techtom, I would suggest putting in the inflation rate of Fuel and Electricity over the same period. I did some online research of both of those and found it to be 6.55% per year compounded for gas (I looked at a 20 year and 40 year range of data) and then for Electricity it was 0.83% per year compounded. When you do the math with energy inflation it is even more amazing. I even did a what if, took a year when the electricity went up 10% to simulate a clean energy plan like clean coal etc. And the VOLT still just got better with time.
Food for thought.
