Renewables.ninja

Renewables.ninja is a computer 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 Renewables.ninja rather than just read about it. In short: Renewables.ninja is a web tool developed by Imperial College London and ETH Zürich that shows the estimated amount of energy that could be generated by wind or solar farms at any location. The model has been tested by Iain Staffell who is the co‑developer of renewables.ninja, from the Centre for Environmental Policy at Imperial College London, and Stefan Pfenninger from ETH Zürich to estimate the productivity of all…

Key takeaways

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

Reference excerpt

Renewables.ninja  is a web tool developed by Imperial College London and ETH Zürich that shows the estimated amount of energy that could be generated by wind or solar farms at any location. The model has been tested by Iain Staffell who is the co‑developer of renewables.ninja, from the Centre for Environmental Policy at Imperial College London, and Stefan Pfenninger from ETH Zürich to estimate the productivity of all wind farms planned or under construction in Europe for the next 20 years. German electrical supplier RWE are using it to test their own models of output.

Worked examples

Example 1 — a first encounter with Renewables.ninja

Start with the simplest possible case. Write down what Renewables.ninja claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer 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 Renewables.ninja 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 Renewables.ninja 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 Renewables.ninja

In research: Renewables.ninja appears in computer 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 Renewables.ninja 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: Renewables.ninja is common in secondary-school and first-year university syllabi. It links to neighbouring topics Sustainable energy, Web software, Web software stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Renewables.ninja 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.
