Chinese officials recently showcased a colossal solar farm under construction on the Tibetan plateau, set to become the world’s largest, sprawling across 610 square kilometers—equivalent to the size of Chicago. This ambitious project in Hainan Prefecture, Qinghai province, underscores China’s aggressive push toward renewable energy to meet its climate goals, with significant environmental and economic implications.

A study released Thursday by Lauri Myllyvirta, lead analyst at the Centre for Research on Energy and Clean Air, reported a 1% drop in China’s carbon emissions in the first half of 2025 compared to the previous year, continuing a decline that began in March 2024. This suggests China, the world’s top greenhouse gas emitter, may have peaked its emissions well ahead of its 2030 target. However, achieving carbon neutrality by 2060 requires an average annual emissions reduction of 3%, a steeper challenge, Myllyvirta noted. “China needs to get to that 3% territory as soon as possible,” he said.

Unlike past emission declines tied to economic slowdowns, this trend coincides with a 3.7% rise in electricity demand in 2025’s first half. Remarkably, solar, wind, and nuclear power growth has outpaced this demand, with China installing 212 gigawatts of solar capacity—surpassing the U.S.’s total 178 gigawatts as of 2024’s end. Solar has overtaken hydropower and is set to surpass wind as China’s leading clean energy source, with 51 gigawatts of wind power added from January to June.

Li Shuo of the Asia Society Policy Institute called this a “moment of global significance,” highlighting that economic growth can coexist with emissions cuts. Yet, he warned that China’s heavy coal reliance poses a persistent threat, urging a shift to less resource-intensive sectors.

The Talatan solar farm, already operational on two-thirds of its site with over 7 million panels planned, will generate enough power for 5 million households. Beyond energy, it has transformed the desert landscape, with panels acting as windbreaks to reduce dust, retain soil moisture, and foster vegetation, allowing thousands of “photovoltaic sheep” to graze beneath. “Enterprises generate electricity on top, grass grows below, and villagers herd sheep in between—a win-win,” said Wang Anwei, Hainan Prefecture’s energy chief.

A key challenge lies in geography: most renewable projects, including this one, are in China’s sparsely populated west, while demand centers lie in the east. Vice Governor Zhang Jinming noted, “The distribution of green energy resources is perfectly misaligned with our industrial distribution.” To bridge this gap, transmission lines connect Qinghai to Henan, with plans for another to Guangdong. However, the grid’s coal-centric design struggles with the variable output of solar and wind, requiring significant operational reforms, per Myllyvirta.

This project builds on China’s renewable dominance, following the activation of a 5-gigawatt solar farm in Xinjiang in June 2024, which spans 200,000 acres and powers millions. With 510 gigawatts of solar and wind projects underway, China is on track to meet its 1,200-gigawatt renewable target by 2025, five years early, reinforcing its role as a global clean energy leader.
