Coal
Open pit mines
Underground mines
Uses: electricity, heat, steel
An organic sedimentary rock formed from plant material.
Anthracite coal produces the most heat.
gas pipeline
Natural gas

Uses:electricity, heat, fuel
Regasification facility
A gaseous fossil fuel, consisting mainly of methane.
It is found in oil felds, natural gas fields and coal beds.
Uranium

reactor core (uranium fuel)
control rods
turbine
A natural occurring element found in rock, soil and water.
Uses: heat, electricity and gases, such as ethanol
Biomass energy
This is energy obtained when organic matter is burned.
Energy crops
Organic waste

Wind turbine
This is kinetic energy produced by the wind.
Wind farm
Uses: heat, electricity
Geothermal energy
volcanic areas
hot springs and geysers
Uses: heating systems
This is energy generated by the heat from within the Earth.
Tidal energy
This is energy generated from ocean movement, mainly from tides.
SEE ANIMATION
High tide
Low tide
Energy is generated by the difference in height between high and low tide.
