VeraSun Energy Corporation was a leading producer of renewable fuel. Founded in 2001, the company has a fleet of 16 production facilities in eight states, of which one is still under construction. VeraSun Energy is scheduled to have an annual production capacity of approximately 1.64 billion gallons (BGY) of ethanol and more than five million tons of distillers grains by the end of 2008. The company also has begun construction at its Aurora, South Dakota facility to extract oil from dried distillers grains, a co-product of the ethanol process, for use in biodiesel production.

VeraSun markets E85, a blend of 85 percent ethanol and 15 percent gasoline for use in Flexible-Fuel Vehicles (FFVs), directly to fuel retailers under the brand VE85. VeraSun Energy now has approximately 150 VE85 retail locations under contract in more than fifteen states and Washington, D.C..

VeraSun Energy was founded in 2001 with the goal of providing a renewable, home-grown energy source while boosting domestic rural economy and creating a future that includes renewable energy to help benefit the environment and reduce the nation's demand for foreign oil.
