Stats on wikipedia [1] stopped breaking out coal from other fossil fuel ('thermal') production in 2021.

But coal was 4.1 million GWh in 2014 and 5.0 million GWh in 2021; that's a lot of (relatively) new coal. Fossil fuel growth since 2023 is a lot less than earlier years, so maybe they have hit saturation for fossil fuel generation. I would expect high fossil fuel prices so far this year would drive usage lower, the stats for 2026 should be interesting.
