Managed to talk about china's energy buildout _without_ mention of renewables? I think this pivot is 100% designed to get government money: - natrual gas turbine - china is scary - something something it's a race - china energy is good because no regulations, totally not because they are lapping the world on renewable buildout
China alone this year has added 221GW of Solar Energy, which is about 2x the rest of the world combined.
it's a nice pivot though - turbines are just turbines.
Turbines are useful even in a 100% renewable powered world.
Perhaps not in a 100% world, though I'll give you the point that they are useful now.
In a 100% renewable world we would not be extracting or refining oil. Natural gas (used by these turbines) is a byproduct of oil drilling. Were we not burning the oil, the natural gas might be too expensive alone.
Also, in a 100% renewable world we would (by definition) have enough generation all the time - (covered by batteries and good baseload sources) that turbine power was no longer required to cover peak loads.
It's not clear (yet) what a 100% clean energy powered world would use to cover the last couple of percent of demand when loads peak and/or variable generation troughs for extended periods.
It'll be some combination of demand management (which isn't nearly as horrifying as people make it out to be), pumped hydro, long-duration batteries like iron-air, but also possibly burning hydrogen or hydrogen-derived synthetic fuels (produced by electrolysis when hydrogen is abundant) and/or biofuels in turbines.

Particularly with the development of fracking, natural gas production is no longer a just a byproduct of oil production, and can be (and is) pursued independently. Nevertheless, I agree that we developing renewables should be our priority.
If China had "no regulations" and was building out 100% coal, no one would be worrying that China industry would have an advantage due to low electricity cost vs rest of world.
China's energy buildout is still mostly coal. Go look at the last 20 years how much energy they've added for coal vs solar. Dont fall for the "solar has increased by 500%" trap.
You’re absolutely correct.
China didn’t start adding much in the way of solar prior to about 2020, whereas they added lots of coal generation in the past 20 years.

They are replacing old coal plants with more efficient cleaner designers. National security wise they still have lots of coal to work with, while most renewable energy is generated in the west where ongoing grid upgrades are needed to use it where people live (in the east).

Coal consumption has peaked there. Solar is growing explosively.
Dont you think its a bit naive to be saying something peaked when it hasnt even been a year?

Yes and:
Recent Volts episode has great overview of China's electro-tech build out, world is at or near peak fossil fuel across all sectors and countries (with 1 notable exception), etc.
