Wind has been used to do work since long time ago. The kinetic energy of the wind can be changed into other forms of energy, either mechanical energy or electrical energy. There are several examples of work done by the wind, including:
- Sail boats use the wind energy to push them through water
- Windmills have being used for centuries to pump water or to grind grains.
More recently, this wind energy has being used to generate electricity trough wind turbines. Wind turbines come in different sizes. Some of them are suitable for residential use allowing to create stand-alone applications to power individual homes. In utility-scale solutions larger wind turbines are frequently built close together in wind farms to generate enough electricity to supply the electricity needs of whole communities.
For individuals interested in solutions to power their home using wind energy, we suggest on checking some energy saving tips to use their electricity as efficiently as possible.
Wind energy has many practical applications besides generating electric power for individual and communities. Wind pumps are widely used to pump fresh water from wells and to help in pumping water into dry areas to aid in irrigation, for example, or to pump water out of flooded lands.
Wind turbines are turned by wind which drives a generator that, in turn, supplies the electric current. Wind usually needs to be at a minimum of 10 miles per hour for the wind turbines to work. The amount of electricity generated depends on many factors but it can be between 50 and 300 Kilowatts.
Wind turbines are most of the times mounted on high towers to take advantage of the faster winds that usually travel at higher heights and to avoid, as much as possible, the turbulent wind more characteristic of the air that is closer to the ground.
There are several varieties of wind turbines, including:
- Horizontal Axis Turbines (HAWT)
As their own name suggests the axis of this type of turbine is horizontal, or parallel to the flow of the wind. They usually have two or three blades and are the most frequently used wind turbines nowadays. A rotor converts the linear motion of the wind into rotational energy that is used to drive a generator.
- Vertical axis turbine (VAWT)
Vertical axis wind turbines have the axes of their rotor's rotation perpendicular to the wind stream and the to the ground. They are rarely used today.
The video below, published by the U.S. Department of Education, provides basic information about wind energy and its applications. You may also check on our energy glossary page for some basic concepts related to alternative energy sources.
