EV vs. Gas: What Driving Actually Costs in Your State
Is charging an EV cheaper than buying gas?
At the U.S. average residential electricity rate and 3.3 miles per kWh, charging an EV at home costs about 5.5 cents per mile, versus about 16.5 cents per mile for a 27-MPG gas car at the national average pump price. The gap narrows with a high-MPG hybrid or expensive electricity; the calculator lets you check your own numbers.
What does it cost to charge an EV at home?
At the U.S. average rate of 18.31 cents per kWh, driving 100 miles uses about 30 kWh, or roughly $5.49. A full charge depends on the battery: a 75-kWh pack at that rate is about $13.73.
Does this include the $7,500 EV tax credit?
No. The federal EV purchase tax credit expired September 30, 2025. This page compares only the cost of fuel, electricity versus gasoline, to drive a mile, not the purchase price, depreciation, insurance, or maintenance of either vehicle.
Oil price shocks since 1973
When was crude oil most expensive?
July 2008, in both nominal and real terms: U.S. refiners' composite acquisition cost averaged $129.03 per barrel that month, $196 in August 2026 dollars. The 1981 peak of $37.48 ($142 real) is the second-highest real reading.
When was crude oil cheapest?
In real terms, December 1998: $9.81 per barrel, about $20 in August 2026 dollars, at the bottom of the 1997–99 collapse. April 2020 came close: $19.32 nominal, and daily futures prices briefly went below zero that month.
What price series is this?
EIA's refiner acquisition cost of crude oil, composite: the average price U.S. refiners actually paid for domestic and imported crude delivered to their refineries, monthly since January 1974 (EIA series R0000____3). The 1973–74 embargo episode alone uses EIA's FOB cost of imported crude, which begins in October 1973. Spot benchmarks like WTI and Brent only begin in 1986, which is why this older series carries the shocks page.
Why show both nominal and real prices?
Because inflation reshapes the story: the 1981 peak looks low in nominal dollars ($37.48) and severe in real ones ($142). Real values deflate by CPI-U (BLS series CUUR0000SA0, all items, U.S. city average, not seasonally adjusted) into constant August 2026 dollars. October 2025 has no CPI value; BLS never published one after the fall 2025 federal funding lapse, so that month is omitted from the real series.
What is happening to oil prices in 2026?
Refiners' composite cost rose from $59.09 in December 2025 to $104.62 in May 2026 (+77%). The rise coincides with the period for which EIA reports Strait of Hormuz tanker tracking became unreliable; see the Hormuz page and the gas prices explainer for what EIA projects next.
OPEC and the World's Oil
What share of the world's oil does OPEC produce?
34.2% in 2025: 34,379 thousand barrels per day of the world's 100,590, counting today's 12 members (Energy Institute Statistical Review). The share peaked at 50.0% in 1973 and bottomed at 26.5% in 1985.
Which country produces the most oil?
The United States, at 21,065 thousand barrels per day in 2025 (20.9% of the world), the highest single-country total in any year of the series back to 1965. Saudi Arabia produced 11,408 and Russia 10,737. The figures count crude oil, condensates and natural gas liquids.
Did OPEC's production fall as its share fell?
No. OPEC produced 29,273 thousand barrels per day in 1973 and 34,379 in 2025, up 17% across 52 years, while the world market grew 72%. The share fell because everyone else grew faster, led by the United States.
Which countries are in OPEC?
As counted in this data, the 12 current members: Saudi Arabia, Iran, Iraq, United Arab Emirates, Kuwait, Nigeria, Algeria, Libya, Venezuela, Republic of Congo, Gabon, Equatorial Guinea. The roster has changed over time: Indonesia, Qatar, Ecuador and Angola were members in the past and are not today, so historical values on this page describe today's members back-cast, not the organization as it existed in each year.
U.S. Gasoline Affordability: Work Time per Gallon
How affordable is gasoline in the U.S. right now?
In August 2026, one gallon of gasoline (all types, U.S. city average, $4.35) cost 8.0 minutes of work at the average private-sector hourly wage of $32.53. The average over every month since 1978 is 7.7 minutes, so gasoline currently takes more work time than the long-run average. Measured this way, August 2026 was cheaper than 36% of all months on record.
How many gallons of gas does one hour of work buy?
7.5 gallons in August 2026, at the national level: $32.53 in average hourly earnings divided by $4.35 per gallon. By state the answer ranges from 4.2 gallons in Nevada to 9.9 in District of Columbia, using each state's median hourly wage (OEWS, May 2025) and its current pump price.
Are gas prices rising faster than wages?
Over the twelve months to August 2026, the U.S. city-average gasoline price moved +26.7% while average hourly earnings moved +3.8%, so the work-time cost of a gallon changed +22.1% (from 6.6 to 8.0 minutes).
When was gasoline hardest to afford?
Measured in work time, the hardest month on record was July 2008 at 13.8 minutes of work per gallon; the easiest was February 1999 at 4.6 minutes. Dollar prices alone cannot show this, because wages more than quadrupled over the same period.
Which measure of gasoline affordability is right?
There is no single right one. Work time per gallon answers a different question than price alone, and a state ranking built on median wages answers a different question than one built on average wages or household budgets. Every figure on this page names its definition and its source month, and no composite index is used.
U.S. Strategic Petroleum Reserve: Current Level and History
How much oil is in the Strategic Petroleum Reserve right now?
The SPR held 283.8 million barrels of crude oil in the week ending September 25, 2026, per EIA weekly data. That is 39.7% of its 714 million barrels of authorized storage capacity.
Why is the SPR at its lowest level since 1982?
On March 11, 2026, President Trump authorized the Department of Energy to release 172 million barrels over approximately 120 days, per DOE's announcement, as the U.S. share of a 400-million-barrel collective action by IEA member countries during the 2026 Middle East supply disruption. DOE executed the program as emergency exchanges. The section above carries the sourced timeline and the measured weekly decline.
Who can order oil out of the Strategic Petroleum Reserve?
It depends on the mechanism. Emergency drawdowns are ordered by the President. The Department of Energy also runs smaller test sales and exchanges, and Congress has directed sales by law, per DOE's release history.
What is the difference between an emergency drawdown, an exchange, and a mandated sale?
In an emergency drawdown, oil is sold after a Presidential order. In an exchange, companies borrow SPR crude and later return it plus additional premium barrels. In a congressionally mandated sale, DOE sells volumes that Congress directed in legislation. All three appear in DOE's release history; the 2026 release is being executed as emergency exchanges.
How fast can SPR oil reach the market?
DOE puts maximum nominal drawdown capability at 4.4 million barrels per day (as of August 5, 2026), and states oil can enter the U.S. market about 13 days after a Presidential decision, per DOE's SPR Quick Facts (13-day figure verified August 30, 2026).
Is the SPR the same as U.S. oil reserves?
No. The SPR is the federal government's emergency stockpile of already-produced crude oil in salt caverns. It is not U.S. proved oil reserves in the ground, and it is not the commercial crude inventory that refiners hold.
What Is a Crack Spread?
What is a crack spread?
