This for lack of having asked the right question: "should we replace oil", in other words is it simply the means that is harmful, or more fundamentally its purpose.
The finality, the progress animates the man since more 2 millions of years !!
There are 2 millions of years, the first stone tools, leaving piles of cut stones (first destructions of the environment), already a barter of these stones transported very far, and since incessant progress, which made increase our brain, fire there 700000 400000 years, already big action on the environment (disappearance of very large animals especially in Australia, there are 40000 years), art, paintings on rocks there 35000ans, the trade or barter of various stones, flint, obsidian, the discovery of agriculture and breeding, there is 10000ans, with incessant acceleration of progress, which allows the multiplication of the population (max there is more than 10000ans, less a man at Km2 !!) and now much more than 100 / km2, thanks to this progress and especially to the medical, as aseptic 1840, almost nothing, but hyper effective, to lengthen life! It is impossible to suppress this progress which multiplies the population, unless to be criminal !!!
So it's impossible to stop this progress in its best formno one wants to come back to the caverns, (10 to 13 ° C even during very cold weather), nor to the coarse fires of wood, nor to suppress the oil (plus a single indispensable plastic pipe, which lacked the time of Louis 14, with instead of toxic lead !!
It is therefore necessary to improve progress, by suppressing its most harmful effects, but it is impossible to ignore or deny this progress in what is most effective, and we must adapt and correct its harmful effects!
The energy will continue (1000 times more energy than human for the same price as before !!) with any means, simply it will be necessary to block economically, rather than by force or by catastrophes, the harmful effects like CO2, and use the sun and wood stoves (non-zero pollution).
The sun provides us with this free energy, very in excess, just use it well!
Oil and fossil fuels are a form stored spontaneously for almost a billion years by the earth, and therefore in huge quantities, able to burn many times all the oxygen in our atmosphere!
It is enough to continue to store in a controlled way the heat and the solar energy without destroying the terrestrial atmosphere with the C02 and without burning all the breathable oxygen (possible on a few thousand years at the current rate much higher than its speed renewal, linked to the natural disappearance of CO2)
We begin to regulate our population that will not exceed 9 billion !!
