Name the three fossil fuels.
• Coal • Oil • Natural gas
List some non-renewable energy resources.
• Coal • Oil • Natural gas • Nuclear fuel
List some renewable energy resources.
• Bio-fuel • Solar • Tidal • Hydro-electricity • Wind
Describe the difference between renewable and non-renewable energy resources.
Non-renewable energy resources are finite resources, whereas renewable resources are renewed as they are used
Describe what ‘bio-fuels’ are.
Renewable energy resources created from plant products or animal dung - they can be burnt to produce electricity or run cars in the same way as fossil fuels
Give some disadvantages to using bio-fuels.
• They cannot respond to immediate energy demands • The cost to refine bio-fuels is very high • Some worry that growing crops for bio-fuels will occupy the space and water needed to grow crops for food • Large areas of forest have been cleared to grow bio-fuels - burning of this vegetation has led to an increase in carbon dioxide emissions
Give some advantages to using non-renewable energy resources.
• They are reliable - there is plenty of fuel to meet the current demand for energy, meaning they can be used to respond quickly to changes in demand • Cost to extract fossil fuels is low, and power plants are cheap to build and run
Give some disadvantages to using non-renewable energy resources.
• Fossil fuels release carbon dioxide into the atmosphere when burned, contributing to global warming • Burning coal and oil can release sulfur dioxide, which causes acid rain • Oil spillages cause serious environmental problems • Nuclear waste is very dangerous and difficult to dispose of
