lol larry all your green questions are cracking me up.
My computer sits and idles at 400W.
Yup thats more power then some who have posted on load.
I cant Sleep it or suspend the PC's due to its complex LC eq, the sleep restart cycles are very bad on LC pumps.
(i havent lost a single pump on this system, while i have lost 3 on a system which sleeps, so i decided no more Sleep cycles on my LC systems)
So it guzzles 400W even if im not home 5-6hours each day.
Anyhow... with the power savings on today's new processors, i dont think u need to worry that much.
The difference honestly will be less then a few 100W on the idle / off position.
The power draw on the used state will also be very small if you consider that your not cryptomining bitcoins or something which requires your PC to be on load all the time.
I honestly think your thinking too hard about power draw and power wastage.
We havent used anything that inefficient in power since prescott days of the P4.
I tell my friends who are "green" the same thing.
If they want to save electricity, replace your home lights to LED's, as you will net a bigger benifit.
Even turning your AC to 75F instead of 60F will net u a much greater benefit then putting your PC to sleep all the time.
Right now i think your trying to milk the VERY last portion on the energy grid in trying to conserve power. Which also is the hardest to do, as the net benefits on that end is very small.
Well, going from an overclocked Q9300 @ 3.0 and HD4850 card (280W), with a 26" LCD (65W), to a C-70 (15W) and a 24" LED LCD HDTV (25W) should def. make a difference in temps.
This isnt even on a the same floor tho.
The 4850 which probably constitutes for 40% if not more of the power draw vs the C-70 Ivy wasnt factored in.
Also the GPU prowess of the 4850 vs HD2500 is very big.
In a relationship grid... ud save more power % wise going from a magnetic to a SSD.
but again... your looking at the very bottom of the ways one can save power.
When u factor it in on the total demand power of the entire unit, it translates to pocket change.
