I have found that my house uses about 3kW a day when I am away from home. This seems quite a lot but is actually about 125W per hour. Looking at what is running when we are away there is quite a lot of stuff connected;

Fridge/freezers in kitchen and garage
Controllers on heating and water softener
Phone, hub and NAS box
DVD recorder on standby
Two fire alarms
A couple of clocks
Solar PV inverter and Immersun probably use a bit at night

I see from the grid web site that hydro-electricity generation has increased considerable in the last week or so. As most hydro is generated in Scotland has it been raining there lately? GONE - '07 TD4 GS manual Zermatt Silver

Going back to the post from Iliacus about what consumes electricity in your absence, reminds me of a little device I was once given that tells you about the current a device draws when plugged into it (and the device into a socket). I went about testing things in standby or switched on. It also worked out the energy consumed over time, so it calculated how much a 40oC wash cost in the washing machine... pennies in reality which was good, but whether 'on' or 'off' it consumes 10W which is quite a lot when it is doing nothing We have no easy means of isolating it which is a shame, unless I go to the trouble of fitting an isolation switch above the worktop it is installed under.

We have 2 fish tanks, a pond with UV and filter running amongst many other things, so it wouldn't surprise me that we clock up a couple of kWh per day even when we are not at home. 2016 BMW X3 30d SE in red
