Germany trading nuclear for coal in 2022, and the role of the Greens supporting it, was widely reported by credible outlets; see for example [1]:
With little natural gas supplies of the country’s own, and its heavily supported renewable sector unable to fully make up the shortfall, German leaders faced a dilemma. To maintain enough gas reserves to get the country through the winter, they could try to put off the closure of Germany’s last three remaining nuclear reactors, which were scheduled to shutter by the end of 2022 as part of Germany’s post-Fukushima turn against nuclear power, and even restart already closed reactors.
Or they could try to reactivate mothballed coal-fired power plants, and make up some of the electricity deficit with Germany’s still-ample coal reserves.
[...]
Last week, the country’s parliament, with the backing of members of the Green Party in the coalition government, passed emergency legislation to reopen coal-powered plants, as well as further measures to boost the production of renewable energy.
I acknowledge that the politics and history of the nuclear decommission is more complicated than I understood - [2] seems to be a useful walkthrough. But it all happened with Green support and is the fruits of decades of Green ideological advocacy.
