  • The materials below will provide all the background information on the issue and key exam tips needed to tackle the questions in the 2025 Geography Paper 3 successfully

  • The materials will support you to:

    • set the issue in context, including where it is and the key facts about the location

    • examine conflicting stakeholder viewpoints regarding the issue

    • make an appraisal of the advantages and disadvantages

    • evaluate any alternatives

  • In the exam, you will need to answer various questions about the proposal for a tidal barrage across Morecambe Bay and Duddon Estuary in North West England

  • You will have about 35-40 minutes for this section of the exam

    • There will be a series of short skills questions (2-3 marks), followed by 6-mark extended questions and then a final 9-mark question which asks you to decide on the issue

    • You will be asked whether you agree or disagree with a statement and then you will be expected to explain your answer.

      • It does not matter whether you agree or disagree; what matters is how you justify your answer using evidence from the materials in the resource booklet and your knowledge

  • The issue evaluation skills guide is also here to help you

  • It provides support on interpreting and using the sources that you have available in the booklet

UK energy use

  • Energy sources are categorised into:

    • Primary energy – fossil fuels, waste, wind, solar, tidal, HEP, etc.

    • Secondary energy – petroleum products, fuels, electricity, heat and gases

  • These energy sources are essential for most daily activities, from boiling a kettle and playing on a game console to driving a car

  • Energy supports the population's well-being, transport, industry and domestic use

Flowchart detailing energy uses: provides light, powers transport, warms/cools homes, powers appliances, drives manufacturing, vital for communications.
Figure 1 - Energy use
  • Overall energy consumption per person in the UK has fallen by 35% since 1990

Figure 2 UK energy consumption per person

Source: Our World in Data

  • As well as the overall downward trend of energy consumption, there may be specific events which impact energy consumption

    • In 2020, the amount of energy consumed in the UK fell by 13% due to the lockdown during the Covid-19 pandemic

Worked Example

Using Figure 2, describe the change in UK energy consumption from 1990 to 2023.

[2 marks]

Energy consumption in the UK has decreased since 1990 [1] from about 40,000 kWh to just under 30,000 kWh in 2023. [1]

Worked Example

Using Figure 2, what impact did the Covid-19 pandemic have on energy consumption?

[2 marks]

The Covid-19 pandemic led to a decrease in energy consumption [1] because industries, transport and other workplaces were shut down. [1]

Examiner Tips and Tricks

It is important when interpreting graphs to identify any anomalies and consider why they might occur.

Energy use by sector

  • The amount of energy used by each sector varies:

    • Industry and domestic use of energy have both decreased since 1990

    • Whereas energy use by services has remained steady

    • Energy use for transport has fluctuated, experiencing a significant decrease in 2020 due to the Covid-19 lockdown

Line graph showing UK's energy use (1990-2023) in million tonnes of oil equivalent for domestic, industry, transport, and services; transport leads.
Figure 3 - UK energy use by sector
  • The reduction in energy use in industry and for domestic use is the result of:

    • decreasing manufacturing industry

    • reduced domestic consumption due to more energy-efficient appliances and energy-saving strategies such as double-glazing and insulation

Worked Example

Using Figure 3, calculate the change in energy consumption by UK industry between 1990 and 2021.

[1]

1990 = 39 million tonnes of oil equivalent

2021 = 21 million tonnes of oil equivalent

39 - 21 = a decrease of 18 million tonnes of oil equivalent or 46%

Examiner Tips and Tricks

It is a good idea to create a glossary of the key terms covered in the pre-release materials. Many of these key terms have been defined in these resources.

This will help you feel confident about what those terms mean when writing about them in the exam. A few of the terms you could include in your glossary are:

  • energy consumption

  • ecosystems

  • energy security

  • fossil fuels

  • renewable energy

  • energy demand

  • energy mix

  • sustainability

  • nuclear energy

  • tidal barrage

  • multiuse project

UK energy mix

  • Since the 1990s there has been a change in the UK energy mix

Stacked area graph showing UK energy consumption (1990-2020) in MTOE. Main sources: coal, oil, gas, nuclear, bioenergy, and renewables.
Figure 4 - UK's energy mix over time
  • The UK's reliance on fossil fuels has reduced and the use of renewable energy sources has increased

  • However, in total energy consumption, the UK remains reliant on fossil fuels, as shown in Figures 3 and 4

    • Approximately 80% of all UK energy is from fossil fuels

Pie chart showing UK energy sources: Oil 39.7%, Gas 36.2%, Renewables 14.4%, Nuclear 6.4%, Coal 3.3%. Includes a colour-coded key.
Figure 5 - percentages of UK energy mix

Electricity generation

  • Only 55% of power in the UK is produced using fossil fuels, despite the fact that they account for 80% of all energy

  • It is estimated that the demand for electricity will increase by 50% by 2030

Pie chart showing energy sources: Wind 29.4%, Gas 25.9%, Imports 15.7%, Biomass 13.7%, Nuclear 6.7%, Solar 4.9%, Hydro 1.8%, Coal 1.3%, Misc 0.6%.
Figure 6 - pie chart showing sources of energy for electricity generation in the UK in 2024

Worked Example

Using Figure 4, explain the changes in the energy mix of the UK

[4 marks]

Coal has decreased in the UK's energy mix from approximately 50 MTOE to less than 5 MTOE [1]; this is the result of the coal-fired power stations being closed down. [1]

The use of renewable energy sources such as wind and solar has increased [1]. This growth is due to improvements in technology and reductions in the cost of renewable energy [1].

