"The only problem is that electric cars won't do anything directly to mitigate global warming, because they will still be powered largely by fossil fuel."

But electrical generation is more efficient than an internal combustion engine in terms of carbon output. According to PG&E:

"Additionally, from well to wheel, electric vehicles emit approximately 66 percent less carbon dioxide (CO2) compared with internal combustion vehicles. CO2 is the principal gas associated with global warming."
