There's an episode of Today's Homeowner that's all about ways to be more energy efficient in your home. I found it at www.zipidee.com at this link: http://www.zipidee.com/zipidPreview.aspx?vid=69a14152-b602-4c19-96a7-452ab49d5d4a You ahve to pay $1.99 for the whole thing, but it looks good. They have a bunch of episodes of the show available.
