I found out this afternoon (Sat. the 28Th of March) that there is to be set aside an hour, 8:30 P.M. this very day, where everyone on the earth are asked to turn off their lights for just one hour (yes, that includes computers and TVs!) Sit outside and look at the stars, no wait, it's not quite dark enough here for star gazing. Spend time with your family and friends and discuss other ways that we can make a difference in this world-wide problem of global warming. I think it will be interesting to see how many people participate, and how much is saved by just one hour of blackout. I don't think there is a way to measure this for the whole world, but it will knock off some of your own electric bill. Maybe make it a weekly family project, to come up with different ways to increase energy efficiency while we spend one hour of our time a week NOT "burning the midnight oil."
