Thermal energy can be transferred by conduction, convection and radiation. When a person pushes another on the swings, they transfer their kinetic energy as seen when the person being pushed goes higher. Energy can be transmitted or converted, but it cannot be destroyed, according to the law of conservation of energy. When energy is not being used, it is called potential energy.
