This simple assessment raster is used to answer management questions (MQs) about where change agents (CAs) overlap with BLM high biodiversity sites (HBS) in the Central Great Basin and Range Ecoregion. This is a basic footprint assessment of anthropogenic features (urban development, roads, etc) intersect with the areas of HBS. The HBS were derived from source data characterizing locations with concentrated at-risk biodiversity or existing source data of a prioritization exercise that identified areas of high conservation significance. It does not model actual response or condition of the HBS to the CAs. The data intersects two primary classes of information: The CAs consist of 19 classes which represent different...
This assessment raster is used to answer management questions (MQs) about where the Desert Tortoise conservation element (CE) overlap with change agents (CAs). This is a basic footprint assessment of anthropogenic features (urban development, roads, etc). It does not model actual response of the CEs to the CAs; those more complex issues are addressed in different MQs and through different models.

Some types are easily defined, precise footprints (pipelines, roads, energy development areas) while others are broader...
Over the 1970s and 1980s, emissions of carbon dioxide from energy use fell in per capita, per unit GDP, and in some cases in absolute terms in 10 industrialized countries studied by LBNL. These declines were driven principally by falling end-use energy intensities and the decreasing carbon content of energy. By the early 1990s, however, a slowdown in the decline of intensities and the continued growth of GDP and energy services activity have reversed the trends in absolute emissions. LBNL concludes that CO2 emissions will continue to rise in the future unless energy intensities and/or the carbon content of energy can be decreased at an accelerated rate via policy changes, technological innovation and/or behavioural...
In order to promote the production and use of electricity generated from renewable energy sources, support schemes such as the Renewables Portfolio Standard and various green power programs have been implemented. When evaluating the costs and benefits associated with those schemes, people need accurate information about the characteristics of renewable generation. The objective of the present paper is to identify the kind of information to be provided to lay people in Japan in order to enhance their understanding of biomass generation. We used the two-stage "mental model" method to conduct open-ended interviews and a questionnaire survey to reveal people's beliefs about biomass generation. From the survey results,...
High-temporal resolution meteorological output from the Parallel Climate Model (PCM) is used to assess changes in wildland fire danger across the western United States due to climatic changes projected in the 21st century. A business-as-usual scenario incorporating changing greenhouse gas and aerosol concentrations until the year 2089 is compared to a 1975 - 1996 base period. Changes in relative humidity, especially drying over much of the West, are projected to increase the number of days of high fire danger ( based on the energy release component (ERC) index) at least through the year 2089 in comparison to the base period. The regions most affected are the northern Rockies, Great Basin and the Southwest - regions...
This raster is used to answer management questions (MQs) about where conservation elements (CEs) overlap with areas of high solar energy potential in the Central Basin and Range Ecoregion. The value indicated in the raster represents a normalized score between 0-1, the lower the value the few species and poorer modeled landscape condition (ecological integrity) expected. The higher the score, the more species and higher condition are expected. This layer seeks to address an article in the BLM Statement of Work 1.1.1 stated, Areas with High Potential for Renewable Energy Development (Required) (The Contractor shall a) locate areas identified (e.g., by DOE, USGS) as suitable for wind, solar, geothermal, and biomass...

The Habitat Evaluation Procedures (HEP) were used to evaluate pre- and postconstruction habitat conditions of the U.S. Army Corps of Engineers Bonneville project in Oregon and Washington. The project directly impacted 20,749 acres of wildlife habitat. Seven evaluation species were selected with losses and gains expressed in Habitat Units (HU's). One HU is equivalent to 1 acre of prime habitat. The evaluation estimated a gain of 2,671 HU's of lesser scaup wintering habitat. Losses of 4,300 HU's of great blue heron habitat, 2,443 HU's of Canada goose habitat, 2,76? HU's of spotted sandpiper habitat, 163 HU's of yellow warbler habitat, 1,022 HU's black-capped chickadee habitat, and 1,622 HU's of mink habitat occurred...

