Which of the following transformation occur (in different kind of waves) a wind turbine creating eletricity eletric gutair a campfire

A wind turbine creating electricity converts the kinetic energy of the wind to mechanical energy for movement of blades and finally to electrical energy.

A electric guitar first converts kinetic energy to  electrical energy and then electrical energy is converted to sound energy.

A campfire converts the potential chemical energy into heat and light energy by the process of combustion.

As we know from the conservation of energy, it is neither created nor destroyed, it only converts from one form to another.
