Industries have moved east and west from Germany because energy is just too expensive (besides too expensive labour due to high state quota as well). In Brandenburg, Chemical plants are threating to shut down because gas prices are out of whack (50% of gas price is tax). This is an extremely high cost for a national economy to pay.
Major consumer energy seller E.on has stopped selling household gas delivery contracts. Transportation cost in gas, diesel and electric car terms is skyrocketing as well. This makes all goods that are getting shipped more expensive. Germans are the poorest people of Western Europe. After tax, salaries are quite low. €500 to a €1000 more in yearly energy cost is a significant burden on many households, dampening spending in any other area including long retirement saving/investing.
All of the above will deconstruct industries, ruin household finances of the already pressured middle and lower class, and set the expectations for years to come when it comes to regulatory politics --- which during the past 20 years were the equivalent of shitposting on 4chan, just dressed up in nice suits and sitting in ideologically blind party councils.
10 all new power plants are chump change compared to that.
