How energy-efficient is cloud computing?

(PhysOrg.com) -- Conventionally, data storage and data processing are done at the user's own computer, using that computer's storage system and processor. An alternative to this method is cloud computing, which is Internet-based computing that enables users at home or office computers to transfer data to a remote data center for storage and processing. Cloud computing offers potential benefits – especially financial ones – to users, but in a new study, researchers have investigated a different aspect of cloud computing: how does its energy consumption compare with conventional computing?
