Wind energy propelled boats along the Nile River as early as 5000 B.C. By 200 B.C., simple windmills in China were pumping water, while vertical-axis windmills with woven reed sails were grinding grain in Persia and the Middle East. New ways of using the energy of the wind eventually spread around the world.

Wind power uses energy from the moving air to turn large blades on windmills. In the past, the motion of the blades was used to grind flour or pump water, but now the blades turn turbines, which rotate generators in order to produce electricity. Wide open windy spaces are needed in order for this system to be efficient.

Structural protection from wind hazard. As noted in Chapter 5, the pressure of the wind on structures is proportional to the square of the wind speed. Thus, a 150 mph wind speed produces four times as much pressure as a 75 mph wind. However, wind speed, and thus wind pressure, varies over the different surfaces of a building.

Vertical axis wind generators are also being considered for the Freedom Tower that will be built on the former site of the World Trade Towers in New York City. The Freedom Tower is to rise 70 floors and be topped by wind turbines that designers predict will provide 20 percent of the building's electricity.

Pumping water and grinding grains can also be done using mechanical power from the turbine. As wind passes the turbines, it moves the blades which spin the shaft. Right now, there are currently two different kinds of wind turbines that are used. They are the HAWT (Horizontal Axis Wind Turbines) and the VAWT (Vertical Axis Wind Turbines).

Hills and valleys are land features that channel the wind direction and can increase wind speed at constriction points—for example, where a valley narrows and causes wind speed to increase due to a “funnel” effect. Forests and buildings are rough surfaces that increase turbulence in the wind field, causing greater vertical mixing.

Although wind often blows at a 90 degree angle relative to a vertical utility pole with a cylindrical surface, the wind angle is typically less than 90 degrees for most facilities attached to a utility pole, such as crossarms and conductors (which transfer their wind loads to the utility poles to which they are attached).

The wind turbine nacelle is designed to rotate on the top of its tower to get maximum wind potential. This system uses a little of the electricity generated by the turbine assembly. B Turbine Blades These aerodynamically designed blades are the length of two tractor trailers and catch the wind in such a way that the rotor assembly (the front ...

In California, several "wind farms" supply electricity to homes around Los Angeles. The propellors are large, to extract energy from the largest possible volume of air. The blades can be angled to "fine" or "coarse" pitch, to cope with varying wind speeds, and the generator and propellor can turn to face the wind wherever it comes from.
