Globally interconnected solar-wind system addresses future electricity
Here, we outline an optimized, phased pathway for integrating solar and wind energy into a globally interconnected and fully coordinated power system.
The results reveal that wind energy and solar energy resources in China undergo large interannual fluctuations and show significant spatial heterogeneity. At the same time, according to the complementarity of wind and solar resources, over half of China's regions are suitable for the complementary development of resources.
China's solar and wind operating capacity has soared to 1.4 TW and now accounts for 44% of the world's operating utility-scale solar and wind capacity, more than the combined total of the European Union, United States, and India.
China is advancing a nearly 1.3 terawatt (TW) pipeline of utility-scale solar and wind capacity, leading the global effort in renewable energy buildout. This is in addition to China's already operating 1.4 TW of solar and wind capacity, nearly 26% of which (357 gigawatts (GW)) came online in 2024.
In the quest to scientifically develop power systems increasingly reliant on renewable energy sources, the potential and temporal complementarity of wind and solar power in China's northwestern provinces necessitated a systematic assessment.
