Particularly high refinery margins for distillate fuel oil and jet fuel have contributed to shifts in the refinery yields of major products in 2026. Data from our latest Petroleum Supply Monthly—which includes data through August 2026—indicate refinery yields of gasoline have decreased significantly this year to support increased production of distillate fuel oil and jet fuel, sometimes referred to as middle distillates due to their relative cut points in the oil refining process.

Global crude oil refinery inputs fell by 4.8 million barrels per day (b/d) in the second quarter of 2026 (2Q26), or 6%, following the start of conflict in late February in the Middle East, according to data from Kpler. Throughput then increased by 1.8 million b/d in the third quarter, primarily as refiners in the region adjusted to new trade flows.

Utility-scale solar developers are increasingly co-locating battery storage with new solar photovoltaic capacity. As of September 2026, over 16% of new utility-scale solar capacity added this year is co-located with operable battery storage, compared with 2% in 2017, according to data reported to EIA by operators.

Colombia is importing more liquefied natural gas (LNG) as domestic production continues to fall. A potential drought this fall and winter could limit the availability of hydroelectric generation and boost the country's demand for natural gas power generation. Colombia's government has declared a national disaster in anticipation of a drought resulting from an expected strong El Niño.

The U.S. refinery fleet has run at higher-than-normal rates this year, with refinery utilization averaging more than 95% of capacity between May and September, the highest for those months since 1998. Tight global product supplies this year have boosted margins for petroleum products, particularly for diesel, incentivizing the increased run rates.

In the third quarter of 2026 (3Q26), 23% of new light-duty vehicles sold in the United States were hybrid electric, battery electric, or plug-in hybrid electric vehicles, down slightly from 24% in 3Q25. Between 3Q25 and 3Q26, hybrid electric vehicles continued to gain market share, reaching 16% of light-duty vehicle sales. Growth of hybrid electric vehicle sales has slowed this quarter as the average transaction price for a new vehicle passed $50,000-the first time this price has been reached so far this year, according to Kelley Blue Book.

We estimate that U.S. generation from small-scale or rooftop solar photovoltaic systems (smaller than 1 megawatt of capacity) has increased from 18,812 gigawatthours (GWh) to 92,979 GWh over the last decade. The four states with the highest generation of small-scale solar in the country-California, Arizona, Texas, and Florida-are in regions with more abundant solar resources. Even though it is in a region with lower solar resources, New York ranks as the fifth-largest rooftop solar generation producer as a result of capacity growth supported by technology improvements and state incentives.

Three regional transmission organizations (RTOs) set records for peak hourly load this past summer, according to data reported on Form EIA-930 and presented in the Hourly Electric Grid Monitor.

Monthly wind generation in the first nine months of 2026 was an average of 68% higher compared with the same period in 2025 in ISO New England (ISO-NE).

As of 4:00 a.m. central time on October 9, the National Oceanic and Atmospheric Administration expects Hurricane Isaias to make landfall on the Gulf Coast late Friday or early Saturday, creating the potential for significant disruptions to energy infrastructure. Hurricane Isaias is the first hurricane of the 2026 Atlantic season and will be the largest storm system to make landfall in the region since Hurricane Helene in September 2024.

We expect energy expenditures this winter to vary because of diverging trends in energy prices among fuels and regional variation in forecast temperatures. We expect that lower prices for natural gas and propane will drive decreases in expenditures this year for the half of U.S. households heating with those fuels. Higher prices for electricity and heating oil drive increased expenditures for households heating with those fuels in our forecast.

Petroleum markets in the third quarter of 2026 (3Q26) were characterized by increasing prices for crude oil and petroleum products amid persistent conflict in the Middle East.

U.S. natural gas production hit an all-time high in July 2026, driven primarily by increased output in the Permian Basin, according to our latest Natural Gas Monthly.

U.S. propane exports increased to 2 million barrels per day (b/d) in the first half of 2026, 11% more than during the same period in 2025. Increased U.S. propane production and changing trade flows, particularly increased exports to India and other countries in South Asia, drove propane exports to a record high of 2.1 million (b/d) in April 2026. Since then, total propane exports, including exports to India, have continued at levels well above the five-year average.

We estimate light-duty electric vehicles in the United States consumed 8% more electricity during the first six months of 2026 than in the last half of 2025 (2H25) in our Monthly Energy Review, down from the 13-24% growth seen in six-month periods in recent years. The slowing electric vehicle electricity consumption growth followed a decline in sales after U.S. federal tax credits expired in September 2025. Overall, U.S. light-duty electric vehicle electricity use has more than doubled since 1H23, totaling nearly 14 billion kilowatthours in 1H26.

The Henry Hub natural gas spot price averaged $2.93 per million British thermal units from June through August, 6% less than the same period last year. Prices were lower this summer despite exceptionally hot weather that increased electricity demand for air conditioning. Natural gas-fired power plants often help meet higher demand during such periods.

Publicly traded companies represent a tiny share of the total number of companies producing crude oil and natural gas in the United States, but they make up a large share of U.S. production. In 2025, publicly traded companies accounted for just 2% of about 12,000 oil and natural gas producers but produced 68% of the crude oil and natural gas in the Lower 48 states.

The price of distillate fuel oil, often sold as diesel, is driven by the price of crude oil, retail margins, distribution costs, taxes, and crack spreads, the indicator we use for refining margins. Tight global supplies of distillate fuel oil and elevated crude oil prices have driven prices higher in recent months.

On August 28, 2026, Cheniere Energy, Inc., completed its Corpus Christi Liquefaction Stage 3 Project (CCL Stage 3) in Texas, taking custody and control of the seventh and last liquefied natural gas (LNG) train in the project.

We forecast U.S. crude oil production will average 13.8 million barrels per day (b/d) in 2026, surpassing the previous record of 13.7 million b/d set in 2025, in our latest Short-Term Energy Outlook (STEO).
