Photo taken on Sept. 14, 2020 shows a photovoltaic power base in Kubuqi Desert in Ordos of north China's Inner Mongolia Autonomous Region. Kubuqi Desert, located in the Ordos plateau, has an area of about 18,600 square kilometers. Once being totally barren and was called the "sea of death", the desert, however, now has a green area of more than 3,200 square kilometers thanks to the efforts of local people, enterprises and government. In 2014, The United Nations Environment Program (UNEP) announced that Kubuqi Desert is an ecological economy demonstration zone, showing the experience and wisdom of Chinese people in the action.
