Hydro power is renewable because even if it comes off the Earth it will come back.

How my energy source is made or found?

• In the 1800s, scientists learned how to use flowing water to spin the turbines of a generator.
• The first hydroelectric power plant in the U.S. opened on the Fox River near Appleton, Wisconson.

Advantages

• Once a dam is constructed electricity can be produced at a constant rate.
• If electricity is not needed the sluice gates can be shut, stopping electricity generation.

Disadvantages

• Dams are extremely expensive to build and must be built to a very high standard.
• The high cost of dam construction means that they must operate for many decades to become profitable.

FACTS

• In 2006, hydroelectricity supplied around 20% of the world's electricity
• Hydro power has a new technology called the hydro engine.
• Hydro power uses the energy of moving water for many applications.
• The largest hydroelectric power station in the world is the Tree Gorges dam in China
