7. Conclusions

An analysis of the properties of wind power and solar photovoltaics based on the most recent actual data on wind power production in France and Western Europe, and solar power production in France, combined with an assessment of the consequences of implementing the ADEME 2030 scenario, which has clearly inspired the energy transition bill about to be presented to parliament, leads us to the following conclusions:

  • there is no correlation between wind generation, which is random in practice, and consumption. The partial correlation between the latter and solar production covers only part of the active day;

  • the planning of complementary generation resources cannot be based on a guarantee of supply from these intermittent energies, which are variable throughout the year (a factor of 5 on the scale of a few days)...
