FINAL EXAMINATION (December-2015) (Total 40 pts @ 1pt/each)

1. Which one of the following statements is INcorrect?

a. Wind power availability in a given site and given height/speed increases linearly with the air density.

b. Typically large wind turbines (>1 MW) can produce power with incident wind velocities as low as 1 m/s.

c. The higher the height of the collocation of a wind turbine, the higher the power it can derive from the wind.

d. The wind shear index permits to determine the velocity of the wind at certain height, given the velocity at a

reference height.
