Selling Teslas in China Won’t Do Much for the Environment
MIT Technology Review

Sales of electric vehicles in China, the world’s largest auto market, have been minuscule despite government incentives meant to put five million of the cars on the nation’s roads by 2020. Tesla Motors hopes to begin changing that as it makes its first deliveries of Model S sedans to customers in China this month.

But while having more EVs might help China reach its transportation goals, it probably won’t improve the environment, given the country’s reliance on coal for more than 70 percent of its electricity. Making matters worse, coal in China is often dirtier than it is elsewhere, and many power plants don’t employ modern emission-control technologies.

Recent research led by Christopher Cherry, a professor of civil and environmental engineering at the University of Tennessee, has shown that in much of the country, an electric vehicle the size of a Nissan Leaf accounts for roughly the same amount of carbon dioxide per mile driven as a comparable gasoline-powered car. On top of that, EVs in China account for a larger amount of dangerous particulate emissions than conventional cars.

N’en déplaise aux verdoyants, le véhicule électrique, en plus de ne pas être très pratique, ne sauvera pas la planète… Mais cela ne devrait pas empêcher les gouvernements de gaspiller des milliards dans des programmes de subventions, histoire de faire plaisir au lobby vert…
