International Renewable Energy Alliance

International Renewable Energy Alliance is a physics 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 International Renewable Energy Alliance rather than just read about it. In short: International Renewable Energy Alliance (REN Alliance) is a formal partnership entered into on 4 June 2004 by five non-profit international renewable energy organisations: International Hydropower Association (IHA), International Solar Energy Society (ISES), International Geothermal Association (IGA), World Wind Energy Association (WWEA), World Bioenergy Association (WBA). (Since June 2009) They represent the hydro…

Key takeaways

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

Reference excerpt

International Renewable Energy Alliance (REN Alliance) is a formal partnership entered into on 4 June 2004 by five non-profit international renewable energy organisations:

International Hydropower Association (IHA), International Solar Energy Society (ISES), International Geothermal Association (IGA), World Wind Energy Association (WWEA), World Bioenergy Association (WBA). (Since June 2009) They represent the hydro, geothermal, solar, and wind power/energy and bioenergy sector. The alliance provides a unified cross-sectoral voice on renewable energy in international and regional energy fora and media. Climate change concerns, coupled with high oil prices, peak oil, and increasing government support, are driving increasing renewable energy legislation, incentives and commercialization. As of 2011, 119 countries have some form of national renewable energy policy target or renewable support policy. National targets now exist in at least 98 countries. There is also a wide range of policies at state/provincial and local levels. As of December 2019, the honorary chairman of the REN Alliance is former Australian senator Peter Rae, who was previously also chairman of Hydro Tasmania.

Worked examples

Example 1 — a first encounter with International Renewable Energy Alliance

Start with the simplest possible case. Write down what International Renewable Energy Alliance 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 International Renewable Energy Alliance 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 International Renewable Energy Alliance 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 International Renewable Energy Alliance

In research: International Renewable Energy Alliance 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 International Renewable Energy Alliance 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: International Renewable Energy Alliance is common in secondary-school and first-year university syllabi. It links to neighbouring topics International renewable energy organizations, so understanding it makes those chapters shorter.
In everyday life: Look for International Renewable Energy Alliance 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.
