Comparing laptop and desktop electricity costs on bills
Comparing laptop and desktop electricity costs on bills
The expense for one or two cases of beer each year.
For example...
My small HTPC, matching the power consumption of a very basic laptop.
Stays idle at about 11.5 watts.
My main PC operates at roughly 60 watts.

Applying the Electricity Bill Calculator from RapidTables at $0.12 per kWh:
Running idle 24 hours a day for a year:
The HTPC would cost $12.62 annually.
The main PC would cost $63 annually.
This results in a total difference of $51 each year.
If you instead considered 8 hours of daily use...
HTPC - $4.20
PC - $21
That gives a yearly expense of $17.
A difference of $17, which is smaller since office tasks don’t heavily tax a desktop’s idle power draw.
A lower-end desktop should consume roughly 30 to 40 watts, but you must also consider the monitor, which adds another 10 to 15 watts. A laptop used for office tasks, such as a Dell XPS or Inspiron, usually uses about half of that if it's fully charged and plugged in.
