State Profile and Energy Estimates

Changes to the State Energy Data System (SEDS) Notice: In October 2023, we updated the way we calculate primary energy consumption of electricity generation from noncombustible renewable energy sources (solar, wind, hydroelectric, and geothermal). Visit our Changes to 1960—2022 conversion factor for renewable energy page to learn more.

Profile Overview

Quick Facts

  • In 2022, 7 out of every 10 Maine households used petroleum products for home heating, a larger share than in any other state.
  • In 2022, renewable resources fueled 64% of Maine's total electricity net generation, and wind provided the largest share at 23% of the state's total net generation.
  • Maine uses less energy than 44 states, but Maine's economy uses significantly more energy per dollar of GDP than the national average.
  • Forests cover about nine-tenths of Maine, the largest share of any state, and forest products are both a major energy-intensive industry and an important biomass resource. In 2022, biomass, mostly wood and wood-derived fuels, supplied 14% of Maine’s total electricity net generation, the second-largest share, after Vermont, among the states.
  • In 2021, 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.
