Earth Hour is a yearly event where people around the world pledge to turn off the lights for an hour. Many cities and utilities are participating, too. Cities are then compared based on the power usage declines to gauge participation.
It's a really nice time to go out, as most city lights will be turned off or dimmed, depending on where you live. It was pretty nice here. :) It was kinda sad to see that immigrant lower class neighbourhoods didn't seem to care much about it, everyone having their lights on while I passed by. :| The nicer places had much more participation.
Landmarks around the world are dimmed, which looks pretty cool, too. You can find photos all over the 'net.

So, will you be taking part in this, tonight? If so, how will you pass the time without your lights/computers/etc? :P
