The belief that it is possible to have a perpetual "economic growth" based on fossil energy has been challenged since the 1970s. However, only in the last decade is this issue re-emerging once again because of the predicaments of climate change and peak oil. Many, finally start to perceive that an "economic degrowth" entailing a downscaling of the current size and pattern of socio-economic systems seem unavoidable. In this paper we analyze the implications, the feasibility and the desirability of possible trajectories of downscaling from an energetic perspective.
