Real Engineering | The Problem with Wind Energy

Wind turbine service technician here, actually modern machines doesnt need to achieve 1500-1800 rpm to produce power, thanks to the converter system its possible to start producing usable power as low as around 900-1000 rpm (about 3.5 / 4 m/s of wind on 150m diameter machines at max blade pitch angle).

The way its done is simply to lower the voltage frequency on the generator side of the converters (while keeping 50/60Hz on the grid side).

The 1500-1800 range is now more of a "max power" range if the wind speed is high enough (4.2MW for a Vestas V150 MK3E for example, at about 11m/s).

About the maintenance on gearboxes in fact there is not really much to do most of the time, as soon as the service is correctly done (filter changes, oil levels) they can last more than the 7 years you are speaking without any issues. Of course gearboxes problems are possible, but they are pretty rare compared to the quantity of machines.
