The Simple Answer To Your Question; How Does Wind Energy Work...

Wind energy is fast gaining popularity as a clean and affordable source of energy. In order to understand what are the reasons of the success of wind energy, you have to first understand how does wind energy work. While it might be really hard for people to imagine that air can be used to generate energy, the fact is that it is successfully harnessed by the wind equipment to generate clean energy at very affordable prices. Let us see how it is done.

We know that when air moves at a fast pace, it becomes wind. Anything that moves has kinetic energy. The faster an object is moving, the more kinetic energy it has. The same kinetic energy is captured and turned into electric energy. The principle is roughly the same as is in the case of a hydroelectric power plant. The only difference is that instead of the moving water, we harness the kinetic energy of the wind. The main principle behind wind energy is that energy can not be destroyed, it merely changes form.

The windmill can be considered the mainstay of wind energy generation. It has specially crafted blades. These blades are designed to capture the kinetic energy of the wind and rotate. When the blade of windmill rotate they make the turbine which is connected by the wind mill to rotate along with themselves. The blades are connected to the turbine using a shaft. The movement of blades causes the shaft to spin. The shaft is in turn connected to the rotor of turbine. When the shaft spins the rotor spins with it and generates power.

The real source of wind energy is actually the sun. The sun provides heat to earth In case any are of the earth heats up, it also heats the air in contact with that land mass. Hot air being lighter tends to rise up. This displacement of hot air can take place very quickly. In order to ensure that a vacuum is not created when the hot air is displaced, the cooler air from surrounding areas tends to run in and fill the void at a rapid pace. This movement of cool air is what creates the wind that is the source of wind energy.

Naturally when you would place something in the way of wind, it would try to move that thing. In the case of wind energy, the blades of a wind mill are placed in the course of wind. The blades of a wind mill are fixed in such a manner that they rotate on an axis. Their rotation is what causes the transfer of kinetic energy to the mill and then to turbine.

Now that you are aware of how does wind energy work, you would be able to better appreciate the advantages of wind energy.
