This paper finds the extended energy of some special class of graphs and their complement graphs. Let $G=(V, E)$ be a simple graph with vertex set $V(G)=\left\{v_1, v_2, \ldots v_n\right\}$ and edge set $E(G)$. The Extended energy $E_{\text {ext }}(G)$ is defined to be the sum of the absolute eigen values of its extended adjacency matrix $A_{e x t}(G)$.
