Frequently asked questions
Where do the gas and diesel prices come from?
The US Energy Information Administration surveys retail stations every Monday and publishes national averages. This page reads them straight from EIA (weekly retail price series). They include taxes and are averages, so your local price can differ.
Why is my electric bill rate different from the state average?
EIA averages divide each utility's revenue by its sales, which folds fixed charges into the per kWh number. Your rate depends on your utility, plan and usage tier.
What counts as natural gas in the power mix?
Natural gas plus other fossil gases. Solar includes estimated rooftop solar. Wind and other renewables is mostly wind, with biomass and geothermal.
Are the data center numbers live?
No. They are published estimates from LBNL, EPRI and EIA, shown with their scenario ranges and dates. They change when a new report comes out.
How often does this update?
Daily. Gas and diesel post weekly on Mondays, Henry Hub daily with a short lag, and electricity prices and generation monthly with about a two month lag.
