• what is a fossil fuel?

  An energy source formed in the Earth's crust from decayed organic material. The common fossil fuels are petroleum, coal, and natural gas.
• Advantages of using fossil fuels

  • At the moment, fossil fuels are relatively cheap and easy to obtain. This may not always be the case.
  • Much of our infrastructure is designed to run using fossil fuels.
• Disadvantages of using fossil fuels

  • Fossil fuels are non-renewable energy resources. Their supply is limited and they will eventually run out, whereas fuels such as wood can be renewed endlessly.
  • Coal and oil release sulfur dioxide gas when they burn, which contributes to acid rain.
  • Fossil fuels release carbon dioxide when they burn, which adds to the greenhouse effect and increases global warming. Of the three fossil fuels, for a given amount of energy released, coal produces the most carbon dioxide and natural gas produces the least.
• how does a coal power station work?


  Electricity is made at a fossil plant by burning coal, which heats water in a boiler to produce steam. The steam, under a lot of pressure, flows into a turbine, and the turbine spins a generator to make electricity.
• how does a wind turbine generator work?


  As the wind blows, it transfers some of its kinetic energy to the blades, which turn and drive the generator producing electricity.
