BiomassDevelopment of switchgrass (Panicum virgatum) as a bioenergy feedstock in the United StatesCategory: Biomass - Documnet Type: Journal ArticleA 10-year US Department of Energy-sponsored research program designed to evaluate and develop switchgrass (Panicum virgatum), a native perennial warm-season grass, as a dedicated energy crop is reviewed....

Forage production of cool season pasture grasses as related to irrigationCategory: Biomass - Documnet Type: Journal ArticleA significant portion of the irrigated acreage in the intermountain western U.S. is comprised of cool season grass pastures. Droughts, coupled with increasing demands for limited water supplies in the region, have decreased the water volumes available for irrigating these pastures and other crops.... More» Author: D. Smeal, M.K. O’Neill and R.N. Arnold - submitted on Wed, 09/30/2009 - 15:40. The impact of growing miscanthus for biomass on farmland bird populationsCategory: Biomass - Documnet Type: Journal ArticleMiscanthus is a newly introduced crop grown primarily to produce biomass for energy production and the area grown in the UK is anticipated to increase. Major differences in crop management from conventional arable crops have led to speculation that miscanthus may also have effects on farmland biodiversity.... More» Author: P.E. Bellamy , P.J. Croxtona, M.S. Hearda, S.A. Hinsleya, L. Hulmesa, S. Hulmesa, P. Nuttalla, R.F. Pywella and P. Rotherya - submitted on Wed, 09/30/2009 - 15:30. A Spatial Model to Determine the Economic Availability of Woody Biomass in ColoradoCategory: Biomass - Documnet Type: Technical ReportThe purpose of this paper is to propose a spatial model that can be used as a tool for making decisions regarding the proper sizing of woody biomass projects that require allocating public and private money and resources. This spatial model determines the cost for sustainably extracting and transporting woody biomass from watersheds in Colorado to a specific location....

A Strategic Assessment of Forest Biomass and Fuel Reduction Treatments in Western StatesCategory: Biomass - Documnet Type: Technical ReportThis assessment characterizes, at a regional scale, forest biomass that can potentially be removed to implement the fuel reduction and ecosystem restoration objectives of the National Fire Plan for the Western United States. The assessment area covers forests onboth public and private ownerships in the region and describes all standing tree volumeincluding stems, limbs, and tops....

Use of U.S. Croplands for Biofuels Increases Greenhouse Gases Through Emissions from Land-Use ChangeCategory: Biomass - Documnet Type: Journal ArticleMost prior studies have found that substituting biofuels for gasoline will reduce greenhouse gases because biofuels sequester carbon through the growth of the feedstock. These analyses have failed to count the carbon emissions that occur as farmers worldwide respond to higher prices and convert forest and grassland to new cropland to replace the grain (or cropland) diverted to biofuels....

Beneficial Biofuels—The Food, Energy, and Environment TrilemmaCategory: Biomass - Documnet Type: Journal ArticleRecent analyses of the energy and greenhouse-gas performance of alternative biofuels have ignited a controversy that may be best resolved by applying two simple principles....

Land Clearing and the Biofuel Carbon DebtCategory: Biomass - Documnet Type: Journal ArticleIncreasing energy use, climate change, and carbon dioxide (CO2) emissions from fossil fuels make switching to low-carbon fuels a high priority. Biofuels are a potential low-carbon energy source, but whether biofuels offer carbon savings depends on how they are produced....

Driving on BiomassCategory: Biomass - Documnet Type: Journal ArticleThe development of the internal combustion engine (ICE) vehicle dramatically influenced American society during the 20th century by providing affordable, reliable transportation. However, the ICE vehicle is an inherently inefficient converter of chemical energy to mechanical power; less than 20% of the energy in gasoline is transformed into mechanical work, and the remainder is lost as heat....

Carbon-Negative Biofuels from Low-Input High-Diversity Grassland BiomassCategory: Biomass - Documnet Type: Journal ArticleBiofuels derived from low-input high-diversity (LIHD) mixtures of native grassland perennials can provide more usable energy, greater greenhouse gas reductions, and less agrichemical pollution per hectare than can corn grain ethanol or soybean biodiesel. High-diversity grasslands had increasingly higher bioenergy yields that were 238% greater than monoculture yields after a decade....
