In a blow to electric vehicles (EVs) being the solution to global warming a new study shows that EVs might pollute more. The study, by the Norwegian University of Science and Technology found that green house gases were increased if an EV is charged from electricity produced by burning coal. The study also went on to look at the entire life cycle impact of an electric vehicle. The production of an EV has significantly larger environmental footprint then a conventional vehicle.
"The production phase of electric vehicles proved substantially more environmentally intensive," the report said, comparing it to how petrol and diesel cars are made.
"The global warming potential from electric vehicle production is about twice that of conventional vehicles."
"It is counterproductive to promote electric vehicles in regions where electricity is primarily produced from lignite, coal or even heavy oil combustion."
"A more significant reduction in global warming could potentially be achieved by increasing fuel efficiency or shifting from petrol to diesel," the report said.

With 44% of the US electricity coming from petroleum or coal does an EV in the US make sense if the goal is a reduction of green house gases?
