Attic Foil seems to work

Since I installed radiant heat barrier foil in my attic my electricity bill has gone down. Compared to the same month last year I have used 14% fewer KWH. In giving the foil credit for the savings I am assuming all other things are equal such as AC, applicances usage etc. I saved $21 dollars the first month I installed the foil. At this rate I will get full ROI in 7 months. Nice.
