Regardless, my curiosity is keenly engaged when I see that the rejected energy EXCEEDS the energy services - and not by an insignificant amount. This means that energy released is greater than that we receive from our efforts. The definition' taken from LLNL's report:
" ... is the division between “useful” and “rejected” energy based on estimates of conversion efficiencies in the various end-use sectors. “Rejected energy” consists primarily of heat losses. Conversion and plant losses at electric utility generation stations that burn fossil fuels are a matter of record, but inputs to total transmitted electricity such as nuclear and geothermal power, are associated with estimated efficiencies of the conversion process to electricity. These estimates vary from 90% in the case of hydroelectric power to 18% for geothermal energy."
Below are the diagrams for 2008 and 2011. In each example more than 40 Quadrillion BTU's are received in energy services > while more than 50 Quadrillion BTUs are lost, released and ... essentially wasted. If our capital systems worked that efficiently, we'd already be broke ~ wait - maybe there's something to that thought?!
Regardless, there has to be a better way ~ particularly in light of the significant challenges we see with modern society and the likelihood of continued growth by both developed and undeveloped nations.
