China has advanced a 7 GW solar project spanning 610 square kilometers on the Tibetan plateau, with two-thirds of panels installed and power already supplied to households. Solar generation has overtaken hydropower and is set to exceed wind as the country’s largest clean energy source. Key challenges remain in transmitting electricity from western regions to eastern industrial centers and in adapting the grid, designed for coal-fired output, to accommodate variable renewable supply. Carbon emissions has fell 1% in the first half of 2025 compared with the same period in 2024, supported by 212 GW of new solar and 51 GW of wind capacity added from January to June.
