As a result, France's electricity grid is almost fully decarbonized (and we'd be in a better state if we didn't shut down one reactor for political reasons) while industrialized countries betting only on NREs are still counting the days they don't need to burn coal. So there are good things about it.
It’s a little more complicated as they’re importing and exporting a great deal of electricity. But overall yea it’s been good for the environment, just expensive.
