Economics And Net Energy Analysis: Is A New Analytical Technique Needed For Energy Decision Making?, William J. Kruvant Oct 1977

Economics And Net Energy Analysis: Is A New Analytical Technique Needed For Energy Decision Making?, William J. Kruvant

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

The paper attempts to evaluate the claims of Net Energy Analysis (NEA) against those of economics in a reasonably comprehensive way. The principal problems of NEA concern system boundaries, aggregation across fuels, valuing external effects, valuing human labor and valuing time. These problems seriously limit the contribution Net Energy Analysis can make to allocation decisions, and allocation Is the central problem of energy policy.


Volunteers In Energy Conservation -- Potential And Problems, Clayton L. Smith Oct 1977

Volunteers In Energy Conservation -- Potential And Problems, Clayton L. Smith

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

The social and political implications of the energy crisis, while complex in nature and understanding, seem to urgently proclaim that the time for action is now. This paper is based on the premise that individual responsibility is essential. The people must act. Political decisions must be made. The people must debate what social climates are to be promoted and by what new energy systems. The key to solving the energy crisis is America's people, and particularly with its youth. With people come the potential and of course, the problems. The approach of this paper will be threefold.


An Overview Of Potential Impacts Of Changing Petroleum Energy Prices On Grain Farms, Jean-Paul Chavas, James B. Kliebenstein Oct 1977

An Overview Of Potential Impacts Of Changing Petroleum Energy Prices On Grain Farms, Jean-Paul Chavas, James B. Kliebenstein

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

Since the early 1970s world fossil fuel energy prices have risen dramatically. Assuming there is no significant breakthrough in en- ergy technology, the world will see further increases in energy prices. These changes will likely lead to economic adjustments in U. S. agriculture. A firm level linear programming model is used to evaluate what some of these adjustments could be on a Missouri grain farm. To obtain expected energy price affects on production mixes, energy prices are changed parametrically. Potential crop adjustments are from corn to single-crop soybeans to wheat as energy prices increase. Fertilization adjustments are from chemical to …


The Impact Of Changing Net Returns On Minimum Energy Requirements For Grain Farms, James B. Kliebenstein, Robert M. Finley, Douglas C. Farthing Oct 1977

The Impact Of Changing Net Returns On Minimum Energy Requirements For Grain Farms, James B. Kliebenstein, Robert M. Finley, Douglas C. Farthing

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

With sources of energy more restricted and higher priced, optimal combinations of enterprises must logically be considered on the basis of energy efficiency. One method of ascertaining this efficiency is to optimize solutions for given levels of income on the basis of energy used (e.g., the objective function was in terms of energy kilocalories). In general, soybeans were most feasible at lower levels of income regardless of farm size and labor circumstance. As income levels increased, double-cropping (wheat soybeans) was first substituted and finally corn at highest income levels.


Low Head Power Generation With Bulb Turbines, J. L. Carson, R. S. Samuelson Oct 1977

Low Head Power Generation With Bulb Turbines, J. L. Carson, R. S. Samuelson

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

Because of uncertainties, delays, and high costs associated with alternative electric energy sources, many agencies responsible for generation of electrical power are investigating means of replacing or supplementing their existing hydroelectric facilities. In the head range between 10 and 60 feet, the bulb-type generating unit, in which the generator is enclosed in a metal capsule within the water passage, has many advantages, including higher efficiency and lower cost, over other types of turbines. Two of the municipalities in the United States which have recently conducted feasibility studies for installing bulb turbines in their systems are the City of Idaho Falls, …


Improving Energy Efficiency By Federal Regulation, Barry Hyman, Burns E. Hegler Oct 1977

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. Oct 1977

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.


A Systems Study Of Our Energy Problems, S. C. Lee Oct 1977

A Systems Study Of Our Energy Problems, S. C. Lee

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

The diminishing supply of petroleum and natural gas has induced many concerned citizens as well as many interest groups to study energy problems. Based on different sources of information and various degrees of economical consideration, conflicting conclusions have been reached. To help resolve this situation, a systems study was conducted. The available statistics on the supply and demand of energy were examined. The resources of nuclear energy, fossil fuel, and renewable energy sources were analyzed. Considerations were weighted equally on energy content, resource availability, existing technology, and consumer economics as well as on the impact of ecology and sociology. The …


The Impact Of Regulation Upon The Oil And Gas Industries, Lee Carter Jan 1977

The Impact Of Regulation Upon The Oil And Gas Industries, Lee Carter

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

It is paradoxical that the oil and gas industries both ask for and resist the idea of regulation. Historic examples are given of how and why this is so. Since the Arab oil crisis of 1973, new and onerous rules for domestic producers have been introduced, first by improvization and more recently by a national energy plan. Both the good and bad features of the 1977 national energy plan are reviewed to generate words of commendation and words of warning about its effect on the oil and gas industries.


Agricultural Crop Drying And Space Heating Using A Solar Energy Intensifier, M. A. Hellickson, W. H. Peterson, S. E. Saienga, J. L. Julson Jan 1977

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.
