Roofs need turbines.
Flat roof vents have no moving parts to break or squeak but don t vent as much air as wind driven vents.
Naturally the action of wind turbines depends on the wind.
Wind driven roof vents will pull more air from the attic but only when the wind is blowing.
When the wind blows regularly these vents can move more air than other types of vents but they are not effective when the air is still.
