What will fuel the cars of the future? Will the cars of 2025 run on electricity, hydrogen combustion engines, ethanol or bio-diesel, solar power, or some hybrid combination of any number of these? Ethanol was touted by the U.S. government very briefly for reasons that seem in retrospect to be more political than practical. Ethanol has lower emissions than gasoline and can be produced right here in the United States, but recently studies suggest that it actually takes more energy to produce than is contained in the fuel itself, making the environmental impact kind of self-defeating.

Ethanol costs about $2 per gallon, which is less than Petroleum based fuel, but cars using E85 (an 85% Ethanol blend) get 10-20% few miles per gallon that run on regular gas. On the up side, some cars specially made to run on Ethanol based fuels (like the Chrysler Sebring, Ford F150, and GMC Yukon) are already on the market and are no more expensive than regular models.
