This is another total distortion.
In 2024 China produced 53% of its energy from coal, 17% from oil and about 8% from gas. That is nearly 80% from fossil fuels, and if you add in the burning of waste, you certainly get to that figure. Last year they built 40 Gwatts of NEW coal power generation.
They burned FOUR BILLION TONNES of coal last year!
Oh - and by the way - the
If you put the 260 Gwatts of new green Chinese power against the legacy 3,349Gwatts of mostly high carbon Chinese power generation, the new stuff is a spit in the ocean.
Take into account that UK electric power emits 135 grams of co2 per kilowatt hour and Chinese power emits 582 grams of co2.
You regularly whitewash Chinese emissions. I have no idea why. I can't work out why anyone would do that.
Oh - and by the way - the focus on the frequency of teh grid is NOT a bureaucratic fixation on a magic number. The reason the frequency is kept up is that it means the total of the generation being put into the grid matches the demand. If the frequency goes to 51 or 53 HTZ, it means there is too much generation and the voltage on teh grid and in teh transformers and in the sockets in your kitchen goes up and is well out of specification. The turbines are rotating faster than they ought to be and if it goes much further they will run away unless throttled back. If it goes the other way and falls down to 48, or 47, the load on the grid is higher than the generation being put in and the load increases so much that the giant rotating turbines have slowed down.
As for renewables being better at managing load variations than the inertia of rotating mass - it isn't, and you were saying the opposite two days ago.
