Biofuels have the potential to put rich people's driving (by the standard of anyone with a car is rich, but especially in areas like the US with our SUVs) in competition with both poor peoples' food and other environmental concerns.

There may be some biofuels that are not so bad, like ethanol from switchgrass. However, we must be very careful about how we implement use of biofuels. I'd personally stay away from them.

Electric cars running on the power generated by wind, solar, tidal, and other truly renewable sources will be much better than all biofuel options.

If the congress would pass HB 1009 and decriminalize agricultural hemp, there would be another source for biofuel and possibly ethanol. It's nuts to keep this 1937 law on the books.
Agricultural hemp is a source for food, fiber and fuel. It is also pest resistant. Cotton uses about 50% of the pesticides used in this country.

Good point Don. And while they're at it, perhaps they could throw a little more reason into the law and decriminalize medical marijuana too.
