How Wind Power
Works
Humanity has relied on wind power for
Today, we use the wind for both recreational activities like windsurfing, and
practical applications such as the production of electricity. That’s right; an increasing number of people
worldwide are beginning to harness the wind’s energy in order to power their homes and businesses. Many industries
pry themselves on switching to this alternative source of power as well. So let’s take a look at how wind power
works. The flow of air that embodies the wind releases a kinetic energy while in motion. This energy can be converted into other types of energy, such as electricity. Wind patterns are widely influenced by the sun which represents another source of green power. Wind is caused in part by the sun’s irregular heating of the atmosphere, the rotation of the earth, and the irregularities of the earth’s surface. Water bodies, the earth’s terrain, and vegetation also play a part in influencing the patterns of the wind. “Wind Power” is a term which is usually employed to describe the process in which mechanical power or electricity is generated from wind. Wind turbines, wind energy converters, and generators are used for this exact purpose. Historically, the earlier models were simply referred to as windmills. #1 Best Selling, Step-By-Step Solar & Wind Power Guide On The Market Today
If you are wondering how wind power works, consider that the principal is basically the opposite of how a fan operates. A fan uses electricity to generate wind, as oppose to a wind turbine which uses wind to create electricity.
Wind Power Systems
Understanding how wind power systems function is the only point that you need to be familiar with, in order to understand how wind power works in general. A wind turbine (another term for a wind power generator or windmill) operates in the following manner.
Usually, each turbine comes with two to three blades which resemble a propeller. When flowing air comes in contact with the turbine’s blades, it makes them rotate.
The blades are attached to a shaft which spins as they rotate. There are two types of shafts: the high-speed kind and the low-speed kind. The shaft is connected to the power generator, which in turn generates electricity.
A controller is used to start and to shut off the machine. A brake deploys in case of very strong wind to prevent any damage to the assembly.
As you see, the basics behind how wind power works are quite simple.
Currently, there are two types of wind turbines that dominate the market: the
horizontal axis turbines and the vertical axis turbines. The horizontal axis variety, which is the most common, is
usually comprised of three blades operating “upwind” or facing into the wind. The vertical axis variety, which
resembles the shape of an eggbeater, can be pointed in any direction.
Large commercial wind turbines easily distribute power to the local grid if they are
connected to the central lines. These installations are also known as wind farms or wind power plants. In countries
like Spain and Denmark there are already many such wind farms powering entire towns. Other countries such as the
U.S, Brazil, South Africa, and Australia are constantly assessing how wind power works, in order to better
implement it in the future.
