In an electronic computing circuit, all the energy delivered by the electric power supply is converted into heat (dissipation). A result from Bennett in 1973 showed that the minimal amount of dissipated energy is not linked with the time-complexity of the computation, but rather with the size of the result, which can be very low. However, real chips are dissipating proportionally to the time-complexity, and this is the major problem challenging the increase of performance and the miniaturization of mobile devices. Why are we confronted to this contradiction ? We return to the reading of Bennett's paper in order to look for a renewal of fundamental questions it can rise. We suggest a link with the nature of time and with synchronization in distributed systems. This text is a transcript of the talk given at the MIR seminar (Mathématiques pour l'lnformatique et les Réseaux) in ENST, the March 9th 2006.
