I don't think that the bad behavior of one German green group is representative of all renewables proponents. Nearly everybody in the renewables space is trying to stop gas burning as quickly as possible.
What is now an issue for germany is the move away from domestic or easily replaceable fossil fuels like coal or oil in favour of gas.
