Entropy can be defined as the added information needed to define a change in the status quo of a system. For example, going from one cell into two increases entropy and information. For entropy to increase it needs energy. This is why entropy is associated with the inefficiency and/or waste heat coming from a system. The waste heat provides energy, while the inefficiency requires additional information to define the system compared to the ideal system. In Chemical engineering, entropy is a measurable quantity and is needed to close energy balances.
Since the entropy of the universe has to increase, and since entropy needs energy, this means that the available energy of the universe decreases over time. The energy is conserved within entropy, but is net irretrievable since entropy needs to increase. You can't push two cells back into one. That enegy is conserved by irretrievable. Eventually all the energy of the universe will become irretrievable but conserved via entropy, since entropy needs to always increase.
An interesting implication is, since energy is conserved within the entropy, and since entropy has a connection to all that information needed to define changes within the status quo, then this information has to be conserved. If the information is not conserved then the conservation of energy is not valid.
Add it up. We start with energy. Some of the energy goes into entropy and becomes irretreivable. You can get that energy back, but it requires more energy than you will get back. It is net gone since entropy has to increase. If entropy is connected to information, and energy has to be conserved, and all the energy is in entropy, then the entropy information is conserved. It has irretrievable energy to perpetuate it.
