Vertical-axis wind turbines: what makes them better ...

While most wind turbines are configured for rotating about a horizontal axis, a relatively newer type of wind turbine- known as a vertical-axis wind turbine ("VAWT") – is configured for rotating about a vertical axis. One advantage of this arrangement is that the wind turbine does not need to be pointed into the wind to be effective ...

Vertical Axis Wind Turbines Advantages & Disadvantages

The vertical design allows engineers to place the turbines closer together. Groups of them don't have to be spaced far apart, so a wind farm does not have to take up as much ground area. The proximity of horizontal wind turbines to one another can create turbulence and reductions in wind speed that affects the output of neighboring units.
