The largest wind turbine currently in operation is the 6MW Enercon E-126, which has a rotor diameter of 126 meters (413 ft).

Basically, they have more torque which can be easier to convert into higher RPMs via some gearboxes. Smaller blades cannot push the gearboxes to as high speeds. Studies have shown that the larger blades, along with being cheaper per watt, also are way less likely to injure birds/wildlife. So, it's cheaper, and even more environmentally sound to use them where you can. Yes, at some point it would rock to be able to co-operatively own them, but the tech needs to be built up to the proper point before we can really get to doing that.

hope this isnt a dupe..

the amount of energy you can potentially extract

depends on the square of the length of the turbine

because the surface area it presents to the wind is Pi r *squared*

so doubling the length of a turbine quadruples the power etc

you get much more energy per metre of length

so bigger is always better

and as you say – a local community can pool resources and buy a big one
