"On Saturday, March 27, 2010, at 8:30 p.m. local time, Earth Hour will once again cascade around the globe, from New Zealand to Hawaii.
The idea is simple, powerfully symbolic and unifying. Company facilities (excluding locations where participation will be an operational challenge) will power down office and data center lighting and signage for one hour.
Since its inception three years ago, Earth Hour’s non-partisan approach has captured the world’s imagination and become a global phenomenon. Nearly one billion people turned out for Earth Hour 2009 – involving 4,100 cities in 87 countries on seven continents. All of these iconic world-wide landmarks went dark: the Empire State Building, the Great Pyramids of Giza, Christ the Redeemer Statue in Rio de Janeiro, St. Peter’s Basilica in Vatican City, Big Ben and Houses of Parliament in London, the Eiffel Tower in Paris, Sydney’s Opera House and the Symphony of Lights in Hong Kong.
We also encourage you to participate in Earth Hour in your own home. Register as an individual at http://www.earthhour.org/ to receive tips and suggestions on how to be one of the millions of people involved in Saturday’s event.
Participation is easy. Just turn off your lights on March 27 at 8:30 p.m. local time. One simple flip of a switch symbolizes that, by working together, each of us can help to spread awareness on energy consumption patterns.
And, starting today, please remember to turn off all of your non-essential equipment as you leave the office. "
