Hussmann's studies have uncovered a number of facts invaluable to anyone concerned with energy conservation in the supermarket.

The first fact is to realize that supermarkets are different from any other retail stores. They consume more energy each year per sq. ft. of store - or per customer - or per dollar sales than other retail stores and most commercial …

Osmo - Power. Osmotic Work; Energy Production From Osmosis Of Fresh Water/Sea-Water Systems, H. H. G. Jellinek

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

It is imperative that new and ecologically acceptable energy sources are made available. Solar energy is a source which seems to be inexhaustible and free of pollution hazards. One vast source, which can be considered to be a solar energy source consists of the system fresh water/sea water. Fresh water is continually removed by the hydrological cycle where water evaporates from the ocean due to solar radiation and is eventually precipitated again in the form of fresh water feeding various rivers. Fresh water and ocean (salt) water mix when rivers flow into the oceans. The different chemical potentials are equalized …

Alternative Approaches To Energy Modeling, Alan S. Cohen, Kenneth W. Costello

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

The effects of government and private sector energy policies are varied and interrelated. Before implementing research and development programs, new technologies, environmental and price regulations, import quotas, and other energy-related policies, the consequences of these programs must be identified and quantified on a regional basis. To evaluate the regional impacts of energy policies, we need to consider production costs, transportation costs, and the location of reserves, as well as the demands for energy and nonenergy goods. Developing techniques for analyzing these factors was the objective of many previous research efforts. The strengths and weaknesses of the resulting models are discussed …

Ways To Reduce Peak Electrical Demand In South Louisiana, S. J. Gold, M. D. Bakewell, G. E. Guidry, E. F. Lewis, L. J. Naquin, B. P. Whitney

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

This study analyses alternatives for coping with the peak electrical demand of hot summer afternoons. Economic and Political aspects, as well as technical feasibility, are included. It is concluded that South Louisiana may indeed be able to trim peak demand to 5% below what is anticipated by 1980 , thus making one of the coal fired stations scheduled then unnecessary. However, the contingencies (Natural Gas Shortage, Another Oil Embargo) would make a coal-fired station very desirable.

The Impact Of Direct Coupling Of Solar Cell Arrays To Electric Power Networks, Adel H. Eltimsahy, Fernando L. Alvarado, Thomas W. Boyd

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

This paper has to do with a preliminary investigation of the economic impact of solar cells when directly coupled to a conventional three-phase power network in the Toledo area.

A correlation is established between power system demand curves and solar insolation data in the Toledo area using computer simulation. The correlation studies determine how successfully solar cell/inverter systems can alleviate the power system demand during peak hours. They also show how much solar cell area will be needed to cause a significant impact on the power generating system.

Using computer simulation the initial cost of the solar cell/inverter is compared …

Choosing Alternative Energy Systems Under Conditions Of Uncertainty, Dennis Costello

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

A methodology for simulating the decision process of an investor deciding between alternative energy systems is presented. The approach assumes the investor bases his decision on cost (or rate of return) and risk. Risk is treated directly in the model and not reduced to a certainty equivalent. The rate of return-risk characteristics of many system combinations allows them to be eliminated as viable choices to the investor without reference to his personal attitude toward risk.

Oil Shale R & D -- A Bureau Of Mines Program, Steve Utter

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

Energy is one of our basic natural resources. Oil constitutes an important part of this resource but domestic production is dropping while imports are rising. Today, oil represents about one-half of the total energy consumed in this country, and demand is expected to grow at the rate of about 2 percent per year during the next 10 years. Increased reliance on imports can be reduced by synthetic fuels produced from the oil shale deposits of the Green River Formation in Colorado, Utah, and Wyoming. These deposits are so enormous (600 billion barrels in high- grade shale alone), that any limitations …
