Saturday night, we will celebrate Earth Hour by turning off all (non-essential) lights from 8:30 to 9:30 p.m.
More than 5,200 cities and towns in 135 countries worldwide switched off their lights for Earth Hour 2011. –EarthHour.org
Earth Hour raises awareness of energy consumption. More importantly, it shows you that you don’t need all the lights on all the time. So, light a candle and enjoy a quiet hour in honor of the Earth.
