Our electricity bill swings between $140 and $488 a month. Seriously! There is no pattern I can discern, even with the help of the electric company's tool that allows me to compare with any day or month and any year. It also shows the temperature for the days compared. So, lots of information, but nothing makes sense. Unless they're just pulling numbers out of their corporate butt. I am asking for any tips for lowering the electric bill and I'm asking if anyone can make any sense of this wide difference every month. We do roughly the same things when we're home, so there should not be such a huge difference from month to month. I'm also posting 3 months worth of usage graphics which compare to the same time the year before plus the temperature. I do appreciate any insight anyone might have. In April, it was 1620 KwH, or 49.09 KwH per day for 33 service days, with an average cost per day of $8.16 for a charge of $269.12 for the month. In May, it was 1285 KwH, or 44.31 KwH per day for 29 service days, with an average cost per day of $7.49 for a charge of $217.20 for the month. In June, it was 955 KwH, or 30.81 KwH per day for 31 service days, with an average cost per day of $5.65 for a charge of $175.16 for the month.
