This comparison really exaggerates the differences, the measures are basically the same. If you look at the ranges over 2015-2020, France ranged from 0.17:0.25

This comparison really exaggerates the differences, the measures are basically the same. If you look at the ranges over 2015-2020, France ranged from 0.17:0.25 and Germany ranged from 0.14:0.46. Top 11% in 2020 vs top 14% of countries with data. It's a moot point anyway, since renewables don't stabilize Germany's grid: coal and gas power plants (and imported electricity) do. Renewables are cheap if they are a small proportion of sources or the grid is stabilized by another source. If you need storage the cost simply explodes.
