List of least carbon efficient power stations

List of least carbon efficient power stations is a 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 List of least carbon efficient power stations rather than just read about it. In short: This is a list of least carbon efficient power stations in selected countries. Lists were created by the WWF and lists the most polluting power stations in terms of the level of carbon dioxide produced per unit of electricity generated.

Key takeaways

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

Reference excerpt

This is a list of least carbon efficient power stations in selected countries. Lists were created by the WWF and lists the most polluting power stations in terms of the level of carbon dioxide produced per unit of electricity generated. In general lignite burning coal-fired power stations with subcritical boilers (in which bubbles form in contrast to the newer supercritical steam generator) emit the most. The Chinese national carbon trading scheme may follow the European Union Emission Trading Scheme in making such power stations uneconomic to run. However some companies such as NLC India Limited and Electricity Generation Company (Turkey) generate in countries without a carbon price. Lignite power stations built or retrofitted before 1995 often also emit local air pollution. In early 2021 the EU carbon price rose above 50 euros per tonne, causing many of the European plants listed below to become unprofitable, and close down. However, because many countries outside Europe and the USA do not publish plant level emissions data it was difficult to make up to date lists. Public information from space-based measurements of carbon dioxide by Climate Trace is expected to quantify CO2 from individual large plants before the 2021 United Nations Climate Change Conference, thus enabling large polluters to be identified.

2015 report - companies In 2015 the Stranded Assets Programme at the University of Oxford’s Smith School of Enterprise and the Environment published Stranded Assets and Subcritical Coal report analyzing inter alia carbon intensity of subcritical coal-fired power stations of 100 largest companies having these power stations.

2005 report - power station from 30 industrialised countries

2007 list - Europe

2018 - largest emitters The table lists the largest emitters, regardless of their carbon efficiency.

Other At over 1.34 tCO2-e/MWh Yallourn is the most carbon intense in Australia. In the very unlikely event of being built, the proposed Afşin-Elbistan C power station would become the least carbon efficient coal-fired power station.

Worked examples

Example 1 — a first encounter with List of least carbon efficient power stations

Start with the simplest possible case. Write down what List of least carbon efficient power stations claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In 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 List of least carbon efficient power stations 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 List of least carbon efficient power stations 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 List of least carbon efficient power stations

In research: List of least carbon efficient power stations appears in 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 List of least carbon efficient power stations 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: List of least carbon efficient power stations is common in secondary-school and first-year university syllabi. It links to neighbouring topics Economy-related lists of superlatives, Lists of coal-fired power stations, Lists of power stations, so understanding it makes those chapters shorter.
In everyday life: Look for List of least carbon efficient power stations 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.
