Duration: 50 minutes
Starter Activity (5 minutes)
Review Previous Lesson
Quick recap: write 3 key points from Lesson 1 on p3 national and global energy. Check them against the notes below.
Main Content (35 minutes)
Non-renewable energy resource: A resource that will run out one day because it is being used up faster than it can be replaced. Examples: fossil fuels and nuclear fuel.
Renewable energy resource: A resource that will never run out (or can be replaced within a human lifetime). Examples: solar, wind, hydroelectric, tidal, geothermal, biomass, wave.
Fossil fuels: Coal, oil and natural gas — formed from the remains of ancient organisms over millions of years. They are non-renewable and produce carbon dioxide when burned.
Current UK energy mix: The UK generates most of its electricity from natural gas, with a growing proportion from renewables (especially wind and solar). Coal use has dropped significantly. Nuclear provides a steady base load.
Fossil fuels remain dominant because: they are reliable (available on demand), the infrastructure already exists (power stations, gas pipelines, petrol stations), and they are relatively cheap to set up compared to some renewable alternatives.
We need to transition to renewables because: fossil fuels are finite and will run out, burning fossil fuels releases CO₂ which causes climate change, and pollution from fossil fuels harms health and the environment.
| Term | Meaning | Example |
|---|---|---|
| Coal | Burned to heat water → steam → turbine → generator | Abundant, reliable, relatively cheap |
| Oil | Burned in power stations or used as petrol/diesel | High energy density, reliable, transport fuel |
| Natural gas | Burned to heat water → steam → turbine → generator | Cleaner than coal, flexible supply, quick to start |
| Nuclear | Uranium fission releases heat → steam → turbine → generator | Very high energy output, no CO₂, reliable |
| Solar | Solar cells convert light directly to electricity; solar panels heat water | No CO₂, free energy source, can be used in remote areas |
| Wind | Wind turns turbine blades → generator | No CO₂, free energy source, quick to build |
| Hydroelectric | Water stored behind dam, released to turn turbines | Reliable, can start quickly, high output |
| Tidal | Rising/falling tides turn turbines in a barrage | Predictable, reliable, no CO₂ |

Lesson 3: Application: p3 national and global energy
Duration: 50 minutes
Starter Activity (5 minutes)
Quick Recall
Recall the key terms: Non-renewable energy resource, Renewable energy resource, Fossil fuels. Define each in one sentence.
Main Content (35 minutes)
Parent/Teacher Guide: Let your student attempt each question alone first, then compare with the model answer. Award method marks for correct working even if the final answer is wrong.
Q1: Foundation Define the terms "renewable energy resource" and "non-renewable energy resource". Give two examples of each.
Answer: A renewable energy resource is one that will never run out (or can be replaced within a human lifetime). Examples: solar, wind. A non-renewable resource is one that will run out because it is being used faster than it can be replaced. Examples: coal, natural gas.
Q2: Foundation Give two reasons why the UK still uses fossil fuels for electricity generation.
Answer: 1) Fossil fuels are reliable — they can produce electricity on demand, unlike some renewables. 2) The infrastructure already exists (power stations, gas pipelines) so it is cheaper to continue using them than to build new renewable infrastructure.
Q3: Foundation Explain why tidal energy is more reliable than wind energy.
Answer: Tidal energy is more reliable because tides are predictable and happen twice daily regardless of weather. Wind energy depends on weather conditions — if there is no wind, no electricity is generated.
Q4: Higher A country currently generates 60% of its electricity from coal. It aims to reduce this to 10% in 20 years. Suggest which renewable sources it could use instead and discuss the challenges it would face.
Answer: The country could use wind and solar (both quick to build, no CO₂), hydroelectric (reliable backup), and possibly nuclear (reliable, no CO₂, but expensive and slow to build). Challenges: (1) renewables are intermittent, so need energy storage or backup; (2) building new infrastructure is expensive; (3) some renewables need specific geography (hydro needs rivers/hills); (4) nuclear takes many years to build and produces radioactive waste.
