They closed their nuclear power stations which made them even more dependent on natural gas which was in short supply, leading to an increase in the use of coal (which is supposed to be "bad for the climate" due to the higher CO₂/TWh coefficient) and an increase in electricity import dependency which in turn drove up prices in the rest of Europe. German industry is both dependent on electricity as well as natural gas, the decision to close those - perfectly functional - nuclear power plants reduced the amount of natural gas available to industry even more since it was now also needed more for electricity production. I already mentioned the higher electricity prices.
In short the "traffic light coalition" chose ideology over logic as well as ideology over the will of the German people [1] to the detriment of all - even the ideologues even though they will be hit less hard since they have well-remunerated positions and state pensions.
