To Light Or Not To Light? -- That Is The Energy Question, J. Byron Nelson, Burns E. Hegler

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

The controversy over lighting levels has existed for some time. Interest in methods of lighting has been heightened by the energy crisis. It has been estimated that lighting consumes approximately five percent of the nation's energy, therefore lighting is a relatively small energy user when compared to transportation and industrial processes which consume the bulk of the nation's energy. However, any saving that will make a contribution to the energy crisis should be considered. Consequently, this paper shows how energy for lighting may be reduced without sacrificing the present quality of lighting and in some cases, actually improve the lighting …

Consumers’ Attitude Toward Energy Conservation In A Middle-Size City, Mangi Agarwal, Dan Johnson

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

This study explores the attitude of household consumers toward conservation in their electrical usage. It examines whether a time-of-day pricing structure will influence their response to shifting their electrical usage from peak to non-peak hours. It also attempts to measure their perceived elasticity of electricity consumption.

Heat Pumps Without Supplemental Heat, Carl W. Glaser

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

Through the past few years, fuel used to generate electricity has climbed steadily in cost resulting in a new and much higher level of acceptance for the air to air heat pump system. Manufacturers have improved the product tremendously and have established a level of reliability approaching that of the conventional air conditioner. The fact that heat pumps reduce the cost of heating by 30% to 50% over conventional electric resistance heating and that natural gas is not available in many parts of the country has resulted in more and more heat pumps being installed in homes. While the benefits …

Development Of Industrial Owned, Small Hydroelectric Facilities, John S. Krikorian Jr.

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

A methodology is discussed for determining the economic feasibility of reclaiming industrial owned, small hydroelectric facilities. A cash flow computer model provides the means for coping with many of the diverse inputs that occur at different sites. A detailed case study is presented. Some institutional factors that aid or hinder development are discussed.

Attainability And Nonattainability Under Anti-Pollution Laws, J. David Reed, John H. Hoag

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

The central issue with which this paper deals is the effectiveness of alternative air pollution control standards presently in use in the United States. More specifically, an analysis and comparison of effluent air standards versus ambient air standards will be performed. The question of effectiveness will be in the context of how well the alternative pollution control measures achieve society's expectations as goals when the standards are imposed. Society's views are assumed to be reflected through a regional (state) planner. The analysis is performed through the use of optimal control techniques. Initially the effluent air standards model will be examined. …

The Energy Needs Of The Developing Countries, Vaman Rao

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

The energy needs of the developing countries are enormous. They will grow with the passage of time as the pace of economic development accelerates and those countries enter the industrial epoch. The sheer physical non-availability of coal and petroleum to most of them makes it obligatory to choose an unconventional resource as an energy-base. The nuclear fission is the only option now available which is feasible, less-expensive and plentiful. Solar and fusion may be the ultimate sources in the steady state, when appropriate technologies are developed.

Solar Heated Animal Shelters, Joan M. Wood

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

Modern day agricultural methods have made todays farmers dependent upon fossil fuels to maintain their productivity. This paper addresses one aspect of the problem -- the heating of animal shelters. In particular, the solar heating of a broiler grow-out house, where temperatures of up to 95°F must be maintained, is discussed.

A detailed analysis of a solar heated broiler grow-out house that has been operating for over a year will be presented. The solar system provided 47% of the heat required to grow 22,000 chickens. The system utilizes a 3,200 ft.2 integrated rock absorption and storage collector. An economic analysis …

Improving Energy Efficiency By Federal Regulation, Barry Hyman, Burns E. Hegler

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

This paper examines the scope and nature of federal activities devoted to improving the efficiency of energy utilization in buildings, consumer products, motor vehicles, and industrial processes and equipment. Several forms of regulation are identified and their characteristics are explored. It is postulated that consistency of an overall policy of energy efficiency regulation can be ascertained from the examination of a regulatory policy matrix.

Heat Recovery Devices For Building Hvac Systems, Ronald H. Howell, Harry J. Sauer Jr.

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

The opportunities and advantages of air-to-air heat recovery are described. The five basic types (rotary regenerative, coil loop run around, open run-around, heat pipe, and plate type) are described and their typical performance is presented. The potential savings in operating costs as well as initial equipment costs for common applications are presented.

Agricultural Crop Drying And Space Heating Using A Solar Energy Intensifier, M. A. Hellickson, W. H. Peterson, S. E. Saienga, J. L. Julson

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

A solar energy-intensifier-thermal energy storage system was developed and tested under actual climatic conditions in South Dakota. Performance characteristics of the system are presented for its use in drying shelled corn and for agricultural space heating. Comparisons between solar and conventional drying between solar supplemented and conventional heating are reported.
