If you have a young child in your family, they might enjoy this free Lorax energy saving activity book from Energy Star. It's only six pages, but it's free and will help them learn about saving energy, such as turning out the lights when they leave a room. Just make sure you don't accidentally order them the wrong freebie. Chances are they won't find “Putting Energy into Profits: ENERGY STAR Guide for Small Business (2007 version)” nearly as interesting.
