The blades move with the wind, generating a drag force which makes the rotor rotate. The size and shape of the blades may vary depending on the location and design of the windmill.

4. How wind energy is obtained in windmills

To understand, we must first understand how it works. These ingenious devices take advantage of the power of the wind to generate electricity in a renewable and sustainable way. In essence, windmills are ‌tall structures‌ with blades or ⁢blades that rotate ‌with the wind.

El process of obtaining wind energy In windmills it begins when the wind blows and moves the blades of the windmill. The wind exerts force on the blades, causing them to rotate. This rotation in turn activates a central shaft connected to a generator that produces electrical energy. The stronger the wind and the faster the blades spin, the greater the amount of electricity generated.

This rotational energy, in turn, drives an electrical generator that converts mechanical energy into electrical energy.

To achieve this transformation, the blades of the windmills are designed with an aerodynamic shape that makes the most of the kinetic energy of the wind. When the wind hits the blades, they begin to rotate thanks to the force generated by the pressure difference between the top and bottom of the blades. This rotational movement is transmitted through a shaft that connects the blades with the electrical generator, thus allowing the conversion of the kinetic energy of the wind into rotational energy and then into electrical energy.

The electrical generator of the windmills performs the final conversion of mechanical energy to electrical energy. This consists of a rotor that rotates thanks to the movement transmitted from the blades, as well as a stator that contains coils of wire. As the rotor rotates, a magnetic field is induced in the stator, generating electrical current in the coils. This current is finally transformed into usable electrical energy and distributed through a system of cables to the point of consumption.
