Citrus responds abruptly:Should we really try to replace oil?
whereas in its preamble, as well as inside the question (really) Ulysse88 explains that the answer is not so obvious and that it would be useful to ask further questions.The answer is yes, as for nuclear.
Unless, of course, I have not understood anything in his text, he explains that oil has provided us with abundant energy that has considerably modified our possibilities, facilitated our lives by satisfying unimaginable goals and desires in other ways (hence the reaction of Citrus).
But, at the same time he is aware of the damage caused by this addiction: the loss of our humanity. I pass this consideration before the degradation of the environment to insist that the two destructions are concomitant and that it is not without reasons that only the environment is put forward by the dominant thought.
So, the replacement of oil by another resource is absolutely not the priority, because energy is not a solution but rather the problem!
