Two-thirds of greenhouse gas emissions are linked to energy consumption. Apart from that, the current situation resulting from the war in Ukraine imposes a stance of maximum austerity. Both the planet’s climate emergency and the energy responsibility recommended by institutions make it necessary to dose its use more than ever before. In many cases, however, consumers are not entirely aware of what is what. household appliances or appliances are the most energy consuming. Obviously they all are, but some are the ones that absorb the most electricity.
According to the Energy Diversification and Conservation Institute, average Spanish house gaabout 4,000 kWh per year electricity.
The devices that consume the most energy at home are:
1.- Refrigerator
dir-dir most energy consuming devicewell represents in total 19% of average electricity consumption in a house.
In reality, its power is low, about 200 watts (ten times less than that of a hair dryer). Again, Since it is in use for 24 hours, its final consumption is very high. In fact, it shouldn’t stop working at any time.
The refrigerator works better and spends less. rear air circulation and hold it away from heat sources or sunlight directly. In addition, it is convenient to make sure that it has adjustable power and, even better, low consumption.
In addition, it is necessary to create a suitable temperature, Do not put hot food and only open when necessary.In addition to keeping the ventilation circuits clean, it is recommended to dust the back of the refrigerator at least once a year.
2.- Washing machine
The washing machine has a huge consumption of between 1,200 and 1,500 kWh, making it one of the most energy consuming household appliances.
Total, the average consumption of the washing machine represents about 12% of all household appliances. A percentage that can always be lower when used correctly: wash cold, wait until full or choose a program that suits your specific needs.
80% to 85% of the energy consumption it produces comes from heating the water during washing, so if you use low temperature programs, you will reduce the expenditure.
3.- Television
Television and washing machine usually appear very close to each other in the ranking of household appliances and electricity consumption. According to IDEA TV, 7.5% of the total domestic consumption, while the washing machine stays at 7.3%, other sources mention 12%.
Absolutely, television It is one of the less energy-consuming household appliances: only 100 kWh. However, its long-term use (about 21 hours per week) means that it involves an expense comparable to a ceramic hob at that time.
The size of television screens has doubled in the last decade. And in general, the bigger the screen, more energy needs. After LCD (liquid crystal), the least consuming display is LED.
television in standby mode, it can consume up to 15% of the consumption under the following conditions:operation rms. Therefore, it should be turned off completely when not being watched.
It is best to use a power strip with a power strip that completely shuts off current to the equipment when turned off.
4.- Tumble dryer
This device is a The big energy consumer is actually the absolute biggest consumer.. However, since it offers great comfort, its use in homes is becoming more and more common.
recommendation only use in emergencies, something that can almost always be done on a traditional clothesline if you live in particularly rainy parts of Spain when the weather conditions do not allow the clothes to be dried in the sun.
Recommended for energy saving spin the laundry before putting it in the dryer. In addition, cotton laundry and heavy clothing should not be dried in the same loads as light clothing.
5.- Oven
electric oven one of the largest consumers in the home as it accounts for around 9% of the total electricity cost. However, its consumption is not one of the largest, as it is used less often than other household appliances.
A good trick to reduce consumption is to switch it off before the cooking is finished: The remaining heat will be enough to finish cooking. Compulsory not turning on the oven needlessly to review food. Each time it is done, at least 20% of the accumulated energy is lost.
6.- Glass ceramic
There are differences in electric stoves: linduction hobs consume 20% or 30% less electricity Second to traditional ceramic hobs, it is the second most consuming household appliance in absolute terms, especially twice that of a refrigerator or washing machine.
Make sure that the bottom of the pans is slightly larger than the cooking zone so that the heat of the kitchen is used to the maximum.
Closing the lid of the container you are cooking will help you save up to 25% of energy. With the ‘Vitro’ you can also switch off five minutes before and finish cooking with the remaining heat of the hob.
7.- Dishwasher
a lot of time The use of this device is more economical in terms of both water and energy than traditional hand washing.As long as it is used when full, almost 10 to 14 liters of water are used per cycle.
90% of the energy consumption takes place during the heating of the water. However, technological developments make it possible to have models that select the water temperature and economical programs that allow the heat from washing to be reused for rinsing or drying without consuming energy again.
8.- Computer
Computers consume more electricity than it seems at first glance, and 4.6% of the energy cost of a house.
Laptops consume much less than desktop computers. The screen is the element that consumes the most electricity.More efficient than LCD.
You should be careful to leave it in standby, even if it doesn’t seem so, what is called ‘phantom consumption’, a low electricity consumption is maintained in standby mode, less than one watt. The screensaver that uses the least energy is the black screensaver.
9. – Microwave
Using a microwave instead of a conventional oven It means 60% energy saving. Also, because they are very fast in their functions, they work for a very short time.
10.- Small household appliances
In this section, many different types of devices are suitable, whose energy consumption reflects very large differences.
Those that produce heat are the ones that consume the most, Because they have very high powers, such as a 1,500-watt iron or 1,200 types of hair dryers. The food processor beats them with 1,950 watts of electrical power.
