  • 2. ¿Qué es?
    It is a type of energy that takes advantage of the energy of the tides. There uses the difference of height between the tide and the low tide.
  • 3. It is a renewable energy, that is to say, a type of energy that takes advantage of resources that do not end, in this case, the water
  • 4. Tides
    The tides are periodic changes of the level of the sea that are different depending on the zones.
  • 5. The tides are produced by the attractive force of the Moon and, in minor measure, of the Sun. When in a place there is high tide, in other one there is low tide
  • 6. When the Sun and the moon attract in the same direction the alive tides are produced.
    If they attract in opposite directions, dead tides are produced
  • 7. In order that this energy works out profitable it is necessary that the difference between tides is major of 5 meters. Therefore only it is possible to install plants in a few places.
  • 8. The Plants
    Estuary of the river Adige (Italy)
    The tidal power stations must place in zones closed as the estuary of a river.
    The Guadalquivir
  • 9. A plantconsists of:
    Turbine Pelton
    A turbine "bulb" with arms or blades
    A bun
    - a camera of entry of the water
    - a pipe of aspiration
  • 10. Functioning
    1. When the tide rises, the hatches of the plant are opened to allow the step.
  • 11. 2. The deposit is closed creating a prey with the water dammed in its interior.
  • 12. 3. When the tide is in its point more low the hatches are opened to allow the step of the water along the turbines.
  • 13. 4. The turbines move the blades that, together with the alternator, produce alternating current.
  • 14. Tidal power station of the river The Rance
    It is the only tidal power station with energetic purposes of the world. Others only are used by scientific purposes.
  • 15. It is in the river mouth of the river The Rance, in the north of France. It is formed by 24 generators. It has a power of 240 MW
  • 16. The dike has 700 m of length and 15 of height. It produces 600 millions of kwh annual, the sufficient ones as to supply 330000 persons.
  • 17. Other tidal power stations are:
    Murmansk in Russia
    Annapolis Royal in Canada
  • 18. Advantages
    It neither emits any pollutant nor emits any dangerous residue
    It is a renewable energy.
    The cost of maintenance is low.
  • 19. Disadvantages
    Its cost is very high.
    The production of energy lasts only a few hours.
    It produces a great environmental impact.
  • 20. Resumen
    The wave energy is a clean energy, which takes advantage of the difference between tides and which does not produce pollutants but which is very expensive its construction, only one can in a few zones of the planet and that generates a great environmental impact.
