In all fairness, it's not as if this regressive step of turning back to the use of coal is something they want to do. Many of them have long been on the road to reduce, if not totally eradicate, the use of coal. But it seems they're left with no choice, at least for now.
To me, however, this is the right thing to do, the lesser evil, because the other option is to tolerate Putin's madness and desire to wreak violence and death on an independent nation and a peaceful people.
I believe this regression is merely an emergency step.
