This handout satellite image from Copernicus Sentinel Data 2025 taken on October 31, 2016 and received on July 29, 2025 shows fields of solar panels at the National Energy Solar Power Power Generation Technology Research and Development Center - Qinghai Test Base, in the desert at Delingha, in China's northwest Qinghai province. An ocean of blue solar panels ripples across the ochre dunes of Inner Mongolia's Kubuqi desert, a glittering example of China's almost inconceivably mammoth energy transition. Even as other countries have put the brakes on desert solar projects for economic or technical reasons, China -- the world's largest emitter of greenhouse gases -- is ploughing ahead.
