Societies with access to energy sources with a large net energy surplus have an economic advantage over societies that use lower quality energy sources. A lower net energy means that more of a society's productive resources must be devoted to energy delivery, and thus cannot be used to produce nonenergy goods and services. It is the high net energy that has been available to contemporary society over the past several decades that has supported a powerful military, abundant food choices, growth of the arts, enabled modern healthcare, provided ample leisure opportunities, investment growth, retirement, and much more that is now take for granted.That's now changing.
