Decreases final electricity demand if rebound effects are excluded.
Decreases final energy consumption, if re-bound effects are excluded.
No direct impact on the share of renewable energy sources in the energy mix.
Likely to increase energy independence and energy security.
Likely to reduce Swiss CO2 emissions, impact on global CO2 emissions depends on embodied energy of new appliances.
If older, but still functioning, appliances get replaced on the grounds of energy efficiency, this could increase deposited waste and environmental impacts related to end of life treatment of materials as well as mining of materials for new products
Impact on total costs of the energy transition not well understood.
Efficiency labels and ratings make users more aware of energy use
May improve balance of payments by substituting oil imports by domestic electricity.
May reduce Confederation income from the tax on electricity under the current taxation system.
The indicator concerns electric household appliances.
Modern household appliances often require less energy to provide the same useful service. Especially appliances such as refrigerators and freezers, laundry machines and dish washers, but also TVs are available with much lower consumption than their predecessors.
Based on the energy rating (A+++ to G in EU) the consumer can compare new products based on their typical annual electricity consumption before making a purchase.
• Replacement of old appliances by new and efficient ones is often not economically viable based on saved energy cost and current electricity prices.
• ‘Rebound effects’ may counteract the energy savings from more efficient appliances. The financial savings from lower running costs can lead to purchase of more appliances, or changes in lifestyle (e.g. wash more often).
The appliances annual average electricity consumption includes the electricity used by:
Some appliances as the air conditioning and ventilation systems are expected to have an important expansion. Because of the expected higher temperatures more households will be equipped with this technology. This fact reduces the effect of having more efficient appliances as more appliances are installed. E.g. the average electricity consumed by the air conditioning and ventilation systems was 350 kWh/(year∙household) , while in 2050 it is expected to be 526 – 659 kWh/(year∙household) .
The expected future value ranges for average electricity consumption of the appliances in a household are:
In 2011, the appliances of household consumed an average of 2873 kWh .
