For more than 10 years, the Renewable Fuel Standard (RFS) has been gradually changing the U.S. fuel supply, injecting more biofuels and corn ethanol into our gasoline every year. Under the policy, America’s corn ethanol industry has matured. Corn ethanol will account for 15 billion gallons of the fuel supply this year; it is the preferred octane booster in gasoline and is in high demand as an international export.

In fact, for seven years, the United States has been a net exporter of ethanol fuel.
