Great but I want the same deal for the coal and gas companies that produce electricity, make them responsible for every ton of CO2 they emitted and make them responsible for removing it from the atmosphere.
In the current political climate where politicians all over the world compete on subsidizing electricity and fossil fuels to combat the recent price hikes for all poorly insulated home owners and car drivers, who knows what will happen.
That said, no reason why the original deal can't be extended to renewables, seems perfectly fair. It's to everyone's benefit that all methods of power generation be held accountable for all their costs.
Why? Built geographically decoupled production, look at past weather data and pick how many 9's up-time you want.
Then use storage and smart consumers to lower the requirements.
For national emergencies keep a fossil reserve or whatever, with that kind of usage power 2 gas should not even matter.
It's not really that great.
No, it is not the green party who is at fault. This falls fully on the shoulders CDU who was in power for 16 years.
