Seriulsy, POC's don't 'idle' - they are either more or less shut down
with teh clock stopped, or running at teh same curent they always run
at.

Not correct. The standard transistor types in a computer consume power when
switching to overcome latent capacitance, but have low quiescent currents
when not doing so. Modern computer equipment is specifically designed to
slow down and avoid switching unnecessarily, meaning that power consumption
drops when nothing much is happening. The power consumption drops markedly
when you have idle CPU cycles.

It isn't like the old TTL logic, where the has to be constant current flow
through a resistor, making the power consumption pretty constant, or related
to state.
