Guess what!!!.... China is now the biggest producers of solar energy

You probably don't think of China as a clean energy champion given its frequent problems with smog and continued dependence on coal power, but you may have to rethink your views after today. The country's National Energy Administration has revealed that its solar power production more than doubled in 2016, hitting 77.42 gigawatts by the end of the year. The country is now the world's biggest generator of solar-based electricity in terms of capacity -- it doesn't compare as well relative to population (Germany, Japan and the US could easily beat it), but that's no mean feat for any nation.
