We're talking about whether keeping the nuclear plants on would have made Germany independent of Russian gas. If we had heat pumps everywhere we might as well use renewable energy, that's cheaper than nuclear.
For power generation, lignite and coal stayed about the same, gas increased from 20 to 30, oil stayed about the same. The only thing that went significantly down was nuclear going from 22.4 to 8.1.
It all depends on where your priorities are, and obviously getting rid of nuclear was more important than burning Russian stuff into the atmosphere.
Your chart shows installed capacity, which is different from total power output. For gas plants in particular, since they are used as peaker plants with low capacity factors. In 2021 only 12% of the natural gas consumed in Germany was turned into electricity. In 2011 it was 14%.
Let's face it, we're in this shit because of political shortsightedness, not because it was the best way to go.
