Email us

The fastest way to reach the GreenCalcs team is email:

hello@greencalcs.com

We aim to reply within two business days. To help us help you quickly, please include:

Corrections & data updates

Accuracy is the whole point of GreenCalcs. If you believe a state incentive, electricity rate or tax rule on the site is out of date, tell us — we'll verify it against the primary source (DSIRE, EIA or the IRS) and update it. Verified corrections are usually live within a week.

Press & partnerships

For media questions, data citations, or partnership ideas, use the same address with "Press" or "Partnership" in the subject line and we'll route it to the right person.

What we can't do

We're a calculator and education site, not a licensed installer, tax advisor or financial planner. We can't give individualized tax or investment advice, recommend a specific contractor, or quote you a firm installation price. For those, please consult a licensed local installer and a CPA.
