State Energy Company of China Three Gorges New Energy Co. built and partially launched on a flooded coal mine in Huainan County a floating solar farm for 150 MW, which will become the largest in China. The construction of a $ 151 million facility began in July. The station is already partially connected to the power grid, but the final completion of work is planned in May 2018. Working at full capacity, it will be able to provide electricity to 94,000 homes. This project took away the title of "the largest in the world" from another floating farm in China in the same Huainan - a 40-megawatt station owned by Sungrow Power Supply Co. , which is also located on the site of the former coal mine. In total, the Okrug, as of 2008, provided 20% of the country's coal needs.

Among other countries that try to keep up with China in the development of solar energy, it also shows interest in turning coal mines half a century old in a power plant from renewable sources Germany. This is the Prosper-Khanel field in the Ruhr area, which will be closed at the end of 2018. The depth of its mines reaches 600 m, and after the conversion the power of the station will be 200 MW. Thus, it will provide North Rhine-Westphalia with net energy by 30%.
