Coal, oil and gas are called "fossil fuels" because they have been formed from the organic remains of prehistoric plants and animals.Coal is crushed to a fine dust and burnt.Oil and gas can be burnt directly.The steam that has passed through the power station's turbines has to be cooled, to condense it back into water before it can be pumped round again.
