TΔ S is the part of the energy that can be converted into work.

In an irreversible isothermal expansion of an ideal gas against constant external pressure, the heat absorbed equals the work done by the gas.

Heat taken from a single reservoir can be completely converted into work in a reversible isothermal expansion of an ideal gas, with no other change in the universe.

A decrease in Gibbs energy at constant T and P measures the unavailable energy of the system.
