*E*of a graph

*G*is equal to the sum of the absolute values of the eigenvalues of

*G*. In 2005 Lin et al. determined the trees with a given maximum vertex degree Δ and maximum

*E*, that happen to be trees with a single vertex of degree Δ. We now offer a simple proof of this result and, in addition, characterize the maximum energy trees having two vertices of maximum degree Δ.
