Data Transparency for
Every Energy Decision
Contractors are experts at selling. Data is the expert at saving. We built Clean Energy Home Hub so homeowners can see the real math — before they ever sign a contract.
Why We Built This
When homeowners research solar, EVs, or heat pumps, the first results they encounter are almost always from companies with a direct financial stake in the answer. Installer quote forms, leasing promotions, and dealer inventory pages dominate search results — not independent analysis.
We set out to build something different: 16 completely free calculators grounded entirely in government and academic data. No lead-generation forms hidden behind results. No inflated savings estimates designed to close a sale.
Our tools are used by homeowners, energy consultants, financial advisors, and journalists who need a neutral second opinion before making a five-figure clean energy decision.
- No sign-up required — every calculator is free, forever.
- No hidden data — methodology notes explain every formula.
- No vendor lock-in — results include quotes from multiple installers.
- No stale numbers — data is reviewed against EIA monthly releases.
- No conflicting incentives — affiliate relationships are disclosed inline.
Our Data Sources
Every number in every calculator traces back to a named, publicly accessible government or academic dataset. Here's exactly where we get our data.
Residential electricity rates, monthly consumption trends, and utility-level energy statistics. Updated every month.

Visit sourceA Note on Affiliate Links
Some pages include recommended products (solar inverters, EV chargers, heat pumps) with affiliate links. When you click and purchase, we may earn a small commission at no extra cost to you. This revenue keeps the calculators free. All affiliate relationships are disclosed inline, next to each recommendation. They never influence our calculator outputs or data sources.
