Our electric bill went up this last month despite moderate temperatures. Typically, mid-summer goes up because of the air conditioning but we have not used it very often and I was upset to see that our bill went up anyway. I said something to my husband and he is sure he knows why. He said it’s the ceiling fans! Each of the 4 bedrooms has one and we had a bad habit of leaving them on even when no one was in the room. I’m sure someone knows the statistics of how much you save by not using them but I don’t. I just believe my husband. Give it a try and see if you notice a difference!
