You can also decide to look at countries which went 100% renewable and have even better CO2/kWh rating than France (Iceland, Norway, Albania for example).

Iceland has massive volcanoes and a small population.

Norway has lots of hydropower and a a small population.

Not super familiar with Albania but they seem to be in the same situation as Norway.

France already implemented hydropower wherever it was possible years ago, so that's not an option.

Also France seems to have pretty much the same CO2 / kWh than Norway.

Yes, situations are different I agree :) my point was just that you can pick and choose what you want to look at. We'll see how things evolve, but it's not very fair to compare the situation of France which did their switch to low carbon energy many years ago, to Germany which is currently doing it. When we have more countries with finished transition to full/mostly renewable, we can compare again.

In the last 90 days France's CO2 footprint is at 78% of Iceland's.

Also, what lessons learned in Iceland, Norway or Albania should we apply in central Europe? We don't have their geothermal and hydro potential (all your examples are not solar+wind but hydro primarily).
