1. Kinetic energy conversion

The generation of electricity from wind relies fundamentally on the principle of kinetic energy conversion. Wind, characterized by its mass and velocity, possesses kinetic energy. The function of a wind turbine is to capture this energy and transform it into mechanical energy, which is then converted into electrical energy. This process begins with the interaction of wind with the turbine blades, causing them to rotate. The rotational force, or torque, is transferred to a generator, which, through electromagnetic induction, produces electricity. The efficiency of this initial kinetic energy capture is a critical determinant of the overall performance of a wind turbine system.

The design of turbine blades plays a crucial role in optimizing kinetic energy conversion.
