WHAT IS HYDRO-ELECTRIC POWER?

Hydro-electricity is one of the many energy sources used around the world. It is a form of energy that uses the force of moving water to generate electricity. Hydropower is used by building dams to trap the water.

WHERE IS THE BEST PLACE TO BUILD A DAM?

One of things you need to remember when building a

dam - is the location! The dam must be build near

valleys and rivers. The land can’t be flat, or there is no

way to build a dam. Dams can also built on rivers. Even

though most dams are build to generate electricity,

some dams are there just built to control flooding or to

irrigate farm land.

ADVANTAGESWhen it is in use, electricity produced by dam

systems, does not produce any pollution in the

atmosphere.

Hydropower can be used throughout the

world.

It is renewable.

Hydropower is always available, specially

when there is a great need for electricity.

DISADVANTAGES

Hydropower can impact water quality and flow. It can

cause low dissolved oxygen levels in the water.

Failures of large dams, would be great disaster because it

could kill so many people and could leave people homeless.

Building a large dam will flood a very large area upstream, which

will cause problems for animals that used to live there.

The fishes would get killed by the turbines.

The land around the dam can be destroyed.

FACTSHydro-electric is also known as hydropower.

Hydropower is a renewable energy because it's

replenished naturally by rain and snow.

It doesn’t cause pollution. Green and clean!!

It is the cheapest way to generate electricity.

Hydropower is from the Greek word “hudor”

meaning water.

MORE FACTS

Hydropower is one of the oldest source of

energy. The Ancient Egyptians used water

wheels to turn clocks and grind grain as early

as 250 B.C.

Canada is the largest producer of hydropower

in the world. The United States is second.
