Solar Assisted Power Systems, A. G. Potter

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

Except for hydroelectric power, solar electric generation has not been widely used in the past to assist power system generation because of its relatively high cost. This situation has now started to change with the advent of the energy crisis as exemplified by decreasing natural gas supplies and increasing fossil fuel prices. One possible response to this situation which appears to have a relatively good chance for economic success is the utilization of wind and solar thermal energy for space and water heating loads served by natural gas or electric power. Unfortunately, a large portion of the energy collected in …

Wind Energy Concentrators, John L. Loth

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

This paper presents two alternatives to the shrouded propeller wind energy concentrator. Their operation is based on generating a low pressure area, with high local wind velocity, around the windmill rotor.

The two types of wind energy concentrators considered are: (1) the "obstruction type" concentrator where a vertical cylinder or vertical flat surface is used to produce high local velocities around two counter-rotating vertical axis rotors, and (2) the "vortex type" concentrator where a horizontal vortex is generated by a vertical high lift wing of finite span. The high local wind kinetic energy inside the vortex is harnessed by a …

Energy From Agriculture, E. C. Clausen, D. L. Million, Efton Park, J. L. Gaddy

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

During the past few years, the demand for energy and petrochemicals has grown at a pace so rapid that our reserves of fossil fuels, once considered inexhaustible, are now being quickly depleted. To help lessen this impending problem, alternative sources of energy must be rapidly developed.

Of the many new sources of energy being studied, solar energy, undisputedly, is the most inexhaustible. Energy from the sun, incident upon the earth's surface, exceeds by nearly three orders of magnitude the total energy consumption today. Furthermore, it is not subject to nationalistic boundaries and its use would be compatible with our environmental …

Energy Management In The Food Store, Paul Adams

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

Food store refrigeration is vital to the food distribution system and consumes much of the energy used in a supermarket. The manufacturers of food store display equipment have worked long and hard to develop new ideas in supermarket energy conservation. 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 …

Planned Reduction In Electrical Energy Use In Nashville - Davidson County, Tennessee: A Preliminary Assessment, Barry D. Lichter, William F. Flanagan, Robert S. Goodrich, James K. Sebenius, C. Paul Beach

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

An assessment was carried out of the impacts of the various alternative strategies designed to reduce the rate of electrical energy use in the Nashville-Davidson County area, in the light of a potential crisis in supply. Seven strategies were identified among the major categories of voluntary reduction, price regulation, and mandatory reduction. Thirty-three sub-sectors were identified among residential, commercial and industrial users, and the consequences of imposing the strategies were assessed using a cross-impact matrix. The value of the methodology as an aid to public policy formulation lies in its possible extension to allow direct participation of various affected publics.

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 …

Natural Resource Pricing And Economic Development, Vaman Rao

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

In a competitive equilibrium the price of a natural resource will be increasing at a rate equal to the social time preference rate, but in a monopoly market, the price will be increasing at less than social time preference rate. If the producer countries utilise their monopoly of production and sale of a natural resource for the purpose of developing their economies, the price of the natural resource will be growing at the rate at which the producer countries' economies are growing, whether or not the sales proceeds are used to finance their investment programmes, fully or partly.
