Where does copper wire come from? In the past, when it fueled the first electricity revolution that brought power into all our homes, it was mined in places like Butte, Montana and Bingham Canyon, Utah, pictured here. Bingham Canyon, better known as the Kennecott Copper Mine southwest of Salt Lake City, is the largest man-made excavation in the world.  Copper now figures squarely in the second energy revolution, this one involving the wiring in electric cars being advanced as replacements for gas-burning vehicles.