A crack spread estimates a refinery's gross margin by subtracting the cost of crude oil from the value of a fixed mix of refined products. It is only a benchmark. This is not refinery profits because it excludes actual crude inputs and product yields, as well as energy, transportation, RIN, and operating costs.
How is the NY Harbor 3-2-1 calculated?
This page uses two barrels of NY Harbor conventional regular gasoline and one barrel of New York Harbor ULSD, converts product prices from gallons to barrels, subtracts three barrels of WTI, and divides by three.
Why can diesel and gasoline cracks move differently?
They are separate product markets. Seasonal demand, inventories, refinery outages and trade can change gasoline or diesel prices even when the WTI leg is unchanged.
Why Are Gas Prices Going Up (and Why So High)?
Why did gas prices go up today?
As of October 6, 2026, the AAA national average for regular rose 0.3¢ from yesterday, to $4.37 per gallon; over the past week it fell 8.7¢. The larger move is the year: $1.24 higher than the $3.13 of a year ago, which the sections above trace to crude oil.
Why is gas so much more expensive in California than in Texas?
State taxes, fuel-blend rules, and refinery and pipeline access, not different crude prices. Crude trades on a world market, so every state pays about the same for it. California averages $6.39 against $3.75 in Indiana, a spread of $2.64. Our gas-prices hub decomposes every state's price into crude, taxes, and everything else.
Do gas prices fall as fast as they rise?
Nearly. From 2020 through August 2026, in the 21 months when the crude in a gallon rose by 10 cents or more, the pump price captured 100% of that increase within the same month. In the 20 months when crude fell by 10 cents or more, the pump price gave back 96% of the decrease. Both figures compare EIA's monthly WTI crude, converted to dollars per gallon, with the monthly average of EIA's weekly pump price. The gap is real but small.
How much of the price of gas is taxes?
About 12% of the national average right now: the federal 18.4¢ a gallon plus a simple average of state taxes of 33.6¢ (Tax Foundation, 2026), or $0.52 of a $4.37 gallon. State rates vary by tens of cents, which is the main reason two neighboring states can differ on the same crude.
Is this the highest gas has ever been? Reader question
No. Regular averaged $4.46 the week of September 28, 2026 (EIA). The record is $5.01, the week of June 13, 2022, so this week is 54 cents below it. Adjusted for inflation (CPI-U, August 2026 dollars), the record belongs to June 30, 2008: $4.09 then is $6.27 today, and the $5.01 of June 13, 2022 is $5.66. Diesel's record is $6.53, the week of September 21, 2026; it is $6.38 this week.
Why isn't the Keystone Pipeline helping keep gas prices down? Reader question
Three reasons. First, Keystone carries crude oil, not gasoline or diesel. It delivers Canadian crude to Midwest and Gulf Coast refineries, and the fuel still has to be refined. Refining margins, not the cost of moving crude, are where product prices move independently of the oil price. Second, the existing Keystone system is already running (about 594,000 barrels a day in late 2025, per operator South Bow); the never-built Keystone XL extension was terminated in June 2021, and as of September 2026 a partial revival is at the planning stage with a decision targeted for mid-2027. Third, pipelines move crude; they do not price it. Crude trades on a world market, Canada already supplies about 3.9 million barrels a day to U.S. refiners, and a Department of Energy study required by the 2021 infrastructure law found the pump-price effect of Keystone XL "inconclusive."
Why aren't we using more of our own oil? Reader question
We use all of it, and we export more petroleum than we import. The United States was the world's largest oil producer in 2025, at 13.6 million barrels a day of crude (Energy Institute Statistical Review 2026). It is a net petroleum exporter, by about 1.6 million barrels a day in 2023 (EIA). The country is also drawing on stored oil: the Strategic Petroleum Reserve fell from 415 million barrels in early March 2026 to 284 million the week of September 25, 2026, after DOE's 172-million-barrel emergency release.
Producers are drilling more, but slowly. EIA projects U.S. crude output at 13.8 million barrels a day in 2026 and 14.3 million in 2027, up from 13.7 million in 2025. Companies are wary of spending billions on wells that only pay off if prices stay high, and prices would fall if the wars end. In the Dallas Fed's second-quarter 2026 survey, the index for expected capital spending next year was zero. One executive wrote that "elevated oil prices are not directly translating into increased production." Asked how much U.S. production would grow in 2027 with oil at $100, the most common answer was a quarter to half a million barrels a day.
The U.S. produces more oil than any other country. Why doesn't that keep gas cheap? Reader question
For most of the past decade, it did. U.S. crude output rose from 5.0 million barrels a day in 2008 to 12.3 million in 2019 and 13.6 million in 2025 (Energy Institute). That growth is why OPEC's share never recovered, and it brought lower prices worldwide: crude averaged about $99 a barrel in 2011–2014 and $53 in 2015–2019 (EIA refiner acquisition cost).
But oil trades on a single world market, and two wars are now hitting the world's #2 and #3 producers. Saudi Arabia (#2) ships its oil through the Strait of Hormuz, as do Iran (#5), Iraq (#6), the UAE (#8), Kuwait (#10), and Qatar (#13). Together, the Middle East produces 31% of the world's oil. Russia (#3) is at war in Ukraine and under sanctions. When that much supply is disrupted, every barrel costs more, including American barrels, because U.S. producers can sell to buyers anywhere in the world. U.S. production helps, and prices would be higher without it, but it can't replace the Gulf and Russia.
How do gas prices in Canada compare with the United States, in U.S. dollars? Reader question
Canada publishes its average monthly, so the latest comparison is August 2026. Canadian regular averaged C$1.738 per litre (C$6.58 per gallon), or $4.69 a gallon in U.S. dollars. U.S. regular averaged $4.06. Canadian drivers paid about 63 cents a gallon more, or about 15%. Sources: Statistics Canada table 18-10-0001 for self-serve regular, converted at European Central Bank reference rates; EIA weekly prices for the U.S., averaged over August. Both countries pay the world price for crude, so the gap comes from what is added after the crude: taxes, refining, and distribution. The U.S. national average is $4.37 as of October 6, 2026 (AAA). See gasoline prices by country for more comparisons.
Why are gas prices so high right now? Reader question
There are several reasons, but the biggest are two wars: the conflict in the Middle East and Russia's war in Ukraine. Together they have cut both the oil moving around the world and the gasoline and diesel refined from it. Six of the world's 10 largest oil producers are at war or ship their oil through the Strait of Hormuz: Saudi Arabia, Russia, Iran, Iraq, the UAE, and Kuwait (Energy Institute, 2025 production). Three of the eight largest refining countries, Russia, Saudi Arabia, and Iran, are involved in those two conflicts (2025 refinery throughput), and Ukrainian drones have hit a Russian refinery about once every three days this year (IEA).
Before this year the oil system had some slack: spare production in the Middle East, spare refining capacity, and fuel in storage. The wars have used a lot of it up. U.S. refineries are running flat out, refining margins are well above normal, and crude is about 46% of the price of a gallon.
