Example

A quick way to sanity-check the result

With the example settings of 500 watts for 4 hours a day, the PC uses 2 kWh per day. Actual draw can be much lower at idle and can vary substantially with the CPU, GPU, display, and workload.

Actual electricity use can vary with power settings, thermostat cycling, efficiency, standby use, and how the appliance is operated.
