The thermodynamic approach proposed is purely supply side and is expressed in GJ/t. A mineral can be considered very rare and thus "thermodynamically critical " whereas when using only the consumption side other factors come into play such as declining in consumption due to better substitutes or disuse phase out of technology etc.

There is yet another way of expressing the second law of thermodynamics. This version relates to a concept called entropy.By examining it we shall see that the directions associated with the second law—heat transfer from hot to cold for example—are related to the tendency in nature for systems to become disordered and for less energy to be available for use as work.
