Right now, solar is a drop in the bucket for China. It represents just 1 percent of the country's total power output. However, the NEA plans to add over 110 gigawatts by 2020, giving the technology a much greater role within a few years. It'll help China increase its use of non-fossil fuel power from 11 percent now to 20 percent by 2030.

Not every country can compete with these increases, of course. Even if you discount the population advantage, China has large regions that are relatively friendly to solar farms. Still, this puts pressure on the rest of the world to up its game. Countries like the US may be seen as trailing behind, especially with policies that are bent on protecting the fossil fuel industry instead of phasing it out.
