Формулата за Цената
Цената на електроенергията е просто консумираната енергия, умножена по цената на вашето електроразпределително дружество за kWh.
Дневна Цена
Cost = kWh × Rate ($/kWh) Умножете дневното потребление в kWh по вашата тарифа за електроенергия, за да намерите дневната цена на работа на всеки уред или система.
Годишна Прогноза
Annual = Daily Cost × 365 Годишното изчисляване на разходите разкрива истинското въздействие на привидно малките ежедневни разходи — и улеснява обосноваването на подобрения за пестене на енергия.
How to Calculate Your Electricity Cost
Understanding exactly what each appliance costs to run empowers smarter energy decisions — from choosing when to run the dishwasher to calculating the payback period on a new heat pump. The calculation is straightforward: find the power in kW, multiply by hours of operation, and multiply by your electricity rate per kWh.
Finding Your Electricity Rate
Your electricity rate ($/kWh or p/kWh) appears on your utility bill — look for "energy charge" or "unit rate." In the US, the average residential rate is around $0.12–$0.16/kWh, but it varies widely by state and time of day (time-of-use tariffs). In the UK, the Ofgem price cap sets a standard unit rate. Always use your actual rate for precise calculations.
Biggest Contributors to Your Electricity Bill
- Space Heating / Cooling (40–50%): Heat pumps are 3–4× more efficient than resistance heaters — replacing old electric baseboard heaters can cut this portion dramatically.
- Water Heating (15–20%): Heat pump water heaters use 60–70% less electricity than conventional electric tank heaters.
- Appliances and Lighting (10–15%): LEDs and Energy Star appliances provide the biggest savings here with shortest payback periods.
- Electronics and Standby (10%): Smart power strips and unplugging devices cuts phantom load — small savings that add up over a year.
Time-of-Use Pricing Tips
Many utilities offer time-of-use (TOU) tariffs with cheaper rates during off-peak hours (typically late night and early morning). Shifting energy-intensive tasks — EV charging, running dishwashers and laundry, pre-cooling your home — to off-peak hours can reduce your bill by 20–40% without reducing consumption at all.
