As I understand it, running high temperature furnaces needed to smelt metals (new or replacement) currently requires fossil fuels (usually coal). That isn't going to be an easy problem to solve. Maybe use electric furnaces to lower the delta between air temperature and the desired temperature, and then use fossil fuels to bridge the gap?
