Excerpt from this news "Ozzie Zehner argues that battery electric vehicles (BEVs) are essentially trading one environmental problem for another rather than moving the ball forward on clean transportation. He makes a compelling case by arguing that the greenhouse gas (GHG) cost of electricity generation is too high, the production of BEVs is worse than gasoline vehicles, and that any personal automobile is ultimately worse for the environment than public transit."

Excerpt from this news" In fact, manufacturing an electric vehicle generates more carbon emissions than building a conventional car, mostly because of its battery, the Union of Concerned Scientists has found."
The best Green transportation in my Opinion is transition to pedestrian (walking) and bike-friendly vehicle.
