About Voltlas

Voltlas tracks the price of energy — and the fuels and materials that power it — across the world, in one clean, free place. Every figure is pulled from an official source that permits public republication, converted to US dollars, and labeled with its origin and date. It covers retail electricity and natural gas, petrol and diesel at the pump, and benchmark commodities, with coverage strongest across Europe and North America.

How it works

Prices are all-taxes-included end-user figures wherever the source provides them, stored in their native form and converted to USD at recent reference exchange rates. Automated connectors re-pull every source on a weekly schedule, so the numbers stay current without manual work. Each price carries its source and the period it represents — and where no free official source exists, the country or commodity is simply left out rather than estimated. The goal is a figure you can trust and trace, not the widest possible coverage.

Independent & ad-free

Voltlas is an independent project — founded, built, and maintained by Fela Odeyemi, Ph.D, a power-sector engineer based in the San Francisco Bay Area. There are no ads, no paid placements, and no licensed or proprietary data feeds — just public official data, presented plainly. That independence is the point: the value here is trustworthy numbers from sources you can verify yourself.

Where the data comes from

Using the data

The underlying figures come from public official sources; Voltlas compiles and presents them. You're welcome to reuse the compiled data under a Creative Commons Attribution 4.0 license — reuse it freely, just credit Voltlas and link back. Please also check each original source's own terms where relevant.

Contact & corrections

Spotted a number that looks wrong, a source that's gone stale, or have a suggestion? That feedback is genuinely useful and helps keep the data honest. Email hello@voltlas.com — for corrections, it helps to include the country or commodity and what you'd expect to see.
