Dead wrong. It is absolutely certain that the world will run out of fossil fuels sometime in the near (in historical terms) future. That's just basic science and simple math: there's only a finite amount down there, the creation rate is infinitesimally slow, so eventually you get to zero. (Of course it will become economically impractical to use for fuel before then, as recovery costs rise.)

And it's strange that nobody has actually challenged the sheer number of abandoned wind turbines that currently exist. 14,000?

OK, I challenge it. Where are they? Unless you are counting all those turn of the 20th century Aermotor water pumps sitting on ranches, or (like my neighbors' one) kept for purely decorative purposes.
(If nothing else, those wind turbines probably contain a lot of copper. In a world where people will try to cut down live high-voltage power lines to sell as copper scrap, they aren't going to be there for long.)
And for counterpoint, how many abandoned oil wells and coal mines are there?
