The NY Times has a great article on the lazy man's guide to saving energy. Since I feel guilty every time I change a diaper or send another bag full of unread catalogs into the recycling bin, I'm going to adopt a few of author Andew Postman's suggestions. And I've already got him beat in the compact florescent lightbulb and programmable thermostat departments! Heck, we all sleep better in the cold (and our heat is programmed to kick in at 5:30, just in time to warm things up before we throw off our down comforter).
Now I just need to convince Josh to switch off the basement lights when he comes upstairs and help me remember to shut down all of our "energy vampires" before we head to bed.
