The installation of a home wind turbine is not considered very cheap; however, it turns out a huge money saver in the long run when the cost of producing power becomes zero. It has been observed lately that people are implementing wind power solutions even at places with the average speed of power less than 11 miles per hour. Ideally, the average speed of wind at the site you propose to set up the home wind turbine at should be 11 miles per hour, but a slightly lower average is also reaping good results for people. 

One thing that dissuades people from setting up a home wind turbine is the initial cost. However, one can set up a wind turbine at home at a much less price. It is, however, important to consider certain things while setting up it up on your own.

• Get a good plan to make a home wind turbine at home. Keep in mind the output you want the wind turbine to generate.

• Look for sturdy components. Your home wind turbine should not get damaged by heavy winds.

• Compare the prices of the equipment in the market and go for the components that suit your budget and your site.

When looking for a home wind turbine plan, look for the following features:

• Illustrations: Visual descriptions work better than only-text ones. If your wind turbine guide has illustrative descriptions for making a windmill, it makes your task easier.

• Easy language: If your guide uses a lot of jargon and technical information, it is better to look for a different one. Look for one that has easy-to-understand language making your task fluid.

• Component descriptions: Your guide should be able to provide you with detailed visual and textual descriptions of all the components you need to use. It is also important that the guide tells you which type of component works best for a site like yours.

• Local information: If your guide gives you information about the best available equipment in Europe while you are reading it from a countryside location in western USA, your guide is as good as useless. Look for a guide that provides equipment information of places around you.

 What is a wind turbine?
A wind turbine is a system which transforms the kinetic energy available in the wind into mechanical or electrical energy that can be harnessed for any required applications. Mechanical energy is most commonly used for pumping water. Wind electric turbines generate electricity that can be utilized locally or transported to the desired location through grid.

What are the different configurations of Wind Turbines?
There are two basic configurations of Wind Turbines. One is Vertical axis wind turbine and the other is Horizontal axis wind turbine. The horizontal axis turbine has seen technological and economical growth and it has become the commonly used commercial turbines on large scale and the vertical axis turbines are still in the demonstration purpose and small scale applications.

How much power can a wind turbine generate?
The ability of a turbine to generate electric power is measured in Watts (The rate of energy transfer equivalent to 1 Ampere of electric current flowing under a pressure of 1 Volt at unity power factor). Watts being a small unit of power, kilowatts (kW = 1000 Watts) and Mega Watts (MW = 1 million Watts) are the most commonly used units to describe the generating capacity of wind turbines and any power generating unit in
general. Electricity production and consumption are most commonly measured in kilowatthours (kWh). A kilowatt-hour means one kilowatt (1,000 Watts) of electricity produced or utilized in an hour (To light up a 100 Watts bulb for 10 hours requires 1 Kilowatt-hour of electricity). Watt-hour is the electrical energy unit of measure equal to 1 Watt of power supplied to, or taken from, an electric circuit steadily for 1 hour.
The power produced by a wind turbine depends on the turbine’s size and the wind speed through the rotor. In India, we have the commercial large wind turbines from 225 kW to 2.5 MW. In the global market, 6 MW wind turbines are operating and turbines of 10 MW are in laboratory stage.
Wind speed and a wind turbine size are the factors that determine the power generation capacity of a wind turbine installation. Usually, wind resource assessment is done prior to a wind system’s construction. It can be noted that the power generated is cube of the wind velocity and because of this, even a small difference in wind speed will bring about a large difference in available energy and in electricity produced and therefore, a large difference in the cost of electricity generated.
What will be the power generation in a 100kW wind turbine?

A 100 kW wind turbine produces 100 kWh or units of electricity after running for an
hour, at its rated wind speed of about 12 – 14 m/s. Likewise, a 250kW turbine at its
rated wind speed of about 12m/s produces 250 kWh after 1 hour of operation.

Does wind turbines height affect the generation?
Yes, to achieve more power generation, the turbine should require more wind
speeds with velocity, which will be available in a good elevation. If the rotor is placed
at a height where the flow is least obstructed by obstacles and as the height
increases the wind faces less friction from its nearest surface.
Will a wind turbine produce power in the rain season?
Yes, but the generation will be less when the air is humid and has larger percentage
of water molecules. if the air is dry and has no water molecules, a wind turbine will
produce more power.
What is the life of a Wind Turbine?
Generally, the present wind turbines are designed to last for a period of 20 years. It
can also be designed for more than 20 years, only thing is the machine will be far
more bulky and costlier than what is available now and would be prohibitive as a
alternative to explore economically.
What happens when the winds become too much for the wind turbines?
When the wind speed is high beyond cut-out speed, the turbine stops producing
power and goes into an inert state to avoid components’ stress and damages.
Normally the machines are manufactured with safety incorporation to cater to most
of the conceivable emergencies.
Can we mount a small wind turbine on our roof top?
Yes, small wind turbines are mountable on roof top for domestic applications. Right
now, in India, mostly small wind turbines are stand alone which stores power in
battery and in some of the western countries even small wind turbines are connected
to the local grid. Small wind turbine with capacity ranging from 300 W to 25 kW are
now available in Indian market and gaining popularity.19.What is a wind farm?
The most economical application of wind turbines is in groups of large machines.
They are called ‘Wind farms’ or’ wind power plants’. Wind plants can vary in size
from a few Mega Watts to hundreds of Mega Watts in capacity.
Where does the power generated from a wind turbine go?
Normally, the powers produced by large wind turbines are connected to the state /
central electricity grid whereas smaller wind turbines normally charged into a battery.
Now a day lots of encouragement steps are being initiated to couple small wind
turbine into grid. The power concentrated to the grid can be sold to the state utility /
any private party / can also be used for captive use by paying wheeling charges
alone.
Can a wind turbine be mounted on a moving structure and be used to
produce power like on trains, buses etc?
It is not a economically feasible idea to produce power from a moving platform
because the resistance generated to the advancement of the moving platform due to
the wind turbine would have to be overcome by consumption of more power than
that the wind turbine mounted on its top would produce. Hence the net power
produced from the adventure would be in the negative domain.
