A regular fan uses 10 to maybe 100W depending how fast it's going, so it converts that electricity to kinetic energy in moving air. As the air slows by hitting other air or walls etc that kinetic energy has to go somewhere, it becomes waste heat.

So the same as a 10-100W light bulb which probably is enough to be noticeable in a room over a whole day
