Our Clean Energy Portfolio

Renewable energy sources resulted in 2,324 gigawatt-hours*, or 26.7 percent, of electricity sales in 2018, 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 2018 total is a slight decrease from 2,328 gigawatt-hours or 26.8 percent of sales in 2017, due to the disruption of Hawaii Island's geothermal generation by the Kilauea eruption.

Tri-company electricity sales in 2018 totaled 8,689 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.
