crude oil
Oil
refining process
transportpipeline
extraction
A naturally ocurring thick, flammable liquid.
Remains of plants and animals
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
transport
liquification
extraction
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
cooling tower
transformer
generator
condensersteam generator
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
Plant materials
Hydroelectric energy
transformer
generator
Hydroelectric power station
lock gate
turbine
This is energy produced by the movement of water.

Solar energy
Lighthouse
This is energy derived from sunlight.
HomesPhotovoltaic solar power facility
Uses: heat, electricity
hot water out
cold water in
Solar water heater
Eolic energy
blades
tower
anemometer and wind vane
shaft
generator
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.
