Hydro- Power Explanation

WALT write an explanation 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 a reservoir.

It then goes through the intake then goes through the penstock.
Then this makes electricity which is stored in the generator.

The water hits the turbine and it spins very fast.The electricity then travels through the power lines to houses and cities.

Renewable energy resources,such as wind,solar and hydro-power,offer clean alternatives to fossil fuels. They produce little or no pollution or greenhouses gases, and they will never run out.
