How Much Electric Does a Fan Use?

Fans are a great way to keep cool in the summer, but they use electricity. How much electricity does a fan use? That depends on several factors, including how big the fan is and how often it’s running. Here’s what you need to know about electric fans and their energy usage.

How Much Electricity Does a Fan Use?

The answer to this question depends on the style of your fan. Most fans are either table fans or ceiling fans, and each type has different wattages.

Table fans are generally less than 50 watts and can be found anywhere from 15 to 40 watts in size. Ceiling fans can range anywhere from 100-500 watts depending on the size of the room they’re used in and how powerful you want them to be.

To figure out how much electricity your particular table or ceiling fan uses, you’ll need to look at its label or manual, click to show more. You could also try looking up its model number online; many manufacturers list detailed information about their products online including wattage usage by model number.

How Much Electricity Does a Ceiling Fan Use?

It is important to note that ceiling fans use around 100 watts of electricity. This number is significantly lower than an air conditioning unit, which consumes several hundred watts or even thousands of watts.

Ceiling fans can work at such low power consumption because they circulate the air rather than cooling it directly. The movement of the blades allows for better heat dissipation and keeps the room feeling cooler overall, though not as cold as an air conditioner would produce.

How Much It Costs To Run a Ceiling Fan

When it comes to the amount of electricity a fan uses, there are a few factors you need to consider:

  • The size of your ceiling fan and how many watts it uses
  • The speed at which it runs (if you have a choice)
  • Whether or not there is an option for low-speed operation in the summertime (or low-speed operation during high-heat alert days)

Do Electric Fans Use Power When Turned Off but Plugged In?

Fans use power even when they’re turned off but plugged in. In this case, the fan will continue to run at a low speed so that it can keep running smoothly when turned on again. 

However, it’s better to turn off your fans when you’re not using them so that you don’t waste energy on something as insignificant as keeping them from getting hot before starting up again later!

Does Turning the Thermostat up and Using a Fan Save Money?

The answer to this question is an astounding yes. Turning up your thermostat and using a fan will help you save money in two ways.

First, when you turn up your thermostat, it uses more electricity to cool down your home. Using a fan at the same time will help lessen this cost by creating air circulation that moves through your home without using as much power.

Second, fans can be used as an effective alternative to air conditioning during hot summer months when electricity costs are typically high. 

You may be able to find ways of keeping cool that require less energy than running an entire central cooling system for hours on end or purchasing new appliances such as ductless mini-splits or evaporative coolers—which are often expensive investments themselves!

Factors That Determine the Energy Used by a Fan

Many factors determine the energy used by a fan. 

  • Size and Speed

Larger fans have larger blades, which in turn require more energy to rotate them and move air around. The second factor is speed—the faster you want your fan to go, the more electricity it’ll consume.

  • The Temperature

The temperature plays an important role as well: if it’s hot outside or in your room then you may want to turn up the speed on your ceiling fan or desk fan so that it circulates cooler air, but remember that this will also use more power.

  • Size of the Rooms

The room size can influence how much electricity a fan uses because larger rooms need more airflow than smaller ones, meaning bigger fans will be required for greater circulation purposes.


Many factors determine the energy used by a fan. We recommend that you do some research about different types of fans before making a purchase so you know exactly what type of fan will work best for your needs. You should also consider whether or not it’s worth turning down your thermostat to save money on cooling costs when using electric fans during hot weather months.
