A very dim future unless there is a breakthrough in battery technology.

Gasoline has approximately 50 times the energy density of the best battery today measured by weight. So this means to get the same amount of energy from state-of-the-art battery technology as 20 gallons of gasoline the weight works out like this:
Gasoline is about 6.4 lbs/gal, so 20 gallons is 128 lbs plus about 20 lbs for the tank totaling about 150 lbs.
Lithium-ion batteries with the same amount of energy as the gasoline will weigh about 750 lbs plus packaging.
The heavier vehicle will wear out tires and brakes faster, work suspensions harder, increased volume of the battery packs will decrease cargo capacity.

And at the end of it all, you still have to generate electricity to charge the batteries. How do you suppose that we will generate the electricity - oil, natural gas, coal, nuclear, wind, solar. Mostly it just moves the pollution from one source to another.
