Wind flows over the rotor of a wind turbine, causing it to rotate on a shaft. The resulting shaft power can be used for mechanical work, like pumping water, or to turn a generator to produce electrical power.
Wind turbines span a wide range of sizes, from small roof top turbines generating less than kilowatts up to large commercial wind turbines in the megawatt power range, many of which operate in large clusters called wind farms. The theoretical maximum efficiency of a wind turbine is given by the Betz Limit, and is around 59 percent.
Practically, wind turbines operate below the Betz Limit. The windmill has several models. We select the AMTL kw model. The windmill has basic simply configurations. It has tubular tower and also lattice. The parts are high speed generator, three stage gearbox, rotor and three blades. The top of the tower has the gearbox is fitted. The two sides of gearbox are one side is blade and other end has generator. The direction of wind flow has turned nacelle setup by the yaw drive system.
The wind velocity measurement, brake system and hydraulic unit are controlled by the electronic control unit. The yaw drive system is placed in that the vertically downward to the gearbox base plate.
The rotor blades are usually two or more in number and are made of Glass-fibre reinforced plastic or Epoxy resin laminated wood. It also includes structures of Aluminum Copper for lightning protection and steel for the connection to the hub. The hub in turn transfers the energy to the low speed shaft. Blade designs operate on either the principle of drag or lift. For the drag design, the wind pushes the blades out of the way.
The blades can be rotated by using either drag force or lift force. Drag powered wind turbines are characterized by slower rotational speeds and high torque capabilities. Blades come in many shapes and sizes, and there is continuing research into which design of blade is best. It turns out that the optimal design really depends on the application, or where and how the blade will be used.
This is the ratio between the speed of the wind and the speed the blade tip. Wind energy may be converted into mechanical and electrical energy. About 20, MW of electricity may be generated in India from wind. Winds have a high seasonal bias. They are much stronger during the monsoon than during the rest of the year.
The possibilities of predicting wingspread at a particular time of the year are rather poor. Location of wind farms on migratory routes could spell hazard to birds and disaster for some aviation populations.
Their appearance on the landscape and their continual whirring and whistling can be irritating. Preserve Articles is home of thousands of articles published and preserved by users like you.

By definition, renewable energy is energy generated from natural resources and is naturally replenished. This means that as long as the sun is available, winds will always blow.
Scientists project that the sun will continue to shine for the next billion years, which is a bright prospect for wind energy investors. Fossil fuels coal, oil, natural , on the other hand, are nonrenewable sources of energy because they are projected to deplete in the next 50 years or so.
On top of that, they cause a whole lot of pollution by emitting a wide array of greenhouse gasses. Wind energy is classified as a green source of energy since its production does not involve emission of dangerous fumes like fossil fuels.
This makes it a perfect energy source for the environment and humans. It all boils down to the number of turbines to be installed, the date the turbine purchase agreement was activated, cost of financing, location of the turbine installation project, construction contracts and much more. However, once these systems are up and running, the operational costs will significantly come down.
Only routine maintenance will be required to ensure the turbines are operating seamlessly. Over the years, households have entirely depended on traditional forms of electricity powered by fossil fuels. Investments in wind energy have helped bridge the power gap and helped dialed back on use of fossil fuels, which emit dangerous greenhouse gasses and cause global warming.
It could be an answer to the ever increasing demand for petroleum and gas products and would help us to reduce our reliance on fossil fuels from other countries. Generally, wind energy is space efficient. The largest wind turbines capable of catering to the electricity needs of about homes can be situated close together and the land in-between utilized for agricultural purposes.
This is the real reason numerous farms stand to benefit a great deal from installation of wind turbines rather than solar panels. Land owners can look for additional cash by installing wind turbines on land that can even be used for agricultural purposes. The electricity generated by wind power can be used for your own purpose which will reduce your monthly electricity bill and the surplus power can be sent back to the local grid which will result in more savings.
Moreover, you can check if your state government offers interest free loans or incentives on installation of wind turbines that will reduce the extra burden of initial investment on you. Although wind energy attributes to 2. Apart from this exponential growth rate lowering the potential of global warming, it helps bring down the cost of electricity.

Humans have used wind as a source of energy since the invention of sailing craft and windmills. And just as the wind has been harnessed to propel boats swiftly. Wind energy is an important non-conventional source of energy. There is a simple relation between wind, velocity and power. If a wind with a velocity of 10 km per hour gives one horse power, a 20 kmph wind will produce 8 hp. Winds with speed from 12 to 20 kmph capable of moving leaves and small.
