Since the energy required to produce corn ethanol is nearly equal or sometimes greater than the energy gained as fuel, corn sucks. It should be obvious that you are going to produce more emissions with corn. Even when the tarsands require large amounts of refining, that tarsand oil will be used to produce corn ethanol. Oil is used today in corn agriculture and production of ethanol. Corn as a biofuel is an odd stop-gap. If we have to use subsidies, why not encourage farmers to make some other crop that transforms to oil with higher efficiency?
