This Entropy/Thermodynamics/Information Wikipedia article is as close as one can get to what the standard scientific treatise of the link between energy, information and entropy.
From the information is physical -> Szilards Engine.
The global entropy is not decreased, but information to energy conversion is possible..
This appears to put information on an equal footing as mass or energy, in the sense that it is conserved in general, but can be also transformed between energy and mass. It is tempting to follow the lead of the ID ers to intimate that informational entropy can either stay the same and increase but not decrease - My view is different, in that I believe that information can be generated through the use of energy in naturally occuring metabolic systems. .
My first postulate is that information can increase (be created) within a boundary if the entropy is increased outside the boundary..
My second postulate is that some of the energy within the boundary must necessarily increase the information if entropy is increased outside the boundary. This would mean that stars like the sun, that send a lot of waste heat outside of itself, are becoming more ordered on the inside, in proportion..
Thus random processes could not increase information, but metabolic processes can, by separating where the information is stored and expelling its increasing entropy to where it isn't..
To destroy information, the directionality of increased entropy must be directed back to within the boundary (making the rest of the universe slightly more ordered).
Neither the generation, nor the destruction of information is a perfect process, and there will be some leakage of energy to information..
