One thing people need to think about is “How much power do I actually use, actually?”
Here in the PNW, PSE (Puget Sound Energy) has these nifty little charts that they print on your power bill. I have, over the last few years, significantly reduced my usage/bills by simply watching what’s on or off. For instance this last November, my usage was down about a quarter from the November last year. This resulted in about a third decrease in my bill, because you get a certain number of KWH at a cheap rate, then the rates zoom for KWH over a certain amount.
So LOOK AT YOUR BILL!!
My bill shows me using, pretty consistently, about 34-36KWH per day, wintertime.
Any plans for household generation capacity needs to target having that much capacity.
I have more than enough capacity for that using generators and/or inverters, but that depends entirely on the fuel supply.
