Renewable energy in Oceania

Renewable energy in Oceania is a earth science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Renewable energy in Oceania rather than just read about it. In short: This article summarises the status of renewable energy in Oceania. The Pacific island nations are heavily dependent on costly fossil fuel imports, so they are turning, to varying degrees, to renewable energy.

Key takeaways

Renewable energy in Oceania belongs to earth science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Renewable energy in Oceania to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Renewable energy in Oceania from memory before moving on to harder problems.

Reference excerpt

This article summarises the status of renewable energy in Oceania. The Pacific island nations are heavily dependent on costly fossil fuel imports, so they are turning, to varying degrees, to renewable energy. Options include household photovoltaic (PV) systems and hydroelectricity on the hillier islands.

Australia

New Zealand

Melanesia

Fiji The percentage of renewable electricity generation increased from 59% in 2013 to 65% in 2016. The Fiji Electricity Authority hopes to generate 81% renewably by 2020, from hydropower (c. 50% currently), biomass, solar energy and wind power.

Solomon Islands Renewable electricity generation grew from <1% in 2013 to 5% in 2016.

Vanuatu Renewable electricity generation grew from 16% in 2013 to 29% in 2016.

Micronesia Renewable electricity generation has risen from 0% in 2013 to 5% in 2016.

Federated States of Micronesia Over 350 household solar systems were installed on Yap's outer islands.

Kiribati Renewable electricity generation grew from 0.2% in 2013 to 10% in 2016.

Marshall Islands Renewable electricity generation accounts for <1% as of 2016.

Nauru Renewable electricity generation grew from <1% in 2013 to 3.2% in 2016.

Palau Renewable electricity generation grew from 0.4% in 2013 to 2.3% in 2016.

Polynesia

Cook Islands The percentage of renewable electricity generation grew from 3% in 2013 to 15% in 2016. Four PV-diesel hybrid systems are scheduled to be installed in the outer islands by mid-2017.

Niue Renewable electricity generation grew 2.5% in 2013 to 9% in 2016.

Samoa Between 2013 and 2016, renewable generation capacity grew from 7.5 MW to 15.4 MW, mostly due to solar energy systems, but also due to two wind turbines. Apolima became the first 100% renewable Pacific island.

Tokelau Almost 100% of renewable generation is due to solar PV systems.

Tonga In 2000, 75% of Tonga's energy came from petroleum imports, with biomass and photovoltaic systems accounting for the remainder. In April 2009, the government of Tonga sought to reduce this costly petroleum dependency by developing a plan, subsequently called the Tonga Energy Road Map 2010 – 2020 (TERM). Renewable electricity generation is expected to grow from 5.4% in 2013 to 13% in 2018.

Worked examples

Example 1 — a first encounter with Renewable energy in Oceania

Start with the simplest possible case. Write down what Renewable energy in Oceania claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In earth science, 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 Oceania 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 Oceania 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 Oceania

In research: Renewable energy in Oceania appears in earth science 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 Oceania 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 Oceania is common in secondary-school and first-year university syllabi. It links to neighbouring topics Oceania stubs, Renewable energy in Oceania, so understanding it makes those chapters shorter.
In everyday life: Look for Renewable energy in Oceania 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.
