Last week in Serbia was marked by the green week initiative (SR), and this one is marked by freedom, it’s Creative Commons’ 6th birthday. This gave me an idea for this post. Use Linux to go green.

And how will Linux help you? By cutting your energy bills and lowering your e-waste production.

Few tests concluded that both Linux desktops and servers consume less power than Windows-powered machines.

Desktops: “When the Lenovo ThinkPad T60 was idling with Ubuntu 8.04 LTS “Hardy Heron” it had quite an advantage over Windows Vista Ultimate. Ubuntu was consuming five less Watts, which equates to more than 10% less power, over Microsoft Windows Vista. In our first server power consumption test, Vista Ultimate had consumed less power but it was just two Watts and both of these systems were consuming in excess of 170 Watts.”

Servers: “In most cases when sitting idle, Windows Server 2008 drew slightly more power than either Linux did on the same server. The exception was when Windows Server 2008 was running in power savings mode on the Dell server, where it drew on average 3% less power.”

Although, these results may be dependant on the actual test hardware, still it’s a good indication. Check out Intel’s LessWatts initiative, which aims to help you to lower your computer’s energy consumption if you use Linux. Also, there are tools that will help you make your Linux-powered computer consume less energy.

Another way it can help is by reducing your e-waste production. UK government conducted a study which showed that the typical hardware refresh period for Linux systems was 6-8 years, while Windows systems’ hardware refresh period was 3-4 years. Why is that? Consider that minimum requirements for Ubuntu, which is a fairly modern Linux distribution, are 64 MB of RAM, 4GB of HDD space and 300 MHz x86 processor. That configuration wouldn’t be able to run all the nice graphic effects, but you would have a ready-to-use system. For nice graphic effects, consider installing it on at least 700 MHz CPU with 256 or 384 MB of RAM. And there are also distributions which can work on even older configurations, like DSL or Puppy Linux. If you have an old computer which you don’t use, install one of those on it. It will serve nicely to surf the Internet, or to work on your documents.

So, go ahead and try it, if you’re not using it already. Go green .
