The energy of a graph was introduced by I.Gutman and its bound were obtained by R.Balakrishnan. Subsequently the Minimum Dominating Energy was introduced by R.Rajeshkanna.Then Mean Energy (M - energy) was introduced by LauraBuggy, Amaliailiuc, KatelynMccall, and Duyguyen. In this paper, we studied the Mean Domination Energy for some standard graphs and obtained its bounds.
