How to use the Standby Power Aggregator
The Formula
Daily kWh = Σ (standby W × quantity × 24 h) ÷ 1,000. Annual cost = daily kWh × 365 × your $/kWh rate. Modern devices draw watts even when screens are off—chargers, converters, and instant-on TVs are common culprits.
Practical Example
Smart strips and switched outlets can eliminate most always-on draw. Pair this audit with Smart Thermostat Savings for HVAC waste and LED Savings ROI for lighting upgrades.
