  • RENEWABLE ENERGY
    • POWER FROM THE GROUND
      • ADVANTAGES
        • It does not give off greenhouse gases
        • Cheap once built as it is an infinite resource.
        • It can cut energy costs by up to 70%
      • DISADVANTAGES
        • It is expensive, costing approximately £12,000 to install.
        • Enough space is needed in the garden to install the pipework.
      • Ground source heat pumps take heat from the ground into the house. These supply warmth to radiators or under floor heating systems.
    • WATER
      • ADVANTAGES
        • It does not give off greenhouse gases.
        • Cheap once built as it is an infinite resource.
        • Can produce large bodies of water for leisure purposes.
      • DISADVANTAGES
        • They alter the water flow of rivers, affecting ecology.
        • Can only be built in certain areas due to dam requirements.
        • 40 - 80 million people globally have had to move because of dam construction.
      • Hydroelectricity is power from water. Rivers are dammed and the flow of water is controlled. The water turns a turbine which generates electricity.
    • TIDAL
      • ADVANTAGES
        • It does not give off greenhouse gases,
        • Cheap once built as it is an infinite resource.
        • Tidal barrages can also be used as bridges.
      • The movement of sea water drives turbines which produce electricity.
      • DISADVANTAGES
        • Can be a problem for shipping if built across an estuary.
        • Can be very expensive to build.
        • Can negatively affect wildlife.
    • WIND
      • Turbines which rely on the force of the wind to power blades which generate electricity.
      • ADVANTAGES
        • New wind turbines are quiet and efficient. Costs £1500 for 1kW.
        • It does not give off greenhouse gases.
        • Wind turbines can be on land or sea.
        • Can save up to 30% of the average household's energy bill.
      • DISADVANTAGES
        • There needs to be an annual local wind speed of more than 6 metres per second.
        • Require regular servicing.
        • They can be unsightly and visually intrusive.
        • Offshore turbines may disturb migration patterns of birds.
    • SUN
      • Photovoltaic cells - These are panels or tiles which produce energy (electricity) from light, preferably sunlight.
  • ADVANTAGES
    • Is fitted onto buildings and therefore does not take up extra land space.
    • It does not give of greenhouse gases.
    • Fairly cheap to set up, approximately £4000 per home.
    • There are no running costs.
    • Can provide up to 35% of a house's hot water.
    • Photovoltaic cells - These are panels or tiles which produce energy (electricity) from light, preferably sunlight.
  • DISADVANTAGES
    • Solar panels - fluid in panels on a roof heats up producing hot water for use.
      • Not efficient in countries where the sun rarely shines.
      • Cannot be mass produced so is best used on a small scale.
      • Photovoltaic cells cost approximately £12,000 for each home.

    Mr A Gibson

    Clarity and accuracy make this mind map a good one to print out and familiarise yourself with the renewable energy types.

    Use this with the mind map on non-renewables to get the full picture - access this here.
