The home is occupied during work hours more often, and electric or water usage rose after remote work started.
Work from home can add computer and monitor loads, but HVAC, lighting, cooking, coffee, bathroom use, and daytime comfort settings often matter more than the laptop itself.
Check first
Estimate computers, monitors, docking stations, printers, and lighting.
Compare thermostat schedules before and after remote work.
Check daytime cooking, dishwasher, coffee, and bathroom water use.
Compare daily kWh and gallons rather than the total bill only.
Practical savings moves
Use sleep settings, smart strips, and reasonable monitor routines.
Adjust thermostat schedules for occupied rooms without over-conditioning the whole home.
Estimate office loads separately from heating and cooling.
Track daily usage after schedule changes.
Avoid these mistakes
Do not blame a laptop for a bill mainly driven by daytime HVAC.
Do not ignore fixed fees and rate changes.
Do not make comfort or productivity worse to chase tiny plug-load savings.
