Renewable Energy
Bio gas
A mixture of methane and carbon dioxide
Can be burnt to help produce electricity
A product of biomass such as animal dung and human waste
Made by an anaerobic digester
Tidal Energy
Created by the moons gravity
Creates power from a tidal barrage
Makes electricity
Bio energy
Made by crops such as willow trees
Burns to make steam to power turbines
Plants can also be burnt to make bio energy
Hydroelectricity
Uses water from rivers
Its released through gates to create kinetic energy
The turbines are attached to generators to produce electricity
Tidal Stream
It uses fast sea currents that flow as the tides move
Sea currents turn turbines which generates electricity
I takes place underwater
Geothermal Energy
Comes from a layer of molten rock beneath the Earths crust
There are reservoirs of water underground
Boreholes are driven into the ground to bring water to the surface
The water can then be used for steam and electricity
