What is the difference between renewable and non-renewable energy?

Renewable energy comes from sources that are naturally replenished, like sunlight, wind, and water. Non-renewable energy comes from finite sources like coal, oil, and gas, which take millions of years to form and will eventually run out. Renewables produce little to no greenhouse gases, while non-renewables release CO2 when burned.

Why is there increasing demand for energy?

Global energy demand is rising due to population growth, economic development (especially in countries like China and India), and increased use of technology. As people become wealthier, they use more appliances, cars, and electronics, all of which require energy. Urbanisation also concentrates energy use in cities.

What is the UK's energy mix?

The UK's energy mix in 2023 was roughly: natural gas 40%, renewables (wind, solar, biomass) 30%, nuclear 20%, and coal less than 5%. The mix changes over time as the UK phases out coal and expands renewables. Imports also play a role, especially for gas and electricity from France.

How can we reduce energy demand?

Energy demand can be reduced through conservation (e.g., turning off lights), improving energy efficiency (e.g., LED bulbs, better insulation), and using smart grids to manage consumption. Government policies like carbon taxes and building regulations also encourage lower demand. Individuals can also choose public transport or cycling.

What are the advantages and disadvantages of wind power?

Advantages: Wind is free, renewable, and produces no emissions. It can be built on land or offshore. Disadvantages: Wind turbines are noisy, can harm birds, and are intermittent (they only generate when wind blows). They also require large areas and have high upfront costs, though these are falling.

Is nuclear energy renewable?

No, nuclear energy is not renewable because it relies on uranium, a finite resource. However, it is low-carbon and can provide reliable baseload power. Some argue it is a sustainable option for reducing emissions, but it produces radioactive waste that must be stored safely for thousands of years.

There is increasing demand for energy that is being met by renewable and non-renewable resources

Topic Overview

This topic explores the growing global demand for energy and how it is met by both renewable (e.g., solar, wind, hydroelectric) and non-renewable (e.g., coal, oil, natural gas) resources. As populations rise and economies develop, energy consumption increases, particularly in emerging nations like China and India. The UK also faces challenges in balancing energy security with environmental commitments, such as the transition to net-zero emissions by 2050.

Understanding this topic is crucial because energy choices have profound economic, social, and environmental impacts. Non-renewable resources are finite and contribute to climate change through greenhouse gas emissions, while renewables offer sustainable alternatives but face issues like intermittency and high initial costs. The topic also covers energy security, the concept of energy mix, and the role of government policies in shaping energy futures.

In the Edexcel GCSE Geography course, this topic fits within the 'Changing Cities' and 'Resource Management' units. It links to broader themes of sustainability, climate change, and global inequalities. Students should be able to evaluate the costs and benefits of different energy sources and discuss strategies for managing energy demand, such as conservation and technological innovation.

Key Concepts

Core ideas you must understand for this topic

→Energy security: The uninterrupted availability of energy sources at an affordable price. Countries with diverse energy mixes are more secure.
→Renewable vs. non-renewable: Renewables (e.g., solar, wind, tidal) are replenished naturally; non-renewables (e.g., coal, oil, gas) are finite and take millions of years to form.
→Energy mix: The combination of different energy sources used by a country. The UK's mix includes gas (40%), renewables (30%), nuclear (20%), and coal (less than 5%).
→Carbon footprint: The total greenhouse gas emissions caused by an individual, event, or product. Energy production from fossil fuels is a major contributor.
→Sustainable energy: Energy that meets present needs without compromising future generations. This includes renewables and energy efficiency measures.

Examiner Tips

Expert advice for maximising your marks

💡Ensure you can define and classify resources as biotic, abiotic, renewable, and non-renewable
💡Use specific examples of energy management strategies for both a developed and an emerging/developing country
💡Be prepared to interpret line graphs showing future population projections in relation to energy resources
💡Practice calculating carbon and ecological footprints as part of your revision
💡Use the command word definitions provided in Appendix 3 to structure your answers, especially for 8-mark extended writing questions
💡Use specific examples and data. For instance, quote the UK's renewable energy percentage or compare energy consumption per capita in different countries. This shows depth of knowledge.
💡Evaluate rather than describe. In 6-mark questions, discuss pros and cons of different energy sources. For example, 'Wind power is clean but intermittent; gas is reliable but emits CO2.'
💡Link to wider issues. Connect energy demand to climate change, economic development, or government policy. This demonstrates synoptic understanding and can earn higher marks.

Common Mistakes

Pitfalls to avoid in your exam answers

Confusing renewable and non-renewable energy classifications
Failing to provide both positive and negative impacts for energy resources
Neglecting the role of different stakeholders in energy management decisions
Generalising energy management without referring to specific country examples (one developed, one emerging/developing)
Misconception: Renewable energy is always cheaper than non-renewable. Correction: While costs have fallen, renewables can be more expensive initially due to infrastructure. However, they have lower long-term operational costs and no fuel costs.
Misconception: Nuclear energy is renewable. Correction: Nuclear is low-carbon but not renewable because it relies on finite uranium. It is often classified as a non-renewable but low-carbon source.
Misconception: The UK gets most of its energy from renewables. Correction: In 2023, renewables provided about 30% of UK electricity, but gas still dominates at around 40%. The energy mix varies by year and weather conditions.
