18 Oct Vectors of Energy
National Academy of Technologies of France (NATF) 2011
This extensive study is the follow-up of the NATF October 2008 report “Prospective for the Energy in the 21st Century”.
A vector of energy is a system of the primary energy distribution to the final consumer. A vector of energy stage is intercalated between primary sources (carbon, oil, natural gas, uranium, hydraulic, wind, solar, biomass, geothermal) and the stage of consumer needs (transportation, heating, air conditioning and multiples electricity uses…). The report does not propose the scenarios but is a sort of a guide for the most efficient use of various energy sources for a given application, from the economic and ecological point of view. Numerical application of the method allows taking into account and simulating present and future evolutions of various sources of energy costs and of the price attributed to CO2 emitted. An analysis of sensibility of these parameters is also included.
