Plan for Progress  

A windmill is an equipment which utilizes the energy from the wind to produce other kinds of practical energy such as electricity. They are also commonly referred to as wind turbines specifically when referring to the kinds that are used to create electricity. When it comes to producing power, windmills are considered as highly dependable and useful. A windmill is comprised of a set of blades that are connected to a central axis that is designed to spin when it comes in contact with wind.

Windmills transpired from the need for creative and environmentally friendly method of utilizing energy. They have been in around from around the fifth century AD where they were being invented in Persia. The first forms were utilized as grinding mills but they have advanced tremendously over the years. The uses of windmills and the many different styles continue to change along with time and technology. This is apparent when you look at how they were maneuvered compared to how they are controlled these days. They once required the attention of someone continuously in order for them to function successfully. Nowadays, windmills are controlled by computers.

The use of windmills has widened to various countries as it is economical and it produces energy without releasing green house gases. Windmills use free energy to generate another kind of energy and that has resulted in the use of windmills to become accepted and common. They are also very attractive and in some countries they are seen as an attraction. In Holland and Spain for example, windmills form a part of their attraction. They have a wide variety of uses, some of which are:

1.Water pumping

2.Grain grinding

3.Generating electricity

How Do Windmills Work

The amount of power that is created by a windmill depends on several aspects. Firstly, its size is a major factor. The larger the sails are and the more blades included on the axis causes the generation of more energy. Secondly, its position or location. Windmills work properly in flat areas and they have to be used where there is wind to spin the blades. Finally, the amount of windmills that are used to generate power is important. The more windmills used, the more power will be created. On the other hand, one windmill can produce a significant amount of energy.

A wind mill is made up of various components so as to successfully generate energy. There are blades which are responsible for the majority of the work. These blades are attached to a body consisting of a very long pole. The height of the pole is important to the overall operation of the windmill since it raises the sails at higher elevation for improved access to wind. It is very crucial that a windmill is launched on a very strong and sturdy pole or tower as the stronger and higher they are, the better they function. Windmills are defined depending on the type of axis that they have. The most popular type is the horizontal axis which has three blades. The other type is those that have a vertical axis resembling an egg beater. This model has an advantage of operating effectively even when it is not facing the wind.

How a windmill works is straight forward. The sails are very essential in the production of energy since they do the majority of the work. The blades automatically spin when they come into contact with wind. This motion that is produced in turn produces energy which is then transferred from the blades through the shaft and then to the generator. When it reaches the generator, it converts the energy into electricity which has a benefit over other methods of electricity creation since it is pollution free.
