Systems and methods of analyzing energy consumption using node similarity are disclosed. An example of a method may be carried out by program code stored on non-transient computer-readable medium and executed by a processor. The method includes assigning a similarity score to a plurality of nodes using at least one of: domain based rules, attribute based similarity metrics, and machine learning. The method also includes identifying a similar node from the plurality of nodes, for a node under consideration, based on the similarity score. The method also includes determining energy consumption of the node under consideration based on energy consumption of the similar node.
