The standoff between Big Oil and Big Corn

A decade ago, lawmakers in Washington tried to address a trifecta of thorny challenges with one simple fix that has turned out to be anything but easy to assess.

The solution: the Renewable Fuel Standard, commonly known as the ethanol mandate. Enacted in 2005 and expanded two years later, the legislation required that refiners blend an increasing amount of biofuel into the gasoline that powers most American cars. Indeed, depending on whom you ask, the Renewable Fuel Standard is either one of the best policy decisions to come out of Washington in decades or a special-interest boondoggle that costs taxpayers billions of dollars and harms the environment.
