What term describes energy that cannot be used to do work?

Entropy describes energy that cannot be used to do work. It measures how energy becomes dispersed and more disordered; as energy spreads out, less of it remains available to drive processes. The energy that can still do work under the current conditions is captured by free energy, while enthalpy is the total energy content and kinetic energy is energy of motion. So entropy is the term that specifically refers to unusable, dispersed energy.
