Our Clean Energy Portfolio

Renewable energy sources resulted in 3,695 gigawatt-hours*, or 35.8 percent, of generation in 2024, as reported to the Hawaii Public Utilities Commission in our annual Renewable Energy Portfolio status report. This does not include energy savings from solar water heating or quantifiable energy efficiency. The 2024 total is an increase from 3,392 gigawatt-hours in 2023.

Hawaiian Electric generation in 2024 totaled 10,311 gigawatt-hours.

* A gigawatt-hour is a unit of electrical energy equal to one thousand megawatt hours, one million kilowatt-hours, or one billion watt-hours. A 100-watt bulb burning for one hour uses 100 watt-hours of electricity.
