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.