Crude oil prices fell. Why is gas still going up? Reader question
Crude oil prices have come down, but crude is only part of the story. U.S. crude (WTI) peaked at $107 a barrel on September 15, 2026 (EIA) and fell for five straight sessions to about $90 by September 23 (Trading Economics). That is still about 38% above 2025's average of $65 (EIA).
The bigger factor right now is refining, and the refining market is very tight. U.S. refineries have run at 96% to 98% of capacity almost every week since July, against an average of 91% in 2025. The wars in the Middle East and Ukraine have cut refinery output abroad, so there is little slack anywhere, and the buffers are thin: U.S. diesel inventories on September 11 were the lowest for that week of the year in EIA records going back to 1983. With no spare refining capacity and low stocks, refining margins stay high even as crude oil production increases.
When will gas prices go down? Reader question
Gas prices will fall when the oil market is under less pressure, and right now it is under a lot. Six of the world's 10 largest oil producers are at war or ship through the Strait of Hormuz, and Russia's refineries ran at their lowest level since 2004 in June after Ukrainian drone strikes (IEA). Until those supplies recover, prices will be slow to come down.
EIA doesn't give a date for gasoline prices to fall, but it does project a decline. In its September 2026 Short-Term Energy Outlook, EIA expects regular to average $3.35 in 2027, down from $3.84 for 2026 as a whole. It expects Brent crude to fall from $91 a barrel to $74. That forecast assumes Middle East oil returns gradually: EIA expects "some constraints to exporting oil from the Middle East will persist through the end of the year," which keeps the region's production "below pre-conflict averages until the second quarter of 2027."
Producers see the timing the same way. In the Dallas Fed's second-quarter 2026 survey, one executive expected oil to "settle back to around the $70-per-barrel range" 90 to 120 days after the conflict ends. Pump prices follow crude in both directions: since 2020 they have given back 96% of crude's declines, usually within a month (see "Do gas prices fall as fast as they rise?" above).
CENTCOM says 1 billion barrels of oil have moved through the Strait of Hormuz. Why is gas still so high? Reader question
On September 19, 2026, CENTCOM said the military had supported the transit of 1 billion barrels of oil through the Strait of Hormuz over the past two months, not the past two days (Fortune). That works out to roughly 16 to 17 million barrels a day. Before the war, the strait carried 21.6 million barrels a day of crude and products (EIA, late 2025). Even taken at face value, that is about three-quarters of normal, and independent monitors say shipping remains well below prewar levels. Iran's own exports are at zero under the U.S. blockade. Still, more oil is moving than in the spring, when EIA measured 4.9 million barrels a day.
That is only part of the story. The other part is Russia's war on Ukraine. Ukraine has been striking Russian refineries and oil infrastructure with drones, hitting a refinery about once every three days in the first eight months of 2026, according to the IEA. Russian refineries processed 3.8 million barrels a day in June, down 30% from a year earlier and the lowest since 2004, and Russia has banned exports of gasoline, diesel, and jet fuel (Oil & Gas Journal). Those losses come on top of the oil and fuel missing from the Middle East, which leaves the global market very tight.
Why are oil companies allowed to raise prices when supply is short and demand is strong? Reader question
Because the alternative is worse. When less oil is available, something has to decide who gets it. A higher price does that: it gets drivers and businesses to use a little less, and it pays producers, refiners, and importers to bring in more supply as fast as they can. The real choice is who makes those decisions: buyers and sellers, or bureaucrats.
The United States has tried letting bureaucrats set prices instead of buyers and sellers, and it was ugly. Price controls on oil "began in 1971 as a 90 day expedient to control inflation" and lasted a decade. They brought gas lines, and "after the elimination of price controls, the real price of gasoline fell for over two decades" (James Griffin, IER). Controls also "lead to lower supplies in future emergencies," because no one gets paid to hold spare inventory. Price-gouging laws are emergency price controls, and they hurt the people they are meant to protect: when a capped price creates a shortage, "higher income households will inevitably have the upper hand over lower income households," and more so when government controls prices (Jeffrey Miron, Cato).
How much was gas at the pump in 2025? Reader question
Regular gasoline averaged $3.10 a gallon in 2025 (the average of EIA's 52 weekly national prices). That was the lowest annual average since 2021 (EIA). Prices then climbed in 2026: the national average was $4.37 on October 6, 2026 (AAA), 39.4% higher than the $3.13 of a year earlier.
Why aren't we drilling more of our own oil? Reader question
U.S. producers are drilling more, but slowly. U.S. crude oil production has been:
- 13.27 million barrels a day in 2024 (EIA)
- 13.66 million barrels a day in 2025 (EIA)
- 13.71 million barrels a day in 2026, averaging January through June (EIA)
EIA projects 14.3 million barrels a day in 2027 (Short-Term Energy Outlook). A challenge is that companies are wary of spending billions on wells that pay off only if prices stay high. In the Dallas Fed's second-quarter 2026 survey, the index for expected capital spending next year was zero.
My state has lots of oil wells. Why isn't our gas cheaper? Reader question
A state's oil wells are just one step in the process. After crude oil is produced, it has to be transported and refined. What makes one state's gas cheaper than another's is what gets added after the crude: state taxes, fuel-blend rules, and how far the fuel travels from a refinery.
The top oil states show it. As of October 04, 2026 (AAA):
- Texas, the largest producer (5.8 million barrels a day in 2025), has the 3rd cheapest gas, $3.91.
- New Mexico, the second-largest (2.2 million barrels a day), pays $4.35, close to the national average of $4.46.
- Alaska produces 0.4 million barrels a day and has the lowest state gas tax in the country (8.95¢ a gallon), yet it has the 6th most expensive gas, $5.04.
- California, the eighth-largest producer (0.3 million barrels a day), has the most expensive gas in the country, $6.39, with the highest state taxes and its own fuel-blend rules.
Our gas prices by state page breaks every state's price into crude, taxes, and everything else.
Where can I find gas prices for my town or county? Reader question
This site doesn't have local prices; each state page carries the statewide average. GasBuddy.com lists station prices by city, for example Toccoa, in Stephens County, Georgia.
Why Is Diesel More Expensive Than Gas (and Why So High)?
Why is diesel more expensive than gas?
Three structural reasons and one 2026 reason. Structurally, per EIA: distillate demand is strong at home and abroad, ultra-low-sulfur diesel costs more to make, and the federal excise tax on diesel is 24.4¢ a gallon against 18.4¢ on gasoline. In 2026 the gap widened far past those causes: the IEA reports that the drop in Russian middle-distillate exports sent regular buyers scrambling for alternative supply and bidding up diesel cracks, while U.S. refineries were already running near capacity. Diesel is $6.32 against $4.37 for regular as of October 6, 2026, a gap of $1.95.
Was diesel always more expensive than gasoline?
No. In EIA's weekly survey, diesel averaged less than regular gasoline in 5 of the years from 1994 to 2005; every full year from 2005 on has averaged higher. This year's average gap so far, $1.19, is wider than any full year in the series; the previous record was $1.04 in 2022.
Why is the U.S. exporting diesel during a shortage?
