Why this fear of high speed winds ? In the 1950s the French Compagnie industrielle des aéromoteurs (CIAMO) made a wind turbine made of flexible blades working even in a cyclone (90m/s). And I think they had 2 blades, as the protection came from flexibility.
From the paper published in the journal Proceedings of the Royal Society, it is clear that the use of flexible blades on wind turbines offers the advantage of increased versatility and efficiency. More research is required to discover optimal flexibility and to determine if such blades are commercially viable.
If wind speed it too high, they will stop them in order to avoid the damage. If spinning too fast, they can "explode" as illustrated at 1:25. Also, they might be used only to cover for the peak consumption period. When the consumption is low, some of wind turbines will be stopped (if the energy produced cannot be stored or sold).
because there is a direct relationship between the producer and the consumer. the supply and the load. instead of utilising methods of simply generating the maximum power from the wind and dumping it into a suitable storage media such as boiling water so we can drive steam turbines at a rate the load demands, we try to generate electricity directly from them on a demand only basis. and it doesnt work. that entire field of turbines designed simply to heat water, and absorb the energy in the wind at a rate proportional to the power contained therein, ie, cubed with velocity, would never have to be stopped... and would be running at maximum efficiency. you wouldnt need a braking system as the device producing the heat IS THE BRAKE. given a large enough thermal mass, a reservoir for all that heat, we can then bleed it off as required. how do we "bleed it off"? boil water, drive steam turbines. like we already are doing. but we no longer require the use of fuel or decomposing metals. IF it ever gets "too full"...so freaking what? it obviously needs a few more thousand cubic meters of storage volume! so thats why you see a field of them sitting there idle despite there being a literal gale blowing. because we are stupid. let all the power slip past instead of grabbing it. just as it starts actually producing any!
this is an interesting thing. as four just looks... stupid! i think of aircraft, and two is acceptable, three looks great, four looks like a toy, and anymore just looks... dumb. unless its a turboprop! or wheels... again, four never looks right, five is fine, six, seven, but never four! the few with four always look... wrong to me. cant explain.

What I want to know is why is it when I see a field with 100 windmills, only 30 are moving?

Probably need maintenance
That is a good question🙂 Why? :)
🥰
Aesthetics also... 3 blade turbines are better looking than 2 blade ones.
Yes
Doh
It's not meant to be beautiful, it's meant to be efficient !
