Another setback for liberal policy makers and environmental activists who promise enormous reductions in emissions as a result of converting America’s automotive fleet from gas-powered to electric vehicles as soon as possible. A new study by the Boston Consulting Group (BCG) says it won’t happen before 2020, even if, as many advocates propose, the government mandates it.

The reason is the same as it has been for decades – limitations of battery storage capacity mean electrics simply cannot go far enough soon enough at a competitive cost to enable them to offer desirable transportation products at prices that make them affordable and the kinds of functionality that make them desireable to consumers.
