Investment Success


Last August, I replaced all the window sashes in my house, and I am pleased that my electric bill has been less each successive month, and the outside temperature has not varied significantly from the previous year.

It has been a mild Spring so far with cooler temperatures. The true test of the windows will be in late July, August, and September, so I am curious to see what this summer's bill will show.

So far, I am very pleased with the return on my investment.

September 08 - 110 kwh (avg daily temperature from previous year -4 degrees)

October 08 - 62 kwh (avg daily temperature from previous year -1 degree)

November 08 - 80 kwh (avg daily temperature from previous year 0 degrees)

December 08 - 383 kwh (avg daily temperature from previous year -9 degrees)

January 09 - 844 kwh (avg daily temperature from previous year +10 degrees)

February 09 - 452 kwh (avg daily temperature from previous year +7 degrees)

March 09 - 21 kwh (avg daily temperature from previous year +8 degrees)

April 09 - 22 kwh (avg daily temperature from previous year 0 degrees)

May 09 - 213 kwh (avg daily temperature from previous year +1 degree)

Kilowatts saved in nine months = 2,187

  2. Glad your investment is paying off. By the way, how hot does it get there usually? This week in North Texas, we are looking at highs of at least 103-104. It is too hot to do anything outside at all. Blessings to you -
