We often hear proponents of the federal Renewable Fuel Standard (RFS) argue that mandating increasing use of ethanol in the nation’s fuel supply is about consumer choice. This view is reflected in some of the news coverage of this week’s RFS public hearing in Kansas City.
Yet, when you look at the marketplace and the fuels consumers actually want, the RFS represents restricting choice, not expanding it.

To understand why the Renewable Fuel Standard (RFS) must be repealed or significantly reformed, start at the “blend wall.”
The ethanol blend wall is where – because of the RFS’ mandates – more ethanol must be blended into the nation’s fuel supply than can be absorbed as E10 gasoline – gasoline containing up to 10 percent ethanol, which is standard across the country. Put another way, when ethanol makes up more than 10 percent of the total U.S. fuel mix, you’ve breached the blend wall.
At that point refiners have few options. They can produce E15 and E85, fuels containing higher volumes of ethanol, or they can comply with the RFS by reducing the amount of fuel supplied to the domestic market. Neither is a good choice for American consumers.