Carbon Capture and Storage (CCS) is a critical part of the global effort to address climate change as CCS has the potential to achieve deep cuts in CO2 emissions to atmosphere from the use of fossil fuels. In this context, pre-combustion capture through Integrated Gasification Combined Cycle (IGCC) power plants with CCS is one of the key pathways to low emissions power generation. There are, however, very significant challenges to the development, commercialization and deployment of IGCC with CCS technologies. This article examines matters of cost, the need for government support to early movers, the attribution of economic value for carbon dioxide and various other regulatory, policy, technical and infrastructural...
Societal dependence on oil leads to increasingly negative social consequences throughout the world, including climate change, air pollution, political and economic instability, and habitat degradation. Reliance on the automobile for transportation also contributes to a sedentary lifestyle, an obesity epidemic and poor health. These problems are particularly pronounced in the USA, which currently consumes c. 27% of global oil production and produces c. 25% of global carbon emissions, and where c. 65% of adults are overweight or obese. Other countries throughout the world that replicate or hope to replicate the automobile-based lifestyle of the USA face similar problems now or in the near future. This paper develops...
In February 1983, the U.S. Department of Energy (DOE) identified the Yucca Mountain site in Nevada as one of nine potentially acceptable sites for a mined geologic repository for spent nuclear fuel and high-level radioactive waste. The site is in the Great Basin, which is one of five distinct geohydrologic settings considered for the first repository. To determine their suitability, the Yucca Mountain site and the eight other potentially acceptable sites have been evaluated in accordance with the DOE'S General Guidelines for the Recommendation of Sites for the Nuclear Waste Repositories. These evaluations were reported in draft environmental assessments (EAs), which were issued for public review and comment. After...

Post-combustion CO2 capture and storage (CCS) presents a promising strategy to capture, compress, transport and store CO2 from a high volume-low pressure flue gas stream emitted from a fossil fuel-fired power plant. This work undertakes the simulation of CO2 capture and compression integration into an 800 MW supercritical coal-fired power plant using chemical process simulators. The focus is not only on the simulation of full load of flue gas stream into the CO2 capture and compression, but also, on the impact of a partial load. The result reveals that the energy penalty of a low capture efficiency, for example, at 50% capture efficiency with 10% flue gas load is higher than for 90% flue gas load at the equivalent...

Most countries now wish to reduce their dependence on fossil fuels. In this paper, Professors Häfele and Manne discuss transition away from the current situation where virtually all demands for primary energy are met by fossil fuels. Assuming that this transition is to be based upon nuclear fission, they examine the interplay between natural resource scarcities, economics costs and the assessment of alternative technologies for the production of synthetic fuels.

This model provides one view of ecological integrity for the ecoregion, based on a model of landscape condition, which has been summed into the 4x4km grid cells. Anthropogenic stressors come in many forms, from regional patterns of acid deposition or climate-induced ecosystem change, to local-scale patterns in agricultural drainage ditches and tiles, point-source pollution, land-conversion, and transportation corridors, among others. To be effective, a landscape condition model needs to incorporate multiple stressors, their varying individual intensities, the combined and cumulative effect of those stressors, and if possible, some measure of distance away from each stressor where negative effects remain likely....

This data is a model of potential habitat connectivity for the Mojave desert tortoise (Gopherus agassizii) for the Mojave Basin and Range ecoregion. Methods for developing this data set: The connectivity modeling software Circuitscape 3.5.7 was used to develop the desert tortoise model. The two inputs needed to model tortoise habitat connectivity with this software were developed in ArcGIS 10. Habitat Input: The USGS model for desert tortoise habitat potential was used to create a series of 167 points representing tortoise habitat throughout the Mojave Basin and Range ecoregion. Areas with high habitat potential (0.7 or higher) were selected and converted to polygons. Polygons smaller than 4,000 acres were removed....
