Red Hat is 'greenest' operating system

Red Hat is working hard to deliver greener products and solutions. A recent
Network World test examining power consumption to determine the 'greener'
operating system validates Red Hat's efforts to move toward green computing.

Network World ran multiple power consumption tests using Red Hat Enterprise
Linux 5.1, SUSE Enterprise Linux 10 SP1 and Windows Server 2008 Enterprise
Edition on servers from Dell, IBM and HP. Red Hat Enterprise Linux ranked at the
top in keeping the power draw in check, pulling as much as 12 percent less power
than Windows 2008 on identical hardware. This reduced power draw was evident
across testing in both performance and power saving modes and transcended all
server models used in the test bed.

Red Hat is significantly involved in the development of projects that are
focused on saving power. Many provide benefits for customers today, as shown by
the Network World report, while others aim to provide even greater benefits in
the future. Efforts include, contributing member to www.LessWatts.org,
an Intel-sponsored project bringing together developers, users and sysadmins-all
in the effort to create a community around saving power on Linux.

Another interesting area of development concerns support for CPU clock
frequency scaling. Clock scaling allows changing the clock speed of a running
CPU on the fly.

Red Hat worked close with AMD to prove support for PowerNow, a technology for
power management.
