You are using the word "ideology". That isn't the hallmark of good arguments. But may be we can agree onto that the current government is trying to fix all the problems caused by the previous one.
The problem wasn't shutting down the mostly old nuclear reactors, the problem was curbing the ramp up of renewables. But fortunately, the current government is fixing that. Which brings energy prices down and while currently we are hit by many factors, quickly can become a big support for Germanys economy. It might be expensive leading a trend, but it does pay of long term.
