Wind turbine. A windMILL is a mill for grain that uses the wind to power it.

No. They don't.

Sorry, but that's just false.

A 2 MW wind turbine generates generates 2 MWh of electricity every hour 
the wind is blowing. It takes about 3,300 - 4,100 MWh of energy to build 
one.

So 1,650 - 2,050 hours of wind will pay that off.

A year has 8,766 hours.

Also false.

And you think they're impossible to cut into pieces?

"Could be"? You seem to object to the word "could" when others use it.

But for the record, there are something between 380,000 and 500,000 wind 
turbines in use worldwide. If the were all using the largest turbine 
blades currently made (Mingyang Smart Energy MySE 18.X-20MW) at 54 
metric tonnes...

...that would still only be 27 million metric tonnes.
