The best way to get a handle on your home energy usage is to schedule a home energy audit. An audit can help you determine how much energy you use, identify problem areas where you might be losing energy, and plan necessary energy-saving improvements. You can find a professional energy auditor in your area by consulting either RESNET or the Building Performance Institute. If you prefer to go the DIY route, you can perform your own energy assessment with the help of this handy step-by-step guide from the U.S. Department of Energy.
