An expected increase in ethanol blending and expanding U.S. refinery operations will cut the country's foreign gasoline requirements in 2012 to below 400,000 barrels per day by 2012, compared with about 1 million barrels per day in 2008, according to a report from Energy Security Analysis. "The volume of ethanol blending in the United States has moved from something that is a relatively small amount to something that is a substantial and very real part of mainstream fuels," said Sander Cohan, an executive at ESAI.
