(I just switched it to always on. Trying to optimize water heating timing was just preventing it from storing solar electricity as heat, and didn't change daily energy consumption much.)
Edit: I should add we almost exclusively use a dishwasher to wash dishes (< 4 gallons a day). Laundary is probably our main water consumer. Showers have High Sierra shower heads. They're inexpensive, strong stream; 1.5 gpm (5.7 LPM)
I recently found a 100 watt phantom load (after the 30kWh measurement), and now the house idles at 500w. That includes fridges, water treatment + water heating, internet, LAN, NAS, etc).
I plan to put the synology on a timer.
Early in the pandemic, we had a period where it was unoccupied but not really shutdown, i.e. refrigeration continued and lights were on timers for security. I can call this the baseline/idle load. It was about 9.2 kWh per day and 0.3 therms per day of natural gas for the pilot lights and tank-based water heater. When occupied in mild weather, our baseline moves to about 10.2 kWh per day and 0.5 therms of natural gas with cooking and water heater usage.
Our peak highest usage for electricity seems to be about 13.2 kWh per day in a summer month with terrible AQI where we had filtration fans running and even deployed a portable A/C due to not being able to do our normal natural cooling of the house. Our peak natural gas usage was around 5.2 therms per day for a cold winter month.
Edit to add clarification: these are averages over a 1 month billing period, not instantaneous peak power etc. When looking at finer grained usage, our electricity is quite flat over time with weekly spikes when we run our laundry and dry clothes with electricity.
My thoughts exactly. Without any cooking at all (and exluding heating) we would do like 2.5kWh/day. But add a morning coffee (drip), noon thea (boil with induction), and a nice dinner to that (at least 2 induction plates, often oven as well) and that number simply doubles.
So OP: really curious to how you do the cooking, if any?
That being said, we still used 9600kWh last year which is more than double your consumption.
And the gas part is what's likely more of a problem in Europe - since a lot of that is coming from Russia (it's also non-renewable).
I have a fairly small house, with only 2 adults, that's full electric (appliances, cooking, hot water, heating). We have a dishwasher (used every other day) and we also use a washing machine (and sadly often the heat pump dryer because there is no space for a drying rack).
We use, all in, about 4000 kWh/year. About 750 to 1000 of that is for heating the house and hot water. My idle usage is higher then your average, which is somewhat crazy. I have about 30-40W for the ventilation system, about 20W for modem/router/wap, 10W for home server and the rest is for fridge/freezer I guess.
Even just cooking on the induction hob, or using the (electric oven) will already blow your entire day budget. Let alone a dishwasher or washing machine cycle.
I'm fully aware that the biggest improvement can be made in being aware of your usage (which I am, I monitor it carefully) and try to be more mindful about it. Yet it's not easy to lower the numbers significant.
Some years ago, as a single, I also was (well) below 1000 kWh/year. But that was without a dishwasher, or dryer. And generally cooking less often/fancy then my wife currently does. Work from home with 2 adults (with big monitors, a beefy desktop, etc) also adds energy usage.
