You still avoid local pollution, noise and overall CO2 emissions are all lower pretty much anywhere in the world. In addition to this, a larger amount of electric cars that can work as storage can help greatly to increase the share of renewables (e.g. by offering lower prices at times of overcapacity). It's a hen-egg problem. You need large storage capacity to enable renewables. But without renewables, storage isn't utilized and therefore not profitable.
