An electric fan it is handy device to have on those hot and humid days.
So, it is good to know how much electricity does an electric fan use and how much money it is going to cost us to keep the fan running.
TABLE OF CONTENTS – QUICK NAVIGATION
To find out the electricity usage, first you need to know how many watts does your electric fan consume.
This information can be can be found on the fan’s specifications label or by searching from it on the manufacturer’s website.
Just note that if your electric fan has as an option to adjust the air flow intensity level, the electricity usage will vary between levels.
This is, if your electric fan it is rated with a power of 45 Watts, only the strongest air flow level will consume 45 Watts while the lowest or intermediate air flow levels will consume less electricity.
The only way to accurately know an electric fan power consumption over time it is to use a plug in power meter to measure the electricity usage.
Still, if you want to make an estimation, according to it’s specifications this fan consumes 50 Watts (W).
50 W / 1000 = 0,05 kWh
If you only know the voltage and current of your electric 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.
The calculator below can be used to estimate the power consumption and the electricity cost of an electric fan over time.
You just need to adjust the values in the PARAMETERS section to your requirements and the calculator will automatically display the RESULTS section.
> If your fan has a power rating of 45 Watts (W)
> If you use it 8 hours per day and 120 days per year.
> If you are paying 0,217 euro (or dollars, or pounds, or …) per every kWh you consume
The fan would add around 10 euro (or dollars, or pounds, or …) to your yearly electricity bill.
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 don’t have access to your contract or your electricity bills, this website does show the electricity cost per country.
A few other examples from our ‘Electricity usage and electricity cost calculators‘ page that may be of your interest:
If you want to know the exact electricity usage of an air conditioner, your best option is to use a plug in power meter to measure the exact power consumption and electricity cost.
Clicking on the image below it will redirect you to the Amazon page where you can have a look to the specifications of the power meter we use for our measurements.
All of our house appliances and devices like the washing machine, the dishwasher, the TV or the printer are plugged to a wall socket.
So, with a power consumption meter we can determine how much electricity our appliances or devices are using and, more importantly, we can measure the electricity usage over a period of time.
If you want to find out how you can use a plug in power meter to measure your electricity usage and electricity cost, have a look to this YouTube video.
The electricity usage of a device depends on it’s power consumption.
A small electric fan does not use much power, most of them just use between 30 to 45 watts.
A low power consumption means that a fan does not use a lot of electricity.
But be careful, more advance fans or fans with cooling and heating options may use quite a bit of electricity.
Find out how many watts does a fan use and you will be able to calculate the electricity usage and electricity cost using the calculator from the ‘Electricity cost calculator’ section.
Most of the small fans use between 30 to 50 Watts.
Some more advance fans, like the tower fans, will use around 100 Watts.
Those fans that have additional features, like cooling or heating, will use many more watts. Depending on the characteristics, they can use up to 2000 Watts or even more.
Energy, power and electricity are terms that relate to the same question, which is ‘how much electricity does an electric fan use’ and ‘how much does it cost to run an electric fan’.
Depending on the size and characteristics of the fan, it will use more or less energy/power.
If you want to know how much energy/power does a fan use, you just need to find the power rating of the electric fan.
Once you know the power rating, you will be able to calculate the electricity usage and electricity cost using the calculator from the ‘Electricity cost calculator’ section.
An small electric fan with a power consumption between 30 to 50 Watts, it is NOT expensive to run.
A larger fan, like a tower fan, with a power consumption of 100 Watts, it is NOT expensive to run unless it is kept on 24×7
A fan with additional heating or cooling features, YES it can be expensive to run.
Not everybody it is familiar with terms like Watts, Kilowatts or Kilowatt hours so if you would like to learn more about them, have a look to this YouTube video that we have prepared about this topic.
Or you can have a look to this 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 to 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 does benefit you because you will be paying less on your energy bills.
And it also does benefit the environment because conserving electricity prevents any unnecessary waste of natural resources.
Now, at individual level it may not look worth to try to save a few watts here or there.
Still, every little counts and if hundreds or thousands of us do save a little every time, it will make an important contribution towards conserving our natural resources.
If we could reduce the electricity usage of our electric fans, even a very small amount, it would make a big impact on preserving our natural resources.
For example, if 9000 households would manage to save as little as 10 Watts per day (0,01 kWh) in electric fans electricity usage, that would add to 32850 Kilowatt hour (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 euro (or dollars, or pounds, or any other currency) per kWh, we would collectively be saving nearly 6000 euro 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 really count when looking into the bigger picture.
