U.S. ethanol production has increased rapidly since 2006, reaching about 13.95 billion gallons in 2011 (Table 1). The increase was driven by a combination of high crude oil prices, federal Renewable Fuel Standards (RFS) for domestic renewable fuel consumption, a generous tax credit for ethanol blenders, and large net exports in 2010 and 2011. The expansion in domestic ethanol production has been one of the main drivers of the corn market since 2006, as corn is the primary feedstock for ethanol production in the U.S. The USDA estimates that corn processed for ethanol production totaled 5.021 billion bushels in the 2010-11 marketing year and projects use at 5 billion bushels for the current marketing year.
