  1. Wind Speed

  2. Rotor Diameter

  3. Air Density

  4. Turbine Height
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Wind speed has the most significant impact on power output, as higher wind speeds generate more kinetic energy.

Multiple choice

Which type of wind turbine is commonly used in offshore wind farms?

  1. Horizontal Axis Wind Turbine (HAWT)

  2. Vertical Axis Wind Turbine (VAWT)

  3. Darrieus Wind Turbine

  4. Savonius Wind Turbine
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Horizontal Axis Wind Turbines (HAWTs) are the most common type used in offshore wind farms due to their higher efficiency and power output.

Multiple choice

Which type of wind turbine is known for its vertical axis of rotation?

  1. Horizontal Axis Wind Turbine (HAWT)

  2. Vertical Axis Wind Turbine (VAWT)

  3. Darrieus Wind Turbine

  4. Savonius Wind Turbine
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Vertical Axis Wind Turbines (VAWTs) have a vertical axis of rotation, making them less sensitive to wind direction changes.
