A typical 100-kilowatt-hour Tesla lithium-ion battery is built in China on a largely coal-powered grid. Such an energy- and carbonintensive manufacturing process releases 13,500 kilograms of carbon dioxide emissions, roughly equivalent to the carbon pollution released by a conventional gasoline-powered car traveling 33,000 miles. That 33,000-miles figure assumes the Tesla is only recharged by 100 percent greentech-generated electricity. More realistically? The American grid is powered by 40 percent natural gas and 19 percent coal. This more traditional electricity-generation profile extends
