"In terms of renewable fuels, ethanol is the worst solution," Patzek says. "It has the highest energy cost with the least benefit."
Ethanol is produced by fermenting renewable crops like corn or sugarcane. It may sound green, Patzek says, but that's because many scientists are not looking at the whole picture. According to his research, more fossil energy is used to produce ethanol than the energy contained within it.

Please. He's a liberal, oil industry shill who's research and data used to reach his conclusions used decades old assumptions about farming that are no longer true.
