The other day I found out about earth hour. You can go read about it, but I’ll give you the short version. At 8:30 P.M. turn off all your lights for one hour. They are aiming for one billion people participating this year (last year was 50 million). I’m not huge into all this ‘global warming’ stuff, but I do think we need to do a better job conserving energy, and this is one way to help make that happen.
