A major question in the production and use of fuel-grade ethanol is whether or not it yields a net energy gain after accounting for the fossil energy input required for bio-mass production, harvesting, transportation, and conversion. Two recent studies concluded that a net energy loss resulted in industrial-grade ethanol production from corn. Use of fossil fuel was assumed for all energy inputs.
