the trend of improvement continues

Bern, 05.12.2022 – Freezers, dryers, PCs and dishwashers consume less electricity. This is demonstrated by an analysis of large household appliances and electronic equipment sold in Switzerland, carried out on behalf of the Federal Office of Energy (SFOE). It shows that, in the observed period (2002-2021), the total energy consumption of appliances decreased by 16.3%, despite the simultaneous increase in the number of appliances (+41.2%). . The data comes from the Swiss Association of Manufacturers and Suppliers of Household Electrical Appliances (FEA) and the Swiss Economic Association for Office Automation, IT, Telematics and Organization (Swico).
In 2021, Switzerland will have 49.3 million large household appliances, IT devices, office automation and leisure electronics in use, i.e. 41.2% more than in 2002 (34.9 million ). In total, their electricity consumption reached 6.5 terawatt hours (TWh), or 11.2% of Switzerland’s total electricity consumption. This also represents 1.3 TWh or 16.3% less than in 2002 (7.8 TWh).
Since 2002, computing, office automation and electronic entertainment equipment (PCs, monitors, etc.) have experienced a strong improvement in their efficiency: during this period, their consumption has fallen by 53% . As for refrigerators, freezers and others, they are 32% more efficient than in 2002. The efficiency obtained is equivalent to the theoretical improvement that would be obtained if the number of units was the same in 2021 as in 2002 .
Regarding large household appliances, consumption per appliance calculated separately for all appliances decreased from 387 kilowatt hours (kWh) in 2002 to 271 kWh in 2021. In 2002, electrical appliances consumed an average of around 130 kWh, compared to 47 kWh in 2021 .
Calculated energy consumption values are mainly based on energy label data (eg for televisions) or manufacturer data. Actual consumption may vary if user habits do not match energy label assumptions or if appliances (eg televisions and computers) are subject to atypical use.
Major household appliances (from 2002 to 2021)
- In 2021, more than 18.75 million basic household appliances were used in Switzerland, which is 38.6% more than in 2002 (13.5 million). During this period, their energy consumption decreased by 2.9%, from 5232 million to 5077 million kWh.
- Since 2002, there has been a marked improvement in energy efficiency in all categories of appliances.
- For household appliances, the efficiency gain is around 32%.
- In the main appliance category, the largest electricity consumption was from electric cookers/ovens (1,453 million kWh), refrigerators (1,049 million kWh) and clothes dryers (770 million kWh).
- The new energy labels were introduced in Switzerland in March 2021, with a transitional period until the end of the year. The new labels for refrigerators, washing machines, dryers and screens (televisions, monitors) indicate only categories A to G, as before, without the “+” sign. This development should lead to an improvement in the efficiency of electrical appliances.
Computer equipment, office or entertainment electronics (from 2000 to 2021)
- In 2021, Switzerland will have around 30.5 million large household appliances, IT devices, office automation and electronic pastimes in use, i.e. 51.6% more than in 2000 (20.1 million). Even though, during this period, their power increased and they were used more, their energy consumption decreased by 44.8%, from 2612 million to 1443 million kWh.
- Considering entertainment electronics (TV, video, decoder), energy efficiency recorded a significant increase of 54.7% between 2000 and 2020. However, the share of large television sets (screen diagonal than 32 inches ) increases fuel consumption. These devices consume more energy because they have additional functions.
- In the field of computing, between 2000 and 2021, all categories of devices gained efficiency (+52.5%).
- In 2021, thanks to the achieved energy efficiency, the energy consumption of computer equipment, office or leisure electronics will be 1892 million kWh (or 56.7%) lower than the projections established in 2021. year 2000 in consumption of appliances according to their energy efficiency.
- The sharp decrease in consumption can be explained by technological progress, but also by changes in purchasing behavior (fewer desktop computers, but more laptops and tablets), the introduction of standby requirements and limitations consumption, and the introduction of energy labeling and labels such as ‘Energy Star’.
- The strongest increases in the various device parks since the 2000s are laptops (+5.3 million devices), tablets (+4.5 million devices) and TV decoders (+3 million devices).
- The number of screens continues to increase: in 2021, there were 3.7 million, a number higher than in 2020, a year marked by the coronavirus pandemic (3.3 million). This increase can be explained by the fact that working from home continued after 2020. In 2021, the number of laptops and video projectors also increased.
