Supporters of ethanol fuel claim that its widespread use has reduced gasoline prices in the U.S. But according to a study at the prestigious Massachusetts Institute of Technology, ethanol production has almost no impact on gas prices, and claims to the contrary omit important variables and rely on seriously flawed statistical data. Right now, 10% of all U.S. gasoline comes from corn ethanol – up from just 3% in 2003. With Congress considering upping the renewable fuel standard for ethanol to 36 billion gallons within a decade, you can be sure the debate over the merits of corn ethanol won’t be unhusked anytime soon.
