Understanding Wind Turbines Quiz

What is the primary function of a wind turbine?

• To generate electricity

• To pump water

• To grind grain

• To measure wind speed

Which component of the wind turbine captures the wind's energy?

• Tower

• Blades

• Nacelle

• Foundation

What role does the rotor play in a wind turbine?

• It supports the tower

• It converts wind energy into mechanical energy

• It stores electrical energy

• It measures wind direction

How is mechanical energy from the rotor converted into electrical energy?

• Through a generator

• Using a transformer

• Via a gearbox

• By the control system

What is the purpose of the nacelle in a wind turbine?

• To house the generator and other components

• To anchor the turbine to the ground

• To measure wind speed

• To support the blades

Why are wind turbines typically installed at higher elevations?

• To avoid obstacles

• To capture stronger and more consistent winds

• To be closer to power lines

• To reduce noise pollution

What is the function of the anemometer on a wind turbine?

• To measure wind speed

• To determine wind direction

• To control blade angle

• To monitor electrical output

How does the control system optimise a wind turbine's performance?

• By adjusting the blade angle and orientation

• By increasing the tower height

• By changing the blade length

• By altering the rotor size

What happens to excess electricity generated by wind turbines?

• It is stored in batteries

• It is fed into the power grid

• It is wasted

• It is used to power the turbine itself

What is one environmental benefit of using wind turbines for energy production?

• They produce no greenhouse gas emissions

• They require no maintenance

• They operate without any noise

• They can function in any weather condition
