Power consumption 7000 kWh live with 3 people in one apartment my devices I use etc. See description?

I have 3 people with my family a power consumption of 7000 kWh

I very often use a good gamer laptop and well my brother now and then a PC my fan is continuously on stage measures to 1-2 and yes these are the electronic things but how can it be that we consume so much so I have to say that I do my room light is on for 12 hours a day, but otherwise in other rooms I also switch off the light when I see someone has forgotten so what do you say?

The usual suspects among the power guzzlers are:

all applications where electrical energy is used to generate heat
all applications that are operated over a long period

It may be that my neighbor is drawing electricity from me, can my electricity provider see if my neighbor is cheating on me?

Yes, sounds a lot but for 3 people still in the frame. If the warm water runs on electricity anyway.

3 people and they are at home all day:

Light on for 12 hours a day

That's normal. Especially with gaming equipment.

There will also be a washing machine and dryer and hold the instantaneous water heater.

That is not the job of the supplier.

The Hasue owner must arrange for the house system to be checked at a registered electrical company.

It would also have to be checked whether the annual accounts (including those of previous years) insist on actual readings or whether in between (incorrect) estimates were made.

I have to take a look at everything I do not know because I have to ask my electricity provider for anything else.

? You should actually know that by heart.

I note the meter reading every month so large deviations from the average consumption are noticed relatively quickly after 4 weeks. With us the old refrigerator was practically in "continuous operation".

The time required is small
