How Appliance Energy Costs Work
Appliance electricity cost depends on power draw in watts, operating hours, and local utility rates per kilowatt-hour (kWh).
- Daily Energy: Multiply wattage by daily usage hours and divide by 1,000 to get daily kilowatt-hours.
- Running Cost: Multiply kilowatt-hours by your electricity rate to determine daily, monthly, and yearly expenses.
- Typical Draw: Space heaters and air conditioners use 1,500W to 3,500W, refrigerators average 150W, and LED TVs use roughly 100W.
