Burning Money . . . by Wasting Energy

If you have ever wondered how much energy is wasted in the United States, then look no further than this chart from the Lawrence Livermore National Laboratory.
US Energy Flow Chart 2011What your are looking at here shows how many Quads (Quadrillion BTU’s) of energy is produced from each source of energy . . . and how much is wasted through inefficient processes or simply lost as heat energy.  In 2011 more than half (57%) of the energy produced was rejected.  In terms of electricity generation, almost 2/3 of the potential energy is lost.  Cogeneration plants achieve a much higher efficiency level than conventional coal or natural gas plants.  In the transportation sector the efficiency ratio is even worse with only 25% of the energy produced actually being used.  If there are any entrepreneurs out there, I see many opportunities for improvements here.  In fact, I think this chart could show the next trillion dollar opportunity!
