Why are carbon and its compounds used as fuels for most applications?

(N/A) Most carbon compounds release a significant amount of heat and light when burned in air.
Saturated hydrocarbons burn with a clean flame and produce no smoke.
Carbon compounds used as fuels possess high calorific values,meaning they release a large amount of energy per unit mass.
Due to these properties,carbon and its compounds are widely used as fuels for most applications.
