Let $G=(V,E)$ be a simple graph. The energy of $G$ isthe sum of absolute values of the eigenvalues of its adjacencymatrix $A(G)$.In this paper weconsider the edge energy of $G$ (or energy of line of $G$) which is definedas the absolute values of eigenvalues of edge adjacency matrix of $G$. We study the energy for the line of specific graphs.
