Go to Specific Heat CapacityWhat is National & Global Energy Resources?
National and global energy resources are the sources from which we generate electricity. These are categorised as renewable (e.g., solar, wind, tidal) and non-renewable (e.g., fossil fuels like coal, oil, and gas, and nuclear). The UK's energy mix is shifting towards renewable resources to reduce carbon emissions and combat climate change.
Board notes: Covered by all major boards (AQA, Edexcel, OCR). The specific case studies or statistics you need to know may vary.
Step-by-step explanationWorked example
A wind turbine has a power output of 2 MW. If it operates for 24 hours, how much energy does it produce in MWh? Solution: Energy = Power x Time. Energy = 2 MW x 24 h = 48 MWh.
Mini lesson for National & Global Energy Resources
1. Understand the core idea
National and global energy resources are the sources from which we generate electricity. These are categorised as renewable (e.
Can you explain National & Global Energy Resources without copying the notes?
2. Turn it into marks
A wind turbine has a power output of 2 MW. If it operates for 24 hours, how much energy does it produce in MWh?
Underline the method, evidence, or command-word move that would earn credit in GCSE Energy.
3. Fix the likely mark leak
Watch for this mistake: Confusing renewable and non-renewable resources. A common mistake is thinking nuclear energy is renewable; it is non-renewable because it relies on uranium, a finite resource.

Exam board
How should you use board notes for National & Global Energy Resources?
Covered by all major boards (AQA, Edexcel, OCR). The specific case studies or statistics you need to know may vary.
Common mistakes
- 1Confusing renewable and non-renewable resources. A common mistake is thinking nuclear energy is renewable; it is non-renewable because it relies on uranium, a finite resource.
- 2Not being specific about the advantages and disadvantages of each resource. For example, just saying 'wind power is good for the environment' is not enough; you need to mention that it is carbon-neutral but can be unreliable and a visual/noise pollutant.
- 3Mixing up the terms 'national' and 'global'. National energy resources refer to those available within a country, while global resources are traded and used worldwide.

Frequently asked questions
What is the difference between a renewable and a non-renewable energy resource?
A renewable energy resource is one that can be replenished naturally in a short timescale, such as solar or wind. A non-renewable resource is finite and will eventually run out, such as fossil fuels.
Why is the UK investing in renewable energy?
The UK is investing in renewable energy to meet its targets for reducing greenhouse gas emissions, to improve energy security by reducing reliance on imported fuels, and to create new jobs in the green economy.
