With electricity prices continuing to skyrocket and processors getting ever hungrier for power, it was only a matter of time before Microsoft chimed in with claims that its latest software can cut energy bills. A Microsoft white paper released this week asserts that Windows Server 2008 can cut power consumption by 10% compared with Windows Server 2003 out of the box, and much more if running virtualized.

Microsoft compared power consumption between two installations on the same server with two dual-core processors and 4 GB of RAM, one running Windows Server 2003 R2 Enterprise x64 Edition with SP2 plus hot fixes, and the other running Windows Server 2008 Enterprise Edition, with a hard drive formatting in between.

The company found that Windows Server 2003 used as much as 10% more power despite only being able to deliver 80% of the maximum throughput as its successor. Microsoft attributes these improvements partially to power management features that Windows Server 2008 has enabled by default, like the automatic adjustment of processor performance based on workload.
