Energy transferrs
-
-
-
-
radiation - energy transferred as a wave, eg light and infrared - light radiation and infrared radiation are emitted from the sun
-
Renewable energy soueces
Hydro electricity
-
The water has GPE that changes into KE when the water falls through pipes containing turbines, which spin as water rushes through.
-
-
Biomass
-
-
-
Can be stored until needed. No methane released into atmosphere. Produced smoke pollution. Can lead to deforestation
-
-
Tidal
-
After the tide goes out, gates in the barrage are opened.
Water rushes through the pipes, spinning turbines.
These turbines turn the generators, making electricity.
-
Waves
Small rafts move up and down with the water, or the movement of seawater in and out of a cavity on the shore compresses trapped air, driving a turbine.
These turbines turn the generators, making electricity.

Efficiency
-
-
The main ways of reducing unwanted energy transfers are lubrication and thermal insulation. Lubrication reduces unwanted friction. Thermal insulation reduces unwanted heat transfers
