The US Environmental Protection Agency is developing an Energy Star rating designed to give energy efficiency guidance to IT directors buying PCs and servers.
Andrew Fanara, who manages the Energy Star programme at the US Environmental Protection Agency, said the programme aimed to encourage manufactuers to make PCs and servers energy efficient.
A study by Jonathan Koomey, a staff scientist at Lawrence Berkeley National Laboratory, last month reported that in 2005 the electricty cost associated with datacentres, servers and cooling equipment was more than £3.68bn.
In July, Energy Star is set to release a rating for desktop PCs, allowing buyers to assess their power consumption. The server rating is under development.
