I think a lot of peolple get the ethanol and bio mixed up. The thing with ethanol is that the extraction process is extremely complicated. If you look at a ethanol plant diagram and then compare it to a soy plant your reaction would be "whoaa."

I'm not harping on biofuels, we have been using soy diesel since the 80's. However, the amount of coal being burned for power (for ethanol plants mostly) has gone up drastically in the midwest.

New York Times.... blah... lol
