Vertical Axis Wind Turbines & Limits Of Innovation Vertical Axis Wind Turbines (VAWTs) have been around for a while but have found a recent popularity in the literature.  Traditional wind turbines are HAWTs or Horizontal Axis Wind Turbines.  VAWTs are an example of the kind of innovation that many people hope will help us to get to zero fossil fuel emissions by 2050. VAWT’s are cheaper to build than HAWTs but have more wear and tear (which means more maintenance), are closer to the ground where airspeeds are lower, and are less efficient than HAWTs (30% v 35%).  As a result, VAWTs have a lower ROI.  It seems likely that, until their ROI matches or exceeds the ROI of HAWTs, they will only be used in limited situations where conditions make them preferable to HAWTs.  These are for small energy applications where commercial electricity isn’t available and for densely populated areas where VAWT towers are not practical.
