This article should show that we are advocating to comply with the Energy Star specification and all that comes along with is. GreenIT might be the buzzword that applies best.

The document is meant to be some kind of tutorial which describes how to measure power consumption on linux based systems with open source tools. It also refers to the EnergyStar standard/specification in a slimmed way to get some real live reference. It's meant to be a guide for both high skilled and not that skilled people to get a step by step manual of how one can reasonably measure their power consumption in an easy way. For more details, look at the document below.

Presentation about EnergyStar given at FOSDEM 2008:

  • What does EnergyStar actually stand for. What are the key facts regarding laptops. Don't we just have to blame the manufacturers?
  • What it makes interesting for both developers and users. Is openSUSE ready?
  • How to test your laptop for EnergyStar compliance

Energy Star Compliant kpowersave and gnome-power-manager

The two default applications kpowersave and gnome-power-manager as shipped with openSUSE are not fully Energy Star compliant yet. Thus, there are packages which fulfill the requirements at the following location:

  • openSUSE Factory: [4]
  • SUSE Linux Enterprise Desktop: [5]
