Comparative Residential Energy Consumption And Fuel Costs With Various Types Of Systems: Oil-, Gas-, Electric-Furnaces And Heat Pumps, Ronald Hunter Howell, Harry J. Sauer Jr.

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

The electric air-to-air heat pump for residential heating offers an economic alternative to systems traditionally used extensively for home heating, such as, oil or gas fired furnaces and electric resistance heat. This simulation analysis showed that using 1976 mid- Missouri fuel costs, an oil fired furnace was the least expensive to operate of the three traditional type residential heating units. LP gas heating was 19% higher than oil heat while electric resistance heating was 26% higher in cost than oil. The typical air-to- air heat pumps showed a 29% reduction in the heating bill when compared to an oil furnace.

This paper discusses various approaches to reactor design. A process to produce 50 M5CFD of methane is described, and the design and economics are …


The Forgotten Fundamentals Of The Energy Crisis, Albert A. Bartlett Oct 1976

The Forgotten Fundamentals Of The Energy Crisis, Albert A. Bartlett

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

Papers at an energy conference may tend to deal with details. The details are important, but only if they relate to the national or global picture. We know that an energy crisis has motivated us to look at all manner of detail in regard to our own particular uses of energy. We hear political leaders of the United States speaking of "energy self-sufficiency" and of "Project Independence". We have the vague feeling that arctic oil from Alaska will relieve the energy crisis, and we are told that the United States is in good shape in the long run because of …


World Oil Supplies And The Next 25 Years, J. A. Eyer Oct 1976

World Oil Supplies And The Next 25 Years, J. A. Eyer

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

Petroleum must become a more efficiently used commodity while alternative energy sources are developed, but it will remain in high demand as long as the world wide availability is assured, regardless of the influence of the O.P.E.C. nations. The availability of petroleum on a country-by-country survey shows clearly that there are large known recoverable reserves as well as large potential for discovering added reserves. However, the highly industrialized nations do not have adequate petroleum supplies and this will probably not change as long as petroleum remains as the primary energy source.

The Tradeoffs Between Energy Conversion Stages, Environmental Effects, And Technical Efficiency, Angelos Pagoulatos Oct 1976

The Tradeoffs Between Energy Conversion Stages, Environmental Effects, And Technical Efficiency, Angelos Pagoulatos

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

From analyzing the physical constraints in managing exhaustible and nonrenewable energy resources it follows that decisions concerning how far to convert a given energy resource should be made within an economic framework. The tradeoffs between conversion stages, environmental effects, technical efficiency and uses satisfied by energy resources are then determined. In light of the direct and opportunity costs stemming from increased conversion stages, the intertemporal allocative decisions for exhaustible and nonrenewable energy resources are derived.

The Demand And Supply Of World Petroleum And Its Consequences For Agricultural Economic Development, Amalia Vellianitis-Fidas Oct 1976

The Demand And Supply Of World Petroleum And Its Consequences For Agricultural Economic Development, Amalia Vellianitis-Fidas

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

The concerns related to the increase cost of petroleum in 1974 and 1975 centered around the enormous transfer of funds needed to pay for petroleum imports by most countries. Although this transfer is successfully taking place in the developed countries, it is taking place with serious long run external financial consequences for the less developed countries. In addition, these countries' continued agricultural development will probably depend on finding new paths to agricultural efficiency that are not as dependent on high-priced fuels.

The analysis is concentrated on the micrometeorological effects of lakes and hills during near freezing conditions. The impetus for the study is an economic one since proper selection of a site for certain freeze susceptible crops, such as citrus, can result in huge savings of energy and resources.


The Status Of And Need For New Coal Gasification Technology, Jimmie R. Bowden Oct 1976

The Status Of And Need For New Coal Gasification Technology, Jimmie R. Bowden

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

Movement toward a domestic coal-based energy policy has been barely perceptible since the Arab oil embargo of 1973-4. Rapidly declining supplies of natural gas for small businesses and residential uses can be supplemented by coal gasification or replacement of gas by coal as a power generating fuel. At this time it probably is the better choice to use coal to generate power instead of gas. Second generation coal gasification processes under development with ERDA financial help will not change this balance in the next 10 years if at all.
