"The notion of sustainability is an important issue really for all of us," Ballmer said at a press conference at CeBIT 2008. "We are focused on opportunities to reduce power consumption by the IT industry."
Microsoft said it had reduced power consumption in Windows Server 2008 by 40%, which would have a knock-on effect for datacentre energy needs, Ballmer said.
The software giant has reduced power consumption at both the PC and server level. Windows XP used 100 watts per hour during PC idle time, while Vista uses three watts per hour, according to Microsoft.
Ballmer also announced the rollout of Search Server 2008, a software that complements higher end functions of Office Sharepoint Server, and the release of beta versions of hosted Sharepoint and Exchange services for cloud computing.
"We will now have Sharepoint and Exchange available to organisations," Ballmer said. "Our strategy with all these online services is to let customers take advantage of the power of the cloud, but with control over enterprise needs."
