Google Claim Between 65 percent to 85 Percent Decrease in Energy Costs by Migrating to Google Apps

Google Apps is a cloud-based service that features a suite of collaborative tools, namely: Docs, Gmail, Calender, Site, Groups, Video, Talk and Marketplace. The suite is available for personal, business, schools and government use and has a rapidly growing customer base with over four million business already migrated to the service.

Urs Hoelzle, Senior VP for Technical Infrastructure wrote on the Google Blog, “We’re obsessed with building energy efficient data centers that enable cloud computing.” “Last year, we crunched the numbers and found that Gmail is up to 80 percent times more energy-efficient than running traditional in-house email.”

Google said that they are able to produce these sorts of cost savings because servers in its data center make more efficient use of their computing and storage capacities, and its maintenance and administration costs are less. Hoelzle furthermore commented, “A typical organisation has a lot more servers than it needs – for backup, failures and spikes in demand for computing. Cloud-based service providers like Google aggregate demand across thousands of people, substantially increasing how much servers are utilized.”

Google backed up this claim with information from a study by the Carbon Disclosure Project. By migrating to the cloud, US companies with over $1 billion in earnings could save $12.3 billion and up to 85.7 million metric tonnes of CO2 by 2020. UK companies would save on average £1.2 billion and more than 9.2 million metric tonnes by the same year.

An eye-opening article by Jaymi Heimbuch, titled “The cloud is only as green as the people using it” details that cloud computing can offer major savings of energy costs however that is dependent on how it is used. Kerry Hinton, an electrical engineer at the University of Melbourne states that “When clients make the connection wirelessly – a much more energy intensive data connection – their energy expenditure skyrockets, making the transportation of data an even bigger part of the efficiency equation”
