Abstract The energy of a graph G is the sum of the absolute values of the eigenvalues of the adjacency matrix of
G． In this paper，using formula of circulant matrix eigenvalue and the inequality technique，we discuss some lower
bounds of energy for some circulant graph，and extend the conclusion in some literatures．
