EIA - Biofuels Issues and Trends
"Biofuels is a collective term for liquid fuels derived from renewable sources, including ethanol, biodiesel, and other renewable liquid fuels. This report focuses on ethanol and biodiesel, the most widely available biofuels. From 2009 to the middle of 2012, the U.S. biofuels industry increased its output and prepared to meet an expanded Renewable Fuel Standard (RFS2),1 which requires increasing volumes of biofuels use. In 2011, the biofuels industry transitioned away from tax incentives for non-cellulosic biofuels, which expired at the end of 2011...Ethanol grew from 8 percent of U.S. gasoline consumption by volume in 2009 to nearly 10 percent in 2011 and in the first eight months of 2012. With almost all gasoline in the United States already blended with 10 percent ethanol (E10), the maximum level approved for use in all cars and light trucks, significant increases in domestic consumption of ethanol face a blend wall unless higher percentage ethanol blends can achieve significant market penetration."
