Who this is for: Cambridge IGCSE Coordinated Science (0654) students who want energy resources — renewable and non-renewable sources, advantages and disadvantages — to become a reliable source of marks in evaluation questions.
What query it owns: how to understand and revise energy resources in Cambridge IGCSE Coordinated Science.
Why this is safe: this page owns the energy resources revision-guide angle, while Tutopiya’s Energy Resources subtopic page owns the learning resource and the free Energy Resources quiz owns the practice.

Energy resources are the sources from which we obtain useful energy — fossil fuels, nuclear, solar, wind, hydro and more. Cambridge IGCSE Coordinated Science (0654) expects you to classify resources as renewable or non-renewable, compare advantages and disadvantages, and evaluate environmental impact. This guide maps each source to the describe, compare and evaluate questions examiners set.

Key takeaways

• Non-renewable: coal, oil, natural gas, nuclear — finite supply.
• Renewable: solar, wind, hydro, tidal, geothermal, biofuels — replenished naturally.
• Fossil fuels release CO₂ and contribute to climate change.
• Renewables are cleaner but often intermittent or location-dependent.
• Evaluation questions reward balanced advantages and disadvantages.

What are energy resources in Cambridge IGCSE Coordinated Science?

Energy resources supply the energy transferred in power stations, transport and homes. Non-renewable resources took millions of years to form and will run out. Renewable resources are naturally replenished on a human timescale. Examiners test whether you can name examples, explain how each generates electricity, and weigh up pros and cons — not just list facts.

Study the full comparison tables on Tutopiya’s Energy Resources subtopic page before tackling evaluation questions.

Renewable vs non-renewable energy resources

Type	Examples	Key advantage	Key disadvantage
Fossil fuels	Coal, oil, natural gas	Reliable, high energy density	CO₂ emissions, finite, pollution
Nuclear	Uranium/plutonium fission	No CO₂ in operation, high output	Radioactive waste, high setup cost
Solar	Solar panels	Renewable, no running fuel cost	Intermittent, needs sunlight
Wind	Wind turbines	Renewable, no fuel cost	Intermittent, visual/noise impact
Hydroelectric	Dams	Reliable, fast response	Habitat disruption, site-specific
Biofuels	Ethanol, biogas	Renewable, carbon-neutral potential	Land use, competes with food crops

How electricity is generated from different resources

Resource	Energy transfer chain
Fossil fuel power station	Chemical (fuel) → thermal → kinetic (turbine) → electrical
Nuclear	Nuclear → thermal → kinetic → electrical
Hydroelectric	GPE (water) → kinetic → electrical
Wind	Kinetic (wind) → electrical
Solar	Radiation (light) → electrical

Energy resources in past-paper wording: command words that matter

Command word / phrase	What the question wants	Typical energy resources stem
State	Name a resource or type	”State two renewable energy resources.”
Describe	How energy is obtained	”Describe how a hydroelectric power station generates electricity.”
Compare	Similarities and differences	”Compare wind power and fossil fuel power.”
Evaluate	Balanced judgement	”Evaluate the use of nuclear power as an energy resource.”

Worked exam-style stems (how to answer the wording)

1. “State two advantages and two disadvantages of using wind turbines.” Advantages: renewable; no CO₂ during operation. Disadvantages: intermittent (no wind = no power); visual/noise impact on local area. Reward: one point per advantage/disadvantage with brief explanation.
2. “Describe the energy transfers in a coal-fired power station.” Chemical energy (coal) → thermal energy (burning) → kinetic energy (steam/turbine) → electrical energy (generator). Reward: correct store sequence.
3. “Explain why fossil fuels are described as non-renewable.” They take millions of years to form from dead organisms; the rate of use exceeds the rate of formation, so supplies are finite. Reward: finite + slow formation.

Test yourself with the Energy Resources quiz once you can classify resources and evaluate advantages and disadvantages.

How energy resources connect to the rest of Coordinated Science

Energy resources apply Energy transfers to real-world generation and link to Power (output ratings). Chemistry connections include Fuels and Carbon Dioxide And Methane. The Cambridge IGCSE Coordinated Science resource hub links every Work, Energy And Power subtopic.

Common mistakes students make

• Calling nuclear renewable (it uses finite uranium — it is non-renewable).
• Listing only advantages in evaluate questions without disadvantages.
• Confusing biofuels with being completely pollution-free (combustion still produces CO₂).
• Saying renewables are always reliable (solar and wind are intermittent).
• Forgetting the energy transfer chain in power station description questions.

Frequently asked questions

What is a renewable energy resource? A resource naturally replenished on a human timescale, such as solar, wind or hydroelectric power.

Is nuclear power renewable? No — uranium fuel is finite, so nuclear is classified as non-renewable in Cambridge IGCSE Coordinated Science.

What are the main disadvantages of fossil fuels? Finite supply, CO₂ and greenhouse gas emissions, air pollution, and contribution to climate change.

How do I revise energy resources effectively? Learn the classification table, practise describe and evaluate stems, then take the Energy Resources quiz.
