Bioenergy Crop Production in the United States: Potential Quantities, Land Use Changes, and Economic Impacts on the Agricultural Sector

The U.S. Departments of Agriculture and Energyjointly analyzed the economic potential for,and impacts of, large-scale bioenergy cropproduction in the United States. Anagricultural sector model (POLYSYS) wasmodified to include three potential bioenergycrops (switchgrass, hybrid poplar, and willow). At farmgate prices of US

Supply and Social Cost Estimates for Biomass from Crop Residues in the United States

2.44/GJ, anestimated 17 million hectares of bioenergycrops, annually yielding 171 million dry Mg ofbiomass, could potentially be produced at aprofit greater than existing agricultural usesfor the land. The estimate assumes highproductivity management practices are permittedon Conservation Reserve Program lands. Traditional crops prices are estimated toincrease 9 to 14 percent above baseline pricesand farm income increases annually by US

The Energy Balance of Corn Ethanol: An Update

1.83/GJ, anestimated 7.9 million hectares of bioenergycrops, annually yielding 55 million dry Mg ofbiomass, could potentially be produced at aprofit greater than existing agricultural usesfor the land. The estimate assumes managementpractices intended to achieve highenvironmental benefits on Conservation ReserveProgram lands.

The components of social costsincluded in the supply analysis are cashoutlays and opportunity costs associated withharvest and alternative residue uses, potentialenvironmental damage that is avoided byexcluding unsuitable land, and costs in movingresidues from farms to processing plants. Regional estimates account for the growingconditions and crops of the main agriculturalareas of the United States. Estimates includethe main U.S. field crops with potential forresidue harvest: corn, wheat, sorghum, oats,barley, rice and cane sugar. The potentialcontribution of residues to U.S. energy needsis discussed.

Plant size: Capital cost relationships in the dry mill ethanol industry

The effects of likely regulatory and policy changes in the US gasoline and additives market are compared to a reference baseline. The baseline reflects existing EPA policies about fuel quality regulation and likely petroleum and gasoline expansions. The market and welfare effects are presented for implementing a renewable fuel standard; imposing a national ban on the additive MTBE; and removing the oxygen standard for reformulated fuel. Market and welfare estimates are based on adjusting product market demands and factor supplies. Product market and price analyses include quality-differentiated products, such as refinery gasoline, chemical additives and ethanol at the wholesale level; and gasoline grades in conventional, reformulated and oxygenated markets at the ratail level. Factor market analyses include supplies for petroleum, natural gas byproducts, and corn. The analysis includes the welfare cost of fuel to consumers and income in agriculture and the petroleum sector.
