- Energy use and emissions are hard to judge without context, so comparing common household activities helps show what’s actually big or small.
- The numbers are rough, based on typical usage, and the tool is deliberately simple to show order-of-magnitude differences rather than exact watt-hours.
- Users are invited to give feedback on wrong assumptions, broken components, missing items, or useful features, and the tool may later be expanded to include carbon-emissions comparisons.
