Les consommations d'énergie dans le monde : une méthode robuste de prévision de leur évolution à moyen terme ; premières conséquences

This document proposes some ideas on the global energy context in an anthropogenic view: what are the needs in energy for the world population? How could they be satisfied in the middle term? What links exist with the near future of a necessarily limited system, the ‘Earth Surface, oceans and atmosphere’ system? Over past 30 years, the world individual energy consumption has been a constant. This is the basis of a robust method for predicting, in the short and middle term, the relative part of the main energy vectors and their interactions with the carbon cycle. Finally, some essential aspects of any energy planning are pointed out. To cite this article: M. Combarnous, A. Prieur, C. R. Geoscience 335 (2003).
