Thinking about my home (in the UK) the "worst offenders" seem to be things that heat things, washing machine when it's heating water (~2.5kW), electric oven (~2-4kW), kettle (~1-2kW), electric heater (1-2kW).
Outside of those, we could have most other things on in the house and not be using much more than 1kW, though granted I've been very intentional with electrical efficiency with the electrical and electronic devices in our home (by UK standards).
Heating is always the culprit (or cooling but that's less of an issue in our area).
But one thing to realize is that the industry was just lazy and none of this is actually "needs" a full electric line.
- You don't need actual heat for washing clothes if you using washing detergent. There are no real simple "machines" available as far as I know, except simple camping washing machines
- A rice cooker can work from as low as 250w. I have a "cooking" option in mine drawing 500w taking no longer than the usual 2000w plate (better isolation, optimized heat transfer, ...) to get water cooking.
- Heaters are difficult, I've tried a lot of electric options and they all draw a lot of power when you heat something like 20°C over the outside temperature. However ex. "Ecomat 2000" (small ceramic heater) can easily heat a average room at 450 watts.
One way to get warm and way lower wattage is heating blankets. From 50 - 100w usually on for 50% you get very far with little power.
Not sure if that helps anyone. But I spent a lot of time researching efficient caravan alternatives.
