- Year 8
Power stations
I can describe how burning fuels can be used to generate electricity.
Lesson details
Key learning points
- Over half of the electricity in the UK is generated from the Sun, wind and falling water.
- Many power stations in the UK burn natural gas and oil to heat water into steam.
- The moving steam in power stations pushes turbines, which drive electric generators that produce electricity.
- Natural gas and oil are fossil fuels used in power stations; coal is no longer used in UK power stations.
- Natural gas, oil, waste and wood are fuels that produce greenhouse gases and pollutants when burned.
Keywords
Electric generator - works like a motor in reverse, generating electricity when it is pushed round
Fuel - a substance that is burned for heating
Non-renewable resource - a resource that cannot be replenished
Pollutant - a substance that causes damage to air, water or land and is likely to harm living organisms
Greenhouse gases - gases in the atmosphere that keep it warmer than it would be without them
Common misconception
Power stations generate most of the electricity that we use in the UK.
Highlight how over half of UK electricity is now generated using renewable energy resources and that power stations contribute about a third of the electricity. Also highlight the continuing need for power stations due to varying weather and demand.
Equipment
None required.
