That is a great question, I hadn't really looked. I was about 2000 SEK a month in the winter, and 1300 SEK a month in the summer, but this spring we switched electric companies, and now this summer we are paying more like 600 SEK a month. It will be interesting to see how that changes in the winter. Note that, in theory, we aren't spending so much electricity on the heating as we have "bergvärme" (or "down hole heat exchange" in English), but it does require some power to operate.

This is for a small house with a full basement, and a computer server in said basement.

Note that once converted to US $ my numbers are considerably higher than most of the people commenting have been mentioning.
