Tuvalu’s energy mix is heavily reliant on imported petroleum, which accounted for approximately 96% of the country’s total energy supply in 2021, with solar and other renewable energy sources providing the remaining 4%. While diesel generators currently dominate, the country is actively working to transition to 100% renewable energy, with significant solar PV initiatives, particularly on outer islands.

Tuvalu is exploring green hydrogen as a key strategic pathway to achieve 100% renewable energy, aiming to eliminate fossil fuel dependency and enhance energy security. As a low-lying nation facing existential climate threats, this initiative aligns with its 2025 goals for total renewable energy and long-term adaptation.
