Calculators are a great way to learn about your house and save money. Each of these calculators serves a different purpose, all to help you understand where you're using the most electricity in your house. These calculators will help show you the best and most cost effective ways for conservation and efficiency, but using your own good judgment can yield the best results. Visit our tips page to learn more what you can do.
The home and business calculators use current standard rates. If your energy comes from another supplier, your analysis may vary depending on your rate.
If you're interested in an on-site energy audit, contact a professional. They use a variety of techniques and equipment to determine the energy efficiency of your home. Equipment such as blower doors measure air leaks and infrared cameras find air infiltration and missing insulation.
