Profile Overview

Quick Facts

  • More than two-fifths of New Hampshire households use fuel oil as their primary heating fuel, the second-largest share among the states and about 10 times greater than the national average.
  • Seabrook, one of only two nuclear power plants in New England and the largest power plant in New Hampshire, provided 56% of New Hampshire’s 2021 total in-state electricity net generation.
  • In 2021, 16% of New Hampshire's electricity generation came from renewable resources, including small-scale solar installations. Most of the state's renewable generation comes from hydroelectric power, biomass, and wind.
  • New Hampshire has the two remaining coal-fired power plants in New England—Schiller at Portsmouth and Merrimack at Bow. Coal-fired plants no longer supply baseload power, but they play an important role in providing electricity on high demand days.
  • New Hampshire is one of only eight states and the District of Columbia where the residential sector is the largest energy consumer, even though about 1 in 9 New Hampshire homes are only seasonally or occasionally occupied.
