When ethanol burns it doesn't produce any green house gases, cool. But part of ethanol production is fermenting sugar into alcohol, a byproduct of which is carbon dioxide. I don't get it.

There's only so much corn to go around. If you do the sums the amount of gasoline that can be replaced by ethanol from the wheat grown in the US is about 5%. Check this out

Ethanol does release CO2 when its burned, but growing the corn pulls CO2 out of the atmosphere, so they're less of a net increase. Ethanol as a fuel replacement is still retarded however.

True, corn plants pull CO2 from the atmosphere, but the question is: does corn pull more CO2 from the atmosphere than the forest lands that were cleared to grow corn? Somehow I doubt it. That would make a net increase of CO2, no?
