How much coal is going to be burned to replace clean natural gas?
Many coal mines in the Ruhr area and Limburg were water flooded back in the 50’s when they were contemplating the creation of the BENELUX. Instead of burning hi-BTU coal, they may have to burn low-BTU peat. Imagine the smoke hanging over the EU. Greta Thunberg will have her big O.
In Germany they are not only burning coal already, they are laying in supplies of firewood for the winter.
