The hairdryer is provided with 1500 J of electrical energy per second
Of this 1500 J, 1300 J of energy is actually used and converted to useful thermal energy per second
The remaining energy, 1500 - 1300 = 200 J is dissipated

Dissipated energy

The energy that is not efficiently transported or changed is wasted energy.
We cannot create or destroy energy.
An employable type of energy is created through transformation.
Only a portion of energy that is changed or transferred can be done so in a way that is helpful.

Thus, 200 J of energy is wasted by the hair dryer.
