Sure from a Ukrainian point of view NSII sucks. But it isn’t even close to an existential thing for Germany. The gas dependency is temporary (<15 years) and could also be filled by US LNG. Which is why the US is against NSII
So yeah from a geopolitical point of view this is all very interesting. From an ecological point of view the net impact is close to zero
Until they reach the lower limit with all the gas plants deployed, then they'll really have to think again about how they will definitely remove those plants.
Gas is really the best backup for renewable. It's cheap (for now), really adjustable (perfect for the renewable intermittence, on the contrary of nuclear), easy to deploy (not that easy with nuclear plants). The only issue is that it still emits a lot of CO²… and that you strongly depend on other countries for your energy (gas cannot be store as easily as uranium for example).
