• mechanically transferring energy

  An object moving because a force is acting on it, like pushing, pulling, squashing, or stretching.
• thermally transferring energy

  Energy moving from a hotter object to a colder one through conduction or convection, like heating a pan of water.
• electrically transferring energy

  A charge moving through a voltage, like current flowing in a circuit.
• radiation as an energy transfer

  Energy is transferred by waves, like light or infrared.
• sankey diagrams
