Permission granted to reproduce for educational use only. © Goodheart-Willcox Co., Inc. Inexhaustible Energy Converters Prime movers use wind and water power, for example, to help boats move. Windmills and waterwheels convert natural mechanical energy (flowing air, running water) into controlled mechanical energy (rotary motion). Solar, geothermal, and ocean energy can be used to produce energy needed to heat and light homes.
