When the International Maritime Organization's lower marine sulfur limit known as IMO 2020 took effect in January 2020, commercial shippers pivoted sharply to fueling their vessels with low-sulfur fuel oil (LSFO). In the years since, high-sulfur fuel oil has reclaimed some market share, as a growing number of commercial vessels install sulfur scrubbers that allow operators to use the heavier, cheaper fuel oils while complying with the new sulfur emission limits.

According to data released by the U.S. Census Bureau in September, the United States exported 46.8 million short tons (MMst) of coal in the first half of 2025 (1H25), an 11% decline from 1H24.

Companies operating in Brazil have expanded the country's liquefied natural gas (LNG) regasification infrastructure since 2020, more than doubling its import capacity as the country seeks to diversify its energy supply and enhance energy security. Brazil's regasification capacity grew from 2.5 billion cubic feet per day (Bcf/d) in 2020 to 5.1 Bcf/d in August 2025.

The pace of capacity additions for U.S. biofuel production slowed in 2024, with production capacity increasing by a modest 3% from the start of 2024 to the start of 2025, according to our latest biofuels production capacity reports. A deceleration in production capacity in our category renewable diesel and other biofuels accounted for most of slowdown in growth. Sustainable aviation fuel (SAF), renewable naphtha, and renewable propane make up virtually all of the other biofuels.

Since 2021, electricity demand within the Texas electricity grid operated by the Electric Reliability Council of Texas (ERCOT) has steadily increased. In the first nine months of 2025, electricity demand in ERCOT, which manages about 90% of the state's load, reached a record high compared with the same period in previous years. Over those same months, ERCOT had the fastest electricity demand growth among U.S. electricity grids between 2024 and 2025. From January through September 2025, demand for electric power in ERCOT increased 5% compared with the same period in 2024 to 372 terawatthours (TWh), 23% more than the same months in 2021. Since 2023, wind and solar generation, especially utility-scale solar, have been the fastest-growing sources of electricity in ERCOT and are increasingly meeting rising demand.

The United States is on track to export a record amount of fuel ethanol for the second year in a row in 2025, driven by growing international demand. This growing market for exports is supporting increased U.S. fuel ethanol production, even as domestic consumption stagnates.

U.S. natural gas pipeline exports to Mexico averaged 7.5 billion cubic feet per day (Bcf/d) in May 2025, the most of any month on record as Mexico's demand for natural gas, particularly in the electric power sector, increases. On an annual basis, U.S. natural gas pipeline exports to Mexico averaged 6.4 Bcf/d in 2024, a 25% increase compared with 2019 and the highest on record in data going back as early as 1975.

Liquefied natural gas (LNG) exporters in the United States have announced plans to more than double U.S. liquefaction capacity, adding an estimated 13.9 billion cubic feet per day (Bcf/d) between 2025 and 2029, according to our Liquefaction Capacity File and trade press reports. The United States is already the largest exporter in the world with 15.4 Bcf/d of capacity.

We expect energy expenditures this winter will vary based on a home's main space heating fuel: homes heating with natural gas will pay about the same amount for natural gas as they did last winter, but homes heating with electricity will pay more than they did last winter. Homes heating with propane or heating oil will pay less than they did last winter.

U.S. ethane exports are poised for significant growth through 2026, driven by robust global demand for ethane as a petrochemical feedstock, substantial U.S. export capacity expansions, and larger vessels to carry ethane exports. In our October Short-Term Energy Outlook, we forecast U.S. ethane net exports will grow 14% in 2025, followed by a 16% rise in 2026. The United States does not import ethane.

An increasing share of U.S. households are using electricity for heating, although natural gas remains the most common heating fuel. In 2024, 42% of U.S. households reported that electricity was their main space heating fuel, according to annual estimates from the U.S. Census Bureau's American Community Survey. Natural gas was the main heating fuel in 47% of homes last year, a decline from 49% in 2010.

We estimate crude oil inventories in China increased by about 900,000 barrels per day (b/d) between January and August this year, essentially acting as a source of demand by removing barrels from the global markets. The stock builds in China limited the downward price pressure we would otherwise expect to see with growing inventories, keeping the Brent crude oil spot prices in a relatively tight range around $68 per barrel (b) in the second and third quarters of 2025.

The United States is well stocked with propane heading into the winter. For the week ending September 26, U.S. propane inventory was 103 million barrels, about 13 million barrels more than the previous five-year average for this time of year, based on data in our Weekly Petroleum Status Report.

Crude oil prices were relatively stable in the third quarter of 2025 (3Q25), ending the quarter just 9 cents per barrel (b) less than they started, while refinery margins increased to their highest levels so far this year. In this quarterly update, we review petroleum markets price developments in 3Q25, covering crude oil prices and refinery margins.

The value of all energy trade between the United States and Mexico was estimated to be $57 billion in 2024, down from nearly $72 billion in 2023, according to data from the U.S. Census Bureau. A combination of lower petroleum output from Mexico and lower fuel prices, particularly for petroleum products that make up the bulk of the cross-border energy trade between the two countries, drove most of the decrease.

In 2023, Texas consumed more energy than any other state. Total energy consumption in Texas was twice as much as in California, the second-highest consuming state, and more than three times as much as in Florida, the third-highest consuming state, according to recently released data in our State Energy Data System (SEDS). U.S. total energy use peaked in 2007, and between 2007 and 2023, Texas's energy consumption increased 21%, while U.S. energy use decreased 5%. According to our SEDS data, most of the energy consumption growth in Texas is attributable to increased industrial activity, population, and electricity demand.

Two electricity markets in the Midwest still generate more electricity from coal than from natural gas in at least some months of the year: Southwest Power Pool (SPP) and the Midcontinent Independent System Operator (MISO). We expect these two regions will generate more electricity from coal than from natural gas in some upcoming winter months, based on forecasts in our latest Short-Term Energy Outlook.

Growth in distributed solar generation capacity has driven growth in total electricity generation capacity in Brazil since 2019. Distributed solar generation capacity grew from less than 1 gigawatt (GW) in 2018 to 40 GW in 2025 through June, accounting for 43% of all electricity capacity additions over that period.

In our September Short-Term Energy Outlook, we forecast U.S. total distillate inventories to end 2025 and 2026 at lower levels than previous years because of significant inventory draws in 2025, strong export demand, and domestic production declines stemming from refinery closures. In the weeks since the publication of this forecast, U.S. distillate inventories have increased substantially, but they remain relatively low. Distillate fuel oil includes both diesel fuel used in vehicles and home heating oil. Lower distillate inventories elevate the risk of higher prices and price volatility from supply disruptions, especially during periods of high demand like the autumn harvest and winter heating season.

In our annual survey of power plant activity, we ask operators of utility-scale batteries how they are using their systems, and one use case is increasingly prevalent: price arbitrage. Arbitrage involves buying electricity when prices are relatively low and selling that electricity when prices are high.
