Photon Farming in the Vast Solar Fields of Northern China This is an aerial view of China's future — vast solar farms that developers hope will fuel the industrial nation, as well as cut down on its choking smog problem. This solar photovoltaic power station, the largest of its type in northwest China, is currently under construction in Xining of Qinghai Province.
