Electric cars and wind turbines run on copper, and the DW team follows the metal from smelter to open pit to show what that demand costs. Hamburg's Aurubis, Europe's largest copper producer, posted more than 530 million euros in pre-tax earnings in 2022 while processing over 1.2 million tons of copper drawn largely from Chile. The film travels to Chuquicamata in the Atacama Desert, home to the world's largest open pit copper mine, where interviews with residents describe water shortages, heavy-metal contamination, and a cancer rate reported to be up to six times the national average. Company representatives point to codes of conduct and supply-chain standards, while local communities describe a different reality on the ground. The film also turns to Germany's Lusatia region, where an estimated 130 million tons of copper sit underground, and asks whether reopening domestic mines could ever be done without repeating the Atacama's damage. The result is a grounded look at the raw-material bottleneck sitting underneath the green energy transition.
