A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade. When wind flows across the blade, the air pressure on one side of the blade decreases. The difference in air pressure across the two sides of the blade creates both lift and drag.

Step-by-step look at each piece of a wind turbine from diagram above: (1) Notice from the figure that the wind direction is blowing to the right and the nose of the wind turbine faces the wind. (2) The nose of the wind turbine is constructed with an aerodynamic design and faces the wind. (3) The blades of the wind turbine are attached to the ...
The huge rotor blades on the front of a wind turbine are the "turbine" part. The blades have a special curved shape, similar to the airfoil wings on a plane. When wind blows past a plane's wings, it moves them upward with a force we call lift; when it blows past a turbine's blades, it spins them around instead.
Wind Power Density (WPD) is a quantitative measure of wind energy available at any location. It is the mean annual power available per square meter of swept area of a turbine, and is calculated for different heights above ground. Calculation of wind power density includes the effect of wind velocity and air density.
Turbines catch the wind's energy with their propeller-like blades, which act much like an airplane wing. When the wind blows, a pocket of low-pressure air forms on one side of the blade. The low-pressure air pocket then pulls the blade toward it, causing the rotor to turn. This is called lift.
A wind turbine system is a complex structure that harnesses the power of wind to produce electricity. It consists of several components working together to convert the kinetic energy of wind into usable electrical power. Understanding the system diagram of a wind turbine is essential to comprehend its functioning and efficiency.
Each of these turbines consists of a set of blades, a box beside them called a nacelle and a shaft. The wind – even just a gentle breeze – makes the blades spin, creating kinetic energy. The blades rotating in this way then also make the shaft in the nacelle turn and a generator in the nacelle converts this kinetic energy into electrical ...
A wind turbine schematic diagram is a visual representation of the various components and systems that make up a wind turbine. It provides a clear and detailed overview of how the turbine operates and how different parts work together to harness the power of wind and generate electricity. The schematic diagram typically includes labels and ...
VIDEO. Energy 101: Wind Turbines. See how wind turbines generate clean electricity from the power of the wind. Highlighted are the various parts and mechanisms of a modern wind turbine.
The nacelle is the ‘head’ of the wind turbine, and it is mounted on top of the support tower. The rotor blade assembly is attached to the front of the nacelle. The nacelle of a standard 2MW onshore wind turbine assembly weighs approximately 72 tons. Housed inside the nacelle are five major components (see diagram): a. Gearbox assembly b.
Figure 4: Power flow diagram of a typical three-stage wind turbine gearbox. The low-speed input from the rotors (far left) is converted into high-speed torque at the output shaft (HSS) to feed the generator (top right). (Courtesy: Sentient Science Corp.) Some technical differences should be noted between land-based and offshore turbines.
The Power of Wind. Wind turbines harness the wind—a clean, free, and widely available renewable energy source—to generate electric power. The animation below is interactive. You can start and stop the turbine’s movement, hover over parts to see their description, and use the icons in the lower right corner of the animation to switch views.
A wind turbine, or wind generator or wind turbine generator, is a device that converts the kinetic energy of wind (a natural and renewable source) into electricity. Whereas a ventilator or fan uses electricity to create wind, a wind turbine does the opposite: it harnesses the wind to make electricity. And, the taller the turbine, the stronger ...
However, the term wind turbine is widely used in mainstream references to renewable energy (see also wind power). Types. There are two primary types of wind turbines used in implementation of wind energy systems: horizontal-axis wind turbines (HAWTs) and vertical-axis wind turbines (VAWTs). HAWTs are the most commonly used type, and each ...
Total annual U.S. electricity generation from wind energy increased from about 6 billion kilowatthours (kWh) in 2000 to about 434 billion kWh in 2022. In 2022, wind turbines were the source of about 10.3% of total U.S. utility-scale electricity generation. Utility scale includes facilities with at least one megawatt (1,000 kilowatts) of ...
