What are the advantages and disadvantages of horizontal axis vs vertical axis wind turbines?
In research studies evaluating wind turbine performance, horizontal axis machines have been shown to be more efficient than vertical axis machines. However, the blade span of horizontal wind turbines is larger than vertical axis machines which limits placement confined spaces. Some people also find the large blade area of horizontal axis machines objectionable.
