It's a distinction without a difference. Energy is not not a substance. Is a meaure of an entire configuration of states. Forms of energy is an "interpretation", a metpahor. C02 + H20 has less energy than CH3 + O2, because C02 + H20 are more stable (= lower energy) bonds. You can say the energy is in the electron, released as it falls into a lower energy state (bond). If I walk up a hill to a cliff, am I then in a more energetic state? No, because it takes energy to push me off the cliff, the ground is a more stable position than the top of the ledge and the appparent energy released by me turning a windmill I hit on the way down is because more energy is released by freefalling off a cliff than by sitting down on top of the ledge? or Yes, for exactly the same reason?
