Just 6.5% of German electricity was generated through coal last year.

By contrast Poland was ~90% for years and only just slipped below 50%.

If I had to guess why Poland never got any criticism for that while Germany was routinely pilloried by certain flavors of propaganda I would hypothesize that it was because Poland weren't humiliating the nuclear industry by swapping them with solar panels and wind turbines at 1/5th the price.
