Cloud computing could help data center operators trim energy costs and reduce carbon emissions, according to a Pike Research report. Cloud computing, which has been steadily gaining popularity, is expected to see revenue grow from $46 billion in 2009 to more than $210 billion in 2015.

Clouds are less expensive to operate than data centers. Pike expects most work conducted today in data centers to be outsourced to cloud computing by 2020.

The report asks these key questions:
• What cost advantage does public cloud computing have over data centers?
• What are key strategies among cloud computing providers for energy efficiency?
• How can companies improve sustainability by switching to cloud computing?
• What energy efficiency ROI does cloud computing present?
