       |  _The Scale of Stored Energy_
       | 
       | The geological process of fossil fuel formation represents an
       | almost incomprehensible concentration of ancient biomass. The
       | energy density that powered the Industrial Revolution and modern
       | civilization is a direct result of this multi-million-year
       | process of collection and compression. An analysis by Carnegie
       | Science provides a stark quantification of this energy subsidy:
       | to produce the precursor organic material for a single U.S.
       | gallon (3.8L) of gasoline required approximately 90 metric tons
       | of ancient plant matter. Scaled up to a global level, the numbers
       | become even more staggering. The total amount of fossil fuels
       | burned in the single year of 1997 was created from ancient
       | organic matter containing 44e18 grams of carbon. This is more
       | than 400 times the net primary productivity (NPP)--the total
       | amount of new biomass created through photosynthesis--of the
       | entire planet's current biota, both terrestrial and marine, in a
       | year.
       | 
       | This reveals a fundamental truth about our energy system:
       | industrial civilization is not running on a "current account" of
       | solar energy, such as that captured by modern plants, solar
       | panels, or wind turbines. Instead, it is liquidating a vast
       | capital reserve of ancient sunlight that the planet took
       | geological eons to accumulate. This also explains why these fuels
       | are, on any human timescale, non-renewable. The specific
       | conditions and immense time required for their formation mean
       | that the Earth is not producing any significant new deposits. We
       | are, in effect, draining a finite reservoir.
