Abstract: Lifestyles and social structures have a significant impact on energy consumption. Governments are focusing their strategies on renewable energies for energy supply and on energy efficiency to reduce energy demand, but energy transition is strongly linked to wider societal change. By creating prospective energy scenarios, the aim of this research focused on energy sufficiency was to evaluate, using data models and assumptions, the energy saving potential by changing lifestyles, habits or collective organization. A theoretical approach on energy sufficiency was proposed and two scenarios have been realized in order to evaluate energy-saving potentials under various visions and trajectories. Results show that energy sufficiency allows reducing energy consumption from 26% to 40%. Regarding to energy challenges, sufficiency contributes to increase local resilience. Sufficiency could either speed up and/or raise energy transition governmental targets.
