Our Clean Energy Portfolio
Renewable energy sources resulted in 3,392 gigawatt-hours*, or 33.3 percent, of generation in 2023, 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 2023 total is an increase from 3,269 gigawatt-hours in 2022.
Hawaiian Electric generation in 2023 totaled 10,189 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.
