The production and manufacture of corn-based fuel in this scenario uses more energy than the resultant ethanol contains. You can look it up.
But it seems a lot of the discussion becomes speculative. E.g. I have read and been told not to use ethanol fuels in my 135i as it is a bad thing. It also seems to be that ethanol dissolves water, dilutes the fuel and promotes corrosion of metal parts.
I've read that Esso 91 here in Canada is ethanol free, but I'm not sure, so I usually fill up with expensive Shell. (Almost $7.00 Canadian per Canadian gallon of 4.55 L)

While so far 10% Ethanol hasn't affected any of my vehicles or lawn mower equipment, I can tell you with 100% certainty Ethanol F'd up the fuel tank on my 2009 Ducati 848. All Ducati bikes of that generation using tanks sourced from Acerbis were affected. The mildest damage would be your tank would develop bubbling or bowing on the surface of the tank. At its worst, the tank would stretch so you couldn't reattach the tank or in one case the ventilation tubes inside of the tank snapped and allowed fuel to pour out of onto the engine.
