0.17Kwh x 30days = 5.1 Kwatts

But If you run the laptop for eight hours a day(8h/d) then the average power consumption of a gaming laptop is 1360watts/8h and 1.36Kw/8h

1.36 kW x 30 days = 40.8 KW

40.8 KW x 12 months = 489.6 KW

But If you run the laptop for eight hours a day(8h/d) then the average power consumption of a gaming laptop is 480watts/8h and 0.48Kw/8h

0.48 kW x 30 days = 14.4 KW

14.4 KW x 12 Months = 172.8 KW
