What is the energy consumption of a refrigerator with a wattage rating of 700 Watts when it is operated for 24 hours a day?
To solve, use the following formula:
Energy Consumption = Power Consumption x Number of Hours Operated
Energy Consumption = Watt/Hours (Wh) or KiloWatt/Hours (kWh)
Power Consumption = Watts (W) or kW (KiloWatts)Number of Hours Operated = Hours (h)For the example above:
Energy Consumption = 700 W x 24 h
Energy Consumption = 16800 W/h
To convert from W/h to kWh/h, remember that 1kWh/h = 1000 W/h
To solve, set up as a ratio and use linear algebra to solve for ?.
