Actually its both lubrication and hydraulic control issues.Its just lubrication and not a good preventive maintenance program.
The gear box on a 500kw GE unit holds 10-12 gallons of 45-60 oil. The hydraulic control systems (Brakes, blade turn, base turn, pitch and yaw control) hold upwards of 35 gallons of AW32 in them and the systems reservoir..
Most of what you see in the OP's pictures is hydraulic fluid leaking from control rams and the turret motor of the unit. Some of the newer units are using synthetics, which break down in sunlight to its base organic matter, the earth can deal with. Most of these wind turbines are not using the newer oils as they were designed for the fossil fuel types. The problem is the seals on the hydraulics, which these new oils simply eat holes in, as it is so costic. (acidic)
Even with the newer oils the areas directly below, in about a 200' radius, and down wind is laid waste in fairly short order if there is a leak. Throwing acidic substances, even if organic, on the landscape isn't good for it either but after about 3-5 years it will recover on its own as compared with oil which lays it waste for 20-30 years and poisons the water tables below as it leaches.
Wind mills have huge problems and destroy their environments, wildlife, and surface micro-cliamtes far worse than our gasoline vehicles and fossil fuel uses have done. The term "green" is far from the truth.. I doubt any of our enviro-nazis will look objectively at just how badly these things hurt the areas they are placed in.
Damn didn't know they were that sophisticated to have pitch and yaw, didn't even knew they turned, just figured they were stationary.
So again their preventive maintenance programs suck the big one.
