Profile Overview

Quick Facts

  • Guam has no fossil energy resources and meets nearly all of its energy needs with imported petroleum products. In 2019, about 31% of the petroleum consumed in Guam was motor gasoline, 28% was jet fuel, 24% was diesel fuel, 15% was residual fuel, and propane accounted for 2% of petroleum use.
  • Guam’s electricity costs, including fuel surcharges to cover petroleum costs, are usually two to three times higher than the average electricity rate for the 50 U.S. states, although Guam’s power prices are typically the lowest among the nearby Pacific islands.
  • The commercial sector, including hotels, restaurants, and commercial buildings, consumes more than one-third of Guam's electricity. The U.S. military accounts for one-fifth of the Guam's electricity consumption.
  • About 120 megawatts of new solar power generating capacity is expected to come online in Guam in 2022, offsetting some of the lost generating capacity at the Cabras power plant.
  • In 2019, Guam’s legislature updated the island's renewable portfolio standard to require that 50% of electricity sales come from renewables by 2035 and 100% by 2045.
