Power usage of the core

[Olberd]

Does any of you know how much electricity a typical core uses during heavy, normal and idle usage?

What experience do you have with saving power on the core (standby or shutting down during nighttime or such).

98% depends on your hardware (cpu, mainboard). today, the hardware is built to consume not so much energy.

Yes, it's dependent on the hardware and on usage.

I'm looking for a lower bound on electricity usage.
Has anyone measured their core's idle power usage or any?

What experience do you have with saving power on the core (standby or shutting down during nighttime or such).

I am interested in this as well. I understand that the core is meant to be up at all times, however I am going to use it mainly as a media centre for now. No need to keep it running at full blast while I am sleeping .  Based on my experience with various distros, I know that power management can be a little tricky...
