- Three-fifths of Maine's households use fuel oil as their primary energy source for home heating, a larger share than any other state.
- In 2021, 72% of Maine's total electricity net generation came from renewable energy, and hydroelectric power provided the largest share at 27%.
- In 2021, Maine ranked fifth in the nation in the share of total in-state electricity generation provided by wind energy, and wind provided about 23% of Maine's in-state net generation.
- Forests cover about nine-tenths of Maine, a larger share than in any other state, and wood and wood waste-derived fuels supply most of the biomass Maine uses for electricity generation. In 2021, biomass supplied one-fifth of Maine’s total net generation, the second-largest share, after Vermont, among the states.
- In 2020, Maine’s natural gas use on a per capita basis was third-lowest in the nation, after Hawaii and Vermont, in large part because most of Maine lacks natural gas distribution systems.
