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 climatic emergency of the planet and the energy responsibility offered by the institutions are forcing us to dose this energy like never before. Yet consumers are often not entirely aware of what is what. household appliances or devices are the ones that consume the most energy. Of course they all do, but some are the ones that absorb the most electricity.
According to the Institute for Energy Diversification and Conservation, average Spanish house gasta about 4,000 kWh per year Electric.
Here are the devices that consume the most energy at home:
1.- Refrigerator
This 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 a hair dryer). Again, Since it is in use for 24 hours, its final consumption is very high. In fact, it should never stop working.
Refrigerator works better and spends less air circulation at the back and hold it away from heat or sunlight sources directly. In addition, it is convenient to make sure that it has adjustable power and, even better, low consumption.
In addition, a suitable temperature should be established, do not put hot food and only open when necessaryIn addition to keeping the ventilation circuits clean it is also recommended to remove dust from 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 appliances.
Total, the average consumption of the washing machine represents about 12% of all household appliances. A percentage that can always be lower if used correctly: cold wash, wait until it’s completely filled, or choose a program that fits specific needs.
80% to 85% of the energy consumption it produces comes from heating the water during washing, so you will reduce costs if you use low temperature programs.
3.- television
Television and washing machine appear to be closely linked in the ranking of household appliances and electricity consumption. According to IDEA While TV accounts for 7.5% of the total domestic consumption, while the washing machine stays at 7.3%, other sources mention 12%.
In absolute terms, television It is one of the less energy-consuming devices: only 100 kWh. However, its long-term use (about 21 hours per week) means that it requires 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, the more energy you need. The least consuming display is LED, followed by LCD (liquid crystal).
TV in standby mode, it can consume up to 15% of the consumption in unfavorable conditions.malfunctions. 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 power to the equipment when turned off.
4.- Tumble dryer
This device is a The big energy consumer is, in fact, the absolute biggest consumer.. However, it is gaining popularity in homes because it offers great comfort.
recommendation only use in emergencies, Or if you live in particularly rainy areas of Spain when the weather doesn’t allow for drying clothes in the sun, it can almost always be done on a traditional clothesline.
Recommended for energy saving spin the laundry before putting it in the dryer. Also, cottons and heavy clothing should not be dried in the same loads as light clothing.
5.- Oven
electric oven one of the largest household consumers as it accounts for around 9% of total electricity consumption. However, since it is used less than other devices, it is not one of the highest in consumption.
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 avoid opening the oven Unnecessarily reviewing food. Each time it is cast, at least 20% of the accumulated energy is lost.
6.- Vitroceramic
There are differences in electric stoves: linduction plates consume 20% or 30% less electricity more than traditional ceramic hobs. The latter is the second most consuming appliance in absolute terms, especially twice as much as a refrigerator or washing machine.
In order to use the heat of the kitchen at the maximum level, make sure that the bottom of the pots is slightly larger than the cooking area.
Putting a lid on the pot you are cooking will help you save up to 25% energy. With the ‘Vitro’ you can also switch off five minutes before and finish cooking with the remaining heat of the plate.
7.- Dishwasher
a lot of time this appliance is cheaper to use, both in terms of water and energy, than with conventional hand washingbecause only 10 to 14 liters of water are used per cycle as long as it is used when full.
90% of energy consumption occurs during water heating. However, technological developments make it possible to have models that select the temperature of the water 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 a house’s energy consumption.
Laptops consume much less than desktop computers. The screen is the element that consumes the most electricity.Being more efficient than LCD.
You have to be careful not to leave it in standby mode, although it may not seem like it, there will be what is called ‘ghost consumption’. In standby mode the electricity consumption is low, less than one watt. The screen saver that uses less energy is the black one.
9. – Microwave
Use a microwave oven instead of a conventional microwave It provides 60% energy saving. In addition, because they are very fast in their functions, they work in a very short time.
10.- Small household appliances
In this section there is room for devices of a wide variety of structures, whose energy consumption reflects very large differences.
Those that produce heat are the ones that consume the most, Because they have very high power, such as a 1,500-watt iron or a 1,200-variety hair dryer. The food processor beats them with 1,950 watts of electrical power.
