Horizontal Axis
These turbines are the most common and normally
have three blades that are connected to the shaft.
These turbines also work well in open areas. The HAWT
are generally more efficient than the VAWT at high
speeds.

Vertical Axis
There are two types of vertical axis wind turbines, namely, the Savonius and the Darrieus.
Savonius wind turbines is one of the simplest wind turbines that consists of two or three “scoop”.
These turbines are less efficient than the HAWT. There are two basic types of Darrieus wind
turbines, that is, the “eggbeater” type and the H-rotor type.
Applications of Wind Energy.
The most common applications for wind systems are:
1. Standalone systems
Standalone systems are small wind energy systems best suited for isolated or rural areas
that are not connected to the electric grid. However, these systems can also be connected
to a mini, micro, or utility grid.
