Electric vehicles just displace the pollution to the energy production site - the power plant. And batteries are expensive, heavy (therefore adding to the energy use of the vehicle), and they produce significant heavy metal pollution in production and disposal. Relying on an expensive solution will only delay the switch away from gasoline.

What are needed are renewable liquid fuels - bio-diesel, ethanol/methanol - that can be produced from plants so that there is no net CO2 emission. The problem is that the energy content of such fuels is about half that of gasoline (http://www.uvi.edu/Physics/SCI3xxWeb/Energy/GasolineFAQ.html), so you will get less mileage per gallon. But that is a small price to pay, and will be counterbalanced by the lower cost per gallon relative to gasoline.
