If you have five minutes and your last 12 months of utility bills, use the ENERGY STAR Home Energy Yardstick to compare your home's energy efficiency to similar homes across the country and get recommendations for energy-saving home improvements from ENERGY STAR.
What you need to know to get started
* Your energy use and costs for the last year: You'll need your last 12 months of utility bills OR a 12-month summary statement from your utility company.
* Energy sources for your home: natural gas, electricity, fuel oil, propane and/or kerosene?
* The square footage of your home.
You will also need to enter some basic information about your home (such as zip code, age, square footage, and number of occupants). If you don't have your bills, contact your utility for a 12-month summary.
