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
