-Verical Axis Wind Turbines or VAWTs offer a number of advantages over traditional horizontal-axis wind turbines (HAWTs). They can be packed closer together in wind farms, allowing more in a given space. This is not because they are smaller, but rather due to the slowing effect on the air that HAWTs have, forcing designers to separate them by ten times their width. VAWTs are rugged, quiet, omni-directional, and they do not create as much stress on the support structure. They do not require as much wind to generate power, thus allowing them to be closer to the ground. By being closer to the ground they are easily maintained and can be installed on chimneys and similar tall structures.
-In addition, by being closer to the ground VAWTs have the ability to take advantage of the tunnelling effects of small buildings and structures (provided the structures are build close enough) small VAWTs are also used in corners of buildings (usually the corner of a balcony).
-Although VAWTs are not considered as efficient as the more common HAWTs they are considers more reliable, and much easier to maintain.
