Caring for the environment has become a national concern and people at all levels should work towards it. Along with saving energy in households, it is necessary that the commercial set ups of also lend their hands towards this social responsibility. The use of wind turbines has helped many commercial set ups to save energy, money and uplift their social images.

It is becoming essential that the businesses choose the right kind of energy source since the energy costs are sky rocketing. Taking advantage of the renewable source of energy has enabled several companies to save huge amount of money as well as lessen the adverse impact on the environment. Here are a few ways how wind turbines can help businesses and factories:

1. Create a Bright Future: The government is encouraging various businesses to install renewable energy equipment in their workplaces, so that energy can be saved. Small businesses and individuals producing small-scale energy for their own needs helps to compensate the huge amount of energy that is require for retail parks, supermarkets, etc.
2. Adopt Renewable Energy Sources: The dependency on traditional forms of energy can be reduced only by using alternate forms of energy. Wind turbines, that use wind energy for producing electricity, are the best alternative power sources for factories and businesses. The use of wind turbines is handy because wind turbine control systems, electric generator for wind turbine and other essential components are easily available.
3. Portray a Positive Business Image: With everyone going green, it is very important for businesses and commercial set-ups to act responsible. Installing wind turbines and other renewable energy equipments in the workplace and factories will give out a positive message and hence it will also help in uplifting your brand image.

Benefits Of Using Wind Turbines For Businesses

• Works efficiently without causing pollution.
• Wind power is the most reliable source of renewable energy and we’ll never run out of it.
• Wind turbines are very space-efficient.
• The popularity of electricity produced from wind power is growing at a fast pace and it is the way everything will be tomorrow.
• The cost of producing electricity with help of wind turbines has reduced incredibly and is expected to decrease further, making it more effective and efficient for businesses.
• The operational costs are also very low

So there are more than one ways in which businesses can benefit from wind turbines. More and more businesses and factories are using renewable form of energy to build a sustainable environment and it is expected even more people will join hands.

Wind turbines have been used for centuries to generate electricity that can be used for various applications in households as well as for commercial uses. Wind turbines use the kinetic energy of the wind and convert it into electrical energy. Large wind turbines have propellers connected to generators, which when moved by the wind generates electricity. Individual wind turbines can also be used for producing electricity on small scale to support a single home. Whereas large scale electrical energy can be produced with the help of a group of wind turbines, known as wind park or wind farm.

The blowing wind moves the blades while passing through the turbines and this result in spinning of the shaft. Two types of wind turbines can be used to produce electricity namely, Vertical Axis Wind Turbines (VAWT) and Horizontal Axis Wind Turbines (HAWT). The most commonly used wind turbines are the HAWTs and they have fan-style blades, whereas the VAWTs have egg-beater style blades.

How is electricity produced in Wind Turbines?

Before you start looking up for wind turbines for sale, you need to understand the working principle of turbines, so that you get the best one for your use. Here is how electricity is produced by wind turbines:

• • Each wind turbine is fitted with box on top which is known as nacelle. Three blades are attached to this nacelle and they are also connected to a rotor. The anemometer on the nacelle measures the wind speed and wind direction.
  • The nacelle is turned towards the wind and the kinetic energy of wind turns the blades around the rotor.
  • The rotor is connected to the shaft that rotates inside generator housing. This results in the magnetic rotor to spin inside loops of copper wire. This activates the electrons inside the copper wire to flow, producing electrical energy.
  • Thus electricity is then routed to the underground cable through large cables that are attached to the nacelle.

At wind parks, electricity from various turbines is directed to the substation where a step-up transformer increases the electrical output.

How are the blades connected to the shaft?

The blades turned by the wind results in formation of electricity and there are two ways in which the blades are designed, namely lift type and drag type.

1. Lift Type: The most commonly used HAWT use this design. The air blows across both sides of the blade which means that the air takes longer to travel across the edge. As a result of this high pressure is created on the tail edge and low pressure is created on the leading edge. This pressure difference make the blades to move at a high rotational speed which is requires to generate electricity.

2. Drag Type: The force of wind is used to move the blades and they have higher torque compared to lift designs but with lower rotation speed. This type of design cannot be used for large scale energy generation since it has low rotating speed.

It is essential to produce green energy to save the earth and create a sustainable environment. The most commonly used renewable source of energy to produce electricity is Wind that can be found in ample amounts all the time. But at times it becomes very unreliable and unpredictable because of the fact that it constantly changes its strength and direction.

Why Wind Turbine are Made Tall?

To utilize it wind power and produce maximum amount of energy, wind turbines are made tall and large. For wind turbines to be functional they need to be designed and engineered very well and this is the reason why they are so expensive. Most of the modern day wind turbines are provided with two to three blade propellers that rotate around a horizontal axis. These wind turbine blades convert the wind energy into shaft power known as Torque, which is produced as a result of the deceleration of wind blowing over the wind turbine blades, with help of various techniques.

So Why Are The Wind Turbine Blades Twisted Or Curved?

A lifting force is generated due to the curved shape of the blades just as in case of an aeroplane wing. A low air pressure is created on the side with most curve, while the high pressure created beneath pushes the other side of blade aerofoil. This results in generation of a lift force that is perpendicular to the air flow direction. The rotor blade also needs to be designed appropriately to generate the right amount of rotor blade thrust and lift to produce the exact amount of deceleration of air.

What is TSR and what factor it Depends?

The wind turbine blades have to rotate at an optimal speed to extract the maximum amount of energy. If it rotates slowly, it won’t be able to produce enough energy and if it rotates quickly it will create excess drag. The tip speed ratio (TSR) is the ratio between the speeds of the rotor tip to that of the wind speed. The TSR depends on the number of turbine blades, rotor blade shape and the shape of the wind turbine blades.

Wind Turbine Generate Power at Low Costs

The wind turbine blade cost is higher since it needs to be designed in a manner that it maximizes the power generation at low costs. The turbine blade manufacturers constantly work towards improving the design of the blades so that they can be quieter, compact and capable of generating maximum power from minimum wind.

Twisting the blades of the wind turbine makes it capable of capturing 5-10% more energy from wind and functions efficiently in places that have lower wind speeds.
