tuulegeneraator

A tuulegeneraator, or wind turbine, is a device that converts the kinetic energy of wind into mechanical energy that can then be used to produce electricity. These structures typically consist of a tower, a rotor with blades, and a generator. The wind causes the rotor blades to spin, which in turn drives a shaft connected to the generator. The generator then produces electrical current.

Tuulegeneraatorid are a renewable energy source, meaning they do not deplete finite resources like fossil fuels. They are a significant component of efforts to reduce greenhouse gas emissions and combat climate change. The electricity generated by wind turbines can be fed into the national grid or used for local power needs.

There are various types of wind turbines, including horizontal-axis wind turbines (HAWTs) and vertical-axis wind turbines (VAWTs). HAWTs are the most common, featuring blades that rotate around a horizontal axis parallel to the ground. VAWTs have blades that rotate around a vertical axis. The size of wind turbines can vary considerably, from small turbines used for individual homes to large, utility-scale turbines that form wind farms. The efficiency and effectiveness of a tuulegeneraator depend on factors such as wind speed, blade design, and turbine placement.