Because the shortage is global and buyers abroad are bidding for replacement barrels. The United States was the world's largest diesel exporter in 2025 (Kpler data via Reuters), and with Russian and Gulf supply cut, its exports rose further: EIA's weekly data show U.S. distillate exports averaging 1,672 thousand barrels a day from June 26, 2026 to September 18, 2026, against 1,317 in the same weeks of 2021 to 2025. Over those weeks U.S. distillate stocks fell 1.2 million barrels, when they rose an average of 5.2 million in the previous five summers.
How long will the diesel shortage last?
Probably into 2027. As reported by Reuters on September 21, 2026, EIA forecasts U.S. distillate inventories to stay below their five-year low through the end of 2026 and most of 2027. The supply that went missing is large: Reuters calculated that net diesel exports from Russia and the Gulf were 1.6 million barrels a day lower in August than in February, and damaged refineries take far longer to restore than they took to knock out.
Will diesel prices go down?
EIA projects they will. Its Short-Term Energy Outlook as of October 4, 2026 has U.S. diesel averaging $5.07 a gallon in 2026 and $4.40 in 2027. That is EIA's projection, reissued monthly, not ours.
Which state has the most expensive diesel?
California, at $8.37 a gallon in AAA's survey, against $5.76 in Texas, a spread of $2.61. Every state page on the gas prices hub shows its diesel average next to regular.
Electricity
Are Data Centers Raising Electricity Prices?
Are data centers driving up electricity prices?
The evidence so far says no, but that could change. A June 2026 causal study by EPRI researchers estimates data centers caused average US retail electricity rates to fall modestly from 2015 to 2024, and descriptive state-level comparisons agree that states with more data centers do not have higher or faster-rising rates. Both caution that future supply constraints could reverse the effect.
Why would data centers lower electricity rates?
Grids carry large fixed costs. Durable new demand spreads those costs over more kilowatt-hours, and the study finds economies of scale in transmission, distribution and generation.
When do PJM capacity costs reach household bills?
Capacity charges take effect with each delivery year, which runs June through May. When they appear on a household bill varies by state and supplier; no single region-wide date exists.
Data Center Energy Use
How much electricity do US data centers use?
US data centers consumed an estimated 192 terawatt-hours in 2024, about 4.7% of total US electricity, according to Lawrence Berkeley National Laboratory's 2025 Update.
How much electricity will data centers use by 2030?
LBNL's Reference Case projects 649 TWh in 2030, about 11.8% of forecast US electricity, with a scenario range of 521 to 843 TWh (9.5% to 15.3%).
Do data centers raise electricity prices?
The evidence so far says no, but that could change. A June 2026 causal study by EPRI researchers estimates data centers caused average US retail rates to fall modestly from 2015 to 2024, and state-level comparisons find no positive relationship. Future supply constraints could change that; see our prices page for the evidence.
Electricity Rate Increases by State
Which states had the biggest electricity rate increases in the last year?
Over the 12 months through July 2026, the largest residential rate increases were in Hawaii (+22.0%), New Hampshire (+16.7%), Maine (+15.8%), per EIA monthly retail sales data. The ranked table above covers all 50 states and DC.
Why did my electric bill go up if my utility didn't announce a rate increase?
Base rates are only one piece of a bill. Riders and surcharges, fuel or purchased-power adjustment clauses, and, in retail-choice states, supply prices can all move a bill without a headline rate case. The figures on this page are average effective rates (revenue ÷ sales), so they capture all of those together. The drivers are covered on Why is my electric bill so high?
How current are these numbers?
EIA publishes monthly retail data about two months after the fact; this page shows data through July 2026 and states that month wherever a figure appears. We never project unpublished months, and EIA's revisions are logged on the data updates page.
Are these rates the same as my tariff?
No. These are average effective prices: everything residential customers paid divided by the kWh they used, including fixed charges, riders and taxes collected through rates. Your tariff's marginal price will differ. For your own utility's average, use the ZIP code lookup.
What is the difference between a requested and an approved rate increase?
A utility files a request; the state commission decides. Settlements and final orders routinely cut requested amounts substantially, so summing requested with approved dollars overstates what customers will pay. This page always reports the two separately, and a row moves from requested to approved only when the commission issues its decision.
How does Texas fit in, with its deregulated market?
In most of Texas, the regulated rate case applies to the delivery utility (Oncor, CenterPoint and others), while the supply price comes from competitive retail providers. Texas ledger rows are delivery-charge cases and are labeled as such.
Energy poverty and home-energy burden by state
What is energy poverty in the United States?
The United States has no single federal statutory definition of energy poverty. Federal law uses the phrase once in an international-cooperation finding without defining it; LIHEAP law instead targets low-income households with high home-energy costs relative to income.
What is energy burden?
Energy burden is the share of household income spent on home energy. DOE LEAD uses average housing energy cost divided by average household income and calls 6% or more high burden. Energy Factbook reports that convention but does not adopt a threshold.
Where would the average household's energy bill be highest?
Priced at each state's 2024 residential rates, the average U.S. household's actual fuel purchases would cost the most in Hawaii ($6,886 per year) and the least in North Dakota ($1,718), against $2,495 at national-average prices. This is a pure price comparison; the bundle of fuels is the same for every state.
What is household energy insecurity?
EIA RECS uses household energy insecurity for reported experiences such as reducing food or medicine, keeping the home at an unhealthy temperature, receiving a disconnection notice, or being unable to use heating or air conditioning.
Does this page add gasoline costs to home energy?
No. Gasoline is shown separately as minutes of work per gallon and is never added to the home-energy ratio.
How Much Electricity Does Big Tech Use?
How much electricity does Google use?
Google reported 32.2 million MWh of company-wide electricity consumption in 2024, about 96% of it in data centers, per its 2025 Environmental Report.
How much electricity does Microsoft use?
Microsoft reported 37.0 million MWh of electricity in fiscal year 2025 (ending June 30, 2025), per its 2026 Environmental Data Fact Sheet.
Does Amazon disclose its electricity use?
No. Amazon's sustainability reports state that its electricity is 100% matched with renewable energy but publish no absolute consumption total.
How to Read Your Electric Bill
Can a bill prove that I may choose an electricity supplier?
No. A named third-party supplier or choice notice is a strong clue, but a bundled bill is not proof that choice is unavailable. EIA says to confirm with the distribution utility or state utility commission.
Why can my effective rate exceed the advertised energy price?
The advertised energy price may cover supply only. The effective rate divides current-period total electricity charges, including delivery and other signed line items, by billed kWh.
What should a renter check when electricity comes through the landlord?
Ask whether the unit is individually submetered or the building's master bill is allocated. Texas's submetering rule and master-meter allocation rule illustrate how a commission can regulate the two arrangements; rules vary by jurisdiction.
U.S. Nuclear Power: Capacity, Generation and Plants
Is nuclear power growing in the United States?
Annual net generation is recovering: it increased for 3 consecutive years through 2025, reaching 784.8 TWh, but remained below the 2019 peak of 809.4 TWh. Source: EIA electric power operational data.
How many nuclear plants and reactors are operating in the United States?
