The world’s largest floating solar farm is producing energy atop a former coal mine
The Chinese city of Huainan is rich in coal—very rich. By one 2008 estimate, it has nearly a fifth of all of China’s coal reserves. Now the city has become home to the world’s largest floating solar farm. Appropriately, it has been built atop a former coal mine, which had become a lake after being flooded with groundwater. The China Daily reports that the farm started generating electricity earlier this week.
