ENERGY EFFICIENCY
Hawai‘i’s overall goal for energy efficiency is to reduce electricity consumption by 4,300 gigawatt-hours by 2030. To meet this goal, the state aligns the efficiency regulatory policy framework with clean energy goals; supports the retrofitting of existing residential and commercial buildings; strengthens new construction policies and building codes; and identifies non-building-related energy efficiency measures.
Looking ahead, there are vast opportunities for new gains in energy efficiency. Hawai‘i aims to maximize efficiency through technology, building practices, retrofits, and changes in consumer behavior.
LEAD by Example
Our state energy policy is rooted in one principle: a commitment to maximize the deployment of cost-effective investments in clean energy production and management, promoting Hawai‘i’s energy security.
