Tonight starting at 8 PM your local time, turn off your lights. Be a part of the World Wildlife Fund's Earth Hour. All over the world people are turning off from 8-9 PM to raise awareness of global warming. Hey, it's a step!

It seems my father and grandfather would be proud. They were always going around the house, turning off lights, yelling about illuminating rooms no one was in. I find myself doing the same thing.
