Our Methodology Standards

All DataWisdom research and reference materials are built on transparent formulas and clearly documented assumptions. We rely on public, authoritative data sources (such as the EIA and Department of Energy) to provide reliable baseline estimates. We do not guarantee exact bills, but we do guarantee exact math.

Update Policy & Corrections

We review our reference models periodically. If you represent a manufacturer, utility, or regulatory body and have found an outdated assumption or calculation issue, please contact us with supporting primary-source information at hello@datawisdom.online.
