What Hawaii power is made of

In plain words. Petroleum is the biggest source in Hawaii (75%), and the power made there is dirtier than the U.S. average per kWh. Plants with 34 MW are planned to retire by 2030. New plants with 75 MW are under construction.

In 2025 Hawaii plants of 1 MW or more made 9.3 TWh. The biggest sources: petroleum 74.8%, utility-scale solar 10.2%, wind 6.2%. For comparison, petroleum makes 0.4% of U.S. generation. Wind, solar and hydro together: 17.2% (22.6% for the U.S.). Hawaii plants only; imports and rooftop solar are not counted.
