energy technologies are characterized by parameters extrapolated from small scale energy facilities. The data provide projected costs, conversion efficiencies, and material inputs and outputs. Alternative techniques for process cooling and solids handling provide variable rates of water use which affect other conversion parameters. Results from a mathematical model...
This paper approximates the emissions rebound effects' associated with substituting expensive and GHG emitting natural gas (LNG) power plants, with apparently cheaper and lower emitting nuclear plant. It then evaluates the effect this has on economy wide electricity use as well as net GHG emissions changes. The analysis is undertaken by combining aspects of an input-output model with an optimizing energy systems model. The scope of the case study is limited to the effects of the electricity sector (and its emissions) on the Korean economy from 2005 to 2030. Its primary basis (in terms of data and assumptions) is the recent national Basic Plan for Long-Term Electricity Supply and Demand (KPX, 2006).(2) The cases...
The article discusses a report published by the U.S. Dept. of Energy (DOE) that examined the technical feasibility of using wind energy for electricity generation. The report assessed the costs, impacts and challenges associated with the production of 20% wind energy by 2030. Results have shown that there is a need for an enhanced transmission infrastructure and an increase in turbine installations to achieve 20% wind energy.

Governmental policy options in response to increasing concern over an emerging greenhouse warming are reviewed. These will reflect differing levels of pofitical concem as understanding on the future size and impacts of the greenhouse effect evolves. High levels of concem will place emphasis on the option of limiting C02 emissions by restricting fossil fuel use. This option requires emphasis on energy efficiency and changes in energy supply, with increased use of natural gas, nuclear power or renewable energy sources. The progressive industrialization of the LDCs with the consequent growth in energy demand, may put additional pressure on developed countries to take action on this policy option.
