Calculating Energy Cost: How to estimate the annual electricity cost based on wattage and usage patterns
To estimate the annual electricity cost of a fridge freezer, you'll need to consider both its wattage and your usage patterns. Start by identifying the wattage of your specific model, which can typically be found on the manufacturer's label or in the user manual. Once you have this information, you can calculate the energy consumption in kilowatt-hours (kWh) by multiplying the wattage by the number of hours the fridge freezer is in use each day, then dividing by 1000.
For example, if your fridge freezer has a wattage of 150 watts and you use it for 24 hours a day, the daily energy consumption would be 150 watts * 24 hours = 3600 watt-hours, or 3.6 kWh. To estimate the annual cost, multiply this daily consumption by 365 days and then by your electricity rate per kWh. Assuming an average electricity rate of $0.12 per kWh, the annual cost would be 3.6 kWh * 365 days * $0.12 = $155.52.
However, this is a simplified estimate and doesn't take into account factors such as temperature settings, door openings, and the efficiency of the fridge freezer.
