CERAWeek: Electric cars, trading emissions with utilities?

OK, that electric car won’t spit emissions from the exhaust pipe, and a hybrid spits less. But when they’re plugged in to recharge, don’t they just add that many more emissions from the power plant providing the electricity, effectively switching the emissions from the tailpipe to the smokestack?
A little, says Andrew Tang, senior director of Pacific Gas & Electric’s Smart Energy Web.
Yes, if the transportation sector is “electrified,” emissions from power plants will increase as more electricity is used.
But overall, Tang said net emissions would fall as electric motors replaced those powered by gasoline.
