Carbon Footprint 101: Household appliances that consume the most energy and cost you the most

Recent climate reports have painted a precarious picture of the decades to come due to the effects of climate change.

everyone is now wondering what they can do to help slow the warming of our planet and hopefully reverse the effects of human-induced warming in the years to come.

A large portion of our individual carbon footprints are generated in the home, so Independent.ie has compiled a list of the household appliances that use the most energy.

The basic unit of electricity is the kilowatt hour (kWh). Simply put, 1 kWh is the amount of energy used by a 1 kW (1000 watts) electric heater for 1 hour.

Using Ireland’s standard unit rate, using 1 kWh will cost you around 22 cents, depending on your supplier.

Your electricity is measured in kWh and the average Irish household uses 4,200 kWh per year.

A general rule of thumb is that if your appliance heats up something, it will be in the upper echelons of cost.

Instant electric shower / electric water heater

An instant electric shower or immersion heater will use 1 kWh every 7-10 minutes.

Hob, kettle and tumble dryer

Using a large cooking ring, boiling the kettle or using a dryer will take 20 to 40 minutes to use 1 kWh.

Washing machines and dishwashers

Washing machines and dishwashers consume slightly less energy and take about 70 to 100 minutes to use a kilowatt hour.

Computers and televisions

Computers and televisions are a lot cheaper to run, which is just as good considering the number of hours we spend watching them. It will take about four to six hours for a television or computer to consume 1 kWh.

Refrigerators and freezers

Refrigerators (around 5 kWh per day) and freezers (around 3 kWh per day) are also relatively inexpensive compared to other appliances.

Ampule

A single standard 100 W bulb will take between 10 and 50 hours to burn 1 kWh.

Consoles

The good news for gamers is that the PlayStation and Xbox consoles would take around six to 12 hours to use a kWh, which means they are much cheaper to run than a kettle or hairdryer (50 minutes per kWh). kWh approximately).

It is important to note that these are indicative usage rates and the actual usage rate will depend on the age and energy efficiency of the device.

If you want to calculate exactly how many kWh a device can use per day, you can take the wattage of any device and multiply it by the number of hours of operation.

So if its power is 100 watts and it has been running for two hours, then it has used 200 watts. Then just divide that number by 1000 to see how many kWh the device used.

Energy monitoring technology also means you can now see exactly what you are using. Most importantly, you can see which devices are costing you the most, moderate your consumption accordingly, and anticipate your future electricity costs.

As you learn about the cost of appliances, this type of smart monitoring system also allows you to use timers to program your appliances or heating systems to only turn on when they are. are necessary.

This means that you will avoid unnecessary waste, which will improve your energy efficiency and save you money.
