Earth Hour is coming up March 29, 2008 and cities, businesses, and individuals around the world will turn off lights for 60 minutes (8-9pm local time) "to deliver a powerful message about the need for action on global warming."
Businesses and cities can get involved by turning off non-essential lighting during this 60-minute initiative. For futher suggestions on what your business can do for Earth Hour, read "How Your Business Can Support Earth Hour 2008." For this year's Earth Hour in the U.S., Chicago is serving as the flagship city, with Atlanta, Phoenix, and San Francisco serving as partner cities.
Earth Hour started in Sydney Australia last year. During the inaugural Earth Hour event, 2.2 million people and 2100 Sydney businesses turned off their lights for one hour resulting in at 10.2% reduction in energy consumption for the hour, which is equivalent to taking 48,000 cars off the road for a year.
