A ceiling fan is hours × a modest wattage. Low is often around 30 watts, high around 60. That is why “leave it on, it’s fine” is mostly true compared with AC — and why leaving every fan in the house on high in empty rooms is still a pile of hours.
Fans cool people, not rooms. If nobody is in the room, the fan is moving air for no comfort. In winter, a reverse/low setting is a small wattage; it is not a heater.
This card is a room ceiling fan, not a bath vent and not a shop barrel fan. Those are different motors in Whatt.
Default is often about 50 watts and 8 hours. Change speed and hours to match the room.
At 18.8¢ per kWh, 50 watts for 8 hours is 0.4 kWh — about 0.08. All day (24 hours) on high at 60 watts is about 0.27. Cheap next to cooling. Not zero if you have six of them.
Empty rooms
Fans cool people. An empty room with a fan on high is hours × watts for no comfort. Bath fans and shop barrels are other motors.
