U.S. Energy Flow, 2005 (Quads) U.S. Energy Flow, 2005 (Quads) 5  85% of primary energy is from fossil fuels; 8% is from nuclear; 6% is from renewables.  Most imported energy is petroleum, which is used for transportation.  The end-use sectors (residential, commercial, industrial, transportation) all use comparable amounts of energy. http://www.eia.doe.gov/overview_hd.html

16. Exponential Growth/Decay Time rate of change of X is PROPORTIONAL to X itself “ y Proportional to x” => y=rx (r is a constant) For our case here: dX/dt=rX (if you like calculus) Solution to this is: X=X o e rt ln(X) = ln(X o ) + rt

18. A subtle point “Annual compounding” is not the same thing as “continuous compounding”, so you have to be a little careful with how you discuss annual growth rates. True exponential growth with a rate of 7.5%/yr for two years gives an increase of: X=X o e 0.075/yr*2yr =1.162*X o An “annually compounded” interest rate of 7.5%/yr gives: X=X o *(1.075) 2 =1.156*X o i.e. e 0.075 is not exactly equal to 1.075 (it’s really 1.07788, so it is slightly bigger). The difference between the two cases is greater if you consider greater periods of time.
