Abstract:
Green IT was developed from the growing concerns about the rise of the Information Systems energy cost and power consumption along with the need for an environmentally efficient image of the organization. This work addresses and links three main concerns: enterprise architecture modelling, need for energy cost cuts and energy efficiency of Information Technology. It describes a new method to estimate the IT architecture energy costs and CO2 emissions, based on the technology layer of the enterprise architecture, and some solutions for solving or, at least, reducing the environmental impact of the latter.
