How Does Wind Generate Electricity?
Jun 04, · How wind turbines work. Wind turbines use blades to collect the wind’s kinetic energy. Wind flows over the blades creating lift (similar to the effect on airplane wings), which causes the blades to turn. The blades are connected to a drive shaft that turns an electric generator, which produces (generates) electricity. 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.
Wind turbines work on a simple principle: instead of using electricity to make wind—like a fan—wind turbines use wind to make electricity. How to generate electricity from wind turns the propeller-like blades of a turbine around a rotor, which spins a generator, which creates electricity. To see how a wind turbine works, click on the image for a demonstration.
Wind flow patterns and speeds vary greatly across the United States and are modified by bodies of water, vegetation, and differences in terrain. Humans use this wind flow, or motion energy, for many purposes: sailing, flying a kite, and even generating electricity.
The terms "wind energy" and "wind power" both describe the process by which the wind is used to generate mechanical power or electricity. This mechanical power can be used for specific tasks such as grinding grain or pumping water or a generator can convert this mechanical power into electricity. 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 how to do the hundred exercise lift and drag. The force of the lift is stronger than the drag and this causes the rotor to spin. This translation of aerodynamic force to rotation of a generator creates electricity. Most commonly, they have three blades and operate "upwind," with the turbine pivoting at the top of the tower so the blades face into the wind.
Vertical-axis wind turbines come in several varieties, including the eggbeater-style Darrieus model, named after its French inventor. Wind turbines can be built on land or offshore in large bodies of water like oceans and lakes.
The U. Department of Energy is currently funding projects to facilitate offshore wind deployment in U. Modern wind turbines can be categorized by where they are installed and how they are connected to the grid:.
Larger wind turbines are more cost effective and are grouped together into wind plants, which provide bulk power to the electrical grid. They do not have the same transportation challenges of land-based wind installations, as the large components can be transported on ships instead of on roads.
When wind turbines of any size are installed on the "customer" side of the electric meter, or are installed at or near the place where the energy they produce will be used, they're called "distributed wind.
Many turbines used in distributed applications are small wind turbines. Single small wind turbines—below kilowatts—are typically used for residential, agricultural, and small commercial and industrial applications.
Small turbines can be used in hybrid energy systems with other distributed energy resources, such as microgrids powered by diesel generators, batteries, and photovoltaics. These systems are called hybrid wind systems and are typically used in remote, off-grid locations where a connection to the utility grid is not available and are becoming more common in grid-connected applications for resiliency.

The wind direction is very crucial and must be determined before setting up the wind turbine Blades. Most wind turbines have about two or three blades installed in them. Once the wind .

According to the Department of Energy, wind turbines generate electricity when the wind moves the fan blades, which are connected to an electric generator via a central shaft. As the blades turn, they turn the generator, creating an electric current. The heart of a wind turbine is its generator, a machine that converts the rotational energy of the fan blades into electrical power.
It does so through the movement of conductive wire inside a magnetic field, with the wire loops or brushes connected to the central shaft of the turbine's propeller.
When the wind turns the blades at an appropriate speed, the moving wire becomes charged in the generator's magnetic field, producing an electric current. Turbines may be horizontal, in which case they look like giant pedestal fans, and often have the capacity to turn to follow the direction of the wind for maximum power production.
Vertical turbines look like eggbeater blades, and can function when the wind hits them from any direction. The electricity from wind farms flows only when the wind is blowing, which is why many regions of the country that have invested in wind power use it as a supplemental source along with conventional or other renewable methods of energy generation.
