Kosten pro Gerät

Formel: Watt × Stunden/Tag × 365 ÷ 1.000 × Strompreis/kWh. Kühlschrank (150W Dauerbetrieb): ~50-70 €/Jahr. Waschmaschine (200 Waschgänge): ~50 €. E-Auto laden (15.000 km): ~500-700 €. Der durchschnittliche Strompreis in Deutschland: ~0,30-0,35 €/kWh — einer der höchsten Europas.

Sparen

LED-Umrüstung: 30-50 €/Jahr Ersparnis. Stromanbieterwechsel: oft 100-200 €/Jahr. Standby eliminieren: 30-50 €. Effiziente Geräte (A+++): bis 50% weniger Verbrauch als alte. Vergleichsportale wie Check24 und Verivox erleichtern den Wechsel.

⚡ CalcWolf Insight

The Department of Energy estimates that phantom loads (standby power) account for 5-10% of residential electricity use — $100-200/year for the average household. A smart power strip ($25-35) that cuts power to idle devices pays for itself in 2-4 months.
