I think a bunch of 500 W+ votes have misunderstood the assignment. Looking for minimum consumption, not average. So what your house consumes 24/7, through the night, and even if you're not at home. Fridges are in, automatic lighting, CCTV, servers etc. are all in, but not aircons, and arguably not geysers or pool pumps. Definitely not ovens.
Our base load is 60-70 W. About half of that is the fridge (a bit higher in summer when the duty cycle is longer). Of the remaining 30 W or so, about two thirds is the Raspberry Pi, router, ONT, camera, and mini UPS. The last 10 W must be TV & PC standby, and that little red neon light on the multiplug.
