Anecdotal observation: I just checked my monthly consumption since the beginning of this year and it averaged to 154kWh per month. I'm in Finland, I live in a flat and we have an electrically heated sauna that we use on a regular basis which isn't exactly very energy-efficient and, to think, we don't generally try to minimize the consumption of electricity at all, really.
Just wondering, what sort of consumption does that 200kWh include?
I am as baffled as you are, which is why we started keeping track of monthly readings. One of my acquaintances has a store selling electrical goods, and he too was very skeptical. We have a refrigerator, an electric cooker, water heater, TV, a PC, and other usual stuff. I used to leave the water heater on in the winter months. A faulty thermostat in the water heater is my best guess. I'll try this hypothesis out this winter, and probably buy a new one in summer. Anyway the possible culprits are few, so hunting it down should be easy.
(But the A/C unit's consumption is believable - it is rated at 1.8 units per hour, so around 5 hours usage for 30 days should push the usage up by 300 units.)
