heating with renderings

V-Ray V-Ray Common Hardware

I always thought of it as a real cool thing- instead of heating your rooms, just rendering some cool stuff.
Recently my power meter was swapped with a new digital one and I started to be curious how much electricity I actually burn with my render-test.
I got:
I-7-5960X running at 4.0Ghz-PSU corsair rm650i
I-7-3770k running at 3,8(?)Ghz- PSU bequiet BQT L7 350W
2 nodes double E5-2670(more or less the Juraj-buil) with seasonic g series 650 W

eyeballed 5-6 days 24/7 rendering burnt 175kWh- yes, it was cozy and warm… :smiley:

Do you guys consider this as ‘normal’-numbers?
I read something about the PSU being most efficient at 50% load. My PSUs are obviously too weak, how much impact would a better efficiency have?
I’m really concerned because this 6 days rendering wasn’t paid- just tests…

Seems quite reasonable consumption on 4 machines running ~130 hours.

Note
In few EU countries (Netherlands, Germany, France…) few companies are already getting on with using smart & efficient solutions.
Check eRadiator, Nerdalize, Eneco, Qarnot Computing (presented in 2015 on Blender Conference)…

For example:

Fight against oil&gas giants continues…

Thanks for the links- really interesting approach. Hopefully I can get some render jobs this winter… and save the heating! :wink:
