Do Energy-Monitoring Smart Plugs Actually Save Money?

Problem: "Vampire" loads - idle electronics, old fridges in garages, always-on entertainment centers - are invisible on a monthly bill.

Solution: An energy-monitoring plug measures live watts and cumulative kWh per outlet. Find the load, then automate it off (schedules, presence) or replace the appliance. Typical candidates measured by utility programs: game consoles, cable/set-top boxes, desk printers, garage freezers.

Honest math: a plug drawing 10 W continuous costs roughly $10-13/year at US average residential rates. Monitoring finds these loads; savings come from acting on what you find. A $10-25 plug pays back only if it surfaces a real load you then cut.

Safety: stay within each plug's printed max-load rating (see each model's sourced rating above). Space heaters and other high-draw appliances need 15A-rated plugs and manufacturer approval for switched operation.
