[GNU] Linux makes for greener computing
By Manek Dubash, Techworld
The UK Government reckons that servers with Linux installed are
greener than those running Windows.
That's because, according to a report by the Department of Government
Commerce about Open Source Software Trials in Government, open source
software has lower hardware requirements and needs less frequent
In particular, it said that: "for equivalent open source and Microsoft
Windows systems, the open source system will require less memory and a
slower processor speed for the same functionality." It points out that
Windows needs a hardware refresh every three to four years, while a
Linux box might need a new platform as infrequently as every six to
eight years - half as often.
The report continued: "Open Source operating systems such as Linux do
not usually have the regular major upgrades that are a feature of
Windows, and thus do not have the requirement that goes with these
upgrades for a new or upgraded computer to run them."
The report then concludes that the reduction in hardware demands
brings environmental benefits, because it translates into lower energy
requirements and less waste, "reducing landfill requirements and costs
arising from disposal of redundant equipment."
The report also coincides with Tory shadow chancellor George
Osbourne's call for the use of more open source software in
government. He said that the UK government could save in excess of
£600 million a year if more open source software was deployed across
But if the timing of the report is good news for the open source
community, it's possibly less welcome for others.
Microsoft Windows Vista has just been released to a flurry of
criticism from environmental groups such as Greenpeace who slammed
Microsoft for the hardware-hungriness of Vista, saying that upgraders
will "will trigger a deluge of e-waste in developing countries."
Beau Baconguis, Greenpeace's southeast Asia toxics campaigner, argued
that: "With Vista, Microsoft could effectively hasten the obsolescence
of half the world's PCs, especially in the absence of
fully-functioning global take back systems for PCs. Companies will
feel the need to upgrade more computers sooner - and when they do, the
world is unfortunately not prepared for the massive e-waste the
upgrades will generate."
Greenpeace went on to argue that Microsoft should have considered this
when producing its new OS.
It's a problem for which a solution will need to be found eventually.
While most enterprises have few if any plans right now to move their
desktops onto the new OS, most will eventually be forced to migrate as
Microsoft starts to implement its phased withdrawal of support for
Windows XP under its public life-cycle policy.
This is some way off, although the company has announced that the
availability of licences for Windows XP Professional would be
withdrawn for OEMs after 28 January 2008, and for system builders a
year later. Mainstream support for XP Pro ends on 14 April 2009 while
extended support - in other words, paid-for support - ends five years
Before that happens, Vista - or maybe even its more hardware-hungry
successor - will have become the only commercial OS choice.
