There are two different types of wind turbine
; Vertical and Horizontal. Each one performs their own function and they each of their advantages and their disadvantages. You should pick the one that is best for you and your needs. They do have one thing in common and that is that they produce energy from winds. They just do it in a different way.
Vertical axis turbine
has the main rotor shaft running vertically instead of horizontally. This direction can have its advantages and disadvantages. The advantage is the gearbox can be put in the bottom of the turbine, unlike the horizontal turbines. All the weight is not at the top of the tower.

is a rotating machine that seeks to convert the kinetic energy present in the wind into mechanical energy. If particular machinery like a pump or 
uses the mechanical energy in a direct manner then it is called a 
, however, if this mechanical energy is first converted into electricity and then used, then the machine is commonly called a 
or a wind energy converter amongst other things.
were used in Persia, as far back as 200 B.C for the purposes of 
. By 250 A.D the Romans began to use the same process for the same purpose. The Dutch started using 
to drain water from the areas lying in the Rhine River delta.
