Fossil fuels (coal, oil and gas)

  • Fossil fuels are made over millions of years and have a high carbon content.
  • Electricity is generated from the steam off of heated water turning turbines.
    • This water is heated by burning fossil fuels.
  • Carbon dioxide concentrations in the atmosphere increase because the carbon from this process gets released into the air.
  • Fossil fuels are also used to power cars, planes and ships in the form of petrol and diesel.

Renewable fuels

  • Renewable fuels are fuels which will not run out.
  • Types of renewable fuels include:
    • Solar (sun) energy.
    • Wind energy.
    • Wave energy.
    • Tidal energy.
    • HEP (Hydro-electric power).
    • Geothermal energy.
    • Biofuels.
  • They don’t pollute the environment much and are sustainable.
  • However, they are not perfect because they can be very expensive to produce.

Energy mix/ratio

  • This is the proportion of the amounts of renewable and non-renewable power used.
  • This can be determined at any scale (world-wide/national/regional/local).

National grid

  • This is the system through which electricity is moved around a country, using a network of wires and pylons.
