That depends what you mean with "it".
Heat energy
efficent
Electrical energy is transformed into heat energy. But that heat has to passed to the hair. So a fan operates in which electrical energy is changed into mechanical energy.
In a toaster electrical energy is changed to heat energy. This heat is what browns the bread to become toast.
Potential energy from food can be converted into kinetic energy and thermal energy in the body. When we eat, our bodies break down the food to release energy that is used for movement and to maintain body temperature.
potential energy is changed to kinetic energy when you push.

physical energy
The electromagnetic energy (electricity) the oven operates on is being converted into mechanical (sound) energy when the timer beeps.
Yes. Chemical energy, changed to heat energy, changed to mechanical energy.
Stored energy is typically changed into kinetic energy or thermal energy when it is used.
Heat energy can be changed into other forms of energy such as mechanical energy, electrical energy, or light energy through processes like thermoelectric conversion, thermodynamic cycles, or combustion.
