Abstract Information on the energetic balance in active regions derived from space observations is reviewed. It suggests both a global balance with some lag between sunspot darkening and plage brightening and the existence of a solar-cycle modulation. Some recent models are quoted. Recent works on the role of the global magnetic field topology and on flare energy storage are briefly discussed. The role of large scale structures is emphasized. Progress on the understanding of the energy transport mechanisms in solar flares is reviewed. It includes new observational indications of the existence of low energy protons and confirmation of the significance of the coupling between modes to the transport of energy. The role of the radiative transport mechanism is underlined. Observations support for the model of chromospheric evaporation derived from multiwavelength observations is presented. Other possible interpretations are briefly discussed.
