My electricity bill has been climbing up in recent months, up by 20%, to
40% and now doubled. There have been no appliance change and I didn't turn on A/C. So, it's quite puzzling as to why the electricity bill has doubled.
I can think of two things: 1. meter malfunctioning or 2. appliance malfunctioning. Before I tackle the meter malfunctioning, I'd like to know if appliance is at fault. I don't see any appliance running non-stop. Could appliance somehow increase its electricity usage? How?
I have an electric water heater, one full-size and two half-size fridges, electric cook top, ceiling fans, a swimming pool pump, a small oven, plus lights. That's all.
I have GFCI. So, current leaking into ground is not a problem.
