1. In a hydro-electric power station, a dam is built to hold water at a high position so that potential energy is stored. When water flows down, potential energy is converted into kinetic energy. The running water drives a turbine which turn drives a generator to produce electricity.

2. @TheSingStarPrincess it is the force of the water due to gravity. the amount of energy a dam can hold is E=mgh (m=mass of water g=acceleration due to gravity (9.8) h=height difference of water levels) this ‘falling water’ spins the turbine in the same way water spins a water wheel. it is just that this mechanical energy (spin) is converted to electrical energy (electricity) by the generator

3. I am also doing a project on Hydropower! One Question, Is it the force of the water that creates the power? Please Reply

4. me & my group are using this for a science project, thanks.:)

5. hydroelectric generators, solar panels, and wind turbines are the only difference between us and the alien race that will enslave us someday

6. thank you sicince project too! lol

7. Onlyy 100,000 olympic pools? Sounds like too few to me…probably more like 500,000 a day.

8. @Naddy008
   lolz im so stereotypical i needed dis for a science project…. :P u prob feel special XD

9. sweet for my science project :P

10. thnx lol science project too XD

11. It’s us, Jasper/Rens/Martijn

12. needed this for a geoghrapy presentation :D
    thanks a lot!

13. In Sri Lanka we use hydro-electric power stations ONLY. No coal no nothing just water.

14. lol i needed this for a science project

15. i’m different i need it for a history project :P so ty

16. LOL. Like everyone else, I needed this for a science project.

17. Thx needed it for a science project

18. thanks needed this to write a pare for science helped alot

19. wow i didnt know all that, thanx for posting!

20. Earth comes first!!!

21. “this is how all nations should produce electricity”

    Other renewables are good too. Geothermal has less environmental impact.

    “not use nuclear power tt is destroying our beloved planet!”

    The amount of earth that nuclear power has damaged detectably is absolutely tiny. Transport does most of the damage. Then farming. Then fossil fuel power generation.

    “bastards that should not be supported!”

    True.

22. this is how all nations should produce electricity and not use nuclear power tt is destroying our beloved planet!
    the elite hates using the simple method as it doesnt cost too much, instead the elite uses the expensive ones at the back of the population! bastards that should not be supported! salut

23. Hmm, ohh got that later

24. I like this method better than the fossil fuel power. It’s much cleaner. I’d love to have something like this for my house as well as work on a project for heating as well. Just think…free electricity, free heating, and if you have a diesel powered car free gas when you collect over a thousand gallons of used cooking oil.

25. Excellent Video. Thanks.
