  Using canonical typicality method, we reconsider the study of dark energy
effects on four dimensional black holes. Concretely, we investigate the
associated influences on the spectrum of various black hole backgrounds
including the charged and the rotating ones. For such black hole solutions, we
first elaborate analytically the corresponding radiation spectrum, the Hawking
temperature and the dark information. Then, we discuss and analyze the
corresponding findings. This work, recovering the results of the Schwarzschield
black hole, confirms that dark energy can be considered as a cooling system
surrounding the black holes providing a colder radiation and a slower Hawking
radiation process.
