Ethanol is a big loser in cars and biodiesel is a likewise big loser for big agriculture. The problem is ER/EI of 2:1. Half your future crop is consumed in trying to make the other half into fuel to do it all over again. And tying up the land that used to grow food. Right now we are extracting oil at 20:1 and the world economy is barely hanging by the thread of a debt to GDP ratio of 4:1. If we have to start farming with fuel at 2:1 the food output will drop and the price will skyrocket. Or even sooner than the doomsday biodiesel scenario when we platue traditional oil and have to start relying on fracked oil and deep water oil at 8:1 or tar sands at 3:1.
