What are the Largest sources of energy on earth?

Answer 1

Answer is solid fuel( anthracite , bituminous , lignite , peat) liquid , gaseous fuels such as petroleum , natural gas,water power , energy of nuclear fission

--------------------------------------------------------

All the energy (apart from nuclear energy and geothermal energy) comes from or came from the Sun.
