Finally I had time to assembly measurement tools. Results of 
measurements and calculations are bellow.


Device                     | Current A | Power W | daykWh | month kWh | 
year kWh | cost/y EUR
---------------------------------------------------------------------------------------------
My desktop AMD64 X2 4000+  |   0,22    |    48   |    1,16 |      34,6 | 
415,2    |  83,04
---------------------------------------------------------------------------------------------
Grase P4 3000 GHz          |   0,25    |    57,2 |    1,32 | 39,6 | 
475,2    |  95,04
---------------------------------------------------------------------------------------------
Grase NB P-mobile 1,6GHz   |   0,06    |    13,2 |    0,32 | 9,5 | 
114,0    |  22.80

Measurement where taken at 220 VAC side. Digital tester, 20A AC range.
Measurement taken at standby state (machine up, OS up, grase up)
My Desktop is here for comparison only.
Energy cost taken from EUROSTAT. Average price for EU 0,2EUR per 1kWh.

Results shows aprox. 4.3 times less power consumption.
