Wrong and baseless. It is possible to simultaneously reduce nuclear and fossil components in the energy balance and this is exactly what is happening.

> why wouldn't they covertly finance anti-nuclear if they overtly finance pro-fossil?

Greens in Germany are established political party with clear anti-Putin positioning. Financing of political parties in Germany is transparent and has sufficient oversight, so there’s neither possibility nor any sense to covertly finance them.

> Greens are pro-environment, but don't offer substitute energy sources

Where did you get that from?
