@sheogorath So for example France did just that using nuclear and renewables. Their energy related CO2 emissions are below 100 gCO2eq/kWh - last week they were below 50 even.

Germany scared itself to death with nuclear, and closed still operational plants, switching instead to coal and fossil gas. Their emissions are usually 3-6x worse than France.

In terms of decarbonization, France closed its last coal plant in 2007, while Germany just *opened* a new one thus year.
