They are also increasing coal usage, you are correct, however in the past 2 years, their solar output has increased significantly, to the point where it increased more than their coal output in 2024.
My point is that the comment you are quoting is actually technically correct, if you compare 2023 and 2024 in that graph for example, solar was the largest increase in output.
And unless people are shoveling coal directly into the data centres this electricity generating gas turbine is intended to be used for the electricity generation mix is more appropriate to conapre:

I mean... Seems obvious, no?
Even if we give China the most charity and take their 2025 results at face vault(even though they NEED to be independently verified) China is at best average when it comes % of gridpower that is renewable. Off the top of my head I think they are like 27-30% renewable. But its actually worse because they are the biggest polluter by a mile. Bigger the next 6 biggest polluters combined.

The coal line was slightly under the previous year’s and is now overlapping i.e. no growth compared with last year (data up to October)
That graph shows production, not capacity, nor installed capacity in each year.
Solar capacity and say nuclear / coal / gas / hydro / fuel oil capacity
Are different beasts.
When solar advocates bang on about adding X gigawatts of capacity, they’re being dishonest. What they really mean is they added X/4, because, obviously, it’s sunny only about 25% of the time throughout a year.
Adding batteries doesn’t change that. Still have to over build.
So let’s focus on the numbers that reflect actual production, so we can have an honest conversation.
Nuclear / coal / gas / hydro / fuel oil, even biomass have capacity factors typically about 80%, often about 90%.
Wind and solar are never going up ro those capacity factors, even with batteries (including pumped hydro).
Have you considered working for the IEA?
On the contrary, check out this graph:

Solar is a tiny portion of new energy capacity in China compared to coal, oil, and gas. But it is similar to nuclear as of 2024. New coal production swamps everything else combined.
