$Tesla (TSLA.US)$ $Ford Motor (F.US)$ $General Motors (GM.US)$ The U.S. has enough reserves of lithium, copper and other metals to build millions of electric cars, but rising opposition to new mining could force the country to rely on imports for the metal and slow the country's progress in electric vehicles. The move to import metal for electric vehicles in the U.S. could increase greenhouse gas emissions by increasing transportation from overseas mines to processing facilities in the U.S., somewhat undermining efforts to reduce emissions by building and using electric vehicles.
