This chart is interesting, but doesn’t show numbers in a really useful way. The US generated 778 TWh in 2021 compared to 379.5 TWh in France in 2019 but the relative consumption really helps put these in perspective: Nuclear energy represents only 18.9% of all electricity produced in the US compared to 70.6% in France.

The US does use more nuclear than France (and pretty much any country, but I have numbers for France) but it only represents a fifth of total production as it is accompanied by more than 2.5 PWh of fossil fuels!

So, Yea, dirty, dirty America 🙈
