Questions, corrections, and suggestions are always welcome — a real person reads every message.

What to reach out about

  • Data corrections — if an electricity rate, fuel price, or incentive looks outdated for your state, tell us and we’ll verify it against the source.
  • Bugs — a calculator behaving oddly, a broken page, or results that don’t add up.
  • Calculator requests — a clean energy decision you wish you could put numbers on.
  • Press and partnerships — we’re happy to explain our methodology or provide context on how the estimates work.

We typically reply within a few business days. Please note we can’t provide individual financial, tax, or installation advice.
