Sorry for the late post on this, Earth Hour happens today at 8 pm in your local time zone! To participate, this means that you need to turn off all non-essential electrical devices in your home.

I wrote about an event similar to this in San Francisco, Lights Out SF, previously. This event is organized by the World Wildlife Fund and is sponsored by National Geographic, HP, and esurance.

To find out more about the event, check out their about page.
