A method for attributing a portion of a level of electrical power consumption by a server to a virtual machine executing on the server, includes determining a level of electrical power consumption of a server. The method includes identifying a level of load placed on the server by a workload executing on the server. The method includes attributing, by a power apportionment module in communication with the server, a portion of the level of electrical power consumption of the server to the workload, based on the identified level of load. The method includes providing, by the power apportionment module, to a user, an identification of the attributed portion of the level of electrical power consumption.
