Rio Tinto is moving to solar (and some wind) here in Australia for its aluminum refining and smelting operations. Would be good if the same could be done for steel too.
Aluminium has traditionally been smelted with electricity. It's easy to move to green tech
Steel is harder. There is serious work that had been going on for years trying to come up with new low emissions ways of making steel
