Last year, more than 2.7 million Illinois residents turned off their lights for Earth Hour, a global initiative of the World Wildlife Fund. This year, Chicago returns as an Earth Hour flagship city, with more than 20 other municipalities across Illinois officially signed on to participate in this year’s event.

We hope that you will participate in the 2009 Earth Hour event by turning off your lights on Saturday, March 28 at 8:30 pm. For more information go to Earth Hour.
