Ethanol also gets huge government subsidies, around 50-70 cents per gallon? the person who told me that bio-diesel was not very energy intensive to produce was a farmer who has been growing oil crops for bio-diesel for a number of years now and they wanted to find out for sure how much energy it took them to produce their fuel so they kept records of all the fuel used to produce the fuel they used on the rest of their farm along with electricity used to run the press and all of their other inputs, I wish I could find my notes, but it was a tiny amount of energy was going in to their fuel.
