Fuels are materials that react with other substances to release nulear or chemical energy as heat. Chemical fuels release energy via combustion. Nuclear fuels release energy by nuclear fission. Nuclear and chemical fuels are used for different purposes because of the complexity of deriving heat from them, the amount of heat generated and use in various applications.
