Greening of China's electric power system: 2021 update

China operates the world's largest electric power system, which over the course of the 21st century has been consistently greening at the margin, even as the whole energy system and the manufacturing system it powers remain largely black. In this article we update our argument to reveal how in terms of capacity, of electricity generated and of investment, China's electrical system is continuously greening and within less than five years, would be expected to be more green than black in terms of generating capacity. We demonstrate how the sourcing of generating power from hydro, wind and sun is becoming ever more significant, outranking the contribution from nuclear.
