The total energy requirements of household consumption of all goods and services have been calculated. Source for consumption data is the 1972–1973 Bureau of Labor Statistics (BLS) Consumer Survey. These are converted to energy terms using input-output energy intensities. The dependence of...

This contains my goals for, and reactions to, the Panel on ‘Strategies’ at the Workshop, ‘Advances in Energy Studies: Exploring Supplies, Constraints, and Strategies’, 23–27 May 2000, Porto Venere, Italy. The very ambitious goals for the four speakers were not fully realized; hence my...

We have applied standard energy analysis to 4 types of geothermal-electric technologies: liquid dominated, hot dry rock, geopressure, and vapor dominated. We find that all are net energy producers, i.e. they have an energy ratio exceeding unity, where energy ratio = net electric energy produced...

Combined generation of process steam and electric power in coal-fired industrial power plants is examined, and a rate of return on various investments of this type is estimated. The effect on these rates of return of a 20% investment tax credit is calculated, which appears to be slight. We note...

When we use the Cobb-Douglas equation to investigate economic growth, we require data on the levels of the capital and labor inputs, and corresponding data on the level of output, at different points in time. We conclude that the inclusion of energy in the standard Cobb Douglas production...

Methanol (MeOH) and ethanol (EtOH) are industrial alcohols that can be used as liquid fuels. They may be obtained from renewable or non-renewable feedstocks. The production processes and end uses are analyzed in order to assess the potential energy savings introduced by alcohol production from...

Most prior net-energy studies of nuclear-power systems accounted only for the direct consumption of fuels and the indirect consumption of energy embodied in physical materials when making such estimates. Most ignored the energy embodied in labor, government, and financial services. In this...

Geopressured gas is a vast but diffuse fuel resource in the U.S. Gulf Coast Region. The U.S. Department of Energy sponsored a test drilling program to evaluate the physical parameters of the resource base. Data from this evaluation program and other studies were incorporated into a model that...
