Wow, that is really low. I know an elderly woman who lives by herself in a small house who brags that her bill is just over $100 per month, so she would be impressed with that.
LED lighting, well-insulated HWC, no power-guzzling devices running 24/7, we don't go out of our way to save power but you can live fairly cheaply without missing out on anything. Just checked the last power bill and it was $58. In the winter it goes up to about $70 due to the heat pump.
