Our Clean Energy Portfolio

Renewable energy sources resulted in 3,174 gigawatt-hours*, or 38.4 percent, of electricity sales in 2021, 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 2021 total is an increase from 2,801 gigawatt-hours or 34.5 percent of sales in 2020.

Hawaiian Electric sales in 2021 totaled 8,261 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.
