* Size: Larger fans consume more power than smaller ones.
* Speed setting: Higher speeds draw more power.
* Type: Different fan types (e.g., box fan, tower fan, pedestal fan) have varying power requirements.
* Efficiency: Older or less efficient models use more energy than newer, energy-efficient ones.
A typical household electric fan will consume anywhere from 15 to 100 watts. However, most are in the 40-60 watt range.
To calculate the energy used over a period of time, you can use the following formula:
Energy (in kilowatt-hours) = Power (in kilowatts) x Time (in hours)
For example, a 60-watt fan running for 8 hours would use:
(60 watts / 1000 watts/kilowatt) * 8 hours = 0.48 kilowatt-hours (kWh)
Keep in mind that this is a rough estimate. The best way to know the exact energy consumption of your specific fan is to check its nameplate, which usually displays the wattage.
