Energy guide calculations
Appliance electricity cost estimates represent standard engineering calculations based on appliance power ratings:
• Wattage (W): The rate at which the appliance consumes electrical energy when active.
• Kilowatt (kW) conversion: Wattage ÷ 1,000.
• Electricity Draw: kW × running hours.
• Final Cost: kWh × electricity rate per kWh.
• Kilowatt (kW) conversion: Wattage ÷ 1,000.
• Electricity Draw: kW × running hours.
• Final Cost: kWh × electricity rate per kWh.
Note that complex cooling systems like refrigerators and air conditioners do not run at full power draw continuously; they cycle their compressors on and off based on thermostats. Our dashboard modeling implements duty cycle estimations to provide realistic bills matching your actual utility invoicing.
