I have a <1300 square foot home, in the northeastern US, with adjoining units sharing the walls on either side, so not exposed to the outdoor temperatures except at front and back, and it has gas heat, not electric, and I think I have all LED lighting at this point. I do not have a electric car either. The biggest piece of glass on an external wall is in a practically new patio door that's supposed to be to the highest thermal standards. I apparently use a little over 7000 kWh per year. So while 5000 kWh per month does sound high, 3500 kWh per year sounds almost as inexplicable on the low side. Maybe people in the Netherlands and Germany don't have A/C, as people in the US from NY to Texas do, but I'm not sure that's a plausible explanation. My power consumption isn't that much lower when the A/C is off; while the year-round average is about 600 kWh per month, it's typically over 500 kWh in the colder part of the year. Another data point is that our power company (which is a UK company by the way) sends a periodic comparison of energy usage with similar homes, and mine is supposedly a little higher than peers but not that much. I felt like something must be wrong, in fact, when I first moved in, and tried to figure out what was drawing all the power when the A/C is off. I didn't come to any conclusion except that maybe the furnace has a blower fan that draws a lot of power. I have the opposite of a plan that passes through the spot price, by the way - my payment plan attempts to equalize the seasonal variations and charge the same amount each month for the whole year.
