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. Furthermore, wind is a form of solar energy and is a result of the uneven heating of the atmosphere by the sun, the irregularities of the earth’s surface, and the rotation of the earth. Moreover, the terms wind energy or wind power describe the process by which the wind is used to generate mechanical power or electricity. Finally, wind turbines convert the kinetic energy of the wind into mechanical power. This mechanical power can be used for specific tasks (such as pumping water) or a generator can convert this mechanical power into electricity.

TYPES OF WIND TURBINES: Modern wind turbines fall into two basic groups: the horizontal-axis variety, as shown in the photo to the far right, and the vertical-axis design, like the eggbeater-style Darrieus model pictured to the immediate right, named after its French inventor. Horizontal-axis wind turbines typically either have two or three blades. These three-bladed wind turbines are operated “upwind,” with the blades facing into the wind.

Wind turbines can be built on land or offshore in large bodies of water like oceans and lakes.
SIZES OF WIND TURBINES: Utility-scale turbines range in size from 100 kilowatts to as large as several megawatts. Larger wind turbines are more cost effective and are grouped together into wind farms, which provide bulk power to the electrical grid. Single small turbines, below 100 kilowatts, are used for homes, telecommunications dishes, or water pumping. Small turbines are sometimes used in connection with diesel generators, batteries, and photovoltaic systems. 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.

A wind turbine works on a simple principle. This animation shows how 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. Wind turbines are mounted on a tower to capture the most energy. At 100 feet (30 meters) or more above ground, they can take advantage of faster and less turbulent wind. Wind turbines can be used to produce electricity for a single home or building, or they can be connected to an electricity grid (shown here) for more widespread electricity distribution.

The wind turbine working principle is followed by engineers when generating power through the forces of nature. For it to work most efficiently and increase the up time made during high velocity windy conditions, it is essential to install a strong framework that not only covers the essentials of power generation, but can also reduce the effect of damage in case of strong currents. Thus, there are certain guidelines that should be followed that are actually a formula of both the mechanics of the revolution process and the automatic reactions that are achieved through mechanical friction.
