HOW WIND TURBINES GENERATE ELECTRICITY
First, let’s answer a very important question.
What are Wind Turbines?
Wind turbines are devices that convert the wind’s kinetic energy into mechanical energy.
What are Wind Turbines?
If it further converts the mechanical energy to electricity, then we call it a wind generator.
Wind turbines have a variety of shapes and sizes…
But they’re all composed of the same 3 basic parts.

Now that you know its basic parts, let’s understand how
wind turbines generate electricity.

A. Capturing Wind Energy
Basic ProcessesA. Capturing Wind Energy
Basic ProcessesA. Capturing Wind Energy
Wind energy is captured using the wind turbine’s rotor blades.
Basic ProcessesA. Capturing Wind Energy
When wind passes through the blades, two aerodynamic forces are at work.
Basic ProcessesA. Capturing Wind Energy
LIFT
DRAG
Rotor Blade
Basic ProcessesA. Capturing Wind Energy
These two forces cause the rotor blades to turn, depending on how
much force the wind exerts on them.
Basic ProcessesA. Capturing Wind Energy
The process converts the wind’s kinetic energy to mechanical energy
(turning of rotor blades)
After this, it’s time to convert the mechanical energy into electricity.
Basic ProcessesB. Converting to Electricity
The turning of the rotor blades would simultaneously cause the shaft to turn,
which is connected to a generator.
Basic ProcessesB. Converting to Electricity
When the rotor blades

Basic ProcessesB. Converting to Electricity
In this process, the rotational mechanical energy of the shaft is
converted to electricity by the generator.
