Actually, no, it isn't soon recovered.
Decade ago (2004) machines still had sleep mode, Energy Star, (and EU equivalent), auto-scaling of processor speed, disk sleep, etc.
A decade ago we were already running Core 2 Duo, and Celerons, and they were pretty good as far as energy usage.
Yep, older desktops don't consume an awful lot more energy than current ones. If you were to look at the efficiency (cost/cpucycle), that would be a different issue, but not really relevant (for a desktop).
You have to go back to the 486 days to find machines that are truely expensive to run, and nobody is going to be doing any serious work on that processor unless it is sitting in a corner running headless.
The last one we had was a firewall, decommissioned some years back. I'm not even sure if they were really much more expensive than todays regular desktop. -- Per Jessen, Zürich (17.4°C) http://www.hostsuisse.com/ - virtual servers, made in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
