Achieving Efficiency

Hawaii’s overall goal for energy efficiency is to reduce electricity consumption by 4,300 gigawatt-hours by 2030.  To meet this goal, the state will continue to:

  1. Align the efficiency regulatory policy framework with clean energy goals;
  2. Support the retrofitting of existing residential and commercial buildings;
  3. Strengthen new construction policies and building codes;
  4. Identify non-building related energy efficiency measures.


Looking ahead, there are vast opportunities for new gains in energy efficiency. Hawaii aims to maximize efficiency through technology, building practices, retrofits, and consumer behavioral change.

As of January 1, 2015, Renewable Portfolio Standards reporting by law no longer includes Energy Efficiency Portfolio Standards (EEPS). Under HRS 269-96, relating to energy efficiency portfolio standards, the Public Utilities Commission is responsible for establishing EEPS that will maximize cost-effective energy-efficiency programs and technologies. This graph shows EEPS levels from 2008-2014. The EEPS requires that by 2030 annual energy savings amount to 30% of annual electricity sales statewide. An Energy Efficiency Potential Study, initiated by the Public Utilities Commission, indicates that there is the potential of exceeding this goal by 50% by 2030.
