A) Horizontal-axis wind turbines
B) Vertical-axis wind turbines
C) Multidirectional-axis wind turbines
D) Diagonal-axis wind turbines

Question

​_____ must face into the wind to produce power and, therefore, require some mechanism to constantly realign the rotor during changes in wind direction.
A) Horizontal-axis wind turbines
B) Vertical-axis wind turbines
C) ​Multidirectional-axis wind turbines
D) ​Diagonal-axis wind turbines

Quizplus · Accepted Answer

Horizontal-axis wind turbines must face into the wind to produce power and require some mechanism to constantly realign the rotor during changes in wind direction. Vertical-axis wind turbines can operate regardless of wind direction as they have blades that rotate around a vertical axis, but they are less efficient than horizontal-axis turbines. Multidirectional-axis and diagonal-axis wind turbines are not commonly used and do not have established track records.
