Making ethanol from corn is a good thing if you want to offset fossil fuels from overseas. On the greenhouse gas side of things, it is not clear if corn, as grown today, is a good thing. We just don't know yet, but it appears to be a mildly good thing.
Corn is an OK source for ethanol. But if you really want to hit a homerun, you need to go to cellulose.
