Earth Hour - March 29th 2008 - Get ready to turn out the lights

Started in Sydney in 2007 this year Earth Hour, in which entire cities turn out their lights, goes global.

Notably no English cities are listed, probably a good thing after the flop that was Energy Saving Day, but even if you live in a city that hasn't signed up you can still turn your lights off and ask your employer to do the same for an hour at 8pm on March 29th.
