Frequently Asked Questions
How much does phantom load cost the average household?
A whole-home phantom total of 80-120 W is common, costing $110-$170/year at $0.16/kWh. The average US standby consumption is roughly 50 W per home, about $70/year - but modern well-equipped homes can run much higher.
Are all standby devices worth eliminating?
No. Routers, DVRs mid-recording, refrigerators, and medical equipment should stay on. Focus on entertainment and charging clusters where the loss provides little value.
What is the CO2 figure based on?
The default of 0.85 kg CO2 per kWh represents the US average grid emissions factor. The actual factor varies by region - nearly zero for hydro and nuclear-heavy grids, higher for coal-heavy ones.
Does a smart strip eliminate all phantom load?
Only for switchable devices. The always-on outlets (for DVR, router) still draw power. Combined with behavioral changes, smart strips typically eliminate 50-80% of the modeled load.
