Profile Overview

Quick Facts

  • In 2020, the residential sector and commercial sector each accounted for about one-third of Guam's electricity use, while the U.S. military accounted for one-fifth and the Guam government made up one-tenth.
  • Guam has no fossil energy resources and meets nearly all of its energy needs with imported petroleum products. Guam's energy consumption on a per capita basis is about half the U.S. average.
  •  In 2020, about 33% of the petroleum sales in Guam were for residual fuel, 24% were motor gasoline, 24% were jet fuel, 17% were diesel fuel, and propane accounted for 2%.
  • Guam’s electricity costs, including fuel surcharges to cover petroleum costs, are twice as high as the U.S. average residential electricity rate, although Guam’s power prices are typically the lowest among the nearby Pacific islands.
  • Guam's renewable portfolio standard was updated in 2019 to require that 50% of the island's electricity sales come from renewables by 2035 and 100% by 2045. About 120 megawatts of solar power generating capacity from two new solar farms is expected to come online in Guam in 2022.
