Fossil fuels: Coal Petroleum oil Natural gas

Nuclear fuels:Uranium oil

Energy from the sun: Fusion (a nuclear reaction) involves small nuclei combining to form larger ones This process involves a loss of mass, with the lost mass being converted to energy Roughly 4 billion kg of mass is converted to energy every second in the sun
