Microsoft has a great free web-based service that lets households track their energy usage and offers home specific tips to reduce power usage in your home. The Microsoft “Hohm” uses algorithms developed by the Lawrence Berkley National Laboratory and the US Department of Energy to help users find out where they can make changes and improvements in their home to reduce energy usage.
Once you sign up you begin the survey by answering questions about your home and about your energy usage. So far the service is still in beta, but it is worth checking out. Another great way to save on energy consumption.
