How Green is the Cloud?

An emerging wealth of evidence supports the argument that the flip-side of reducing our impact on our World’s resources – dependent upon how we approach ICT – is significant financial savings.

Green Cloud ComputingFor example, the adoption of Cloud – sharing pooled resources and facilities – will contain the viral growth of duplicate data centres across many enterprises.  This not only makes a case for Cloud as an energy-saver, but ‘pay for what you need and when you need it’ pricing models compete very favorably against the costs of traditional models.

Client devices offered in the Hardware as a Service vein and designed to be Cloud focused are typically very low powered.  In terms of battery life this makes them more practical for the mobile user – or in the classroom where keeping devices charged for the learning day presents its own logistical challenges.  Lower power is clearly greener and happily brings down electricity bills.

The Carbon Disclosure Project reports that a company adopting cloud computing can reduce its energy consumption, lower its carbon emissions and decrease its capital expenditure on IT resources while improving operational efficiency.

An energy study by Microsoft, Accenture and WSP claimed that a company with 100 employees can reduce energy consumption and emissions by more than 90% if applications are deployed in the Cloud.

And Cloud data centres are getting greener too –http://www.google.com/about/datacenters/.

Cloud computing offers other Green and cost benefits such as:

  • Fewer car journeys where support can be managed remotely, in the Cloud;
  • Increased employee productivity through more flexible, mobile working combined with much improved availability;
  • Improved device longevity with reduced dependency upon increasingly resource hungry Operating Systems and locally installed applications.
