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 the reservoir.
Water then goes through the intake, and rushes down the penstock. The water hits the turbine and spins it very fast.
This makes electricity which is stored in the generator. The electricity then travels through the power lines to houses and cities.
After the water has gone through the turbine, it rejoins the river.
You can make power in all sorts of ways but this is hydro power.
Power is very important, please save power . A hydro-dam is also called a hydro-station.
WAL about different power sources (where we get power from), and whether they are renewable or non-renewable:
Renewable (will not run out) energy source:
solar (sun)
wind
water
plants/animals (biomass)
geothermal
Non-renewable (will run out) energy source:
oil (petroleum)
coal
natural gas
This is how wind is used to generate (make) power:
The process behind wind energy is pretty simple. It starts, of course, with the wind, which is actually a form of solar energy. Wind is caused by the sun’s heating of the atmosphere, the irregularities of the earth's surface and its rotation.
The wind turbine captures that energy through propeller-like blades attached to a rotor, usually atop towers to access faster, less turbulent wind. Turbines can operate at variable or fixed speeds. Most new projects use variable speed as it more efficiently converts wind to electricity.
