Energetic footprint of quantum coherence and entanglement, irreversibility of quantum measurement and decoherence are typical research topics in the field. By staging simple interacting systems like atoms and photons, quantum optics provides a convenient scenery to study these effects. In this talk I will present a new framework to analyse energy and entropy exchanges in quantum optics, and apply it to elementary mechanisms: spontaneous and stimulated emission, coherent driving, driven-dissipative dynamics. I will showcase a few recent experimental results to illustrate the operationality of this framework before concluding on the impact of this research on the energy cost of quantum technologies.
