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

Energy and water consumption of Pacific Northwest irrigation systems

Description: Irrigation in the Pacific Northwest is an energy-intensive process which represents a major part of the total energy used in farm level food production. Since 1950, several major developments have precipitated pronounced increases in irrigation energy requirements. For example, the invention of efficient high-lift pumps, labor-saving equipment, new uses for irrigation sprinklers, and profitable cropping patterns have substantially escalated irrigation energy consumption in the Pacific Northwest… more

Analysis of the response of the Raft River monitor wells to the 1979 injection tests

Description: The geothermal resource for the Department of Energy's (DOE) Raft River Geothermal 5 MWe Power Project is located in a closed ground water basin in southcentral Idaho. Chemical analyses indicate the existence of natural communication along fractures between the geothermal reservoir and the shallower aquifers developed for irrigation. Much of the ground water that is presently used for irrigation is of poor quality. Injection of geothermal fluids at intermediate depths may increase communication… more

Assessment of geothermal development in the Imperial Valley of California. Volume 1. Environment, health, and socioeconomics

Description: Utilization of the Imperial Valley's geothermal resources to support energy production could be hindered if environmental impacts prove to be unacceptable or if geothermal operations are incompatible with agriculture. To address these concerns, an integrated environmental and socioeconomic assessment of energy production in the valley was prepared. The most important impacts examined in the assessment involved air quality changes resulting from emissions of hydrogen sulfide, and increases in th… more

Irrigation data base for Arizona

Description: Determining the locations in the U.S. where solar energy might be used for irrigation was proposed. One of the first steps in determining these locations is to establish a data base for the agricultural states that extensively use irrigation. The data base must include information on the crops grown, the irrigation wells, and the irrigation pumps. The results of an effort to establish such a data base for the state of Arizona are presented.

Energy sensitivity and variability analysis of Populus hybrid short-rotation plantations in northeastern United States. Final report

Description: Production of biomass by corn-like plantations has been demonstrated by a number of researchers. These forest analogs of agronomic cropping systems have the potential to yield substantially more biomass per unit area than traditional forests. Care is needed in choosing the appropriate sites, species, spacing, and harvesting strategies. Opportunities for increased yields have been suggested for fertilization and irrigation. Utilization of the biomass from these dense plantations for energy was t… more

Analysis of the research and development effort in the private sector to reduce energy consumption in irrigated agriculture

Description: Manufacturers of irrigation equipment perform research and development in an effort to improve or maintain their position in a very competitive market. The market forces and conditions that create the intense competition and provide incentive for invention are described. Particular emphasis is placed on the market force of increased energy costs, but the analysis is developed from the perspective that energy is but one of many inputs to agricultural production. The analysis is based upon publis… more

Update to the Ground-Water Withdrawals Database for the Death Valley REgional Ground-Water Flow System, Nevada and California, 1913-2003

Description: Ground-water withdrawal estimates from 1913 through 2003 for the Death Valley regional ground-water flow system are compiled in an electronic database to support a regional, three-dimensional, transient ground-water flow model. This database updates a previously published database that compiled estimates of ground-water withdrawals for 1913–1998. The same methodology is used to construct each database. Primary differences between the 2 databases are an additional 5 years of ground-water withdra… more

Atmospheric Climate Model Experiments Performed at Multiple Horizontal Resolutions

Description: This report documents salient features of version 3.3 of the Community Atmosphere Model (CAM3.3) and of three climate simulations in which the resolution of its latitude-longitude grid was systematically increased. For all these simulations of global atmospheric climate during the period 1980-1999, observed monthly ocean surface temperatures and sea ice extents were prescribed according to standard Atmospheric Model Intercomparison Project (AMIP) values. These CAM3.3 resolution experiments serv… more

Influence of irrigation and weathering reactions on the composition of percolates from retorted oil shale in field lysimeters

Description: Major cations, anions, trace elements and dissolved organic C were measured in percolate from retorted oil shale collected from irrigated lysimeters in the field at Anvil Points, Colorado, over a two year period. The investigations indicated that chemical equilibrium was not established over the monitoring period and major changes occurred in percolate composition as a function of applied water volume and water residence time in the shale. Field and laboratory studies indicated that several fac… more

DSM pocket guidebook

Description: It has been estimated that if electricity were used more efficiently with commercially available end-use technologies, 24%--44% of the nation's current demand for electricity could be eliminated. Almost all major electric utilities in the west are investigating such demand-side management (DSM) opportunities. In some service territories, for example, improved efficiency could soon produce as much power as that from new coal-fired plants and produce it at a lower cost. Even utilities that curren… more

Simulation of the long-term accumulation of radiocontaminants in crop plants

Description: Most radiological dose assessment models ignore the long-term buildup of radiocontaminants in the soil. When they estimate levels in crop plants from root uptake, these models account only for the annual input from the source into the soil. Almost all of the models ignore the build-up of contaminants in the soil profile due to the accumulation in the roots and the build-up from the above-ground plant material that is buried by plowing. The model described in this report simulates the entire sys… more
