OpenHow this site works
Every price here comes from the U.S. Energy Information Administration and is read straight from its published data when the site rebuilds, so a page never quotes a number someone typed months ago. The calculators run in your browser and keep what you type on your device. Pieces are researched and drafted by AI agents and checked against the sources they cite; how this site is made explains who does what, and the methodology shows every formula.
