Computer data centres could save millions of dollars if they follow the moon to guide their electricity use, it has been claimed.
US researchers at the Massachusetts Institute of Technology, web application company Akami and Carnegie Mellon University have released a study which shows data usage requests could be re-routed to centres where electricity costs are cheaper, Network World has reported.
The academics explain that as power is typically less expensive at night, there are savings to be made by "following the moon".
According to the research, the technology is already in place to make this happen.
People just leaving networking courses for an IT career will be aware of the move towards global data networks and cloud computing.
The internet's popularity is leading companies that are responsible for data storage to seek cheaper solutions to their electricity needs.
Google, for example, has removed powered chillers from its data centre in Belgium, preferring instead to take advantage of free cooling provided by fresh air.
