Our Clean Energy Portfolio

Renewable energy sources resulted in 2,801 gigawatt-hours*, or 34.5 percent, of electricity sales in 2020, 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 2020 total is an increase from 2,480 gigawatt-hours or 28.4 percent of sales in 2019.

Hawaiian Electric sales in 2020 totaled 8,120 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.
