U.S. plug-in cars come closer to reaching 1 million

U.S. plug-in cars come closer to reaching 1 million: For the first time modern plug-in electric cars became available in U.S. in December 2010, the times when Nissan Leaf and Chevrolet Volt's first generation became available on the car market. After a short time president Barack Obama set the goal of putting 1 million plug-in cars on U.S. roads by 2015. This goal wasn't reached.

In fact, U.S. electric-car sales have only just gotten halfway there. Combined U.S. sales of battery-electric cars and plug-in hybrids surpassed 500,000 units as of September, according to the U.S. Department of Energy. Specifically, sales since December 2010 reached 512,137 units in September.
