Earth Hour
Started in Sydney, Australia in 2007, Earth Hour encourages people and businesses to avoid using electricity and conserve energy for one hour. In its first year, over two million Australians participated. The campaign is going international this year.
Earth Hour is being held on Saturday, March 29 at 8:00 p.m. local time around the world. So far, over 20 international cities have pledged their support and are encouraging residents to switch off lights and non-essential household appliances. The campaign has also gained the support of almost 12,000 businesses and 200,000 individuals.
