Read here and here. Scientists from both China and America (Argonne Labs) conduct study that finds a wide adoption of electric vehicles by Chinese populace would dramatically increase greenhouse emissions. As with many of the climate alarmist solutions, the cure is worse than the disease.
"We have here another study that points to the fact that widespread adoption of electric vehicles (EV) could actually increase greenhouse-gas emissions rather than reduce them as we had hoped. This study, conducted by the Argonne National Laboratory and China's Tsinghua University, specifically focuses on China and concludes that mass EV adoption could lead to tremendously higher emissions of carbon dioxide, nitrogen oxide and sulfur dioxide due to the country's widespread use of coal as a power source."
