Report: Electric car has twice the global waring potential...

TheBlaze has reported on the not so green side of electric cars before — those being charged with electricity from coal-fired power plants contribute more pollution than their gasoline-fueled counterparts. Now, a report of the Norwegian University of Science and Technology takes a look at the manufacturing of electric vehicles and found that’s not so great for the environment either.
“Although EVs are an important technological breakthrough with substantial potential environmental benefits, these cannot be harnessed everywhere and in every condition,” the study authors write. “Our results clearly indicate that it is counterproductive to promote EVs in areas where electricity is primarily produced from lignite, coal, or even heavy oil combustion.”
Published in the Journal of Industrial Ecology, the researchers found the production of electric vehicles is “more environmentally intensive” than those with an internal combustion engine. Producing the electric powertrains and traction batteries are among the factors that “add significantly to the environmental impacts” of production.
The study also took a look at the environmental impact of electric vehicles compared to traditional cars when it comes to actually taking them on the road. Like the study we reported on earlier this year, EVs with electricity supplied by coal were found to have more of a “global warming potential” — increasing it by a factor of 17 to 27 percent — compared to traditional cars. EVs using electricity supplied by the “average” European source reduced global warming potential by 20 to 24 percent though.
