In Linux, is it possible to know which processes consume most battery energy at the moment?

Yes, powertop. Look at the screenshot:
But powertop hasn't 100% precision, CPU isn't the only battery consumer. Use also iotop for the disk activity.

thanks, wakeups-from-idle per second should be a small number - 17.4 on the picture, in my case it's 800-900. most wakeups are caused from network card(which is needed) and SingalSender - which should come from Chromium, but I don't have Chromium. what should I reduce the number of wakeups?– SergeyAug 21, 2011 at 16:57

Try with ethernet and wifi disconnected. Close all software. Look at powertop again. If the problem persist may be a bug in the kernel. Aug 21, 2011 at 20:16
