The output energy in the desired form is only a part of the Input energy. The balance is the energy loss (usually in the form of diffused heat). It means the converter has less than efficiency. The balance is the energy loss (usually in the form of diffused heat).

Input–output model - Wikipedia

In economics, an input–output model is a quantitative economic technique that represents the interdependencies between different branches of a national economy or different regional economies. Wassily Leontief (1906–1999) is credited with developing this type of analysis and earned the Nobel Prize in Economics for his development of this model.
