We crossed over the peak of that bell curve in 2016(peak oil), which makes sense if you think about our society since then, a slow decline..But, it is picking up speed...Some say 2018..Now if you look at barrels produced, it's easy to be fooled..But today, we count many bi products that were not historically counted before, and are not barrels of oil..But, it doesn't matter how many nuclear power plants we build, or if we crack the code of fusion energy.. The very worse thing that could happen is if humans found a free source of endless clean energy, because then the destruction to the planet would be complete, and there would be no chance of humans hanging on through a "dark ages" period for several thousand years as the environment recovers..Which is exactly what every "dark ages" period has been in our past..But, EROI is certainly one of the issues I was referring to... And has it's own built in consequences that are also unavoidable..And we killed 4.5 million people in the middle east because of those consequences, if you believe the report out of Brown University..There is a momentum/inertia to human civilizations, they don't change on a dime, ever..You have 8 billion people working very hard one way or another to keep the status quo, and you have a few million people working on the fringes to improve our practices, but too little too late.
