The energy equation
is simple, but few, it seems, understand it.
It is about the amount of energy expended, or investment, to
achieve return on that investment – it’s about energy returned on energy
invested (EROI).
And of course, since the agricultural revolution, an effect
accelerated when we understood how to exploit fossil fuels, we have replaced
human energy with the immensely energy-rich fossil fuels and built a way of
life that is clearly unsustainable.
Writing on “Our Finite World”, a member of the American
Academy of Actuaries, Gail Tverberg, who is also an M. S. from the University of Illinois,
Chicago in Mathematics, fears for the collapse of society.
Her latest piece: “Diminishing returns, energy return on energy invested, and collapse” helps us understand global financial dynamic is
unfolding.
In conclusion she says: “We cannot simply go backward, because methods
that worked in the past, such as using draft horses and buggy whips, will no
longer be available without a long development period.
“We are truly facing and unprecedented situation – on that is very hard
to prepare for”, she writes.
