A gas station in San Diego has started selling a wide variety of fuels, including E85 (85% ethanol/15% gasoline) and BioDiesel. Once you get over the heart-stopping price of high-grade gas ($3.73, read it and weep), a couple interesting things come out of the sign: bio-diesel is only $.10 a gallon more expensive than dino diesel, and E85 is a whopping $.74/gallon cheaper than high-grade gasoline (a fair comparision, since E85 is about 100-105 octane).
Of course, at present, the only cars that can use E85 are cars that come dual-fuel from the factory, or pre-'74 cars that have been modified to run on ethanol. But it's a start.
