On-Line Energy Audit Tool for Fanatics

Want a “real” energy audit, but don’t want to pay for it? Introducing the Department of Energy’s Home Energy Saver! It’s a very intense energy simulator that takes into account the shape and square footage of your house, how many windows you have, shade trees, you local climate, the direction your house faces, the age of your appliances…everything! The site then suggests upgrades and calculates how long it will take for energy efficient changes to pay for themselves. Very, very, very cool tool for consumers who already know the basics and want to do more. —MEGHANN MARCO

    Wow, that is one of the most amazing online tools I’ve seen come out of our government! What else do they have up their sleeves?

    After plugging in data for my grandparents’ home, which is an energy-eating monster, it was able to identify some very reasonable upgrades which could save more than a thousand dollars per year, paying for themselves within two years.
