It's not even true when it's windy and sunny. Repair costs for those fucking eyesore windmills is so high, that the liberal retards ignore it to try and make wind look cheaper. In real terms wind is by far the worst possible means of power generation, even if you choose to ignore the unreliability.
We'd be better off burning wood than using windmills.
From what I recall from reading about domestic installations, the issue is the inverter, to flip the DC voltage from the panels over to mains AC. Solar might be economical for a while, but once the inverter needs replacement you're basically look at most of the cost of the system all over again.
Windmills could at least potentially use an AC generator, but I presume there's other electronics in there, as otherwise you're looking at some weird mechanical system to force a windmill generator to run at 50Hz, matching phase to the grid. So again, expensive electronics boxes.
And that's before we get to the issue that windmills are basically impossible to recycle. Those massive aerofoil blades are tough, to the point that while it's theoretically possible to recycle them, hardly anybody bothers.
They HAVE to be tough, to be able to stay intact at heavy winds and to be able to keep decapitating birds without suffering too much structural damage.
From what little I understand, it's actually largely just really stupid stuff like grit and dust eroding the aerodynamic surfaces of the blades. No one bit of grit does a huge amount of damage, but those things are out in the weather all day every day, and that takes it's toll...
In seriousness, yeah, I don't doubt it. A bit like how most of the wear that appears on ship propellers actually comes from air bubbles that they create. (Cavitation)
