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.

Symposium on Exploring Programs and Policies for Deep Energy Efficiency Opportunities
On November 14, 2018 the Hawaii State Energy Office hosted the Symposium on Exploring Programs and Policies for Deep Energy Efficiency Opportunities. The symposium explored programs and policies that could stimulate the adoption of greater, deeper energy efficiency. Aggressively tackling energy efficiency also supports our goal to achieve 100 percent renewable by 2045.
