An anonymous reader quotes a report from Digital Trends: Not only is it the world's most populous country, it's now also the world's biggest producer of solar energy. On Saturday, the National Energy Administration (NEA) noted that the nation officially claimed the title after doubling its installed photovoltaic (PV) capacity last year. By the end of 2016, China's capacity hit 77.42 gigawatts, and while this is great in terms of raw numbers, it's a lot less impressive relative to the country's massive population. As it stands, solar energy represents only one percent of the country's energy output. But this may soon change as China devotes more and more of its attention towards clean energy. The NEA says that China will seek to add more than 110 gigawatts within the next three years, which could help the nation up the proportion of its renewable energy use to 20 percent by 2030. Today, it stands at 11 percent.
