Editorial Process
How EnergyTools content is researched, drafted, fact-checked, and published. The independence pledge, the data sources, the correction policy, and the monetization disclosure, all in one place.
For the math behind our calculators, see ourData Methodology page.
Our Independence Pledge
EnergyTools is an independent solar research site. We do not accept paid placements from installers in editorial content. Affiliate relationships (including the optional EnergySage referral) are disclosed separately and do not move a single number on this site. A site that monetizes the moment you click "calculate" has an incentive to inflate savings and shorten payback. We have no such incentive: our calculators exist so you can pressure-test the very quotes those other sites and installers generate.
Every calculator on this site runs entirely client-side, in your browser. The inputs you type (your ZIP code, your bill, your roof) are used to compute a result on your own device; we do not store them, sell them, or share them with third parties. Where we offer an optional connection to an installer, it is exactly that: optional, and never a precondition of seeing a result.
The 5-stage editorial workflow
Every long-form page on EnergyTools moves through the same pipeline before it ships. The point of writing it down is that you can hold us to it.
- 1
Research and data gathering
Every article starts with primary sources, not opinion. We pull residential rates from EIA Table 5.6.A and NREL Utility Rates V3, solar production from NREL PVWatts V8, incentive rules from DSIRE and the state PUC dockets, vehicle efficiency from EPA FuelEconomy.gov, installed-cost benchmarks from LBNL Tracking the Sun, and federal tax-credit rules from IRS and U.S. Treasury guidance. The raw figures go into the single-source-of-truth JSON files in src/data/ that also drive the calculators, so an article and a calculator can never disagree about the same number.

AI-assisted first draft
EnergyTools uses AI tools to produce the first draft of an article. We say that plainly here, in line with the Editorial Process Attribution signal that search engines began rewarding after the July 2026 Core Update. AI is a drafting tool, not a publisher. It does not get the final word on any claim that appears on the site, and no page goes live on an AI draft alone.

Human fact-check
A human editor reviews every numerically load-bearing claim against the primary source. Rates are checked against the EIA and NREL pulls cited above; incentive figures are checked against the current DSIRE record or PUC order; payback and savings numbers are checked against the same JSON SSOT that the calculator code reads. Anything that cannot be traced to a primary source is either removed or rewritten as an explicitly labeled illustrative example. Errors found at this stage are corrected before publication, not after.

SEO optimization and unique media
We structure articles for search: descriptive title and meta description, internal links to the relevant calculator and to neighboring articles, schema.org structured data (Article, BreadcrumbList, FAQPage where applicable), and original charts or tables rather than stock photography. We do not stuff keywords, and per DESIGN.md we do not use generic hero sections, AI-purple gradients, or fabricated benchmarks. The goal is for a search engine and a human reader to see the same useful page.
- 5
Publisher review
Before publication, the page is signed off by the editorial team led by Jeremy Wolfe (Senior Solar Energy Analyst). The reviewer confirms the sources, the math, the disclosure language, and the design tokens one more time. If a correction is needed later, we update the page, bump dateModified in the Article schema, and note the change on the affected page. The site is maintained; pages are not abandoned.
AI is used at the drafting stage (Stage 2). It is never the only voice on the page. The fact-check (Stage 3) and the publisher review (Stage 5) are both performed by a human editor, and any claim that cannot be traced to a primary source is removed before publication.
Data sources we use
These are the same primary sources that feed the calculators, framed here as editorial provenance: every figure that appears in an EnergyTools article should trace back to one of these datasets. For the math itself, see the Data Methodology page.
| Source | What we use it for |
|---|---|
NREL PVWatts V8 pvwatts.nrel.gov | Hourly-to-annual solar production (kWh) from latitude/longitude and system specs. |
NREL Utility Rates V3 developer.nrel.gov | Residential, commercial, and industrial electricity rates by location. |
U.S. Energy Information Administration (EIA) eia.gov | Table 5.6.A residential electricity price data and retail-rate trend context. |
DSIRE dsireusa.org | State and local incentive catalog (rebates, tax credits, exemptions). |
EPA FuelEconomy.gov fueleconomy.gov | Vehicle efficiency (kWh per 100 miles) for the Solar + EV Calculator. |
LBNL Tracking the Sun emp.lbl.gov/tracking-sun | Residential PV pricing and system-characteristic trends for cost-per-watt validation. |
IRS / U.S. Treasury irs.gov | Section 48E guidance, OBBBA tax-credit rules, and Foreign Entity of Concern (FEOC) rules. |
State Public Utility Commissions naaruc.org | Utility tariff filings, net-metering dockets, and approved rate cases. |
Google Geocoding developers.google.com | ZIP code to latitude/longitude resolution for NREL API calls. |
Correction policy
If we publish something wrong, we fix it and note the change on the affected page. When a numeric error is confirmed, we update the figure, refresh the source citation if needed, bump dateModifiedin the Article schema, and add a short correction note at the bottom of the page describing what changed and when.
To report an error, email hello@renewestimator.comwith the page URL and the value in question. We review every report and reply once a correction is published or the figure is confirmed correct.
How we make money
EnergyTools is funded by two revenue streams, both disclosed in full here and kept strictly separate from editorial content:
- Optional solar installer referrals. On some pages we offer a connection to a local installer. Clicking it is always optional and never required to see a result. The installer pays us only if you actively request and complete a quote.
- EnergySage affiliate relationship. Where we link to EnergySage, we may earn a referral fee. That relationship does not influence our payback estimates, cost-per-watt figures, or any editorial rating.
No installer pays for a favorable editorial rating or page placement. The payback, savings, and cost-per-watt numbers we publish come from the same JSON SSOT and the same government data sources regardless of whether a given state's installer happens to be in our referral network.
