Who knew Scottish wind turbines are kept warm with diesel power…

•, By Jo Nova

Since this was due to a cabling fault, presumably the other shivering wind turbines are maintained with mains power?

If giant turbine blades sit still too long, the bearings can generate permanent Brinelling damage. Alternately micro-oscillations or vibrations can cause False Brinelling. Small metal fragments then grind more of the metal around it, reduce efficiency, and increase the friction, the heat and the fire risk. It's a couple of the hidden costs of maintaining a vast network of infrastructure to collect low density energy. Coal turbines must be slowly rotated too, to avoid the shaft bending, but coal turbines run for months at a stretch without stopping. One coal turbine can weigh up to 600 tons, but wind turbines nacelles usually weigh 100-300 tons, but can weigh up to 700 tons)*. The largest wind turbine blades can weigh 35 tons each. The power-to-maintenance ratio of wind turbines is absurd.

The wind turbine industry today is like the jet engine industry of the 1950s. It will take decades of work to fine tune it and figure out true maintenance costs. The difference between jets and wind turbines is that in 1950 we knew we needed jets, but wind turbines are only useful in the fantasy land of junk climate models.

If ever there was proof that wind power is a national security issue, a rort, and a risk…
