    Wind turbines: requirements and how they work

    Wind Power

    How Does it Work?

    Main components of a

    wind turbine

    Since wind speed increases with elevation above ground, wind turbines are installed on towers that are often as tall as a 20-storey building.

    Wind power is generated by the force wind exerts on the blades of a turbine, causing the turbine's shaft to rotate at a speed of 10 to 20 revolutions per minute (rpm). The rotor shaft is connected to a generator that converts mechanical energy into electrical energy.

    The amount of energy generated by a wind turbine depends on:

    wind speed (main factor)

    the area swept by the blades

    air density

    Wind turbines require:

    a minimum wind speed (generally 12-14 km/h) to begin turning and generate electricity

    strong winds (50-60 km/h) to generate at full capacity

    winds of less than 90 km/h; beyond that speed, the turbines must be stopped to avoid damage

    Correct option is A)

    Speed of the wind is an important element in rotating the turbines in the wind mills for the generation of electricity. Wind mills cannot be set up everywhere, it can be only set up in highly windy areas or with the minimum wind speed of 15 km/hr.
