Last month I used 10 kWh. At .115 cents per kWh, I was billed $1.25 for electricity. I get a monthly $20.35 "facility fee" and 3% school tax, so the total bill is about $25.
Ready for SHTF lessons? (That's for my "under construction" house. Two LEDs on continuously, running the well a few times, charging a few drill batteries.)
Where we live, a January bill I have handy...(family of 8, super insulated 2400 ft, geothermal HVAC, well pump, electric water heater/stove/clothes dryer) 1,700 kWh.
And go to your main electrical panel, open the cover, tell me what amp is printed on the main (big, top) breaker. That will tell your max capacity, or is that ampacity?
