Study shows ethanol is worse for the environment

Young corn plants grow next to the Guardian Energy ethanol plant in Janesville, Minn. Five years ago, the U.S. government projected that in 2012, ethanol production would use up 30 percent of the nation's corn supply. Last year, it used 40 percent.

A new study on biofuel made from corn residue has shown it to be worse for the environment than gasoline in the short-term. It's not the first time research has cast doubt on the carbon efficiency of these types of fuels.

What's different is this one was funded by the federal government and it flies in the face of current White House policies. Here to tell us more is Dina Cappiello, an environmental reporter for the Associated Press.
