Artificial intelligence, electric vehicles, and clean energy may seem like industries of the future, but they all run on one of the oldest metals: copper.

Data centers powering AI need copper wiring and transformers. Electric vehicles use nearly four times more copper than gas-powered cars. Wind turbines, solar farms, and the modern electric grid all depend on it. As such, copper is a building block of tomorrow’s economy and the backbone of America’s national security.
