Analysis of energy use in building services of the industrial sector in California: A literature review and a preliminary characterization

Description: Energy use patterns in many of California's fastest-growing industries are not typical of those in the mix of industries elsewhere in the US. Many California firms operate small and medium-sized facilities, often in buildings used simultaneously or interchangeably for commercial (office, retail, warehouse) and industrial activities. In these industrial subsectors, the energy required for building services'' to provide occupant comfort and necessities (lighting, HVAC, office equipment, computers… more

TRANSIENT RADIATION EFFECTS IN CAPACITORS AND DIELECTRIC MATERIALS

Description: Measurements of dielectric leakage, capacitance, electric strength, andd charge scattering phenomena were performed at the Kukla and Godiva III critical assemblies for tantalum and aluminum electrolytic, wax- and oilimpregnated paper, mylar, mica, and ceramic capacitors, and for mylar and Vitamin B-impregnated paper. Leakage data indicate that gamma induced conductivity in capacitor dielectric varies directly with gamma DELTA , where gamma is the gamma radiation rate and DELTA is 0.9 for mylar,… more

Impacts of the national energy programme on solar economics

Description: The National Energy Plan (NEP) sets as a goal the use of solar energy in two and a half million homes in 1985. A key provision of the NEP (as well as congressional alternatives) provides for the subsidization of solar equipment. The extent to which these subsidies (income tax credits) might offset the impact of continued energy-price control is examined. Regional prices and availability of conventional energy sources (oil, gas, and electricity) were compiled to obtain a current and consistent s… more

Technology trends in econometric energy models: Ignorance or information

Description: Simple time trend variables in factor demand models can be statistically powerful variables, but may tell the researcher very little. Even more complex specification of technical change, e.g. factor biased, are still the economentrician's measure of ignorance'' about the shifts that occur in the underlying production process. Furthermore, in periods of rapid technology change the parameters based on time trends may be too large for long run forecasting. When there is clearly identifiable engine… more

RESFEN: A residential fenestration performance design tool

Description: This paper describes the development of a prototype PC-based computer program called RESFEN. The program calculates the heating and cooling energy performance and costs of residential fenestration systems. Regression analysis of a data base of DOE-2 building energy simulations of single- and two-story residential buildings was used to develop algrbraic expressions that form the basis of the calculation procedure. The user can vary geographic location, electricity and gas cost, infiltration and … more

A tritium-compatible piezoelectric valve for the tokamak fusion test reactor

Description: This work describes modifications made to a commercial piezoelectric valve to make it sufficiently tritium compatible for the TFTR trritium injection scenario. The results of testing the valve for leakage and performance following a series of progressively more severe tritium exposures are also presented. Finally, a proposal for a totally radiation-compatible piezoelectric valve, suitable for tritium-burning fusion machines of the future, is decribed. 9 refs., 2 figs., 1 tab.

1992 Conversion Resources Supply Document

Description: In recent years conservation of electric power has become an integral part of utility planning. The 1980 Pacific Northwest Electric Power Planning and Conservation Act (Northwest Power Act) requires that the region consider conservation potential in planning acquisitions of resources to meet load growth. The Bonneville Power Administration (BPA) developed its first estimates of conservation potential in 1982. Since that time BPA has updated its conservation supply analyses as a part of its Reso… more

Potential minimum cost of electricity of superconducting coil tokamak power reactors

Description: The potential minimum cost of electricity (COE) for superconducting tokamak power reactors is estimated by increasing the physics (confinement, beta limit, bootstrap current fraction) and technology (neutral beam energy, toroidal field (TF) coil allowable stresses, divertor heat flux, superconducting coil critical field, critical temperature, and quench temperature rise) constraints far beyond those assumed for ITER until the point of diminishing returns is reached. A version of the TETRA syste… more

Economy of a retrofit solar system

Description: A privately financed solar-augmented hot water system has been demonstrated to pay off in less than 10 years if a loan is obtained at 10.5% interest. Calculations were made on the assumption that electricity costs 5 cents per kWh and water consumption averages 30 gallons per day (using current technology on an existing dwelling in Tennessee).

Model for the crosscoupling parameters of rocks

Description: The self-potential method of geothermal exploration is based on the measurement of naturally occurring electrical potentials generated by flows of fluid (electrokinetic) and heat (thermoelectric) through rocks. The interpretation of self-potential measurements by modeling requires a knowledge of crosscoupling parameters of geological materials. In general there is a paucity of such data and one of the largest compilations of crosscoupling parameters consists of data on only 40 samples. Much mor… more

Alternatives to compressor cooling in California climates

Description: This review and discussion has been prepared for the California Institute for Energy Efficiency (CIEE) to examine research on alternatives to compressor cooling. The report focuses on strategies for eliminating compressors in California's transition climates -- moderately warm areas located between the cool coastal regions and the hot central regions. Many of these strategies could also help reduce compressor use in hotter climates. Compressor-driven cooling of residences in California's transi… more

Estimated increases in the cost of electricity under three acid-rain control bills

Description: Several bills were introduced in the past two Congresses to reduce emissions of sulfur dioxide and nitrogen oxides from electric power plants. The effects of these bills on electricity costs depend on features of the bills, on the mix of generating capacity owned by different electric utilities, on the technologies available for complying with the legislation, and on the time horizon used to calculate the costs. A system of computer software has been developed to make utility-specific estimates… more

Manufacturing fuel-switching capability, 1988

Description: Historically, about one-third of all energy consumed in the United States has been used by manufacturers. About one-quarter of manufacturing energy is used as feedstocks and raw material inputs that are converted into nonenergy products; the remainder is used for its energy content. During 1988, the most recent year for which data are available, manufacturers consumed 15.5 quadrillion British thermal units (Btu) of energy to produce heat and power and to generate electricity. The manufacturing … more

Analysis and technology transfer report, 1989 and 1990

Description: The buildings sector used 29.6 quadrillion Btus (quads) of energy in 1989, or 36 percent of the total primary energy consumed in the United States. The major uses are for space heating and cooling, water heating, refrigeration, and lighting. Electricity is the dominant fuel, followed by natural gas, petroleum, and other fuels. Although there were dramatic improvements in energy efficiency in this sector from 1975 to 1985, in recent years energy use has grown rapidly. The large growth expected i… more

Physical Impacts of Climate Change on the Western US Electricity System: A Scoping Study

Description: This paper presents an exploratory study of the possible physical impacts of climate change on the electric power system, and how these impacts could be incorporated into resource planning in the Western United States. While many aspects of climate change and energy have been discussed in the literature, there has not yet been a systematic review of the relationship between specific physical effects and the quantitative analyses that are commonly used in planning studies. The core of the proble… more
