Not sure I'd take too much notice of a website dedicated to the problems of a system.
You're not going to get any balance there...
In general I'd agree with you, Pete, but details regarding turbine failures are indisputable, surely, and verifiable?
Like
here which claims to be based on definitive data.
Or this extract from an IEEE survey into reliability and failure
ABSTRACT
The wind power industry has expanded greatly during the past few years, has served a growing market, and has spawned the development of larger wind turbines. Different designs and technical advances now make it possible to erect wind turbines offshore. The fast expansion of the wind power market faces some problems. The new designs are not always fully tested, and the designed 20-year lifetime is typically never achieved before the next generation of turbines are erected. This paper presents results from an investigation of failure statistics from four sources, i.e., two separate sources from Sweden, one from Finland, and one from Germany. Statistics reveal reliability performance of the different components within the wind turbine. The gearbox is the most critical, because downtime per failure is high compared to the other components. The statistical data for larger turbines also show
trends toward higher, ever-increasing failure frequency when compared to small turbines, which have a decreasing failure rate over the operational years
And then there is
this academic paper.
Strewth..I didn't realise just how unreliable the damn things are!
