Earth Hour swept the globe Saturday, with people and businesses urged to turn off the lights from 8:30 p.m. to 9:30 p.m. local time.
Chicago was named the 2014 US Earth Hour capital in honor of the city’s efforts to fight climate change. Chicagoans are urged to flip off the power tonight for one of the world’s largest environmental awareness events.
