Q. Does window fan consume high electricity?

Answer

Yes window fan consume high electricity. A window fan like most other types of fans uses significantly less energy than an air conditioner. Window fans typically use between 35 and 100 watts of electricity though this varies widely by make and model. Around 55 watts is the average power consumption of a window fan with 36-inch blades. In general a window fan with 48-inch blades uses 75 watts of power while a fan with 52-inch blades requires 90 watts. According to the National Renewable Energy Laboratory the average whole-house fan consumes between 120 and 600 watts of electricity; this is still significantly less power than that required by a central air conditioner although the exact quantity varies depending on the size of the fan's motor.
