Explain how a wind turbine uses wind energy to generate electricity, mentioning two energy conversion steps.

Wind energy is the kinetic energy of moving air. A turbine blades capture that wind and cause the rotor to turn, so the wind’s kinetic energy becomes rotational mechanical energy. The rotor drives a generator, and as it spins, the generator converts that rotational mechanical energy into electrical energy. So the two energy conversion steps are: wind kinetic energy to rotational mechanical energy, and rotational mechanical energy to electrical energy. The wind isn’t being stored as chemical energy, nor is the process primarily about heating or just converting to potential energy.
