There are 1.65 trillion barrels of proven oil reserves in the world as of 2016.
The world has proven reserves equivalent to 46.6 times its annual consumption levels. This means it has about 47 years of oil left (at current consumption levels and excluding unproven reserves).
This means that the oil is going to run out in our lifetime

Update: It is infact not true (or just partially true), because it only considers already known oil reserves that can be pumped out with current technology.
There is more oil that can potentially be used as technology and infrastructure advances, so the estimate of 50 years is wrong.

No, I think quite the opposite. I learned this recently and I was quite surprised no one ever uses this as one of the arguments for renewable sources of energy.
Because why invest in an industry that is basically declining and wouldn’t be around after 50-60 years.
People have been using this as an argument for renewables since what? The 70s oil crisis? As new ways to access hydrocarbons got discovered the horrified realization was that there are plenty of reasons to bail on those faster than they run out, unfortunately. The issue isn’t that we’ll run out, it’s the amount of damage we’ll cause until that point.
And also, it’ll take much longer to run out, but others have mentioned that already.
This thread is interesting to me mostly as a periodic reminder that culture wars have shorter memories than one would think. People forget hotly contested issues and the public opinion battle lines around them at a horrifying pace. You’d think it has to do with old people dying and new people growing up, but it’s a lot faster than that.
It’s because it isn’t true. We don’t go looking unless it’s needed.
