However, the thin oil should lead to an increase in prices, which in turn should limit consumption to the profits of alternative energy sources, fossil fuels (coal, etc.), or renewable. All things considered, it is reasonable to think that we have about 50 years of oil. Remains to be seen at what price ...

It took a century for humanity to consume half of the oil, it will take more than a half to fully deplete the reserves.
