The energy produced during combustion is in the form of heat, light or both.Examples of fuel are wood, paper, coal, gas, oil and of course, propane.Following combustion (after the fuel has burned), byproducts are produced that move into the atmosphere.he energy produced during combustion is in the form of heat, light or both.
