(EIA) Biofuels Issues and Trends
This report addresses the ethanol and biodiesel markets separately, reviewing recent trends (January
2009 to August 2012) in consumption, production and feedstock inputs, imports, exports, prices and
producer margins, and infrastructure. The discussion of consumption issues is framed in terms of the volume percentage of ethanol in gasoline and biodiesel in diesel fuel and heating oil. Volume percentages are important because engines and other equipment may be limited in their ability to use ethanol or biodiesel in proportion to the amount of petroleum used. This is particularly true in the case of fuel ethanol, which now constitutes nearly 10 percent by volume of every gallon of gasoline sold in the United States.
