Solar power program yields mixed results in Tibet

Due to its high altitude and vast open space, the Tibetan Plateau receives more than 3,000 hours of sunlight every year. The Chinese government has been pushing to advance solar energy in the region since the 1980s. But its efforts came in fits and starts. And, as FSRN'S Yanmei Xie reports, the spread of solar panels has its environmental problems as well.
