Earth Hour is an international event organised by the WWF (World Wide Fund for Nature/World Wildlife Fund), and held on the last Saturday of March each year, which asks households and businesses to turn off their non-essential lights and electrical appliances for one hour to raise awareness towards the need to take action on climate change. Earth hour was conceived by WWF Australia and the Sydney Morning Herald in 2007, when 2.2 million residents of Sydney participated by turning off all non-essential lights.[1] Following Sydney's lead, many other cities around the world adopted the event in 2008.
People from 1500 cities across the world are turning off thier lights to vote for earth this time.

Earth Hour, an event created in Sydney two years ago at 7.30 pm,march 2007 by environmentalists keen to cut energy use and reduce greenhouse gas emissions.In Sydney, Australia, the end of Earth Hour was celebrated with a fireworks show.
Earth Hour has also received free publicity from the Google corporation. From 12:00 a.m. on March 29, 2008 until the end of Earth Hour, the Google homepage in the United States, Colombia, Canada, Denmark, Ireland and the UK was turned to a black background. Their tagline is, "We've turned the lights out. Now it's your turn - Earth Hour." A common misconception is that having a black background on a web page reduces the power consumption of monitors; LCD monitors use a constant amount of power regardless of which colors are shown. This is not the case for Organic LED monitors,though they are not currently in popular use.
