Rising commitment from major automakers, rapid battery cost declines, strong policy support from state and local governments, and low operational costs have put electric vehicles on track to pass gasoline-powered vehicles. EV sales in U.S. have grown to an average of 32% annually from 2012-2016 and 45% over the year ending June 2017.

What penetration will they achieve, by when? How will these outcomes be affected by external factors like oil prices and government policy support?
