 Anglo American Plc said on Wednesday it would use only renewable sources to power its mine operations in Chile beginning in 2021, thanks to a deal the global miner signed with the Chilean subsidiary of Italian energy giant Enel . Renewable energy supplied by Enel Chile will power Anglo Americans flagship Los Bronces copper mine, as well as its El Soldado and Chagres operations, the company said in a statement. Global miners are increasingly seeking innovations to boost efficiencies, lower costs and reduce use of water and non-renewable energy at mines.
