In the next few years, major expansion of the production of ethanol from grain could take place. With current technology and government subsidies, ethanol is economically competitive for use as an automotive fuel. The limiting factor to growth likely will be plant capacity. Projections indicate that annual production capacity could reach two billion gallons in several years (Tyner, and Meekhof, Gill and Tyner). Production of two billion gallons would use 770 million bushels of corn--equivalent to the corn production of Nebraska in recent years.
