Our purpose
WattWise Lab is a small, focused resource for people who want to understand household electricity use. We provide interactive calculators and explanatory guides for estimating energy consumption, comparing scenarios, and understanding the assumptions behind a result.
What makes the tools useful
The calculators allow visitors to enter their own power ratings, hours of use, and electricity prices. They display formulas and limitations alongside results. Calculations run in the browser; the calculator values are not submitted to a WattWise server by the tools.
What we do not claim
We do not claim to know your utility tariff, inspect your home, verify a solar proposal, or predict an exact bill. Our estimates are not engineering advice and do not replace a qualified assessment where safety, electrical work, HVAC design, or a major investment is involved.
