According to a new analysis published on Carbon Brief, clean energy generated a record-high 44% of China’s electricity in May 2024, pushing coal’s share down to a record low of 53% despite continued growth in demand.
Based on official figures and other data, the analysis said that coal lost seven percentage points compared with May 2023, when it accounted for 60% of generation in China.
In May, solar power accounted for 12% and wind power for 11% of China’s electricity generation, thanks to significant new capacity additions.
Hydropower contributed 15%, nuclear 5%, and biomass 2% of the non-fossil fuel-based power.
This surge in renewable energy generation resulted in a 3.6% reduction in carbon dioxide emissions from the power sector, constituting approximately 40% of China’s total emissions.
Lauri Myllyvirta, the report’s author, added, “If current rapid wind and solar deployment continues, then China’s CO2 output is likely to continue falling, making 2023 the peak year for the country’s emissions.”

Additionally, the analysis showed solar power generation soared by a record 78% year-on-year in May to 94 TWh.
Data from China’s National Bureau of Statistics showed a 29% increase, but that excluded rooftop solar panels and, therefore, missed about half of the electricity generated by solar energy.
The Carbon Brief analysis estimated wind and solar output by utilizing power-generating capacity data and utilization figures provided by the China Electricity Council, an industry association.
It said the wind power generation increased by 5% year-on-year to 83 TWh, despite a 21% increase in capacity being tempered by reduced utilization due to varying wind conditions.
Hydropower generation also saw a 39% increase compared to last year, when drought conditions had adversely affected hydropower plants.
