BEIJING, May 16, 2024 — Forget incremental change. China is building out clean energy infrastructure—solar, wind, and the grid connections to support it—at a speed and scale the world has never seen. The country added a staggering 290 gigawatts of wind and solar power capacity in 2023 alone, enough to power nearly all of Texas.

China’s clean energy deployment is reshaping the global energy landscape, raising questions about its impact on climate goals and geopolitical dynamics.
- China added 290 gigawatts of wind and solar capacity in 2023.
- The country’s renewable energy capacity now exceeds that of the entire European Union.
- This rapid expansion is driven by both climate goals and economic opportunities.
- Challenges remain in integrating renewables into the grid and managing intermittency.
What is driving China’s remarkable expansion in clean energy? China’s commitment to renewable energy is fueled by a desire to reduce its reliance on coal, address severe air pollution, and become a global leader in green technologies.
The Scale of the Transformation
The sheer volume of new clean energy projects is breathtaking. In 2023, China’s wind and solar capacity increased by 66 percent, dwarfing additions in other countries. By the end of 2023, China’s total renewable energy capacity—including hydro, wind, solar, and biomass—reached 2,678 gigawatts, surpassing the entire European Union’s capacity. This includes 685 gigawatts of wind power and 602 gigawatts of solar power.
Beyond Generation: Building the Grid
Adding renewable energy sources isn’t just about erecting turbines and laying down solar panels. It requires a massive investment in grid infrastructure to transmit the electricity from remote areas—where wind and solar resources are often abundant—to population centers. China is responding with a build-out of ultra-high voltage (UHV) transmission lines, capable of carrying vast amounts of electricity over long distances. As of the end of 2023, China had over 35,000 kilometers of UHV lines in operation.
Challenges and Considerations
Despite the impressive progress, integrating such a large amount of intermittent renewable energy into the grid presents challenges. Ensuring grid stability and managing fluctuations in wind and solar output require advanced forecasting, energy storage solutions, and flexible power sources. The country is also grappling with curtailment—the practice of shutting down renewable energy facilities when there isn’t enough demand or transmission capacity. In 2023, wind curtailment rates were 8.6 percent, and solar curtailment rates were 3.6 percent.
The rapid expansion of clean energy in China has significant implications for global climate goals and the energy market. It demonstrates that a rapid transition to renewable energy is possible, but also highlights the need for substantial investment in infrastructure and technological innovation. The country’s dominance in the clean energy supply chain also raises questions about geopolitical dependencies and the potential for trade tensions.
