Buy a 'Green Car,' Grow Jobs: Energy-Efficient Cars Boost Manufacturing Jobs In 15 States

Though the number of Americans working on vehicle assembly lines and parts plants has shrunk considerably in recent years, a new report suggests that their number could grow significantly along with consumers' increased interest in greener cars and trucks.

Fifteen states in particular could benefit from the expected boom, including Rust Belt states where auto manufacturing has waned in recent years, according to the report, produced jointly by the National Wildlife Federation, the Natural Resources Defense Council and the UAW, the union that represents autoworkers.
