Study shows setting air conditioners to 26 °C can halve electricity bills compared with 20 °C, especially for high‑efficiency unitsExecutive summary: A study by Papernest revealed that running an air conditioner at 26 °C instead of 20 °C can cut electricity use by about half for an A+++ unit, while a low‑efficiency G‑class device sees smaller but still significant savings. The result highlights a low‑cost behavioural lever for reducing residential electricity demand during heatwaves, with implications for grid stability, consumer expenses, and the market for high‑efficiency cooling equipment. Papernest (research organization), Italian consumers, appliance manufacturers (especially those producing A+++ air conditioners), and energy utilities. Utilities and policymakers may promote temperature‑setting guidelines and incentives for purchasing A+++ air conditioners, while manufacturers could emphasize efficiency ratings in marketing.The Papernest analysis compares electricity consumption of air conditioners set at 20 °C versus 26 °C across efficiency classes, finding that an A+++ unit at the higher temperature uses roughly half the energy of a G‑class unit at the lower setting. For a typical 50 m² space, the savings translate into noticeable reductions in household energy bills during summer peaks. The findings underscore the role of user behaviour and appliance efficiency in managing seasonal electricity demand.Connected developmentsBlocco diesel euro 5, dal 1° ottobre stop alle auto in città: ecco in quali regioniRessourcen und Kosten sparen: Bundestag beschließt Recht auf Reparatur - was bringt's?Open the full case file on Beyond →
