Estimates of the number of large amplitude gusts

Description: Preliminary estimates are presented of the number of occurrences of large amplitude gusts for use in the design of wind energy conversion systems. Existing turbulence information has been combined with an assumed wind speed distribution to arrive at the estimates. The number of large amplitude gusts per year is treated as a function of the annual mean wind speed and terrain roughness. This treatment is based upon the assumptions that the atmosphere has neutral stability during high winds and th… more

Technical-economic assessment of the production of methanol from biomass. Executive summary. Final research report

Description: The results are presented of a comprehensive systems study which assessed the engineering and economic feasibilities of the production of methanol from biomass utilizing existing technology. The three major components of the biomass to methanol system assessed are the availability of biomass feedstocks, the thermochemical conversion of biomass to methanol fuels, and the distribution and markets for methanol fuels. The results of this study show that methanol fuel can be produced from biomass us… more

California solar data manual

Description: Factors that determined the data contents of the manual are presented. Estimates of errors in the data are provided, and the impact of these errors on solar design is discussed. The state is divided into 15 solar zones of roughly similar solar radiation conditions, which are illustrated along with page references to the most relevant solar and climate data. A guide to the data tables and graphs is provided, which are displayed under solar, climate, and sky charts. A guide is given to simplified… more

Crop residues as a fuel for power generation

Description: Crop residues could serve as an alternative energy source for producing electric power and heat in agricultural regions of the United States. Nearly 2 quads of residues are estimated to be available as a sustainable annual yield. These can substitute for up to one quad of conventional fuels used to generate electricity and up to an additional quad of petroleum and natural gas currently used for producing heat. The most promising routes to residue conversion appear to be regional generators size… more

National hydroelectric power resources study. Preliminary inventory of hydropower resources. Volume 6. Northeast region

Description: In the Northeast region, the physical potential for all sites exceeds 33,000 MW of capacity with an estimated average annual energy of some 153,000 GWH. By comparison, the available data represent about 6% of the total capacity and 11% of the hydroelectric energy potential estimated for the entire US. Of the total capacity estimated for the region, 6100 MW has been installed. The remainder (27,200 MW, excluding the undeveloped capacity in the New England States) is the maximum which could be de… more

Potential geothermal resources in Hawaii: a preliminary regional survey. Phase I, final report

Description: A regional geothermal resource assessment has been conducted for the major islands in the Hawaiian chain. The assessment was made through the compilation and evaluation of the readily accessible geological, geochemical, and geophysical data for the Hawaiian Archipelago that have been acquired during the last two decades. The geologic criteria used in the identification of possible geothermal reservoirs were age and location of most recent volcanism on the island and the geologic structure of ea… more

Effect of generalized wind characteristics on annual power estimates from wind turbine generators

Description: A technique is presented for estimating the average power output of a wind turbine using, as the wind characteristic input, only the mean annual wind magnitude. Hourly wind speeds are assumed to have a Rayleigh frequency distribution which requires a single parameter input (e.g., the mean value, variance or higher moment values). Based upon a general shape, for the wind speed versus machine output, a generic set of curves is developed to estimate the average power output of wind turbines. Also,… more

Relative availability of selected trace elements from coal fly ash and Lake Michigan sediment

Description: The concentration of greater than 1 ..mu..m coal fly ash particles in Lake Michigan surface waters was found to be 10/sup 5/ to 10/sup 6/ per liter. With an expected residence time of one year, this concentration implies a flux to the sediment of 10/sup 6/ to 10/sup 7/ particles/cm/sup 2//yr, or about 10/sup -6/ to 10/sup -5/ g/cm/sup 2//yr. The release of trace elements from fly ash and sediment has been studied using Chelex-100 resin to simulate leaching at high dilutions in natural media. Mn… more

Preliminary definition of the geothermal resources potential of Pennsylvania

Description: Pennsylvania has a diverse geology. A small portion of the northeastern corner of the state is covered by Atlantic Coastal Plains sediments. To the northwest metamorphic rocks in the Piedment, Blue Ridge and Reading Prong areas are exposed. Triassic basine cut across portions of the Piedmont. The western portion of the state is underlain by Paleozoic sediments of the folded Appalachians and the Appalachian or Allegheny Basin. Crystalline rocks are limited to the metamorphic and igneous rocks of… more

National hydroelectric power resources study. Preliminary inventory of hydropower resources. Volume 2. Pacific Southwest region

Description: The estimates of existing, incremental, and the undeveloped hydropower potential for all states in the various regions of the country are presented. In the Pacific Southwest region, the maximum physical potential for all sites exceeds 33,000 MW of capacity with an estimated average annual energy greater than 85,000 GWH. By comparison, these values represent about 6% of the total potential capacity and hydroelectric energy generation estimated for the entire US. Of the total capacity estimated f… more

National hydroelectric power resources study. Preliminary inventory of hydropower resources. Volume 4. Lake Central region

Description: The estimates of existing, incremental and the undeveloped hydropower potential for all states in the various regions of the country are presented. In the Lake Central region, the maximum physical potential for all sites exceeds 26,000 MW with an estimated average annual energy of more than 75,000 GWH. By comparison, these values represent about 5% of both the total potential capacity and hydroelectric energy estimated for the entire US. Of the total capacity estimated for the region, 2600 MW h… more
