Query: Uses a lot of electric

I had to return mine because it uses about $20 worth of electricity per week. I was afraid it was using a lot of electric because it was creating a small amount of heat as it was running. Then when I got my bill, I knew for sure. I hadn't been doing anything else differently as far as electicity usage goes. It does take a lot of humidity out of the air but I cannot afford to run it.