Q5: Higher Explain why nuclear power is classified as non-renewable even though it does not produce CO₂ during operation.
Answer: Nuclear power is non-renewable because it uses uranium fuel, which is a finite resource that will eventually run out. It cannot be replaced within a human lifetime. Even though it does not produce CO₂, the fuel supply is limited, which is the definition of non-renewable.
Q6: Higher Compare the environmental impact of hydroelectric power and wind power. Include both positive and negative effects.
Answer: Hydroelectric positive: no CO₂ emissions, reliable. Negative: building dams floods valleys, destroys habitats, displaces communities. Wind power positive: no CO₂, minimal land impact (land can still be farmed). Negative: visual pollution, noise, can kill birds and bats, unreliable without wind. Both are renewable and do not produce CO₂ during operation.

Extended Answer
Extended question: Extended Answer 6 marks: Evaluate whether the UK should switch entirely to renewable energy sources for electricity generation. Include arguments for and against, and give a justified conclusion. <div class="
Arguments for switching entirely to renewables: (1) Fossil fuels are finite and will eventually run out, so we must transition to sustainable sources. (2) Burning fossil fuels releases CO₂, which is the main cause of climate change — renewables produce no CO₂ during operation. (3) Using renewables improves energy security by reducing dependence on imported fossil fuels, making the UK less vulnerable to supply disruptions and price changes. (4) Renewable technology is improving and costs are falling. Arguments against switching entirely: (1) Wind and solar are intermittent — they cannot generate electricity when there is no wind or sunlight, so backup power or large-scale energy storage is needed. (2) Building new renewable infrastructure is very expensive and takes time. (3) Some renewables cause environmental damage — hydroelectric dams flood valleys and destroy habitats. (4) Nuclear power provides reliable, low-carbon base-load electricity and may still be needed. Conclusion: The UK should aim to generate most electricity from renewables but a complete switch is currently impractical due to reliability concerns. A mix of renewables with some nuclear or gas backup, plus improved e
Exam Tips: When comparing energy sources, always give both advantages AND disadvantages — exam questions often ask you to evaluate or discuss. | Use the correct terms: reliable means it can provide energy on demand; renewable means it will not run out. | If asked "why do we still use fossil fuels?", the key points are: reliability, existing infrastructure, cost . | If asked "why switch to renewables?", the key points are: finite resources, climate change, pollution . | Biomass is carbon neutral — be prepared to explain this using photosynthesis and the carbon cycle. | Always consider the full picture — not just whether a source is renewable, but also reliability, cost, and environmental impact.
Common Errors: Watch Out! 1. Wrong: Nuclear power is a renewable energy source Correct: Nuclear power is non-renewable — it uses uranium fuel which is finite and will run out, even though it does not produce CO₂ during operation 2. Wrong: Biomass has zero environmental impact because it is carbon neutral Correct: Biomass still produces CO₂ when burned and requires land to grow, which can lead to deforestation and habitat loss — carbon neutral only applies if replacement plants are grown 3. Wrong: Renewable energy sources are always the best choice Correct: Renewables can be unreliable (wind and solar depend on weather), may have high setup costs, and can cause environmental damage (e.g. flooding valleys fo
AO3 - Reasoning & Interpretation: Analysis and Evaluation The table below shows the electricity generation mix for two countries in 2024: Country A: Coal 5%, Natural gas 35%, Nuclear 20%, Wind 25%, Solar 10%, Hydro 5% Country B: Coal 45%, Natural gas 15%, Nuclear 0%, Wind 10%, Solar 20%, Hydro 10% (a) Calculate the percentage of electricity generated from renewable sources for each country. (b) Country B plans to close all coal power stations by 2035 and replace them with wind and nuclear. Explain one advantage and one disadvantage of this plan. (c) A politician from Country B claims "We should replace all coal with solar because solar is the cheapest renewable." Evaluate this claim using the data. Answers: (a) Country A ren
