How does wind power work?

Wind power has effectively been used for centuries to turn the power of a passing breeze into mechanical power. The early versions of wind power devices were simple windmills that were used for processing grain and pumping water. They worked by catching the power of the wind with a set of sails, and then converted this rotation of a central shaft into mechanical power for various activities. In some cases this wind mill energy was used for pumping water from a well for irrigation and other times it was used as the power for a mill. These early designs were very simple, but effective examples of windmill power and are still used today in a slightly more sophisticated form all over the world.

What started out as simple sail based windmills has matured into very sophisticated modern versions that are used for generating electricity for both commercial and residential customers. These modern versions are called wind turbine systems and are the result of decades of design and technological improvements in the area of wind power.

Several components make wind turbines generate an electrical current

The wind turbines contain several key components and each of these has been engineered for maximum efficiency. One of the main components is a set of rotor blades that are mounted to a housing designed to rotate around a central shaft as the blades catch the wind. Both the size and number of blades will determine how quickly the wind turbine rotates and how strong a wind it needs to operate. These blades can be made of various materials and most modern wind turbines use either a composite material or fiberglass blades because of their durability and light weight. This central rotating shaft is connected to a generator that will convert this rotation into electrical current.

The generator is very similar in design to a motor and consists of a series of magnets and coils that when turned, create an electrical current. This current can be either AC of DC and the generator is chosen based on the type and amount of current you want the wind turbine to generate. Most wind turbines generate a DC current that is either stored in a bank of batteries for use later, or converted to AC current through the use of an inverter.

Residential and commercial users benefit from wind power electricity

Wind power electricity has seen a resurgence in recent years both for residential and commercial use. Homeowners have taken advantage of newer, more efficient designs of smaller wind turbine systems that can be installed at their homes and used to generate power. They can then use this wind power electricity to lower their power bills each month and help the environment at the same time.

Commercial applications have expanded as well with several large wind farm projects being planned worldwide as a result of rising energy prices. Many power companies now view wind power systems as a viable alternative to other forms of power generation and have embraced the technology. As this field continues to mature, experts look for even more of a widespread adoption of wind power systems that are more efficient, quieter and less expensive.
