Step 3: Use Linux

Picture of Use Linux
Windows and OS X have ever increasing system requirements and thus consume more and more energy. Linux on the other hand, can run on almost any computer, old or new. My favorite distro is Ubuntu. There are several guides on how to install Ubuntu, so I won't go into details. Thanks to http://www.whylinuxisbetter.net/items/environment/index.php?lang= for this great point about Linux.
