How to optimize the spectrum: The oil experience

Since several years, sustainable development (SD) has become an important issue in many technical domains. One of the main contributors in CO₂ emission is undoubtly petrol engine. This explains why car industry was the first interested in finding solutions to decrease oil consumption and to optimize car usage. Starting from the idea that spectrum is a natural and public resource which should be carefully used and shared, in this paper we apply to spectrum usage at every levels (standards, equipments, usage, etc.) analogies coming from oil experience.
