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

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

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.
