Being green
• Smart grid– Generation
• Traditional (bulk, point)• Distributed
– Transmission/distribution• Smart load
– Commercial and public-sector– Residential

Cisco EnergyWise
• Individual elements of an IT installation can be controlled individually, but a systems approach is likely to be more productive
• IT devices are interconnected by a network, so it is not unreasonable to embed system-wide energy-control intelligence into the network elements themselves
• Cisco EnergyWise comprises additions to IOS and the CLI that enable energy management
Flexibility
• Devices –– are assigned to domains– have names and roles– may have keywords stored in them– may have an importance (0-100) assigned to them
• EnergyWise commands can use these attributes
