NOTE: The federal government has imposed and updated appliance efficiency standards through several legislative acts,* and now has standards in place or under development for 30 classes of products. In general, states which had set standards prior to federal action may enforce their own standards until the federal standards take effect. States that had not set standards prior to federal action must use the federal standards. This summary addresses (1) state appliance standards that will be in place until the federal standards take effect and (2) products for which the federal government is not currently developing an efficiency standard. Much of the information in this summary comes from the Appliance Standards Awareness Project (ASAP). Visit the ASAP web site and the U.S. Department of Energy's Appliance and Equipment Standards site for comprehensive information about appliance standards.

On May 1, 2019, the Hawaii House of Representatives passed HB556 DC1, codifying new water and energy efficiency standards effective on January 1, 2021. Additionally, the state is phasing out the sale of fluorescent lighting. Screw-base CFL bulbs will be phased out on January 1, 2025, and pin-base CFL and fluorescent tubes will be phased out on January 1, 2026. Products with new or updated energy standards, without federal preemption are listed below:

  • Computer and Computer Systems
  • High-CRI Linear Fluorescent Lamps

These provisions do not apply to: new products manufactured in the State and sold outside the State; new products manufactured outside the State and sold at wholesale inside the State for final retail sale and installation outside the State; products installed in mobile manufactured homes at the time of construction; products designed expressly for installation and use in recreational vehicles.

* These acts include the National Appliance Energy Conservation Act of 1987, the Energy Policy Act of 1992, the Energy Policy Act of 2005, and the Energy Independence and Security Act of 2007.
