Ethanol is Not the Answer

At least ethanol is not the answer to our energy problems. It may indeed be the answer to the question, “What biofuel is used by politicians as a political ploy to satisfy environmentalists while they escape making politically difficult decisions?”
Ethanol actually makes gasoline costlier and dirtier. But, conveniently, the benefits of ethanol subsidies flow to politically-connected corporations and farmers, thus making it a potent source of votes even if its usefulness as a source of fuel is suspect.
