Energy Consumption Saving 0

If you have received an invoice with a high cost, and you do not understand why, it is possible that you have consumed more energy during that billing period. Therefore, we will give you the keys so that your consumption is not high and in this way reduce the amount of the electricity bill.

The electricity bill is divided into two terms. The power term, which is the contracted power which is a fixed price, and the energy term by which the number of kWh consumed during the billing period are quantified. Therefore, the price of your bill will depend on the kWh consumed in each billing period.

For optimal savings in your home, it is very important to know how much energy each appliance consumes. According to data collected from the OCU (link) the annual consumption of a home is 9,922 kWh and the cost is € 990 per year. Of course, single-family homes consume twice as much energy as flats.

What appliances consume the most energy in our home?

We will not only take into account the consumption in kWh made by each appliance, but also the daily use we give it and its duration.

One of the keys to saving energy in our home is investing in highly efficient appliances. Since although the a priori expense is higher, in the long run we will see it reflected in our electricity bill.

  • Fridge. The refrigerator is the appliance that consumes the most, representing 30% of the energy consumed on your electricity bill. It consumes between 500 to 1000 kWh. If it is a refrigerator with a built-in freezer, it is the one that spends the most on our electricity bill. And the reason is that despite being very efficient, it works 24 hours a day.
  • Vitroceramic. The Vitroceramic is the second appliance that consumes the most, since it is around 2,200 kWh, being twice that of a refrigerator, unlike this one, the use is not prolonged. However, its expense can represent more than 15% of your electricity bill. We will save energy by covering the cooking containers, as well as the smaller the container, the less energy it will consume.
  • Television. The television is one of the electrical appliances that consume less energy, since it is only about 100 kWh, however, its continuous use and more in Stan by state makes it equal to other electrical appliances with higher consumption. The cost of a television is between 12% and 55%, depending on the technology of the screen and its inches. LED technology consumes 25% less than LCD technologies. To save energy it will be essential not to leave it in Stand By function, that is, to turn it off completely. Since in that state it can consume 10% of the energy in the bill.
  • Washer. The washing machine accounts for 11% of the electricity with a consumption between 1,200 kWh and 1,5000 kWh, being one of the appliances with the highest energy consumption. However, and unlike the refrigerator, it does not need to be on 24 hours a day, but on specific occasions. If we want to reduce its energy consumption, we must avoid long-term programs, as well as the use of high temperatures.
  • Oven. The oven, although not for everyday use in many cases, has an energy consumption of 9%, with an average consumption of between 800 and 900 kWh. This is because it is used rarely, but at the time it is used it is a prolonged use. To avoid scares on your electricity bills, avoid opening it while it is turned on since each time it is done, 20% of the accumulated energy is wasted, as well as turning it off before and thus taking advantage of its residual heat.
  • Electric heating. Heating in winter consumes 9% of the total consumption of your electricity bill. That is why you should avoid leaving it on for a long period of hours, as well as insulating the home through the use of fabrics, such as carpets and thick curtains.
  • Microwave oven. The microwave consumes around 800 and 900 kWh, being very similar to the energy consumption of the oven. In some cases, it can suppose a consumption of 7% of the total of the electrical appliances.
  • Dishwasher. The dishwasher has a 6% energy expenditure on your electricity bill with a consumption of around 1,000 kWh. However, each case will depend on the number of people living at that address and the frequency of use. That is why, if there are few, it will always be better to wash by hand.
  • Dryer. As for the dryer, it is usually used more in the winter season, therefore, it has an energy consumption of 3%. It is one of the appliances that consume the least in our home.
  • Air conditioner. The air conditioning has a consumption of about 170 kWh. In summer there is usually an increase in it, which is why you always opt for an efficient device. Avoid leaving it on for a long period of time, as well as giving it night use.
What happens to those who are in a state of "stand by"

According to the Institute for Energy Diversification and Saving (IDAE), between € 7 and € 10 of energy consumption in your home belongs to Stand-by spending.

The “Stand By” function, that is to say, the standby mode is present in many of the electrical appliances that we have in our home. According to a study by the Lawrence Berkeley National Laboratory (LBNL), it determined that between 10 and 20% of the energy consumed each month comes from electrical appliances that are kept on "Stand by" mode.

  • The microwave, in addition to consuming energy in its daily use, also consumes when it is turned off, implying a consumption of 4 W every hour, even up to 25 W if the door is left open.
  • Even if the television is not in operation, if we leave it with the red light, it can consume about 6 W every hour.
  • The desktop computer is one of the electrical appliances that uses the most energy, since in hibernation mode they consume around 21 W per hour, and if it is on and with the screen off it can reach up to 70 W per hour.
  • The laptop in "Stand by" mode can consume about 16 W, as well as 9 W per hour it consumes if it is kept plugged in.
  • Music devices when plugged in can consume about 14 W per hour, even when turned off.
  • Electric coffee makers can consume more than 1 W per hour if you leave them plugged in. A Game Console has an expense of 4 W per hour counting only the device. However, if left in "ready to use" mode it can reach 20 W.
  • Avoid leaving the mobile charger plugged in since that way it continues to consume energy
  • The strips that have several plugs incorporated also consume. Therefore, try to buy those that have a power switch and thus only use it when necessary.

At Lumisa we always want the best for you, and as a summary we will give you some useful tips that will reduce your electricity bill!

  • Buy appliances with an energy rating A.
  • Do not leave electrical appliances in Stan by function. Unplug them when we are not using them.
  • In winter, insulate your home with thick fabrics, carpets or thick curtains.
  • In summer, turn on the air conditioning for a short time and close all doors and windows.
  • Use short and cold programs in the washing machine, as well as fill it to the maximum.
  • Keep the freezer clean, and the fridge at a temperature between 3 and 7 degrees.
