Businesses that choose to run business apps in the cloud can help reduce energy consumption and carbon emissions by a net 30% or more versus running those same apps on their own infrastructure. These findings, from a study commissioned by Microsoft, Accenture and WSP Environment & Energy, demonstrate cloud computing's potential to operate business apps more efficiently.
The study assessed the carbon footprint of server, networking and storage infrastructure for three different deployment sizes (100, 1,000 and 10,000 users), finding that smaller the organization, the larger the benefit of switching to cloud. When small organizations (100 users) move to cloud, effective carbon footprint reduction could be up to a 90% savings by using a shared cloud environment instead of their own local servers. For large corporations, the savings are typically 30% or more in energy consumption and carbon emissions using cloud apps. In a case study with a large consumer-goods company, the team calculated that 32% of emissions could be saved by moving 50,000 e-mail users in North America and Europe to Microsoft's cloud.
