Electric Arc Furnaces are probably our best bet for that - they’re an established, proven technology and can be swapped over to a green power source without any other changes (assuming the society has the energy capacity). I think I remember reading that a factory somewhere in Europe had already done that but a quick search has failed me.
Certainly, they’re the shit, but the energy capacity you mentioned is a huge issue. As I said in my other comment it should/could/has to be done, but it’s anything but simple.
