$this->bbcode_second_pass_quote('Reverse Engineer', 'T')hat might be when the model has 95% of the available energy gone from oil, but it by no means represents when the end of the contraction would be in terms of population, that will go on for quite a while longer, unless you postulate an immediate die off within 16.3 years?
The
Available Energy model is a rigid mathematical representation of the world’s petroleum supply, from an energy perspective. Some where around here is a list of it limitations. It does not include the effects of NG or coal depletion, nor does it anticipate any Black Swan events.
It is intended to be used as a frame work to estimate the cause and effect of energy degragation from petroleum supplies, and produce a usable time table. Since the relationship between available energy and economic activity is well documented, it gives us a view of the society’s future economic state.
From a historical perspective the decline in world population will probably be dramatic and swift. We know that economic activity affects population growth and density, especially in temperate regions. How fast that depopulation occurs, is however, outside the model’s ability to predict. What we do know is that the energy from petroleum is essential to the support of the world’s population. From this point going forward that energy will be declining rapidly (geometrically), and for all practicable purposes that energy will no longer be available in 16.3 years.
From an analysts point of view, the model is infinitely superior to the “dried bones” and “chicken blood” approach used by contemporary economists, which can not be used to establish verifiable boundary conditions. The thermodynamic approach can. If I were to bet my life on it (which I am) I would prefer a model founded on thermodynamic principles rather than the witch craft presently practiced by neo-classical economics!
