Cloud computing has proved to be a major breakthrough in terms of green computing. Cloud computing is one of the few technologies which offers the possibility of reducing energy consumption and carbon releases with almost negligible disturbance to business activities. The positives of this technology in terms of servicing and power consumption are apparent. In spite of all the positives, there are speculations about the efficiency of energy management in cloud computing. In this paper, the authors try to suggest a possible alternative to the various power saving techniques in cloud computing. The solution suggests implementation of ACPI (Advanced Configuration and Power Interface) in cloud servers. The various power states can be embedded in servers and switches to use optimal power when needed.
