Probably indicative of your shallow understanding of the topic.
So ill explain: Out of the total energy of a closed system, not all can ever be used, due to ...*drumroll* entropy.
It is widely held that the total energy (potential, kinetic, fields) of the Universe is zero, as if the Universe came from nothing. Entropy has SI units (Joules/Kelvin); enthalpy is Joules/kg.
