Wind energy through a given cross section scales with the cube of air speed; kinetic energy per particle is proportional to the square of velocity, and mass flow is proportional to velocity. This makes high wind speeds difficult to design for, and most wind turbines will apply a brake and stop in high windspeed conditions in order to avoid overheating and other issues from the high energies involved.
