Earth Hour 2008 is March 29 at 8pm
The World Wildlife Fund (WWF) and thousands of bussinesses and individuals have teamed up to support a worldwide rolling lights out initiative.
On March 29, at 8pm, thousands of cities and individuals will turn off all non-essential lights for one hour. It's difficult, on their website, to find out exactly how much of an impact this will have on energy consumption. But, hopefully, what it will do is raise awareness.
