Wow that is high…Are you in CA? The things I have learned to do are make sure the refrigerator stays full or turn down the temperature. When the frig is fairly empty it takes more electricity to keep things cold. Old refrigerators use a lot of energy
Another thing I did when I thought my bill was crazy..I found out I had radiant heat and I turned heat off at the breakers, otherwise it continues to run.
I also asked that they send me the instructions to read my own meter. I have found the meter person making mistakes in the past. Turn off computers and watch your consumption of electric appliances. Wash clothes once per week only…(I’m in a house with more than just myself and that is a strict rule). I also hang dry most of my clothes if possible.
But, you do know they will come out and do a free assessment for you…
Just my 2 cents
