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