I'm pretty sure it will be hydrogen fuel cell vehicles. I always hear that the cost of the infrastructure requirements would be too great. I never see numbers assigned for that cost. I also never see any numbers for the costs associated with updating the electric grid to handle increased power requirements from large quantities of plug in vehicles. What I do know is fuel cell vehicles have virtually no "carbon footprint" and hydrogen is a completely renewable energy. Those two facts alone make me think that is the direction the government will eventually push, whether it is a good idea or not.
