Energy

• How does coal work?

  Coal makes a lot of heat. This turns it into water vapour and it turns the turbines generating electricity
• What are the advantages of Coal?

  .Its easy to find as there is a lot of it stored underground

  .its reliable
• What are the disadvantages of Coal?

  .It causes air pollution

  .releases carbon

  .it warms up the planet
• How does Natural gas work?

  It burns to create heat which turns the turbines generating electricity.
• What are the advantages of Natural gas?

  It is very flexible as you can turn it off and on
• What are the disadvantages of natural gas?

  it releases greenhouse gases
• how does fracking work?

  Blasting water and chemicals into rocks shake out energy trapped inside
• what is the advantages of fracking?

  .allows us to access energy reserves

  .brings jobs to areas that need it
• what are the disadvantages of fracking?

  .it could ruin water supplies

  .causes mini earthquakes
• How does nuclear energy work?
