Evaluating The Total Cost Of An On-Site Solar Energy System, Dennis Costello, Jerry Bradley
Evaluating The Total Cost Of An On-Site Solar Energy System, Dennis Costello, Jerry Bradley
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
A methodology for evaluating the total or life-cycle cost of an on-site solar energy system is presented. The costs represent after-tax or effective costs realized by the owner of the energy system. The methodology addresses: (1) capital costs; (2) fuel costs; (3) maintenance and operating costs; (4) property taxes; (5) the tax benefits of depreciation; and (6) the investment tax credit. The model was developed for evaluating solar energy systems located at the point where the energy is demanded. However, the methodology also has applicability to many other types of energy systems.

Industrial Innovations And Management Toward More Efficient Usage Of Electrical Energy, Tom Day
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
This paper deals with some of the industrial accomplishments in alleviating energy supply and demand problems. A survey is presented on how electrical energy in America is generated, resources used and kilowatt usage for the years 1970 to and including 1974. Conservation of electrical energy is the main theme in which three primary areas of innovation and utilization of industrial equipment are discussed; induction, lighting, heating and air conditioning. An awareness of natural gas shortages and the trend toward an "electric economy" are reviewed. The real challenge to energy management is apparent in order to handle the greatest expansion in …

This system utilizes approximately 13 million tons of lignite and 17,000 acre feet of water per year and consumes 6500 tons of oxygen per day. The results of the study indicate that the major gaseous effluent is CO2, that the federal limits on SO2 effluent may be met, and that the atmospheric degradation criterion will be the most difficult one …
Natural Resource Pricing And Economic Development, Vaman Rao
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.

The paper presents several approaches to the conservation of energy in this area with the use of closed-loop computer control and optimization.
Creating The Electric Energy Economy, L. G. Hauser
Creating The Electric Energy Economy, L. G. Hauser
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
My remarks will be directed to four points:
First, that energy is the life blood of our economy, and that its use or conservation is far from a simple matter of personal habits of waste or frugality. In other words, the vital role energy plays in the production of goods and services should be distinguished from its use in their consumption.
Second, that our excessive dependence on our two scarcest energy resources -- oil and natural gas -- is the core of the energy problem, both U.S. and worldwide.
Third, that limiting our time horizon to this winter, next summer, …
Centralized Solar Wind Home Heating, Russell Peterson, Duane Cromack
Centralized Solar Wind Home Heating, Russell Peterson, Duane Cromack
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
In the immediacy of national goals for energy independence, the need emerges to use dialectic methods to diminish the energy consumptive characteristics of the typical home.
At the cutting edge of resourceful progress are the residential developments which embrace alternative and conservative energy techniques. In conjunction with such a planned, low impact community, this paper proposes a cluster-centralized system which utilizes wind energy in combination with solar thermal energy for space and domestic water heating.
A description of the random solar-wind resource embodies a matching problem that in turn reveals the benefits of the combined mode of energy collection. Though …
Energy And Transportation Policy, James S. Sagner
Energy And Transportation Policy, James S. Sagner
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
Energy shortages of recent years suggest a re-examination of national transportation policy. The lack of a coordinated approach to the solution of urban cogestion inhibits potential short-run responses to gasoline shortfalls. Longer-range policy, particularly in the context of severe financial constraints, must be carefully integrated with demonstrated patterns of urban travel and population and employment densities. Given these considerations, metropolitan areas now planning or constructing rapid rail facilities may be selecting inappropriate responses to the problem of urban access.
Energy, Environment And Incremental Decision Making, Jeff V. Conopask, Robert R. Reynolds Jr.
Energy, Environment And Incremental Decision Making, Jeff V. Conopask, Robert R. Reynolds Jr.
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
During the late 1960's and early 70's a variety of environmental/energy oriented legislation was enacted by the Congress. The most important of these acts, the National Environmental Protection Act (NEPA), required that environmental impact statements be filed when various private and public activities have a potential for impacting man and his environment. (17) Impact statement requirements go beyond the currently practiced cost/benefit analysis, which is often just a production (direct) impact assessment. Heretofore, indirect or second round economic and social effects of consequence affecting other national goals were seldom counted.

