Which one among the following rotors is mostly used in wind turbines for electricity generation?

Correct option is B

Propeller rotors, also called horizontal-axis wind turbines (HAWTs), are the most commonly used rotor types in modern wind turbines. These rotors are highly efficient for converting wind energy into electricity. They consist of 2-3 long, thin blades that rotate around a horizontal axis. The design ensures maximum energy capture in a wide range of wind speeds, making them ideal for large-scale electricity generation.
Information Booster · Efficiency: The propeller rotor’s aerodynamic design minimizes drag and maximizes lift, enhancing power output.
· Usage: Widely deployed in onshore and offshore wind farms.
· Advancements: Modern designs often incorporate sensors and controls to adjust blade angles for optimal energy conversion.
Additional Knowledge · Multiblade Rotor: Typically used in applications requiring high torque but low speeds, such as water pumping.
· Savonious Rotor: A type of vertical-axis wind turbine, less efficient but useful in urban settings for small-scale power generation.
· Darrieus Rotor: Another vertical-axis design; it is aesthetically unique but less common due to operational challenges like low starting torque.
