The point is that the shut-down in nuclear did not increase the use of coal (the reduction in nuclear production was more than ameliorated by increased renewables supply). That was my initial point of rebuttal from the top-level comment. The use of coal increased for reasons independent of the shut-down of nuclear and mainly because export of cheap coal energy became more profitable, as argued in the linked article. So the public policy failure was in letting CO2 price allowances fall. The linked article also states the aim of the Energiewende has always been to transition away from both coal and nuclear (fission at least) to 100% sustainable energy production.
