Solar farm transforms China's largest open mining wasteland 【Voice_over】 In north China's Inner Mongolia Autonomous Region, a solar farm built on an abandoned open-pit mine dumping site was recently connected to the grid. Mine dumping sites are vast expanses of land that contain waste materials from coal or ore mining processes and are otherwise unuseable after mines are closed. Experts say erecting solar farms on the barren land will reduce water evaporation and further the country's efforts to transform its mining industry. 【Sound_bite】 Shen Hongfa, head, Baiyinhua Electric Power Plant, Inner Mongolia branch, State Power Investment Corporation: "Installing photovoltaic panels on mining wasteland can not only reduce the evaporation rate of the wasteland's surface water by 20 to 30 percent, but can also effectively reduce the wind speed and improve the habitat for vegetation." 【Voice_over】 According to its developer, China's State Power Investment Corporation, the project is expected to generate 450 million kilowatt hours of electricity annually, when fully operational.
