Is bigger better when it comes to wind power?

[rrrrrrrrrrrryan]

Yes, for two reasons: windspeed is greater at higher altitudes, and energy capture increases with the square of the blade length:

This means that a windmill constructed with 3x the building material (3x blade diameter and 3x taller) will generate over 9x the power.

Windmill efficiency scales faster than (blade length)^2, so yes.
