Kinetic and potential energy
Motion stores kinetic energy; position and configuration can store potential energy.
Thermal energy
Microscopic motion and interactions within matter are connected to temperature and thermal energy.
Chemical and electrical energy
Bonds, batteries and circuits provide familiar examples of energy storage and transfer.
Conservation does not mean usefulness is conserved
Energy remains accounted for while spreading into forms that can be less useful for doing work.
