Quelques extraits :
"The assertion that we are likely to run out of resources is a re-run of the "Limits to Growth" argument (Club of Rome 1972 popularised by Meadows et al in Limits of Growth at that time
[oups, je crois que c'est nous la...]. In the decade following its publication world bauxite reserves increased 35%, copper 25%, nickel 25%, uranium and coal doubled, gas increased 70% and even oil increased 6%.) fashionable in the early 1970s, which was substantially disowned by its originators, the Club of Rome, and shown up as nonsense with the passing of time. It also echoes similar concerns raised by economists in the 1930s, and by Malthus at the end of the 18th Century."
"
Historic data show that the most commonly used metals have declined in both their costs and real commodity prices over the past century. Such price trends are the most telling evidence of lack of scarcity. Uranium has been a case in point, relative to its late 1970s price of US$ 40/lb U3O8."

hihihihi
"world copper reserves in the 1970s represented only 30 years of then-current production (6.4 Mt/yr).

Many analysts questioned whether this resource base could satisfy the large expected requirements of the telecommunications industry by 2000. But by 1994, world production of copper had doubled (12 Mt/yr) and the available reserves were still enough for another 30 years. The reserve multiple of current production remained the same."
Attention la c'est pas mal :
"Another way to understand resource sustainability is in terms of economics and capital conservation. Under this perspective, mineral resources are not so much rare or scarce as they are simply too expensive to discover if you cannot realise the profits from your discovery fairly soon. Simple economic considerations therefore discourage companies from discovering much more than society needs through messages of reduced commodity prices during times of oversupply. Economically rational players will only invest in finding these new reserves when they are most confident of gaining a return from them, which usually requires positive price messages caused by undersupply trends. If the economic system is working correctly and maximizing capital efficiency, there should never be more than a few decades of any resource commodity in reserves at any point in time."
Ils savent ce que c'est que l'EROEI ? hahahaha
Le graph qui suit est très amusant, comme le reste d'ailleurs. Jetez y un petit coup d'oeil, ca met de bonne humeur! Merci messieurs, je vais pouvoir dormir tranquille! Bon, et bien je crois qu'il n'y a plus qu'à fermer Oléocène. Et oui, les réserves augmentent lorsque les prix montent et ces réserves ne sont jamais importantes car sinon le marché s'effondrerait. Elles augmentent en fait simplement avec le temps pour rester à valeur fixe. Haaaaa, quel soulagement! Moi qui me faisait du soucis pour l'approvisionnement énergétique futur, je me sent la d'un coup beaucoup plus léger! Merci beaucoup ! Bonne nuit à vous tous!
Je comprend maintenant enfin pourquoi ils construisent tant de nouvelles centrales. Youhouuuu, je comprend aussi nos députés maintenant

Vive l'EPR !
