Energy Factbook
Every figure is dated and sourced · Site updated August 14, 2026
The average American household pays 18.44¢/kWh for electricity and $135.70 a month, as of May 2026. Regular gasoline averages $4.01 a gallon. The United States produced 107.0 quadrillion Btu of energy in 2025 and consumed 96.3. Across the 35 metropolitan areas EPA charted in its last national air trends report, unhealthy-air days are down 80% since 2000 on a single fixed definition of unhealthy. Each of those numbers comes from a different agency on a different schedule, and each one here is labeled with the period it covers.
What are you trying to find out?
What does energy cost where I live?
Residential electricity rates and average bills for every state, and for 205 utilities you can find by ZIP code. Gasoline by state, heating cost by fuel, and whether a heat pump, rooftop solar or an electric car actually saves money where you are.
Where does U.S. energy come from?
Production, consumption, electricity generation by source, trade and carbon dioxide, from the EIA Monthly Energy Review. Includes the long emissions record back to 1970.
How does the United States compare with other countries?
Household electricity and gasoline prices across 79 countries, the energy and electricity mix of every major economy, and who produces the most oil, gas and coal.
Is American air getting cleaner?
Yes, and by more than the official scorecard shows, because EPA changed what an Air Quality Index of 100 means. Unhealthy-day counts for all 50 states, the District of Columbia, Puerto Rico and 456 metropolitan areas, scored under both the current rules and the pre-2013 rules, plus three investigations into what the air quality standards did and did not deliver.
The data behind this week’s energy stories
Week of August 14, 2026 · Each headline links its primary source; each “the data” link is a reference page we maintain year-round.
- EIA reports oil flows through the Strait of Hormuz down 77%, and flags its own tracking data as unreliable (EIA Global Energy Security Data, Aug 12)
- EIA forecasts record U.S. natural gas production of 122.5 billion cubic feet per day in 2026 (EIA Today in Energy, Aug 12)
-
After Texas announced a pause on new data-center development, EIA cut its 2027 Texas electricity-demand growth forecast from 14% to 6%
(EIA Short-Term Energy Outlook, Aug 11)
- The data: Why is my electric bill so high?
Look something up
- By ZIP code — your own utility's average rate
- By state — electricity rates and average bills
- By metro area — air quality for 456 metros
- By country — energy profiles for 79 countries
Worth reading
- What the Hormuz numbers can and cannot tell you. EIA reports strait flows down 77% while world supply fell 4%. Why the 2026 transit figures measure tanker tracking, not barrels.
- Why is my electric bill so high? Three drivers you can check on your own bill, and the data-center demand growth behind rising rates.
- Why are gas prices high right now? What a gallon is actually made of, and how much of it is crude oil.
- Why has ozone stopped improving? Emissions kept falling and ambient ozone stopped responding. What the data show, and what we could not explain.
Where these numbers come from
Everything on this site derives from official government and statistical sources: the U.S. Energy Information Administration, the Environmental Protection Agency, Eurostat, the European Commission Weekly Oil Bulletin, the Census Bureau and AAA. Every page states the period its data covers and links the source. Nothing here is modeled or forecast by us; where a figure is EPA's or EIA's own projection, it says so.
When a source revises a number, the change is logged publicly on data updates. The exact source, formula and publication lag for every figure is on methodology. Air quality carries its own method and corrections page, including the errors we have found in our own analysis.
