What type of energy transformation occurs in a wind turbine?

In a wind turbine, the primary type of energy transformation that takes place is from wind energy to mechanical energy. As wind passes over the blades of the turbine, it causes them to rotate. This rotational motion represents the conversion of the kinetic energy of the moving air (wind energy) into mechanical energy, which can then be used to drive a generator to produce electrical energy.

While wind energy is harnessed through the movement of air, other forms of energy conversions listed do not accurately represent what occurs in a wind turbine. For instance, electrical energy typically converts into thermal energy in processes involving resistance, but that's not relevant to wind turbines. Similarly, mechanical energy is not converted into chemical energy in this context, and gravitational potential energy involves the height of an object in a gravitational field, which is not a factor in the operation of wind turbines as they primarily operate based on the movement of air.
