What, if any, is the relationship between bandwidth and power?

Is there any fundamental physics relationship between the bandwidth of data transfer (i.e., number of data per time) and the minimum power (i.e., watts) required to sustain such a rate over a given amount of time?
Obviously there are macro-scale power requirements for something like the internet, but that's not what my question is about. I'm wondering about the theoretical limit, if there is one. It seems like there would have to be some minimum amount of power required to move a bit of information from one place to another. Are there papers or research I can read on this topic?
