What is VAWT considering the wind turbine?

The correct answer is option 2):(Vertical Axis Wind Turbines)

Concept:

• Vertical axis wind turbines (or VAWTs) have the main rotor shaft arranged vertically.
• Key advantages of this arrangement are that the turbine does not need to be pointed into the wind to be effective.
• This is an advantage on sites where the wind direction is highly variable.
• They  produce electricity by utilizing wind power the same way horizontal axis wind turbines do. Wind drives the rotor to turn, the rotation connects to the generator, and the generator converts the mechanical energy into electricity.
