Stand-by power
Determine the annual energy consumption of household appliances left in standby mode. Standby mode means the device runs continuously, consuming a small amount of electricity. Common examples include televisions, electric ovens, radios, computers, monitors, satellite receivers, and Wi-Fi routers.
Calculate the annual energy consumption of 17 appliances in standby mode, each consuming an average of 4 W. What is the value of the consumed electricity if 1 kWh = 0.19 €?
