China's Renewable Energy Surge: A Global Game Changer

China is rapidly advancing its renewable energy capacity, with 64% of global wind and solar projects under construction there. This development is driving coal's share of electricity generation to new lows. As China surpasses its 2030 renewable targets, it's crucial to improve transmission infrastructure to absorb the green energy boom.

Nearly two-thirds of major wind and solar projects currently under construction worldwide are in China, according to research released on Thursday. This significant renewable capacity growth has drastically reduced coal's share of electricity generation. China is building 339 gigawatts (GW) of wind and solar capacity, representing 64% of the global total, as per a report by U.S.-based think tank Global Energy Monitor (GEM). This figure is more than eight times the project pipeline of the U.S., which stands second with 40 GW.

The rapid pace of China's renewable energy development positions the global goal of tripling renewable capacity by 2030 as achievable, even without additional hydropower, according to the report's authors. They urged China to enhance its climate targets at the U.N. next year. Furthermore, Beijing is expected to meet its 2030 goal of installing 1,200 GW of wind and solar six years ahead of schedule, as noted by Climate Energy Finance.

However, integrating this surge in renewables into China's coal-centric grid presents challenges. Faster transmission line development is essential, said GEM research analyst Aiqun Yu. Nevertheless, the new capacity has already driven renewable energy generation to record highs, according to an analysis published by Carbon Brief. In May, China generated 53% of its electricity from coal, a record low, while 44% came from non-fossil fuel sources. This shift suggests that China's carbon emissions may have peaked last year if the trend continues.
