China has more solar energy capacity than any other country in the world, at a gargantuan 130 gigawatts. If it were all generating electricity at once, it could power the whole of the UK several times over. China is home to many sizeable solar farms – including the huge 850-megawatt Longyangxia Dam facility on the Tibetan Plateau, with its four million panels. And the largest solar plant in the world at the moment is in China’s Tengger Desert – its capacity exceeds 1,500 megawatts.
