Guide to Biofuels: Glossary

A glossary of terms related to biofuels, focusing on definitions of fuel types, the role of corn ethanol in the United States, and the financial mechanisms and lobbying efforts surrounding ethanol production.

• In the United States, corn is the primary biomass used for biofuels, and corn ethanol receives 75 percent of federal subsidy funds designated for renewable energy.
• The Volumetric Ethanol Excise Tax Credit (VEETC), or blender’s tax credit, provides oil companies with $0.45 cents per gallon for purchasing ethanol to blend with gasoline, costing over $5 billion annually and scheduled to expire at the end of 2010.
• The 'blend wall' refers to the 10 percent limit of ethanol that can be blended into a gallon of gasoline; the ethanol lobby is seeking to increase this to 15 percent because production exceeds demand.
