Determine the Wattage: Check your refrigerator’s user manual or the specifications label usually found inside the fridge door.
Calculate Daily Usage: Use this formula:
Daily Usage (Wh) = Wattage x Hours of OperationFor example, a refrigerator that uses 300 watts running for 24 hours a day would consume:
300 W x 24 h = 7,200 Wh (or 7.2 kWh).Monthly Consumption: Multiply the daily usage by 30 to find the monthly usage:
Monthly Usage (kWh) = Daily Usage (kWh) x 30Continuing with our example:
7.2 kWh x 30 = 216 kWh per month.Calculate Energy Costs: To find your electricity cost:
Monthly Cost = Monthly Usage (kWh) x Cost per kWh.- For instance, if your energy provider charges $0.10 per kWh, your cost would be:
216 kWh x $0.10 = $21.60.
Energy-Saving Tips for Your Refrigerator
Using your refrigerator efficiently not only saves energy and money but also extends its lifespan. Here are some practical tips for maximizing your refrigerator’s efficiency:
