Dear Student
air is a fluid like any other except that its particles are in gas form instead of liquid. And when air moves quickly, in the form of wind, those particles are moving quickly. Motion means kinetic energy, which can be captured.
High-speed winds are used to do work on the blades of a turbine (at the so-called wind farm). The turbine blades are designed to capture the kinetic energy in wind. When the turbine blades capture wind energy and start moving, they spin a shaft that leads from the hub of the rotor to a generator. The generator turns that rotational energy into electricity.
Because the moving wind has mechanical energy (in the form of kinetic energy), it is able to do work on the blades.
Hope that satisfies your query.
