2. Principles and assumptions of the intermittency model

2.1 Future configuration and model

Reflections on the energy transition are based on scenarios that describe developments over the coming decades in response to a forecast of consumption (which may fall, stabilize or rise) and define a shift in the energy mix (growth or decline in certain modes of energy production) according to environmental or other frameworks [BE 6 980] . Analysis of the input data enables us to characterize how the electricity mix will function in the configurations forecast by these scenarios, looking two or three decades ahead.
