U.S. Energy Information Agency numbers show that U.S. production of biodiesel was 68 million gallons in February 2013, up from January’s figures of 66 million gallons. The report goes on to say nearly three-fourths of that production came from the Midwest. All 110 biodiesel refineries throughout the country have an operating capacity of 2.1 billion gallons per year:
