When you burn fuel, energy is transferred from the fuels chemical energy store to the thermal energy store of surroundings.
Energy is transferred to a light bulb electrically.
How is energy transferred away from a light bulb?
Via light and h eating
As an object falls, energy is transferred from its gravitational energy store to its kinetic energy store.
