Variations of the bath energy are compared with the information flow in localdephasing channels. Special correlated initial conditions are prepared from thethermal equilibrium of the whole system, by performing a selective measurementon the qubit. The spectral densities under study are ohmic-like at lowfrequencies and include logarithmic perturbations of the power-law profiles.The bath and the correlation energy alternately increase or decrease,monotonically, over long times, according to the value of the ohmicityparameter, following logarithmic and power laws. Consider initial conditionssuch that the environment is in a thermal state, factorized from the state ofthe qubit. In the super-ohmic regime the long-time features of the informationflow are transferred to the bath and correlation energy, by changing theinitial condition from the factorized to the specially correlated, even withdifferent temperatures. In fact, the low-frequency structures of the spectraldensity that provide information backflow with the factorized initialcondition, induce increasing (decreasing) bath (correlation) energy with thespecially correlated initial configuration. By performing the same change ofinitial conditions, the spectral properties providing information loss, producedecrease (increase) of the bath (correlation) energy.
