U.S. ethanol production has grown significantly in recent years. In 2005, 97 ethanol plants in 21 states produced a record 3.904 billion gallons of ethanol—an increase of more than 14 percent over 2004 and up an incredible 139 percent from 2000. (Source: Renewable Fuels Association)
Much of the expansion is due to the dramatic growth of farmer-owned co-ops investing in new ethanol production facilities. According to the Renewable Fuels Association, farmer-owned cooperatives are responsible for the majority of ethanol production capacity since 1990.
