What is the role of wind energy?

Some points on role of wind energy are:

• Wind energy captures airflow using aerodynamically shaped blades that extract kinetic energy from moving air streams.
• The angle and shape of turbine blades create lift forces that initiate and sustain rotational motion.
• Mechanical energy produced by blade rotation is transferred through a drivetrain to the generator input shaft.
