The mechanics and workings of wind turbines How long do wind turbines last?
A wind turbine typically lasts around 20-25 years. During this time, as with a car, some parts may need replacing. At the end of their lives, they can be decommissioned within a couple of days and replaced with newer designs.
The very first of the mass-produced turbines celebrated its 20th birthday in May 2000. The Vestas 30kW machine has operated steadily throughout its lifetime, and so far, none of the major components have had to be replaced.