The July 2026 preliminary EIA-860M inventory contains 94 reactors with OP status at 54 plants. That matches EIA FAQ 207, which reports 94 operating commercial reactors at 54 plants as of March 2026.
What is the largest U.S. nuclear power plant?
Vogtle is the largest, with four reactors and 4,530 MW of net summer capacity as of March 2026, according to EIA FAQ 207.
Where does the uranium bought by U.S. nuclear plants come from?
In 2025, Canada supplied 32% of purchases, Kazakhstan 28%, Australia 15%, and the United States 7%, according to the EIA Uranium Marketing Annual Report.
When did the United States last complete a nuclear reactor?
Vogtle Unit 4 entered commercial operation on April 29, 2024, according to Georgia Power.
What Is Curtailment?
What is curtailment in electricity?
Curtailment is a deliberate reduction of output from a power plant below what it could have produced, ordered or priced in by the grid operator, most often because supply exceeds demand on the wider system or because a local transmission constraint cannot carry the power away. It is an operating tool, not an outage: the plant is available, and the grid instructs or prices it down.
Why is solar power curtailed?
Mostly timing. Solar output peaks midday, and in spring the combination of strong sun and mild demand produces more midday energy than the system can absorb or export. In the California ISO, March and April are the heaviest curtailment months on average across the series, and EIA reported that 93% of the 3.4 million MWh CAISO curtailed in 2024 was solar (EIA, May 28, 2025).
How much wind and solar is curtailed?
In the California ISO, 154,939 MWh of wind and solar output was curtailed in August 2026, and 4.95 million MWh in 2026 through August (+51% vs the same months of 2025). No comparably clean public series exists for the other U.S. grid operators, so this page does not publish a multi-region total.
What is the difference between generation curtailment and load curtailment?
Generation curtailment reduces a power plant's output; load curtailment reduces customers' consumption. Both words appear in the news as just "curtailment." PJM's board directed a FERC filing on July 27, 2026 under which, during capacity shortages, new large loads (50 MW or more at a site) that do not bring their own generation by June 1, 2027 and have not otherwise secured supply would be curtailed before Pre-Emergency Load Management reaches other customers (PJM).
Is curtailment wasted energy?
Curtailed output is energy a plant could have generated and did not, so nothing is physically consumed or lost; what is forgone is low-cost generation that was available. Whether that is a problem is an economic question about transmission, storage and pricing, and grid operators treat some level of curtailment as a normal, least-cost operating outcome. This page reports the measured quantities and leaves the label to the reader.
What Uses the Most Electricity in a Home?
Does the national ranking describe my particular home?
No. EIA's 2020 RECS estimates a national all-home average. Climate, fuels, equipment and household behavior can change the order for one home.
Is the ZIP utility price my tariff rate?
No. It is an EIA average effective price, calculated as residential revenue divided by sales. It is not an individual tariff or a marginal savings estimate.
Can this table calculate an appliance's hourly cost?
No. Hourly cost depends on the particular unit's wattage. Check its nameplate and its EnergyGuide label; this page does not substitute a national-average end-use share for wattage.
Why Is My Electric Bill So High?
How much of U.S. electricity do data centers use?
About 4.7% in 2024 (192 TWh), per LBNL's 2025 Update. Its Reference Case projects 11.8% by 2030, within a 9.5% to 15.3% scenario range.
Do data centers raise residential electric bills?
In the PJM region, the independent market monitor calculates that including data-center load in the last three capacity auctions' forecasts raised gross capacity-market revenues by $23.1 billion versus reruns without it, a counterfactual result rather than a measured bill impact. The effect varies by region; areas with little data-center growth see less of it.
Why did my bill go up if my usage didn't?
Then the rate or the bill structure changed: a higher per-kWh rate, a higher fixed charge, a new rider, an expired supply contract, or a time-of-use plan. Compare the per-kWh price and fixed charges on this bill to the same month last year.
Will electricity prices go down in 2026?
We track published data rather than forecast. As of July 2026, the U.S. average rate was up +4.9% year over year, and EIA's May 2025 analysis expected retail prices to keep rising through 2026.
Home energy and vehicles
CAFE Standards Explained: U.S. Fuel Economy Rules, 1975–2026
What are CAFE standards?
Corporate Average Fuel Economy (CAFE) standards are federal rules, set by NHTSA under a 1975 law, that require each automaker's new cars and light trucks to meet a sales-weighted average fuel economy. Each automaker's target depends on the size (footprint) of the vehicles it sells, so there is no single mpg number every company must hit.
What mpg does the law require now?
Until the new rule takes effect, the standards in force are those of the 2024 rule, which projected 50.4 mpg (projected fleet average, model year 2031, lab compliance test, with AC and off-cycle credits). NHTSA signed the final rule on September 25, 2026 and posted the signed text on its website. As of September 28, 2026, it had not yet been published in the Federal Register; it takes effect 60 days after publication. The final rule projects 34.9 mpg (projected fleet average, model year 2031, lab compliance test, without AC and off-cycle credits) (NHTSA signed final rule (pre-publication text), pp. 26, 54).
Why is CAFE mpg higher than my window sticker?
CAFE uses an older two-cycle lab test. The window sticker uses a five-cycle test meant to reflect real driving, and NHTSA says real-world fuel economy is generally 20 to 30 percent lower than compliance values. EPA's 2024 Prius example: 80 mpg (lab compliance test), 57 mpg (window-sticker rating), 56 mpg (EPA real-world estimate).
Is there an EV mandate?
Technically, no. In practice, the federal standards were built so that automakers could meet them only by selling large numbers of electric vehicles. No federal rule required a set share of EV sales, and NHTSA and EPA each said so in their 2024 rules. But EPA's 2024 greenhouse-gas rule projected electric vehicles, including plug-in hybrids, at 68% of new sales by 2032 (89 FR 28087), and NHTSA's 2024 CAFE rule projected battery-electric vehicles at about 28% of new vehicles by 2031 (89 FR 52737). EPA said most of that shift would come from market forces such as the federal EV tax credits, which ended in September 2025 (89 FR 28057). NHTSA's 2026 final rule concludes the earlier CAFE standards were not attainable for the gasoline- and diesel-powered fleet. California's Advanced Clean Cars II rule does mandate EV sales, rising to 100% of new cars and light trucks by 2035; Congress disapproved its federal waiver in 2025, and that is in litigation.
Do CAFE standards raise car prices?
The price data alone cannot answer that. Relative to overall inflation, BLS's quality-adjusted new-vehicle prices fell about 3.3% a year from 1998 to 2008, then fell about 0.4% a year from 2009 to 2016. Several things changed around 2008 at once, including the recession, the GM and Chrysler bankruptcies and new fuel economy rules. The analysis section of this page summarizes the argument that the standards raised prices and EPA's rebuttal.
What happens if automakers miss the standard?
They can use credits earned in other years or bought from other automakers. Until 2025, any remaining shortfall meant a civil penalty; Fiat Chrysler (now Stellantis), for example, paid penalties for model years 2016 through 2018. Congress set the CAFE civil penalty to $0.00 in July 2025. The change covers cases in which NHTSA had not yet sent a penalty notice.
