I didn't forget a thing. The link below will show you how they count all the inputs for growing, transporting, and producing ethanol. The energy gain can be as high as 4 to 1 under some scenarios.

None of this would be economical if we were not already growing the crop to put protein in our food supply. But they still count the emission for growing the crop when they do the lifecycle analysis.

The energy gain comes from solar energy stored in the carbohydrates.
