Economics of Oil and Fruit Roll-Ups

In the first grade, my favorite part of my lunch was Fruit Roll-Ups.  My Mom used to call them fruit road kill, but to my first grade taste buds they were a gourmet fruit treat.  I quickly learned that my consumption of fruit rolls ups could not exceed my supply.  I had two primary supply sources of Fruit Roll-Ups:

  1. domestic supply from home:  those Fruit Roll-Ups that my mother purchased and put into my Spider-Man lunch box.
  2.  

  3. non-domestic supply: those Fruit Roll-Ups that I gained from other sources, primarily through purchase or barter transactions with classmates.
  4.  

Obtaining Fruit Roll-Ups up from sources other than my Mother was expensive and unreliable.  When supply for barter was available I would offer a cookie for an orange flavored fruit roll up or my place in line at the handball court for an apricot fruit roll up (my favorite flavor).  My Mother’s nurturing nature made domestic supply the most stable source of Fruit Roll-Ups.  I could rely on that one Fruit Roll-Up to always be in my lunch box.  I understood at a young age the hazards of upsetting my Mother, who among countless other things, could affect a disturbance of my stable domestic source of Fruit Roll-Ups  I knew that if that source was upset I would need to work hard to increase non-domestic supply or inevitably reduce consumption. Stated in its most simple terms, my consumption of Fruit Roll-Ups could not exceed my supply . Given that: CFR =  my consumption of Fruit Roll-Ups FRmom = Fruit Roll-Ups supplied by my Mom FRclassmates = Fruit Roll-Ups obtained through barter with classmates Then: CFR = FRmom + FRclassmates I learned this simple truth of the relationship between consumption and supply at a young age.  And every day as an adult I deal with the economic reality that my consumption of the things that I need or want cannot exceed my supply.  If one source of supply of anything I desire diminishes, I have no choice but to find a way to increase supply from other sources or reduce consumption.  The Fruit Roll-Up analogy might have been a long winded method to summarize this formula, but something inside of me just felt like blogging about Fruit Roll-Ups today. This same rule of supply and demand applies to our nation’s supply and use of oil.  The nuances of the economics of oil are substantially more complicated that those of Fruit Roll-Ups.  Oil supply and demand is impacted by a variety of domestic and global economic, social and political factors.  While these factors may resemble school yard economic, social and political factors, they are more complex if for no other reason than because of the amount of money and people involved.  But the fundamental restriction that consumption cannot exceed supply holds true. ((ignoring the impact of stock piles or borrowing.)) Continue reading “Economics of Oil and Fruit Roll-Ups”

Energy Storage: From Gasoline to Ultracapacitors

Energy cannot be created or destroyed.  Scientists have accepted this theory of conservation of energy for ages[1].  But this theory seems to be in juxtaposition with the conventional thought of energy being a scarce resource.  If energy cannot be created or destroyed, why are we always scrambling to find new sources of energy?  While energy cannot be created or destroyed, it can change form.  And there are only certain forms of energy that we can practically harness for use.  One of those forms is potential energy[2].  How we work with potential energy, transport it and harness its potential, is an area of significant evolution in science.