What did the Trump administration change in 2026?
NHTSA signed the final rule on September 25, 2026 and posted the signed text on its website. As of September 28, 2026, it had not yet been published in the Federal Register; it takes effect 60 days after publication. NHTSA projects the final standards at 34.9 mpg (projected fleet average, model year 2031, lab compliance test, without AC and off-cycle credits), compared with 49.3 mpg (projected fleet average, model year 2031, lab compliance test) under the 2024 standards. The rule, once in effect, revises standards back to model year 2022, ends trading between automakers for credits earned from 2028, and moves many crossovers into the passenger-car class from 2030. From 2028 NHTSA also leaves air-conditioning and off-cycle credits out of the analysis it uses to set the standards; EPA's credit programs are unchanged.
Does the rollback affect gas prices?
Not directly. CAFE governs how efficient new vehicles are, which affects how much fuel drivers buy over many years, not the price of a gallon. NHTSA projects 4.6% more gasoline use through 2050 than under the 2024 standards (NHTSA signed final rule (pre-publication text), p. 55).
Global EV Sales
What percentage of cars sold worldwide are electric?
24% of global new-car sales in the first half of 2026 were electric (battery-electric plus plug-in hybrid), one point higher than a year earlier. The IEA expects about 29%, roughly 23 million cars, for the full year (IEA, Electric Car Markets in a Time of Uncertainty, July 2026).
What share of new cars in China are electric?
Over 60% in the second quarter of 2026, and the IEA expects the full-year share to exceed 60% for the first time, on about 13.2 million electric car sales, similar to 2025.
Why are Chinese EV exports rising so fast?
Domestic Chinese car sales fell over 20% year on year in the first half of 2026, and manufacturers shifted to export markets: total car exports grew 65% and electric car exports over 120%, taking electric cars to more than 45% of China's car exports. The IEA also estimates over 1 million exported electric cars had not yet been registered as sales anywhere, pointing to inventory build-ups abroad.
Is a Heat Pump Worth It in 2026?
Is there still a federal tax credit for heat pumps?
Not for a system placed in service in 2026. The Energy Efficient Home Improvement Credit (Section 25C), which was worth 30% of the cost up to $2,000 for a qualifying heat pump, applies only to property placed in service before December 31, 2025, per the IRS. state rebate programs funded by the Inflation Reduction Act are separate and some are still running, so check your state before assuming there is nothing available.
Is a heat pump cheaper to run than what I have now?
It depends entirely on what you heat with. On this season's prices a heat pump costs less to run than propane in 38 of 38 states with data, less than heating oil in 21 of 21, and less than electric baseboard heat in all 51. Against natural gas it wins in only 20 of 51 states. Find your state in the table above.
Why does a heat pump beat electric baseboard heat by so much when both run on electricity?
A heat pump moves heat instead of creating it. We use a coefficient of performance of 2.8, meaning 2.8 units of heat per unit of electricity, from ENERGY STAR, so it uses about a third of the power for the same warmth. Nationally that is $18.7/MMBtu against $52.2/MMBtu for resistance heat, or about $1,675 a season on a typical 50 MMBtu heating load.
If natural gas is cheaper, is a heat pump still worth considering?
Running cost is one input. A heat pump also provides cooling, which a furnace does not, so if you would otherwise buy both a furnace and an air conditioner the comparison changes. Gas prices and electricity rates also move at different speeds. This page reports the running-cost math; the equipment decision includes factors we do not measure.
What do heat pumps cost to install?
We do not publish a national average, because quotes vary widely by home, system size, ductwork, and region, and a single figure would mislead more than it helps. The largest U.S. study of the question, a simulation of 550,000 representative households published in Joule in 2024, reports bill savings but likewise publishes no single national installed cost, naming high installation cost as the main barrier. The calculator on this page takes your own quote and returns the payback using your state's measured running-cost saving.
Is Solar Worth It in 2026?
Is there still a 30% federal tax credit for solar?
Not for a system placed in service in 2026. The Residential Clean Energy Credit (Section 25D) was worth 30% of the cost of a home solar installation, and the IRS states that it "is not available for any property placed in service after December 31, 2025." State and utility incentives are separate and still exist in many places.
How much did losing the credit change the math?
It raises the effective cost of any quote by about 43%, because you now pay the whole price instead of 70% of it. On an illustrative $25,000 system producing 11,000 kWh a year, payback in United States goes from about 8.7 years to about 12.4. The percentage is the same everywhere; the number of years it adds depends on your electricity rate.
Where does solar pay off fastest?
Wherever electricity is most expensive, because every kWh your panels make is a kWh you do not buy. Residential rates run from 48.00¢/kWh in Hawaii down to 12.72¢/kWh in Louisiana, a spread of about 3.8 times, per EIA. That spread matters more than the difference in sunshine between most states.
Does it matter what my utility pays for power I export?
Yes, and it can change the answer. Under full retail net metering an exported kWh is worth the same as one you use. Under net billing, which California and a growing number of states have moved to, exports are credited well below retail, so the value of solar depends on how much you consume on site. We do not track those rules state by state; the DSIRE database maintains them.
What does a home solar system cost?
We do not publish a national average. Quotes vary by roof, system size, equipment, and installer, and the figures published by installers are marketing. The calculator on this page uses your own quote and your own quote's production estimate, applied to your state's measured electricity rate.
U.S. EV and Hybrid Sales
What percentage of new vehicles sold in the U.S. are electric?
In August 2026, plug-in vehicles (battery-electric plus plug-in hybrid) were 7.7% of new light-duty vehicle sales and conventional hybrids were 15.7%. Across 2026 through August, the shares are 7.3% plug-in and 15.5% hybrid, 22.8% combined (Argonne National Laboratory monthly sales data).
Do hybrids outsell electric cars in the U.S.?
Yes. In 2026 through August, hybrids outsold plug-ins 2.1 to 1 (1,656,764 hybrids vs 778,185 plug-ins). The lead has changed hands: plug-ins outsold hybrids in 2022 and 2023, hybrids retook the lead in 2024 and have widened it since.
Why did plug-in sales fall in late 2025?
The plug-in share of new sales peaked at 12.9% in September 2025 and fell to 5.2% by November. The federal credit of up to $7,500 for new clean vehicles ended for vehicles acquired after September 30, 2025, under Public Law 119-21 (IRS). This page reports the dated series and does not estimate how many sales the credit caused.
How many electric vehicles have been sold in the U.S.?
8,590,296 plug-in vehicles were sold from December 2010 through August 2026, summing Argonne's monthly table. The count starts with the first mass-market plug-ins in December 2010.
What share of cars worldwide are electric?
Electric cars were 24% of global new-car sales in the first half of 2026, and the IEA expects 29% for the full year. China is above 60%. See global EV sales (IEA, July 2026, CC BY 4.0).
What It Costs to Heat a Home, by Fuel and State
Why is a heat pump so much cheaper to run than electric baseboard heat?
