Wind turbines work on a simple principle: instead of using electricity to make wind—like a fan—wind turbines use wind to make electricity. Wind turns the propeller-like blades of a turbine around a rotor, which spins a generator, which creates electricity.

The basic idea is that wind turbines use blades to collect wind's potential and kinetic energy. Wind turns the blades, which spins a rotor that is connected to a generator to create electric energy. Most wind turbines have four basic parts: Blades are attached to a hub, which spins as the blades turn. The blades and hub together make the rotor.

How does a turbine generate electricity? A turbine, like the ones in a wind farm, is a machine that spins around in a moving fluid (liquid or gas) and catches some of the energy passing by.All sorts of machines use turbines, from jet engines to hydroelectric power plants and from diesel railroad locomotives to windmills.

In an ideal world, a turbine would convert 100 percent of wind passing through the blades into power. Because of factors such as friction, these machines only have efficiency ratings of between 30 percent and 50 percent of rated power output. Power output is calculated as follows: 00:03 12:50.

The generator turns that rotational energy into electricity. At its essence, generating electricity from the wind is all about transferring energy from one medium to another. Wind power all starts with the sun. When the sun heats up a certain area of land, the air around that land mass absorbs some of that heat.

A wind turbine works in the opposite way to an electric fan. Fans use electricity to make wind. Wind turbines use wind to make electricity. If you've ever flown a kite, you'll know the higher you go, the windier it is. That's why wind turbines are so tall – to capture more energy and generate more electricity.

So, when does a wind turbine work best? The power produced by a wind turbine depends on elevation, wind speed and air temperature. Wind turbines need wind speeds of at least 15 kilometers (9 miles) per hour, for small wind turbines, and 21 kilometers (14 miles) per hour, for utility-scale turbines.

HOW DOES WIND POWER WORK. CHARACTERISTICS. As we have already mentioned, in order to utilise the kinetic energy of the wind and convert it into electrical energy, it is necessary to use a wind turbine. The optimal use of these giants, (they are usually between 80 and 120 metres high) depends on the strength of the wind.

A wind turbine captures the wind, which then produces a renewable energy source. The wind makes the rotor spin; as the rotor spins, the movement of the blades drives a generator that creates energy. The motion of the blades turning is kinetic energy. It is this power that we convert into electricity.

Wind turbines generate electricity by using the natural power in the wind. A wind turbine's blades are like an aeroplane wing: as the air flows past the blade it causes lift, which creates a turning force. The rotating blades turn a shaft inside the nacelle, which goes into the gearbox. The gearbox increases that rotation speed for the ...

Because of these factors, wind energy is recognized as the world's fastest-growing new energy source. How does a Wind Turbine Work? Wind turbines operate on a simple principle. The energy in the wind turns two or three propeller-like blades around a rotor. The rotor is connected to the main shaft, which spins a generator to create electricity.

windmill, device for tapping the energy of the wind by means of sails mounted on a rotating shaft. The sails are mounted at an angle or are given a slight twist so that the force of wind against them is divided into two components, one of which, in the plane of the sails, imparts rotation.

The wind turbine model will do work on a small weight by hauling it up from the ground to the top of the turbine. This will represent the energy output of a wind turbine. You will measure the output of each rotor design by how much weight it can haul—the rotor that hauls the most weight is the most efficient design.

It works by pointing a device (usually 2 or 3 blades) into the wind and allowing the wind's energy to spin the blades. As the blades spin, the rotor they are attached to spin gears that are connected to an electrical generator. The gears speed up the spin rate from the slow moving blades to the fast moving generator engine.
