My bill also shows I use way more electricity than similar houses. My best guess is they have a heat pump or gas heat/water heater. Whereas I have forced air electric.
I recently installed an emporia energy monitor. It’s basically a kill-a-watt meter that you connect to the circuit breakers for full house monitoring. And while I see some areas that I could improve to cut my bill, no where near enough to get to what the power company is saying similar houses are using. Saving up for a heat pump now as I think that’s the best thing I can do to get my bill down. And as a plus I’d have central AC instead of having to use window units in the heat.
