Reference excerpt

Renewable energy in Tuvalu is a growing sector of the country's energy supply. 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 committed 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 million grant to the Government of Tuvalu to fund the production of electricity from renewable energy sources from 15% to 32% in Funafuti and from around 70% to over 90% in Tuvalu's outer islands. Funafuti will receive rooftop solar photovoltaic and battery energy storage systems and the outer islands of Nukufetau, Nukulaelae, and Nui will receive climate-resilient, ground-mounted solar photovoltaic systems. When the project is complete, 35% of electricity generation during daylight hours will be from renewable energy sources.

Tuvalu's carbon footprint Tuvalu's power has come from electricity generation facilities that use imported diesel brought in by ships. The Tuvalu Electricity Corporation (TEC) on the main island of Funafuti operates the large power station (2000 kW). Funafuti's power station comprises three 750 kVA diesel generators with 11 kV operating voltage, which were 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 PV 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 by photovoltaics began in 1979 but was mismanaged. A project installed hundreds of small household solar systems as well as solar powered medical refrigerators beginning in the early 1980s but poor training and management led to installation and maintenance problems. The ADB project funding announced in November 2019 will increase production of electricity from renewable energy sources from 15% to 32% in Funafuti and from around 70% to over 90% in Tuvalu's outer islands. The ABD funding will also strengthen the institutional capacity of Tuvalu Electricity Corporation (TEC) by training staff in renewable energy project development and implementation. Tuvalu, barely above sea level at any point, is concerned over global warming and sea level rise and sees its use of renewable energy as a moral example for others whose influence is greater. Kausea Natano, Tuvalu's minister for public utilities and industries in the Telavi Ministry stated this as "We thank those who are helping Tuvalu reduce its carbon footprint as it will strengthen our voice in upcoming international negotiations. And we look forward to the day when our nation offers an example to all -- powered entirely by natural resources such as the sun and the wind."

Tuvalu Energy Sector Development Project (ESDP) 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), which builds on the Tuvalu National Energy Policy, 2009. In November the funding to implement the MPREEE was boosted by a grant of US$6 million from the ADB, with the Government of Tuvalu contributing US$480,000 to the project.

Commitment under the Majuro Declaration 2013 The Sopoaga Ministry led by Enele Sopoaga made a commitment under the Majuro Declaration, which was signed on 5 September 2013, to implement power generation of 100% renewable energy (between 2013 and 2020). This commitment 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.

Commitment under the United Nations Framework Convention on Climate Change (UNFCCC) 1994 On 27 November 2015, the Government of Tuvalu announced its intended nationally determined contributions (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:

Worked examples

Example 1 — a first encounter with Renewable energy in Tuvalu

Start with the simplest possible case. Write down what Renewable energy in Tuvalu claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Renewable energy in Tuvalu before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Renewable energy in Tuvalu ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Renewable energy in Tuvalu

In research: Renewable energy in Tuvalu appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Renewable energy in Tuvalu in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Renewable energy in Tuvalu is common in secondary-school and first-year university syllabi. It links to neighbouring topics Energy in Tuvalu, Environment of Tuvalu, Renewable energy by country, so understanding it makes those chapters shorter.
In everyday life: Look for Renewable energy in Tuvalu outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
