Using our food supply for a poor fuel is a politically motivated "feel good" sham.<br><b>References : </b><br> It’s a dumb idea producing only a little half of the energy in the same quantity of gasoline.

And there are additional problems that will make ethanol-from-corn a losing proposition; the worst of those is the fact the it takes a food product that a) feeds us, and b) is sold world-wide, which helps slightly to balance our horrible foreign-trade deficit, and turns it into fuel to feed the maws of gas-guzzling SUV's. It is a near-certainty that ethanol from corn will be a disaster in the long run. That said, the fault is not ethanol's. If we could make ethanol from cellulose or garbage or any organic waste we could solve multiple problems at the same time. This will eventually happen, but probably not soon enough.<br><b>References : </b><br> It’s better than break-even, but not by much.

Corn has another down side. It takes much more fertilizer than other crops and much of the fertilizer that is applied to corn crops ends up in the runoff from the fields. In the US the majority of that works its way to the Gulf of Mexico where is causes a dead zone every summer. The only benefit is to Archer Danies Midland and the corn farmers.<br><b>References : </b><br> Jeff is correct, if ethanol is to be a true supplement to reduce oil consumption, it needs to come from places that are not as energy intensive as corn production.
