Energy and resources vocabulary: the words that lift a frequent topic.
Energy, resources and the shift to renewables run through Task 2 and Part 3, from fossil fuels to energy security. The ideas are familiar; the marks are in precise, topic-specific language. Swap the everyday word for the right collocation and the same point reads a band higher.
Why this matters. Lexical Resource is a quarter of your mark, and on a familiar topic the examiner has read the plain version a thousand times. The lift is not rarer words; it is accurate collocation used naturally. A common phrase used correctly beats a showy word used wrongly, every time.
Four clusters that cover most Energy questions.
You do not need a glossary. You need a handful of accurate collocations in each of these areas, ready to deploy.
Energy sources
fossil fuels · renewable energy · solar and wind power · nuclear power
Where energy comes from, the base lexis.
Renewable energy now rivals fossil fuels on cost.
Consumption & demand
energy consumption · energy efficiency · the power grid · rising demand
How energy is used, a common Task 2 line.
Energy efficiency cuts both bills and emissions.
Resources & scarcity
natural resources · finite resources · resource depletion · sustainable use
The limits of supply, where Task 2 lands.
Finite resources cannot meet unlimited demand.
Transition & policy
the energy transition · reduce reliance on · carbon emissions · energy security
How systems change, where Part 3 reaches.
The energy transition reduces reliance on imports.
Name the source or the metric
The weak answer says “we use too much energy”. The lift is precise: fossil fuels, renewable energy, energy efficiency, finite resources. One accurate term signals control.
The same point, from Band 6 to Band 8.
At Band 5
Energy is discussed with very general words (power, oil, use up, run out), with vague verbs (we use too much). Precise terms (renewable, efficiency) are missing.
At Band 6
“We use a lot of oil and gas, which will run out, so we should use more solar and wind power instead.” The idea is fine, but general.
At Band 7
“Shifting from fossil fuels to renewable energy improves energy security and cuts carbon emissions.” Topic collocations (fossil fuels, renewable energy, carbon emissions) carry real information.
At Band 8+
“While renewable energy reduces reliance on finite fossil fuels, the transition demands heavy investment in the power grid and storage.” Precise lexis, abstraction, and a controlled complex sentence.
The upgrade most worth making.
Each swap takes a vague, everyday phrase and replaces it with the collocation an examiner expects on this topic. Use them where they fit naturally, not all at once.
| Instead of… | Use… | For example |
|---|---|---|
| oil, gas and coal | fossil fuels | Fossil fuels still dominate supply. |
| clean energy | renewable energy | Renewable energy is expanding fast. |
| using less energy | energy efficiency | Insulation improves energy efficiency. |
| energy running out | resource depletion | Resource depletion is accelerating. |
| resources that will run out | finite resources | Oil is a finite resource. |
| using resources carefully | sustainable use | Sustainable use protects supply. |
| not relying on imports | energy security | Renewables strengthen energy security. |
| carbon from energy | carbon emissions | Coal produces high carbon emissions. |
Two cautions. Distinguish the source (fossil fuels, renewables) from the metric (efficiency, consumption). And weigh the cost of transition rather than treating renewables as cost-free. For the general method, see vocabulary & cohesion →
Say it another way.
The Lexical Resource descriptors reward paraphrase, and an answer that echoes the question’s own words proves nothing about your range. Each row takes a phrase the question will hand you and shows the version worth writing instead.
| The question says… | You can write… | For example |
|---|---|---|
| energy from the sun and wind | renewable energy / renewables | Renewable energy is now cheaper than the fuels it replaces. |
| oil, coal and gas | fossil fuels | Every economy still leans on fossil fuels more than it admits. |
| using less energy | improving energy efficiency | Improving energy efficiency is the cheapest power station never built. |
| the oil will run out | fossil fuels are finite / resource depletion | Finite resources make the transition a question of when, not whether. |
| gases that warm the planet | carbon emissions | Cutting carbon emissions costs less than living with the alternative. |
One caution. Paraphrase the idea once, early, and then move on. Recycling every synonym you know reads as display, not control, and control is what the band descriptors actually reward.

Recognising the right word above is the easy half. Now type the word each sentence needs. The first letter is given, and every answer appears somewhere on this page. Nothing is sent anywhere.
Then use it where it counts. Now take it into the exam. Any topic on this page can surface in Part 3 or as an essay in the question bank, and the word upgrader will ladder the plain words you still fall back on.
You can collect topic words. Using the right one, accurately, under timed pressure is the work.
Memorised “big” words used wrongly cost marks; precise collocations used naturally earn them, and the difference is hard to judge in your own writing.
In a lesson I mark your topic vocabulary the way an examiner does, where a collocation is exactly right, where it is forced, and where a plain word would have been stronger. Lessons are £20 for fifty minutes, one to one, in proper British English; the first lesson doubles as a full assessment. This page is drawn from the vocabulary work in The Proper English Grammar Guide to IELTS Speaking.
