The energy in butane, or in any compound for that matter, is stored in the chemical bonds that hold the atoms together. It takes energy to break those bonds, and then energy is released when new bonds are formed. If the energy needed for burning butane is less than the energy generated when the new bonds are formed in CO2 and H2O, then you get useful energy being produced.
Butane is a longer hydrocarbon (4 carbons in a chain, as compared to ethanes 2), so it has more energy stored up in the bonds. This means that it will release more energy when it is broken apart and new molecules are formed from it.
From the energy stored in light.
Potential energy is stored energy. The potential energy stored in chemical compounds is Chemical Energy. Chemical energy is energy stored in the bonds of atoms and molecules.

Potential energy is called stored energy because it is an energy that is not being used but ready to be used.
Butane is a longer hydrocarbon (4 carbons in a chain, as compared to ethanes 2), so it has more energy stored up in the bonds. This means that it will release more energy when it is broken apart and new molecules are formed from it.

it depends on whether your starving or not. if not, it comes from food (measured in calories). otherwise, your body's' energy will come from stored fat, stored glucose (often in the liver) and lean body tissue (muscle).
