Solomon Islands energy mix & electricity
Electricity generation in the Solomon Islands reached 110 GWh in 2024. Oil provides 90.9% 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.

Solomon Islands: electricity in context
Electricity generation in the Solomon Islands reached 110 GWh in 2024. Oil provides 90.9% of it. Few countries depend so heavily on a single source.
Renewables supplied 9.1% of the electricity. That is 25 points below the world average of 33.8%. It is also below the average for Oceania (41.4%). Each kilowatt-hour emitted on average 636 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 9.1 percentage points of share since 2014. Total generation grew by 20 GWh over the same period. Carbon intensity dropped from 667 to 636 g/kWh, a 5% cut.
Coal has essentially never been burned for electricity here: its share has stayed below 1% throughout the record.
Solar (9.1%) and wind (0%) now add up to 9.1% of generation; the global figure is 17.3%. Solar first passed 1% of the mix in 2022.
Generation per person is 134 kWh a year, 3% of the world average of 3,860 kWh. The Solomon Islands does not trade electricity with other countries: the grid is not interconnected with any neighbour.
