Fossil Fuel. Nuclear energy comes from the energy stored in the nucleus (core) of an atom. This energy is released through fission (splitting atoms) or fusion (merging of atoms to form a larger atom). The energy released can be used to generate electricity. Fossil fuels—which mainly include coal, oil and natural gas—fill the majority of ...

Brown and black coal are mostly used as a source of fuel for power stations. Burning the coal produces heat which is used to make steam, so the the coal is sometimes called thermal or steam coal. The steam spins turbines to generate electricity. In Australia in 2017 coal was used to produce about 60% of the nation's electricity requirements.
