Household energy use
Add at least one device to estimate a household energy breakdown.
Method and boundaries
Each device uses the TOOL-011 period model. Total energy is the sum of device kWh; share is device kWh divided by total kWh.
This estimate uses nameplate power, use hours and duty factors entered by you. It is not measured household-meter data or a utility bill. No time-of-use rates, fixed charges, demand charges, taxes or billing rules are inferred. Currency is a label only; no conversion occurs.
Method and boundaries
Each device uses the TOOL-011 period model. Total kWh is the sum of device use; each share is device kWh divided by total kWh. If total use is zero, every share is zero and the page says “No energy use.”
This is a nameplate-based estimate, not measured household-meter data or a utility bill. Time-of-use rates, fixed charges, demand charges, taxes and utility rules are not inferred. Currency is user-selected and no exchange conversion occurs. SRC-010 · model 1.0.0 · user-input-v1.