A heat pump moves heat rather than making it, delivering about 2.8 units of heat per unit of electricity, so it uses roughly a third of the power for the same warmth. This past season that made heat-pump heat about $18.7 per million Btu nationally, versus about $52.2 for electric resistance, roughly 2.8 times cheaper.
Is propane more expensive than natural gas for heating?
Almost always, per unit of heat. This past season propane delivered heat cost about $30.3 per million Btu nationally versus about $16.3 for natural gas, because propane is sold by the gallon and trucked in. Many rural homes use propane only because no natural gas line reaches them.
How do I compare a price per gallon of oil to a price per Mcf of gas?
Convert both to delivered heat. A gallon of heating oil holds about 0.1385 million Btu and a thousand cubic feet (Mcf) of natural gas about 1.037 million Btu; divide the price by the heat content times the furnace efficiency. This page does that for every fuel so the columns are directly comparable. One Mcf is about 10.37 therms.
U.S. and world energy
Does a higher quality of life mean cleaner air?
Do richer countries have cleaner air?
Largely yes for the air people breathe. Median PM2.5 exposure falls from about 38.5 µg/m³ in the least-developed countries to roughly 10.2 in the most developed, as wealthier nations adopt scrubbers, cleaner fuels and emission standards.
Which developed country has the cleanest air pollution record?
Among very-high-development countries in 2022, Switzerland emits the least, about 5.9 kg of SO₂ and NOₓ per person. Switzerland, the Netherlands, the UK and Sweden lead the group.
Which developed countries emit the most air pollution per person?
Oil- and gas-rich states top the list: Kuwait emits about 169.0 kg of SO₂ and NOₓ per person, with Saudi Arabia, Qatar and the UAE close behind, and their populations also breathe some of the world's highest PM2.5 levels.
What is the environmental Kuznets curve?
The idea that pollution rises during early industrialisation, then falls once a country is rich enough to invest in cleaner technology and demand better air. SO₂ and NOₓ emissions per person follow this inverted-U; per-person carbon emissions are far less likely to.
Can a country emit a lot of air pollution but still have clean air?
Yes. Australia emits a lot of SO₂ and NOₓ per person but has very low PM2.5 exposure because emissions disperse over a large, sparsely populated area. The air pollution people breathe depends on where and how densely it is emitted, not just the national total.
Top oil, gas, and coal producing countries
Which country produces the most oil?
United States was the largest oil producer in 2025, at about 21,065 thousand barrels per day, roughly 20.9% of world output, ahead of Saudi Arabia and Russia.
Which country produces the most natural gas?
United States led natural gas production in 2025 with about 1,074 billion cubic metres (25.6% of the world), followed by Russia.
Which country produces the most coal?
China dominates coal production, mining about 4,663 million tonnes in 2025, roughly 52.4% of world output.
How much oil, gas and coal does the world produce?
In 2025 the world produced about 100,590 thousand barrels of oil per day, 4,196 billion m³ of gas, and 181 EJ of coal.
U.S. Energy Facts & Statistics
How much energy does the United States produce and consume?
In 2025 the U.S. produced 107.16 quadrillion Btu of primary energy and consumed 96.47, per the EIA Monthly Energy Review. A quad is a quadrillion British thermal units. Producing more than it consumes makes the country a net energy exporter.
Is the U.S. a net energy exporter?
Yes. Net energy imports were -11.10 quads in 2025, a negative number meaning exports exceeded imports, which has been true every year since 2019.
What is the largest source of U.S. electricity?
Natural gas, at 40.8% of 2025 generation (1,807.3 terawatt-hours), per EIA. The full mix is in the table above.
How much of U.S. energy is renewable?
Renewables were 8.84 quads of consumption in 2025, 9.2% of the total. That figure combines five sources that behave differently: biofuels 29.1%, wood 21.6%, wind 17.9%, solar 16.3%, hydroelectric 9.5%, waste 4.2%, geothermal 1.4% of the renewable total. We show them separately for that reason.
Why do the numbers on this page have different dates?
Because the underlying series do. The Monthly Energy Review annual totals, electricity generation, and the weekly and monthly price series all publish on their own schedules. Every figure here is labeled with the period it covers rather than a single site-wide date that would be wrong for most of them.
What percentage of the world’s electricity comes from fossil fuels?
What percentage of the world's electricity comes from fossil fuels?
In 2025, fossil fuels generated about 56.7% of global electricity: coal 32.6%, natural gas 21.9% and oil 2.2%.
What percentage of electricity is low-carbon?
About 42.2% of world electricity came from low-carbon sources in 2025: nuclear 8.8%, hydro 13.9%, and wind, solar and other renewables 19.5%.
Why is electricity less fossil-dependent than total energy?
Electricity is only about a fifth of final energy use and is where low-carbon sources concentrate, so it is 56.7% fossil, below the 86.2% fossil share of total energy, which also includes transport, heating and industry.
Is coal still the biggest source of electricity?
Yes. Coal remained the single largest source of world electricity in 2025 at 32.6%, ahead of natural gas at 21.9%.
Which countries have the lowest-carbon electricity?
Countries with large hydro or nuclear fleets, such as Iceland, Norway, France and Sweden, have the lowest fossil share of electricity. Sort the table above ascending by fossil share to see them.
What percentage of the world’s energy comes from fossil fuels?
What percentage of the world's energy comes from fossil fuels?
In 2025, fossil fuels (oil, natural gas and coal) supplied about 86.2% of the world's total primary energy.
What percentage of world energy comes from oil, coal and gas individually?
Oil supplied 33.5%, coal 27.7%, and natural gas 25.1% of total primary energy in 2025.
Is the world using more or less fossil fuel?
Both can be true at once. The fossil-fuel share of energy has slipped since 2010, but the absolute amount of fossil fuel burned has risen, because total energy demand has grown faster than wind and solar have been added.
Is this the same as electricity?
No. Electricity is only about a fifth of final energy use. This figure covers total primary energy, including transport fuels, industrial heat and building heating, which are far more fossil-dependent than the power sector.
Is nuclear or biomass a fossil fuel?
No. Fossil fuels are oil, natural gas and coal. Nuclear, hydro, wind, solar, geothermal and biomass are all counted as non-fossil energy.
Which country depends most and least on fossil fuels?
It varies widely. Countries with abundant hydro, nuclear or geothermal power (such as Iceland, Sweden, France and Norway) have the lowest fossil shares, while many oil- and gas-producing economies sit near the top. See the country table above.
Which countries deliver a high quality of life with the least carbon?
Which countries deliver the highest quality of life with the least carbon?
Among very-high-development countries in 2022, Sweden is the most carbon-efficient, reaching an HDI of 0.952 on about 3.63 tonnes of CO₂ per person. Sweden, Switzerland, France and the United Kingdom lead this group.
Which developed countries emit the most carbon for their quality of life?
Oil- and gas-rich states top the list: Qatar emits about 37.53 tonnes of CO₂ per person, roughly 11 times Sweden's, for a similar level of human development. Kuwait, Bahrain and the UAE are close behind.
What is the Human Development Index (HDI)?
