We needed to get this shit done 10 years ago. Any delay in removing all fossil fuel emissions now is just a matter of how bad we want climate change to get, rather than preventing it. Net zero by 2050 is a fucking eternity away and is a shit goal, and all the projections that get us on track to 1.5 °C of warming have us extensively using carbon capture which is entirely unrealistic.

Existing nuclear plants in France work, they can load follow to some degree, and renewables can make up the difference with minimal energy storage. But at a certain point you have to stop investing in renewables if you have minimal energy storage and your electricity solution is working.

I am going to emphasize that last part: IF you can't get enough energy storage, and IF your energy mix is fine, you must stop investment in renewable installations. Without enough storage, the baseload+peak paradigm works, you just have to regulate it.
