how is the chart ranging until 2022 relevant for 2023?

Germany needs to do a lot more to go fully renewable, like all countries need to do. And the conservative government under Merkel has been desastrous for the expansion of renewables.

But claiming that the remaining nuclear power that was shut off now as sheduled would have been replaced by coal is a lie.

Also Merkel didnt decide to exit nuclear in 2022. The decision was made in 2002 with the plan to ramp up renewables.Then Merkel throttled renewables and exited the exit from nuclear power only to exit the exit from the exit two years later. As a result 6 Billion Euros in "compensation" was thrown at the nuclear industry and renewables were not put back on track but left at a low burn.

If we went with the original plan wed be mostly renewable and much cheapr now, but well conservatives and "liberals" always need to fuck things over in favor of fossil industries like nuclear.
