American Samoa energy mix & electricity
Power plants in American Samoa produced 180 GWh of electricity in 2024. Oil provides 94.4% of it. Few countries depend so heavily on a single source.
The power system is very small (under 1 TWh a year), so it is not included in share-based world rankings. A single plant can change its mix dramatically from one year to the next.

American Samoa: electricity in context
Power plants in American Samoa produced 180 GWh of electricity in 2024. That puts it in the same league as British Virgin Islands. Oil provides 94.4% of it. Few countries depend so heavily on a single source.
5.6% of the country’s power came from renewable sources. That is 28 points below the world average of 33.8%. It is also below the average for Oceania (41.4%). Each kilowatt-hour emitted on average 611 g CO₂e, against a world average of 458 g. This is one of the more carbon-intensive grids in the world.
The net effect: renewables gained 5.6 percentage points of share since 2014. Total generation grew by 30 GWh over the same period. Carbon intensity dropped from 667 to 611 g/kWh, a 8% cut.
Coal has essentially never been burned for electricity here: its share has stayed below 1% throughout the record.
Solar (5.6%) and wind (0%) now add up to 5.6% of generation; the global figure is 17.3%. Per person, that is 214 kWh of solar electricity a year, versus a global average of 338 kWh. Solar first passed 1% of the mix in 2022.
Generation per person is 3,847 kWh a year, close to the world average of 3,860 kWh. American Samoa does not trade electricity with other countries: the grid is not interconnected with any neighbour.
