To know the electricity usage of an air conditioner, first you need to know how much power does it consume.
The power consumption of an air condition unit depends on the model but, in average, they use around 1500 Watts.
On this page you will find out:
> How much electricity does an air conditioner use
> Air conditioner electricity cost calculator
> Electricity measurement units: Watt, Kilowatt or Kilowatt hour
> How to lower the electricity bill
> What is energy conservation and how does it benefit you and the environment
Alternatively, you may want to fast forward to the air conditioner electricity cost calculator.
If you would like to know the power consumption of your air conditioner, most probably you can find the electricity usage on the unit’s specifications label.
Alternatively, you most probably can search for the specifications through an internet browser, as we show on the picture below.
Once you know the power consumption of an air conditioner, you can easily calculate the electricity usage and the electricity cost.
For example, this air conditioner consumes 1300 Watts (W) or 1,3 Kilowatts hour (kWh).
1300 W / 1000 = 1,3 kWh
As we are paying to our electricity provider 0,217 euro per every Kilowatt hour we consume, this means that this AC unit would cost us around 0,282 euro per hour.
1,3 kWh x 0,217 euro per kWh = 0,282 euro per hour
Once you know the power consumption, the calculator below can be used to estimate the power consumption and the electricity cost of an air conditioner over a period of time.
You just need to adjust the values in the PARAMETERS section to your requirements and the calculator will automatically display the RESULTS section.
For example, if your air conditioner:
> It has a power rating of 1300 Watts
> You use it for 10 hours a day for 150 days per year
> You are paying 0,217 euro (or dollars or pounds, or…) per every kWh you consume
You will be paying around 2,8 euro (or dollars, or pounds, or…) per day and around 423 euro per year in electricity costs.
Still, 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 electricity consumption.
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.
A few other examples from our ‘Electricity usage calculators‘ page that may be of your interest:
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)
These are some simple and effective way to reduce the electricity usage and the electricity cost of an air conditioner:
1.- Use the thermostat and timer
Every single degree counts and by adjusting your conditioner by just one degree you could save up to 10% on electricity.
Use the thermostat to setup the temperature to a comfortable but reasonable threshold. And se the timer to power off and on the air conditioner so it is only working when when needed.
2.- Use curtains and blinds
The curtains and blinds will help with keeping your home cooler. If you are living in a warm area and using a lot of electricity and money to keep your home cool, it may be worth to install some thick curtains to keep the sun rays away.
3.- Power down those heat emitting appliances and devices
It may not always the possible or feasible but turn off those appliances and devices that emit heat. The thermostat will have to work harder to compensate for the temperature increase and will consume more electricity.
4.- Improve your home’s insulation
Also, if your home is not well insulated the heat will permeate and force the air conditioner to consume more and more electricity to keep the temperature set in the thermostat.
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.
For example, if 9000 households would manage to save as little as 10 Watts per day (0,01 kWh) 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.
