My last bill was to July 13th & was $139.00 for 1,500 sq.ft. I'm totally electric, so not too bad. My neighbors bills are twice as much as I'm really conservative - nothing plugged in that is not being used. Air conditioning on 77 during the day & 75 at nite due to 2nd floor. Our electric rate are going up probably 20-30% this year & this is the 1st yr. we can shop for electric suppliers.
