  Recently, it was shown in [1] that black holes are the source of dark energy.
In [2-5], the truth or falsity of this concept has been discussed. We briefly
state the arguments raised in each of these papers, but our main goal is not to
accept or reject these debates. Rather, in this note, we show that black holes
in specific structures, such as the Reissner-Nordstrom (R-N) black hole in the
presence of quintessence, string cloud, and perfect fluid, can produce a
repulsive force with respect to the weak gravity conjecture mechanism that
overcomes the gravitational force.\textit{ We discuss these repulsions forces
in a population of black holes of the same family can be considered as an
auxiliary factor (albeit a weak factor) for the expansion of the universe}.
