It's always tough talking about installed capacity, because renewables have to be discounted so much. Solar is only about 1/5th of installed vs productive capacity. Yearly amount generated is a lot easier to compare.
But still, as your graph shows, coal is increasing in absolute numbers, and I don't really see how it decreases in absolute numbers for a long time going forward. But the reality is, the only important bit is emissions generated by the sector per year, I'm not really sure it matters where those emissions come from. And by averaging over a year, you smooth all the demand and generation issues and can have a good idea of the trend.

So growth is still ~ 1% per year, though probably higher given 2022 was probably a bit pandemic constrained still. Particularity in China. Like I said, I'll believe it when I see a few years of it.
