Ok. I sell electric vehicles for what we'll laughingly call a living. I actually *like* some of them (the Zero S Motorcycle and the Wheego LiFe come to mind). They aren't the answer for every need and locale, but for quite a few, they are just dandy. When gas is getting up near $4.00/ga or better...electric looks better and better.
Biofuels, however, are an obviously bad choice. There's only so much arable land in a given region, and that land can either be dedicated to growing bio-fuel or growing food...and for every acre growing biofuel, that's an acre not growing food - and thus driving the price of food skyward...not a good thing.
Read the article - it has more data than I have energy to present :)
