Puhallinyksikkö

Puhallinyksikkö, also known as a wind turbine or wind generator, is a device that converts the kinetic energy from the wind into electrical energy. It consists of a rotor, which includes blades, a nacelle containing the generator and other components, and a tower that supports the rotor and nacelle. The rotor captures the wind's energy, which is then transferred to the generator via a shaft, producing electricity.

Wind turbines can be classified into two main types: horizontal-axis wind turbines (HAWTs) and vertical-axis wind turbines (VAWTs). HAWTs are the most common type, with blades that rotate around a horizontal axis. VAWTs, on the other hand, have blades that rotate around a vertical axis. Both types can be further categorized based on their size and power output, ranging from small-scale turbines used for residential purposes to large-scale turbines used in wind farms.

The efficiency of a wind turbine depends on several factors, including wind speed, turbine size, and blade design. Wind turbines are typically installed in areas with consistent and strong winds, such as coastal regions, open plains, and mountainous areas. They are a key component of renewable energy systems, contributing to the reduction of greenhouse gas emissions and the promotion of sustainable energy production.
