Electric Vehicles Are Not Greener Than Comparable Gas Powered Autos

Posted by Milton Recht:

From National Review Online, Planet Gore "Tesla and the Myth of the Zero-Emissions Vehicle" by Henry Payne:
According to a comprehensive engineering study published in the February 2013 Journal of Industrial Ecology, greenhouse gas emissions for an EV’s full life cycle — from production through road use — are not much greener than a comparable gas-powered auto, and no more planet-friendly than a diesel car. Indeed, when you factor in the toxicity of materials used in battery production, it’s hard to make the case that EVs are a very green alternative.

"Almost half of an EV’s life cycle global-warming potential is associated with its production," concluded a study group from the Department of Energy and Process Engineering at the Norwegian University of Science and Technology. "We estimate the GWP [global-warming potential] from EV production (to be) roughly twice (that) with gas-engine production."
