Accelerate the World's Transition to Sustainable Energy - to fight Anthropogenic Climate Change, page-35599

To "firm" or stabilise the supply of power from its renewable energy zones, China is using a mix of pumped hydro and battery storage, similar to Australia.

"They're installing 1GW per month of pumped hydro storage," Mr Buckley said.

China installed 1GW of nuclear last year, compared to 300GW of solar and wind, Mr Buckley said.

"That says they're all in on renewables.

"They had grand plans for nuclear to be massive but they're behind on nuclear by a decade and five years ahead of schedule on solar and wind."

A report by Sydney-based think tank Climate Energy Finance (CEF) said China was installing renewables so rapidly it would meet its end-of-2030 target by the end of this month — or 6.5 years early.
