U.S. Energy Star Appliance Standards: Details and Practical Compliance Under the DOE Transfer

ENERGY STAR's product-specific specifications for appliances and home electronics rate the energy efficiency of refrigerators, freezers, TVs, air conditioners, and other major sources of household electricity consumption, and constitute one of the United States' most important energy labels for reducing consumer utility costs and easing the load on the electrical grid as part of decarbonization efforts.

For household refrigerators and freezers (Refrigerators v5.1), standard-size units (7.75 cubic feet or larger) must demonstrate an energy-efficient design that reduces energy (power) consumption by at least 10% below the Federal Standard minimum energy efficiency requirement, with compact models and certain built-in coolers required to achieve energy savings of up to 20%–30%. For television products (Televisions v9.1), products must meet strict On Mode power consumption limits calculated based on screen size and display resolution, and must limit standby (Sleep Mode) power consumption to 0.5W or less under normal functionality, and 2.0W or less even with smart functions (such as Wi-Fi) enabled.

In the U.S. market, the presence or absence of the ENERGY STAR certification mark (the blue label) is a decisive factor in consumer purchasing decisions and brand image; products without the mark risk reduced placement at retail chains (Home Depot, Best Buy, etc.) and exclusion from cash-back and rebate programs offered by electric utilities across the country for energy-efficient appliance purchases. The program was established by EPA in 1992 and has long been jointly administered by EPA and DOE, but since June 2026 administration has been transferring to DOE. While the standard-setting and certification process itself remains unchanged, the point of contact and administrative structure are expected to shift to being DOE-led going forward.
