Check your home's energy usage
Improve efficiency and lower your bills
This free online home energy audit quickly computes your home's energy usage based on methods developed at Lawrence Berkeley National Laboratory. By changing one or more features of the model home to match your situation, you can estimate how much energy and money you can save by making energy-efficient improvements. It covers heating, cooling, major appliances, lighting, and some miscellaneous areas.
The home energy audit calculates your use and savings opportunities based on a detailed description you provide of your home. The more specific you can be when inputting information, the more accurate your results are likely to be. However, we make no warranties about accuracy nor promises on savings because your actual electric usage includes other variables.
