Reegle

Reegle 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 Reegle rather than just read about it. In short: reegle (lower-case) was a search engine specifically covering the fields of renewable energy, efficient energy use, and climate change issues. It was developed in 2005 by REEEP and REN21, with funding from several European government agencies.

Key takeaways

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

Reference excerpt

reegle (lower-case) was a search engine specifically covering the fields of renewable energy, efficient energy use, and climate change issues. It was developed in 2005 by REEEP and REN21, with funding from several European government agencies. At one point, it had 220,000 visitors per month. It was launched in July 2006. It was conceived as a public resource for governments, project developers, banks and finance institutions, NGOs, and international organisations as well as the general public. The central function of the site was a search engine, which offered a "mind map" based search refinement function. Users were able to click on a map of the world and get information on renewable energy and energy efficiency in that specific country, including relevant government ministries, private companies, country energy statistics, and a sampling of clean energy development projects in that specific area. The website offered an online glossary covering about 4,000 terms from the clean energy and climate sector, with definitions from Open Data sources. Translations of many terms into additional languages was also available. As of 2021, the portal is no longer active.

Worked examples

Example 1 — a first encounter with Reegle

Start with the simplest possible case. Write down what Reegle 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 Reegle 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 Reegle 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 Reegle

In research
Reegle 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 Reegle 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
Reegle is common in secondary-school and first-year university syllabi. It links to neighbouring topics Internet search engines, Organizations established in 2006, Renewable energy organizations, so understanding it makes those chapters shorter.
In everyday life
Look for Reegle 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.

Frequently asked questions

What is Reegle in simple terms?

reegle (lower-case) was a search engine specifically covering the fields of renewable energy, efficient energy use, and climate change issues. It was developed in 2005 by REEEP and REN21, with funding from several European government agencies.

Why does Reegle matter?

Because it connects several physics ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Reegle?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.

What does this page cover?

It gives you a compact reference excerpt plus original lgStudy explanations, examples, applications and study material on Reegle.
