Found an interesting label/award, which says that software is resources and enery-efficient. In our world with a big number of wasteful and bloated systems it can become a sign of quality one day, motivate creating better software and maybe even help to reduce a negative impact on the environment.

@abcdw Yes, I think Okular is the first certified software. At work, I also try to mind if a check needs to run on every server or if I can ask the hypervisor or use more efficient checks. Power usage costs double in the data center as you also need the cooling.
