Norway has installed auto-dimming street lights in parts of the country in hopes of decreasing its carbon footprint.
Along a five-mile stretch of a highway near Hole, Norway, outside of Oslo, LED lights dim to 20 percent when no cars, bikes or pedestrians are in the area. The five-mile stretch of energy-saving lights saves 2,100 kWH per week, which would amount to approximately 21 hours of ironing, or four hours of watching TV on a plasma screen. While it is unclear how much the installation cost, it the government will break even after just 4.5 years, according to Youtuber Bjørn Nyland.
Light-related energy saving programs have popped up across Norway, with similar auto lights being put in on the western side of the state last year. In Oslo, energy consumption has reduced dramatically since 'intelligent lighting' systems were installed in the late 2000s.
