Energy consumption in GuamThe most important measure in the energy balance of Guam is the total consumption of
1.60 billion kWhof electric energy per year. Per capita this is an average of 9,486 kWh.
Guam can provide itself completely with self-produced energy. The total production of all electric energy producing facilities is 2 bn kWh, also 108% of own requirements. The rest of the self-produced energy is either exported into other countries or unused. Along with pure consumptions the production, imports and exports play an important role. Other energy sources such as natural gas or crude oil are also used.

Production capacities per energy sourceThe given production capacities for electric energy have a theoretical value, which could only be obtainable under ideal conditions. They are measuring the generatable amount of energy, that would be reached under permanent and full use of all capacities of all power plants. In practice this isn't possible, because e.g. solar collectors are less efficient unter clouds. Also wind- and water-power plants are not always operating under full load. All these values are only useful in relation to other energy sources or countries.

Usage of renewable energiesRenewable energies include wind, solar, biomass and geothermal energy sources. This means all energy sources that renew themselves within a short time or are permanently available. Energy from hydropower is only partly a renewable energy. This is certainly the case with river or tidal power plants. Otherwise, numerous dams or reservoirs also produce mixed forms, e.g. by pumping water into their reservoirs at night and recovering energy from them during the day when there is an increased demand for electricity. Since it is not possible to clearly determine the amount of generated energy, all energies from hydropower are displayed separately.
In 2018, renewable energies accounted for around 3.0 percent of actual total consumption in Guam. The following chart shows the percentage share from 1990 to 2018:
