Earth%20Hour%20billboard.jpgThe reduction in electricity usage in the City of Chicago and ComEd's northern Illinois service territory during Earth Hour 2010 was estimated to be about 100 megawatt hours. The energy reduction is the equivalent of removing 124,320 pounds of carbon dioxide from the atmosphere, or planting 15 acres of trees.

To calculate the energy reduction achieved during the hour, ComEd compared its customers' electricity usage during the 8:30 to 9:30 p.m. hour on Saturday night to the preceding 7:30 to 8:30 p.m. hour.

Other participants across the state included: •Approximately 200 downtown Chicago buildings;
•the State Capitol Dome, Governor's Mansion and all State of Illinois government buildings •More than 70 colleges, universities, and secondary and primary schools •More than 12 museums•More than 10 park districts, including 250 Chicago Park District field houses and facilities.

Launched three years ago, Earth Hour has become a global phenomenon, and its non-partisan approach to linking energy use and climate change has captured the world’s imagination. Earth Hour has grown to involve over 4,000 cities in on the 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!
