> China is adding solar. Mostly solar. The word "solar" does not appear even once in this press release, and that seems disingenuous.

On the contrary, check out this graph:

https://ourworldindata.org/grapher/energy-consumption-by-sou...

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.

They already have well over double the US solar output (US solar output is about 750 Twh according to this source, while China's is a bit over 2000 Twh) and their YoY solar increase is about 4x the US (600 Twh increase in China vs 150 Twh increase in the US)

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.

  • It may be huge someday, but now it is niche, and a tiny fraction of new capacity. Coal is king and not about to be dethroned.

In the last year of that graph 2023-2024, the increase in solar was greater than any other source, including coal, it's 15x greater than nuclear.

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:

  • why are you fixating on 1 single year? Look at the past 10 years or past 5 years and its the complete opposite.

    • Why are they looking at the most recent year when discussing the changing trend of exponential differential growth to point out it has now surpassed others, instead of the prior years where that differential was slower and the other was still growing faster?

      I mean... Seems obvious, no?

That graph shows production, not capacity, nor installed capacity in each year.

  • Well good, those are the correct numbers focus on because:

    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).

are we looking at the same graph? if you look at the past decade or so, the "solar" slice is clearly widening the fastest
