Hydro Power Explanation

WALT write an explanation including a definition, description and conclusion (of how a Hydro-power station works)





A hydro dam is an amazing structure that makes electricity from water!

firstly you build a dam to block the river .Water then builds up behind the dam. This is called the reservoir.

Water then goes through the intake, and rushes down the penstock, then the water spins the turbine.

This makes electricity which is stored in the generator. The electricity travels through the power lines to houses to cities.

After the water has gone through the turbine,it rejoins the river.

Hydropower is great because it is renewable.
