202 Types of Wind Turbines & Their Advantages

Traditional Vertical Axis Wind Turbines (VAWT) Vertical axis wind turbines, as shortened to VAWTs, have the main rotor shaft arranged vertically. The main advantage of this arrangement is that the wind turbine does not need to be pointed into the wind. This is an advantage on sites where the wind direction is highly variable or has turbulent winds.
