Watt Wisdom estimates a home's electricity use from your location, equipment and operating habits. A guided walkthrough leads to a free dashboard where you can review the largest loads, check assumptions and compare changes. You can then pay $19 once for this household to save both PDF report formats.
Use it to understand a high electricity bill, estimate a new or planned home before bills exist, document existing and planned loads for a solar conversation, or explore an equipment change. These are planning estimates; they are not measurements of the home.
Have your approximate floor area, location, occupants, and heating, water-heating, cooking and dryer fuels ready. Major equipment labels, operating hours, EV mileage and home-charging share help make the inputs specific. Dated electricity bills are optional but useful for comparison. Mark uncertain details for review rather than inventing specifications.
The time depends on how much equipment you enter and what information you have ready. We have not established a measured completion-time range. Allow time to check the major loads; you can save progress and return later.
Yes. Answers save to your account. Wait for changes to finish saving before leaving; if a save fails, the page provides a retry so your changes are not silently treated as saved.
The site includes a contractor account workflow for separate client projects. The $19 homeowner offer described here covers one household profile. Contact support if you need help choosing the appropriate workflow.
