The Cisco Energy Management Suite aims to enhance energy efficiency in enterprise environments by providing visibility and control over various networked devices and systems, with potential savings of 15-35%. It supports a wide range of devices across multiple vendors without requiring additional hardware or network changes, allowing for agile deployment and quick time-to-benefit. Case studies highlight significant reductions in energy consumption, such as a hospital achieving a 30% decrease and a school district saving $31,500 annually.
