  1. Hydro-electricity Sven, Maxim, Robbe, Siri, Julie and Eline

  2. Hydro-electricity Introduction video What? How much/many? Pro’s and contra’s Otherways in Norway? Otherways in Belgium? How weshould save energy?

  3. Introduction video http://www.youtube.com/watch?v=rnPEtwQtmGQ

  4. What? Hydro-electricity is the most widely used form ofrenewableenergy (16% of global electricitygeneration) Basedon 2 things: The difference in heigth The flowof water

  5. What? • Electricity

  6. In Norway Hydro-electricity = 99% 200 power plants More than 800 small river plants

  7. In Sykkylven 3 power plants 6 small river plants

  8. In Sykkylven Power plant + Water plant = unique By goingthroughthepower plant, the water loses his verystrongpressure. So it cangothrough a water plant too. (otherwisethepressurewould be to high)

  9. In Belgium Severalsmall river plants in Walloon No bigpower plants becausewedon’t have thedifference in height

  10. Pro’s Clean Renewable No CO2pollution

  11. Contra’s Impactonthelocalcommunity Plants aredestroyed in the area where it is built

  12. Otherways in Norway Windmills Waveenergy Thermalenergy

  13. Windmills

  14. Parts of a windmill Rotorblades 3 Rotorblades 26 rpm 52 meter Air Brakes

  15. Parts of a windmill Rotor Blade adjustment Main spindle Gearwheels Brake Generator Transformator Frame Anotherframe Sensors crane

  16. Pro`s No pollution Reduced dependence Job prospects/opportunities Cheap energy

  17. Contra`s Impact on the environment Impact on the landscape Annoying sounds Shadow pollution

  18. Waveenergy http://www.youtube.com/watch?feature=player_embedded&v=ILWXAkE4QpQ#! Waves => Wave Energy Converter (WEC) => Energy

  19. Thermalenergy • Generator http://www.youtube.com/watch?v=BHSNBzHCvMI

  20. Otherways in Belgium Windmills Solar panels

  21. Solar panels A lot in Belgium, few in Norway The lightofthesun is transformedintoenergy

  22. Pro`s No pollution Reduced dependence Job prospects Cheap energy

  23. Contra`s It’s ugly It needs a lot of cleaning

  24. Save energy? When we came to Norway we noticed that Norwegians don’t switch off the lights as quickly as we do in Belgium. That’s because energy is cheaper in Norway than in Belgium. So we can conclude that hydro-electricity is very important in Norway.
