Earth Hour is Tonight, March 28, at 8:30 p.m.

Celebrate Earth Hour Tonight by Turning the Lights Off

Earth Day is coming up, but before then I hope you're participating in Earth Hour, which takes place tonight at 8:30 p.m. until 9:30, no matter where you are or what time zone you're in. Earth Hour is an effort by the World Wildlife Foundation, and all you have to do to participate is to turn your lights off.

The goal is for 1 billion people to go dark, thereby "voting earth" and making an impact as a united planet.

So far, everyone is voting yes to turn out the lights, and if you care to make it geeky, Earth Hour encourages you to blog about it and tag it with earthhour or voteearth, and your location, or Twitter about it and add #earthhour or #voteearth and your #location in your update.
