As this eventful year nears its end, let it be remembered for the rise of the electric car.
Sales of plug-in electric cars -- both hybrids and battery electrics -- tripled in model year 2012, their second year on the market.
Plug-in hybrid sales have surpassed the sales of conventional hybrids in 2001, which was their second year on the market.
Despite the political rhetoric of the election year, the most popular electric-drive vehicle, the Chevy Volt plug-in hybrid, is outselling half of all cars on the market today. In the meantime, conventional hybrid sales grew by more than 50 percent in model year 2012, more than four times as fast as the rest of the vehicle market.
