This article sure sounds foolish.  As I see it, the main driver in the
   increase in "growth"  (other than population) is productivity.
   Productivity tends to be driven by gradual adoptions of automation,
   which has been a major factor for 50+ years, and actually far larger.
   Automation isn't going away, and will only increase in effectiveness
   for decades
   Energy is a factor, but society is well on its way to the widespread
   adoption of solar and wind energy.  Solar is useful in most locations,
   and wind will eventually be useable just about everywhere, 24 hours per
   day, with the use of low-resistance materials to conduct that energy,
   for example metallic carbon nanotubes.  (MCNTs).
