You don’t need ethanol—it is a poor substitute—more like hamburger helper..ethanol is a subsidy that is given for corn producers, not a form of energy.
I know it is hamberger helper, but the intention of the ethanol mandate is to extend the life of fossil fuel. This can be done with coal and natural gas. We have enough natural gas to use as a fuel but we would need a new transportation infrastructure. But if we convert it to ethanol little infrastructure needs to be built. It is thirty percent cheaper to make ethanol this way. Corn can be used for food.
