Don’t electric vehicles actually just move pollution to another location? 

Electric Vehicle (EV) Questions
No. Plug-in electric vehicles use power from the grid which comes from power generation plants. Power generation plants, even coal burning ones, are inherently more efficient and less polluting than vehicles due to efficiency of scale at which they convert fossil fuels to electricity. Also, an electric car is far more efficient than a gasoline car, so the amount of pollution generated by producing the electricity to drive an EV a given distance is much less than the pollution from the gasoline to drive an internal combustion car the same distance. Whereas an internal combustion engine car – even those powered by hydrogen, ethanol, and biodiesel – can make use of only about 20 percent of the energy that it consumes, a battery electric car is able to put more…

What’s the difference between an EV and a hybrid?

Electric Vehicle (EV) Questions
Electric vehicles (EVs) do not have an internal combustion engine. The batteries are recharged from the electric power grid, for example your home electric system. Hybrid vehicles have both an electric motor and an internal combustion engine. In most systems the internal combustion engine is used to recharge the batteries as well as power the car directly when necessary, but the only way you get energy into the car is to put gas into the gas tank. Therefore hybrids, while more efficient than standard cars, still use petroleum products and at the current time none on the market can use energy from the power grid or "plug in."

What’s a “plug-in hybrid”?

Electric Vehicle (EV) Questions
Plug-in hybrids are the same as a hybrid with the added ability to charge the battery from the electric power grid as well as from the internal combustion engine. However, there are currently no plug-in hybrids on the market. There are hobbyist conversion kits for some models of hybrids. Many manufacturers are working on plug-in hybrids, however, and we will see them on the market in the very near future.
