↳ Why This Matters
This shift signifies a major step in China's commitment to reducing its reliance on fossil fuels and combating climate change, impacting global energy markets and the transition towards cleaner power sources.
Key facts
China's solar power capacity reached 1,286 GW by the end of July, surpassing coal.
Solar power now accounts for 31.5% of China's total installed electricity generation capacity.
Coal-fired capacity was 1,275 GW as of the end of June.
Coal's share of China's electricity output dropped below 50% for the first time in the first half of 2026.
Renewable energy generation increased by about 9% year-on-year in the first half of 2026.
Solar power has officially overtaken coal as China's largest source of electricity generation capacity, a significant milestone in the nation's renewable energy expansion. As of the end of July, China's installed solar power capacity reached 1,286 gigawatts (GW), constituting 31.5% of its total power generation capacity. This figure surpasses the 1,275 GW of coal-fired capacity recorded at the end of June.
Official data from earlier in July indicated that coal's share in China's electricity output fell below 50% for the first time in the first half of 2026. During the same period, electricity generation from renewable sources grew by approximately 9% compared to the previous year. Renewables accounted for 41.2% of China's total electricity generation in the first half of 2026, with wind and solar combined contributing nearly 25% of the total output.
Despite this achievement, China continues to rely on coal for industrial power and grid stability. Furthermore, recent policy shifts have led to a slowdown in the renewable energy boom, with grid constraints and increased coal generation resulting in higher curtailment rates for solar and wind power.
