Big Data Goes Green

‘Cloud computing’ and its data centres’ vast energy demands could open opportunities for renewables.

Cloud computing, where software is delivered as a service to end users over the internet, is currently receiving a lot of attention. The term describes data-processing operations that are outsourced to server farms, instead of being powered on-site. These range from websites and remotely hosted networks, to digital storage space and individual documents.

Such are the developments, that software delivered over the web looks very similar to software operating on a personal computer, and is accessible from any computer in the world. Consequently, some IT sector analysts are predicting the death of the personal computer while others believe it will simply become another device to access the on-line world. Increasingly, the engine of the IT sector is composed of large-scale data servers that are driving the cloud-computing revolution forward. With regard to energy, cloud computing should result in lower costs for users and fewer greenhouse gas emissions by streamlining information-crunching into single facilities on speedy machines.
