I have a wattmeter and measured my machines during crunching.

The question is:How many KWh need my machines to get 1 Mio Cobblestone?
Calculated for distrrtgen
1 WU = 8758 Points
1000000 / 8758 = 114,181 ~ 115WU's needed.

Machine 1: Pentium 2.6GHz Northwood, ATI HIS Radeon HD4670 AGP
Duration per WU = 4h 10 min ~ 4,2h
115wu * 4,25h = 483h
Measured crunch-power = 140W
483h*140W=67620W ~67,62KWh
1Mio = 67,62KWh
~~~~~~~~~~~~~~~

Machine 2: Laptop i3 2.6GHz NVIDIA GT540M
Duration per wu = 2h 15min ~ 2,25h
115wu * 2,25h = 258,75h
Measured crunch-power = 62W
258,75h*62W=16042,5W ~16,0425KWh
1Mio = 16,0425KWh
~~~~~~~~~~~~~~~~~

Machine 3: ATOM 1,6GHz, ION GPU
Duration per WU = 17h 30min ~17,5h
115wu * 17,5h = 2012,5h
Measured crunch-power = 28W
2012,5h*28W=56350w ~56,35KWh
1Mio = 56,35KWh
~~~~~~~~~~~~~~~

Machine 4: V8-Xeon,2,4GHz NVIDIA GTX570, GTX470, GTX470
data from project primegrid:
per 24h = 1,6Mio
Measured crunch-power = 860W
24h*860W=20,64KWh/1,6Mio =12,9KWH per 1Mio
1Mio = 12,6KWh
~~~~~~~~~~~~~~
distrrtgen
GTX570 need ~662s/wu, 115wu*662s=76130s/3600= 21,14h/Mio
Because we have 3 GTX570 we must divide by 3
21,13h/3=7,04h per Mio
860w * 7,04h=6054,4W ~6,054KWh per Mio
1Mio = 6,054KWh
~~~~~~~~~~~~~~~
distrrtgen
GTX680 need 485,06sec/wu, 115wu*485,06s=55781,9s/3600s= 15,5h per Mio distrrtgen.
If we have 3 GTX680 we must divide by 3
15,5h/3=5,16h per Mio
We assume we need 860W with V8-Xeon.
860w * 5,16h=4437,6Wh ~4,4376KWh
1Mio = 4,4376KWh
~~~~~~~~~~~~~~~~

Remark:no CPU work done, all GPU work
I can confirm: CPU usage on all 4 machines slower than 3% (mostly 0,5-1,5)

Sure we can not direct compare primegrid against distrrtgen.
The measured results are surprizing and very interesting.
If we compare all 4 machines, V8-Xeon is the most effective.
V8-Xeon
~6,05KWh per Mio with 3 GTX570
~4,44KWh per Mio with 3 GTX680 (precalculated on real data)

As soon as I have a new PSU, I will test v8-Xeon with distrrtgen to get real data.

It is mostly effective to use modern latest hardware.

What about ATI

A good sample for effectivity calculation are computers of james Ying.
userid=15715
lets have a look at

hostid=23173
Intel(R) Xeon(R) CPU E31230 @ 3.20GHz
[4] AMD AMD Radeon HD 79x0 series (Tahiti) (3072MB) driver: 1.4.1720
running (distrrtgen) v3.52 (opencl_ati_101)
runtime:436 sec/wu
115wu * 436 = 5140s/3600s=13,93h
if we have 3GPU we divide by 3
13,93h/3=4,64h per Mio
if we assume we need 860W with V8-Xeon
860W * 4,64h=3990,4 ~3,99KWh
1Mio = 3,99KWh  (3 HD7970)


if we have 4GPU so we divide by 4
13,93h/4=3,48h per Mio
if we assume we need 860W with V8-Xeon
860W * 3,48h=2994,47 ~2,994KWh
1Mio = 2,994KWh (with 4 HD7970)

This means ATI HD7970 with new OpenCL app (opencl_ati_101) can beat a GTX680 running (distrrtgen) v3.48 (cuda23)
runtimerelation HD7970/GTX680:436s / 485s , difference 49sec

Reference: HD7970 runtime=423s
hostid=39986
Intel(R) Core(TM) i5-2500K CPU @ 3.30GHz
AMD AMD Radeon HD 79x0 series (Tahiti) (3072MB) driver: 1.4.1720

Reference: GTX590 runtime=848s (anonymous platform runs OCL version, maybe 2 at once?)
hostid=41489
Intel(R) Core(TM) i7-2600K CPU @ 3.40GHz [Family 6 Model 42 Stepping 7]
[2] NVIDIA GeForce GTX 590 (1535MB) driver: 304.79

Meanwhile my laptop passed 30Mio total. All GPU work. If I run cpu work additional the machine overheated.
 i3_gt540m_30Mio_total

1Mio = 16,0425KWh
16,0425Kw/Mio * 30Mio = 481,275 KWh
30Mio = 481,275 KWh
How much money cost electricity in France ?
the contract has 2 prices dependant from daytime
from 2:00h-8:00h and 14:30h-16:30h summary 8h(a third of a day) price= 0,0567 Euro/KWh
rest of the day 16h(2 third of a day) price 0,0916 Euro/KWh
so we can say
10 * 16,0425 KWh = 160,425 KWh * 0,0567 Euro/Kwh =   9,096 Euro
20 * 16,0425 KWh = 320,85  KWh  * 0,0916 Euro/KWh = 29,389 Euro
Summary 38,48586 Euro
30 Mio = ~38,49 Euro
~~~~~~~~~~~~~~
This is still true for the Laptop

100 Mio distrRTgen in sight...
passed 98 Mio distrrtgen
the last two Mio will be calculated by GT540M, ATI HIS4670 AGP, ION
