ocr: How does a windmill convert energy? HEAT ENERGY KINETIC ENERGY ELECTRICAL ENERGI Some of the heat energy from the Sun heats up the atmosphere. Air currents, or winds, occur when air warmed by the sun, rises, and cool, heavy air sinks. This means that the heat energy of the Sun is converted into kinetic energy in moving air molecules. Modern windmills, known as wind turbines, convert the wind's kinetic energy into its own kinetic energy in its spinning blades. These drive generators which convert the kinetic energy into electrical energy. Over history, windmills have become better designed to t ...
