Wind farms are built after a rigorous analysis and planning process. In addition, depopulated areas are sought to avoid negative effects on inhabitants. The process involved in building a wind farm is very complex since there are many characteristics that must be analysed to know where and when it should be built.
Of these, the most important characteristics that must be analysed are the spatial, temporal and vertical variation of wind through time. These parameters are studied with wind vanes and anemometers and the future production of the wind farm is estimated to guarantee its potential efficiency. Cutting edge supercomputing techniques optimise the design of the wind farm complex to maximise the generation of energy. Sedar Project. Video voice transcription Spanish version [PDF]. Innovation is also allowing us to make great progress in offshore wind energy.
An example is the Romeo project , a European initiative led by Iberdrola to reduce the operating and maintenance costs of wind farms.
Iberdrola, pioneer in onshore wind power for 20 years, now stands out in offshore wind power with new projects and markets. Learn about Iberdrola's emblematic wind energy projects.

Carousel of images and videos. From there, the force of the air currents will set the three main parts of the wind turbine in motion: The rotor: composed of three blades and the bushing that joins them together, its function is to capture the force of the wind and convert it into mechanical rotational energy.
The multiplier: connected to the engine by means of a shaft, its function is to increase the rotational speed from 30 revolutions per minute rpm to rpm. The generator: this element is responsible for converting the mechanical energy of rotation into electrical energy.
The air that passes over the sweeping surface of the blades makes them turn. The resistance of the blades makes it lose speed. 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. Learn more about distributed wind from the Distributed Wind Animation or read about what the Wind Energy Technologies Office is doing to support the deployment of distributed wind systems for homes, businesses, farms, and community wind projects.

The Small Wind Guidebook helps homeowners, ranchers, and small businesses decide if wind energy can work for them. This video highlights the basic principles at work in wind turbines and illustrates how the various components work to capture and convert wind energy to electricity.

Wind is a form of solar energy caused by a combination of three concurrent events: The sun unevenly heating the atmosphere Irregularities of the earth's surface The rotation of the earth.
