An aerial drone photo taken on Aug. 20, 2024 shows workers setting up photovoltaic panels at a clean energy industrial park in Majiatan County of Lingwu City, northwest China's Ningxia Hui Autonomous Region. Ningxia's favorable terrain, robust power grid, and stable output have made it a vital hub for China's west-to-east power transmission program, supplying electricity to over 10 provinces including Shandong and Zhejiang. Lingwu is rich in coal resources. Over the years, some coal mining areas have been left behind by mining activities in the city. The photovoltaic bases have utilized the barren hills and slopes that feature mining-subsidence and goaf areas, infusing them with new vitality.
