The electricity consumption of a refrigerator can vary depending on factors such as its size, age, energy efficiency rating, temperature settings, usage patterns, and the ambient temperature of the room it is placed in. Additionally, the compressor turning on and off during a cooling cycle can impact the hourly consumption.
To give you a rough estimate, a typical household refrigerator in the United States, which is usually between 18 to 20 cubic feet in size and ENERGY STAR certified, might use around 100-400 watts per hour. However, this is just an approximate range, and actual power usage can differ.
To calculate the energy consumption more accurately, you can find the refrigerator's power rating (in watts) on the label or in the user manual. Multiply that wattage by the number of hours the refrigerator runs in a day. For example, if a refrigerator is rated at 200 watts and runs for 10 hours in a day, it would consume 200 watts x 10 hours = 2000 watt-hours (Wh) or 2 kilowatt-hours (kWh) in one day.
Keep in mind that refrigerators are designed to be energy-efficient, especially if they are ENERGY STAR certified. If you are concerned about your refrigerator's energy consumption, consider checking its energy efficiency rating and upgrading to a more energy-efficient model if necessary. Additionally, maintaining proper temperature settings and keeping the refrigerator well-maintained can help optimize its energy usage.
