Linux has quickly gained the reputation of being the most eco-friendly server operating system. In fact, it is now regarded as being more energy efficient than the more popular Windows Server 2008. Yes, Microsoft Windows is still the most preferred desktop OS across the globe but with green issues such as reducing carbon footprints of operating systems come to the fore, its monopoly could soon be seriously challenged by Linux.
Some of the important features that make Linux a distinctly greener operating system include:
Further, Linux is perhaps the only OS that gives so many options regarding running only those application that are actually needed by the user. Using Linux means that there is minimum scope for computing overhead and the applications running in virtual environment are also kept under check. This helps in making small but vital, direct energy savings, on a daily basis.
Example — Tickless Kernel: Customized Power Savings
Linux OS offer a unique tickless mode which is presented as an option to minimize the power consumption. This is done by keeping the processor in a dormant mode, when not in use and the kernel activates the processor along user-defined automated intervals. This ensures that the processor consumes electrical energy only when it is actually needed to perform certain functions. This helps in saving power across notebooks or servers without compromising on the computing efficiency. The tickless kernel is regarded as an on-demand processor scheduling tool.
A perennial problem with Windows-based hardware devices has been their shorter lifecycles which essentially means that they have to be thrown away after short periods of use. This has a damaging impact on the environment. However, there aren't any such problems associated with using Linux, as its compatibility with older hardwares is much higher when compared to Windows and Mac OS.
Consider This — It has now been proven through recent research and energy analysis that on an average, Windows users are forced to upgrade their desktops nearly twice as many times done by Linux users.
Also, Linux needs much lesser processing power which helps in keeping new production demands to the minimum and hardware dumping due to OS demands is almost negligible. Fewer computing equipment parts/spares means decreased ecological hazards such as upsetting the ecosystem with computing spare landfills and polluting it with chemically-enriched hardware equipment.
There are many Linux-focused green initiatives that are being considered by leading computing solutions providers like IBM and Intel. Linux is the most recommended choice when it comes to eco-conscious PC users who don’t want to make the environment suffer because of their computing needs.
However, the debate is still going on whether Linux is the right choice for greenest operating system. We have no option at the moment but to wait and watch.
