How Much Electricity Does A Fan Use: Learn The Formula

How Much Electricity Does A Fan Use: Learn The Formula

When we're on a tight budget, we prefer knowing our electric usage. And although energy consumption has several factors, it's helpful to know how much electricity does a fan use. Let's find out!

The Formula: How Much Energy Does A Fan Use

There are factors to consider when finding out how much electricity does a fan use.

The formula for energy consumption is based on the watts your fan uses daily. Below is a sample for your reference:

  • A 48-inch ceiling fan uses 75 watts
  • Your fan stays on for 4 hours
  • Your electric bill notes the kWh at $0.10

So, how much electricity does a fan use?

  • 75 watts x 5 = 300 watts of electricity a day.
  • Divide the daily wattage by 1000:
  • 300 watts / 1000 = .3 
  • It costs 3 cents a day to use your fan for 5 hours:
    .3 x $0.10 = 0.03 
  • Multiply the daily cost of your fan's use by 30 to get an estimate of your monthly use:
    .03 x 30 = $ .9

This means that with a 75-watt fan that runs 5 hours a day, it only costs close to a dollar of usage for the whole month.

That sounds like good news and for a good reason. Fans are a cheaper alternative to air conditioning, and this is an obvious fact, but if you can't help using the AC, you can supplement air conditioning use with fan use so you can save on electricity.

Note: An air conditioner uses between 350 to 7500 watts of electricity, which is a big difference.

Energy Efficient Fans To Consider

  • Ceiling fans provide lighting and heat relief. They are easily installed and are at 50-90 watts.
  • Window fans use 35 to 100 watts and are cheaper than ceiling fans. It can be supplemented with an AC so you can save on energy.
  • Tower fans use 48 to 100 watts to operate and can be easily moved from room to room.

Tips For Saving Electricity

  • Saving electricity may seem overrated, but we need reminders now and then.
  • Switch off the lights and any appliances when not in use like bathroom lights and porch lights.
  • Consider purchasing energy-saving lighting.
  • Keep your curtains closed and shut the doors so you can keep coolness in during warm months.
  • Avoid using dryers for your clothes. If you have time and space, allow your clothes to dry naturally to save on electricity.
  • The refridgerator is one of the most expensive appliances in your home because it stays on 24/7. Make sure fridge doors are sealed shut and use the 2nd freezer only when it's needed.
  • Consider investing in solar energy systems. Although it may be costly upfront, everything will pay off eventually.
  • Insulate your ceiling so that you can manage cooling and heating better.

Conclusion

Knowing how much electricity does a fan use includes understanding how to save on electricity. Fans as effective tools for heat relief are more energy-efficient than air conditioning systems. But with this knowledge, you can finally manage all your appliances well.
