Biofuels based on ethanol production are a total waste. Ethanol is a poor motor fuel at best and the energy needed to produce a gallon of ethanol is greater than the energy burning ethanol as a fuel. Corn ethanol is nothing a but a bloated farm subsidy program. We could quickly end the ethanol.prgram if Congress would pass legislation mandating that farm machinery must use biofuels.
Even when you consider the amount of energy needed to produce fertilizers, operate farm equipment, transport corn, convert corn to ethanol, and distribute the final product - the energy contained in a gallon of corn ethanol is 50% more than the amount of energy needed to produce and distribute it.
The more ethanol is used on input activities, the better the ratio becomes. Ethanol isn’t going away.
