Go to Water Insecurity & Access to Clean WaterWhat is Energy Security: Renewable vs Non-Renewable?
Energy security refers to having a reliable, uninterrupted, and affordable supply of energy. A country's energy mix describes the combination of different energy sources it uses, primarily divided into non-renewable (fossil fuels like coal, oil, gas) and renewable (wind, solar, hydropower). The UK is aiming to increase its energy security and reduce carbon emissions by transitioning away from imported fossil fuels towards domestically produced renewable energy.
Board notes: Energy security is a key part of the Resource Management topic for AQA and is also relevant to other boards. Students need to understand the difference between renewable and non-renewable sources and evaluate the costs and benefits of different energy strategies for the UK.
Step-by-step explanationWorked example
The growth of offshore wind in the UK: The UK has become a world leader in offshore wind power, taking advantage of its long coastline and shallow seas. Large wind farms like the Hornsea Project off the coast of Yorkshire can generate enough electricity to power over a million homes. This increases the UK's energy security by reducing reliance on imported gas and contributes to meeting climate change targets by providing low-carbon electricity.

Common mistakes
- 1Thinking that renewable energy is always perfectly reliable. Wind and solar power are intermittent – they don't work when it's not windy or sunny. This creates challenges for managing the electricity grid, requiring backup power stations (often gas-fired) or new energy storage solutions.
- 2Assuming that nuclear power is a renewable energy source. Nuclear power is a low-carbon source of energy, but it uses uranium, which is a non-renewable resource. There are also significant challenges regarding the disposal of radioactive waste.
- 3Believing that being energy secure means a country must produce all its own energy. Energy security can also be achieved through having a diverse range of energy sources and suppliers from politically stable countries, reducing reliance on any single source or country.

Frequently asked questions
What are the advantages of renewable energy?
Renewable energy sources like wind and solar produce no greenhouse gas emissions, helping to combat climate change. They are also inexhaustible and can increase a country's energy security by reducing the need for imported fossil fuels.
Why is the UK still using fossil fuels?
The UK is still heavily reliant on fossil fuels, particularly natural gas, for heating homes and for providing a reliable source of electricity when renewable output is low. The transition to a fully renewable energy system requires massive investment in new infrastructure and technology.
