This invention discloses an intelligent framework for the overall management of energy allocated to components of a system. When conservation is desired or a shortage occurs, it is desirable to modulate energy to components, or to notify components and allow them to modulate themselves. It also discusses the establishment of a standard communications API between entities and components within the system. Among other things, this framework: manages device and entity enrollment into the system; provides an interface to heterogeneous devices; establishes standard communication methods between entities and components; dictates throttling to entities and components when conservation is required; and monitors energy throttling and compliance with modulate requests.
