Key Stage 3

Meaning

Hydroelectricity is an energy resource that uses the water flowing in rivers to generate electricity.

About Hydroelectricity

Hydroelectricity is a renewable energy resource.
Hydroelectricity has energy in the gravitational potential energy store of water that is flowing downhill.

Power

Hydroelectricity can be used to generate electricity.

HydroelectricDamDiagram.png
A diagram of a hydroelectric dam.
1. Water flowing down a river is held back by a dam making a large reservoir.
2. Some water is allowed through pipes to flow downhill.
3. This water turns a turbine as it falls.
4. The turbine causes a generator to spin.
5. The generator makes an electrical current.

Advantages

  • Reliable source as it is built in places that do not suffer drought.
  • Power provided can change at a moments notice by allowing more water through the turbines.
  • Low running costs and no fuel cost.

Disadvantages

  • Expensive to build.
  • Require the flooding of a large area of land.
  • Destroys habitat of some creatures.
  • Blocks the migration of some river species.
  • Can only be built in certain locations.
