The 5 most wasteful household appliances at home and how to reduce consumption


Consumption Saving 3


Our home has become a nest of appliances that, although by themselves do not seem to generate too much expense, as a whole they represent a significant amount, so we will see how to reduce it with some very easy tricks.

A few articles ago we looked at what energy efficiency means and how it is important to help us save money in the medium term and avoid wasting energy uselessly, betting on those appliances that better performance out of the energy they consumed.

We will not talk about the need to have efficient appliances, since it would be a great way to save in all cases.

Today we will focus on knowing which are the appliances that consume more energy in our house and we will see some tricks to reduce this expense, as far as possible and help you and the planet.

How much do household appliances consume at home?

Red Eléctrica offers data that indicate that the economic expenditure generated by household appliances in an average Spanish home accounts for 66% of the total at home throughout the year. Thus, the correct operation and an intelligent choice of these can mean real savings for households in Spain.

On the other hand, IDAE indicates that the average energy consumption per home in our country is 3,487 kWh, with household appliances accounting for 55% of the total energy expenditure, almost 1,913 kWh.

Thus, a good option to reduce costs in the non-stop light cost escalation that we are living since the beginning of the summer is to look at what are the appliances that spend more and how we can make the most of their performance without wasting energy.

The following data are extracted from IDAE.

What are the appliances that consume the most energy at home?

1. Refrigerator

The refrigerator is by far the most energy-consuming appliance in our home, as it is the only one that has to be in operation 24/7. IDAE points out that its consumption is equivalent to 30.6% of total household appliances and 14% of total household expenditure, about 25 euros/year (REE).

Within the term, we can also include the freezer, although some houses have it separately, it is usual that it is included within the same appliance, so consumption rises to more than 36% of the total. Altogether, 30 euros per year.

Tip to reduce costs: maintain a temperature between 3 and 7 degrees and do not allow frost to form, although there are already refrigerators with this feature. Also, avoid putting hot food and overload it, and leave a space between the wall and the refrigerator for proper cooling of the system.

2. Television

The TV is the second most consuming appliance, with 12.2% of the total energy consumption at home. This may be a percentage that surprises many, as there is a widespread view that the television has lost much weight in homes in recent years thanks to the diversification of screens (mobile, tablets, PC ...).

Nothing could be further from the truth; data provided by the Statista portal indicate that most Spaniards watch TV on a recurring basis (83%). This shows that it is still a very present device in the daily lives of people, especially those over 64 years old, and that is why it occupies such a high position in this ranking.

However, the data also show a clear downward trend since the end of the last century, declining from 90.7% of daily consumption to the current figures.

Tip to reduce spending: do not use the TV as if it were a radio and turn it on if you are really going to watch something.

3. Washing machine

Another of the appliances recurrently used in our homes, the washing machine, ranks third in this ranking of dubious merit with 11.8% of total energy expenditure. Selectra calculates that an average Spanish family of 4 people using 4 washing machines a week spends 51 euros a year on this appliance.

In this case, the biggest expense comes from the need to heat the water in certain washing programs.

Trick to reduce the expense: as it is obvious after the previous statement, the simplest thing is to select short programs with cold water, because many times we only wash the clothes because we have used them and not because they are stained, so it is already enough. Another way to reduce costs is to fill to the maximum capacity to take advantage of each wash or opt for eco programs.

4. Electric oven

The penultimate appliance on this list is found in the kitchen and, in this case, it is not one of the most commonly used in the home, the oven, although if it is here it is because when it is on it spends a lot of light to heat its interior. It accounts for 8.3% of total consumption.

It does not help the fact that it is indicated in many foods that it has to be preheated, because this action translates into unnecessary energy expenditure because it is an "empty" heat, since it does not really serve to heat anything.

Trick to reduce the expense: we can make a more habitual use of the microwave, since many recipes also contemplate that option, here you can check it out some. As we have said, we can save the preheating and turn it off ahead of time to take advantage of the residual heat. One last tip, avoid opening the door prematurely; you lose heat (i.e. energy).

5. Computer

In last place we have the PC with 7.4% of total household consumption. In this case, although it is true, there are some peculiarities that mark its consumption. For example, laptops consume less than tower computers, although consumption also varies depending on the brand and its age (newer ones are usually more efficient).

It is also necessary to take into account the recent teleworking, since it is obvious that we will spend more energy due to increased use. CHC Energy notes that the annual expenditure on the PC in this case (a day of 8 hours and 2 hours of leisure, 10 hours total) would be 110 €, provided that it is always kept on, about 0.30 euros per day.

Tip to reduce costs: specialized websites such as 3DJuegosPC recommend looking at the computer's configuration and adopting "reduced usage plans" that allow "limiting the use of parts of the equipment for specific tasks", such as turning off the screen when not in use or other elements such as the processor or some ports. In addition, we can use dimmed lighting or opt for LED technology, as well as opt for the energy saving mode, which deactivates some other non-essential functions. Finally, turning off the PC when it is not being used is another recommended action.

A recommendation for appliances such as the TV or PC is not to leave them on stand by, since IDAE points out that phantom consumption in this mode of household appliances accounts for 10.7% of total household consumption. In some cases it will not be possible, as in the case of the refrigerator; in others it is not necessary, as in the case of the oven, but whenever possible we should avoid this option to help reduce energy consumption and unnecessary economic expenditure.

Once we have seen that we can reduce consumption and expenditure with some simple tricks it is time to say... See you soon!
