how much electricity does a electric fan use?
18483
At the midpoint, 70 watts, if a kilowatt costs 10 cents per hour, the fan would cost 0.7 cents per hour (0.07 kwh x 10 cents). Extend that out to a month and it works out to $5.04 per month if it runs around the clock (0.7 cents per hour x 24 hours x 30 days).

A small home in a temperate climate might use something like 200 kwh per month, and a larger home in the south where air conditioners account for the largest portion of home energy usage might use 2,000 kWh or more. The average U.S. home uses about 900 kWh per month. So that's 30 kWh per day or 1.25 kWh per hour.

The cost of ceiling fans On the plus side, the main benefit of ceiling fans is their supremely low cost to run. They can cost as little as 2c per hour to run, which makes them an obvious choice from a cost perspective. This allows you to run them for longer, and at less cost than an air conditioner.

Annual running cost* Take the extreme example of a high speed (5) fan left on for 24 hours. At a rate of 28.7c/kWh, that will cost you 31c/day or as much as $113/year per fan.

A window air conditioner with a cooling output of 12,000 BTU uses approximately 15 amps from a 125 volt outlet. This translates to approximately 1.8 kWh. At the end of a month, one window air conditioner will cost about $35.60. Remember, that's only for one room.

a good window AC unit runs on 1.2 kilowatts and costs 14 cents an hour to run. a three-ton central air unit (a common cooling system), runs on about 3 kilowatts and costs about 36 cents an hour to run. a good ceiling fan? It draws only 30 watts to run, costing about 1 cent per three hours of use.

An average central ac will use 3000 to 5000 watts of power for around 9 hours a day during the hotter months. Click calculate to find the energy consumption of a central air conditioner using 3500 Watts for 3 hours a day @ $0.10 per kWh.

How much electricity does an air purifier use? According to Energy Star, the average air purifier consumes 550 kilowatt hours per year in electricity, or approximately as much energy as a modern refrigerator. If you're concerned with energy conservation, choose an air purifier with the Energy Star label.

So how much electricity are you using? We went shopping online and found typical box fans range from 40-100 watts. At the midpoint, 70 watts, if a kilowatt costs 10 cents per hour, the fan would cost 0.7 cents per hour (0.07 kwh x 10 cents).

Switch off that fan While a tubelight consumes around 55 watts per hour, an average fan consumes 75 watts. Old models and inexpensive fans can guzzle up to 90 watts. Replacing your old fan with a power-saver model makes sense as a BEE rated fan consumes around 50 watts.

Small wind turbines used in residential applications typically range in size from 400 watts to 20 kilowatts, depending on the amount of electricity you want to generate. A typical home uses approximately 10,932 kilowatt-hours of electricity per year (about 911 kilowatt-hours per month).
1378185
If your typical exhaust fan requires 1 watt per 3 to 5 cfm (nominally), you will draw 30 to 50 watts. Watts are a measure of power so, in general, your typical bathroom exhaust fan would probably require the equivalent amount of power as a 40 watt light bulb, give or take.

Running a fan takes a lot less electricity than running an air conditioner; ceiling fans average at about 15-90 watts of energy used, and tower fans use about 100 watts.

Central AC is simply an energy hog. A window unit AC uses 500 to 1440 watts, while a 2.5-ton central system uses about 3500 watts. That's a lot of power. A floor fan uses only 100 watts on the highest speed, and ceiling fans use only 15 to 90 watts depending on speed and size.

A window AC unit can use anywhere from 500 to 1440 watts of electricity to run, while a typical central air unit in the average sized home uses about 3500 watts.

An air conditioner uses roughly about 5-9 times as much electricity as a fan. While the amount may vary from model to model, this rule holds true for all of them. Even on the low setting, an air conditioner uses as a very large amount of electricity when cooling. Fans are much more cost-effective in terms of energy use.
