In-brief analysis

October 10, 2025

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.

Evolving trends in home heating fuels reflect shifts in housing populations, changes in technology and policy, and decisions by households and home builders. The center of American population continues to generally move west and south, from areas with colder weather to areas with warmer weather. As that population has shifted, overall demand for space heating has declined.

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.

We estimate global petroleum inventories rose by an average of 1.8 million b/d in the second and third quarters in our October Short-Term Energy Outlook (STEO). Global oil inventories have been growing in 2025 as crude oil production from OPEC+ members and non-OPEC+ producers in North and South America has outpaced global demand

Researchers at Columbia have created a chip that turns a single laser into a “frequency comb,” producing dozens of powerful light channels at once. Using a special locking mechanism to clean messy laser light, the team achieved lab-grade precision on a small silicon device. This could drastically improve data center efficiency and fuel innovations in sensing, quantum tech, and LiDAR.
