China mined more coal in 2025 then ever, but burned less in coal plans. Coal is slowly shifting from electricity production to synthetic oil and chemical production.
Would you mind sharing your source? AFAIK the coal plants are only backups, so it'd be very surprising if they're utilized as much as the solar capacity.
Which is easy to do when you live an authoritarian state with plenty of vast desert wastelands to erect solar/wind farms. Was there a village there last week? Not anymore, it was in the way. And best of all they can build it all with Uyghur forced labor. Accolades for China all around!
