Ethanol is a joke. It takes more energy to create it than you get back. You need fertiliser, water pumps, tractors, trucks, distillers… The distillation process alone consumes massive amounts of natural gas. You might as well use the natural gas as fuel directly. Economically ethanol makes sense only because big agriculture bribes the government to give it huge subsidies. The other major problem is corn grown for ethanol displaces crops grown for food. For it to work, the raw materials must come from non-arable land.
