Do wind turbines use electricity to start turning?

Wind turbines do not use electricity to start turning. Instead, they rely on the force of the wind to get their blades moving. The blades are designed to catch the wind and convert its kinetic energy into mechanical energy, which is then used to generate electricity.

The process of starting a wind turbine is called yawing. Yawing involves turning the turbine's nacelle, which houses the generator and other electrical components, to face the wind. This allows the blades to catch the wind and start turning.

Once the blades are turning, the wind turbine's generator converts the mechanical energy into electricity. The electricity is then sent to a transformer, which increases the voltage so that it can be transmitted to homes and businesses.

Wind turbines are a clean and renewable source of energy. They do not produce any emissions, and they can help to reduce our reliance on fossil fuels.
