system as input to the system. Radiant energy, energy that is transported by waves Rotational energy, part of an object's total kinetic energy due to its rotation Solar radiation, radiant energy emitted by the sun, particularly electromagnetic energy Tidal power, also called tidal energy, is a form of hydropower that converts the energy of tides into useful forms of power - mainly electricity, dynamic tidal power, tidal lagoons, tidal barrages Wave power is the transport of energy by ocean surface waves, and the capture of that energy to do useful work — for example, electricity generation, water desalination, or the pumping of water (into reservoirs). Machinery able to exploit wave power is generally known as a wave energy converter (WEC). Wind energy is the kinetic energy of air in motion;Wind power is the conversion of wind energy into a useful form of energy, such as using wind turbines to make electricity, windmills for mechanical power, windpumps for water pumping or drainage, or sails to propel ships Allegorical and esoteric Energy (esotericism), invoked by spiritualists for alternative modes of healing the human body as well as a spirit that permeates all of reality.
