VAWT and HAWT Compared

Vertical axis wind turbines (VAWT) & horizontal axis wind turbines (HAWT) relative advantages:

VAWT HAWT
  • Non directional (can take advantage of wind blowing from any direction)
  • Generates  wind power when wind blows in the direction turbine blades are oriented
  • Less turbulence; particularly advantageous in metro areas
  • Works well at high elevation
  • Can be installed closer to allow more units in a smaller area
  • Works well in wide open areas
  • Lower start up speed generally
  • More recognizable because the giant visible turbines are HAWTs
  • Works well in both open and congested areas
  • Works with wind acceleration products
  • Tends to be less noisy
