Is it possible, to turn off the HDMI video component? My Pi operates headless so there ist no need for me to have a video out component. If yes, how much power will be saved?

I think you can just switch it off, but I do not know how much power is saved.
Switch off
/opt/vc/bin/tvservice -o
Switch on
/opt/vc/bin/tvservice -p
