Chicago Codes
Earth Hour

By: Julie Davis

This March, businesses and residents around Chicago will be voluntarily turning off their lights, as a part of the World Wildlife Foundation's Earth Hour. Earth Hour is intended to draw attention to the need for daily energy conservation and the damaging effects of greenhouse emissions on the environment. Cities around the world will be turning off their lights between 8PM and 9PM local time on March 29, 2008.

The Earth Hour Initiative began on March 31, 2007 when the residents and businesses in Sydney, Australia turned off their lights for one hour. For that hour, Sydney reduced its energy consumption by 10.2%. The darkened faces of such icons as the Sydney Opera House and the Harbour Bridge caught the attention of Sydney's residents and are inspiring other cities to help raise awareness about the effects of global warming and the actions individuals and businesses can take to conserve energy and preserve the environment.

To date, Chicago and 23 other cities around the world plan to take part in Earth Hour. To learn more about Earth Hour, or to register your business or household, log on to