HDI is a UN measure combining life expectancy, education and income into a single score from 0 to 1. ‘Very high human development’ means an HDI of 0.80 or above.
Does a higher quality of life require more emissions?
Only up to a point. Below moderate development, emissions and HDI rise together, but above an HDI of about 0.8 the link breaks down: countries reach the top of the development scale on anywhere from 4 to 40 tonnes of CO₂ per person, depending on their energy mix.
Why does the ranking exclude low-income countries?
A very poor country can show near-zero emissions simply because it has little energy use, which would wrongly read as efficient. Limiting the ranking to HDI ≥ 0.8 measures carbon-efficiency among countries that have actually achieved a high quality of life. All 101 countries appear in the chart.
Which countries produce oil, gas and coal with the lowest greenhouse-gas emissions?
Which country produces oil and gas with the lowest emissions?
Of major producers, Norway has the lowest upstream emissions in 2025, about 0.9 kg of CO₂-equivalent (from flaring and methane) per barrel of oil-equivalent produced, against a world average of 57.5 kg.
Which country produces oil and gas with the highest emissions?
Venezuela had the highest production emissions intensity at about 215.2 kg CO₂e/boe, roughly 239 times Norway's, driven by methane leakage and gas flaring.
What counts as production (upstream) emissions?
These are greenhouse gases released from extracting and processing fuel, before it is burned: methane vented or leaked from wells, pipelines and coal mines, plus carbon dioxide from flaring unwanted gas. They are separate from the much larger emissions released when the fuel is finally combusted, and separate from air-quality pollution.
Why does methane matter so much?
Methane traps roughly 80 times as much heat as CO₂ over a 20-year period, so even small leaks have an outsized warming effect. Cutting methane from fossil-fuel operations is one of the fastest ways to slow warming.
How much gas does the world flare?
About 162.6 billion cubic metres in 2025: energy wasted and CO₂ emitted for no useful output. Flaring has barely declined in 30 years.
Which countries’ energy creates the most air pollution?
Which countries' energy produces the most air pollution?
In 2022, Pakistan's energy was the most polluting of major energy users, emitting about 1099.6 grams of sulfur dioxide and nitrogen oxides per gigajoule, roughly 19 times Netherlands's 56.8 g/GJ.
Which countries have the cleanest energy for air quality?
Advanced economies with scrubbers, gas and nuclear, led by Netherlands and including the Netherlands, Germany, the United States and France, emit the least SO₂ and NOₓ per unit of energy.
What air pollutants come from energy?
Burning coal, oil and gas releases sulfur dioxide (SO₂), nitrogen oxides (NOₓ), fine particulate matter (PM2.5) and other pollutants. SO₂ and NOₓ also react in the air to form more particulates and ozone, the main drivers of smog and acid rain.
Is air pollution the same as carbon emissions?
No. Carbon dioxide is a greenhouse gas that warms the climate but is harmless to breathe. SO₂, NOₓ and particulates are air-quality pollutants that directly harm health. A country can have high carbon emissions yet relatively clean local air, or both problems at once.
Does more polluting energy mean worse air to breathe?
Largely yes. The countries whose energy emits the most SO₂ and NOₓ also tend to have the highest PM2.5 exposure, for example Pakistan at 57.1 µg/m³, far above the WHO guideline of 5.

What Is the AQI? The Scale, How It's Calculated, and How EPA Changed It
What is a good AQI?
0 to 50. AirNow calls that range Good: "Air quality is satisfactory, and air pollution poses little or no risk." 51 to 100 is Moderate.
What AQI is unhealthy?
Above 100. 101 to 150 is Unhealthy for Sensitive Groups, 151 to 200 is Unhealthy, 201 to 300 Very Unhealthy, and 301 and above Hazardous.
Is an AQI of 100 bad?
100 is the top of the Moderate range. For each pollutant, an AQI of 100 generally corresponds to the level of its short-term national health standard, so 100 means the air is at about that level, not above it.
What does Code Orange mean?
An AQI forecast of 101 to 150, Unhealthy for Sensitive Groups. Some areas call an air quality action day at Code Orange; AirNow's advice is for people sensitive to the pollutant to reduce prolonged or heavy exertion outdoors.
What does Code Red mean?
An AQI forecast of 151 to 200, Unhealthy. AirNow says many places call action days at this level and that everyone should reduce exposure, especially sensitive groups.
What pollutants are in the AQI?
Five: ground-level ozone, particle pollution (fine PM2.5 and coarse PM10, scored separately), carbon monoxide, sulfur dioxide and nitrogen dioxide. The day's AQI is the highest of their scores, not a sum.
Did EPA change the AQI?
Yes. It moved the line for 100 for fine particles (effective 2013) and for ozone (2015), and in May 2024 lowered the top of the Good range for fine particles from 12.0 to 9.0 µg/m³. The same air can score higher today than it would have before. How much, metro by metro.
Why does AirNow show a different AQI from the daily number?
AirNow, EPA's air quality website and app, shows the NowCast, an estimate for the most recent hour, alongside forecasts for the next day. The official daily AQI for particles uses a 24-hour average, which can't be calculated until the day is over. The particle NowCast is a weighted average of the past 12 hourly readings, so a mid-afternoon reading and the day's final AQI can differ.

Why Is Gas So Expensive in California? 5
/gas-prices/california/why-expensive/
Why is California gasoline so expensive?
In AAA's October 04, 2026 averages California is the most expensive state, and in EIA's survey it ran $1.724 a gallon above the U.S. in the week of 2026-09-28. The sourced explanations are higher state taxes, two carbon programs, a state-specific fuel blend, and an isolated refining system that has lost two refineries. No source on this page assigns a share of this week's price to each of them.
How much of the price is tax?
73.6 cents per gallon in state taxes and fees (Tax Foundation, 2026 edition), against an unweighted mean of 33.6 cents among the 50 states, plus the federal excise of 18.4 cents that every state pays. Source.
What does cap-and-trade add?
About 23 cents per gallon at February 2025 allowance prices, by the Legislative Analyst's Office's May 2025 estimate, rising to 74 cents only if allowances reached the price ceiling. DPMO's Exhibit A6 carries $0.23 per gallon as of August 2025. Source. Source.
What does DPMO mean by its unexplained price difference?
The part of California's premium over other states that remains after DPMO nets out taxes, fees, environmental programs and its fuel-specification allowance. Between 2015 and 2024, the mystery gasoline surcharge averaged $0.41 per gallon, costing Californians $59 billion. On the industry side it reports: California gross gasoline industry margins increased by $0.35 per gallon relative to the rest of the U.S. since the surcharge appeared. Source.
Will refinery closures raise prices?
Phillips 66 Los Angeles (139,000 b/d): Fuel production ceased in the fourth quarter of 2025; facilities idled. Valero Benicia (145,000 b/d): Refining operations ceased; phased idling completed by the end of April 2026. EIA's July 2025 analysis said the two represented 17 percent of California capacity and 11 percent of the West Coast's, that the region lacks pipeline links to other refining hubs, and that gasoline imports ran above 210,000 b/d in late May 2025.
