I think the current conflict between Russia and the US is pretty stupid and a remnant of the cold war that has been rekindled for some reason. 15 years ago Germany had a vastly better relation to Russia and the situation was far more stable and peaceful. Return of aggression were almost unthinkable. All this has been destroyed by diplomacy of the last decade. I don't really care if it was Putin that needed to deflect from domestic issues or NATO that dabbled to deeply in Ukraine that ultimately lead us in this situation. Fact is that the situation vastly deteriorated.
But all that should be disregarded for energy policy. To get off coal, gas is the vastly superior energy source. Still a fossil fuel, but far less dangerous. Nuclear power cannot be brought up fast enough and there are political problems too.
