How the lists work
Each list ranks only the current ENERGY STAR certified models that publish an annual energy figure. Where ENERGY STAR gives an efficiency rating that already allows for size, such as a uniform energy factor or a percentage below the federal standard, that rating decides the order. We do not test products and we do not show retailer prices. Read the methodology.
