Wind Energy: A Natural Source
Nature is the ultimate source of energy. Everything we use in the name of energy comes from nature and its resources. Wind is an energy converted form of solar energy. This kinetic energy is linked with the changing moves of atmospheric air. For hundreds of years, wind energy has been used for various purposes, such as sailing, grinding grain and for irrigation. Wind energy systems have the capacity to translate this kinetic energy to more effective power forms. The rays of sun touch different parts of the earth at different levels during the day and night. Therefore, the different surfaces, such as water and land, absorb or reflect heat at different levels and at different time. As a result of which, different portions of the earth get warmed differently. By reducing the atmospheric pressure at the earth’s surface hot air increases and cool air is drawn in to replace it and thus, wind is created.
In very simple language, wind power is nothing but the translation of wind energy into an effective form of energy. For example wind turbines for making electricity, wind mills for mechanical power, wind pumps for pumping water or drainage, or sails to propel ships etc. Generally, in order to provide electricity to distant places smaller wind farms are used and the big scale wind farms are joined to the electric power transmission network. Wind energy is power source which is bountiful, renewable, distributed widely, fresh, and creates no greenhouse gas emissions during the operation and therefore, is considered as a useful substitute to fossil fuels. However, due to their visual influence and other effects on the environment, the creation of wind farms is not generally appreciated.
In order to produce electricity, wind energy is very essential. Wind power is usually non-dispatchable, that means it is for cost-effective function. All of the obtainable output must be taken when it is accessible to match the supply with demand. However, for other kinds of resources, the techniques such as: hydropower and standard load management techniques must be used. When using wind power to provide a low percentage of total demand, the intermittency of wind rarely creates any issues, but the prices and the costs increase with the proportion rise.
For the purpose of irrigation and milling, wind energy systems have been in use since a long period of time. In the beginning of the 20th century, in order to produce electric power, wind energy systems are used. In many countries, especially in the rural areas Windmills for water pumping have been installed.
The most cost-effective use of wind electric turbines is in collection of large machines which is called as wind power plants or wind farms. Generally, in the wind farms, the individual tribunes connected with each other with a medium voltage power collection system and communications network. Then, at a substation, in order to connect with the high voltage electric power transmission system, the voltage of the medium-voltage electrical current is increased with a transformer. In some jurisdictions, the extra power generated by domestic micro generators are supplied into the network and sold to the value company that creates a retail credit for micro generators’ owners to reimburse their energy costs.












It is also important to know the basic elements for positioning a wind turbine (e.g. tower height, safety precautions).

Great article! I am going to send this out to my followers on twitter, I think that they will enjoy it as well.
Would you be interested in doing a feature post for me? Let me know.
I like how you went into the history of the wind turbines. enjoyed the post and am looking forward to coming back more often…
