The problem with running out, whenever it happens, is that if the world is anywhere near as reliant on fossil fuels at that point as we are now, it’ll cause an epic economic collapse. As fossil fuels grow more and more scarce, prices will skyrocket. That will cause a furious rush to develop renewable energy technology, but it may be too late at that point to prevent a worldwide economic meltdown.
Basically, we’re currently living off of a trust fund we found underground, and we’d better learn how to get a job before it runs out.
For our sum-up for this section, how about:
At some point in the future, either really soon or just a little soon, we’ll have no choice but to stop running everything on fossil fuels, because they’ll either be gone or too expensive.
This statement highlights the fact that we’re very much in what will be known as the Fossil Fuel Era of human history.
Bringing back our first statement—
if we continue to burn fossil fuels as much as we are, things might get really shitty kind of soon—suggests that if we continue to dick around in the black zone until we’re forced out by short supply, we’re risking making the yellow zone permanently worse for humans to exist in.
This is why Elon Musk likes to say that the indefinite extension of the Fossil Fuels Era is “the dumbest experiment in history.” He emphasized this point to me: “The greater the change to the chemical composition of the physical, chemical makeup of the oceans and atmosphere [due to increased carbon emissions], the greater the long-term effect will be. Given that at some point they’ll run out anyway, why run this crazy experiment to see how bad it’ll be? We know it’s at least some bad, and the overwhelming scientific consensus is that it’ll be really bad.”
In other words, as it relates to the above timeline—there’s potentially huge long-term downside to staying in the black area for too long, so let’s just get ourselves to the yellow part as soon as we can.
