The document discusses using virtual power analytics and linked data to help enterprises better manage their IT energy use. It proposes a dashboard tool that would provide a holistic view of an enterprise's IT energy management by connecting different data sources using linked data. The tool would allow analyzing and comparing the power consumption of different devices in real-time. It would also provide a life cycle assessment report. The goal is to help organizations reduce their ecological footprint and costs by better understanding how energy is used within their IT systems.

4. Research Question
What can be done to help organizations reduce the
ecological footprint of their IT devices?
 Re-invent their business policies
 Adapt the business practices
Making the businesses more environmentally sustainable and cost less.
One possible solution: Help them understand how energy is being used
Energy Informatics
Analyzing, designing, and implementing information systems to increase energy efficiency
