Evaluating The Total Cost Of An On-Site Solar Energy System, Dennis Costello, Jerry Bradley Oct 1975

Evaluating The Total Cost Of An On-Site Solar Energy System, Dennis Costello, Jerry Bradley

UMR-MEC Conference

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.


Self-Consistency In Estimating Future Electrical Energy Consumption, W. D. Devine Jr., C. C. Calligan, O. D. Osborne Oct 1975

Self-Consistency In Estimating Future Electrical Energy Consumption, W. D. Devine Jr., C. C. Calligan, O. D. Osborne

UMR-MEC Conference

A socio economic computer simulation model for the State of Oregon is described. The Oregon State Simulation Model (OSSIM) includes a thirty-seven sector model of electrical energy consumption. Coupling between this model and the OSSIM ensures self-consistent scenarios of socio economic phenomena which underlie energy consumption. One of the purposes of this effort is to help state-level decision makers understand the determinants of electricity consumption within a context of changing economic conditions.


The Design And Application Of Induction Motors For Efficient Energy Utilization, Paul K. Lindhorst Oct 1975

The Design And Application Of Induction Motors For Efficient Energy Utilization, Paul K. Lindhorst

UMR-MEC Conference

The various means for increasing electric motor efficiency and power factor are presented from the design and application points of view. Various design options are explored using computer aided design procedures. Motor characteristics are reviewed with the intent of maximizing efficiency through proper application. A thorough study of the economics of higher efficiency motors is presented showing payback to the user in terms of energy cost savings and payback of the increased energy required to produce the higher efficiency motors.


Industrial Innovations And Management Toward More Efficient Usage Of Electrical Energy, Tom Day Oct 1975

Industrial Innovations And Management Toward More Efficient Usage Of Electrical Energy, Tom Day

UMR-MEC Conference

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 ...


Dynamic Simulation For Regional Energy Studies, B. W. Jones, P. M. Moretti, H. H. Mize Oct 1975

Dynamic Simulation For Regional Energy Studies, B. W. Jones, P. M. Moretti, H. H. Mize

UMR-MEC Conference

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 ...


Optimum Control Of Heating, Ventilating And Air Conditioning Systems, Terry R. Weaver Oct 1975

Optimum Control Of Heating, Ventilating And Air Conditioning Systems, Terry R. Weaver

UMR-MEC Conference

The control of HVAC systems has traditionally been performed by relatively simple field hardware. The industry appears, however, to be ready for the use of more sophisticated measures. The paper presents several approaches to the conservation of energy in this area with the use of closed-loop computer control and optimization.


An Engineering, Geological And Hydrological Environmental Assessment Of A 250 Mmscfd Dry Ash Lurgi Coal Gasification Facility, Mason H. Somerville, James L. Elder, Stephen R. Moran Oct 1975

An Engineering, Geological And Hydrological Environmental Assessment Of A 250 Mmscfd Dry Ash Lurgi Coal Gasification Facility, Mason H. Somerville, James L. Elder, Stephen R. Moran

UMR-MEC Conference

A preliminary engineering, geological, and hydrological environmental assessment of a proposed 250 MMSCFD dry ash Lurgi coal gasification facility is discussed.

The facility's emission spectrum is examined on the basis of the proposed design and empirical data. 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 ...


How Might Synthetic Fuels From Coal Affect Natural Resources And Environment?, H. J. Plass Jr. Oct 1975

How Might Synthetic Fuels From Coal Affect Natural Resources And Environment?, H. J. Plass Jr.

UMR-MEC Conference

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 ...


Correlation Of Theory And Experiment For The Dynamics Of A Pressurized Water Reactor, J. G. Thakkar Mar 1975

Correlation Of Theory And Experiment For The Dynamics Of A Pressurized Water Reactor, J. G. Thakkar

Masters Theses

Dynamic tests were performed on the Carolina Power and Light Company's H. B. Robinson Unit 2 to determine the frequency response of the PWR steam supply system. Step inputs and multi-frequency binary signals of various sequence lengths and bit durations were used. The signals were introduced manually by the operator both for reactivity perturbation and steam flow perturbation tests. The experimental results were analyzed on and IBM 360/65 computer. The test results were compared with theoretical results predicted by a mathematical model of the system.

A mathematical model for the H. B. Robinson system was formulated. In most ...


Creating The Electric Energy Economy, L. G. Hauser Jan 1975

Creating The Electric Energy Economy, L. G. Hauser

UMR-MEC Conference

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, or ...
