Clean Energy Facts
Renewable energy sources resulted in 2,328 gigawatt-hours*, or 26.8 percent, of electric sales in 2017, 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 2017 total is an increase from 2,283 gigawatt hours or 25.8 percent of sales in 2016.
Tri-company electricity sales in 2017 totaled 8,690 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.
