> In hindsight, it was premature by Germany to shut down theirs so early
This is a widespread talking point that is more wrong than correct:
Germany did not shut down its nuclear reactors early. In fact, those reactors should have been shut down decades ago. They had been well past their intended shelf lives.
The decision to finally shut them down also dates back to Merkel during the Fukushima incident (2011). So the timeline to shutting them down wasn't exactly short either. The last nuclear reactors were shut down well more than ten years after the original decision was made.
What you can blame Germany for is not building new nuclear reactors. Germany hadn't built new nuclear reactors since Chernobyl - the last reactor to come online was in 1988. The influence of the anti-nuclear protests was strong enough to prevent the construction of new reactors but not enough to phase out the ones that existed. Instead Germany continued extending their runtimes over and over again because this was easier to justify politically (or rather because it was less obvious than building new ones).
So in other words: it took Germany from 1986 (Chernobyl) to 2023 to shut down its reactors. But it did so in an extremely irresponsible way. And it still didn't have proper plans in place like investing in grid infrastructure and storage necessary to expand renewables.
That said, nuclear power is overrated as the one thing it does well is constant stable energy production. But the problem in the modern grid is not not having enough energy, the problem is not having enough energy on demand. Renewables can provide enough energy but they are unstable. You need something to cover those dips and nuclear doesn't work for that because you can't really scale it up and down much. Storage would be ideal but for the majority of time since the reunion Germany has been under a conservative government which doesn't want to spend money on infrastructure maintenance let alone investments (let's see if this conservative government will do things differently as Black Rock Merz has been promising in between his anti-woke populism). But for the time being the only option Germany has is fossil.
