New York City was particularly green on the night of February 11th. Well, the nightlife was at least. Not only did Nissan hold a promotional event for their soon-to-be-released Leaf electric vehicle, but the New York Academy of Sciences hosted an expert panel to discuss NYC’s infrastructure readiness for the flurry of EV’s on the way. In case you didn’t know, the Leaf will be the first affordable (i.e. not a Tesla), mass market EV to hit the streets when it rolls into dealerships this December. Yes, I know…Chevy’s Volt is due out first in November. But the Volt is technically not a pure EV – it’s a range extended EV. That means an internal combustion engine, or ICE for short, adds longevity to the electric motor when the battery is kaput. Only time, and consumer demand, will tell how drastically these alt energy vehicles will affect energy consumption in major cities. But there is certainly no shortage of buzz on the matter. More pics from the snazzy Nissan Leaf event after the jump.
