There's a lot of metallurgical coal necessary for the construction of certain high-grade steels, such as those you'd find in wind turbines.
Similarly, try and make a PV solar cell without coal in the value chain. You can't (I can).
Arguably, some coal jobs are green jobs.
The thermal coal industry, long on the ropes, and not at all green, has not been recovering.

It's basically irrelevant to coal as a pollution or economic issue. Any resource that uses coal can be replaced by a renewable source. Coal is just a carbon source, and carbon is one of the most accessible elements. Producing very pure carbon from biomaterials produces energy and is very similar to the production of coke from coal. It's very economical and the only reason it isn't used is because coal is so insanely cheap.
