Petroleum accounts for 100 per cent of Tuvalu’s energy supply (Figure 9.1) and 10 per cent of GDP (SPC 2016). Petroleum replaced biomass as its major energy source in the 1990s. Fuel is imported into Tuvalu via Fiji by Pacific Energy, which owns all storage and distribution facilities. This fuel is mainly used for electricity generation (41%) and transport (40%) (Figure 9.3).
