It is necessary to find cost-effective ways to replace coal with renewables or to be able to use coal and lignite in a climate-friendly way (clean coal technologies, methanol economy, carbon capture, storage, and recycling) to make decarbonization not only an alternative for rich countries, but a truly global option.
There is no transition. This is “all of the above” i.e. build more of everything, green or dirty, the only goal is growth.
