How many kWh does a house consume per day?
According to Red Eléctrica Española (REE), the average monthly consumption of a household in Spain is 270 kWh, which gives an average annual consumption of 3,272 kWh. The Institute for the Diversification and Saving of Energy (IDAE) puts the figure at 3,487 kWh in its report on Consumption in the Residential Sector in Spain (2020-2019). This document gives us a very clear idea of electricity consumption in Spanish households: of the total electricity consumption, heating accounts for 7.4%, air conditioning, 7.5%. Kitchen appliances account for 9.3% of consumption, while fridges and freezers account for 2.3%. Home lighting accounts for 11.7% of consumption, while the rest of appliances account for 55.2%. Finally, the stand-by function for devices consumes 6.6%.
After analysing consumption for each of the appliances, the report provides us with the following percentages: the fridge consumes 30.6%, while freezers account for 6.1%. The washing machine accounts for 11.8%, while dishwashers account for 6.1% and clothes dryers for 3.3%. Ovens consume 8.3%. TV and other screens account for 12.2% and computers 7.4% The report ends with the consumption of the standby function, which is 10.7%, and other appliances, with 3.5%.
Domestic appliances that consume the most
Leaving aside heating and air conditioning, these are the four domestic appliances that consume the most in your home:
1. The fridge
According to the IDAE report, 99.6% of Spanish households have a fridge. We have seen that it can consume 30.6% of the total energy, because it is an appliance that should always be switched on. It should be taken into account that when the temperature is low, the fridge does not work at full capacity and does not use maximum power. Also, the higher the efficiency labelling, the lower the consumption. According to estimates by the IDAE, a fridge consumes about 655 kWh per year.
According to Statista, 98.6% of Spanish households have a TV. It consumes 12.2% of the total. If we watch television for an average of 228 minutes a day, this represents 1,387 hours of television per year. IDAE estimates that a single TV at home would mean an annual consumption of 119 kWh.
3. Washing machine
As seen above, the washing machine represents 11.8% of total electricity consumption in Spanish homes and 92.9% of these have one. Again, the efficiency of the appliance should be taken into account as this will reduce consumption. Washing in cold or using energy savings programmes is another decisive factor. According to IDAE, washing machines consume about 254 kWh per year.
The National Institute of Statistics (INE) points out that 88.3% of Spanish households have an oven. According to IDAE, ovens account for 8.3% of electricity consumption. The type of oven, how responsibly you use it, its energy efficiency label, as well as the number of hours it is kept on will determine the volume of consumption. It is estimated that every time an oven is turned on for an hour, it uses 1.5 kWh of electricity. If you use the oven for two hours a week, it would consume about 150 kWh per year.
