Light pollution could power solar panels

Light pollution is so bad in London at night that it can power solar panels, experts have said.

The growth of illumination from neon signs, office blocks and transport networks is creating a permanently lit world that is damaging human health and wildlife, and blocking out the night sky.

Kerem Asfuroglu, a dark sky advocate from lighting specialist Dark Source, said cities could become so light polluted that people might need to carry umbrellas to shade themselves from the glare.
