    New research published in the journal Nature Energy suggests the country's densely polluted atmosphere is blocking the sun's rays, preventing solar panels from harvesting energy efficiently.


    FAQs about China Solar Panel Pollution

    Does China have a problem with solar energy?

    China is rapidly expanding its solar power supply, hoping to meet 10 percent of the nation's electricity needs with solar energy by 2030. But there's a problem: Severe air pollution is blocking light from the sun, significantly reducing China's output of solar energy, particularly in the northern and eastern parts of the country.

    Can solar panels help reduce smog in China?

    Air pollution in China has gotten so bad, the sun can't reach solar panels that were installed to help reduce smog in the first place, according to a new study.
