Origins+of+Wind+Power

**Origins of Wind Power**: Energy from the sun does not strike earth’s surface evenly; air above the equator absorbs more energy from the sun than the air above the poles. This difference causes air to move in currents. Because warm air is less dense than cool air, the warm air is lighter and it rises above the cooler air. As warm air rises, colder air flows in to replace it, causing wind. These winds contain huge amounts of kinetic energy, or energy contained in any fluid body of motion. Back to Home Page
