Up to 10 times more power from the latest generation wind turbines
It is difficult to dispute that the operational life of a current generation wind turbine has a predicted span of about 20 years, as compared to the 60 years claimed for a nuclear station turbine by Colin R McInnes (Letters, May 28).

This is largely attributable to perfectly well understood engineering practicalities. A nuclear station turbine functions in the benign environment of a generation hall and can be easily maintained on a regular basis. On the other hand, a wind turbine is exposed to harsh variable buffetings which limit turbine blade life due to fatigue and generator bearing life due to the stresses in the mechanical transmission linkages. Furthermore, maintenance, particularly for off-shore versions, is problematic.
