Earth Hour, March 27

Now that you've adjusted to daylight savings time, how about switching off the lights for an hour this Saturday?

On Earth Hour hundreds of millions of people, organizations, corporations and governments around the world will come together to make a bold statement about their concern for climate change by doing something quite simple—turning off their lights for one hour. In the U.S. where we are already feeling the impacts of climate change, Earth Hour sends a clear message that Americans care about this issue and want to turn the lights out on dirty air, dangerous dependency on foreign oil and costly climate change impacts, and make the switch to cleaner air, a strong economic future and a more secure nation.



Since its inception three years ago, Earth Hour’s non-partisan approach has captured the world’s imagination and became a global phenomenon. Nearly one billion people turned out for Earth Hour 2009 – involving 4,100 cities in 87 countries on seven continents.

Last year, 80 million Americans and 318 U.S. cities officially voted for action with their light switch, joining iconic landmarks from around the world that went dark for Earth Hour, including:

Empire State Building
Brooklyn Bridge
Broadway Theater Marquees
Las Vegas Strip
