Method, inputs, and worked result

Method

  1. 1Identify incremental equipment use.
  2. 2Convert measured watts and hours to kWh.
  3. 3Keep tax or reimbursement eligibility separate.

Inputs used

  • 65 W laptop, 35 W monitor, 10 W lamp
  • 22 workdays with stated hours
  • $0.18 per kWh

Worked example

Laptop and monitor run eight hours daily; lamp runs six.

  1. 1.Laptop uses 11.44 kWh and monitor 6.16.
  2. 2.Lamp uses 1.32 kWh.
  3. 3.18.92 kWh x $0.18 = $3.41.

18.92 kWh and $3.41 incremental device electricity.

Reproduce: Measure devices on representative workdays and rerun with logged active hours.
