Modern wind turbines contain moving parts (e.g. in the gearbox) that require lubrication to protect them from premature wear and achieve optimal performance.
Oil condition is checked as part of the regular servicing regime to maintain performance. Any oil that is replaced is then recycled or disposed of responsibly.
The amount of oil used by a turbine varies greatly depending on the size and type of turbine.
