17 Oct Energy Vectors

National Academy of Technologies of France (NATF)

Changes in energy procurement/uses have often followed differing ‘trajectories’ in different countries while being related by factors such as oil prices and climate change.  While these forces are still active, time-scales have shifted (e.g. for peak oil and gas). The Fukushima accident has recently shaken confidence into nuclear power.
This Report proposes a robust methodology helping in situations of energy transition to make relevant choices on both economic and ecological levels. Focussing on the French situation, it defines Energy Vectors as the support system delivering energy in the form of electricity, petrol, gas, or heat, etc. to consumers and deals with the intermediary stage of vectors between energy sources (coal, gas, U, wind, hydro) and demand of final energy (for transport, heating, industrial processes, etc.). But end-consumers are often not aware of the source for the final energy they receive. Distinguishing between sources would allow economic and ecological competition (when C02 emissions carry a price-tag).  This report throws new light on the political decisions that must be taken and provides guidelines with a long-range relevance – the parametric structure allowing application to any given case.
