Advantages : 

VAWTs offer a number of advantages over traditional horizontal-axis wind turbines (HAWTs):

  • they are omni-directional and do not need to track the wind. This means they don’t require a complex mechanism and motors to yaw the rotor and pitch the blades.
  • ability to take advantage of turbulent and gusty winds. Such winds are not harvested by HAWTs, and in fact cause accelerated fatigue for HAWTs.

As a major side-effect of urbanization, it is blamed for compromising health, disrupting ecosystems and spoiling aesthetic environments.To know more , click the given below link
