Key Stage 3
Meaning
Biofuel is an energy resource made from plants and animals that have been grown to heat, light or to power electrical appliances.
About Biofuel
- Biofuel is a renewable energy resource.
- Biofuel has energy in its chemical potential energy store which can be transferred into a thermal energy store by combustion.
There are several types of biofuel:
- Wood
- Bio-ethanol
- Bio-diesel
- Bio-gas
Power
- 1. Biofuel is burned in a furnace.
- 2. The combustion of biofuel heats water in a boiler.
- 3. The water turns into steam and rushes down pipes.
- 4. The steam turns a turbine.
- 5. The turbine spins a generator.
- 6. The generator makes electricity.
Advantages
- Extremely reliable.
- When growing fuels Carbon dioxide is taken out of the atmosphere by the plants.
- Can be ‘carbon neutral’ as the same amount of Carbon Dioxide is taken out of the atmosphere to grow the biofuel as it put back into the atmosphere by burning them.
Disadvantages
- Cost of fuels is high.
- Large areas of land must be used to grow the fuel (this can mean cutting down forests for land).
- Burning the fuels produces carbon dioxide and if fuels are burned quicker than they can be grown then the produce more pollution.
