#0183;#32;Bituminous coal is lower quality and easier to mine than anthracite. It is burned to produce electricity and run trains. Bituminous coal can produce excessive soot and smoke when burned, so its not ideal for heating, especially in coal or woodburning stoves in the home. Bituminous coal is also used to produce coke and to make iron and steel.
Natural gas is the third highest energy source in Australia (after oil and coal).
