The pattern of energy production and use in Guam is shaped by its location, a remote island. Almost all energy is reliant on imports of petroleum products for use in transport and electricity. Guam has no domestic production of conventional fuels such as oil, natural gas or coal. Its economy is dependent on the import of gasoline and jet fuel for transport and residual fuel oil for electricity. One third of electricity produced is used in commercial settings including the leading industry of tourism. Despite making up about one-tenth of the islands population, the U.S. military uses one-fifth of the island's energy.[1]
Rising fuel costs and environmental concerns have led to major plans to alter the electrical industry in Guam. Renewables and cleaner burning natural gas and diesel power are planned.
