Information having energy is well known since Boltzmann, as entropy is measured in J/K. I don't think that information is "equivalent" to energy. (Also, I don't think that mass is equivalent to energy either. Sure, if you add energy, you gain mass and vice versa, but since things (for example things with charge) can't be created or destroyed (not even with black holes or antiparticles), talking about the equivalence of energy and mass is total nonsense.)

I believe things with charge can be both created (electron-positron pair) and destroyed (electron + proton = neutron)

  Yes, you are right, you can destroy an electron with a positron, but then you destroy the positron too, so you have no information about "the energy of the electron". To be more concrete, bmacho equation, E = mc^2 + q*6*10^23 J/e holds for every experiment, every theory (standard model, GR). It states that energy is equivalent to mass and charge.

There have been tens of thousands of experiments demonstrating mass to energy conversion. It is the basic principle behind nuclear energy production. Mass energy equivalence is necessary to maintain conservation laws and has been proven by empirical observation. The total mass/energy in the system will not change, however the two can be exchanged for each other. > Information having energy is well known since Boltzmann Information having mass/energy has not been proven. There have been no experiments to support this argument. It is merely a theory. > ..as entropy is measured in J/K Entropy is not a conserved quantity since it will increase within a closed system. The Joules/Kelvin unit comes from statistical mechanics where temperature is defined as a change in entropy per increase in total energy. The entropy used in information theory is different, although related. Entropy in information theory is measured in bits.
