(Wattage x eight) Ã· 1000 = kWh per day. Where eight represents our presumed eight hours active time per day. Thus a 600 Watt unit â typical of older, larger refrigerators â would use 4.8 kilowatt hours daily, or 1750 per year; where a more modern 140 watt unit uses about 1.1 kWh daily, or approximately 400 per year.This is how many watts does a refrigerator use.No information is provided by the author.Wattage x eight) Ã· 1000 = kWh per day.
