VAWT’s have the turbine shaft running vertically to the ground. With this arrangement, the generator and/or gearbox can be placed at the bottom of the tower, near the ground. The tower doesn't need to support the turbine, and it doesn't need to be pointed into the wind. It is difficult to mount VAWT’s on towers, however. This means that they must operate in the slower, more turbulent wind near the ground, resulting in lower operational efficiency.
Used with wind generators, wind turbines have been used to generate electricity since the late 1800’s. Today’s modern wind turbines are highly-engineered, technically-advanced systems for producing clean, efficient, renewable electrical power.

why is it difficult to mount them on towers?