Direct Ac Generation From Solar Cell Arrays, Fernando L. Alvarado, Adel H. Eltimsahy
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
Results of the investigation of the performance of solar cells when directly coupled to a conventional three-phase power network are presented. This approach dissociates the electricity production problem from the electric energy storage problem. Extensive studies of the required power inverter are performed. Preliminary simulation results indicate that ac power outputs of better than 90% of the optimum cell power output can be easily achieved by means of a suitably controlled inverter, thereby justifying the elimination of dc loads or local dc electric energy storage devices. It is also shown that the controlling policy for the inverter must depend on …
Dynamic Simulation For Regional Energy Studies, B. W. Jones, P. M. Moretti, J. H. Mize
Dynamic Simulation For Regional Energy Studies, B. W. Jones, P. M. Moretti, J. H. Mize
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
A series of models has been developed for regional studies of energy supply- demand systems. The models are based on dynamic simulation of components of the system using equations derived from the technical details of the system. The models contain sufficient detail to make in-depth studies and specific recommendations. The final goal is to include all aspects of regional energy systems from native supplies of energy resources to the economic activities of the region.
To develop a comprehensive model, the system has been partitioned into subsystems, so that a detailed model can be made for each subsystem. The detailed model …
How Might Synthetic Fuels From Coal Affect Natural Resources And Environment?, H. J. Plass Jr.
How Might Synthetic Fuels From Coal Affect Natural Resources And Environment?, H. J. Plass Jr.
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
Energy self-sufficiency for the U. S. requires substantially increased use of coal. Direct combustion of coal without adequate environmental controls, as would occur if coal were used as a fuel for homes and offices throughout the country, would result in severe air pollution problems„ Synthetic fuels from coal such as methane, low BTU gas, or hydrogen, when utilized by the homes and businesses as gas or as electricity from gas, will contribute a much smaller amount of air pollution. However, to make these synthetic fuels available, it is necessary to mine more coal than would have to be mined for …
Alcohol Assisted Hydrocarbon Fuels: A Comparison Of Exhaust Emissions And Fuel Consumption Using Steady-State And Dynamic Engine Test Facilities, D. J. Bushnell, J. M. Simonsen
Alcohol Assisted Hydrocarbon Fuels: A Comparison Of Exhaust Emissions And Fuel Consumption Using Steady-State And Dynamic Engine Test Facilities, D. J. Bushnell, J. M. Simonsen
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
This paper presents experimental data which exemplifies the differences in emission level testing on internal combustion engines when dynamic engine tests are used instead of steady-state engine tests. A comparison of the two test methods is made using hydrocarbon fuels with varying amounts of methanol. Emissions measured include the nitric oxides, unburned hydrocarbons and carbon monoxide. Emission levels and fuel consumption are reported for the various volumetric percentages of methanol in the fuel.
Of special significance are the different trends the emission levels establish when subjected to a dynamic engine test as compared to the results for the steady-state tests. …

Are Nuclear Shipments Really Safe?, William A. Brobst
Are Nuclear Shipments Really Safe?, William A. Brobst
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
The transportation of nuclear materials is on the increase. Although nuclear shipments are only a very small fraction of the Nation’s hazardous materials shipments, they attract a great deal of public attention. Shipments of spent nuclear fuel and nuclear wastes are a particular concern.
One of the many fears that people have about nuclear energy is the possibility that a nuclear shipment might somehow go awry and cause a serious public hazard. Primarily, they are worried that a shipment of spent reactor fuel or highly radioactive waste could be involved in a serious rail or highway accident and dump its …

The Assessment Of Environmental Impacts At Nuclear Power Generating Stations, Thomas H. Row, J. R. Mcwherter
UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
The Federal actions that are required with regard to nuclear power stations are the granting of a construction permit and later the issuance of a license to operate the station. Since the Atomic Energy Commission (AEC) is responsible for these actions, the Commission is also responsible for preparation of an environmental statement on the proposed actions. The National Laboratories including the one at Oak Ridge are used as part of the staff in preparing the statements.
The staff makes an independent determination of the plant effluents and their dispersions. The impact of these and plant construction on the environment are …

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy
The purpose of this evaluation is to gather data to determine whether or not radiation during a simulated Loss of Coolant Accident would have any effect upon the coatings being used. Because of the concern in industry regarding the safety of nuclear power generating stations and the strong actions of the various environmentalist clubs and agencies clubs and agencies, the utilities have been required to prove the safety of the power facilities to extraordinary degrees before licensing can be obtained to operate. One of the areas regarding the safety is the necessity of proving that the coatings will remain intact …
