Well, it seems biofuel is a dead end road, too. We can't use all our land to produce fuel for cars, instead of producing food. So it would lead to increased deforestation - as it happens already in some countries. That is certainly not desireable.
A better system could be fuel cells driven by hydrogen. Which is basically also a electric system. Hydrogen is produced with electricity and then turned into electricity again in the car. That doesn't require batteries and its fast to refill the tank.
But hydrogen can be pretty dodgy stuff, if something goes wrong.
