What's New In The Revised Blue Angel Criteria
Quoting: What's New In The Revised Blue Angel Criteria - KDE Eco —
The biggest change is the scope of the label. In the past it was limited to desktop software. With the updated version, the criteria also include software on mobile devices and server software or a combination of these categories, such as a web service with mobile and desktop clients.
The biggest challenge is the measurement of the energy and resource efficiency for these new categories, which requires a more flexible approach and must accommodate scenarios where the measurement cannot be done by inserting a meter in front of the power supply of a single device. The new criteria address this by defining applicable methods for the measurement of mobile and server applications.
The extended scope covers a much broader range of software. For KDE the desktop category is most relevant, but of course a lot of software also interacts with a server component, for example an email client like KMail, which could now be treated and assessed as a combined client-server system to give more realistic and relevant results.
