How Appliance Energy Costs Are Calculated
Top Energy-Saving Actions

Coût par Appareil

Formule : watts × h/jour × 365 ÷ 1 000 × prix/kWh. Réfrigérateur (150W continu) : ~230 kWh/an = ~40 €. Sèche-linge (3 000W × 1h × 150 cycles) : 450 kWh = ~77 €. Chauffage/clim : 46% de la facture totale — c'est le poste à optimiser en priorité.

Les Plus Gros Postes

Chauffage/clim : 46%. Eau chaude : 14%. Gros électroménager : 13%. Éclairage : 9%. Le passage aux LED et l'isolation sont les investissements les plus rentables. Un audit énergétique (100-300 €) identifie les priorités.
