Green Energy

I think that is a bit of a mis-direct. We don't need that now, but we do need to develop it. There are plenty of electricity sources that provide enough for industry (plenty of hydro as a simple example).

The chemical processes require research and subsequent change, but removing thermal coal and just using coking coal is a massive reduction in coal usage. Maybe that is ok to get us over the hump. There is a lot of research into direct reduced iron, which is an example of removing coal from that particular process. It is not impossible, but currently maybe not too easy.
