Planet U will turn off all non-essential lighting for Earth Hour, and we encourage organizations and individuals to do the same. This will be awesome!

Earth Hour, which takes place Saturday, March 27th at 8:30 p.m. local time, is an event in which millions of Americans will turn out their lights for one hour in support of action on climate change and toward creating a cleaner, safer and more secure future. 2010 marks the third year of the event, which attracted more than 80 million participants in the U.S. last year, and nearly a billion people around the world, as lights dimmed on such global icons as the Eiffel Tower in Paris, Sydney’s Opera House, the Great Pyramids of Gaza and New York’s Empire State Building.

Notable U.S. landmarks such as Mount Rushmore in South Dakota, St. Louis’ Gateway Arch, Sea World in Orlando, the strip in Las Vegas, New York’s Empire State Building, the Golden Gate Bridge in San Francisco, Washington D.C.’s National Cathedral, California’s Santa Monica Pier and the Space Needle in Seattle are among the hundreds of sites that will turn off non-essential lighting for the hour, in what is expected to be the largest-ever call to action on climate change.

Are you willing to make the 1 hour commitment? Join here (pretty please).
