Or maybe someone that had a similar issue that can help. Purchased this house last year and I was hesitant about it being all electric but we went for it. May-December were "normal" usages per google searches and were anywhere between 900kwh and 1400kwh. Jan-Mar have been 2700, 4300, and 4400 kWh respectively. WTF?! No I don't have a grow operation as that seems to be the first response per google. I run the AC way more than I do the heat. Majority of the house is LED. I run my work lights in the garage maybe 2hrs a day. I rarely weld.
I've checked the water heater coils as that came up a common thing as well. I would look into a home energy monitor but the chain stores only sell ones that monitor the two busses.
