Sure, until Musk's prediction of half of all cars sold being plug-in EVs by 2020 comes true. At that point, it will be pretty annoying when I lose power every night because half of the houses in my neighborhood are charging their cars.

And I definitely look forward to breathing the additional coal plant emissions that will be necessary to overcome resistive loss in the grid. (Of course, refining gasoline requires a fair bit of electricity on its own, but refineries are centralized sites with industrial power service, like charging sites for leased EV batteries would be in an ideal world.)

The idea that plug-in EVs are somehow a magical workaround for the externalities of gasoline-powered vehicles is troublesome. A sustainable future for EVs means addressing the externalities first, because they won't go away on their own.
