Thank you for your reply. I was not aware of that. However I do think that there is a nuance between a selling natural gas product (for heating) vs. electricity produced with natural gas. Greenpeace did the former, because there was/is no way to get enough green gas at the moment. I think this is legitimate, because at the moment that’s the case for every natural gas provider. Then in the future they can transition with their already client base. To be clear Greenpeace never sold non-renewable electricity.

Nonetheless is extremely disappointing that it takes so long and I also understand if current customers feel betrayed.

Does anyone know if there is a better natural gas provider with a higher percentage of green gas in the mix?

This is simply not true. The shutdown of all nuclear plants (second attempt) has been decided by the CDU after Fukushima. The last government where the Greens were part of actually postponed the shutdown for a couple month because of the energy crisis cause by the war in Ukraine.

Germany also decided to shutdown all coal power plants until 2038. Yes, Germany has historically a lot of coal power plants, but the future is renewable. Let me remind you that my comment was in response to someone saying the oil industry started the grass roots anti-nuclear movement.

Here ist good chart of Germany‘s energy mix:

Source? Most if not all in “anti-nuclear crowd“ (in Germany) are also against the burning of fossil fuels. Instead they really like renewable energy like solar or wind. See the history of the German Green party for reference which was founded out of the anti-nuclear grass roots movement and they are also opposed to the burning of fossil fuels. I don‘t know if that‘s different in other countries.
