Both a dehumidifier (avg 500 w) and a well pump (avg 700 w) can burn through a lot of power DEPENDING on how much they are run. My basement dehumidifier runs to keep humidity at around 50% so how much depends on how humid. Lots during summer (100+ kWh per month, $16+). The unit is off during winter because humidity is low and the temp is 60 degrees or less.
The well pump, how much water is used? With 2 people I would think not a lot. How deep is the well? Deep wells require more energy to move the water to the surface.
How do you cook? We tend to use our microwave a lot and don't heat the oven or cooktop that often. The microwave is fairly efficient in placing heat in the food but not the surrounding space.
Lots of factors which are "normal" usage but can create quite a variance in to use.
