Tetsunari Iida

Tetsunari Iida 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 Tetsunari Iida rather than just read about it. In short: Tetsunari Iida (飯田哲也, Iida Tetsunari; born 1959, Yamaguchi Prefecture, Japan) is director of the Institute for Sustainable Energy Policies in Japan. Following the Fukushima nuclear disaster, he is calling for a decrease in Japan's reliance on nuclear power and an increase in renewable energy use.

Key takeaways

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

Reference excerpt

Tetsunari Iida (飯田哲也, Iida Tetsunari; born 1959, Yamaguchi Prefecture, Japan) is director of the Institute for Sustainable Energy Policies in Japan. Following the Fukushima nuclear disaster, he is calling for a decrease in Japan's reliance on nuclear power and an increase in renewable energy use. Iida started his career as a nuclear engineer, but he quit in 1992, and went to study renewable energy in Sweden. In September 2011, Iida launched the Japan Renewable Energy Foundation, which is backed by ¥1 billion (US$13 million) from Japan's richest man, Masayoshi Son. Solar power in Japan has been expanding since the late 1990s. The country is a leading manufacturer of photovoltaics (PV) and a large installer of domestic PV systems with most of them grid connected.

Biography Iida started his career as a nuclear engineer, but he quit in 1992, and went to study renewable energy in Sweden. When he returned to Japan in 1998, he formed the Institute for Sustainable Energy Policies. Since then he has set up several green mutual funds. In September 2011, Iida launched the Japan Renewable Energy Foundation, which is backed by ¥1 billion (US$13 million) from Japan's richest man, Masayoshi Son. The foundation will bring together some 100 experts from around the world to analyse obstacles to implementing renewable energy, and offer policy recommendations to the new Japanese government.

Worked examples

Example 1 — a first encounter with Tetsunari Iida

Start with the simplest possible case. Write down what Tetsunari Iida 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 Tetsunari Iida 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 Tetsunari Iida 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 Tetsunari Iida

In research: Tetsunari Iida 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 Tetsunari Iida 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: Tetsunari Iida is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1959 births, Activists from Yamaguchi Prefecture, Energy engineers, so understanding it makes those chapters shorter.
In everyday life: Look for Tetsunari Iida 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.
