RENEWABLE ENERGY
Energy that is collectable from resources that will never run out or which will be naturally replaced within a human lifetime
Renewable energy isn't always as good as it seems for environment as it can damage habitats or cause visual pollution to those around.
SOLAR ENERGY- energy from sun
The earth gets heat and light energy from the sun all the time
You can change it into electrical energy to power your home
WIND ENERGY-energy from the wind
Using wind turbines, we can turn the kinetic energy of the wind into electrical energy.
Which can power our homes
HYDROELECTRIC ENERGY-energy from rivers
Is a power station water behind a dam in a reservoir
This water has gravitational potential energy
TIDAL ENERGY-energy from sea tides
Sea levels go up and down due to sea tide
When the tide is high the water has lots of gravitational potential energy to turn into electrical to power homes
WAVE ENERGY- energy from sea waves
The sea waves have kinetic energy using machines
This energy can be turned into electrical to power homes
BIOMASS ENERGY- energy from plants and trees
The chemical energy stored in things that were once alive can be turned to heat energy burning them or electrical for powering homes
GEOTHERMAL ENERGY-energy from the earth
Deep underground the earths rocks are naturally very hot we can use their heat energy and turn into electrical energy for homes
NON-RENEWABLE ENERGY
Energy that has a finite supply means it will run out at some time
Fossil fuels like oil, natural gas and coal are considered non renewable and can not be replaced within a human lifetime
NUCLEAR ENERGY
Produced by either uranium or plutonium ores as a fuel are not infinite and will run out
They are a non-renewable source
NUCLEAR ENERGY- How it works
The reactor generates heat and a heat exchanger is used to transfer heat energy from reactor to the water
The water turns into steam and drives the turbines which turn electivity generators
