  6. Wind • Wind energy is wind. This is also a renewable source of energy. • Wind turbines are used to convert this energy into electricity.-

  7. Turbine

  8. Advantages of Wind Energy • No pollution. • Renewable. • Stations can be made off shore as well as on land.

  9. Disadvantages of Wind Energy • If there is no wind then there is no power • Turbines are very expensive

  10. Geothermal • Geothermal energy is basically the heat from the earth. • It is mostly hot rocks under the ground that produce steam that powers turbines that creates electricity. • http://www.youtube.com/watch?v=-ajqiPe_9Ko

  11. Advantages of Geothermal Energy • If used in the correct way then there is no pollution • Stations are self sufficient energy wise • The stations do not harm landscape as the stations are very small
