Since they are built to run on a battery and are more energy-efficient than desktop computers, laptops, notebooks, and netbooks often consume less power than these devices. In addition, strong video cards are uncommon in laptops; instead, integrated graphics are frequently used, which uses less power. The power consumption of a laptop varies depending on the size of the screen; normally, power consumption ranges from 20 watts to 100 watts when using a battery. We estimate that a 14 to 15-inch laptop will typically use 60 watts of electricity while plugged in, with an increase of 10 to 20 percent when the battery is being charged.

To get the energy usage of a 14–15-inch laptop that consumes 60 Watts when plugged in for 6 hours per day at a cost of $0.10 per kWh, click calculate.

Utilization of electricity by a laptop, notebook, or netbook

items
Hours a day

Hours Used Per Day: Indicate the average number of hours per day that the device is used. If the daily power usage is less than one hour, enter the number as a decimal (for instance, 30 minutes a day equals 0.5).

Power Use (Watts): Type in the watts that represent the device's typical power use.

Price (kWh): Enter the price per kilowatt hour you pay typically; our calculators use a default value of 0.10 (10 cents). Check your power bill for the precise cost.

If you're interested in computers with lower power consumption and high mobility, laptops, notebooks, and netbooks are wonderful options. Your portable computer will use less energy if you enable power-saving options like sleep or standby modes, similar to desktop PCs.
