How is standby waste estimated?

The tool combines standby power, daily standby hours, and your electricity tariff to estimate annual cost per appliance.

What does minimal-disruption mode do?

It filters opportunities to prioritize actions that are easier to implement while still delivering meaningful savings.

Does intervention cost affect ranking?

Yes. Payback and priority can change when hardware or setup cost is included.

Can I use this for UK households?

Yes. It is designed around UK-style tariffs and household usage patterns.

How often should I re-run it?

Re-run after tariff changes, appliance upgrades, or major routine changes that affect standby hours.
