Electric vehicles are hitting the streets in larger numbers, led by models like the Nissan Leaf and Chevrolet Volt. By one estimate, there could be more than 600,000 EVs on U.S. roads by 2014, but that's a speck in the rear-view mirror compared to the roughly 140 million passenger cars Americans already drive.

This week, energyNOW! explores the state of electric vehicles in America today: are they accelerating into the fast lane, or could they run out of juice in the race against internal-combustion cars?
