The photovoltaic power station in Talatan not only provides clean energy, but also attracts herdsmen to return, creating a cycle of activity that improves the ecological environment on the Gobi Desert. "It kills three birds with one stone," says Zhang Zhenfei, director of the energy bureau of Hainan Tibetan autonomous prefecture. "The current Talatan not only has an average annual power generation of 80 million kilowatt-hours, but also achieves a 50 percent reduction in wind speed in the park, a 30 percent reduction in soil moisture evaporation, and a recovery of vegetation coverage of 80 percent. With the desertification of the land curbed, the annual output of pasture has reached 110,000 tonnes, and the number of 'photovoltaic sheep' has reached more than 20,000."
