3. What is waterpower ? Hydro power, called hydro energy Is a renewable energy source Recovered energy is converted via generators in hydroelectric power plants As early as 3,500 years ago, China had in the former Mesopotamia and water wheels BACK

4. The first waterplants of the world The first water wheels were in China and the former Mesopotamia For irrigation in agriculture BACK

5. The new Waterplants It was possible to convert the rotary motion into a reciprocating motion Common prime mover Mostly in use by farmers and a blacksmith BACK

6. The potential of the technically exploitable hydropower depends … of the rainfall and the topographic conditions that are globally and regionally very different on geography BACK

7. The power plant today  the kinetic energy of the water is converted to mechanical energy or electrical energy  Thus, the water power for the people made ​​ useful BACK

8. The tidal power plant A tidal power station is a hydroelectric power plant, the potential and kinetic energy from the tides of the sea transformed into electricity Back

9. The largest hydroelectric plant in the world Three Gorges Dam On 14 December 1993 and construction completed in Feb. 2007 Is a dam with a hydroelectric power plant, a ship lock and a lock system in the Yangtze River in China Generator power of 18 200 megawatts (compared hydroelectric plant in Essen has 0.588 MW) Total cost of 75 billion dollar BACK

10. Information on consumption With water power plants in 2008 were won 15.8% of the world's electrical energy production (9.7% Europe) By comparison, nuclear energy by 2008 13.6% were obtained of the world's electrical energy production (27.8% Europe) In Germany there are 7300 active facilities BACK

11. Any more hydroelectric plants in future? Hydropower is currently the most important renewable energy source contributing to power the world's population One sees great growth potential of hydropower in the Third World, in densely populated Europe, a further expansion appears problematic BACK
