This is actually one of the cheapest possible transitions you can make. It cuts the cost of fuel by half at the pump.

This is actually a switch we could make very easily and very quickly.

It looks to be that you can get just about twice the amount of energy by going the cellulose route, and greenhouse emissions are very small.

Corn is an OK source for ethanol. But if you really want to hit a homerun, you need to go to cellulose.

The people who are saying ethanol is bad are just plain wrong.

Brazil is a big success story in this.

Converting to fuel ethanol will not require a big change in the economy. We are already ethanol ready. If ethanol were available on the supply side, the demand is there.

It is better to use various inputs to grow corn and make ethanol and use that in your cars than it is to use the gasoline and fossil fuels directly.
