An energy management apparatus manages energy consumption of a machine, which has a supply part ( 14 ) for supplying energy and a consume part ( 10 ) for consuming the energy supplied by the supply part, so that the energy consumed by the consume part is positively saved. An operating part operates the consume part by using the energy supplied by the supply part. An acquisition part acquires an energy conversion characteristic, as an energy efficiency, from an input energy ( 40 ), ( 42 ) supplied to the consume part into an output energy output ( 44 ), ( 46 ) from the consume part. A change part changes an operating condition of the consume part based on the acquired energy efficiency so as to improve an actual value of the energy efficiency.
