It is important, because from been useful it converts to a less useful form.
"Unavailable for doing work" is related to the Second Law of Thermodynamics.
Second Law of Thermodynamics
The Second Law of Thermodynamics.
Actually Murphy's law has been suggested (humorously) as "the fourth law of thermodynamics". It is only peripherally related the the second law. One of the implications of the second law is that an increase in disorder in the universe is a consequence of natural processes. Some have suggested that Murphy's law (If any thing can go wrong, it will.) is an example of this. Strictly speaking - this is quite different from the 2nd law but when someone screws up, it sure does tend to cause a lot of disorder!
The work of Sadi Carnot, a French engineer, on the efficiency of heat engines in the early 19th century led to the formulation of the second law of thermodynamics. Carnot's insights on the limitations of heat engine efficiency laid the foundation for the development of the second law, which eventually became a fundamental principle in thermodynamics.
There is no commonly accepted law by that name, as far as I know. Two important laws about energy are the First Law of Thermodynamics and the Second Law of Thermodynamics.

Second Law of Thermodynamics
There were several mathematical ideas which interacted with thermodynamics. By far the most important of these is statistics.Some physicists believe that the Second Law of Thermodynamics is the one physical law of whose validity we can be totally certain, because it is based on statistics.
The fact that usable energy is always lost in an energy transfer is due to the second law of thermodynamics. This law states that entropy, or disorder, tends to increase over time in a closed system, leading to the loss of usable energy in the form of heat.
He may very well know it, but he seldom uses it, as it is not important to his work.
True
According to the second law of Thermodynamics, the amount of usable energy will continuously decrease.According to the second law of Thermodynamics, the amount of usable energy will continuously decrease.According to the second law of Thermodynamics, the amount of usable energy will continuously decrease.According to the second law of Thermodynamics, the amount of usable energy will continuously decrease.
The second law does not allow complete conversion of heat into work.
The Second Law of Thermodynamics.
The second law of thermodynamics states that a system with no energy input and no energy losses will tend toward dissolution.
