National Geographic on Saving Energy

I've been away for a while, thanks to a really nasty bout of stomach flu (a quick, inexpensive way to lose weight, though not a method I'd necessarily recommend). As energy was one of the last topics I wrote about, I thought I would follow up by mentioning this article in National Geographic, March 2009. It's a very interesting article about how saving energy starts at home, and chronicles several families' attempts to lower their carbon footprint by lowering their energy use. I really enjoy National Geographic magazine, and thought this was a well-written, thought-provoking piece.
