A wind turbine extracts energy from moving air.  
The wind turns large blades connected to a rotor.  
This rotor spins a shaft inside the turbine.  
The shaft is connected to a generator.  
As the shaft rotates, magnets spin around coils of wire.  
This produces an electric current through induction.  
The electricity can then be sent to the grid.  
Modern turbines use sensors to face the wind correctly.  
They adjust blade angles for maximum efficiency.  
Wind turbines help generate renewable, clean energy.  
They are commonly found in wind farms on land and sea.
