President-elect Donald Trump cruised to victory promising to get rid of the mandate to buy health insurance. While he’s at it, how about getting rid of the mandate to buy ethanol?
The federal government mandates that virtually all gasoline include ethanol, known as the Renewable Fuel Standard. The Environmental Protection Agency, which oversees the ethanol program, recently released its 2017 guidelines for increased ethanol usage, calling for nearly 19 billion gallons of renewable fuel — an increase of nearly 700 million gallons over the 2016 level.
When Congress first embraced ethanol, legislators thought adding it to gasoline would stretch fuel supplies, be cheaper and better for the environment, and reduce our reliance on oil imports.
As is turns out, most of those assumptions are no longer true.
First, ethanol hurts drivers. Existing blends provide fewer miles per gallon, forcing drivers to pay more to travel. According to the Institute for Energy Research, the RFS has saddled American drivers with an extra $83 billion at the pump.
Second, increasing the percentage of ethanol in our gasoline past the current 10 percent “blend wall” could harm engines, especially in older cars. But Congress mandated that oil refineries increase annually the amount of ethanol they mix with gasoline. The problem is that gasoline usage has remained relatively flat since the recession, so the only way to meet the mandate is to increase the ethanol blend — putting engines at risk.
Third, ethanol production hurts the environment. About 40 percent of corn grown in the United States goes into our gas tanks. Farmers have plowed up massive tracts of grassland and wetlands to plant more corn, which is the key ingredient in ethanol. That conversion releases carbon stored in soil, plus the corn must be harvested, transported and refined before being added to gasoline. The non-profit Environmental Working Group has called the increased use of ethanol a “climate disaster.”
