Right. Humans will be cooked off the planet long before we can get it
all out.


Quite literally as it happens. At the historic 2.3% annual petroleum
usage increase rate, in 400 years the waste-heat alone will raise the
surface temperature of the earth to 100 C (212 F). Simple arithmetic
(exponential growth) and physics.

But we have about 40 years of proven reserves at the current rate
of use (and given the 2.3% increase in usage, it's more likely to
be much less than that).

And long before that 40 years arrives, the costs of extraction will
balloon, and the costs to the consumer will be huge due to scarcity.

If we wait that long to prepare alternatives, we won't have enough
energy to both support current needs and to prepare for the future
(the energy trap).
