Wind Turbine Parts

 Wind energy has always played an important role in technology, originating in Egyptians sailboats and Persian windmills, to the wind turbines we know today.

At the start of the decade, wind energy accounted for zero per cent of the UK’s energy. Over the years this steadily increased as we became more environmentally conscious, resulting in wind supplying almost three per cent of the total energy production at the end of 2018.

The makeup of a wind turbine can range depending on the maximum output, but each usually consist of four main wind turbine parts:

Generator (Nacelle)

Using electromagnetic induction, generators produce an electrical voltage (or electrical pressure) – a force that moves electricity from one point to another. A simple generator consists of two parts – a conductor (typically a coiled wire) and magnets that surround the conductor. Voltage is produced when either the magnets or conductor begin rotating relative to the other – in this case, when wind turns the rotor blades.

This voltage then drives electrical current (usually an alternating current) through the power lines for distribution. A wind turbine slip ring will then transfer this electrical current from the rotating unit, through the stationary parts of the turbine (the tower and foundation).

Rotor blades

The blades of a turbine act as barriers against the wind. When the wind hits the blades, it forces them to turn and activate the generator, transferring the wind force into electricity. Some turbines also have a built-in system that adjusts the angle of the blades to control energy output, which is especially important for high wind speeds.


A tower’s height is crucial for turbines because wind speed increases with height. This is why most turbines are created to reach heights between 50 and 150 meters tall, where wind is high, but the load stays low due to turbulence.


The foundation connects the tower to the ground and bears the static and dynamic loads created by the turbine. Usually, a foundation is created from a mix of steel mesh and concrete to root the turbine into the ground for higher stability.
