Question

Wind turbines are classified into _____ general types.

• A. 2
• B. 3
• C. 4
• D. 5

Answer 1

The correct option is A 2

Wind turbines are classified into two general types: horizontal axis and vertical axis. Although vertical axis wind turbines have existed for centuries, they are not as common as their horizontal counterparts. The main reason for this is that they do not take advantage of the higher wind speeds at higher elevations above the ground as well as horizontal axis turbines.
