We are all electric, 3000 sq ft plus pool and shop with two freezers and extra fridge running. 2 central units with heat pump and ac. We have a wood burning fireplace with insert if the power goes out. Our electric bill has been under $200 for years. Our house is very well insulated. The guy who built it had double outside walls built with air gap or something like that. It was his could live off the grid house if necessary. He was adding solar panels when he died so they never got installed. We opted not to have them. Once heated or cooled it stays that way for a very long time. No gas bill. The guild members that use natural gas are saying how their heating bill has doubled and some even tripled this winter.
