A desktop computer plus monitor typically draws 150–400 watts while in use and 10–30 watts in sleep mode. Daily energy depends entirely on usage hours; remote workers running these 8+ hours daily see noticeable electricity costs.
| Basis | Cost |
|---|---|
| Per hour (while running, 250 W typical) | $0.047 |
| Per day (8 h/day, 5/7 days) | $0.27 |
| Per month | $8.19 |
| Per year | $98.25 |
| Hourly range (small 150 W – large 400 W) | $0.028 – $0.075 |
