Beyond the mentioned "lots of energy use is actually gas for us", I think you likely have a bug in your calculations. Did you calculate this based on your expenses and back into usage, or directly from usage? (Or are you saying 100W per person?).

Unless you do not own a refrigerator, or have an incredibly tiny RV-style unit (36-50W!), you probably average 100W for your fridge alone.

Charging the devices you wrote your comment with is another 10-90W (when charging), and then your router is at least 5-10W continuously. Same thing with a television or computer monitor: pretty good when idle (<5 W) but likely high when in use (30+W for an efficient monitor, but more like 150+ for a larger television even if modern).

I don't see how your average could be 100W.
