Today electricity is a very big problem around the world, which leads to ecological imbalance as well. Therefore, another measure has been evolved to generate electricity with the help of renewable resources. Renewable resources have many advantages with it, but the major one is that it does not have any contribution to global warming and it is non pollution as well.

First use of energy is done through mills only. Windmills are having engines which are used to produce energy through wind. Today wind energy is used in large scale farms to provide electricity to rural areas and far-reaching locations. Wind energy is used in areas like Denmark, Germany and in areas of the United States. It is practical only at place where speed of wind is 10 mph.

Wind turbines are free to use as it use wind as a resource that is freely available everywhere. Wind turbines can be constructed anywhere, they do not emit greenhouse gases, but they are taller in size so an open and large field is required to construct them, but if offers again one advantage that the rest of the land can be used for farming as they do not produce poisonous gases.

Wind turbines available in a variety of sizes and types and can rotate either a horizontal or a vertical axis. Remote areas that are not easily connected into main power grids, can establish wind turbines, and thus create their own power.

Wind turbines are the rotary devices that are used to generate energy from the wind. Wind turbines works best in those location where the speed of the wind is high endlessly.

There are two types of wind turbine – horizontal axes and vertical axes; it can be rotate on both the axes. However, the most common and preferred type is horizontal axes. The above discussed characteristics are of horizontal type of wind turbine. The adaptable blade bump of the turbine blade assigns it an angle that it conclusive for hitting.

The high tower foundation of the turbine also allows access to the energetic winds with the aid of a wind shear. The effectiveness of these wind turbines is furthermore much higher because the blades consistently function in a direction that is perpendicular to that of the wind.

However a horizontal turbine has certain disadvantages along with many benefits. The blades and the tower for this type of wind turbine are so vast that moving them or shipping them becomes extreme hard or complicated. If one wishes to carry them it can be very expensive. Their hugeness also makes the installation of such wind turbines very difficult. Many preparations are mandatory to make this process on-going
