This is the tragedy of the commons because there is no clear winner.

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.

The assumptions made by some of the authors were not based on the best data, or were just a little bit too convenient, and had a strong impact on the results.

We found unequivocally that it does not take more energy than you get out of the amount of ethanol. So it's a net good if you grow ethanol and use it.

You're not going to save the world this way. People are doing it at their discretion.

Both state and federal support is critical to building a real ethanol industry. Real action is needed, and the $150 million per year President Bush promised is wholly insufficient.
