But forget hectares and efficiency, the worst thing about corn-based ethanol is that it’s not even clean. A recent [as of 2009] University of Minnesota study found that corn ethanol is actually worse for the environment than regular gas.
So corn ethanol is not only inefficient and expensive, but it also makes the problem we’re trying to solve even worse. Genius! I can see why Washington threw $3 billion at it in 2007, an amount that represented 76 percent of all renewable-energy tax credits."
