The Energy Efficiency Potential of Cloud-Based Software A Case Study Review by Aidan Windebank
What is Cloud-Based Computing? • Web based service to host applications. • Email, productivity software & other applications. • Cloud is large, energy efficient server system.
How Much Energy Could Be Saved? • Estimated 80-90% Energy Savings • Servers account for 1-2% Worldwide energy use
The CLEER Model Cloud Energy and Emissions Research Model • Open Access • Fully Transparent
U.S. Case Study • Used CLEER model to asses energy savings in US business sector. • Looked at most commonly used software applications. • Currently hosted on local servers.
Limitations • Access to publicly available data only • Many factors are assumed or predicted • Further use will curb uncertainties
