Tuvalu has committed to sourcing 100% of its electricity from renewable energy. This is considered possible because of the small size of the population of Tuvalu and its abundant solar energy resources due to its tropical location. It is somewhat complicated because Tuvalu consists of nine inhabited islands. The Tuvalu National Energy Policy (TNEP) was formulated in 2009, and the Energy Strategic Action Plan defines and directs current and future energy developments so that Tuvalu can achieve the ambitious target of 100% renewable energy for power generation by 2020.The program is expected to cost 20 million US dollars and is supported by the e8, a group of 10 electric companies from G8 countries.The Government of Tuvalu worked with the e8 group to develop the Tuvalu Solar Power Project, which is a 40 kW grid-connected solar system that is intended to provide about 5% of Funafuti’s peak demand, and 3% of the Tuvalu Electricity Corporation's annual household consumption. Tuvalu participates in the Alliance of Small Island States (AOSIS), which is a coalition of small island and low-lying coastal countries that have concerns about their vulnerability to the adverse effects of climate change. Under the Majuro Declaration, which was signed on 5 September 2013, Tuvalu has commitment to implement power generation of 100% renewable energy (between 2013 and 2020), which is proposed to be implemented using Solar PV (95% of demand) and biodiesel (5% of demand). The feasibility of wind power generation will be considered.In November 2015 Tuvalu committed to reduction of emissions of greenhouse gases from the electricity generation (power) sector to almost zero emissions by 2025. In November 2019, the Asian Development Bank (ADB) approved a US$6.

The Tuvalu Electricity Corporation (TEC) on the main island of operates the large power station (2000 kW).Funafuti's power station comprises three 750 kVA diesel generators with 11 kV operating voltage, which was installed in 2007. Total power output is 1,800 kW. The old generators have remained offline (1920 kW) but are available as back-up to the main system. The cost of diesel is subsidised by approximately 40% of the annual fuel consumption through the Japan Non Project Grant Assistance (NPGA), although this subsidy may end, which will expose the true cost of diesel generation of electricity.The installed capacity in Funafuti in 2020 was 735 kW compared to 1800 kW of diesel (16% penetration).Seven of the eight outer islands are powered by 48 - 80 kW each diesel generators with a total generating capacity per island averaging 176 kW, although Vaitupu generates 208 kW and Nukulaelae generates 144 kW. Niulakita operates individual DC home solar systems. In the other islands the diesel generators have been run for 12–18 hours per day.For the small power stations on the outlying islands, fuel has to be transferred to 200 litres (44 imp gal; 53 US gal) barrels and offloaded from the ships. A small project to power the inter-island telecommunications systems.
In 2014 the Tuvalu Electricity Corporation (TEC) began implementing a Master Plan for Renewable Energy and Energy Efficiency (MPREEE) through the Tuvalu Energy Sector Development Project (ESDP), whichbuilds on the Tuvalu National Energy Policy, 2009.In November the funding to implement the MPREEE was boosted by a grant of US$6 milli.

On 27 November 2015 the Government of Tuvalu announced its (NDCs) in relation to the reduction of greenhouse gases (GHGs) under provisions of the United Nations Framework Convention on Climate Change (UNFCCC), which became effective on 21 March 1994: On 27 November 2015 the Government of Tuvalu announced its (NDCs) in relation to the reduction of greenhouse gases (GHGs) under provisions of the United Nations Framework Convention on Climate Change (UNFCCC), which became effective on 21 March 1994: Tuvalu commits to reduction of emissions of green-house gases from the electricity generation (power) sector, by 100%, ie almost zero emissions by 2025. Tuvalu’s indicative quantified economy-wide target for a reduction in total emissions of GHGs from the entire energy sector to 60% below 2010 levels by 2025. These emissions will be further reduced from the other key sectors, agriculture and waste, conditional upon the necessary technology and finance. These targets go beyond the targets enunciated in Tuvalu’s National Energy Policy (NEP) and the Majuro Declaration on Climate Leadership (2013). Currently, 50% of electricity is derived from renewables, mainly solar, and this figure will rise to 75% by 2020 and 100% by 2025. This would mean almost zero use of fossil fuel for power generation. This is also in line with our ambition to keep the warming to less than 1.5°C, if there is a chance to save atoll nations like Tuvalu.
In 2007, Tuvalu was getting 2% of its energy from solar,through 400 small systems managed by the Tuvalu Solar Electric Co-operative Society. These were installed beginning in 1984 and, in the late 1990s, 34% of families in the outer islands had a PV system (which generally powered 1-3 lights and perhaps a few hours a day of radio use).Each of the eight islands had a med. In 2007, Tuvalu was getting 2% of its energy from solar,through 400 small systems managed by the Tuvalu Solar Electric Co-operative Society. These were installed beginning in 1984 and, in the late 1990s, 34% of families in the outer islands had a PV system (which generally powered 1-3 lights and perhaps a few hours a day of radio use).Each of the eight islands had a medical center with a PV-powered vaccine refrigerator and each island's solar technician had a larger PV system which ran a household refrigerator.Followup on the installations showed no deterioration of the PV panels but switches and light fixtures had suffered damage or failed from the salt air. The implementation of the Tuvalu Solar Power Project in 2008–9, involved the installation of a 40 kW grid-connected solar system that is intended to provide about 5% of ’s peak demand, and 3% of TEC's annual household consumption.The first large scale system in Tuvalu was a 40 kWinstallation on the roof of . This grid-connected 40 kW solar system was established in 2008 by the E8 and Japan Government through Kansai Electric Company (Japan) and contributes 1% of electricity production on Funafuti.Future plans include expanding this plant to 60 kW. A 46 kW solar installation with battery storage at the .
is also mentioned as a future electricity source. Tuvalu's commitment, as part of the , is to implement power generation of 100% renewable energy (between 2013 and 2020). The feasibility of wind power generation will be considered as part of this commitment.

6 FAQs about [Water energy storage Tuvalu]
Why should Tuvalu invest in wind energy?
Development of wind energy offers another opportunity to Tuvalu: to tackle the important issue of water supply. When the supply of electricity exceeds the demand, the additional capacity can be used for water desalinization or water purification.
How can Tuvalu protect its energy supply?
Protect Tuvalu’s energy supply from the whims of the international market. Using specific bioenergy technologies such as biogas digestion can help reduce pollution, run-off and contamination from organic waste, including human and animal sewage, therefore preventing land, sea, and groundwater contamination.
How much energy is wasted in Tuvalu?
Only 3,232 toe (71%) of primary energy supply reached an end-use category. 1,341 toe (29% of primary energy supply) was wasted, mainly due to low electricity generation efficiency. Tuvalu’s electricity consumption is increasing rapidly at a 3.8% yearly average rate over the last ten years. It reached 4,121 MWh in 2004.
What is the main source of energy in Tuvalu?
The primary energy consumption represents the upstream supply. The only national energy source is biomass (18% of total consumption). Photovoltaic and thermal solar contribute for less than 1%. The balance of supply is oil (Fig. 2). Tuvalu is close to being a totally oil dependent economy.
How does solar thermal work in Tuvalu?
Solar thermal consists of using solar radiation directly to heat e.g. boiling water, cooking food. In Tuvalu, the only actual working application is to produce sanitary hot water for washing is in the new hospital. The 2 m2 solar collector installation with a tank storing 300 litres of water is working well.
Should energy data be consolidated in Tuvalu?
One of the study’s recommendations is the consolidation of all energy data, to build an energy balance and to include it in the annual economy report. Since Tuvalu’s electricity generation efficiency is low, around 35%, the significance of the electricity sector is higher in the primary energy balance than in final end-use consumption.
