Explore the data
Each tool keeps its state in the web address and draws a picture of the result with the source printed on it, so a friend opens the same view.

How the tools work
Everything runs in your browser from small JSON files stored next to the pages. Nothing you type leaves your device, there is no account and no tracking. The address bar after the # sign holds your choices, so copying it shares exactly what you see. The PNG button draws the current result on a card with its source line.
Data comes from public files: EIA retail sales and the EIA-861 survey, Census ACS 2023, FEMA National Risk Index, DOE LEAD, NOAA Storm Events and degree days, EPA eGRID and NREL PVWatts. See data sources and the method and limits.
Questions
Do these tools send my ZIP code anywhere?
No. The ZIP lookup is a file the page downloads once; matching happens on your device. The page has no server-side lookup; what you type is never sent to us. Site-wide analytics is described on the privacy page.
Why does the address change when I use a tool?
The part after the # sign stores your choice, such as the metric, the state or the year. Copy the address to share the same view. Browsers do not send this part to any server.
Where do the numbers come from?
From the same data files that feed the state, utility and county pages, listed on the data sources page. Nothing here is typed in by hand or taken from a survey of our own.
Are the prices what I will pay?
No. Prices are annual averages from EIA data. In states where you choose a retail supplier, a plan price can differ a lot, so those pages show who delivers power and how to pick a plan instead of a supplier price.
Can I embed or reuse a result?
The PNG you download is yours to post. Our tables are CC BY 4.0: credit Electric Consumer and the agencies named on the card. The CSV links on each page give the full tables.
Do the tools work on a phone?
Yes. They are laid out for a 390 pixel wide screen, every control works with the keyboard, and the same figures are also in plain tables on each page.
