Now in it’s third year, The World Wildlife Fund (WWF)’s Earth Hour is once again inspiring people all over the world to switch off their lights for one hour on March 27, at 8:30pm local time, as part of a global vote for the environment.
Last year, nearly one billion people in 4100 cities in 87 countries turned off their lights. In the U.S. alone, 80 million people in 318 cities participated. Several cities, including Washington, DC, and landmarks from around the world also participated, including the Empire State Building, the Eiffel Tower, the Great Pyramids, Broadway Theatre Marquees and the Las Vegas Strip (imagine how much electricity was saved from these last two locations alone).
And Commonwealth Edison in norther Illinois reported that electrical usage dropped by 1 percent during Earth Hour 2009. This saved about 100 megawatt hours of electricity, which is equivalent to the removal of around 154,000 pounds of carbon dioxide from the atmosphere.
For specific actions you can take as an individual, organization or government, see the Earth Hour toolkit page. Today I signed the pledge to participate, and you can too by visiting the Earth Hour website.
If you are wondering what to do during that hour of darkness, here is a family-friendly list of ideas for activities from Mother Nature Network.
