I see that GM E85 commercial all the time. And Bush was touting it during his State of the Union speech. But I'd like to hear more about biodiesel. Like I've said before, biodiesel is a lot more energy efficient than ethanol. Frankly, we need both so it doesn't make much sense to focus all of our attention on ethanol, but I wouldn't be surprised if biodiesel eventually becomes the more prevalant alternative fuel, though that will take time considering 99% of the passenger vehicles in the US are powered by gasoline and US gasoline consumption is about twice as high as that of diesel.
