6 FAQs about [Do wind turbines need wind ]

How do wind turbines work?

Wind turbines work on a simple principle: instead of using electricity to make wind—like a fan—wind turbines use wind to make electricity. Wind turns the propeller-like blades of a turbine around a rotor, which spins a generator, which creates electricity. To see how a wind turbine works, click on the image for a demonstration.

How does a wind turbine turn mechanical power into electricity?

This mechanical power can be used for specific tasks (such as grinding grain or pumping water) or a generator can convert this mechanical power into electricity. A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade.

Why does a wind turbine not produce power?

Below the cut-in wind speed, the turbine cannot produce power because the wind does not transmit enough energy to overcome the friction in the drivetrain. At the rated output wind speed, the turbine produces its peak power (its rated power). At the cut-out wind speed, the turbine must be stopped to prevent damage.

What is a wind turbine used for?

Wind turbines are the modern version of a windmill. Put simply, they use the power of the wind to create electricity. Large wind turbines are the most visible, but you can also buy a small wind turbine for individual use; for example to provide power to a caravan or boat. What is a wind farm? Wind farms are groups of wind turbines.

What is the difference between wind energy and wind power?

The terms "wind energy" and "wind power" both describe the process by which the wind is used to generate mechanical power or electricity. This mechanical power can be used for specific tasks (such as grinding grain or pumping water) or a generator can convert this mechanical power into electricity.

What is the difference between upwind and downwind turbines?

Upwind turbines—like the one shown here—face into the wind while downwind turbines face away. Most utility-scale land-based wind turbines are upwind turbines. The wind vane measures wind direction and communicates with the yaw drive to orient the turbine properly with respect to the wind.