Examiner Tips and Tricks

It is important to understand that there are significant differences in the mix of energy sources used for total energy consumption and those used for electricity generation. Think about what the most notable difference is and why that might be.

UK energy security

Energy security

  • The UK is increasingly dependent on energy imports

  • This has a significant impact on the country's energy security

  • Energy security refers to the ability of a country to ensure an accessible, available, affordable and acceptable supply of energy

    • Accessibility is the presence of energy sources so that all people, even in remote rural areas, can access energy supplies

    • Availability of energy means there is a sufficient, reliable and uninterrupted supply

    • Acceptability considers whether the energy supply is environmentally sustainable and safe

    • Affordability means that energy can be afforded by businesses and individuals and that people are not in 'energy poverty'

Factors affecting energy security

  • Physical factors 

    • Some countries have plentiful energy supplies due to their location

    • Their geology means that they have coal, oil and/or gas supplies,for example Qatar has surplus energy due to the supplies of gas

    • Location can also impact the availability of geothermal or hydroelectricity

  • Cost of exploitation

    • The economic viability of an energy source is whether the cost of exploiting the energy source is less than the money it will make

    • This can fluctuate depending on energy prices and demand

    • Some forms of energy are more expensive than others: coal is relatively cheap, whereas nuclear is expensive

    • The cost of renewables is decreasing as technologies develop

  • Technology

    • New technological developments mean that additional reserves of energy can be exploited

    • Technology has helped to improve the efficiency and cost of renewable energy; there are also developments in energy storage

  • Political factors

    • Conflict can be caused between countries regarding energy reserves and who has the right to exploit them

    • Flows of energy from one country to others can be interrupted due to conflict

      • Supplies of oil from Libya have been affected since 2011 by the civil war

      • The invasion by Russia into the Ukraine has affected supplies of gas

Worked Example

Define the term energy security.

[2 marks]

Energy security is the uninterrupted supply of energy [1] from acceptable sources at an affordable price. [1]

Examiner Tips and Tricks

Ensure that you learn the definitions of the 4 A's of energy – accessibility, availability, acceptability and affordability. It is important to consider the factors which affect the UK's energy security.

UK energy imports and exports

  • In 2021, the UK imported 62% of its gas supply and 18% of its oil

    • It is estimated that this will increase in the future

    • Most of the gas is imported from Norway

Graph showing UK net energy imports as a percentage of primary supply from 1970-2016, with notes on energy deficit above 0% and surplus below 0%.
Figure 7 - UK net energy imports
  • The UK is currently a net importer of energy, leading to energy insecurity

  • Consequences of energy insecurity can include:

    • Increasing energy prices

    • Exploration of environmentally sensitive areas for energy

    • Reduced industrial output

    • Reduced food production

    • Possibility of power outages

Worked Example

Using Figure 7, explain when the UK had the greatest energy security.

[2]

Between 1981 and 1988 and between 1993 and 2004 [1], the UK was exporting more energy than it was importing, meaning that it had an energy surplus. [1]

Examiner Tips and Tricks

The proposed tidal barrage is a renewable energy source. When completed, it is estimated that it will generate enough energy for 2 million homes. You need to consider the advantages of the scheme in terms of the type of energy and the impact on energy security.

Types of energy sources

  • All energy sources have both economic and environmental impacts

Fossil fuels

Economic issues

  • Non-renewable energy sources: will eventually run out or will no longer be economically viable

  • Issues with obtaining energy sources include oil spills, and job-related diseases (miners) lead to additional costs 

  • Costs related to the impacts of climate change and adaptations 

Environmental issues

  • Greenhouse gas emissions which contribute to global warming

  • Waste created by mining and oil spills can damage ecosystems

Nuclear fuels

Economic issues

  • The building and decommissioning of nuclear power stations is expensive

  • The cost of storage, transport and disposal of nuclear waste is high

Environmental issues

  • Dangers associated with the storage and disposal of radioactive waste

  • Risk of nuclear accidents which would harm humans and wildlife

Renewable energy

Economic issues

  • Set-up costs are high

  • The visual impact of wind and solar farms may lead to a decrease in tourism which impacts the local economy

Environmental issues

  • Visual impact of wind turbines and solar panels

  • Wind turbines may affect bird migration patterns and bat flight patterns

  • Dams built for hydroelectric power may affect fish and wildlife movement along the river. They also block sediment, reducing deposition downstream. Large areas need to be flooded, destroying habitats and ecosystems.

  • Reduce emissions of greenhouse gases 

Renewable energy in the UK

  • The UK's energy strategy aims to reduce the reliance on fossil fuels for three main reasons:

    • Oil, gas and coal reserves are running out

    • Fossil fuels emit greenhouse gas emissions which contribute to global warming

    • The last coal-fired power station closed in 2024

  • Renewable energy sources are increasingly important because:

    • They do not emit greenhouse gases when generating electricity (although some greenhouse gases are emitted in the manufacture and construction of renewable energy sources)

    • The cost of renewable energies is decreasing

    • They will not run out

    • They are less likely to be affected by international conflicts

    • Energy prices are more stable

    • Maintenance costs are lower

Pie chart of renewable energy: 63% bioenergy, 26% wind & marine, 5% heat pumps, 4% solar/geothermal, 2% hydro, with colour-coded key.
Figure 8 - Pie chart showing the UK's renewable energy sources
  • Renewable energy sources include:

    • hydroelectric

    • marine – includes wave and tidal

    • wind

    • solar

    • geothermal

    • bioenergy/biomass
