It is good to remember that overall efficiency of an EV from power plant to road is lower than comparable gasoline hybrids. The e-mpg posted on the window sticker is more than a little misleading.
While the promise of a solar powered electric car is somewhat of a reality for certain owners, real world electrical generation losses (power plant to grid to charger to battery, then at a later time from battery to motor to wheel) mean that the EV is not the answer to national energy savings. Nor do they cost less per mile with regard to energy costs vs. modern gas hybrids.
Hybrids like the Prius, Camry, Accord, Fusion and others all have "power-plants" with 40% or 41% efficiency along with the EV's regenerative braking/energy recovery advantages.
It is my belief that automotive propulsion system that consumes the least energy is the gasoline (or possibly diesel) hybrid.

"Energy efficient. EVs convert about 59%-62% of the electrical energy from the grid to power at the wheels."

"if the [electric power plant] heat rate is 10,500 Btu, the efficiency is 33%" (which is the average of coal plants) Of course other fuel burning power plant eff's vary by type, with a national fuel burning elec power plant average around 38-40%.
