The ENERGY STAR® Emerging Technology Award (ETA) is given to innovative technologies that meet rigorous performance criteria to reduce energy use and lower greenhouse gas emissions. The U.S. Environmental Protection Agency (EPA) is pleased to recognize Residential Induction Cooking Tops for the ENERGY STAR Emerging Technology Award for 2021.
Products that meet the performance criteria (PDF) will be listed on a Qualified Product List (PDF) once it is determined that all Award criteria have been satisfied. Manufacturers can submit documentation for eligible residential induction cooking top products to EmergingTech@energystar.gov
Benefits of ENERGY STAR Emerging Technology Award-Winning Systems:
Conventional residential cooking tops typically employ gas or resistance heating elements to transfer energy with efficiencies of approximately 32% and 75-80% respectively. Residential induction cooking tops instead consist of an electromagnetic coil that creates a magnetic field when supplied with an electric current. When brought into this field, compatible cookware is warmed internally, transferring energy with approximately 85% efficiency. Furthermore, because the source of heat is the cookware itself, the cooking top surface remains cool to the touch and less heat is lost to the surrounding air, providing an additional energy efficiency benefit by reducing the workload for the HVAC equipment. A cooler cooking top surface also makes induction cooking tops safer to work with than other types of cooking tops. Finally, because the cookware itself is the source of heat, it reaches desired temperatures more quickly and provides faster cook times.
The per unit efficiency of induction Cooking Tops is about 5-10% more efficient than conventional electric resistance units and about 3 times more efficient than gas. If all Cooking Tops sold in 2021 in the U.S. used induction technology and met these draft criteria, the energy cost savings would exceed $125 million and the energy savings would exceed 1,000 GWh.
Winning Products Must Demonstrate That They:
- Meet the Department of Energy (DOE) definition for built-in, drop-in or freestanding Cooking Tops and be intended for residential use.
- Only include induction heating technology for all surface units on the cooking top.
- Are tested to have an Integrated Annual Energy Consumption (EIAEC) ≤ 125 kWh/year.
- The energy measurements are performed at an ISO/IEC 17025 accredited lab and documentation of the lab accreditation is included with the Emerging Technology Award application. (Alternatively, documentation that the lab is approved by one of the EPA-recognized accreditation bodies will also satisfy the Emerging Technology Award requirements, but it is not necessary.)
- Are approved for use and available for sale in the U.S. market.
