    These graphs - Energy Flow - are very interesting and put our overall energy generation and energy use in perspective (click on the graphs to enlarge them).

    What I find really shocking about this chart (from Lawrence Livermore Labs), is that of the 97.4 quads of energy inputs to the system, only 38.4 quads (39%) provide useful services. Huge losses in both electric generation and transportation. Kudos to those who drive EVs powered by PVs!

    Had to lookup the Quad unit of energy. Wikipedia says it's 10^15 BTU or 293,083,000,000 Kilowatt-hours (kWh) or 33.434 gigawatt-years (GWy). Never heard the unit GWy before, but me likey. :)
