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.
 |
| 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.
