Meanwhile Germany shut down its nuclear plants while keeping coal and natural gas around to supplement renewables. One of the biggest unforced errors I've heard of recently.

Natural gas and coal are better at throttling up and down than nuclear plants are.

So if they need to run 10% of the time, then you've still reduced your carbon output by 90%. The goal is 100%, but the remaining fossil fuel plants are not the biggest issue.

A nuclear plant would also be carbon-free, but Germany had other reasons not to want it. So it was a reasonable decision to keep the fossil fuel plants around, and shut more and more of them down over time.

No, Germany is shutting down its coal plants and reduced their usage drastically.

Poland is keeping their coal plants open by refusing to invest in quick and cheap renewables. Instead they plan to build nuclear plants for the next 20 years.
