My ComEd electric bill arrived yesterday and I am thrilled. Well, okay, not thrilled, but I am doing the Happy Dance. (That link put a smile on your face, right?)
The billing period started June 10th, just a couple of days after I got the Solar Attic Fan, and is the first bill I've received since its installation.
When comparing my one month usage for the same time period last year, my electricity usage has DECREASED by 35.6%!!!!!!!!!!!
You are probably thinking, "Well, that's convenient Jessica, but Chicago has experienced a relatively cool summer this year with very little need for AC usage" and you'd be correct. The average daily temperature from June 10th - July 11th, 2008, according to my ComEd bill was 72 degrees. During the same period in 2007, the average daily temperature was 74 degrees. Not a significant difference.
My Solar Attic Fan has produced significant savings for me in one month! Yeah! Great for Mother Earth and great for my wallet! Thanks Dave!
