We are trying to get more heat pumps installed, but people are still proud of getting a new gas furnace installed in 2023, thus avoiding a potential ban and betting on guaranteed dirt-cheap natural gas for another 20 years.

But either way, nuclear power is history in Germany and it makes absolutely no sense to bring it back. We never had a lot of nuclear power to begin with and the few power plants that could maybe be reactivated with a ton of money and labor are just a drop in the bucket. Building new reactors takes decades from initial planning to going live and nuclear construction projects are notorious for immense cost overruns. Plus, there are only a few construction companies in the world that have the capabilities to build a nuclear reactor and they're already tied up in other projects. We would need dozens of new reactors built simultaneously and they would still be finished too late to contribute anything meaningful to a carbon-free electrical grid.

At the same time, wind energy is a dirt cheap, proven technology that is much more easily deployed, scales really well, is decentralized and reliable. Yes, it can be intermittent but it's predictable (weather forecasts exist). And if we had invested a fraction of the R&D budget for nuclear fission and fusion into energy storage technology, it would be a complete non-issue. We have some work to do in that regard, but sodium ion batteries are pretty far in development and should be much cheaper. Iron redox flow and liquid metal batteries also have potential, maybe hydrogen. Demand response will also be a big factor. With flexible pricing during the day, both households and businesses can save a lot of money by using more energy whenever there's a lot of it and less when it's scarce.

Yes, it could and increasingly is. But that still doesn't make it true that the nuclear power was replaced by gas.

That is just misinformation. First of all, nuclear power never contributed that much anyway. If all nuclear power plants ever built in Germany were running at full load 24/7 for 365 days of the year, they would produce 231 TWh, which is less than 10% of our total energy demand. So there was never that big of a hole to fill in the first place. Especially in the last ten years, when only a handful of power plants were still in service.

In reality, renewables have managed to replace both nuclear power and a large chunk of fossil fuels (source). Last year we had to export enormous amounts of energy to France, because their nuclear plants had proven so unreliable (source). This has admittedly led to an increased use of fossil fuels, which we could have avoided by building more renewables here (or in France).

I just called out this particular piece of misinformation. Being of the opinion that Germany shut down nuclear power plant prematurely doesn't make it okay to spread misinformation, does it?

And if you tell that lie annother million times it will become true.

Really! you just need to nelieve real hard in ti and then reality will adapt and the propaganda hammered into your head will finally become true.

If you're asking where stuff /could/ come from, why couldn't we just build renewables. For Germany at least, the ship has sailed anyways. It is not currently legislatively and practically possible to build out the required energy infrastructure with nuclear to phase out gas in a timeframe that makes sense. With the beaureaucracy and everything, it'll be at least a decade before even the first power plant would be connected to the grid.
