The revolution is upon us. 2010 is the first year all the bill auto makers are rolling out fully electric cars: GM, Honda, Mitsubshi, Kia, Toyita and Chysler (not sure about Ford). I think it will take off slowly like the hyprids, but it will speed up. I think we will see a transformation over the next decade from gas/oil fueled cars to all electric cars. From 2020-2030 I wouldn't be surprised if gas fueled cars get entirely phased out.
