Ethanol is a little lower in energy per volume, but that only translates to a couple of MPG less in modern car engines. And, less harmful emissions. And the carbon dioxide released by burning ethanol is at least partially reclaimed by growing the plants (corn, sugar cane, etc.) to make the fuel. Ethanol used to be significantly more expensive than fossil fuels to produce; hence, generous subsidies. That has changed significantly. Ethanol is domestic, and helps tame the market volitivity of foreign oil supply. However, in the U.S., that's of little concern anymore because of domestic shale reserves and production.

The biggest problem I have with Ethanol is an ethical one. I don't think we should be using food crops for fuel when hunger is still the daily reality for millions of children in the world.
