Consumption of R-PI

• How to add usb webcam and WiFi to RPi model A without ruinning power consumption?
• RPi_Hardware
• Reducing power consumption

However, if you buy a model A it only uses 0.5 Watts at idle instead of 2 Watts. 
That's a big step in the right direction. 
I was also under the impression that the HDMI doesn't use any power unless something is connected?

It seems the most power reduction (below 200 mA) on R-Pi Model B can be achieved by desoldering the Ethernet chip (IC3 - LAN9512)
as done on frenetic rapport. 
I think we can still have the Ethernet port via the lower USB port using USB to Ethernet adapter. 
But I am not sure yet if I would take that option
