A ceiling fan can be used to both cool and heat our houses.
But they use electricity, so it is good to know how much electricity a ceiling fan uses and how much it costs to run a ceiling fan.
TABLE OF CONTENTS – QUICK NAVIGATION
To get to know how much electricity a ceiling fan uses, first you need to know how much power it consumes.
The power consumption of a ceiling fan can be found on its energy label.
Alternatively, the power consumption can also be found by searching for the fan specifications on the internet.
For example, if your ceiling fan is rated as 50 Watts (W), it will consume 0,05 Kilowatts per hour (kWh).
50 W / 1000 = 0,05 kWh
Just note that the power consumption is only a rough estimation because it will vary depending on the settings.
For example, a lower fan speed will probably use less power than a medium or higher fan speed.
If you only know the voltage and current of your ceiling fan, you can calculate the power consumption in Watts using the calculator below.
For more information about Power, Voltage, and Current, scroll down to the ‘Electricity Measurement Units’ section.
Once you know the power consumption, the calculator below can estimate the electricity cost of a ceiling fan over time.
You need to adjust the values in the PARAMETERS section to your requirements, and the calculator will automatically display the RESULTS section.
> If your ceiling fan has a power rating of 50 Watts
> If you use it for 10 hours a day and 220 days per year
> If you are paying 0,2 euros (or dollars or pounds) per every kWh you consume
You will be paying 15,4 euros (or dollars, or pounds, or…) per year in electricity costs.
If you don’t know how much you are paying per kWh, you should be able to find the cost per kWh on your electricity contract or in one of the electricity bills.
Alternatively, if you don’t have access to your contract or electricity bills, this website shows the electricity cost per country.
Here are a few other examples from our ‘Electricity usage and electricity cost calculators‘ page that may be of your interest:
If used correctly and efficiently, a ceiling fan can save electricity on heating and cooling.
Here there are some tips and facts that can be of your interest:
1.- Use the ceiling fan to create a cooling breeze during summer
Most ceiling fans have an option allowing users to choose the rotation type, clockwise or counterclockwise.
During summer, ensure that the ceiling fan’s rotation is pushing the air down from the ceiling to the floor. That will create a pleasant and refreshing draft.
An air conditioner uses much more electricity than a ceiling fan so supplementing an air conditioner with a ceiling fan will decrease your electricity usage by efficiently distributing the cool air produced by the air conditioner unit.
2.- Use the ceiling fan to distribute the heat during winter efficiently
During winter, ensure your ceiling fan is set up to pull the air from the floor to the ceiling.
This airflow will pull the hot air from the floor to the ceiling, across the ceiling, and back down by the sides to the room’s floor.
An efficient heat distribution will reduce the amount of electricity used for heating and therefore reduce your electricity cost.
3.- Use your ceiling fan only when needed
A ceiling fan can be a good supplement to save on heating and cooling when used efficiently. Just make sure you power off your ceiling fan when it is unnecessary.
A ceiling fan does use around 50 Watts.
In the context of ceiling fans, energy and power are the same.
A ceiling fan does use around 50 Watts.
As you can see on the ‘Ceiling fan electricity usage and cost calculator,’ it takes just a few watts to run a ceiling fan, and they are pretty economical.
And the air conditioning unit is a different story…
For more information, look at the page where we explain the electricity usage and cost of an air conditioning unit.
On that page we have made available a calculator that can be used to calculate the electricity cost of an air conditioning unit over an hour, day, and year.
In 99% of the cases, an air conditioner uses more electricity than a ceiling fan.
There is only one situation when a ceiling fan will use more electricity than an air conditioner.
If the air conditioner is barely used, but the electric fan is in use 24×7, over time, the electric fan will use more electricity than an air conditioner.
If you want more details, compare the ‘Electricity cost calculator’ results between a ceiling fan and an air conditioner.
In the ‘Electricity cost calculator’ section, we have made available a calculator that can be used to calculate a fan’s electricity usage and electricity cost.
‘How much electricity does a ceiling fan use per month’ will depend on two factors: The power consumption of the ceiling fan and how many hours per day is the ceiling fan in use.
Not everybody is familiar with terms like Watts, Kilowatts, or Kilowatt hours, so if you would learn more about them, look at this YouTube video we have prepared about this topic.
Or you can have a look at these electricity measurement units calculators to get a better understanding of:
> What is a Watt (W), and how to transform Watts into Kilowatts
> What is a Kilowatt (kW), and how to transform Kilowatts into Kilowatts hour
> What is a Kilowatt hour (kWh), and how to transform Kilowatts hours into other units
> What are Power (P), Voltage (V), and Current (I)
Energy conservation can be defined as the decision and the act of using less energy.
Energy conservation both benefit you and the environment
The act of saving and conserving electricity benefits you because you will pay less for your energy bills.
And it also benefits the environment because conserving electricity prevents unnecessary waste of natural resources.
Now, at the individual level, it may not look worth trying to save a few watts here or there.
Still, every little one count, and if hundreds or thousands of us save a little every time, it will contribute to conserving our natural resources.
If we could reduce the electricity usage of our electric fans, even a very small amount, it would significantly impact preserving our natural resources.
For example, if 9000 households save as little as 10 Watts per day (0,01 kWh) on electric fans’ electricity usage, that would add to 32850 Kilowatt hours (kWh) saved per year.
9000 households x 0,01 kWh per day x 365 days per year
32,850 kWh saved per year
That is a considerable amount of electricity, but let’s add additional perspectives for clarity:
> Assuming an average cost of 0,18 euros (or dollars, or pounds, or any other currency) per kWh, we would collectively be saving nearly 6000 euros per year.
> To produce 32,850 kWh of electricity, it is necessary to use around 17 metric tons of coal or 56 barrels of residual fuel oil.
In any case, it is clear that small energy savings do count when looking into the bigger picture.
