Abstract: Disclosed are an energy information system, and a method and a device for processing energy information. The method comprises: collecting, by means of at least one information gateway, energy information of at least one energy apparatus, wherein the at least one information gateway is connected to the corresponding energy apparatus; acquiring, by means of a central processing unit, the collected energy information, and transmitting the energy information to a server; and performing, by means of the server, analysis on the energy information to obtain an analysis result, wherein the analysis result is used to control the at least one energy apparatus. The present invention solves a technical problem of low energy utilization efficiency resulting from lack of a turnkey solution for an energy Internet.
